"The new paper is good and cheap, once it is listed, hard yellow paper and bamboo paper must die! You can't see the money when you sell one by one, but if you buy one by all the people of Datang, the profit is quite terrifying. But with your small workshop can't meet the demand at all, so the first thing to do is to expand the scale of the workshop! ”

"Wouldn't that leak out the papermaking technology?" Princess Changle asked, and Li Shimin also nodded!

"Just use the assembly line to work!" Luo Tong introduced the whole process of assembly line operation to Li's father and daughter, and then said: "The core technology is in the hands of people who absolutely trust, and papermaking technology will naturally not be lost." In fact, this method of operation is suitable for any skill, take the crossbow as an example, the arm, bow, machine, and arrow are made by four people, and then the fifth person is combined. The other three of the first four people are ignorant, even if there is a leak, there is only one part, and although the fifth person is a combination, he doesn't know how to cast the parts, let alone the materials of the parts! In this way, the technology of the crossbow has always been in our hands. ”

Li Shimin laughed and said, "Not bad, not bad!" That's it for the rest of the day! You go on. ”

Luo Tong nodded: "It is our purpose to take it from the people and give it to the people!" I decided to build the Datang Library with 50% or 67%. ”

"Library?" Li Shimin and Princess Changle each frowned. Li Shimin felt a little depressed, he was second to none in the Tang Dynasty, but now in front of Luo Tong, he was like a three-year-old baby, this is not clear, that is not clear.

"Stinky boy, what's the library, tell me clearly!" Li Shimin felt a little faceless, and had the idea of pumping people.

Princess Changle smiled "poof", seeing her father's blushing appearance, she hurriedly covered her mouth and endured it.

Luo Tong 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. Scholars from poor families could not afford to buy books, so they could go to the library to borrow and transcribe them. ”

The expressions of Li Shimin and Princess Changle were completely shocked at the moment after Luo Tong expressed his meaning.

Princess Changle was shocked: "People who enter the library and are willing to copy books to learn must be students who love to learn. ”

"This library is amazing!" Li Shimin took a deep breath, his eyes flashed with sharp light, looked at Luo Tong, and said with emotion: "It's amazing, it's amazing!" I don't even know what to say about you kid, but it's so right to leave this papermaking to you. ”

"It's just an idea, and everything will only come true when the money comes out. With money, start with Chang'an, and then Luoyang......"

"It's too slow!" Li Shimin had regained his composure and said, "My Datang has a vast territory, and if you want to build libraries, you will have to build thousands of libraries in various places, states and prefectures combined!" In addition to practical books on engineering, medicine, agriculture, industry, and soldiers, there are about 2,000 books of all kinds, and a library has at least 100 copies. Not to mention whether papermaking can make profits, even if it is really profitable, when you buy land to build a museum, and set up a museum one by one, it will take twenty or thirty years to spread out in the country, and in these twenty or thirty years, how many talents have to be wasted. When he said this, his fingers kept tapping on the table, and after thinking for a long time, he looked at Luo Tong and said very frankly: "The idea of the library is very good!" But there can only be the imperial court to do it, you are wholeheartedly for the sake of the Tang Dynasty, how can I harm you and the descendants of Changle. ”

"Thank you father-in-law for your love, my son-in-law is wrong!" Luo Tong was dripping in cold sweat, and just this time, his underwear was soaked with sweat!

Once hundreds or thousands of libraries are opened, he is the Confucius and sage of the Tang Dynasty, and the prestige is not as good as the emperor. Li Shimin was vaguely telling Luo Tong that he could trust Luo Tong, but he couldn't guarantee that the heir of the Tang Dynasty would be like him, and he didn't let Luo Tong interfere in the library, which was actually the protection and love of Luo Tong.

