Learning Makes Me Rich

Chapter 172

In November, Zhou Xiu finished the last set of questions and was about to go to City B to participate in the National Mathematics Competition for Middle School Students.

National Middle School Students Mathematics Winter Camp, referred to as CMO, the top 60 contestants with the best scores will form a national training team. The competition entered the CMO, where the strongest students from provinces from all corners of the country gathered to compete in the same field. The difficulty was very high, and it was very difficult to win the gold medal.

The gap exists not only between strong and weak provinces in education, but also among the members of a provincial team.

Although Zhang Qi was lucky enough to win the provincial first prize in the league with Zhou Xiu's notes, he missed the chance to enter the provincial team. Xu Haobo also failed in the selection of the provincial team. The provincial team has a total of 15 people, 8 of which are from the No. 4 middle school. Only Zhou Xiu, Xi Shaoyuan, and Xie Cheng from Yude entered the provincial team.

Zhang Qi himself said that he didn't mind, and he said with a smile: "I am very lucky to get the provincial one."

The provincial team is a place where gods fight. Zhang Qi did not take the college entrance examination, and getting the provincial first grade can be regarded as fulfilling his dream of competing for many years. Xu Haobo expressed his satisfaction. He plans to stay in China to study, and the provincial first prize will allow him to get extra points in the independent enrollment of colleges and universities.

Before departure, Yude generously gave three students and a leading teacher first-class air tickets.

After getting on the plane, Zhou Xiu found that it was a first-class cabin, and the independent seats were very private and comfortable. Immediately, he took out the book from his schoolbag and raced to read it. Before the plane took off, Xi Shaoyuan came over and handed Zhou Xiu a glass of milk, and told her the precautions explained by Lao Wang.

Xie Cheng noticed that Zhou Xiu was reading with her head down, "Still reading?"

He lowered his head to look closer and found Zhou Xiu was watching "The Lancet". He smiled, "Is Xiuxiu's English so good now?"

The Lancet was recommended by Dr. Liu. He found that Zhou Xiu was thirsty for knowledge, so he gave her the journals he had saved throughout the year. In addition to "The Lancet", Zhou Xiu is also reading other journals about tumors. Although it is ridiculous, she is really trying to understand Zhou Cheng's disease.

It took Zhou Xiu a long time to respond to Xie Cheng's question. She shook her phone and smoothly opened Google Translate to show him.

Xie Cheng laughed dumbfounded.

He watched Zhou Xiu quietly. He knew what happened to Zhou Xiu's father. He only saw Zhou Xiu lose her composure that day. Self-regulation is accomplished, and he admires her wholeheartedly.

Xi Shaoyuan watched Zhou Xiu drink the milk before leaving.

The first-class stewardesses liked to serve these three young and beautiful children. They asked Xi Shaoyuan and Xie Cheng if they wanted blankets, and changed Zhou Xiu’s water-based pen to a pencil. They made three trips just for food and drinks. If Zhou Xiu hadn't frowned to signal the need to read quietly, they might not be able to stop their enthusiasm.

Flight attendants rarely see such good-looking children. The appearance of the three students is rare, especially the two boys. They are like natural clothes hangers, with broad shoulders and narrow waist, and slender and straight legs. There was a breath of youthful vitality in the face.

It is worth noting that at the same time, there was a fresh meat in the first class cabin. The stewardesses couldn't help but sigh in their hearts. Compared with these two teenagers, the little fresh meat who left the refined picture was too far behind.

After arriving in City B, Jiang Jiajun's text messages rushed out, inviting Zhou Xiu to his home for dinner. Zhou Xiu thought about the relationship between Jiang Jiajun and Jiang Huai, pondered for a moment, and replied, "Thank you, no need."

There are 8 students from No. 4 Middle School entering the provincial team. The students of No. 4 Middle School heard that Yude came here by first class, and they couldn't help being envious. Lu Liu put his arms around his shoulders and joked, "I know why Xu Xu and Xie Cheng went to Yude."

