Yuan Shao learned how thorough Zhang Yu was.

It was visually observed that Zhang Yu had collected a fortune of more than 300 million yuan in Xiapi City.

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

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

However, with the explosion of population, the proportion of the family has been decreasing, and although the influence is still great, it has gradually lost its influence in some places where the family has been suppressed.

There was also something unexpected about this incident that surprised Zhang Yu.

Here's the thing, Zhang Yu swept the families in Xiapi City, confiscated all their property, and even collected their title deeds.

These families were swept away by Zhang Yu, but some people were lucky enough to keep half of their property.

It turned out that this family had business dealings with Jiangdong and Youzhou, and had just received a large amount of payment.

The most important thing is that the payment is collected with a silver ticket, and the head of the family carries it with him.

Zhang Yu: They don't search their bodies when they raid their property.

The non-body search is to avoid unnecessary bloodshed between soldiers and people, and it is to protect women from making mistakes.

In this way, the family kept half of the family property, and started business as soon as Zhang Yu and the others left.

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

This family has been blessed by misfortune and has achieved great development, and while other families have not recovered, they actively seize the market.

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

It was a legendary tale of wealth that soon spread among the Maison.

The result of this incident was 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 dollars.

After these big coins arrive at the account of the bank, the money bank only needs to issue a silver ticket, and then Zhang Yu can use the money at will.

Of course, Zhang Yu will not let the money bank have a crisis, he will not use it all, and leave a part of the money bank for emergency purposes, and he can call a large part of the big money.

It was nothing short of a bonus, and no one expected such a thing to happen.

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

After Zhang Yu retreated from Xiapi City, the march was relatively slow, but the Yuan army did not pursue, and they entered Guangling County safely after more than ten days.

Guangling County has 200,000 troops.

In the past few months of attacking Lu Bu, not much has happened elsewhere.

Sun Ce did not move, although he really wanted to attack Jiangdong and take the opportunity to gain benefits, but Zhang Yu arranged a lot of soldiers and horses on the Yangtze River, he had no chance, and he was even more afraid that Zhang Yu would give up Xuzhou and attack him instead.

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

Yuan Shu's soldiers and horses have also been rectified and trained, and he has also accumulated some family funds, but in this battle of Xuzhou, he knew his own situation, so he didn't move at all.

Besides, Cao Cao, after he went back, the undercurrent surged, especially Zhang Xiu and Li Dao's side was very unstable.

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

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

The territory he had fought hard before was also taken away by Yuan Shao, and he didn't get any territory in Xuzhou.

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

The winners are naturally Zhang Yu and Yuan Shao, Yuan Shao has gained a lot of territory, and although Zhang Yu's territory is small, he has made a lot of money, and he has taken the opportunity to expand his influence.

There was no major movement among the princes in other places, and although there were constant small movements, nothing major had happened.

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

Cao Cao fell ill when he went back, quite a serious kind.

After Cao Ang went back, he was reused by Cao Cao, and when Cao Cao couldn't be a director, his subordinates were all running errands around Cao Ang.

However, Cao Ang's ability is also very high, and everything is handled very well, which makes Cao Cao feel very relieved.

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

In the past two months, Cao Cao's body has recovered a lot and he has begun to deal with things, but many things are still entrusted to Cao Ang to be in charge.

Cao Ang is personally grasping a few things.

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

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

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

Cao Ang sat down on the side, Cao Cao took a few books, and then said: "These are the Jiangdong textbooks you brought back, I read a few, I have to say, this mathematics is a magical book, the calculation methods, statistical methods, can be very intuitive to reflect many problems, and these geography, physics and other things are really magical, some 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 there are many things such as mathematics and physics, and it is useless to bring back books without anyone teaching you.

If it weren't for Cao Ang studying 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, and he has organized dozens of proficient mathematics students who have been researching new topics. I've seen that mathematics is very effective in the statistics of various lines, and in addition, Zhang Yu is building a new city, in which geometry, statistics, etc. make the construction of the city more efficient and cheaper. ”

Cao Ang briefly said what he had seen.

Cao Cao studied mathematics for more than ten days, and found that many things can be applied to practice, which is very useful.

Not to mention anything else, what he asked Cao Ang to count was very intuitive and easy to make decisions.

Cao Ang can even make reports, which Cao Cao, who has never studied mathematics, can understand at a glance and make decisions in a few minutes.

Therefore, Cao Cao also began to study mathematics.

However, his mathematical knowledge can only be taught by Cao Ang little by little, and he doesn't understand a lot of books by himself.

However, Cao Cao likes to read and research.

Cao Cao put down the book and said: "Zhang Yu is about to take a scientific examination, this scientific examination is definitely an epoch-making thing, and he can think of it, and he dares to do it." ”

"Father, after the development of our academy, there are more than 300 students at this time, and the child wants to expand the scope and establish several elementary colleges, such as Jiangdong, to cultivate more talents, many things have to be learned from a young age, and it will be very laborious when he grows up." Cao Ang said.

"Go ahead, but you're going to find me a math teacher, you have a lot of things, and you can't always teach me." Cao Cao said.
