The simulation continues.

[After he became a grandson, but you didn't feel happy, but a little sad and lost. 】

[Because, he brought back a few little sisters from the south, and even hid Jiaojiao in the prime minister's mansion; And, since then, he's gotten busier. 】

[But you quickly reacted, it is natural for a man to have four wives and four concubines, you should not be so jealous, you should be open-minded and brave to accept them. 】

[So, you cheered up, actively helped him deal with the affairs of the harem, and helped him take care of the business house, and did not play petty to make trouble for him. 】

[In the following time, the commercial bank became stronger and stronger, the stores were opened all over the Han Dynasty, the business was connected to the world, and the income was also rising, which can be called a daily profit. 】

"That's the right thing a smart woman does."

Seeing Chen Yuzhu's psychological reaction and change in thinking, Cao Cao nodded.

In any era, women must depend on men to survive.

Even if she is a royal princess who is high, she must obey the emperor's arrangement, and she cannot make her own decisions about marriage.

This is the law of the operation of the whole world, and the transition from a matrilineal society to a patrilineal society to the present day cannot be artificially broken.

And Chen Yuzhu is just an ordinary woman, even if she is smart, even if she will become a generation of virtuous queens in the future.

In the face of the general trend of the world, she has no choice but to obey.

As for rebellion, that's not what smart people do.

"But, then again, this firm is indeed a good thing to make a fortune!"

Looking at the branches of commercial banks all over the world, the daily profits are extremely considerable, and Cao Cao's eyes can't help but turn red.

It's like a living Pixiu, gathering the wealth of the world, and making profits every moment.

Wealth, that's a good thing.

With money, you can do a lot of things.

Bridges can be paved and roads can be built, people's livelihood can be improved, education can be established, and the army can be built.... Wait a minute.

In the hands of the ruler, one coin can play the effect of ten coins and 100 coins.

"It seems that after Bin'er's business house is established, we have to discuss with him and ask him to hand over part of the money he earned..."

"Anyway, in the future, the world will be handed over to him, isn't it natural to ask him for some money!"

Brushing his beard, Cao Cao instantly made a decision in his heart.

[At the end of the year, the firm carried out a year-end inventory, but there were many accounts, and you ordered people to calculate for a long time, but they could not settle all the accounts of the year. 】

[So, you have to ask him for help, and he will teach you a new way of calculating accounts and simple numbers '0, 1, 2, 3..., etc.'] 】

[With this new way of accounting and simple numbers, it only took you three days to settle all the accounts.] 】

[From the establishment of Yin in mid-March of the 14th year of Jian'an to the end of December at the end of the year, the total profit of the firm in only nine and a half months was as high as more than 24 million yuan. 】

[In the face of such a big profit, you were taken aback, and your breathing was three points heavier. But when he learned about it, his face did not change, and he instructed you to pay your taxes on time and hand them over to the treasury. 】

[You were very puzzled at first, according to the tithe tax rate, you need to pay a tax of 2.4 million yuan, as high as 10% of the total annual profit. 】

[But you have a clear mind, and you quickly figured out the reason, and readily agreed, and arranged for someone to pay a lot of taxes that should be paid. 】

"Hey, this kid is even proficient in arithmetic? What else would you not have? ”

Outside the picture, seeing this scene, Cao Cao was shocked again.

The way of arithmetic began in the Spring and Autumn Period and the Warring States Period, with 26 volumes of "Xu Shang Arithmetic", 16 volumes of "Du Zhong Arithmetic", and "Zhou Ji Sutra" and other works.

During the Qin and Han dynasties, there were also various generations of families who supplemented and revised it, and gradually developed and completed the current definitive version of the "Nine Chapters of Arithmetic".

It is broad and profound, all-encompassing, including the invention of numbers, number definitions, number applications, decimal system, addition, subtraction, multiplication and division systems, negative numbers, negative number definitions and addition, subtraction, multiplication and division systems, equations, systems of equations, equation solutions, estimation of pi, microrate, decimals, fractions, conic volume formulas, least common multiples... Wait a minute.

