Looking at Li Zhi's little head, of course, when a person shoots an arrow, you can't accurately know how many degrees to raise to hit the target.

Experienced archers are also based on experience and feeling.

On the contrary, some siege equipment, such as trebuchets, designed the length of the ladder according to the height of the city wall.

All of this requires the use of geometry.

In fact, the ancestors already knew this.

Li Zheng said: "You can start with the simplest trigonogram. ”

"Triangle? Octagonal"

"It's not the same thing as the anise, I'm talking about triangles."

"Huh."

Li Zhi nodded as he picked up the food in his mouth.

Li Tai came in time for the night, "I'm starving, do you still have food?" ”

Dahu brought a bowl of rice from the kitchen and handed it to Li Tai.

Li Tai held the rice bowl and devoured it.

After Li Zhi ate, he went to the village to find the big cow, and the twelve-year-old Li Zheng had a kind of strength to get to the bottom of everything.

They are all Li Shimin's sons, Li Chengqian, Li Tai, Li Zhi, and Li Ke have different personalities.

Pouring himself a cup of hot tea, Li was sitting on a recliner intending to pass the long night by looking at the stars.

After eating, Dahu sat aside to wash the dishes, Li Tai shaved his teeth with a bamboo skewer and said: "I have arranged all the things of the Kuodizhi, sent some people, and left some people. ”

"Hmm."

Li Zheng responded weakly.

Li Tai said again: "Now this bracket chronicle has not been compiled for three or five years, I'm afraid it will not be compiled well." ”

After speaking, Li Tai was still a little proud.

Will Li Shimin not see the problem?

A bracket chronicle has been compiled for so many years.

It is said that the prince is also a human being, and he is also the son of Li Shimin.

As an emperor, of course, he doesn't want his son to leave his side, especially his son-in-law.

For the perpetuation of the throne and the stability of the country.

is also as an emperor, family affection is far less important than Jiangshan Sheji.

Li Zheng shook the fan in his hand, "His Royal Highness King Wei, why don't you just stop being a prince." ”

Li Tai smiled bitterly: "You want me and my father to sever the father-son relationship?" ”

Li Zheng said wistfully: "It's not the same thing to go on like this. ”

Li Tai said in a low voice: "Unless you seek a concubine?" ”

Li Zheng sneered and said: "The so-called dead friends do not die in the poor way, toss His Royal Highness the Prince, His Royal Highness the King of Wei can inherit the unification, so that it is the prince who goes to the fief instead of His Royal Highness the King of Wei, so that there will be no worries." ”

Li Tai nodded very approvingly, "You see, there is still a tacit understanding between you and me. ”

Li Zheng took a sip of tea, "I'm stupid, I'm afraid I can't help His Royal Highness King Wei in this kind of thing." ”

Li Tai hurriedly said: "Li Zheng! Listen to this king tell you in detail. ”

Li Zheng: "I'm not interested in listening. ”

Li Tai still said: "You can make money, this king has power, you pay and I will contribute, isn't it an instant hit?" ”

Li Zheng smiled disdainfully, "Dead fatty, don't take me if you want to find death." ”

Li Tai: "With you as a companion on the Huangquan Road, this life is not in vain." ”

Don't speculate for more than half a sentence, Li Tai always has a desire to try for the crown prince.

If you really want to turn against each other, it may not be possible for the two brothers to do it.

Royal children are not easy to teach.

Children who grow up in the deep palace do not have a full childhood.

It is inevitable that the personality is extreme.

Looking at Li Tai's expression again, this guy yawned and wanted to sleep after eating.

In fact, Li Tai is not necessarily incompatible with Li Chengqian.

At best, it's just a rivalry between two brothers.

It's just that this kind of competition is easy to cause problems under Li Shimin's Gu cultivation method.

Noticing Li Zheng's gaze, Li Tai asked, "Why are you looking at me like this?" ”

Li Zheng sighed and said, "Doesn't His Royal Highness King Wei feel that my eyes are caring for the mentally handicapped?" ”

Reflecting on Li Zheng's words, Li Tai thought about it again and again and said: "Li Zheng, what you said just now is counting down this king, right?" ”

Li Zheng bowed his hand slightly, "How dare you do it below." ”

"You're obviously counting me down, don't think I can't see it, do you think this king is a fool."

"King Wei is too elevated to this title, how can a fool compare with His Royal Highness King Wei."

“……”

Li Tai turned around and left, and walked to Li Zheng's room to find another book to read.

Wang Ding returned to the palace and handed over the bacon in his hand to the back kitchen of the Internal Affairs Office.

The food of the eunuchs is regulated in the palace, and it is the closest eunuch to His Majesty's side.

The people of the Ministry of Internal Affairs did not dare to slack off.

Waiting until the steamed bacon and a bowl of millet rice were placed in front of him, Wang Ding said to himself: "This Chang'an order is true, the old slave clearly said that he doesn't like to eat pork." ”

Wang Ding picked up a piece of bacon and put it in his mouth to taste, looking a little surprised.

I took another slice of rice and began to eat it with a comfortable expression.

As a eunuch beside the emperor, he received a lot of benefits on weekdays.

Anyone who wants to inquire about His Majesty's mind will give some silver.

This kind of thing Wang Ding has become numb.

Everyone who has given money will write it down and present it to His Majesty.

However, the bacon sent by Li Zheng tasted surprisingly good.

Compared with silver money, such a bacon is comfortable to eat.

At least you can really feel Li Zheng's kindness.

There is no need to tell Your Majesty about this bacon.

Before dawn on the second day, Wang Ding came to the outside of the Lizheng Hall while His Majesty had not woken up.

The palace maid in the hall is dressing Li Shimin.

Standing at the door, Wang Ding said: "Your Majesty, yesterday's Chang'an order said that a part of the guards could be sent to the Turks to investigate the military situation. ”

Li Shimin's voice came from the hall, "I thought that according to Li Zheng's temperament, he would bargain, but I didn't expect to agree so happily." ”

Wang Ding bowed down and said, "Actually, Chang'an Ling still has some requirements. ”

There was silence in the Lizheng Hall for a long time before Li Shimin's voice came, "What request?" ”

Wang Ding said loudly: "The Chang'an order said that the Jingyang escort sent out to investigate the military situation cannot be commanded by the generals of the border army, but only obey the Chang'an order, and only report to the Chang'an order after returning." ”

Li Shimin put on his clothes and walked out of the hall, and said with a dark old face: "Li is just a big breath. ”

Wang Ding bowed down and said, "This is the original words of Chang'an Ling. ”

"That day, Wei Chi Gong talked to me, also for the sake of Jingyang's safety, Jingyang has movable type printing, and I naturally don't want anything to go wrong in Jingyang."

Wang Ding nodded, "Your Majesty is thoughtful. ”

"Kindly let this kid's guards go out to practice, how many guards want to make meritorious contributions, this kid is still making conditions with me."

Wang Dingfu said with a smile: "Chang'an Ling, young and vigorous, I think I will understand His Majesty's good intentions in the future." ”

Li Shimin was playing Tai Chi outside the Lizheng Palace, which was something His Majesty had to do every morning.

I get up half an hour early every day just to do Tai Chi.