At this time, the advantages of key private high schools are highlighted, and this kind of local tyrant behavior is absolutely unfeasible in public high schools.

The teacher of No. 4 Middle School felt a heart attack at the envious eyes cast by the students. He said to his students with a straight face and seriousness: "Everyone is tired today, let's all go back and rest!"

In private, he despises the deeds of a nouveau riche like Yude. If he has such leisure time, he might as well think about how to improve students' grades.

That night, students from various provincial teams gathered to report on the spot.

Lao Wang called out the three students who were most keen-minded, and said with a smile: "Xie Cheng, Xi Shaoyuan, Zhou Xiu, you should rest well these two days, recharge your energy, and take the exam the day after tomorrow. Especially Zhou Xiu, I found you If you write questions in the middle of the night, you will be fined to write ten sets of questions when you go back."

He said to Xie Cheng earnestly: "This is your second time participating in the national competition. Don't hand in the papers before you finish the exam like last time."

Xie Cheng participated in the winter camp last year and ran back without saying hello. Lao Wang heard that he handed in the papers in advance, half an hour early, and finally missed the national training team by 3 points.

Others didn't have enough time to write the test papers, so he handed them in early! Pharaoh's heart was stuck for a whole year last year, and his heart bleeds whenever he thinks about it.

He looked at the three students and said in a gentle and encouraging tone, "The principal said that this time Yude will win a gold medal no matter what. I believe you. You are all excellent children. I have brought you The strongest class of students."

At the end, Lao Wang gently told Zhou Xiu to eat well.

"It seems to be thinner, I have worked too hard during this time!"

Even Old Wang, who is like a straight man of steel, noticed that Zhou Xiu had lost weight, which shows that she has indeed lost too much weight during this period of time.

In the evening, instead of writing the test paper as usual, Zhou Xiu called Liu Mei.

She chatted with Liu Mei lightly, with a smile on her lips, and a pair of eyes on her peaceful face revealed a deep tenderness. On the phone, Liu Mei told her to take the exam well, and Zhou Xiu nodded in agreement.

The meaning of the gold medal at this time is not only an honor for Zhou Xiu, but also Zhou Cheng's hope. For today, Zhou Xiu has seriously prepared for the whole year.

Many fans in Zhou Xiu's live broadcast room know that she has entered the finals. Even if she is not on the air tonight, there are occasional encouraging barrages floating by.

"Anchor, come on for the national competition!"

"The anchor is a person with ideals. The happiest thing in the world is to strive for ideals."

"I'm on the same field as you, let me do my best too. I've been looking forward to today for a long time."

Zhou Xiu opened it and looked at it for a while, her heart was warm, she was filled with these words of encouragement, and she was full of strength.

She fell asleep very early that day. In her dream, she saw her father's bright smile like the sun, his figure busy around the stove, and the green smoke and the smell of rice curling up from the woodshed.

He carried her around at other people's banquets, Zhou Xiu scraped the fish scales, and Zhou Cheng made it into a delicacy with a smile. He gave her the money he earned to pay her tuition and buy delicious food...

The next day was the opening ceremony of the winter camp. This year's opening ceremony invited important figures from all walks of life, including the director of the Education Department of City B, the secretary-general of the municipal government, the vice president of Tsinghua University, the chairman of the Mathematics Society, and the vice chairman of the National Association for Science and Technology... The concluding speech was an expert in mathematics Very prestigious academician of the Chinese Academy of Sciences.

Academician Tian said: "Mathematics is the foundation of all natural sciences. Every great change in human society is supported by mathematics. To realize national rejuvenation and stand in the world's strong forest, we must have a deep and firm grasp of mathematics. This key. May all young people study mathematics hard, take over the burden of building socialism from the pioneers of the previous generation, and strive for the rise of China.②”

There was warm applause at the scene, which lasted for a long time.

Zhou Xiu was silent in her heart. Behind every advancement in medical technology is indeed mathematics. Recently, she read medical books, and she has such an experience.

