The person in charge of the workshop left some of the finished paper as samples, and sent the rest to Liu Yu.

Liu Yumei accepted all the papers.

And the craftsmen in the workshop also quickly received Liu Yu's reward, each of which was properly ten gold. Some of them will never earn so much gold in their lifetime.

Inspired by the sparkling gold, the craftsmen began to burst into great potential, and began to work on improvements.

Verbal rewards, there are absolutely no actual rewards that can make people burst into their potential.

The craftsmen rely on their own craftsmanship to eat, and they get practical benefits, so they don't have to give up.

At any given time, it is best to encourage others to move forward and work hard, and in the end it is the most primitive material reward. It was common no matter which dynasty it was.

Each craftsman was rewarded with ten gold, which was a big burden for the Shenwu Imperial Court, which was now using money everywhere. However, Liu Yu felt that the money was well spent. The paper that could be written became cheaper after improvement, and the Chinese civilization would make a huge leap forward.

This is a contribution to the whole of China, and Liu Yu will not look at that little bit of gold. At the same time, Liu Yu also thought of a way to make a lot of money.

Liu Yu returned to his imperial study with these papers, and hurriedly called the crown prince Liu Xuan over.

Liu Xuan, as the prince, Liu Yu thought that it was necessary to let him know that there was such a thing as paper.

After Liu Xuan got married, in addition to studying and practicing martial arts and observing national politics every day, he accompanied his wife and waited for his child to be born with great anticipation. Liu Xuan originally liked to be quiet, but now except for necessary things, he usually doesn't even go out of the gate of the Prince's East Palace, so he almost becomes an otaku.

Liu Xuan, an otaku, is better than the soil fat house of later generations.

Hearing that his emperor's father was summoned, Liu Xuan had to leave from his wife and reluctantly came to the imperial study.

After coming to the imperial study, Liu Xuan saw Liu Yu with a strong smile on his face, staring at the imperial table.

Liu Xuan hadn't seen Liu Yu have such a look for a long time, so he asked An Dao: "Erchen to see my father!" ”

"Xizhi, you're here! Come on, I'll show you a social weight! What a treasure. Liu Yu beckoned to Liu Xuan.

Liu Xuan is even more strange, Liu Yu, as the Son of Heaven, is rich all over the world, and he has never seen any precious treasures, and now he actually says that big treasures can get Liu Yu's exaggeration, it must be true.

Liu Xuan's curiosity was aroused, and he quickened his pace to get closer to Liu Yu.

When he arrived at the royal table, Liu Xuan saw a lot of snow-white things on the royal table.

"What is this?" Liu Xuan really hasn't seen it.

Liu Yu smiled and said, "This is paper!" Paper that can be written! ”

"Paper?" Liu Xuan can be regarded as having seen the world, he has seen Cai Hou paper before, but he is not so white.

Liu Yu understood that Liu Xuan had never seen it, so he said, "Write a few words on this paper and take a look." ”

Liu Xuan was a little puzzled, he didn't believe that this thing could be written on it. But my father said so, so Liu Xuan had to do it.

When Liu Xuan picked up the brush and wrote the first word on the paper, Liu Xuan was shocked. This kind of paper can be used to write, and there will be no bamboo slips in the future.

"Father, where did this paper come from?" Liu Xuanqiang endured the excitement in his heart.

Liu Yu was very pleased, it seemed that Liu Xuan had thought of the usefulness of paper, and at the same time, he was even more satisfied that Liu Xuan could calmly ask for more information, and he knew that Liu Xuan's city government had grown a lot.

"This paper was secretly developed by my father many years ago." Liu Yu told the truth in front of his son.

"Father! She's a heavy weapon! Congratulations to the Emperor! The big man has his own God blessing! Father is wise! Liu Xuan didn't know what language to use to praise his father.

Liu Yu smiled: "Don't be in a hurry to praise your father. Father asks you, what can this paper do? ”

Liu Xuan arched his hand and said: "Father, with this kind of paper, then the use of bamboo slips will be greatly reduced, which is a great convenience for dealing with state affairs." I just don't know how much these papers cost? ”

"This kind of paper is too expensive to promote." Liu Yu put away his smile.

