More and more students asked questions. Pei Zhi returned to the blackboard and wiped it off after writing. The chalk dust fell down like snow particles.
When it was Lin Zhaoxi's turn, she was no longer as nervous as when she came.
Under Pei Zhiping's peaceful gaze, she briefly explained the purpose of her visit.
"What's the question?" Pei Zhi asked.
Another heartbeat missed, Lin Zhaoxi wanted to rub her ears, why was the voice so pleasant.
Holding back her excitement, she took out the question paper from her pocket and handed it over.
Pei Zhijin pressed his strong fingers on the paper, glanced at it, put down the paper, took a half step back towards her, pinched the white chalk with three fingers, and with a questioning look, wrote a number on the blackboard—16
What is done in three seconds and five seconds, it's not even half a second.
Lin Zhaoxi was dumbfounded, but Pei Zhi still kept his questioning gaze. Only then did she realize that Pei Zhi was asking her if the answer was correct, so she nodded quickly.
Seeing this, Pei Zhi put his palms on the blackboard, erased the answers casually, and answered seriously: "For those who have studied mathematics for a long time, this question is not difficult, but it tests thinking and analytical ability. Come on, it's fun."
"So, is it appropriate?"
Pei Zhi nodded.
Lin Zhaoxi was very happy. Although the answer was short, it was obvious after thinking that Pei Zhi was a very serious person.
As the wind came slowly, she thanked Pei Zhi, pinned her disheveled hair behind her ears, turned around and left without any reason to hold back.
People from the student unions of each school are behind the lecture theater.
Lin Zhaoxi went over and was surrounded to ask the result.
She repeated what she had said.
Someone responded quickly: "What Pei Zhigang wrote on the blackboard is the answer?"
"yes."
"not human!"
Lin Zhaoxi agreed.
They chatted at the back door for a while, and basically decided on the topic of the quiz.
Lin Zhaoxi took the opportunity to see Pei Zhi more.
Look at Pei Zhi's meticulous and focused expression, look at Pei Zhi's wrists when he writes, look at the starry eyes of the girls looking at him, look at her very powerful classmate...
But after watching for a long time, Lin Zhaoxi gradually realized that Pei Zhi and she were not from the same world.
Although from the beginning to the end, Pei Zhi was always calm and polite, never condescending. But her girlish heart, which was full before she came, became empty.
She suddenly glimpsed the unreachable gap between him and Pei. The gap comes from one party's ten years of concentration and accumulation, and the other party's ten years of eating and waiting for death.
Not to be ashamed, but very disappointing.
The red clouds in the sky dimmed, and the people queuing up to ask questions in the classroom were almost dispersed.
Pei Zhi picked up the coat that was draped over the corner of the podium and began to pack his things.
"Shall we go too?" Su Xiaoming said.
Lin Zhaoxi nodded, she and Pei Zhi had also talked, and stared at him for so long, there really was no reason to stay any longer.
It's like fulfilling a wish.
She looked at the concrete floor in front of her and moved her steps, but her mind was full of pictures of girls in animation—she suddenly turned around and shouted, "Student Pei Zhi, I have liked you for ten years"!
But she didn't do it because she didn't have the courage.
More and more people are leaving together, both by the back door and by the front door.
The fabrics rub against each other, very realistically.
Suddenly, a bright voice sounded: "Senior Brother Pei Zhi, can we... can I ask you a... more personal question?"
Lin Zhaoxi stopped as if saved, and followed the sound.
Pei Zhi was very frank: "Yes, but I have the right to refuse to answer questions that are too personal."
With one hand in his pocket, he held the examination paper and manuscript paper in the other hand. The paper drooped and moved with the wind.
"Are you leaving?" the elementary school girl asked, "I mean...studying abroad?"
Hearing this, the girls in the lecture theater all let out a "hey" one after another, one was accidental, and the other was that they thought it was a great opportunity and they should obviously gossip about it.
"Yes." Pei Zhi replied very simply.
"which school?"
"CHU."
Lin Zhaoxi's heart skipped a beat. If it wasn't for her, Lao Lin would almost have gone to this school. What a coincidence.
The disappointed sighs of the girls echoed. They probably couldn't explain why, but they just felt very sorry.
So someone asked: "Brother, will you come to school again in the future?"
"Why not?"
"But you seldom come here recently."
"There will be less in the future."
"..."
"So this year's Mathematical Modeling Contest will still be led by you?"
"yes."
"Can we sign up?"
"Yes." Pei Zhi added patiently, "The school's official website has detailed rules for registration and selection of players. If you are interested, you can check it out."
A good "ask a personal question" activity turned into a consultation meeting in an instant, and the students chattered.
"We watched!"
"But it's too perverted!"
"Brother, don't we, there are no detailed rules, just one question!"
"Any questions?"
After Pei Zhi asked, he unexpectedly walked to the blackboard, picked up half of the chalk, and quickly wrote the topic in the middle of the blackboard.
He wrote very freely, but Lin Zhaoxi unexpectedly felt that Pei Zhi was very gentle at this time.
"We can't do it!"
"This is too difficult!"
Before he finished writing the question, the howls gradually sounded from below.
But for Lin Zhaoxi, when Pei Zhi began to write the first stroke, she could no longer hear the surrounding voices. Even Pei Zhi's figure disappeared from her sight, and she could only see the slowly forming question.