For example, BNCT technology has appeared in the last century, but its nuclear neutrons need to be produced by nuclear reactors, and a series of expensive costs such as high radiation, nuclear safety, nuclear storage, etc. have slowed down the progress of this technology. These problems were not resolved until the development of electron linac-driven optical neutron source devices.

After the opening ceremony, the exam kicked off.

On the first day of the exam, Zhou Xiu went through the three big questions. The first question was listed quite well, and it took Zhou Xiu less than 20 minutes to solve the difficult question for the college entrance examination. The students in the examination room were in good condition and finished the first question with a smile.

The second question was number theory, and the difficulty rose sharply. However, she had carefully studied number theory and advanced algebra for a period of time when she was a sophomore in high school, so it didn't take time to write it. After Zhou Xiu finished writing, she subconsciously looked at the time, it was still early, so don't worry.

Zhou Xiu was stuck on the third question for a long time. She stared at the question and thought about it for half an hour. It is still a number theory problem, very cumbersome. Zhou Xiu had already brushed up all kinds of question types before, but she was stuck by it, she was still too young and energetic...

Half an hour later, Zhou Xiu used the principle of tolerance and exclusion to find a way to solve the problem, and it took two hours to complete the verification. The process was cumbersome and extremely exhausting. This question may be extracted from a professor's paper. It is a test of skill but has no practical significance. The time came to 11:03, about an hour and a half before the end of the exam. The gold medal is of great significance, Zhou Xiu didn't dare to be careless, and went back to check it carefully, and it took another hour.

At 12:10 in the morning, Zhou Xiu sorted out the test papers and draft paper and handed them in.

Everyone looked at the thin and neat figure, who walked out of the examination room without looking back, holding a simple transparent pencil case.

Zhou Xiu didn't know how much pressure he put on the students in the same examination room when he walked out of the examination room. The test papers she handed in were densely written, and the hearts of all the students in the examination room sank like lead. When Zhou Xiu left, most of the students in the examination room were still stuck on the second question, and the draft paper on the table was getting thicker and thicker. Some people spent ten draft papers without solving the second question.

The second day's exam was more difficult than the first day. Zhou Xiu didn't even have time to look at the time. He was mentally and violently calculating the questions. The draft paper was used up quickly. In the cold winter, Zhou Xiu's forehead was gradually sweating. beads.

When she wrote the last sentence "There is f(x)=x", she finally breathed a sigh of relief.

After the exam, many people can't help but sigh: the competition career is over. Some people lamented that they had to take the college entrance examination when they went back...

Lao Wang was waiting for the students in the Buddhist department of the hotel. On the one hand, he was waiting for the end of the winter camp and the official announcement of the results. On the other hand, he was actively contacting the team leader. When he saw Zhou Xiu running out, he felt a lot of pressure.

"Why did you come out so early and didn't even attend the award ceremony?"

The education of No. 4 Middle School is famous all over the country. The teachers of No. 4 Middle School are not worried about winning the gold medal. What they care about is whether the students can enter the national training team. Lao Wang has led many mathematics competitions. Except for Xie Cheng who won a gold medal last year, there are very few gold medals in his teaching career. I finally came across a few good seedlings, and it took a lot of hard work to guide them.

Lao Wang expressed great expectations for this year's competition.

Zhou Xiu ran out in a hurry, "I've already told the team leader, it's too late, I'll go to the airport first."

Old Wang was very upset, Xie Cheng was like this, even the most reliable Zhou Xiu was like this, his heart was twisted into powder. But he fixed his eyes and saw that the student's eyes were red with tears in his eyes, and he was already trying to control his emotions while talking to him. Old Wang was shocked.

The reprimand on his lips suddenly turned into an unconditional tolerance. He took Zhou Xiu's luggage and said seriously:

"Hurry up, Zhou Xiu, I'll see you off."

Lao Wang was using his mobile phone to check back the earliest plane in City C, and the tickets were sold out as soon as he refreshed. At this moment, a black Bentley stopped at the entrance of the hotel. Xi Shaoyuan called Zhou Xiu to say that he had bought a ticket and let them board the car.