Liu Xuan was a little disappointed, if this is too expensive, it is still a good deal for bamboo slips.

Liu Yu looked at his somewhat lost son and laughed: "Xizhi, you are still a little lacking." This paper is expensive now, but it may not be in the future. ”

"Could this paper be improved?" Liu Xuan's brain is fast.

"That's right! I have ordered the craftsmen to improve it day and night to make the paper softer and cheaper. Liu Yu said: "At that time, the bamboo slips in the world will be eliminated!" ”

Liu Yu took out a scroll of books and asked, "Xizhi, who is in the hands of most of these scrolls?" ”

"This is a left-handed biography, and there will be some in the homes of the rich or the families of officials." Liu Xuan vaguely thought of something.

"That's right! Books are the best treasure in the world. However, most people today cannot afford to buy or read books. If I turned paper into a book and made it affordable for everyone in the Han Dynasty, what would the world be like? Liu Yu said inducingly.

"Then, the general trend of the world will change drastically!" Liu Xuan's mouth trembled when he thought that everyone had books to read.

"Yes! There's a book for everyone to read! Liu Yu remembered the prosperous era of later generations, where the people lived and worked in peace and contentment, everyone could study, and there were few illiterates in society, which was unimaginable now.

"Xizhi, my father will tell you about this matter today! I hope that after you succeed to the throne in the future, you must remember that if you can't realize that the people of the world can read and write in this life, future generations will take it as their own responsibility. Liu Yu told the purpose of calling Liu Xuan.

In this way, it is affirmed in disguise that Liu Xuan is the future son of heaven.

Liu Xuan nodded very seriously, he also hoped that he could do it.

After chatting for a while, Liu Yu asked Liu Xuan to go back.

After a while, Li Gui came to Liu Yu with a few wooden planks and said respectfully: "Your Majesty, these planks have been carved. ”

"Give me a try!" Liu Yu said with a smile.

What is the origin of these planks?

Many years ago, Liu Yu asked people to secretly develop paper, and at the same time, they also asked people to secretly develop printing technology. But without paper, no matter how capable the craftsmen were, they couldn't think of a reason.

In addition, Liu Yu is busy with state affairs, so he really doesn't have much time to care about this matter.

After the paper was ready, Liu Yu asked Li Gui to call a craftsman to carve the text on the wooden board to print the book.

This is both modulation printing.

Movable type printing became famous in later generations, but Liu Yu had only heard of it, and had never seen it at all, so now Liu Yu doesn't know how this movable type printing came about.

Books are hated less when they are used. Liu Yu deeply realized this point.

But there are always more solutions than problems, so Liu Yu thought of carving words on a wooden board and printing them on paper. This can also be used as a convenient printing technique.

The more Liu Yu thought about it, the more he felt that he was extremely smart, and he could think of such a solution.

Li Gui couldn't understand what Liu Yu wanted these planks for. It was the first time that the craftsmen had seen the words carved in reverse on the wooden board. Fortunately, the craftsmen in the palace are all awesome existences, and it didn't take long to carve the wooden planks ordered by Liu Yu.

Liu Yu took a pen and ink and gently smeared it on the carved wooden board. Then he gently pressed the board against the top of the paper.

Li Gui was stunned from the sidelines. Originally, this kind of rough work was done by Li Gui. Li Gui also automatically asked for help. But Liu Yu refused. Liu Yu wanted to try it himself.

Liu Yu also did this for the first time, and it was normal to fail.

Liu Yu's face was pity, it seemed that he himself was not a genius who knew everything.

"Your Majesty, what are you doing? Can you solve your questions? Li Gui was very puzzled.

Liu Yu regained his smile and said, "Zhong Yun, this is called printing, print the words on this paper, do you understand?" ”

Li Gui was at a loss. Let Li Gui think about how to harm people, he knows it, but he doesn't understand the other words.

Liu Yu knew that Li Gui didn't understand, he looked down at the paper he had printed, and sighed: "It seems that this still needs to be improved." ”

Li Gui also discovered that the ink on the paper that Liu Yu printed just now did not solidify, and it was still a very messy font.

