"Shiro, is our world really round?" Xu Miao blinked her eyes of curiosity.

"Of course it's round, when you see the tengu eating the moon, that black shadow is round, so no matter which way I go, I will eventually return to you!" Xiao Yao sent an earthy love story.

"Stinky pervert, can you really take us into the sky?" Xiao Wuhua looked very much looking forward to it.

"Absolutely! Have you ever seen a Kong Ming lantern? As long as we make a cloth bag the size of a house, hang a basket underneath, put a brazier at the mouth of the bag and light a fire, it can take us flying! Xiao Yao gave a confident smile.

"I really don't understand why your head knows so many things, and I don't know if what you say is true or false, I'm afraid you're talking big to deceive us into being happy!" Xiao Wuhua likes to quarrel with Xiao Yao.

"I think it must be true, Shiro won't lie to us, and he's a genius, what he said will definitely come true!" Xu Miao stood on Xiao Yao's side.

"Hey, Shiro Shiro is so sweet! He is a member of our Xiao family! Xiao Wuhua was a little jealous, took Xiao Yao's hand and hugged it tightly.

"I also know that Shiro is your younger brother, but I'm also Shiro's confidant, don't you see that we chant poetry against each other every day, and we have a lot of fun chatting!" Xu Miao was not to be outdone, and took Xiao Yao's other hand and hugged it.

Xiao Yao enjoyed the fun of hugging left and right, and pretended to be serious and said: "Hey, hey, I said that you are also everyone's ladies, famous young lady, you are casually pulling and pulling with people on the street, twisting and hugging, and you are not afraid of other people's jokes!" ”

The two little beauties were stunned for a moment, and then looked around, oops! Why was he so fascinated by this little pervert that he forgot that the three of them were still on the street, so why couldn't he help but hug him?

The two of them quickly blushed and wanted to let go of their hands, but this time it was Xiao Yao's turn to be unwilling, so he grabbed the jade hands of the two with both hands, and said with a shameless smile: "It's really a little embarrassing on the street, or we won't go to find Zu Yuan, go home first, I'll let you hug enough!" ”

Being teased by Xiao Yao like this, the faces of the two of them turned even redder, and they vigorously broke away from the wolf's claws, Xiao Wuhua, who was flushed, was a little annoyed and angry, and reached out to twist Xiao Yao's ears, but thought that he was still on the street, so he could only stop it, but a pair of big eyes stared at Xiao Yao.

Xu Miao, who was also blushing, thought that she actually took the initiative to hold a man in broad daylight, her little heart was pounding, her face was full of shame, don't look over, she didn't dare to look at Xiao Yao again, she could only whisper: "Miaomiao still wants to go to Boss Zu to see what method Shiro used, so that he could copy such a beautiful book for those soldiers in such a short time!" ”

Before the fire dragon camp arrived at the iron workshop, Xiao Yao was ready to give lessons to these people, and when it came to classes, books should be used, and when it came to books, he thought of printing, so he thought of movable type printing!

Movable type printing is one of the four great inventions of China, and gunpowder has been used by Xiao Yao in advance, so it should be reasonable to advance movable type printing by 500 years now.

Now printing technology still belongs to engraving printing, that is, the content of the whole page is carved out on the wooden board and then printed, after printing, this board is useless, time-consuming, more expensive!

So Xiao Yao asked Zu Yuan to open a new department, General Bookstore, which is used to print and publish all kinds of books, using movable type printing!

According to Xiao Yao's method, Zu Yuan found a large number of carving craftsmen, first made a blank with the same specifications with cement, and then engraved the reverse word at one end, burned hard with fire, and became a single cement type.

Before printing, it is necessary to typeset, use a framed iron plate as the bottom support, apply a layer of agent made of pine resin, wax and paper ash mixture, and then pick out the required cement movable type one by one and row it into the frame.

Fill a frame to become a version, and then bake it with fire, wait for the agent to melt slightly, use a flat plate to flatten the literally, and after the medicine cools and solidifies, it becomes a version.

When printing, as long as the ink is brushed on the plate, covered with paper, and a certain amount of pressure is added.

After printing, the agent is baked with fire, and the movable type can be taken off the iron plate, which is very convenient.

Zu Yuan is full of praise for this movable type printing method, with this technology, greatly reduce the cost of printing, there is no problem with how many books to print, go out to publicize, so that those literati who chase fame and fortune can realize the dream of publishing a book without spending much money, which is a good way to make money!

"So that's the secret to how quickly you can copy out books for those soldiers!" Xu Miao saw the pile of characters of different sizes in front of her and exclaimed.

After speaking, he picked up the word mold and looked at it and exclaimed: "It is a genius idea to make a word mold with mud, it is easy to engrave when the mud is soft, and it can be as hard as wood after baking!" ”

"Only a talented person like Shiro can come up with such an ingenious way, first engrave the words individually, and then combine the typesetting when you use it, which is convenient and fast, because the cost of printing books has been greatly reduced, and now a large number of literati and ink writers come to General Bookstore to print books, haha, Miss Xu even your grandfather Lord Xu also entrusted us to help him print books!" Zu Yuan praised Xiao Yao fiercely in front of the two little beauties.

Xu Miao pursed his lips and said with a smile: "My grandfather has written a lot of articles, and there are countless protégés, I have long wanted to print books and send them out, but the cost of printing books before was high, and people could only copy them by hand, but the font could not be consistent, not as beautiful as printing, but now it is a great wish of my grandfather!" ”

Zu Yuan pinched his mustache and said with a smile: "With this kind of printing secret technique, it used to be a large part of the cost of hand-engraved templates, but now it has become paper, so I have now acquired several paper mills, hired a lot of craftsmen to improve technology, and made a lot of paper, and now even the cost of paper can be reduced a lot!" ”

Xiao Yao applauded Zu Yuan's incomparably shrewd business acumen and praised: "It's still Boss Zu's business acumen, and he actually thought of taking the papermaking part under his umbrella!" The cost of printing is reduced, the cost of paper is also reduced, and the cost of reading books will be greatly reduced, so that more people can read books! This is a big event for the benefit of the community! Even those arithmetic books written by your ancestors, Boss Zu can print them in large quantities and circulate them widely! Ha ha! ”

Zu Yuan laughed and said: "Shiro is too exalted to me, but those arithmetic books on my ancestors can indeed be printed and circulated more, which can be regarded as a little filial piety to my ancestors!" But to be honest, at that time, I just wanted to reduce costs and make more money, and I really didn't think that I could benefit the community. ”

"Anyway, being able to make a large amount of paper now is the credit of Boss Zu! At that time, you can also make different papers according to different uses! Ordinary paper can be used to make writing, painting, and printing books, and if it is softer, you can wipe your mouth and sweat and wipe your buttocks! If you make it thicker and tougher, you can prevent knives and arrows! Yes, it can also be made into paper armor! Xiao Yao suddenly clapped his hands and said.
