Lan An thought about it carefully and felt that Chu Qiu Ze really didn't seem to be of any use to him. For a moment, he felt deeply powerless and frustrated.

As a prince, he is completely useless in front of Chu Qiuze.

Chu Qiuze didn't think so much. The only person he asked for help from was Lan An, and he also asked for the gratitude from the person above him.

He did not deny that he fell in love at first sight at the stunning glimpse he had when they first met, and it was all about her face. However, after spending some time together, he clearly knew that his attraction was not just a temporary one.

People in their twenties can no longer confuse between liking someone and liking them.

Although this prince was a little more aggressive, had a strange temper, and a cold face, he could feel that Lan Euan's heart was passionate.

And he wants to be that raging fire, to make Lan An's heart completely hot.

"My idol." Lu Ziye, who was having fun, carefully held a box of tissue paper with both hands. "Is this paper? Why is it so soft? How can I write on it?"

The two people were in the middle of a heated discussion, each with their own thoughts, when their conversation was interrupted.

Lan An frowned, not approving of Lu Ziye's behavior as a guest at someone else's house. "That's not rice paper, you can't use it to write."

Lu Ziye was even more confused. What else could he do with the paper if he didn't use it to write?

"That's a napkin." Chu Qiuze satisfied the curious baby, "It's used to wipe your hands, mouth, and even buttocks. There's another kind of paper for writing."

As a military general, I was shocked to hear about wiping my butt with paper. What would happen if a scholar heard it?

"It's such a waste of nature's gifts!" Lu Ziye sighed as he took out a piece of paper and rubbed it against his face: "It's so soft and delicate, and feels more comfortable than silk."

Chu Qiuze raised his eyebrows. He had forgotten what people used to wipe their butts in ancient times.

Stones? Bamboo strips? Won't it cause anal pain?

Thinking of this, he asked, "Blue friend, what do you use to wipe your butt?"

Lan An was also shocked when he first learned that this tissue was used to wipe the butt, but he knew that Dahan's craftsmen were not capable of this skill, so he did not mention it again.

He opened his mouth, unsure of how to answer.

"Most common people probably use bamboo strips or leaves," Lu Ziye answered for Lan An. "Families with plenty of money use linen or cotton, and the nobles mostly use silk."

Chu Qiu Ze was speechless. This was such a waste of resources!

In ancient times, it was so troublesome to weave cloth. Wouldn't it be better to use it to make two pieces of clothing? Or to wipe your butt? ? ?

"However," Lu Ziye added, "most of them are recycled, and can still be used after being washed."

Chu Qiuze suddenly wanted to act out his death on the spot, and was so disgusted that he even wanted to vomit up the food he had eaten the previous night.

It's better to use bamboo strips and leaves than to recycle them! Wait? Bamboo strips don't have to be recycled, do they?

Gah! Chu Qiuze couldn't help but vomit.

He trembled in his little voice, "Friend Lan, how about we not talk about food for now, and discuss papermaking first? Can we research out toilet paper, or upgrade your rice paper?"

Lan'an's eyes lit up. If the papermaking technology could be improved, even if it couldn't be used to wipe one's butt, at least all the students of Dahan could afford it.

You have to know that for an ordinary family to support a scholar, the whole family would have to tighten their belts. The biggest expense was not the tuition, but the pens, ink, paper and inkstone. The most expensive and most used of them was Xuan paper.

Chu Qiuze knew what Lan An was thinking by looking at his expression, and immediately took out his tablet to search again.

Papermaking technology has developed to the 21st century today. I don’t know how many times it has been improved, and I don’t know how much more advanced it is than Dahan.

However, Dahan’s craftsmanship is not up to the task, so he can only do it step by step.

Chu Qiuze pointed at the screen and began to explain seriously, and also discussed and researched with Lan An.

"Do you have a pen and paper?" Lan An listened very carefully and wanted to write it down.

"No need to remember." Chu Qiuze briefly operated on the tablet and said, "I'll just print it out for you."

Soon, rustling sounds came from the study on the second floor.

The two ancient people turned their eyes to Chu Qiuze, their meaning was very simple, they didn't understand what the sound was, nor what it meant.

"Come with me." Chu Qiuze took the two of them to the elevator. "There is a printer in the study, so we don't have to bother writing by hand."

Lan Euan roughly understood printing, but didn't know how to operate it.

But Lu Ziye's mind was no longer on the printer, he was curious about the elevator.

It is really incredible. Once you stand in, you can reach the second floor in the blink of an eye.

"My god, is this also some kind of magic?"

"No." Chu Qiuze patiently explained: "This is an elevator, driven by a machine."

Lu Ziye exclaimed again and again, this fairyland is really too magical.

When I got to the study, I was surprised to see that there were two people there.

The room is filled with bookcases filled with books. Even the royal library might not have so many books.

Lan An thought that this was a visitor to someone else's home and should be more polite, so he glanced at it for a few seconds and then paid no more attention.

But his approach is different, after all, his approach is more wild.

I picked one up at random and flipped through it: "My god, what kind of spell is this twisted thing?"

Chu Qiuze looked up and saw that he had just randomly picked a book in English. "That's a foreign language."

