Du Ruhui and Fang Xuanling looked at each other, both of them were unparalleled wise and resourceful people in the world, and their ability to understand new things was not inferior to Li Shimin. The rare words in Du He's words that only existed in later generations made them a little confused, but as long as they contacted the upper and lower levels, they could guess a ** of ten, and they generally understood Du He's meaning, and their expressions were a little shocked.

Looking at the two of them with such expressions, Du He smiled to himself, feeling a little complacent, no matter how good Dad and Uncle Fang were in history, in the face of this advanced knowledge, they could only look like this, not talking, let them digest it by themselves.

Fang Du and the two were not idle, but they had come back to their senses in an instant and smiled at each other. Fang Xuanling said: "It turns out that the virtuous nephew is already aware of this matter, but we are too careful. However, the virtuous nephew has entered the official career, and according to the law of my Tang Dynasty, he cannot engage in business. Although this matter is big, in order not to be talked about, I still pay more attention. Just come up with ideas, don't get too involved. He didn't know Du He and got Li Shimin's secret permission, and he was worried that he would be too deeply involved, which would be detrimental to his future career, so he said this.

Du He didn't want to explain, but just nodded his head to show that he understood. What's more, he has never been too interested in money and things, if it weren't for the fact that this matter is related to the strength of the Tang Dynasty, with his surname, he would definitely not be so bothered in this matter.

Fang Xuanling said to Du Ruhui with some emotion: "Giving birth to a son should be like Du Qinglian, you and I have been thinking about how to give the Hanmen scholars a chance to get ahead all these years, but to no avail, but now I can't imagine that the dawn will appear on Ling Lang's body." ”

Du Ruhui was a little complacent and a little proud, but then said: "This matter is not so simple, at least from the current point of view, we have only taken a small step forward. Paper can't produce knowledge after all! ”

They didn't explain what they said, thinking that Du He didn't understand.

But he didn't know that at this moment, his heart was like a mirror, and he knew it clearly, but he didn't expect it, it turned out that Du Ruhui and Fang Xuanling were also his fellow travelers, and their minds were also supporting the scholars of the poor family, suppressing the big lords of the family, and letting the Tang Dynasty get rid of its dependence on the big lords of the family.

"Why don't you build a national library? The poor scholars couldn't afford to buy books, so they let them go to the library! Du He followed Du Ruhui's thoughts, paper can promote the exchange and development of culture, it is true that it cannot produce knowledge, but books can. I remember when I was in college in the later world, I was reluctant to buy books, and it was common to soak in the library to read books all day during the holidays.

"Library?" Fang Xuanling and Du Ruhui each frowned, and they also felt a little depressed, they were all well-known figures in the Tang Dynasty, but now they are like three-year-old babies in front of Du He, this is not clear, that is not clear.

"Stinky boy, what is the library, tell me clearly!" Du Ruhui felt a little faceless, and had the idea of pumping people.

Du He hurriedly explained, "It is an institution that collects, sorts out, and collects library materials for people to read and reference...... It's similar to Hongwenkan, the only difference is that Hongwenkan is forbidden for others to enter, while the library I'm talking about is open and open, and tables and mats are prepared in the library for students to borrow books and copy and read. This is equivalent to giving them a learning atmosphere and giving students the opportunity to study hard. ”

Fang Xuanling and Du Ruhui's expressions were completely shocked at the moment after Du He expressed his meaning.

Fang Xuanling shouted in a low voice: "If the imperial court is willing to spend money on this matter, it is very feasible!" ”

Du Ruhui also shouted: "Yes, people who are willing to copy books and learn must be students who love to learn, and giving them such an opportunity is tantamount to creating a diligent and studious talent for my Datang." ”

"That's a great plan!" Fang Xuanling's kind eyes flashed with sharp light, looked at Du He, and said with emotion: "It's amazing, it's amazing, Keming has a son like this, it's really enviable." Without further ado, why don't we enter the palace at once and make this matter known to Your Majesty? As he spoke, the man stood up.

"No hurry!" Du Ruhui had regained his composure and said: "My Datang has a vast territory, and if you want to build a library, you will have to build more than 100 libraries in various prefectures and prefectures, and there are about 1,000 copies of all kinds of related books, and hundreds of copies need to be printed. What a staggering number? Although my Datang has been under great rule in recent years, the money and materials stored in the treasury are not enough. Such a big thing, it should not be rushed! ”

Fang Xuanling listened to Du Ruhui point out the crux of the problem, his face changed slightly, he groaned slightly, and sat down again: "What Keming said is that I am anxious. ”

"You don't need to worry about money, I don't lack the cost of building a library." Fang Xuanling and Du Ruhui may not know, but Du Heyan may not know that a few months ago, after sweeping away Li Jiancheng's remnants, all the gold and silver hidden under the mansion were transported into the palace and handed over to Li Shimin by himself. With so much money, only a part of it needs to be withdrawn, which is enough to build a hundred libraries.

