After the literary test is over, the military test will be held seven days later.
For five consecutive days, Li Yi never saw Li Han.
I heard from Duan Wu that he locked himself in the School of Mathematical Sciences and stayed behind closed doors for five full days.
Prove that any even number greater than two can be written as the sum of two prime numbers.
This question seems to be only a short line of words, but it has troubled the world's mathematics community for nearly three hundred years.
This is the famous world problem, Goldbach's conjecture, code-named "1+1=2".
At that time, even Euler, known as the greatest mathematician on earth, failed to prove it in the mathematics world. After that, this problem has been studied by the mathematics community for nearly three hundred years. Until the day when Li Yi went to the library to use the air conditioner, no one proved it.
If Li Han really proves this proposition, Li Yi will confess him and burn at least three incense sticks every day.
Young people are high-spirited, a little self-confidence is a good thing, but you must not be arrogant. Li Han is very smart, but he has a big shortcoming. If he has not encountered setbacks for a long time, he will drift away...
After five years, if he is not allowed to wake up properly, he will drift so far that he will not know the heights of the sky and the depth of the earth, and he will not know that there are people beyond people, and there is a sky beyond the sky, and each problem is more difficult than the other.
Duan Wu grabbed his arm and said in a low voice: "Brother, he has worked hard these few days, so don't make things difficult for him..."
Li Yi nodded and said, "Okay, okay, don't embarrass him, our little Duanwu also knows how to love others..."
Looking at Duan Wu's flushed face, Li Yi thought to himself that Li Han, this guy, has become good at routines in the past few years, and he is no longer that stupid little fat guy who only knows how to do math.
"Aunt Duanwu, I'm here to play with you."
A crisp voice rang in Li Yi's ears, and then a little girl about five or six years old, carved in pink and jade, ran in from outside.
Li Han followed behind her, his eyes were sunken, and he looked exhausted.
Li Han looked up and stammered, "Xiaorui, Xiaorui came to play with you, I, I have to watch her."
Li Yi still remembered that when they left the capital, Xiaorui, like Li Duan, walked shakyly, and when he looked at the little girl at the door again, he couldn't help but feel unreal.
In a blink of an eye, she has grown so big...
She said she was here to play with the Dragon Boat Festival, but in fact she only stood at the door for a while and then ran out.
It seems that Li Han's routine is deeper than he imagined, even such a young child is regarded as a wingman by him.
Li Han came over, pursed his lips, looked at Li Yi, and said, "Well, I can't prove that question, what should I do?"
Li Yi shook his head: "I don't know either."
Li Han stared at him with wide eyes, "No, I don't know?"
He thought he didn't know at the beginning to test him, but he didn't expect that he really didn't know.
Could it be that what he has spent the past few days sleeping all night, sleeping and forgetting to eat and sleep, is a question that has no answer
"In this world, not all problems have answers." Li Yi looked at him and said, "Don't think that after studying mathematics for a few years, you think that there are no problems in the world that you can't solve. Mathematics is far less difficult than you imagined." Simple."
What familiar words are these, what familiar scenes are these
Li Han looked at the person in front of him, and suddenly felt a little weak in his legs.
Same tone, similar words...
If it wasn't for this distant cousin from the Dragon Boat Festival, he would have never seen him at all, and he even felt that it was Mr. standing in front of him again.
He lowered his head and said tremblingly, "I, I know..."
…
"Young master, come down quickly!"
"Young master, be careful..."
"Young master, it's dangerous!"
Several maidservants of the Li family stood under the tree, raised their heads, their faces were worried, and even turned pale with fright.
"It's okay, it's not high at all." Li Duan looked down, waved his hand, threw down the Cuju on a tree branch, and said, "Go and play, if you kick it on the tree again, come again calls me."
He jumped down from the tree, clapped his hands, and when he turned his head, he found a little girl standing on the porch looking at him.
"Who are you? Why have I never seen you before?" It was the little girl who spoke first. When he saw Li Duan jumping down from such a high tree, he was startled at first, but then he was surprised when he saw him landed steadily. Besides, there was some envy on the little face.
Li Duan looked at her and said strangely: "I haven't seen you before."
The little girl looked at him and asked again: "Do you know martial arts?"
"Of course!" Li Duan said proudly, "My martial arts are so powerful that even adults can't beat me!"
Seeing his complacent look, the little girl curled her lips, thinking that Duan'er must be better than him. Duan'er said in a letter last time that he could jump from the ground to the wall...