It was long and difficult, and she could understand some parts, while others were completely foreign to her.
She was completely immersed in it, feeling puzzled but also found it very challenging. She subconsciously flipped through the materials in her hand, took out a pen from her pocket, and copied them down.
While writing, some strange ideas continued to pop up in her mind, and she couldn't help but record them all.
"Hey, Lin, are you solving problems?"
Suddenly, someone shouted beside Lin Zhaoxi, and she was startled suddenly.
An Xiaoxiao's voice was very loud, and in an instant, the eyes of the entire classroom were focused.
Pei Zhi had already reached the door, stopped and looked at her.
Lin Zhaoxi's first reaction was embarrassment, what is she doing
Girls from the Department of Philosophy are trying to solve a problem posed by a male god on campus in the classroom of the Department of Mathematics. The picture is too overwhelming and sour.
She looked at Pei Zhi cowardly.
Pei Zhi's eyes were still sober and clear.
There are always some people who make you want to be that kind of person just by looking at him.
Lin Zhaoxi quickly calmed down, what is there to be afraid of
"I'll copy the title." She said to An Xiaoxiao.
"Senior sister really wants to join Pei Zhi's team?" An Xiaoxiao glanced at the male god comrade at the door, "No wonder senior sister took the initiative to ask Pei Zhi a question just now..."
"Study hard and ask questions."
"No, no, I don't think so. Doesn't senior sister study philosophy?" An Xiaoxiao paused for a moment, then raised the corners of her mouth, "You work so hard to do math problems, so you must be secretly in love with Pei Zhi, right?"
When it comes to this, it is no longer insane. The surrounding classmates looked at her with sympathy.
Lin Zhaoxi really didn't care about An Xiaoxiao's run-off, but at that moment, in that situation. In the distance was Pei Zhi's handsome figure, dimly lit by the setting sun.
She suddenly smiled, turned to look at An Xiaoxiao, and asked, "Hey, how do you know?"
Silence, at first it was quite unbearable silence. The students looked at each other in blank dismay. They didn't expect to hear the explosive confession in the last class. Then, who knows who "puchi" laughed out loud, and then the whole classroom erupted in laughter.
An Xiaoxiao was very proud at first, but gradually, she found that the students around her were not mocking anyone. The students were very happy, some applauded and some even whistled.
Lin Zhaoxi was frank and frank, and laughed.
At this moment, Pei Zhi moved. With one hand in his pocket and his coat casually on his hand, he walked up the stairs from the lecture hall and soon stood in front of them.
The whole classroom was silent again.
Lin Zhaoxi was shocked when she saw Pei Zhi's handsome face, what do you mean
Pei Zhi himself didn't think there was any problem with doing so, so he asked casually, "Are you explaining?"
"Just... write down your thoughts?"
Someone in the classroom gasped.
Only then did Lin Zhaoxi realize that she was too immodest to answer like this, so she quickly changed her words, "I just copied the topic and went back to study it."
"Can I have a look?" Pei Zhi said.
Lin Zhaoxi's heart beat uncontrollably again, but Pei Zhi's eyes were still clear and natural, as if she didn't care about her public confession just now. But yes, it sounds like a joke, how could the male god care.
She was even more relieved, dropped all the white papers in her hand, and handed them over.
Pei Zhi took it with his slender fingers, and she could clearly see the small shadow covered by his eyelashes. In the next second, Pei Zhi actually carefully read the problem-solving ideas she wrote down.
Soon, Pei Zhi raised his head and asked her in a low voice, "Fisher's linear discriminant function?"
"ah?"
"Classification of complete solutions?"
She shook her head.
"It's already pretty good."
Pei Zhi handed back the draft paper to her, nodded at her, then put his hands back into his pockets, turned and left.
The whole process was so fast that Lin Zhaoxi didn't even understand what happened just now, but people around her were asking her.
"Senior sister is so strong, the male god said you are very good, can I see your thinking?"
"What did Pei Zhigang tell you?"
"Is senior sister really from the Department of Philosophy?"
Lin Zhaoxi could hardly hear any sounds around her. She withdrew her gaze from looking at Pei Zhi's back, and looked at the draft paper in her hand again.
After calming down, she was sure that it was a pity that she really saw the fleeting look in Pei Zhi's eyes just now. Whether it is "function" or "category", it is even possible that Pei Zhi is inspiring her. But she couldn't even repeat the nouns that Pei Zhigang said.
Already... very good...
Not bad, just for a philosophy student.
Lin Zhaoxi suddenly felt sad, because at that moment she clearly realized that the distance between her and this topic was equal to the distance between her and Pei Zhi.
In other words, it seems to be close at hand, but in fact it is far away.
She couldn't stay any longer. Passed the manuscript paper in her hand to the boy who wanted to see it, and said hello to Su Xiaoming, she left the back door and walked in another direction with the flow of people.
When she was almost at the end of the corridor, she took a deep breath and turned her head to take a last look at Pei Zhi.
In her sight were the gaps between people, youthful smiles and various clothes, but at that moment, what she could see most clearly were Pei Zhi's fingertips and the white chalk dust on his clothes.
The last clear light of day fell on him.
so good.
Lin Zhaoxi turned her head and looked at the distant sky.
It turns out that the plot will not change qualitatively because of the sudden pause.
They will eventually drift away as they do now, and they will never meet again in a long life.
