The literary test is over, and the martial arts test will be held seven days later.

For five days in a row, Li Yi never saw Li Han once.

Listening to the Dragon Boat Festival, he locked himself in the academy and closed himself for seven days.

Prove that any even number greater than two can be written as the sum of two prime numbers.

This problem seems to be only a short line of words, but it has puzzled the world mathematics community for nearly 300 years.

This is the famous world puzzle, Goldbach's conjecture, codenamed "1+1=2".

At that time, even Euler, who was known as the greatest mathematician on the earth, failed to prove it, and then this problem was studied by the mathematical community for nearly three hundred years, until the day Li Yi went to the library to rub the air conditioner, no one proved it.

If Li Han really proved this proposition, Li Yi would offer him up and put on at least three sticks of incense every day.

It is a good thing for young people to be high-spirited and confident, but they must not be proud, Li Han is very smart, but he has a big shortcoming, if he has not encountered setbacks for a long time, his whole person will drift ......

After five years, if he is not allowed to be sober and sober, he will drift away from the south, south, north, west, north, earth, earth, and earth, and there are people outside the world, and one question is more difficult than the other.

Dragon Boat grabbed his arm and whispered: "Brother, he has been working hard these days, don't embarrass him......"

Li Yi nodded and said, "Okay, don't embarrass him, our family's little Dragon Boat Festival also knows that it hurts people......"

Looking at the reddened face of the Dragon Boat Festival, Li Yixin said Li Han, this guy, in the past few years, has been good at routines, and he is no longer the stupid little fat man who only knows how to do arithmetic.

"Aunt Dragon Boat Festival, I'm here to play with you."

A crisp voice sounded in Li Yi's ears, and then a little girl about five or six years old, with a pink carving, ran in from outside.

Li Han followed behind her, his eyes sunken and he looked tired.

Li Han glanced up and stammered: "Xiaorui, Xiaorui came to play with you, I, I have to look at her." ”

Li Yi still remembers that when they left Kyoto, Xiaorui, like Li Duan, walked staggeringly, and when she looked at the little girl at the door again, she couldn't help but feel a little unreal.

In the blink of an eye, she had grown so big......

said that she was here to play with the Dragon Boat Festival, but in fact, she only stood at the door for a while and ran out.

It seems that Li Han's routine is deeper than he imagined, and even such a young child has to be treated as a wingman by him.

Li Han walked over, pursed his lips, looked at Li Yi, and said, "Then, 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 that what he said at the beginning was not to test him, but he didn't expect that he really didn't know.

Could it be that what he has been sleeping at night these days, forgetting to sleep and eating, is a question that has no answer?

"In this world, not all questions have answers." Li Yi looked at him and said: "Don't think that after studying arithmetic for a few years, you feel that there is no problem in the world that you can't solve, mathematics is far from being as simple as you think." ”

How familiar is this, what a familiar scene is this?

Li Han looked at the person in front of him and suddenly felt a little weak.

Same tone, similar words......

If it weren't for the distant cousin of the Dragon Boat Festival, he hadn't seen it at all, and he even felt that it was Mr. who was standing in front of him again.

He lowered his head and said in a trembling voice, "I, I know......"

……

"Little master, come down quickly!"

"Little master, be careful......"

"Little master, danger!"

Several maids of the Li family stood under the tree, raised their heads, their faces were worried, and even their faces turned a little pale with fright.

"It's okay, it's not high at all." Li Duan looked down, waved his hand, threw down the juju on a tree branch, and said, "You guys go play, if you kick the tree again, come and call me again." ”

He jumped down from the tree, clapped his hands, and when he turned his head, he found a little girl standing under the porch looking at him.

"Who are you, how come I've never seen you before?" The first to speak was the little girl, he watched Li Duan jump down from such a tall tree, he was startled at first, and then saw him land steadily, in addition to being surprised, there was some envy on his little face.

Li Duan looked at her and said strangely, "I haven't seen you before." ”

The little girl looked at him and asked, "Do you know martial arts?" ”

"Of course!" Li Duan was a little proud and said, "My martial arts are amazing, even adults can't beat me!" ”

Seeing his smug appearance, the little girl pursed her lips, her heart must be better than him, Duan'er said in the letter last time that he could jump from the ground to the wall......