After Zhou Xiu arrived at the airport, he persuaded Lao Wang to go back.

"Mr. Wang, I can go back by myself. Thank you for sending me to the airport."

Lao Wang was a little embarrassed. He didn't know what happened at Zhou Xiu's house, but he suddenly thought that the students had taken a leave of absence before the game, and he was very worried.

Zhou Xiu was the most self-disciplined and sensible student he had ever met, with a stable mood, and he rarely saw Zhou Xiu lose her composure. Now the corners of Zhou Xiu's eyes were red, and as she spoke, tears could fall at any time.

The ticket sales for Zhou Xiu's flight had been stopped, and Lao Wang had no choice but to send her back even if he wanted to.

Zhou Xiu bid farewell to the teacher and turned to go to the security check. The sweet female voice announced the flight information. There were people coming and going in the airport, and everyone was in a hurry. The moment she turned her head, she saw Xi Shaoyuan's figure in the crowd.

He was wearing a long white down jacket and looked at her from a distance with calm eyes.

Xi Shaoyuan walked towards Zhou Xiu, "You don't need to queue up, it's faster to go through the VIP channel."

After the plane took off, Xi Shaoyuan handed Zhou Xiu a pack of napkins, and said flatly, "Don't worry, wipe it off."

Zhou Xiu asked Xi Shaoyuan why he was here. But Xi Shaoyuan asked: "Did you do well in the exam? People in your exam room said that you handed in the papers ahead of time. I asked Xie Cheng to stay and help us receive the medals."

After a while, he didn't hear Zhou Xiu's answer, so he took out a handkerchief and put it in her palm, "Listen... Zhou Xiu, you can cry if you want."

With that, he turned and returned to his seat.

The privacy of the single seat in the first-class cabin is very good. Zhou Xiu was in a daze with a handkerchief, as if she hadn't recovered from it yet.

Severe angina pectoris hit like a tsunami, why... like this

After the exam, everyone gathered together to exchange their feelings after the exam, and went to have dinner together. The atmosphere was rare and relaxed and happy, and the air seemed to be full of sweetness.

Zhou Xiu got the phone, turned it on, and found more than a dozen missed calls, mainly from Liu Mei, with two missed calls from Dr. Liu scattered here and there.

She dialed Dr. Liu's number, and Dr. Liu's calm voice came from the phone: "Zhou Xiu, are you still in City B? Come back."

Zhou Xiu's joy of just finishing the exam disappeared, and she had a bad premonition. Sure enough, she called Liu Mei, and Liu Mei choked on the phone and said, "Xiu'er, your father is dying... come back and see him one last time."

After getting off the plane, Zhou Xiu's cell phone kept ringing.

Xi Shaoyuan urged the driver to drive as fast as possible, and Zhou Xiu saw Zhou Cheng with tubes all over his body in the video call.

Seeing his weak and haggard appearance clearly, her heart ached so hard that she couldn't breathe.

Zhou Cheng, who has undergone chemotherapy, actually doesn't have a good appetite, but every time he finishes eating Zhou Xiu's meals with a smile, it looks like it tastes delicious. But after Zhou Xiu left, he would vomit up and down, and then Liu Mei would feed him some porridge and sugar water.

In order not to worry Zhou Xiu, every time she comes to the hospital, he always puts up his energy and pretends to be in good condition. In the middle of the night, he tossed and turned in pain, unable to sleep, and wet his entire vest. In mid-November, Zhou Cheng no longer had the energy to "act", and politely advised Zhou Xiu not to come to the hospital.

Zhou Xiu got out of the car and ran to Zhou Cheng's ward with all her might.

Dr. Liu finally saw the two children who were besieged by travel and dust. He said to Xi Shaoyuan regretfully, "I tried my best, but he discovered this disease too late. If it was half a year earlier—"

He said shaking his head. Xi Shaoyuan couldn't say anything more, just nodded to him, "Thank you."

