After dealing with the follow-up of the outside remarks, Chen Zhou was free again.

On weekdays, he teaches Xun Qiao and Elk Zhen to learn mathematics, and Liu Ling and the others occasionally come to listen to the class.

Time passes quickly, and in a few days, the New Year is coming.

"Sir."

Xun Qiao trotted in happily, and said with a blushing face: "Sir, your book is finally ready." ”

In her hand, she still has a new book.

It was Chen Zhou and Xun Qiao who wrote the mathematics textbook, which was signed by them together, and the book was handed over to Cao Tai and them, and it was not easy to print.

Because many of the mathematical symbols on it, as well as some letters, etc., need to be re-prepared for the word block, which takes a long time.

Finally, before the New Year, it was printed.

"This is the husband's book?"

Cao Shan happily took it, and after looking at it for a while, she found that she couldn't understand it.

The other ladies looked at the math book, except for some relatively simple knowledge, and Cao Shan, they looked blinded.

"Show me."

Chen Zhou heard Xun Qiao's voice outside, and came out expectantly.

opened the math book brought by Xun Qiao, read it for a while, he closed the page with satisfaction, and said with a smile: "Qiao'er has done a good job, and in the future, Qiao'er's name will be famous for eternity." ”

The role of mathematics is still very large.

Chen Zhou will do his best to keep this mathematics book so that more people can learn it, and he is also preparing to open a mathematics course on the reconstructed Taixue.

This is one of the six arts of a gentleman, and when it is put on the table openly, no one will say anything.

"Mr.'s name is the one who will last for a hundred years."

Xun Qiao put the cover up and revealed their names.

The two of them, signed at the same time.

However, Chen Zhou's name is bigger, and according to the vocabulary Xun Qiao learned from Chen Zhou, the word "editor-in-chief" was added to the end of the name to highlight its importance.

"It's okay."

Chen Zhou smiled: "Hard work." ”

Qiao Ying stepped forward and said, "Qiao'er is not hard, in fact, she is not afraid of working hard for her husband, right?" ”

Hearing this, Xun Qiao lowered his head shyly.

This sentence said her careful thoughts.

Xun Qiao often came over, and he contacted Chen Zhou so frequently, just to be with Chen Zhou, and had no other meaning.

Lu Lingqi said: "Qiao'er has finished learning mathematics, will she come to us in the future?" ”

Hearing this, Xun Qiao also thought of this problem.

There is not enough reason to come back later.

Her pretty face was flushed, a little pale at this time, and she looked at Chen Zhou worriedly.

Chen Zhou said: "Qiao'er wants to come, you can come at any time, I don't have too many rules here." ”

"Thank you, sir."

Xun Qiao put all kinds of worries behind him and smiled sweetly.

As long as the gentleman still lets himself come, the rest is no longer important, and that is enough.

Chen Zhou looked at the math book brought by Xun Qiao for a while, made sure that there was nothing else that needed to be modified, and went out to inspect the factory.

In fact, the factory has long been standardized, Cao Tai and they are doing very well, and there is nothing to look at, this time out, Chen Zhou's main purpose is to care about the farm.

Basic necessities of life.

The aspect of food is still very important.

Eating meat is the guarantee of a strong army, and it is also one of the important means to enhance the people's sense of belonging to Cao Wei.

Whether or not they can produce cheap meat depends on whether those little piglets can grow up quickly.

When Cao Ang heard that Chen Zhou had arrived at the farm, he also came with him and handed over the factory to Cao Tai and Cao Fu to manage.

"Sir, these pigs grow up very fast!"

Dian Wei saw that he was a little piglet before, but now he is much older, a heavy big pig, and he doesn't know how thick the fat is.

Before being excavated and joining the army, Dian Wei often went to the mountains to hunt.

Wild boars are no less, according to his cognition, ordinary wild boars can't grow so fast in such a short period of time, and Mr.'s pig has broken the record.

"It's really fast."

Chen Zhou is very satisfied, it seems that they have been sterilized, and they can really grow fat in peace.

Pigs are also omnivores and eat everything.

Even in modern society, some poor rural families will build toilets on top of the pigsty, so that it is convenient for people to eat on top and pigs to eat below.

Sounds disgusting.

But it also shows that pigs are really easy to raise.

It's much easier to raise than sheep, dogs, etc., and it produces more meat.

"Pick the two biggest pigs and slaughter them tomorrow for meat."

Chen Zhou said again: "Gongzi can go back and tell the lord to gather all of them to be filial piety, and I will invite them to eat meat, preferably in Sikong Mansion, but I don't know if the lord will not agree." ”

After coming to the Three Kingdoms for so long, Chen Zhou has never eaten pig-killing rice.

The New Year is approaching, or make a pig-killing meal to regain the atmosphere and feeling of the past, and maybe you can bring this habit up during the Three Kingdoms period, and at the same time promote his pork.

Then bring the pig breeding technology to the people of the world.

Everyone eats meat together.

Even if you can't have meat at every meal, at least you can, eat one or two meals once in a while, and when the living conditions are better, the body will grow better, and people can be taller.

He also had a goal, which was to change the diet of the ancient people.

"As long as the gentleman proposes, my father will definitely agree, but can you really eat these pork?" Cao Ang asked.

They all know how bad pork is.

Although there are people who eat, there will not be many people who eat it.

Chen Zhou said confidently: "Of course you can eat, Gongzi can arrange it for me, just tomorrow, I will invite everyone to have a meal, this is called ...... Let's kill the pig! ”

This matter was quickly decided.

If they don't let them taste how delicious pork is, it is difficult to promote the development of pig farming.

"One more thing."

Chen Zhou said: "I heard that there is a place where there is a kind of rice, and the yield per mu is more than twice as high as the rice we usually grow. ”

"More than double!"

Cao Ang exclaimed.

In addition to growing wheat and millet, they also grow rice.

However, the yield per mu of these crops, without the blessing of chemical fertilizers, can produce two or three stones per mu is already considered a high yield.

Crops that are more than double the yield per mu of their current crops, if they really exist, it is a miracle that can change the Han.

"Excuse me, sir, where is that place? I'm going to get those seeds back! ”

Of course, Cao Ang understands how much benefit they have to when the grain production is high.

In ancient societies, food was the top priority.

Agriculture is the foundation of a dynasty.

Without food, they are nothing.

Chen Zhou said: "This kind of rice has relatively high water requirements, and it may not be suitable for planting in areas that are too north, but it is acceptable in Huaibei, Huainan, and northern Jingzhou." ”

Cao Ang thought about it quickly and said excitedly: "This is also very good!" If the production capacity per mu is more than doubled, we will plant near the Yangtze River and Huaishui, and the extra part of the grain produced will be enough for us as military food, and the rest will be left for the people to store grain, which is a great good! ”

There is still such good rice, they must get it.

Cao Ang said again: "Please tell me, sir, what kind of place is that!" ”

Chen Zhou turned around, looked south, and said, "This place is far away from Xudu, in the south of Jiaozhou, and the name of that place is Zhancheng. ”