Fang Xuanling and Du Ruhui both looked at Du He in surprise.

Du He said: "It's hard to say about this, but it's enough to have money!" ”

Fang Xuanling and Du Ruhui also didn't ask, a few months ago, Du He used the army to deal with things, the people may not know, but they are the prime minister, how can they not know, but for this matter, Li Shimin didn't want to say more, and they didn't ask much about it.

Only Wei Zheng chattered, saying that he used troops without authorization, and the etiquette and law were not in line with anything. Li Shimin said angrily: "The flying horses have been abandoned for a long time, I want to practice their night combat ability, do I want to report to you too?" ”

Wei Zheng is no matter how good he is, and he can't beat Li Shimin in the face of this scene, and no one cares about this matter.

After a pause, Du He then said: "As for printing, it is indeed a little troublesome, but I have been studying printing recently, and I have an idea in my heart that it can avoid unnecessary troubles and be more practical than engraving printing. ”

Fang Xuanling, Du Ruhui, you look at me, and at the same time show a look of ecstasy, Du He's papermaking skills have given them a great surprise, at this moment, listening to him can still improve the printing technique, there is no doubt, just said in unison: "What do you think?" ”

"Actually, it's not difficult, it's just movable type printing!" As a history teacher, you can not know who Qin Shihuang is, but you can't know the four major inventions in Chinese history: papermaking, compass, gunpowder, and movable type printing.

For all the information of these four technologies, he remembered in his mind, and the papermaking technique was mainly Cai Lun's improvement method, so there were some deficiencies, but the movable type printing technology was clearly remembered in his mind was the movable type printing technology invented by Bi Sheng himself.

"The printing technique we use today is commonly known as woodblock printing, which uses a knife to carve a protruding reverse writing on a piece of wood, and then inks it and prints it onto paper. Every time a new book is printed, the boards have to be carved from scratch, which is very slow. If there is a mistake in engraving, it has to be engraved again, and the hard work can be imagined. And my idea is movable type printing, in fact, the reason is very simple, is to cut a printing board into hundreds of small wooden blocks, and then carve words on the wooden blocks, carve those commonly used words, when you need to use them, these small wooden blocks are combined with modules to print, after the printing is completed, you can separate, leave it until the next time, there is no need to print a page of paper you need to carve a template, time-consuming, laborious, costly, so not only greatly save time, but also save a lot of money. ”

The truth of movable type printing is actually very simple, listening to Du He's words, how could Fang Xuanling and Du Ruhui not understand it, and they were even more ecstatic.

The two prime ministers, whose faces did not change and their hearts did not beat, lost their cool many times in a row during this day.

"Erlang, quick, let's go to the palace, find the emperor, go to the Shaofu Supervisor to find a printer, and invent this movable type printing." Du Ruyan couldn't wait to pull Du He, and Fang Xuanling hurriedly followed behind.

The three of them came to the palace non-stop, saw Li Shimin and reported the matter to him.

Li Shimin, who had just made a "horse" and was resting in the Lizheng Palace, heard the good news, and was also moved and excited.

The Shaofu supervisor is in charge of all the affairs of the hundred crafts, and there are also experts in charge of engraving and printing.

Li Shimin called all the powers of command to Du He, and put him in charge of commanding all the members in charge of printing.

On the way to the palace, according to the memory in his mind, he has done a good job of dividing the work, responsible for the carving of the carving, and the frame of the frame.

Because it was an experiment, Duhe didn't make the project so big, but just asked the craftsman to make a small square module, and asked the craftsman to carve out one to nine, nine numbers.

Shaofujian's craftsman skills are top-notch in the entire Tang Dynasty, and the speed is extremely fast, and nine numbers similar to seals have been carved in less than half an hour, and the small module has also been completed later.

Du He first inlaid the seals on the module from one to nine, brushed them with ink and printed them on paper. Then he took out the seal from nine to one, printed it again, scrambled the seal again, printed it randomly, and finally handed the three pieces of paper to Li Shimin and said: "Father-in-law, you see, the general concept is like this. Although the project of making movable type in the early stage was larger, it was very convenient to typeset books later. This is a movable type that can be used over and over again. This is still woodcut, and if it is made of metal and becomes a metal type, it can be used for at least ten years. ”

At this time, the old craftsman who had been in the Shaofu for thirty years knelt down and bowed: "Your Majesty, General Du's creation of this movable type printing technique can be described as a great innovation that shocks the past and the present, and with this movable type printing technique, the printing speed will be a hundred times higher than before. He was so impressed that he burst into tears.

Li Shimin glanced at Du He deeply, and suddenly said: "The loyal general Du He stepped forward to listen to the order!" ”