But it is obscure and difficult to understand, if there is no famous teacher to teach, I am afraid that I can't understand the book.

never thought that his grandson was still proficient in arithmetic, which really surprised Cao Cao.

"This kid is sensible, knows how to take the initiative to pay taxes, and does not evade taxes like other businessmen."

"But that's right, the world is his, so naturally we must maintain the order of the world and do a good job as an example in the industry!"

Thinking of this, Cao Cao was a little stunned, and soon understood the reason why Cao Bin did this.

"Tithes have two million and four thousand dollars... If there were a few more commercial houses like Bin'er, wouldn't the taxes that the imperial court could receive in a year be as high as tens of millions of dollars? ”

"The way of doing business is really magical!"

Having said that, Cao Cao still covets the business houses under Cao Bin's hands.

[Next, the commercial bank has entered a stage of rapid development, involving more and more industries. 】

[He continued to come up with various inventions, such as seawater salt drying method, blast furnace steelmaking method, cement production method, white sugar refining method... And so on, and then monetize these technologies and turn them into commodities that circulate all over the world. 】

[There is a seawater salt drying method, so that the price of salt from tens of dollars per catty to three dollars per catty, so that everyone in the world can afford to buy salt and eat salt. 】

[There is a white sugar refining method, so that the refined sugar can be present, the face is as white as snow, the cost is low, and it is widely welcomed by the people. 】

[There is a blast furnace steelmaking method, which greatly enhances the hardness and flexibility of the weapon, and you start a business with the military, and gradually upgrade the military's weapons and equipment. Although there are no profits, and there are even losses, you are happy. Because you know that when the army is better equipped, his chances of winning and surviving when he goes out to fight will be greatly improved. 】

[There is a cement production method, you have made low-cost but durable cement, he began to vigorously improve people's livelihood, pave bridges and roads, and cement can be used. 】

[The cement roads take Xudu as the center and extend to the whole world, bringing great convenience to transportation, improving the mobility and speed of the army, and also providing great convenience for the transportation of goods between commercial banks, which can be described as a lot of benefits. 】

[High-rise buildings are lined up in the suburbs of Xudu, and these new-style residences will be used to reward meritorious soldiers, which are widely praised by the soldiers. 】

[Not only that, but he also built the city with cement, replanned the capital city, and doubled its size. 】

[It can be said that under the changes of the two of you, the whole world is changing with each passing day. 】

[Time flickered, three years passed, came to Jian'an sixteenth year, news came from the north, Liangzhou rebelled, he was ordered to go to quell the rebellion, and once again embarked on the road of the expedition. 】

This time, it shows in more detail what has changed throughout the world.

"I see!"

Seeing this, Cao Cao couldn't help but suddenly realize.

The last time, when Sun Shangxiang was simulated, it also showed changes in this period of time.

But he didn't give a detailed experience, just a brush.

Therefore, Cao Cao saw it in the clouds, but he didn't know why.

It turned out that all this was done under the joint efforts of Cao Bin and Chen Yuzhu.

One person is in charge of government, and the other is engaged in business, stirring up the world.

"This woman really has some skills, and she actually takes care of a huge business house in an orderly manner."

"Women don't let their eyebrows go, and their faces are better than their children!"

Three years later, the firm has become a super-giant product that spans the world, has hundreds of branches, involves hundreds of industries, and employs tens of thousands of people.

Maintaining the operation of such a commercial bank and sorting out the relationships between people and things is by no means something that ordinary people can do.

But in Chen Yuzhu's hands, it seems to be easy and effortless.

Such an excellent performance really made Cao Cao look sideways and praised him.

"Compared with the two, Sun Shangxiang is not worth mentioning."

"That's right, if this woman is just a vase that doesn't matter, it is impossible for Bin'er to insist on making her the queen."

At this moment, Cao Cao had a clear understanding.
