"Queen Mother, don't you know, when the teacher calculates the answer, the doctors and students of the Guozijian present are surprised."

"Is that an exaggeration?"

"You don't understand. You can't even count them. ”

"Brother Crown doesn't understand, Lizhi has already learned."

"What is thirty-two divided by one hundred and twenty-eight?"

"Mother, brother, he bullies!"

Empress Eldest Sun couldn't stand it either, and asked, "Then do you know how much it is equal to?" ”

Li Chengqian was very honest, and spread his hands and said, "Erchen doesn't know either." ”

"......" the eldest grandson of the queen.

"But the teacher knows it, and he can calculate it at a glance, and he doesn't need to calculate it at all."

In fact, Li Chengqian is just talking nonsense, and even the above two numbers are made up by himself.

Li Chong didn't even count thirty-two divided by one hundred and twenty-eight.

However, this did not affect his admiration for his teacher in the slightest.

His teacher is the smartest in the world!

Terrifying!

Then he was almost punished by Empress Changsun to do a hundred arithmetic problems.

The ancient gentleman has always had to learn arithmetic, and he is also one of the six arts.

It's too difficult, and the eldest grandson queen won't ask for it.

But at least......

Some simple ones, the prince himself has to know it.

asked the prince if his teacher had taught him arithmetic, the prince shook his head, and the eldest grandson queen asked him to go back and ask his teacher to teach him arithmetic.

blame Li Chong, as the prince's teacher, why didn't he teach him arithmetic.

Li Lizhi smiled at this time, seeing that you are still angry.

……

And since Li Chong held an exchange meeting in Guozijian.

More and more people came to visit the door in the future.

Some came to see if Li wanted a daughter-in-law, and some came to ask him to answer his questions.

Those who intentionally or unintentionally asked him if he wanted a daughter-in-law, Li Chong directly refused.

Because it's not something you can afford.

For those who came to ask for answers, Li Chong had no choice but to tell them to prepare pen, ink, paper and inkstone by themselves.

Because......

This is the most basic stationery or something, you still have to prepare it yourself.

Otherwise......

How much more money will be spent in his house for no reason.

Wang Xiaotong has now also relied on Li Chong.

made Sun Simiao want to come to visit one day, and he was almost embarrassed to enter the door.

Now Li Chongna is not famous, and some people even say that he can count all the moons in the sky.

As for who made the rumor......

Use the method of elimination first! It definitely won't be Li Chong himself.

Because Li Chong is so idle that his eggs hurt, he will promote himself like this.

Now that you've finished counting the moon, is the next step to count the sky? Then the next step, is it going to be beheaded?

"Master Li alone alone, even if he reaches the sixteenth place after pi, that is, Liu Hui and Zu Chong's father and son, they are far behind. However, this calculus is quite similar to the "Fixation Technique" written by Zu Chong's father and son. Merely...... Master Li, this one of yours is even more illusory, like a rootless Ping, while Zu Chongzhi's father and son are more inclined to start from practical problems. ”

Speaking of which, the name "Embellishment" seems a little familiar, where have you heard of it?

"The old man also brought "Fixation" today, there are some questions in it, I want to ask Mr. Li to try to answer them."

Li Zhong remembered, isn't this the legendary one, no one in Datang can understand it, even many doctors can't understand it, so it was finally abandoned by the academy and didn't learn? This is a treasure in the world of Chinese mathematics.

Some people even speculate whether the level of mathematics in China has declined since the Northern and Southern Dynasties, because no one can understand what Zu Chongzhi's father and son wrote.

Immediately, Li Chong took the book in the other party's hand and read it.

He quickly said, "This book is indeed a bit obscure. ”

Mainly, this ancients' things, many times, have to be the same as doing Chinese reading comprehension, which is definitely a challenge for Li Chong.

He had to find his concubine and study it together.

"You put the book here with me, if I have time, I'll see if I can solve it."

"Then I'll bother Mr. Li."

"Speaking of which, the old man has already recommended to His Majesty that Master Li be a doctor in Guozijian. Your Majesty told Master Li about this? ”

After speaking, Wang Xiaotong saluted embarrassedly and said: "It's the old man who is abrupt, but the old man thinks that with Bachelor Li's knowledge, it would be a pity if he couldn't carry it forward." ”

Li Chong said: "Your Majesty hasn't told me yet, maybe I'll say it next, I haven't entered the palace recently." Actually, I don't know much, and if I say that I want to be a doctor for a long time, I'm afraid that I will soon be unable to teach, so I ...... It is okay to set aside a time every year for interested people to get together and learn, ten days and eight days. ”

"Then the old man thanked Master Li on behalf of all the teachers and students of Guozijian."

"Eh, why do you need such a big gift. It's nothing, it's just a gesture. ”

"The old man also wants to ask His Majesty to re-annotate all the calculations together."

"Ahem......"

"What's wrong with you, Master Li?"

"Nothing."

Alas, what is the trouble?

But the key is that he can't refuse, if you refuse, he will say that you don't want to teach others, stingy.

Now the official arithmetic books of Datang add up, there should be, there are about ten, of which nine chapters of arithmetic are the most important of the ten, because it is more daily and systematic in arithmetic, and there are more examples. Other books are more specialized in a certain aspect, for example, there are "Zhou Ji Sutra" which specializes in astronomy, and there is also "Island Sutra" which specializes in calculating the height and depth of island valleys.

To be honest, there are some questions, even Li Chong, may not be able to understand.

But it's still that sentence, what can hinder him is only the problem of classical Chinese translation.

He worked hard, and he should be able to solve the problem, not to mention 100 percent, but eighty or ninety percent should still be fine.

"Speaking of which...... Does Mr. Li plan to write a book of reckoning himself? ”

"This ...... I'm not qualified yet. ”

In the old man's opinion, Master Li is fully qualified to do so. Moreover, the old man also wanted to see Master Li's works as soon as possible. ”

Li thought about it for a while, and then said, "I'm free, no, I'll do my best." ”

Originally, Li Chong wanted to refuse, but soon, he thought about it, isn't this a good way to hide at home and fish, damn it, he is really a genius.

If others say why he doesn't go on duty, he will say that he wants to compile the official Datang book.

If someone asks him to write a reckoning book in bed?

Then he replied to the other party that he was going to find inspiration through this.

Well!

That's a good excuse!
