Li Yue shook his head at this scene, just because of this kind of thing, the husband can also argue with Qingque.

There is no intention of stopping this argument.

The bear didn't know where to get a rabbit in his mouth.

The snow-white rabbit was bitten half dead at the moment, and he didn't breathe.

Putting the rabbit down, the bear crouches at his feet.

Xiao Wu looked curious that the bear was specially brought for the teacher, and now he was still lying at the teacher's feet looking flattering.

Now it's getting more docile.

The aunt smiled: "This bear is human, and he knows that Her Royal Highness the princess is pregnant with a child, so he is so flattering." ”

Li Yue stroked its fur, "Let's kill this rabbit first." ”

The aunt took out a knife from her waist and began to handle the rabbit.

Zhang Yang and Li Tai argued for half an hour.

"There is a way to see a rainbow without experiencing wind and rain, life must have experience, the so-called can afford to put it down, can lift a knife to kill the enemy, and can also be under the tree at the head of the village."

Li Tai seemed to understand a little, "Just like General Li Jing?" ”

It is also a headache for children all over the world to take Li Jing as an example.

Zhang Yang still nodded, "It's right to be enthusiastic, but being able to put down your fame after breaking through is the highest realm." ”

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

The little fat man was silent, as if he was lost in thought.

Zhang Yang continued to tile the roof of his new home.

At last, the little fat man stood up again, and he carried a bucket of mud against the wall.

Now the villagers are about to regard Lishan as a forbidden place, and even children are not allowed to go up the mountain at will.

It seems that where the owner of this fief is, there is a forbidden place, not to mention strangers entering the village.

It is good for the villagers to be cohesive, at least to protect their own property.

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

The two walked to a large rock and sat down, Zhang Yang took a sip of water in his vest, and then handed him another water bladder.

Li Tai poured several mouthfuls of water and wiped the sweat from his forehead.

A gust of mountain wind blew and it was a little cool.

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

Li Tai held a branch in his hand and wrote a number problem on the ground.

This question looks familiar.

Thinking about it again, this seems to be the math problem I gave Kong Yingda at the beginning.

After Li Tai finished writing, he frowned and said: "This question is the topic of this year's imperial examination, and it is only now that this year's policy theory and Ming Jing questions have been passed out. ”

Zhang Yang nodded knowingly.

Seeing his brother-in-law's indifferent look, Li Tai said again: "I know that my brother-in-law is proficient in mathematics, and I have been looking at this question for a long time, and 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 topic, in fact, this is a way of understanding numbers, and it is also a more basic understanding of mathematics and an understanding that can be extended in the foundation.

Li Tai hesitated: "How to solve it." ”

The sunset was on the horizon, and Zhang Yang said to him: "Goldbach conjecture." ”

"What conjecture?"

Zhang Yang took the branch in Li Tai's hand, wrote numbers on the ground, and said: "We all know that there are even numbers and singular numbers, or prime numbers, can His Royal 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, except for the number one, cannot be divided by other integers, and is composed of two positive factors, which also involves divisors. ”

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

Zhang Yang held his forehead in distress, "The so-called Goldbach 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 split into the sum of two prime numbers. ”

Xiao Wu was riding a bear passing by, "This kind of math problem is interesting, very mysterious." ”

Li Tai was silent at the moment, he sat in place in a daze without saying a word, he thought it was not difficult to do mathematics, but he felt difficult to hear his brother-in-law say this.

Zhang Yang patted him on the shoulder, "But this is just a conjecture, if there is no need to delve into it, as far as I know, no one has been able to solve the Goldbach 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, A is equal to Ding plus B, then D and B must be prime, and A must be even, because the sum of the numbers with only these two characteristics must be even. ”

Zhang Yang nodded, "That's right." ”

Xiao Wu grinned and showed a mouthful of white teeth.

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

"Okay!"

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 the moment.

"His Royal Highness the King of Wei? What's for dinner? The guard walked over and asked cautiously.

Coming back from the state of downtime, Li Tai slowly stood up, "Do you see these words written on the ground?" ”

"See."

"Transcribe these words and send them to the palace to be handed over to the slaves."

"Whoa."

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

There was no answer from his brother-in-law's side, and Li Tai couldn't do anything.

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

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

"His Royal Highness King Wei hasn't said what to eat tonight?"

Li Tai made a straight face, "Eat vegetable leaves tonight." ”

"Humble duty understood."

