Datang: The prince of salted fish was overheard by Li Er

Li You smiled slightly, and said lightly: "It's as long as the empress likes it."

"Erchen established a paper-making workshop and a printing workshop in Shence Mansion, both of which are his own properties, and they don't need much money."

The queen smiled gratefully, Li You's books solved her urgent needs.

"King Chu, this gift of yours is really the best gift I have received today!"

Originally, Empress Changsun was a little worried that these wives from aristocratic families agreed to her face to face, but she didn't do anything.

Now with the first batch of [-] copies, the promotional activities can be launched quickly.

As soon as Empress Changsun said this, Li Chengqian, Gao Yang and the others immediately frowned again.

Li Chengqian never thought that the clown turned out to be himself.

Although Li Lizhi was a little depressed when compared to Li You, but when she turned her head and thought that her gift was also given by Li You, she happily continued to eat cakes with her eldest grandson Siyi.

On the other hand, Empress Changsun still had some doubts about these books, but at this time, the more important thing was to distribute books to these wives.

The wives picked up the book and were amazed again.

But there are too many things that surprised them today.

Whether it is the dreamlike perfume or the blissful cream cake, in their opinion, it is better than the paper of this printed book.

What the wives and queens overlooked, Li Shimin didn't know.

Li You brought a lot of books, and he picked up one casually.

As soon as he started the book, he noticed something unusual in it.

These papers are really good, and you can smell a faint fragrance when you get close.

Li Shimin turned the pages of the book with great interest, and there were neatly arranged words on the paper.

The printing of the characters is extremely clear, and it can be seen that its typography has reached the pinnacle level.

Li Shimin knew before that Li You built these two workshops in Shence Mansion.

But he didn't take it seriously, but he didn't expect that the finished product would be so good.

Li Shimin waved his hand, letting Li You lean over to speak.

[Hey, why did you find me again! 】

[Li Er, can't you keep labor and capital clean for a while! 】

Although he was dissatisfied, Li You could only walk over obediently.

Although Li Shimin was unhappy, he was quite pleased to see Li You coming over obediently.

"You'er, the printing workshop and papermaking workshop are both good. During this period of time, they have worked overtime to print so many books. They must have used a lot of craftsmen!"

"The artisans below will be rewarded with great rewards!"

Li Shimin still has old eyesight. Although "Health Care During Pregnancy" does not have many pages, he has not known the book for a long time from the queen.

To be able to print this book in such a short period of time and achieve such quality must have hired a lot of engraving craftsmen.

"Thank you, Father!"

Li You thanked him respectfully, then walked to the side and stood up.

[Hey, Li Er is a bumpkin again! 】

[The movable type printing that my printing factory can use is not to engrave a page according to the content of the book pages, but to arrange them according to the content of the pages in a special plate box. 】

[In this way, there is no need for many master sculptors, and it is only necessary to invite five more literate guys to arrange the boards. 】

[And my high-speed printing machine, [-] copies, is only half an hour. 】

[In this half an hour, there is still a lot of time for modulating the machine.When batch printing starts, [-] copies per hour will do! 】

[If Li Er knew that it has only been three days since I got this book, I guess Li Er would explode on the spot! 】

"what!"

Sure enough, after hearing this voice, Li Shimin was not calm anymore.

In order to hide his excitement just now, he asked, "You'er, when did you get the Queen's book?"

Regarding this question, Li You hesitated.

Although he deliberately concealed it, he suddenly remembered Baiqisi's unpredictable reconnaissance ability before, and finally decided to get out completely.

Anyway, he has Liu Ji under his command now, so it would be nice to leave these things to him in the future.

"Going back to Emperor Father, three days. The time is indeed a bit rushed, or I can print more!"

Although Li You decided to speak out, he still held back.

On the other hand, Li Shimin's complexion is not so good at the moment.

'This bastard really didn't tell the truth. Didn't he just say in his heart that it would be printed in half an hour! '

'And this kid said that only five people who could read and write were used to make the typesetting to complete the production of the printed version. That movable type printing technique is really terrifying! '

During the Tang Dynasty, the mainstream printing technique was woodblock printing.

That is, each page of the book content is carved with a piece of wood.

A set of books with a hundred or so pages will have a hundred or so engraving blocks.

Therefore, the engraving of woodblock printing takes a lot of manpower and material resources. In many cases, after a book is edited, it takes several years for the light engraving.

And if one word is wrong on the engraved plate, the entire plate will be invalidated.

In this way, the engraving time will be longer.

Finally, after these painstakingly carved engraving blocks are used up in one stage, the storage of the plates also takes up a lot of space, and the plates are often scrapped due to deformation, insects, and corrosion.

Of course, some people will use slate to engrave and print.

Compared with wooden boards, stone boards print better and are easier to preserve.

But carving on stone slabs is more difficult and takes longer.

This difficulty in printing is also the reason why Empress Changsun needs the assistance of wives from various aristocratic families when she wants to promote "Health Care During Pregnancy".

Li Shimin looked at the book in his hand. According to the normal method, the five people estimated that it would take nearly a year to complete the carving.

Now Li You can complete typesetting and printing in less than three days.

How can this kind of printing not shock Li Shimin!
Shocked and unbelievable, Li Shimin felt that it was time to break the can.

Instead of being shocked and making Li You complain in his heart, it is better to let the storm come more violently.

Li Shimin continued to ask: "Your, how much is the output of this paper in your character-making workshop?"

【how many?Saying it scares you to death.It can produce more than [-] tons a day. 】

[Equivalent to the current measurement method, a knife of paper is about three kilograms, so it can produce nearly seven thousand dollars a day. 】

hiss!
Li Shimin gasped again.

We must know that Datang's current paper is not only expensive, but also produced in a small amount.

Often after a wonderful article appears, the big families rush to circulate and copy it, which can make the supply of paper in the city exceed the demand and the price will rise sharply.

According to legend, after Zuo Si's "Sandu Fu" was written in the Jin Dynasty, many people copied it, and the price of Luoyang's paper increased accordingly.

From this, there is also an idiom such as Luoyang Zhigui.

But with the output of Li You's paper workshop, not to mention Chang'an, even the entire Gyeonggi region has no shortage of paper.

Moreover, Li Shimin only made a rough calculation, and he was even more surprised.

If these papers are sold at the current best paper price of two pennies a knife, then one day can earn [-] pennies.

Although I don't know how much Li You's cost is, but calculated according to the general papermaking, the daily net profit is [-] guan!

In this way, there will be at least 300 million guan in a year.

We must know that in the early years of Zhenguan, the annual tax revenue was only more than 200 million guan, not counting customs duties.

Li You is just a paper-making workshop in the Shence Mansion, and the profits are worth more than one year's tax of the Tang Dynasty.

Such a result made Li Shimin speechless in surprise.

What kind of fairy method did Li You use!