Zhou Xiu saw Liu Mei lying collapsed beside Zhou Cheng's bed and crying bitterly. The tube was removed from his body, but he didn't respond at all, and he couldn't even breathe.

Zhou Xiu tasted the feeling of a thousand arrows piercing the heart. She lifted the white cloth and saw her father's swollen belly, his thin face, and his thin cheekbones with years of sunburn.

She couldn't believe it, Zhou Cheng was still there on the way here, he was still there - his stomach was still breathing, heaving, and his eyes could be opened.

Zhou Xiu asked the system countless times in his heart, why is this happening

If there is still no way to change the ending after doing it all over again, what is the point of doing it all over again

She thought that as long as she worked hard enough, Zhou Cheng's ending would be different. Their family would live happily ever after, and he would witness every important moment in her life with Liu Mei. After a hundred years, she could live happily. Send Zhou Cheng the end.

She will use her grades to tell the world that although she is not a boy, she is more promising than a boy. She will become Zhou Cheng's pride and make him the envy of everyone in the village.

But—now all these good things have been shattered! All of this is just Zhou Xiu's fantasy!

Liu Mei raised her head and noticed something was wrong with Zhou Xiu. She was trembling all over, her face gradually turned livid, and she even had difficulty breathing. She quickly patted her daughter on the back, tears streaming down her face, "Xiu'er, don't scare mom—"

She didn't want Zhou Xiu to see Zhou Cheng's appearance like this. The appearance of a patient with advanced cancer is more scary. Many places on his body are swollen and sore.

She found an excuse to send her daughter out, and she wanted to send Zhou Cheng off for the last time by herself.

"Mom hasn't eaten all day today, can Xiu'er buy me something to eat? I didn't eat dinner yesterday... Shaoyuan, help me see Xiu'er."

Zhou Xiu was driven out of the hospital by Liu Mei in despair. She tried her best to maintain her emotions, knowing that she would hurt her body if she continued like this. Liu Mei was sad enough, she must not make Liu Mei sad again.

The weather in City B today is rare and clear, without smog, and the sunshine like broken mercury dazzles people's eyes. But it was raining in city C, just like the day she resolutely came from the mountains to the big city and was thrown into a drenched chicken. She was so full of hope then that the rain felt warm even when it was cold. Now Zhou Xiu was wearing a down jacket and holding an umbrella, but she was shivering from the cold.

The restaurant across the road played pop music, and the rustling rain wafted hoarse and affectionate songs.

"I always ask you for money, but I never say thank you. I didn't realize that it was not easy for you until I grew up."

"Every time I leave, I always pretend to be relaxed. I smiled and said go back, and turned around with tears in my eyes."

As soon as Zhou Xiu heard the prelude, tears flowed down as if his lacrimal gland had been poked.

When I was young, my younger siblings always had new clothes to wear, but Zhou Xiu didn't. She complained about Zhou Cheng for a long time, and when Zhou Cheng found out, he went around the village begging others to find him odd jobs. He always asked her with a smile: "Xiu'er, look what Dad bought for you?"

Then he conjured up books and new clothes he bought from the county.

"How much I want to be the same as before, holding your warm palm. But you are not by my side, and I entrust the breeze to take you to Ankang."

At this moment, Zhou Xiu really wanted to shake his callused hand and see him for the last time.

She didn't know that Zhou Cheng was already so sick. If she had known this, she would rather not join the CMO, but stay with him to spend the last period of time. He always proudly introduces to others that she is good at reading, he wants to attend another parent meeting, see her take the college entrance examination with his own eyes, and see *** Square with his own eyes, but he can't understand such a simple thing. not done…

The male voice in the song is always full of regret, and it becomes an intensified cry, "Slow down time, don't let you grow old again."

"I am willing to use everything I have in exchange for your longevity."

"Thank you for everything you do, supporting our home with both hands. Always try your best to give me the best. ④"

Zhou Xiu knelt down and held her head, tears streaming down her face uncontrollably.