However, she wasn't sure who was more powerful between Duan'er and him, so she thought about it and said, "My little aunt is amazing, you definitely can't beat my little aunt." ”

Li Duan looked at her and asked unconvinced, "How powerful is your little aunt?" ”

The little girl thought for a while, pointed to the roof on the side, and said, "My little aunt can fly to the roof in a flash!" ”

Li Duan looked at the high roof, and his heart was a little weak.

He could jump off the roof, but not from below, and if he bragged now, the little girl would be ashamed if he asked him to prove it.

However, he didn't want to weaken his momentum in front of this little girl, and said: "What's so difficult about that, my little lady can fly to the roof at once." ”

"Then my eldest aunt will be able to fly to two rooftops."

"My aunt can fly to three."

"My dad, my dad can fly ten, a hundred!"

The little girl thought about it, Daddy has a pair of big wings, can fly very high, there must be a hundred roofs, and it is not a lie.

"A hundred?"

Who can't brag about it, anyway, she blew it first, Li Duan thought about it 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 that the sun was a big ball of fire, she thought for a while and asked, "Isn't it hot for your master to fly to the sun?" ”

"Stupid!" Li Duan looked at her and said proudly, "Won't we fly again at night?" ”

The little girl frowned and said, "That's your master, not your ......."

"Then you're 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, Duan'er will be able to protect her when she comes back......

Li Duan pursed his lips, this little girl, she likes to talk so much at a young age, she must be a big talker when she grows up.

It's still Xiaorui the best, Daddy 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 finally relieved himself after confirming from Li Yi again that he would be able to see Xiaorui in two days.

However, I don't know if his nose has broken these days, why does he always feel the smell of egg fried rice on his father's body......

……

A few days have passed since Princess Shouning's literary test to recruit horses, and tomorrow is the period of the martial arts test.

The location of the martial arts test is in the Hibiscus Garden.

Early tomorrow morning, in addition to Princess Shouning's attendance, the Queen Mother, the Queen Mother, the Queen Mother, the Imperial Concubine, and Her Royal Highness the Regent's eldest princess will all appear.

Of course, when the time comes, the Korean Chinese military minister and the Kyoto magnates will all enter the stadium to observe.

This is the biggest event in Kyoto at the end of the fourth year of Keihei.

In the Hibiscus Garden, Shou Ning looked at the clothes on the bed and said distressedly: "What should I wear tomorrow?" ”

Concubine Yan stood behind her, tapped lightly on her head, and said, "After they compete tomorrow, you will have to play in person, and these clothes will not be worn." ”

"Ah......" Shou Ning heard this, threw himself on the bed again, and muttered, "Wouldn't that be beautiful......

"What are you not wearing beautifully?" Concubine Yan pinched her face and said, "Go and borrow a dress from your imperial sister, you can wear her previous practice clothes tomorrow." ”

Shou Ning got up from the bed and said, "Oh, I can't win tomorrow anyway, so it's better to dress beautifully......"

Hall of Morning Dew.

Li Mingzhu has a plate of egg fried rice in front of her, the catering bureau has not made egg fried rice for five years, but in the past few days, every time she has lunch, there will be a plate in front of her.

A female officer walked in from outside, bowed down and said, "Your Highness, everything is arranged. ”

Li Mingzhu nodded: "I know." ”

The female official hesitated for a moment and asked, "But princess, what should you ......do with Your Majesty and the Queen Mother tomorrow?"

"I have my own arrangements." Li Mingzhu said, picked up the spoon, and began to eat.

"Yes." The female officer nodded and slowly retreated.

Somewhere in Kyoto, a fat man sneaked out of his house with a bulging baggage on his back when he was stopped by a team of guards.

This fat man who answered the first three questions correctly, but he took special care of it, and he couldn't make any mistakes, the guard looked at him and asked, "Master Peng, tomorrow is the period of the martial arts test, where are you going?" ”

The burden on the fat man's body fell to the ground, and his face was bloodless in an instant.

He hugged the guard's leg and cried: "I damn it, I'm not human, I won't sell fakes anymore, let me go, let me go......"