Lu Ziye nodded and asked, "Do you gods also have different nationalities?"

“Of course.” Chu Qiuze knew that he had almost let the cat out of the bag, so he quickly added, “The God Realm is also very large. Just like the Buddhas and Bodhisattvas you are familiar with, they are all from the Western Regions. We are the native gods of the East.”

Without waiting for the two to respond, he quickly took out the printed materials and said, "Would you like to see the papermaking technique?"

Sure enough, the two people's attention was drawn away again.

Lu Ziye's focus was on papermaking, but Lan Euan's focus was off the mark.

He looked at the square machine in front of him, wondering how it could print such a long text so quickly.

The person who knows Lan Euan best is only Chu Qiuze.

"How do you print text now?"

"The most widely circulated books are first carved and then copied with ink." Lan An replied: "Ordinary books are copied by students."

Chu Qiuze understood. Isn't this still stuck at the stage of woodblock printing? Not to mention copying. Hand copying is time-consuming and troublesome, and it is easy to make mistakes and omissions. It not only hinders the development of culture, but also brings unnecessary losses to the dissemination of culture.

After thinking about it, I realized that since we have talked about papermaking today, it would not be an exaggeration to talk about printing as well.

"Have you ever considered carving all the words into small pieces of a certain size, then finding them when needed, arranging them neatly, and then printing them?"

This is the rise to movable type printing.

The blue gum suddenly became enlightened.

Previously, books that needed to be printed had to have the entire text engraved before printing, but if the text could be engraved in advance, it would undoubtedly be much more convenient.

Chu Qiuze did not delay. He just had a general idea. With the Internet in hand, the world is at his fingertips. He searched for the production process of movable type printing and printed it out.

"Well, take it and study it slowly!"

Lan An looked at him deeply. He really didn't know how much knowledge Chu Qiu Ze had in his head.

These days, anything Chu Qiuze casually takes out is enough to change the development of the entire Dahan.

Take the initial cement recipe for example. Before they left Yugou County, they received a letter from the imperial city.

Cement has been successfully developed and is currently being tested in areas surrounding the imperial city. The ground is indeed flat and smooth, and is very strong and durable.

At this moment, the printing technology that had been used for generations was also improved in just one or two sentences from him.

He was not good at speaking and didn't know how to thank Chu Qiuze again.

Words of gratitude become empty words if you say them too much.

As a military general, Lu Ziye did not quite understand how important movable type printing was.

The generals were definitely curious about the weapons. "My God, what are the weapons you have here like?"

That's a lot to say, and it can't be explained word by word.

He simply found a modern war movie and said, "If you're not sleepy, I'd like to invite you to watch a movie? A war movie?"

Lan Euan has watched the movie several times and is quite interested in watching movies.

It was already past midnight, but he thought that he would just be traveling on a speedboat tomorrow, so he wasn't tired.

Lu Ziye is very curious. For a curious baby, how can sleep be more important than watching a play? Besides, it is normal to stay awake for days on the march or in battle.

What does it mean to not sleep this night?

The three of them reached a consensus immediately.

Chu Qiuze took the two of them to the video room, where they watched a war movie about the evacuation of overseas Chinese, which had all kinds of modern weapons.

The two ancient people watched with great interest and exclaimed in amazement from time to time.

Those wooden guns, bullets, and ammunition were so terrifying that they could kill people without leaving any trace even from a thousand meters away.

"My male god, is that sniper Mu Cang for sale? I'll give you money, can you help me buy one?" Lu Ziye spoke again.

"Well... this... this kind of weapon is regulated by the country. You can't buy it, and you can't buy it. It's illegal."

Lu Ziye sighed in disappointment. He also knew that with Dahan's current level, it was impossible to make such sophisticated weapons. He expressed great regret.

Chu Qiuze thought about it, left the audio-visual room, and went to his collection room. Although there was no Makkura, there was still the model.

"Take it and play with it." Chu Qiuze held the model. "It's just for show. It has no lethality and can't be used."

At this moment, Lu Ziye was as excited as a kid who got a new toy. This, this, this is too cool. Even though he can't use it, it's fun at least. He can't let it go after holding it.

There is no man who does not love weapons.

Blue Gum was also curious.

"This is for you." Chu Qiuze held a simulated hand-held wooden karaoke, which felt similar to the real one: "I'll give it to you to play with."

Lan An took the wooden sword, which was less than the size of a palm, and fell into deep thought.

He is now almost certain that Chu Qiu Ze is not a god, but the comparison between these weapons and Da Han's is really the gap between gods and mortals.

He could hardly imagine what kind of world this was.

I looked out the window and thought...it would be nice to go out for a walk.

Chu Qiuze didn't know what he was thinking. The movie had ended. "Everyone should go to bed early. We have to travel tomorrow."

That night, the two ancient people can be said to have gained a lot.

It is conceivable that Dahan will also make rapid progress because of tonight's conversation.

Lu Ziye hugged his model and fell asleep on the big bed with satisfaction.

Only Lan An stood in front of the window with a gloomy expression, looking at the high-rise buildings with flashing neon lights in the distance, and was very impulsive to go out and take a look.