Why did someone like her have a chance to start over, but Zhou Cheng didn't? She is arrogant and self-righteous, while Zhou Cheng is kind and diligent. He has never done a single bad thing in his life, but he has suffered a lot. If possible, Zhou Xiu would rather give up this opportunity to Zhou Cheng.

Xi Shaoyuan chased him out, and he saw Zhou Xiu suddenly squat down, hugging her knees on the side of the road and crying out of collapse. The pouring rain soon wet her hair, and the rain meandered down the corner of her clothes, her pitiful and helpless appearance was the same as when they first met.

Xi Shaoyuan held an umbrella to shield her from the rain. He squatted down and stared into Zhou Xiu's eyes, and said calmly, "Zhou Xiu, be strong."

"I know you're in pain, but uncle definitely doesn't want to see you like this."

He ran to the opposite restaurant and replaced the song that made Zhou Xiu cry.

Xi Shaoyuan knelt down and said to Zhou Xiu seriously: "Everyone's life is always full of parting and regrets. Human beings are born lonely. In fact, parents, lovers, friends, and relatives can't accompany us through the whole life. All we can do is stay together. Cherish the time and don’t regret leaving.”

"I heard from Dr. Liu that my uncle has watched your competition video several times during this time, and slept with your medal at night. He is very happy to have such an excellent daughter like you. Xiuxiu, don't blame yourself, you have already done it Very good."

Zhou Xiu's tears fell more violently, mixed with the rain, it was impossible to distinguish where was rain and where was tears.

Xi Shaoyuan said: "Let's go back and see him off for the last time."

After a long time, Zhou Xiu cried so weakly that she figured it out and stood up and went back to the hospital. She wants to see Zhou Cheng off for the last time.

Hot tears fell on Xi Shaoyuan's hands, he wiped them with a paper towel, and wiped off the water droplets on Zhou Xiu's body by the way, and went back to the hospital with her.

A staff member of the organ donation center in the hospital asked Liu Mei if she would like to donate Zhou Cheng's body for medical research. At the same time, the staff of the funeral home contacted her to ask about Zhou Cheng's cremation and what happened after his death.

Liu Mei tremblingly said that she would donate her husband's body, and she signed her name tightly while holding the pen.

Zhou Xiu still couldn't figure out why the system had to find her a year ago.

If nothing can be changed, what's the point of doing it all over again

Last year, the school organized a physical examination for all students. After Zhou Xiu finished the physical examination, he asked his parents to do it too. Zhou Cheng smiled and refused at the time, because he was busy, because business could not do without people, and on the other hand, he was not willing to spend money on it. Would the results be different if I had a physical exam

Zhou Xiu has never hated poverty so deeply. If they had enough money and time, everything would be different today. If she didn't need to be busy making money, she wouldn't leave Zhou Cheng. If they stayed in the small village, Zhou Cheng wouldn't be so tired, and she could spend the year with him well.

But there were no ifs in her life. Until the last period of his life, Zhou Xiu was still busy with writing questions and studying.

Zhou Xiu covered her face and cried bitterly. At this moment, the system sighed and said, "Xiuxiu, your idea is actually wrong. Everyone is equal before life. The poor will get sick, and the rich will get sick too. If you don't believe me, look at you on the left hand side."

Zhou Xiu had tears in her eyes, and through her blurred vision, she saw a six-year-old child.

The child murmured with tears all over his face: "Doctor Liu, will Mom never come back again?"

"I really hope... my mother can have a panacea like in the cartoon, and she can be lively after eating, and she can play with me as before."

The childish words made the parting even more sad, and his father burst into tears and silently patted the back of his head.

Zhou Xiu recognized the child, it was Aunt Li's child in the intensive care unit upstairs. It was from a very wealthy family, and her father was the president of a listed company. She vaguely remembered that she drove a luxury car to the hospital on the day she was admitted to the hospital, but she didn't expect him to be gone in just one month.

Aunt Li's family bowed deeply to Dr. Liu, "Thank you, thank you Dr. Liu for allowing her to live a good month."

