When Cheng Chuliang left, Li Yuanjia gave him two gifts.

A mathematical artifact that had been promised to him a long time ago - abacus Chen Mu and they finally made a few paintings that could barely enter Li Yuanjia's eyes because of Cheng Chuliang's good performance today, our king Han decided to give him a pair.

As for the other one, of course, it is the book "Abacus".

Li Yuanjia is very glad that when he was in elementary school, there was no shadow of computers, and the school opened the course of abacus, and he still remembers some ...... after so many years said that it is a book, but in fact, it is seven or eight pages, which records the most basic usage of the abacus in detail, and Li Yuanjia doesn't remember the high-end usage or something, or he has never learned it.

But in the course of this year, he wrote the book...... It should be said that it is a booklet, and it is enough.

If Cheng Chuliang's brain is smarter, he should be able to learn it in a day and a half, even if he has a stupid brain, as long as he reads diligently and practices more, there should be no problem in three or five days.

"It's a pity, it's just a little stupid!"

After seeing Cheng Chuliang disappear from his vision, Li Yuanjia couldn't help but sigh and shook his head with some regret.

Yes, it's a pity.

In fact, if you treat people and things in terms of receiving people and things, or some traditional knowledge, Cheng Chuliang really can't be considered stupid, at least at the upper middle level - after all, he is the second young master of Lu Guogong, and the education he has received since he was a child must be top-notch, how bad can it be?

But it's very strange that this guy just doesn't know how to do math!

Fortunately, when he was studying in his previous life, Li Yuanjia had seen a lot of such people, for example, his high school tablemate, a girl who could crush him in subjects such as Chinese, English and history, but all the excess scores were returned in mathematics, and there was even a way to make up for it!

This is talent, and there is nothing to be done.

So it was just a little disappointed, and Li Yuanjia quickly put this matter behind him. Anyway, for him, Cheng Chuliang and his future children and grandchildren are indeed very important, and it is likely to become an important factor in the promotion of Arabic numerals, but there are still decades left in his life, who knows what will happen later? Perhaps a person or thing that seems important today will not be worth mentioning in a few years......

……

In Chang'an City, Li Yuanjia is busy caring about the workshops outside the city, preparing for next month's party in Furong Garden, and more than a hundred kilometers away...... No, now it should be said that it is the first palace of the Tang Dynasty two or three hundred miles away, and on the side of Jiucheng Palace, his second brother Li Shimin is not idle, and is discussing an important decision with the ministers!

"Your Majesty, the minister still thinks it's inappropriate!"

Frowning tightly, Wei Zheng bowed and said, "Not all Turkic people are willing to surrender to my Tang Dynasty, and this rebellion led by Ashina is the best evidence!" Therefore, the minister thought that it was not enough to simply exile He Luohu to Lingnan and move the Turkic tribes to Hebei......"

"Alright, Wei Qing."

Before Wei Zheng could finish speaking, Li Shimin had already stood up from his chair and said with a firm face: "I have already said that this rebellion is just a few Turkic people who are dizzy, what does it have to do with other people?" Since they are willing to submit to my Datang, we must have the heart to accommodate them! Now that the Heluo Hurds have been exiled and the Turkic tribes have gone north, it is already a punishment for them, so you don't need to worry too much! ”

"Your Majesty!"

"Your Majesty, Your Minister......"

"Needless to say, the matter is settled!"

With a flick of his sleeves, Li Shimin no longer gave the ministers a chance to speak, and made a final decision categorically.

And hearing his words, even Wei Zheng could only close his mouth helplessly. Although Wei Zheng was notoriously hard-necked and could often persuade the emperor, he also knew that once Li Shimin made up his mind, his persuasion would be completely useless. And most importantly, the emperor's words are indeed justified, and it is indeed not very reasonable to use the rebellion of dozens of people to negate all the submissive Turks.

However, even if they were silent, Wei Zheng and several other ministers frequently flashed in their eyes at the moment they bowed their heads-Turks, you must be on guard!

Of course, Li Shimin couldn't see the change in their expressions, but he also had a deep understanding of these old subordinates, and he could guess what they were thinking at this time. So after subconsciously frowning, the emperor could only sigh helplessly in his heart.

In his heart, of course he was angry.

But Li Shimin couldn't directly attack the Turks, because he had to have the heart of the Heavenly Khan. And he knows that the current Datang does not have enough strength to really suppress the Quartet, and he must win over a group of people!

At least in Li Shimin's heart, there is a more important goal......

Thinking of this, he no longer hesitated, and waved his hand directly: "Okay, everyone, don't talk about these things...... Well, I'm going to go to the barracks to see the soldiers who were injured a few days ago, Lu Guogong, you can go with me! ”

"Yes, Your Majesty!"

Hearing Li Shimin's order, he had been silent in the hall, and the sleepy Cheng Zhijie finally came to his senses and stood up suddenly.

The others looked at each other and stood up helplessly to salute: "Congratulations to Your Majesty!" ”

If it is an ordinary emperor, it is definitely not easy to go out at will, and it is even more difficult to go to the military camp, but Li Shimin is obviously not an ordinary emperor.

Immediately defeated the world, and he is also one of the famous generals of the Tang Dynasty, Li Shimin's feelings and love for the army are not comparable to other emperors. Especially these loyal young men have just foiled a conspiracy, a mutiny, in which four guards were killed and more than ten were injured, where could Li Shimin have been ignoring it?

That's not his style!

It's just that after leaving the main hall and ordering people to prepare horses, Li Shimin still sighed and said: "More than ten people were injured this time, and I don't know how many people can survive...... I remember that there were six or seven injuries that were not light, and I am afraid that they were more than lucky! ”

Although he has long been accustomed to life and death on the battlefield, since he sat firmly on the throne of the emperor, Li Shimin has not been so close to the fight for several years. And the guards around him are not ordinary people, either they are the queens of the heroes, or they are the children of the clan, it is distressing to lose one of them, not to mention that they have lost so many at once?

However, as soon as Li Shimin's words fell, Cheng Zhijie was stunned and said, "Why did Your Majesty say this? Those guards are now recovering from their injuries, how can they be more auspicious? ”

"Huh? What do you mean? ”

After a pause, Li Shimin's eyes widened: "Cheng Aiqing, what do you mean...... None of the wounded guards died? ”

How is this possible?!

He is the emperor who fought on the battlefield, and the dead people he saw were no less than Cheng Zhijie, and as long as he looked at it that day, he knew that he would probably survive a few and die in the wounded barracks...... Now Cheng Zhijie actually told him that they were all recuperating from their injuries, and none of them died?

Under the emperor's gaze, Cheng Zhijie paused for a moment, blinked, and said, "Your Majesty, none of them are dead!" Those two little guys did a good job, and they also said that the guards were very lucky this time......"