"Add some meat foam."

"Understood."

"I remember that there is still some bacon that I haven't eaten, so I've eaten it all."

"Okay."

Every time Li Tai said a word, the guard nodded.

"This king means that you will all eat vegetable leaves tonight, and you will eat them too."

"But it's a lowly ......"

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

The guard looked bitter, "But I've been eating vegetable leaves for half a month, and I always feel like there's nothing in my stomach lately." ”

"Then you also add some meat foam, and don't even eat meat foam if you talk nonsense."

"Understood, understood." The guards had no choice but to laugh.

Since His Royal Highness King Wei made up his mind to lose weight, all the people who came out of King Wei's mansion have not eaten well, and King Wei eats vegetable leaves, and everyone has to eat vegetable leaves.

The days are hard, I really don't want to do it, the guard sniffed and looked sad.

These days, the court has returned to calm days, and Li Shimin's mood is not bad, and he is listening to Li Junxian's report.

"In this way, there was a conflict between the prince and Su Yan because of the opening of the official school, and he went to apologize?"

"That's exactly what the Admiral's eyes saw."

Li Junxian lowered his head and said: "Recently, the new imperial historian Xu Xiaode seems to be still holding on to Yan Shigu's affairs, and he is entangled with Lu Chengqing, I heard that he has found some clues. ”

Li Shimin bowed his head and said, "Let him continue to investigate." ”

"Well, the last general will retire."

Standing alone in the dimly lit Ganlu Hall for a long time, Li Shimin summoned a eunuch, "Tell the queen that the marriage between the prince and the Su family can be arranged." ”

"Whoa."

The emperor's mind is difficult to fathom, and His Majesty was a little hesitant before, but now he has made a decision.

Late at night, Li Chengqian slept in the East Palace.

It is very windy at night during this season, and there is always a strange sound when the wind blows through the temple.

The desolate East Palace is even more gloomy under this night.

Three or two eunuchs carrying lanterns hurried to the East Palace.

All the way to the outside of the East Palace, they told the guards here the reason, it was His Majesty's inner chamberlain and eunuch, and they didn't dare to ask more, so they took it to the prince's bedroom.

"Your Highness, Your Majesty has sent someone to deliver the message."

Li Chengqian slept in a daze, "What words." ”

The eunuch standing outside the hall said loudly: "Your Majesty said that the prince's marriage is already being prepared, and he will marry the Su family on a day next year, and ask the prince to prepare early." ”

"Well, Lone knows."

Li Chengqian was still confused and replied, and then mentioned that it was the Su family.

Li Chengqian, who was still asleep, got up from the bed, walked quickly to the door, and immediately pushed open the door and said, "Really? ”

"It was His Majesty who personally confessed, and the old slave delivered the words and retired."

Li Chengqian stood in place for a long time.

The night wind blew, and the guards advised: "Your Royal Highness the Prince, don't catch a cold." ”

Li Chengqian smiled stupidly, "Lone is getting married." ”

The prince is now one in twenty years old, and he will be twenty and two in the next year, and it is normal to get married at this age.

In the middle of the night, Li Chengqian had no heart to sleep.

Until the morning of the next day, Zhang Yang did not see the prince in the court, and after some inquiry, he learned that the prince had not slept all night, and he had a cold in the morning, and he was still languishing.

At the beginning of the normal dynasty, Zhang Yang listened to the reports of various ministries and the arrangements of Zhongshu Province for the affairs of the Hexi Corridor.

This time the early dynasty ended quite smoothly.

At least there is no arguing.

After getting off the court, Zhang Yang walked towards the East Palace, and unexpectedly found that there was a figure who was on the same road as him, "Xu Yushi also went to visit the prince?" ”

Xu Xiaode arched his hand and said: "At the beginning of the East Palace, His Royal Highness the Crown Prince took care of the lower officials, and when he learned that the prince was sick, he wanted to visit. ”

Zhang Yang nodded, "It's okay, let's do it together." ”

After a moment's pause, the two continued to walk towards the East Palace.

"Zhang Shangshu asked his subordinates to inquire more about clues related to Lu Shangshu, and found out some clues these days."

"Congratulations, I don't know what the situation is now?"