"Zhong Yun, the progress of paper improvement should be monitored at all times, and at the same time, let the craftsmen study how to use wood to engrave and print, so that there will be no such situation. And this thing must be difficult to keep secret! Absolutely no one should know about it. Especially those craftsmen, I don't want them to give away anything! Liu Yu commanded.

This tone is what Li Gui wants most.

Li Gui nodded and said, "Your Majesty, the minister knows the importance of the matter, and there will definitely be no chaos." ”

Li Gui is very confident in this.

Liu Yu really hopes that these two things can succeed sooner, because there is a plan in his heart, a plan that can weaken Jiangdong and Yizhou.

After receiving Liu Yu's order, Li Gui supervised the craftsmen to work overtime to improve while also closely monitoring.

If anyone dares to talk nonsense outside, then the "shadow" spies will find him to have tea with the whole family.

Fortunately, the craftsmen are all people who do their duty, and they will not joke with the lives of their whole family. Besides, being able to get the reward of the Son of Heaven is already a blessing for the ancestors, and there will be no shortage of food and clothing in the future, where can I find such a good job?

Paper was not any success before. Now that there are successful samples, the craftsmen have a direction to continue to improve. Coupled with Liu Yu's golden words, as well as real rewards, the progress of the craftsmen is very fast.

In just ten days, the paper workshop was improved and a new batch of paper was made. Due to the improved process and the change of raw materials, the paper is much softer than last time.

The craftsmen were able to be so fast because of Liu Yu's investment in the workshop. The craftsmen are divided into several groups, each group has a different direction of improvement, and the results are also different, and finally in summing up, taking the essence and removing the dross. Of course, the resources consumed are also terrifying.

Big investment, and in the end it paid off greatly! Liu Yu held the softer paper, and he was excited.

The cost of this kind of paper is only 50 yuan, and it may be cheaper if it continues to be improved in the future.

As long as it is cheap enough so that people all over the world can afford it, then Liu Yu is already very content.

Liu Yu gave the craftsmen another reward at the moment, this time it was also ten gold per person! As long as you follow Liu Yu's wishes, there will be a lot of gold!

As soon as Li Gui heard that Liu Yu was going to reward him again, he felt distressed in his heart. Li Gui knows a lot, and now the imperial court is using money everywhere, and if Liu Yu spends it like this, it will be a huge burden.

Liu Yu didn't pay attention to money at all, he was rich in the world, as long as he thought it was worth spending, he would spend it.

Anyway, Li Gui can only complain about Liu Yu's spending in his heart, and the rest should be how it is.

This kind of paper can already allow Liu Yu to carry out his plan, and he immediately ordered the workshop to make such paper on a large scale, which is of great use.

Liu Yu gave Li Gui a part of the paper and asked him to take a craftsman who carved wooden boards as an experiment to overcome the problem between ink and paper.

There were no surprises, and the craftsmen finally overcame the problem of the ink solidifying quickly.

Craftsmen have found that if ordinary ink comes into contact with such paper, the ink is absorbed very quickly. The solution to such problems is specially made ink.

And the craftsmen really exerted their super strength to develop an ink. This ink allows the font to be printed on the paper while also remaining unabsorbed by the paper.

The only problem is that the ink will erode the board, and if it is used too much, the board will not be able to be used.

If the wooden board doesn't work, just continue carving, Liu Yu doesn't care about this.

With these two things, books can be produced in batches.

Books need a lot of samples to print. And Liu Yu didn't dare to say anything else, in his imperial study, there were the most books.

The books in the entire imperial study room have been accumulated by Liu Yu since he was young, and they are a huge cultural treasure. Now is the time for this treasure to exert its power.

These books are Liu Yu's treasures, and if others want to borrow them, Liu Yu won't give them.

Now that there is paper and ink, Liu Yu feels that it is more effective to preserve them by changing them to the appearance of books.

Liu Yu took out a few common scrolls from the imperial study, handed them to Li Gui, and ordered him to carve wooden boards according to the contents of the scripts and print them into books.

Li Gui didn't know how to do it at all, and he didn't even know what books were going on.

As a last resort, Liu Yu explained to him in detail what a book is.

Li Gui finally figured it out and stepped forward to run errands.

And all Liu Yu needed to do was wait, waiting for the craftsmen and Li Gui to make the book.
