Seeing this scene, Li Yue shook her head, because her husband could argue with Qingque about this kind of thing.

This debate has no intention of stopping.

The little bear picked up a rabbit from somewhere.

The snow-white little rabbit was bitten half to death and had not yet died.

Putting the rabbit down, the little bear lay at his feet.

Xiao Wu looked curious and saw that the little bear was brought specially for the teacher, and now it was lying at the teacher's feet, looking fawning.

Now it is becoming more and more docile.

The aunt smiled and said: "This bear knows human nature and knows that Her Highness the Princess is pregnant with a child, so that's why she is so flattering."

Li Yue stroked its hair and said, "Kill this rabbit first."

Auntie took out a knife from her waist and started to process the rabbit.

Zhang Yang and Li Tai argued for half an hour.

"There is a saying that you can't see a rainbow without going through wind and rain. You need to have experience in life, so-called being able to pick up and put down, being able to kill the enemy with a knife, and standing under the trees in the village."

Li Tai seemed to understand a little, "Like General Li Jing?"

It is also a headache for children all over the world to use Li Jing as a role model.

Zhang Yang still nodded, "It's right to be passionate, but being able to put down your fame after a career is the highest state."

Li Tai slowly raised his head, as if looking at the highest realm.

The little fat man was silent and seemed to be deep in thought.

Zhang Yang continued to lay tiles on the roof of his new home.

Finally, the little fat man stood up again, holding a bucket of reconciled mud against the wall.

Nowadays, villagers almost regard Lishan Mountain as a forbidden area, and even children are not allowed to go up the mountain at will.

It seems that wherever the owner of this fiefdom is, it is forbidden territory, let alone strangers entering the village.

It is good for villagers to have cohesion, at least to protect their own property.

After the tiles were laid, Li Tai also finished two walls.

The two of them walked to a big rock and sat down. Zhang Yang drank a sip of water while wearing a vest, and then handed him another water bag.

Li Tai took several sips of water and wiped the sweat from his forehead.

A gust of mountain breeze blew by and it was a bit cool.

Li Yue brought a coat and put it on Zhang Yang, "Husband, please don't catch a cold."

Li Tai held a branch in his hand and wrote a math question on the ground.

This question looks a bit familiar.

Thinking back again, this seems to be the math problem I gave Kong Yingda.

After Li Tai finished writing, he frowned and said: "This question is this year's imperial examination question. Only now in the imperial court have this year's policy theory and Ming Jing questions come out. Other questions in the Ming calculation subject are also acceptable, just this math question.

Da'an is the only one who can answer the question accurately."

Zhang Yang nodded in understanding.

Seeing the indifferent expression on his brother-in-law's face, Li Tai added: "I know that my brother-in-law is proficient in mathematics, so I have been looking at this problem for a long time. Many people in the court are discussing how to solve it."

"Actually, it's easy to solve this math problem."

Zhang Yang looked at the question. In fact, this is a way of understanding numbers. It is also a relatively basic understanding in numerology and can be extended continuously.

Li Tai hesitated and said: "How to solve it."

The sun was setting on the horizon, and Zhang Yang said to him: "Goldbach's conjecture."

"What guess?"

Zhang Yang took the branch from Li Tai's hand, wrote numbers on the ground, and said: "We all know that there are even numbers and odd numbers, or prime numbers. Can His Highness King Wei understand this common sense?"

Li Tai kept blinking, "What is a prime number?"

Zhang Yang continued to write on the ground, "For example, this one cannot be divisible by any other integer except the number one itself. It is composed of two positive factors, which also involves divisors."

Li Tai nodded, "It's so profound, I can't understand it at all."

Zhang Yang held his forehead in distress, "The so-called Goldbach's conjecture, for example, any even number greater than two can be expressed as the sum of two prime numbers, and an even number can be divided into the sum of two prime numbers."

Xiao Wu was passing by on a bear, "This kind of math problem is really interesting and very mysterious."

Li Tai was silent at this moment. He sat there without saying a word. He thought it was not difficult to count the skills, but after hearing what his brother-in-law said, he found it very difficult.

Zhang Yang patted him on the shoulder, "But this is just a conjecture. If there is no need, don't delve into it. As far as I know, no one has been able to solve Goldbach's conjecture."

"Any even number greater than two can be expressed as the sum of two prime numbers..."

Xiao Wu put his hands behind his back and explained: "For example, if A equals D plus B, then D and B must be prime numbers, and A must be an even number, because only the sum of the numbers with these two characteristics must be an even number."

Zhang Yang nodded, "That's right."

Xiao Wu grinned, showing his white teeth.

"It's getting late, let's go home."

"OK!"

Xiao Wu followed the teacher and master down the mountain.

Li Tai looked at the words written on the ground, and his brain was in a state of shutdown at this moment.

"Your Highness, King Wei? What are you having for dinner?" the guard came over and asked cautiously.

After recovering from the downtime, Li Tai stood up slowly, "Did you see these words written on the ground?"

"I saw it."

"Copy these words and send them to the palace to the young slaves."

"Here."

I wanted to help Zhinu solve the problem, but even my brother-in-law said that this kind of math problem is both advanced and basic.

He couldn't get an answer from his brother-in-law, and there was nothing Li Tai could do.

In terms of intelligence, he can be admired by his younger brothers and sisters, but when it comes to this kind of knowledge that he has never been exposed to, Li Tai feels that his intelligence is not enough at all.

Especially for the study of number theory, no one can spend his whole life studying this knowledge like Li Chunfeng.

"His Royal Highness the King of Wei hasn't said what you want to eat tonight?"

Li Tai said with a straight face, "Let's eat vegetable leaves tonight."

"I understand."

"Add some minced meat."

"clear."

"Remember there is still some bacon left to eat, so you should eat it all."

"good."

Every time Li Tai said something, the guard nodded.

"My intention is that we all eat vegetable leaves tonight, and you should eat them too."

"But it's a humble job..."

Li Tai walked down the stone steps, "But what?"

The guard looked bitter, "But I have been eating vegetable leaves for half a month, and I always feel like there is nothing in my stomach recently."

This chapter is not over yet, please click on the next page to continue reading! "Then you should also add some minced meat, and don't even eat the minced meat if you talk nonsense."

"I understand." The guard could only smile.

Ever since His Highness King Wei made up his mind to lose weight, everyone who came out of Prince Wei's Mansion had not eaten properly. When King Wei ate vegetables and leaves, everyone also followed suit.

Life was hard and he really didn't want to work anymore. The guard sniffed with a sad look on his face.

These days, the court has returned to calm days. Li Shimin is in a pretty good mood and is listening to Li Junxian's report.

"So, the conflict between the prince and Su Dan was due to the opening of the official school, and he even came to apologize?"

"This is indeed what the general's eyesight saw."

Li Junxian lowered his head and continued: "Recently, the new censor Xu Xiaode seems to be holding on to Yan Shigu's affairs and pestering Lu Chengqing. I heard that some clues have been found."

Li Shimin nodded and said, "Let him continue the investigation."

"Well, I will retire at the end."

After standing alone in the dark Manna Hall for a long time, Li Shimin summoned a eunuch and said, "Tell the queen that the marriage between the prince and Su can be arranged."

"Here."