Xu Xiaode's expression was solemn, "The lower officials found a family in Chang'an City, guessing that it was Lu Chengqing who placed the money, and was about to inquire only to find out that they left Chang'an City with their belongings that night." ”

"Xiaguan naturally refused to give up, and chased people out after a day, but found the body of that family, which was intercepted and killed halfway, and the clue was broken."

Zhang Yang gasped when he heard this, "Intercepted and killed?" ”

Xu Xiaode nodded, "It has been reported to Dali Temple to investigate, and now it is said that he was killed by mountain bandits, what does Zhang Shangshu think?" ”

I don't know how Xu Xiaode investigated, Zhang Yang whispered, "Since the other party has such an abnormal behavior, it means that Xu Yushi's direction is probably right, otherwise such a disaster would not have happened." ”

"The lower officials think the same."

Zhang Yang said again: "But looking at the other party's posture, if you dare to kill people and transfer your family, you are very ruthless, and the background must not be simple." ”

Xu Xiaode said in a low voice: "The lives of a family of five are so unknown and gone, and the lower officials must investigate them to the end." ”

Walking to the front of the East Palace, Zhang Yang said: "Some things you will inevitably encounter risks and obstacles when you do them alone, I know that there is a group of people in Chang'an City who like to do this kind of thing to punish evil and promote good, maybe they can help you." ”

"Those people are all reckless, and the affairs of the court must be done in the way of the court." Xu Xiaode's gaze was firm, "Xiaguan won't go to them for help, and Zheng Gong also promised to send more people to Xiaguan." ”

The affairs of the court should be done in the way of the court......

Zhang Yang stood a step or two behind in place, and there are always so many corrected people who can make this world more interesting.

Follow in his footsteps and walk all the way into the East Palace.

At this moment, in the sleeping palace of the East Palace, Lu Zhaolin was diagnosing Li Chengqian's pulse.

Before he could get close to the prince, he heard the voice.

"The prince's wind and cold are not serious, he may stumble when he speaks in these three days, cultivate for half a month, take medicine for one day, and cultivate for three days to speak normally, and then cultivate for half a month."

After speaking, Lu Zhaolin got up and was about to leave, but when he turned around and saw Lu Zhaolin, Zhang Yang smiled and said, "Brother Lu, I haven't seen you for a long time." ”

Lu Zhaolin saluted with a tangled expression, "Zhang Shangshu." ”

"What have you been busy with lately?"

"The lower official has resigned."

Without saying a word, Lu Zhaolin left in a hurry.

Seeing that Xu Xiaode was very curious, "This Supervisor Lu of the Imperial Medical Department knows Zhang Shangshu, why does he not have a good face like this." ”

Zhang Yang sighed: "It's a bit of a holiday. ”

"Holidays?"

"Well, it's been a few years since the holidays."

"I see."

The two walked to Li Chengqian's bed, saw that his face was pale, and they smiled stupidly.

Zhang Yang couldn't help but ask, "What is His Royal Highness the Crown Prince laughing at?" ”

Li Chengqian said stupidly: "My father sent someone to let Gu prepare to marry Su's marriage. ”

Zhang Yang nodded, "It's a good thing." ”

Li Chengqian still had an idiotic smile on his face, "Zhang Yang, I owe you a great favor." ”

"What's this, the prince and I are not only monarchs and ministers, but also friends, I will retire early in the future and hope that the prince can also start a family."

Li Chengqian put away his smile, "What? Are you retiring? ”

Zhang Yang waved his hands, "I will be thirty years old in seven years, and it should not be strange to retire from the court at the age of thirty." ”

“……”

The hall was quiet for a long time, and Zhang Yang said again: "Why does Xu Yushi look at me like this?" ”

Xu Xiaode said: "It is said that thirty years old is the time when a person is in the prime of life, how can he retreat lightly. ”

"Ahem...... "Ahem" first cleared his throat, and then Zhang Yang spoke, "There is a Taoist priest who said that I will be seriously ill at the age of thirty, and I will not be able to go to the court. ”

Xu Xiaode pondered for a moment, and then saluted, "Since Zhang Shangshu has the heart to retreat, why bother making such a ridiculous excuse, do you think the lower officials will believe it, and the lower officials feel offended." ”

"I'm going to retire at the age of thirty, and I don't need you to take care of it."

"Thirty years old is the most important and most important age in a person's life, don't waste your prime, regret it in your old age, I still remember the words that Zhang Shangshu gave to the prince back then, empty and sad."