Li Shimin smiled with relief: "You are my son-in-law apprentice, the same as my child!" It's business as usual. ”

Luo Tong said with a smile: "It is true that I can't do the Datang Library alone, although I don't have the ability to spread it all at once, but if the imperial court operates, I have a way to solve this problem." ”

Li Shimin said eagerly: "What way?" ”

Luo Daodao: "The value of the library is the books, not how luxurious and magnificent the house is!" After the chaos in the world, there are many ownerless mansions all over the country, which can be used with a little repair, and the bookshelves and tables are not libraries? Bookshelves and tables don't cost much either! The father-in-law only needs to issue a decree, and the library will bloom everywhere. ”

Li Shimin said excitedly: "I know you have a way!" After thinking about it, he said depressedly: "Hey, why didn't I think much of it, I let you catch up everywhere." ”

Luo Tong smiled: "There are libraries in the country, but the books need to be reasonably arranged, in my opinion, one hundred books at the state level; Fifteen books at the county level are enough, all kinds of books are counted as 2,000 volumes, 100 books at the state level can be borrowed by 200,000 people at the same time, and 30,000 books at the county level! No matter how you count it, there is only the leftover! I provided the books to cover the taxes! Gotta give me some respite, though. ”

Li Shimin was shocked: "I know that you want to share my worries, but the whole country has spread out, how many books do you get!" Then you must not die? ”

"It's really difficult in the short term, but after meeting the needs of the imperial court, I started to make money. But it takes time to build a workshop, make paper, print books, and bind books! ”

Princess Changle interjected: "Brother Luo Tong has thought about it, even if there is paper, but paper can't produce knowledge after all!" No amount of paper you have, you can't make so many books. ”

Li Shimin nodded and said, "Changle is right. ”

Luo Channel: "Printing, it is indeed a bit troublesome, but it is not impossible to solve. I borrowed my father-in-law's seal. Seeing Li Shimin nodding, he took two seals, printed them on the paper once, and then reversed the order and printed them again.

Finally, he handed the two printed 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. If it is made of metal and becomes a metal type, it can be used for at least ten years. ”

"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 Luo Tong say this, how could Li Shimin and Changle not understand it, and they were even more ecstatic.

"I need the young superintendent to do these letters. The Shaofu supervisors are top-notch, and the characters they produce are correct in order to circulate in the world. "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.

"That's right." Li Shimin said: "I'll give you a holy decree, you can let them do whatever you want." ”

"Thank you, father-in-law!" Luo Tong saluted and said, "I will borrow Changle for a few days." ”

"Uh......" Li Shimin was stunned, puzzled and vigilant: "What do you want Changle to do?" ”

"I'm going to teach her a boxing technique! This set of boxing methods is both internal and external, integrating practicality and health preservation, suitable for men, women and children. The amount of exercise is small and the effect is large, and it is the treasure of Taoism to nourish life. When she learns it, she can promote it in the palace, and Yaochi and Zheng Liwan also learn together. ”

"Accurate!"

Luo informed Li Shimin that he was in a hurry, and he didn't waste time, so he went to the Shaofu Prison and told a group of craftsmen the principle of movable type printing, and asked them to make movable type molds. Then I ran non-stop to Wannian County, please recruit craftsmen in Wannian County, be sure to expand the papermaking workshop into a workshop that can accommodate more than 2,000 people in the shortest possible time, and then build a two-horse lane from the county to the workshop area, and at the same time hire papermaking experts to advertise out, now it is the agricultural season, manpower is everywhere, the county order is also happy to see the people under the rule of more income, Luo Tong will convene the county officials as soon as he leaves, so that everyone will take Luo Tong's requirements as the top priority to grasp!

After leaving the county office, Luo Tong threw a thousand silver cakes to Li Chen, and put him in charge of supervising the work, paying the wages, and in addition, he was also responsible for the purchase of papermaking raw materials.

Li Chen is Changle's housekeeper, ability and loyalty are not a problem, and he will follow all the orders of the future head of the family, and ask loyal and reliable people as assistants, so that they can run all the sugar workshops in Chang'an and collect bagasse. Bagasse is a useless waste product in the hands of sugar workshops, and some people use money to collect it, so naturally no one refuses.

As for the horse lotus grass everywhere, it is easy to pick. Only bamboo is more troublesome, but in ancient times, the land was vast and sparsely populated, and bamboo grew quickly, so it can still be prepared for felling and acquisition.

In the end, he met with Shi Zhiguo, emphasizing the importance of technology, and asked him to follow the assembly line operation in the future, and his main task now is to bring out the more than 50 craftsmen in front of him, so that they can master the various processes as the core figures in the workshop in the future. Just in case, Luo Tong also made a confidentiality agreement with these 57 people, and took away their family information as a safeguard.

The seeds have been sown and are waiting to blossom and bear fruit.