They shook hands with doctors and nurses tightly.

The system slowly said: "Look, there is no difference between rich and poor in the face of diseases. The fundamental reason why people are vulnerable to diseases is the backwardness of science and technology. Thousands of years later, the earth will have no cancer and no genetic diseases. Human beings have solved the five major medical problems of cancer, AIDS, leukemia, ALS and rheumatoid."

It showed Zhou Xiu a different life, and a roll of colorful pictures appeared in front of Zhou Xiu.

Human beings in the future will live a long life. There will be no cancer, no AIDS, no leukemia...everyone will be healthy and happy.

At the end of the image is a girl's life.

She grew up in Dashan, and walked out of Dashan with the help of a kind-hearted person. Her grades were excellent, and she went to Harvard to study after graduating from high school. Three years later, her father passed away, and she was determined to engage in the research of overcoming cancer in grief. The G-Mendelian laboratory established by the Wuhan Institute of Biology in China is dedicated to solving human genetic problems.

After decades of struggle and research, her team discovered that cancer lesions can be interfered with by removing tumor stem cells, and the history of human cancer has turned around: cancer can be completely cured. For this reason, she and the whole team worked hard and studied hard. Before her death, the therapy and medical equipment used to treat cancer had been promoted, and the cancer cure rate reached 99%.

Outside the ward, Zhou Xiu stared obsessively at the wonderful picture in front of him, and couldn't help murmuring enviously: "That's great..."

At the same time, the hot tears in the eyes slowly flowed down the face.

This is Zhou Xiu's life.

Zhou Xiu couldn't believe that this was something she could do. It would be great if Zhou Cheng could use this kind of achievement. He could watch her pass the college entrance examination with his own eyes, and the whole family went to *** to watch the flag-raising ceremony together, and enjoy her old age peacefully.

The system seriously took off its hat to Zhou Xiu, stood at attention and saluted, "Please allow me to introduce myself. I am Simon, captain of the machine 2876 regiment. Hi, doctor.zhou."

"Unfortunately, Zhou Xiu like this only appeared once in history, and a small mistake changed the track of history. Once you died because of being abandoned in childhood, because you dropped out of school and missed science, and because you worked to earn money, you died unexpectedly early. Depressed by the death of my father…”

It was not until 5,000 years later that a letter left by the human scientist Einstein to the future was fully published. Einstein wrote in the letter, "Our era is full of creative inventions, which greatly facilitate our lives."

"Compared with those who really contribute to society, the general public has a much lower level of intelligence and moral character.③"

"In the era I live in, society is full of wars, aggression, and fear strikes everyone's heart. Scientists perish in the process of fleeing, like meteors flashing in the sky. There are many admirable and admirable people among them , if they can survive and give full play to their strengths, today's society will not be what it is now... "

He proposed a protection plan for human scientists, trying to use quantum cryptography as a communication link between future humans and modern humans. At the beginning of the 21st century, the highest secrecy department of the United Nations secretly established the P·S Center, and the funds were maintained by financial allocations from various countries. Until 2020, it received the first quantum radio code from the robot Simon 5,000 years later.

This part was specially encrypted by the United Nations at that time, and it was called the P·S plan in history, where P stands for portect and S stands for scientist.

Zhou Xiu is a member of the P·S project list. Because of her untimely death, the eradication of cancer has been postponed for three hundred years. During these hundreds of years, many outstanding scientists died of cancer, like brilliant meteors flashing across the sky.

Zhou Xiu wiped her tear-soaked face, and murmured: "I understand, but Zhou Xiu is Zhou Xiu, and I don't need to be saved. 'She' works so hard, the one who wants to save most in her heart is Dad."

The person who needs to be saved most is Zhou Cheng, and the system should be placed on Zhou Cheng.

The system said with regret: "Uncle's life span is destined to be only 40 years, and it cannot be changed. The food he eats, breathes and excretes, travels, consumes daily necessities, and even every tiny behavior of him will affect the future. Make an immeasurable difference."

