The next day.

Li Zhong rode a horse to find Li Er.

Li Er is now majestic, and he has finally entered the Taiji Palace.

The area of Taiji Palace should be at least 2.5 times the size of the East Palace, Li Chongchai.

But the key is the back garden, which is definitely more than a little bigger than the East Palace.

In fact, Li Er is also a person who likes to be greedy for pleasure in his heart.

This is very similar to Li Chong.

It's just that the external environment of Datang does not allow him to be greedy for pleasure.

"You've come just in time!"

Liangyi Palace.

Li Chong had just walked in a few steps when he immediately heard Li Er's voice.

"The minister has seen Your Majesty!"

Someone is here, you have to be respectful to Li Er, if there is no one, Li Dazhong will sit directly on the mat with his legs apart, and there is no shape.

Li Er said to Li Chong: "Today, everyone suddenly talked about whether your arithmetic is strong, or Li Chunfeng's arithmetic is strong in the Taishi Bureau. ”

Li Zhong has already begun to secretly think in his heart, are you so boring?

However, as soon as he saw that the eldest grandson Wuji was also there, Li Chong knew that it must have been instigated by this goods.

Li Chong is at least 99 percent sure.

The point is that the prince is also there today.

He sat right down to Li Er's left hand side.

The reason is that Li Chunfeng has nothing to do today, and suddenly he is sparse, saying that he wants to reform the armillary sphere.

The so-called armillary sphere is an ancient instrument used to measure the spherical coordinates of celestial bodies and to demonstrate celestial phenomena.

This thing should be used in conjunction with the Heavenly Theory.

It's just that today's Datang and Hun Tianshu have not been widely recognized by the society.

Only the most cutting-edge scientific research positions like the Taishi Bureau will believe that the sky is definitely not round, and the earth is definitely not square.

But if you want to explain your own doctrine, you have to build a model, and that model should match the celestial phenomena that you can see with the naked eye.

It's like saying......

You use your own theories to calculate when and where in the sky Venus will appear.

Then when others see that this is the case, they may believe that your doctrine is true.

And Li Chunfeng's restructuring this time should be to find that the old model that was originally placed in the Taishi Bureau is no longer accurate, which is not convenient for their Taishi Bureau to use to observe celestial phenomena, so they have the idea of wanting to restructure.

Of course!

None of that matters now.

The important thing is that Li Chunfeng joined the army in the Clerk's Office of the Qin Wangfu since he was seventeen years old, and his arithmetic skills are good, which everyone knows.

And Li Zhong claimed that his arithmetic was invincible in the world.

The eldest grandson Wuji wanted to see if Li Chunfeng was a little more powerful, or Li Chong was a little more powerful.

Let's be honest.

Li Zhong felt that the monarchs and ministers of the Tang Dynasty were quite idle.

It is estimated that there are meetings every day, just sit there every day and brag about it.

“…… Or, you want to compare with Li Chunfeng? ”

In the middle, Li Chong didn't hear it.

Li Zhong glanced at Li Er in his heart, he was really full and had nothing to do, no wonder he would do such a thing as forcing the daughter-in-law of the old house to be jealous. However, the old house is also miserable, and it is impossible to take a concubine. So, do you think that if you marry a woman from another family, and if you don't marry a princess, you will be able to have a group of wives and concubines? You want to be beautiful. It depends on whether the mother's family has power.

Li looked at the person sitting there, sitting in the middle.

is about twenty-six or seventeen years old, this must be Li Chunfeng.

Li Chunfeng also looked back, to be honest, he also had some understanding of Li Chong, for example, his one from one to one hundred, to tell the truth, he didn't know how to calculate it at first, until the people he worked with were so fast that he didn't allow him to think, so he said the method, and he suddenly realized.

It turns out that it can still be counted like this!

It's a bit clever.

I heard that this is just some of Li Chong's skin, to be honest, he has long wanted to know Li Chong, after all, in today's Tang Dynasty, there are not many people who like to study arithmetic, most of them are just regarded as a hobby, but this is actually also because learning this, there is really no future, at most to give an eight-grade or nine-grade official, it is already the top of the sky.

See a real person at this time.

But it's younger than expected.

He couldn't help but give Li Chong a cross hand salute.

Since the other party is so polite, of course Li Chong has to give the other party a salute back.

"How do you compare?"

Let's be honest.

Li Zhong is a little empty.

After all, a person like Li Chunfeng, even if he is put into the next generation, must be a scientist-like existence, a top genius in the scientific world, and he is just an ordinary college student.

What if you lose later?

But the situation at this time does not allow him to back down, after all, there is no such thing as surrendering and losing half here.

The eldest grandson Wuji said: "It's like counting the scriptures." ”

it!

Aren't you bullying?

Li Chunfeng is the existence of compiling books for the Tang Dynasty, if you use the scriptures to test him, then of course the other party is easy, and if you use it to test Li Chong, then Li Chong must be very difficult.

Of course, Li Chunfeng is definitely not to the level of compiling a book now, but he must have already turned over the topics on the scriptures.

Really!

Li Chunfeng is a righteous man and gentleman, and when he said: "I have read the content of the scriptures more than a hundred times, which may be unfair to Master Li." ”

Fang Xuanling also opened his mouth and coaxed: "How can that compare?" ”

Li Chunfeng said: "It's better for each of us to give each other a question, and give three questions respectively to see who answers more correctly." ”

"This is good!"

Who!

Who's saying it!

Li Chong turned his head and saw that he didn't know much about this person.

But looking at this position, on an equal footing with Fang Xuanling, is he Lao Du? Du Ruhui? Du Ruhui was very short-lived, because it was too short-lived, so even Li Chong didn't know when he died.

But it should have died in the early years of Zhenguan.

There are not many descriptions of him left in history, only that he is a very smart person and very good at making ideas, so there is a saying that 'Fang Mou is decided'.

"This is ......"

Li Chong asked.

Because Du Ruhui didn't talk much before. Because smart people don't like to talk very much, Li Chong has always paid little attention to this person.

It's just that today he suddenly spoke, so Li Chong noticed him.

In fact......

It's not that Li Chong doesn't want to know these Zhenguan celebrities, but if you know a lot, it's not good, after all, who knows if you want to form a party.

Therefore......

Li Chong has always restrained himself, and he only needs four beautiful concubines.

What's more, he's not a, he pays attention to what these men do.

He might as well pay attention to the "Women's Clothing in the Early Tang Dynasty - Underwear" and write it as a paper and pass it on to future generations.

"Shangshu's right servant shoots - Du Ruhui."

Li Er also opened his mouth to introduce him.

"Oh."

Li Chong nodded.

Why is Lao Du in such a good mood today, after eating honey, he can actually speak?

"Hmm...... Let's have three questions each. Li nodded in agreement.

I am the prince's teacher anyway, if it is really a loser, then there is nothing to say. It's like you haven't learned home yet. But if you fight directly, it will be a real shame.

And......

Li Zhong felt that the other party would definitely leave a little thin noodles for himself, otherwise, why should there be three questions, instead of one to determine the winner or loser, in fact, everyone learns from each other, loses and wins, so that everyone can get by on face and learn from each other.

Subsequently......

Li Er asked people to bring pen and ink and calculate chips.
