After Liu Tiankuo and Jiang Zhixia talked about the proposal, Jiang Zhixia let it go.

Since she doesn't understand the things in officialdom, she won't ask more.

On the second day, she continued to look at Han Wenxuan's account book that she had put down yesterday because of Liu Tiankuo's return.

Today, the shop's business is barely profitable. After all, the copied books can't keep up with the ones sold in the shop.

In her mind, she couldn't help but think of movable type printing again.

Actually, she had thought about it before, but because of this printing thing, it is easy to say, but it still requires space and manpower to operate.

At that time, she had no one and no power, so she naturally let it go.

However, yesterday Liu Tiankuo talked about offering advice to the emperor in order to obtain protection, and her heart moved again.

Nowadays, money is not entirely important to them.

Therefore, these useful methods can completely exchange power for them.

However, about movable type printing, it is still the knowledge that Jiang Zhixia learned when he was in school many years ago.

She probably remembered that it was invented by Bi Sheng of the Northern Song Dynasty. Something is carved into reverse letters, then ink and the paper is placed on top to print.

However, it is easier said than done.

Therefore, she still has to think carefully about how the movable type printing technique works.

Even if it can't be detailed, at least there is a general idea, and after Liu Tiankuo listens to it, he can hand it over to the emperor and let the Ministry of Industry develop it.

In this way, Jiang Zhixia fell into the point of forgetting to sleep and eat all day.

After Liu Tiankuo came back, he saw Jiang Zhixia who was writing and drawing on paper.

"What are you doing here?" Liu Tiankuo looked at Jiang Zhixia, who was writing reverse words on the paper, and asked strangely.

"Ah, you're back? Is it so late? Jiang Zhixia heard Liu Tiankuo's voice and asked in confusion.

"Ruolan told me today, you sent everyone down, and left you alone in the room. You didn't even drink the medicine prescribed by Dr. Yang? ”

Liu Tiankuo saw the medicine on the desk in a blink of an eye, and said helplessly.

Jiang Zhixia smiled embarrassedly.

It was too hot when the medicine came, so she thought about waiting for it to cool down before drinking it.

Unexpectedly, she was immersed in her thoughts later, but she forgot to drink it.

"I'll drink it." After Jiang Zhixia finished speaking, he hurriedly stretched out his hand to take the medicine and continue to drink it.

"This medicine is cold. Let Dr. Yang boil it again. Liu Tiankuo said helplessly.

Dr. Yang is not only grateful for Jiang Zhixia's kindness at the beginning, but also because of the queen's will, so he is very concerned about regulating Jiang Zhixia's body.

Not to mention anything else, now that it's the end of March, Jiang Zhixia's clothes are not much different from ordinary people.

Unlike in previous years, I always wore several thick clothes.

Liu Tiankuo called someone in, took the medicine out, and asked Dr. Yang to boil it again.

Then, he hugged Jiang Zhixia and said angrily: "Say, what is it that makes you so concerned." ”

Jiang Zhixia then talked about the idea of movable type printing.

"You also read the book to see this idea?" Liu Tiankuo paused and asked in surprise.

"Uh... Be.... ”

Jiang Zhixia hesitated for a moment, originally she wanted to say no.

After all, everything is something that comes from reading books.

However, she didn't want to take credit from others.

About peppers, about cotton, about winemaking, it is impossible to find the original founder exactly.

However, movable type printing is not, it has an inventor, it was invented by Bi Sheng of the Northern Song Dynasty, although he invented clay movable type.

Although there is no dynasty in the Northern Song Dynasty now, and there may be no Bi Sheng as a person, it is not possible to turn this thing into her own invention.

"This is movable type printing invented by a man named Bi Sheng. He's a very powerful person. In the future, every book we printed should be written about this person. He deserves to be remembered for eternity. ”

Jiang Zhixia said solemnly.

Liu Tiankuo saw that Jiang Zhixia was so solemn and said the names of the people so clearly, so he naturally believed it.

"Hmm. I sure will. Don't bother with it. There are so many people in the Ministry of Works. You can't just wait for a meal. You tell me the general idea, and after I report it to the emperor, let them develop it. This is really a great thing for future generations. ”

Liu Tiankuo said with a sigh.

Nowadays, paper is expensive, but books are even more expensive.

If books are cheaper, then there will be many more people reading books.

When the time comes, enlightening and educating the people can be regarded as a great thing for the benefit of the country and the people.

However, Liu Tiankuo hesitated again.

Jiang Zhixia saw his hesitation, and hurriedly asked what was wrong.

"I just offered the cotton flowers, and if I were to hurry up and offer this printing technique, I am afraid it will be too eye-catching. Well, in another month or so. Don't worry, after thinking of these ideas, it's time to take a break. Liu Tiankuo said hesitantly.

After he offered the cotton flowers, the emperor announced the matter directly in the court.

He naturally put this credit on his own lady.

However, the emperor always called him over to inquire if he had anything to do after the dynasty was dispersed.

The people in the palace are all staring at it.

At present, the emperor always asked him if he was not satisfied, and today he asked him if he could cede a piece of cotton flower field and let the officials of the household department stay there to observe. Naturally, it was inconvenient for him to refuse.

When he came back today, he was about to tell Zhixia about it.

As a result, Zhixia gave him another big surprise.

"What you say makes sense, then you should report to the emperor later. After all, you'll have to report the ice making method again in the summer. If they are all together, it is indeed too eye-catching. ”

Jiang Zhixia said approvingly.

Then, Jiang Zhixia explained the idea of movable type printing to Liu Tiankuo in detail, and Liu Tiankuo personally wrote it on paper to record.

First of all, the word should be carved into an uneven anti-word mold, it is best to use copper, if not, you can also use cement.

Then, make a framed iron plate and coat it with a potion made of pine resin, wax and paper ash.

After that, pick out the words needed in the article one by one and put them in the iron plate. Roast the potion over fire, and then find a board to flatten and shape the characters.

Finally, the mold is brushed with ink. Spread another piece of white paper on top and press it with the whole board.

Wait until it is used up, then bake the potion with fire, and then shake it, and the mold will fall off.

When the time comes, those books will have molds of whatever font there are. Commonly used words can be carved with more molds.

As for how to carve, it is something that needs to be studied by the Ministry of Industry.

Liu Tiankuo looked at the words sorted out and said with a sigh: "This Bi Sheng is really amazing." ”

Jiang Zhixia echoed: "Yes, it's amazing. ”

She secretly apologized in her heart: "Bi Sheng, although I used your printing technique, I will still give you back this credit." Thousands of years later, people will still know that movable type printing was invented by you. Your credit will never be erased! ’