A chicken that Zhou Cheng ate 5,000 years ago, if it had not been eaten by Zhou Cheng, it would reproduce at least 5 chicks in its lifetime, and the chicks would give birth to chicks, with endless descendants. The disappearance of a chicken now will lead to the disappearance of several large chicken farms in 5000 years.

It smiled affirmatively at Zhou Xiu: "But what is pleasing is that future human beings are willing to bear the impact of his extended life, because of his daughter—"

The light screen in front of Zhou Xiu showed the scene of everyone signing the treaty 5,000 years later. Creatures of different skin colors and races in the future gathered together to solemnly swear an oath.

"I am willing to be a vegetarian for Grandma Zhou's father for ten years."

"I am willing to reduce travel and save paper and electricity for Professor Zhou."

"I am willing to give one day of my life to Father Zhou."

"I am willing to reduce the cost of wind, electricity, light, food and all energy sources."

The system smiled and said: "Xiuxiu, now please accept the gift from the future."

With a ticking sound, Zhou Xiu's tears splashed from her cheeks to the ground. From this moment on, the ward in front of Zhou Xiu changed: the flow of people receded like rewinding, and on the clock dial hanging on the wall, the second hand rapidly rotated counterclockwise round after round, and the time slowly moved from 18:49:01 to 17:29:13 Backflow.

The font on the body donation letter signed by Liu Mei disappeared stroke by stroke.

The kid who dragged his father to ask if there was a panacea that could be given to his mother, tears back, and slowly retreated from the 4th floor to the intensive care unit on the 5th floor. Zhou Xiu seemed to be standing in the vortex of time, feeling the force of the lost life being loaded back.

That was Zhou Cheng's kind taste.

The nurse reinserted the unplugged cannula back into Zhou Cheng's body, and finally time flowed back to the moment of 16:49:50. Life was fully infused into Zhou Cheng's body by time in a domineering way, and the connected electrocardiogram went from still to 16:49:50. The straight line suddenly turned into a sawtooth wave.

Zhou Cheng's slumped hand slowly lifted up, and his closed eyes reopened.

The flow of time finally returned to normal, and Liu Mei cried loudly beside Zhou Cheng's bed, "Xiuxiu will be back soon, can you wait for her for a while!"

"Don't you want to see her for the last time?"

Zhou Cheng coughed, took off the oxygen mask and the tube on his body with difficulty, and sat up straight, "Say... what are you talking about, I'm fine. Isn't Xiu'er taking an exam, why did you call her back? "

Zhou Cheng patted his ascites-filled stomach. Normally, he was in so much pain that he wanted to die. Unexpectedly, all the pain disappeared now. He felt unprecedented relief, which was incredible. He even thought he was dead, otherwise how could it not hurt at all

He said cheerfully, "I'm fine, I don't hurt anymore, really."

Liu Mei watched in horror as Zhou Cheng actually sat up, as if he was returning to the light. She checked him inside and out, asking him what was wrong.

Then, Zhou Xiu was dragged by time back to the car that was rushing from the airport to the hospital. Xi Shaoyuan urged the driver to drive faster while comforting him: "Don't worry, we will definitely make it."

In the dim view of the car, the video call on the mobile phone was dropped and connected, and Zhou Xiu suddenly shed tears watching the two people in the video.

She saw Zhou Cheng scolding Liu Mei for making a fuss in the video, she turned to her and said, "Xiu'er, Dad is fine. Oh, you came back so early, have you finished the exam?"

The corners of her mouth were gradually pursed, and she answered Xi Shaoyuan with tears and a smile, "Well, I will definitely be able to catch up this time."

The windshield wipers of the car kept swinging back and forth. At this moment, the silence inside the car was in stark contrast to the noise of the pouring rain outside, as if they were in two worlds. When the lights came on, the car flew past the city, and the phantoms of the neon lights were reflected in Zhou Xiu's black eyes.

The future is waving to her, and her heart is filled with warmth.
