"Not counting the people of Fengzhu and the palace, the number is really small!"

After the brother-in-law left with a set of books, Li Yuanjia secretly calculated: "The prince doesn't seem to be interested in it, and King Wei's words seem to be alive, plus this house is loved...... Alas, too little! ”

Thinking that these people still don't know if they will really attach importance to the existence of mathematics, Li Yuanjia felt a lot of heartache.

In Datang to promote Arabic numerals and related mathematics only, he was serious.

Crossing into a prince of the Tang Dynasty, and he was also the prince of the Tang Dynasty during the Zhenguan period, he himself had already given up on the idea of being a big man in the future. After all, Li Shimin is eloquent and strategic, and Tang Gaozong, who can play to death his uncle and eldest grandson Wuji, is not easy to mess with, and then Wu Zetian killed the Li clan, which makes people feel cautious and panicked......

Anyway, no matter how you calculate it, Li Yuanjia doesn't feel that he has the soil to play in politics and military.

Besides, he doesn't have the ability to do it.

Playing politics is about talent, Li Yuanjia doesn't think that he has the qualifications to mix officialdom after being a little doctor all his life in his previous life, so even if Datang is not so wary of princes, he will not plunge headlong into this circle with no future. As for the military, it is even more nonsense, Li Yuanjia didn't even dare to carry a brick, let alone take thousands of troops and horses to fight.

So come to think of it, all he can do is the economy, technology and culture.

Among them, making money should be the easiest.

After all, those things in the head, you can make money by taking out some of them, such as thirteen incense and solitaire are very typical examples. And with the identity of the Prince of the Tang Dynasty, it is estimated that many people will be happy to see Li Yuanjia do that businessman's business. Even Emperor Li Shimin may be dissatisfied because of the face of the imperial family, but he will not punish his younger brother for this.

But unfortunately, making money is also the least interesting thing for Li Yuanjia.

This is actually very easy to understand, after all, no matter which one you are, you have become the prince of Zhengyipin when you are very young, you have tens of thousands of acres of land and a warehouse of money, and every year there is a fortune that can make the whole family live comfortably, I am afraid that you will have no concept of money. Especially Li Yuanjia's future descendants will have titles and fortunes, so there is no need to worry about them.

So all along, Li Yuanjia's purpose in doing business is not purely for money.

First, he is not particularly interested in money, and secondly, countless historical facts tell him that being too rich in this evil feudal society is not necessarily a good thing, especially when you have the ability to really be rich and rival the country, it is extremely important to control your desire to make money......

So when you think about it, the rest seems to be culture and technology.

Li Yuanjia, who doesn't want to spend his life doing nothing, actually wants to leave a strong mark in Chinese history. There is no doubt that both culture and technology are definitely more promising than being a virtuous king, or being a super-rich man.

Then, without much hesitation, he ruled out culture again.

Being a copyist is the easiest, because Li Yuanjia does have countless ancient poems in his head; However, being a great writer is also the most difficult, because when your literary accomplishment is limited to the poems in your memory, in this era, you are actually a war scumbag, and you may be exposed anytime and anywhere.

No writer only writes poetry and doesn't have to do anything else.

For example, in the most popular drinking order in the Tang Dynasty, Li Yuanjia had seen it a few times, and he was really a talent, not only to be able to write poems in response to the situation, but also to know every sentence and every word in the poem. If you are like Fang Xuanling and Wei Zheng, you still have to be able to write articles, and a small thing can pile up countless gorgeous words!

can only write poems to be a writer, that is purely a plot only in a dream.

So......

God seems to have the only way to be a scientist in front of Li Yuanjia.

Whether it is mathematics, physics and chemistry, or his old profession of medicine in his previous life, Li Yuanjia has knowledge beyond this era, and any little bit of it may be able to change the historical course of this discipline. Let's take this Arabic numeral...... No, it should be called Indian numbers now, and that's how it exists.

Mathematics is the foundation of all science.

That's why Li Yuanjia wrote dozens of mathematics books, and spent several years carefully compiling six of the most basic textbooks, hoping to make great strides forward in Chinese mathematics - although most of the knowledge in it has been mastered in the Tang Dynasty, it is undeniable that the use of Arabic numerals will make mathematics intuitive, and the summary of various formulas will also make mathematics "simple"!

Can the best tools, combined with the ingenuity of ancient mathematicians, make Chinese mathematics develop by leaps and bounds for hundreds of years?

These are all things that Li Yuanjia is looking forward to.

And not only the subject of mathematics, but also the knowledge of physics and chemistry that future junior high school students understand, combined with mathematics, the mother of science, what kind of sparks can be produced in ancient China?

When you have nothing to do, you can choose whichever I choose, Li Yuanjia is so excited that he can't sleep at night!

However, looking at the reaction of the crown prince, the king of Wei and Fang Yiai after they got the six books, Li Yuanjia couldn't help but be disappointed in his heart - the most valuable wealth in the world was in front of them, and their performance was difficult to satisfy Li Yuanjia. Even if Li Tai seems to be interested, there is still a big gap between him and Li Yuanjia's expectations......

"King, Wang Pu asks to see!"

At this time, Chunyan walked into the house lightly and asked in a low voice, "Do you want him to wait outside now, or come in now?" ”

"Wang Pu? Let him in! ”

After being stunned for a moment, Li Yuanjia came back to his senses and nodded.

After cleaning up his mood, after Wang Pu walked in and saluted, Li Yuanjia smiled warmly: "Wang Pu, do you know everything about Xinhua Bookstore?" ”

"Yes, King."

After clicking on the picture, Wang Pu said with an excited expression: "The white paper of our palace was sold out almost as soon as it was delivered, and now there are still many people who want to book it...... Lord, do you think we should recruit more people to help? ”

"Oh? Do you feel the need? ”

"Of course you need to, the more the merrier!"

Taking a deep breath, Wang Pu's voice instantly became a lot higher-pitched: "Wang, according to the situation in the bookstore, even if we sell one for thirty yuan, we can sell at least thirty or fifty thousand copies every month, and our current manpower is far from enough!" ”

The output target of Hanwangfu Paper Mill is only 10,000 pieces a month.

Wang Pu originally thought that this number was enough, but now after looking at the sales of Xinhua Bookstore, he realized how naïve his thoughts were! Chang'an City and Luoyang City, there are too many powerful and rich people in the two capitals of the Tang Dynasty, if you count the original rich merchants in the Western Regions......

10,000 a month, how can it be?!

Looking at Wang Pu's excited face, Li Yuanjia smiled slightly, waved his hand and said, "Okay, I understand your thoughts, but 10,000 sheets a month is enough, no more!" ”

"Huh? The King ......"

"Okay, this king has made up his mind, you don't have to say it!"

didn't give Wang Pu a chance to speak at all, Li Yuanjia raised his eyebrows and said: "Put aside the matter of blank paper first, and then you mainly do another thing for me, first print six books for me......"
