It stands to reason that Xu Guangqi came from afar, and Yang Chengying, as the host, should entertain him.

Yang Chengying probed Xu Guangqi's tone several times through Sun Yuanhua.

The answer is, don't bother, thank you.

Xu Guangqi did not live in the place arranged for him by Yang Chengying, but lived with Fang Zhenru.

Yang Chengying visited several times, but was also politely rejected by the other party.

Now the "ten cares" are there, and the next visit should be "eleven checks".

After being rejected for the tenth time, Yang Chengying was also impatient.

"Okay! The old guy relies on the old and sells the old, so I won't give in. ”

Yang Chengying became angry, "From tomorrow onwards, I will never go to the old man who is stubborn to death." ”

"It's long overdue." Geng Zhongming shouted, "The first time the general went, his subordinates said that they shouldn't go. ”

Kong Youde and others also agreed.

In their eyes, Xu Guangqi, the old man, will only put on a stinky shelf, and he will ignore everyone when he sees him.

Yang Chengying thought about it for a while, and felt unwilling.

A sense of frustration haunted me.

"Okay! This old man doesn't think he's great, I don't have to look for him. ”

Yang Chengying instructed: "Prepare a lot of paper and pen for me, I want to write a book." ”

Geng Zhongming and the other guards glanced at each other and were taken aback.

"Writing a book?" Geng Zhongyu smiled, "The general can still write a book?" What book to write? ”

"Mathematics. No, one algebra, one geometry. ”

Yang Chengying said confidently, "I want to start from elementary school and write a set of textbooks. ”

"General, what is an elementary school?"

The guards looked confused.

A trace of embarrassment flashed in Yang Chengying's eyes, and he accidentally said the content of the afterlife.

"That is, students read from a very young age. When I was about thirteen years old, I moved from this school to another school to learn more advanced knowledge. ”

Yang Chengying racked his brains to explain.

These people just knew a few big words, and they couldn't understand the meaning of Yang Chengying's words.

They all looked at each other.

"Well, anyway, I'll write it now. Don't bother me if you're okay in the future, except for the female soldiers. ”

Yang Chengying couldn't explain, so he simply gave an order.

"Yes."

The guards understood, and straightened their backs.

Yang Chengying lost his temper here, but Xu Guangqi didn't buy it.

Sandwiched between the two, Sun Yuanhua and Mao Yuanyi were the most uncomfortable.

Especially Sun Yuanhua, the teacher was invited by him. The teacher did not wait to see Yang Chengying, who was actually in charge, and refused to give books such as geometric originals.

Seeing that Yang Chengying came to the door for the tenth time, he was still turned away.

He discussed with Mao Yuanyi and decided to visit Yang Chengying to ease the tense atmosphere.

Unexpectedly, as soon as they arrived outside the tent, they were stopped by Geng Zhongming.

"Two gentlemen, do you have something important to see the general?" Geng Zhongming asked.

How does this make them answer?

This kind of thing is not big or small.

Mao Yuanyi asked rhetorically: "What is the general doing?" ”

"I don't know what kind of textbook he is compiling, or what it is called."

Geng Zhongming scratched his head, "In short, the general has specially ordered that if there is no major event, there will be no such thing." ”

Does he really want to make a math textbook?

Mao Yuanyi and Sun Yuanhua glanced at each other and turned to leave.

Sun Yuanhua asked as he walked: "Brother Zhisheng, do you think the general is angry, or serious." ”

"I think it's serious."

Mao Yuanyi thought for a moment and continued: "The general's temperament, I don't know you yet, and he is resolute. He said that what he is doing now, he will definitely start immediately. ”

"That makes sense. He always said that he wanted the geometric original, just to use it as a reference. I don't think he's telling a lie, he's really doing it. ”

Sun Yuanhua said this, took Mao Yuanyi's hand and walked briskly towards the teacher's residence.

He wanted to tell the teacher about it.

However, Mao Yuanyi pulled him back: "No hurry. The gentleman did not know much about the general's talents. It's better to wait for the general to write it out and then show it to the gentleman. ”

"Wonderful." Sun Yuanhua struck with both palms.

The two hit it off and decided to hide it for the time being.

Yang Chengying said that he would do it, and first tried to recall elementary school mathematics. Then I found that I had forgotten everything and started anew.

The first part is to look at the picture and read the number.

Draw a circle with 1 written in Arabic numerals next to it instead of the traditional capital one.

By analogy, drawing two figures is the Arabic numeral 2.

The second part is addition and subtraction.

It is mainly the addition and subtraction of carry within twenty.

While writing, I also dialed the abacus. When I was young, I recalled the addition and subtraction of the abacus I learned.

After all, there are no calculators in this day and age.

Without the-for-tat confrontation between Yang Chengying and Xu Guangqi, Xintun returned to its previous appearance.

The days are like this, day after day in the ordinary.

The city walls grew taller and taller day by day, the crops were harvested, and the oxen and farmers were everywhere.

Every evening, you can see men and women returning home with smiles.

During this time, Xu Guangqi had been discussing the defense of Liaodong with Fang Zhenru, Sun Yuanhua and Mao Yuanyi.

Xu Guangqi was the most interested, without Yang Chengying's "commotion", he felt physically and mentally comfortable.

Fang Zhenru was also very interested. After so many months, he was overjoyed to finally have someone who could discuss the situation in Liaodong with him.

Sun Yuanhua and Mao Yuanyi were the most careless.

Among them, Sun Yuanhua is okay, after all, he is his own teacher.

Mao Yuanyi was completely absent-minded.

He thought to himself, without the general's command and dispatch, no matter how beautiful your writing on paper is, it will be about zero.

Everything seems to be calm here.

However, this calm did not last long.

Half a month after Xu Guangqi's arrival, Xu Guangqi decided to go out of the mountain.

plans to work with Fang Zhenru to inspect Xintun.

This is not Xu Guangqi playing the score.

In fact, the reason why Xu Guangqi came in person was that in addition to writing letters from his disciples, he was also appointed by the imperial court.

The imperial court appointed him as the right attendant of the Ministry of Rites, and looked forward to him, a highly respected talent, to go to Jinzhou to rectify the atmosphere.

In his view, the inspection of Xintun was reasonable.

Fang Zhenru was a little embarrassed: "If you don't call General Yang, after all, Xintun was built by him with painstaking efforts." ”

"You are the Liaodong Inspector, he is just a junior who has no official or position."

Xu Guangqi said with a straight face: "Today you are going to take out the style of the patrol and let the people of Jinzhou know about your existence." ”

Through this period of contact, Xu Guangqi has discovered that Fang Zhenru is a manufacturable material, and he is worthy of standing up for him.

Fang Zhenru still felt that it was inappropriate, so he said, "Let's notify it." ”

Xu Guangqi took out the edict, "There is a will of the imperial court, you can rest assured and boldly follow me." ”

As soon as the edict was taken out, Fang Zhenru's spirit was lifted.

Sun Yuanhua and Mao Yuanyi's faces changed greatly.

No wonder the teacher came in person, and he didn't come out of the door for half a month, but he was actually collecting information.

Sun Yuanhua secretly screamed in his heart: "Oh my God, I'm in trouble now." If the teacher deals with the general too much, there will be chaos in Jinzhou. ”

Mao Yuanyi was also thinking: "Sending a clear stream like Lord Xu to come here is the idea of Cui Chengxiu and others. ”

The two secretly sent someone to inform Yang Chengying on the one hand, and followed closely on the other.

Something happened, and they played the round as soon as possible.
