"This...you can go back as a question of thinking."

"Anyway, thinking so, is absolutely correct, but how should this formula be listed..."

Li Zong immediately kept it a secret and smiled, "I won't talk about it here for now."

Finally, I suddenly became interested, but Li Zong stopped talking.

This boy really makes people want to hit him.

But that's right, the old man Hengxun quickly suppressed his anger.

He said, "At this point, I think we can write it out even if my friend doesn't say it."

Li Zong also said, "Then let's try it."

Zhang Gongchuo had already begun to bow his head and think hard.

He felt that he had grasped the key to the problem, but it seemed to be of no help.

"If you require pi, you must regard pi as an unknown number, and two equations like this must be written."

"But where do these two equations come from?"

"Fangtian Art? Rectangle?"

"This is one of them, but this one is enough to calculate the pi, even if this rate may not be accurate."

“…”

Li Zong naturally heard his muttering, and the other party tried to start with the formula of the area of ​​the circle, but the formula of the area of ​​the circle itself was deduced by a rectangle.

Unless the area of ​​this rectangle can be equal to the area of ​​another figure, even the area of ​​this rectangle can only rely on imagination, guessing, and measuring.

It is impossible to calculate the correct answer in this way.

Seeing that Old Man Zhang was trapped in, Li Zong summarized the key points of today's knowledge, and then assigned five homework and withdrew.

...

at the same time……

Outside the Li Mansion.

Cui Juan and others are becoming increasingly unable to understand.

People like Heng Xun, Zhang Gongchuo actually came to Li’s mansion to find Li Zong again.

The three of them bribed the groom by inquiring about their grooms and only then did they find out Heng Xun's identity.

Heng Xun!

That was one of the "Giyang Eight Das" and they said why this name sounds so familiar, it turned out to be him!

But even these two people did not come to Li Zong, but asked the two old people to come to him. Li Zong was really ignorant.

"It's out! It's out!"

Xu Yuanying was watching the wind and saw that the gate of Li's mansion was opened again, he quickly patted the two people next to him.

The two of them were also excited and looked over here.

"I'm just about to ask Hengxun for advice. Why don't we come to visit us later?"

But Liu Heng looked at the sky and said, "At least it's Shen Shi now. I feel like I need to ask for advice, but I won't be able to ask for advice for a long time."

"Why don't you? I'll be afraid that they will leave the next day."

"I'm not afraid of this. I'm living in the same poster, so just pay attention."

...

It was early the next morning.

Knowing that the two of them had not left, and they were still there in the morning and did not go out, the three of them also visited each other.

And the two of them were naturally reviewing their homework two days ago. When they heard the boy say that someone was visiting him, they had to put down their pen and come out to take a look.

This happened to save Heng Xun from the abyss of equations.

As for Zhang Gongchuo's side, he is already crazy, so it's better not to bother him.

When he came outside, Heng Xun could tell at a glance that they were three young people he had met in Li's mansion two days ago.

When Cui Juan and the other two saw Heng Xun coming out, they immediately bowed and said, "Students have met Heng Gong."

"No need to be polite! I wonder what the three little friends have to do?"

Cui Juan said, "There is nothing important, but suddenly I heard that Heng Gong is nearby. In the past, students had some unknown meanings in books and scriptures, so I wanted to ask Heng Gong for advice."

Liu Heng: "Yes! The three of us have admired Heng Gong for a long time."

Then Heng Xun heard this and couldn't help but joke, saying, "You guys wouldn't have come up to challenge me like they did three days ago?"

Seeing the three of them feeling embarrassed, Heng Xun also laughed and said, "Kidding, just kidding, anyway, if you have anything to ask for, let's talk about it... over there, Gong Chuo needs to study mathematics, so don't bother him."

When the three of them heard this, they were all happy and thought that Henggong liked to support the backwards, which was true!

In fact, Heng Xun is also thinking about something these days.

That is, what will happen next after not becoming an official? It is good to live in seclusion, but no one knows about his own knowledge.

Of course, you have to teach people.

This is definitely not something that is taught casually. It depends on the person and whether the person being taught has insight.

Otherwise, he would be no different from those teachers.

After everyone sat down, Heng Xun seemed to have finally found his home court and said, "Tell me, what do you all don't understand?"

...

The boy then visited the three people outside the door, and told Zhang Gongchuo about Heng Xun's hospitality outside.

Zhang Gongchuo didn't think so, but said, "Juye is not very interested in numbers. The meaning of classics and clear talks are his strengths. There is no obstacle."

The boy said, "Is this Li Zong really that powerful? Even if you master, your numerology skills are not as good as the other party?"

Zhang Gongchuo said, "I don't think this guy is an ordinary person. He is a real person with great knowledge. Not to mention me, I am the capital, and even the whole world, I'm afraid he is not as good as him."

...

Li's Mansion.

Li Zong sneezed, who was talking about him behind his back?

When Su Ying'er saw him sneezing, she also asked, "Husband, are you catching a cold?"

Li Zong replied: "No. But I have indeed lacked some exercise these days, and I feel like I am a lot more decadent."

Originally, Li Zong ran three kilometers every morning.

Now I've become much lazy.

Who made Su Ying'er feel comfortable holding her, and the soft jade smelled like a fragrance.

Although you can't do that, there's no problem holding it.

Because I was in the boudoir, I was not very resistant to holding Su Ying'er.

Of course! All of this has to be based on the handsomeness of Li Zong.

Later, I saw that Li Zong's clothes seemed to be quite old.

This was what she saw when she was rummaging through the closet yesterday, and she said, "Why don't I make you a new outfit, husband."

"Do you know?" Li Zong also asked.

However, this sentence is a bit redundant, because in ancient times, there was no needle or thread.

Most of the time they usually use this to play time.

But then Ying'er said, "It's just that Ying'er is making it for someone else's first time, so if the last thing is not good, then please don't laugh at Ying'er, my husband."

Li Zong said: "How could this happen? But can it be customized?"

"Customized?" Ying'er also said with a questioning look on her face.

"That's right, I'll draw it, you'll make it." Li Zong learned courtyard design, but his skills in sketching are actually good.

Of course, what he usually draws are not characters or clothes, but he can also try it.

Just draw a couple outfit!