However, she wasn't sure who was stronger, Duan'er or him. After thinking about it, she said, "My little aunt is amazing. You must not be able to beat my little aunt."
Li Duan looked at her and asked unconvinced: "How good is your little aunt?"
The little girl thought for a while, pointed to the roof beside her, and said, "My little aunt can fly to the roof in no time!"
Li Duan looked at the high roof, feeling a little guilty.
He can jump off the roof, but he can't jump up from below. If the little girl asks him to prove it now, he will be ashamed.
However, he didn't want to lose his momentum in front of this little girl, and said, "What's the problem? My little lady can also fly to the roof at once."
"Then my great aunt can fly up to two rooftops."
"My aunt can fly up to three."
"My dad, my dad can fly ten, one hundred!"
The little girl thought about it, daddy has a pair of big wings, can fly very high, there must be a hundred roofs, it is not a lie.
"a hundred?"
No one can brag, anyway, she was the first to brag, Li Duan thought for a while, and said: "My master can fly to the sun."
The expression on the little girl's face froze.
She couldn't think of anything higher than the sun.
Daddy said the sun is a big ball of fire, she thought for a while and asked, "Isn't it hot when your master flies to the sun?"
"Stupid!" Li Duan looked at her and said triumphantly, "Don't we fly again at night?"
The little girl frowned and said, "That's your master, not you..."
"Then you are not talking about you..." Li Duan looked at her and said, "I just need to fly higher than you. Can you fly to the tree?"
"..."
The little girl ran away angrily. This bad guy bullied her. When will Duan'er come back? When Duan'er comes back, he can protect her...
Li Duan pouted, this little girl, who likes to talk big so much at a young age, must be a good talker when she grows up.
Xiaorui is the best, Dad said, in two days, she can go to Xiaorui, I haven't seen Xiaorui for a long time, I don't know what she looks like now
He ran to the room, and after confirming again from Li Yi that he would see Xiaorui in two days, he was finally relieved.
However, I don't know if his nose is broken these days, why does he always feel that his father smells like fried rice with eggs...
…
Several days have passed for Princess Shouning's civil examination to recruit a son-in-law, and tomorrow is the martial examination.
The location of the martial arts test is in the Furong Garden.
Tomorrow morning, in addition to Princess Shouning, the Empress Dowager, Empress Dowager, Her Majesty, Empress Empress, Empress Dowager, and the Regent's eldest princess will all appear.
Of course, when the time comes, the ministers of military affairs of the DPRK and Chinese, as well as the dignitaries of Kyoto, will all come in to observe.
This is the biggest event in Kyoto at the end of the fourth year of Jingping.
In the Furong Garden, Shou Ning looked at the clothes on the bed, and said distressedly, "What should I wear tomorrow?"
Concubine Yan stood behind her, tapped her on the head lightly, and said: "After their competition is over tomorrow, you will have to play in person. You won't be able to wear these clothes."
"Ah..." Hearing this, Shou Ning threw himself on the bed again and muttered, "Wouldn't that be unbeautiful..."
"You, what don't you look good in?" Concubine Yan pinched her face, and said, "Go borrow a piece of clothing from your imperial sister. You can wear her previous exercise uniform tomorrow."
Shouning got up from the bed and said, "Oh, I can't win tomorrow anyway, why not dress nicely..."
Morning Dew Hall.
There was a plate of fried rice with eggs in front of Li Mingzhu. The catering bureau hadn't made fried rice with eggs for five years. However, these days, every time she had lunch, a plate of fried rice would be placed in front of her.
A female officer came in from the outside, bowed and said, "Your Highness, everything has been arranged."
Li Mingzhu nodded: "I see."
The female officer hesitated for a moment, then asked: "But Princess, what should be done with His Majesty and the Queen Mother tomorrow..."
"I have my own arrangements." Li Mingzhu said, picked up the spoon, and started to eat.
"Yes." The female officer nodded and stepped back slowly.
Somewhere in Kyoto, a fat man was stopped by a team of guards when he sneaked out of his house with a bulging bag on his back.
The fat man who answered the first three questions correctly was specially taken care of by his superiors so that no mistakes could be made, the guard looked at him and asked, "Mr. Peng, tomorrow is the martial arts test, where are you going? "
The burden on the fat man fell to the ground, and his face turned pale instantly.
He hugged the guard's leg and wailed, "Damn me, I'm not human, I won't sell fakes anymore, let me go, let me go..."
