Chapter 781: Cao Cao Learns Mathematics

After some understanding, Yuan Shao realized how thorough Zhang Yu was.

It is estimated that Zhang Yu collected more than 300 million yuan of wealth in Xiapi City.

At this time, Yuan Shao gave relief to the aristocratic families and promised to help them restore some of their strength. The Yuan family formed an alliance with these aristocratic families, which made Yuan Shao's governance in Xuzhou much easier.

This matter had a great impact, and Zhang Yu was naturally punished by the aristocratic family again.

However, with the skyrocketing population, the proportion of aristocratic families has been decreasing. Although their influence is still great, they have gradually lost their influence in some places where aristocratic families have been suppressed.

Another thing that surprised Zhang Yu happened.

The thing is like this, Zhang Yu swept up the aristocratic families in Xiapi City, confiscated all their properties, and even confiscated their land deeds and house deeds.

These aristocratic families were wiped out by Zhang Yu, but some people managed to keep half of their property.

It turns out that this aristocratic family has business dealings with Jiangdong and Youzhou, and has just received a large sum of money.

The most important thing is that the payment for the goods was received by bank notes, and the head of the aristocratic family brought it with him.

Zhang Yu and the others will not search the body when they search the family property.

No body search is to avoid physical conflict between soldiers and others, resulting in unnecessary bloodshed, and it is to protect women from making mistakes.

In this way, the aristocratic family kept half of the family property, and started business immediately after Zhang Yu and the others left.

You must know that Xiapi City is now a blank period, and it will take time for the various families to mobilize resources from other places, but he doesn't need to use bank notes directly.

This aristocratic family was blessed by misfortune and achieved great development. While other aristocratic families did not recover, they actively seized the market.

In the end, the strength of their aristocratic family skyrocketed several times.

It was a legendary wealth story that soon spread among the families.

The result of this incident is not only that family but also Zhang Yu.

A few months later, a round of great development broke out in the bank, and various merchant families deposited hundreds of millions of money.

After the big money reaches the bank account,

As long as the bank issues bank notes, Zhang Yu can use the money as he pleases.

Of course, Zhang Yu will not let the bank be in crisis, and will not use all of it. He will reserve a part of the bank for emergency use, and he can use a large part of the big money.

This is simply a surprise, no one expected such a thing to happen.

Of course, these things only slowly affect after a few months.

After Zhang Yu withdrew from Xiapi City, his march was relatively slow, but Yuan Jun did not pursue them. It took more than ten days for them to safely enter Guangling County.

Guangling County has garrisoned 200,000 troops.

Not much happened elsewhere in the past few months after the attack on Lu Bu.

Sun Ce did not move. Although he really wanted to attack Jiangdong and take advantage of the opportunity, Zhang Yu had deployed many troops on the Yangtze River. He had no chance, and he was even more afraid that Zhang Yu would abandon Xuzhou and attack him instead.

Yuan Shu took the opportunity to recuperate for a few months, allowing him to recover a little bit of strength.

Yuan Shu's soldiers and horses have also undergone rectification and training, and he has also accumulated some family assets, but this time in the Xuzhou War, he knew his own situation, so he didn't move his mind at all.

Besides Cao Cao, after going back, the undercurrent surged, especially Zhang Xiu and Li Jue were very unstable.

Cao Cao also killed a group of aristocratic families, which calmed down the scene.

Cao Cao's loss this time was too miserable. In the later stage, he could only watch Yuan Shao and Zhang Yu compete for Xuzhou.

Yuan Shao also snatched all the territory he managed to gain before, and he didn't get any territory in Xuzhou.

The biggest loser in this battle is Lu Bu, and then Cao Cao.

The winners were naturally Zhang Yu and Yuan Shao. Yuan Shao got a lot of land, and although Zhang Yu had less land, he made a lot of money and took the opportunity to expand his influence.

There was no major movement among the princes in other places. Although small movements continued, nothing major happened yet.

There is another person who has a great interest in this incident, and that is Cao Ang.

Cao Cao fell ill when he went back, very serious.

After Cao Ang returned, he was reused by Cao Cao. When Cao Cao was unable to manage affairs, his subordinates were all around Cao Ang.

However, Cao Ang's ability is also very high, and he handles all things very well, which makes Cao Cao very relieved.

Cao Ang has been busy for two months and handled the matter at hand very well.

In the past two months, Cao Cao has recovered a lot and has started to deal with things, but many things are still in charge of Cao Ang.

Cao Ang is personally grasping a few things.

On this day, he came to Cao Cao after receiving the news that Zhang Yu was returning to Jiangdong.

"Father, you are feeling better." Cao Ang entered Cao Cao's study and saw Cao Cao reading a book.

"Ang'er is here. He is always old, but he can still last for a few years." Cao Cao pointed to the seat next to him and said, "Sit over there."

Cao Ang sat down at the side, Cao Cao took a few books, and said: "These are the Jiangdong textbooks you brought back. I read a few of them, and I have to say that this mathematics is a magical book. The calculations in it Methods, statistical methods, can intuitively respond to many problems, and these geography, physics and other things are really amazing, and some of them can be directly applied in the military.”

When Cao Ang came back, he naturally brought back a lot of books. These books are for public sale, but for many things such as mathematics and physics, it is useless to bring back books that no one taught you.

If Cao Ang hadn't studied there for more than a year, I'm afraid he wouldn't understand.

"Father, Zhang Yu attaches great importance to mathematics. Mathematics is a must for everyone. He has also organized dozens of people who are proficient in mathematics to study new topics. I have seen that the application of mathematics to statistics in various fields has very good results. In addition, Zhang Yu is building a new city, and the geometry and statistics in it make the city more efficient and less expensive."

Cao Ang briefly explained what he saw.

Cao Cao learned mathematics for more than ten days, and found that many things can be applied in practice, which is very easy to use.

Not to mention anything else, the things he made Cao Ang's statistics are very intuitive, making it easy to make decisions.

Cao Ang could even make a report, which Cao Cao, who had never studied mathematics, could understand at a glance, and he could make a decision within a few minutes.

Therefore, Cao Cao also began to study mathematics.

However, Cao Ang could only teach him a little bit of his mathematics knowledge, and he didn't understand a lot of books.

But Cao Cao likes reading and researching.

After putting down the books, Cao Cao said, "Zhang Yu is going to take a scientific examination soon. This scientific examination is definitely an epoch-making thing. He is the only one who can think of it, and he is the only one who dares to do it."

"Father, after the development of our academy, there are more than 300 students at this time. My son wants to expand the scope and establish several elementary colleges, like Jiangdong, to train more talents. Many things need to be learned from childhood. It's very laborious." Cao Ang said.

"Let's do it, but you have to find me a math teacher. You have a lot of things to do, so you can't always teach me." Cao Cao said.
