Guo Jia also followed, still wanting to see how those books were made first.

"Ziang, where are you going to take us", Xi Zhicai asked, Liu Yi's yard is not small, and he hasn't arrived after walking for a long time.

"Of course it's in the backyard, where else can I put it, it's almost there, don't worry", Liu Yi ignored Xi Zhicai's anxiety and continued to walk forward.

"Hehe, this is the third time you've said it's almost there", Guo Jia took a sip of wine, burped, and said with a smile.

After walking for a while, I arrived at the backyard of Liu Yi's house.

"It's here, come with me", Liu Yi said.

Guo Jia and Jia Xu followed closely and walked in, and Liu Yi made a mysterious and mysterious way, arousing their curiosity.

When you enter the backyard, there are no flowers and plants, and the scenery is not beautiful, only a small pond in the middle, and there are cut bamboos left there.

"Ziang, your backyard is really broken", Guo Jia laughed, very interested in Liu Yi's backyard, unique.

"Hehe", it's not to get those books, see that the pool is not, that's where the paper comes from.

Liu Yi led them to the front of the pool and motioned for them to look over.

"The paper is made of these yellowed bamboos, Ziang, you didn't lie to us", Xi Zhicai looked at Liu Yi suspiciously, how could something as hard as bamboo become soft paper, Xi Zhicai couldn't believe it.

Guo Jia also looked like he was watching a play, and he didn't believe it very much, how could bamboo become paper, such a precious thing as rice paper was really made of bamboo.

"Our paper is indeed made of bamboo, don't you pay attention to the color of the paper, it is a little yellow, that is, the bamboo soaked in water for too long", Liu Yi explained, papermaking is indeed magical, otherwise it would not be listed as one of China's four major inventions.

"Just soak it and turn it into paper?" , Xi Zhicai hurriedly asked, if the process is so simple, rapid mass production can quickly open the academy.

"How can it be so simple, this is only the first step, there are several steps after soaking bamboo, it is more time-consuming", Liu Yi smiled and shook his head, without that kind of mechanical equipment, the most traditional papermaking technology is very time-consuming.

"Ziang is really talented, I would never think of this thing", Jia Xu said with emotion, people are old, conservative in thinking, and drink tea when they have time, they will never think about this aspect, and they also admire Liu Yi for these bells and whistles all day long, people can really make it, and he is also a talent.

"There is a certain opportunity, let's go, let you see how those same books came about", Liu Yi did not refute, of course there is an opportunity, and crossing is not the biggest opportunity? Otherwise, how could he have papermaking and printing, he couldn't think of it even if he wanted to break his head, this is not an era at all, when papermaking didn't come out, printing would definitely not come out.

"Okay, go and see the magical printing technology you said", Jia Xu followed with a smile, becoming more and more interested in Liu Yi's backyard.

Walking into Liu Yi's small invention house, Guo Jia looked left and right curiously, but he didn't expect Liu Yi to have such a room.

Liu Yi picked up something in a cube and handed it over for them to observe.

"This is? Zigzag? But how can it be the opposite", Guo Jia picked up the thing in the cube, saw that there was a word on it, and said unconvinced.

"It's indeed a word, it's right to do it the other way around, all the words in that book are here, and they are arranged and printed with these words", Liu Yi simply described, it was really easy to directly steal the crystallization of ancient wisdom, otherwise he would not have thought of it at all.

"That's how it came, it's amazing", Jia Xu reacted, although Liu Yi's description was very abstract, but after seeing these reversed words, seeing those books with exactly the same font, Jia Xu instantly realized that it was not written by people, or printed with these words, and the reason why it was reversed was to print it positively.

"Okay, well, with these two technologies, there is no boundary between the Hanmen and the family anymore", Xi Zhicai laughed with the words.

The existence of papermaking and printing technology makes knowledge not something that can only be mastered by the family, and with these books printed, it is completely possible to exchange bamboo slips with the family, even if it is two books for one volume, it is also earned.

"Ziang, we can also take the bamboo slips of the family and print them, and use some of the cost as the transfer management, so that the library can be more abundant", Xi Zhicai couldn't help but suggest, the family has too much knowledge in their hands, and Xi Zhicai has always wanted to get their knowledge, and today finally has a chance.

"It's true, but some planning is needed, I want to take advantage of the construction of the academy to promote books and other things, and use books to exchange with the family for the right to use bamboo slips or borrow them", Liu Yi said with a smile, many knowledge books are unique, and the family also wants to master more knowledge, and they must be willing to exchange them.

"Yes, but how can we publicize it", Xi Zhicai lowered his head and pondered, it is not so easy to get the family to voluntarily hand over the bamboo slips for them to print, at least let the people of the world know that Qingzhou has book knowledge to exchange.

"I have an idea", Jia Xu said with a smile, and it is actually quite easy to let the world know.

"What is Wenhe's clever plan", Guo Jia looked up at Jia Xu, he hadn't come up with a good way yet, Jia Xu's reaction speed was so fast.

"I think Xuandegong's birthday should come", Jia Xu smiled and said something inexplicable, so he didn't say anything, and looked at the others with a smile on his face.

"Seconds, Xuande Gong is now a prince all the way, and he is the first person to awaken the emperor star, if he invites the world on his birthday, he may be able to successfully push out the book in one fell swoop", Guo Jia praised, although Jia Xu did not finish his words, the meaning was obvious, and Guo Jia quickly figured it out.

"Yes, yes, Wenhe's idea is feasible, Qingzhou is not afraid of other people's prying eyes, just to show our strength, the construction and development of the academy also needs teachers, it would be good if we could attract one or two famous teachers", Liu Yi said with a smile, agreeing with Jia Xu's idea.

"Let's go, go to Xuande Gong, Xuande Gong's birthday has to inform him, otherwise we won't be able to hold it", Liu Yi proposed with a smile, to celebrate Liu Bei's birthday, although Liu Bei is still quite young, but this is not the point, people in the world don't care about Liu Bei's age, what they want is an excuse to visit Qingzhou openly and understand the enemy's situation.

Guo Jia Xi Zhicai and the others looked at each other and smiled, Liu Bei's birthday was decided like this, it's really funny to think about it, anyway, it's Jia Xu Liu Yi's idea, let them worry about it, Guo Jia thinks it's good to watch the play, and it should be very interesting to see Liu Bei's reaction.

Liu Yi and Jia Xu walked in front, discussing what to say in the waiting meeting, the final result was that Liu Yi brought up this matter, Jia Xu's reason was very strong, he had already proposed the beginning of this matter, Liu Yi had not contributed much, it should be Liu Yi to say, Liu Yi was stunned and couldn't refute it, people only talked about this matter, he had no choice but to agree.

Soon arrived at Liu Bei's mansion, Liu Yi glanced at the three people behind him with a smile on their faces, and patted his head helplessly, he was still too young, and he had to assign the work well in the future, and he couldn't always let them watch the show.

Walking into Liu Bei's courtyard, I saw that Liu Bei was looking down at government affairs, and I didn't know what he was doing.

"Xuande Gong, there is something looking for you", Liu Yi said with a smile, his expression made people know that there was a ghost at a glance.

"What's the matter", Liu Bei asked suspiciously, seeing the four of them come together.

"Xuande Gong, we think your birthday is coming", Liu Yi said stubbornly.
