Ye Moxun took her to the private school. The morning classes were over. In the afternoon, Song Tantan would go every other day to teach the students who loved cooking how to cook. She came yesterday afternoon, but she wouldn't come this afternoon.

But Ye Moxun has been coming quite frequently lately. Before, she was wondering why he always went to the private school and stopped following her around begging for food.

"Look, it's finished. It won't be long before all the printing fonts we need are carved. Shui Sheng is very auspicious and capable." Ye Moxun pulled Song Tantan down to squat down and admired the dozen or so printing fonts that Shui Sheng and the others had carved.

"This is wooden movable type. We can have them try making clay movable type later. They'll definitely be able to do it." Ye Moxun was quite confident in others.

This is something to be happy about. It's true that you should let people who are interested and talented do things. Only when you like doing something will you devote yourself to studying it.

Well, it's time to find someone to try making paper. And cement must be produced quickly, so that all the effort she put into moving the limestone mine out of space won't be in vain. The resources aren't too many, but they must be used properly.

My aunt has been longing for a biogas digester, which will become increasingly necessary as the number of pigs she raises grows.

With cement, you can lay cement on the floor of your house, so you won't get wet when it rains, and your shoes won't always be covered in mud.

With cement laid in the yard, it will be much easier to dry rice next year. There will be no need to find someone to rush to weave rice mats, which would be wasteful of bamboo and labor, and wouldn't allow you to dry much rice. A cement paving is much more practical.

You wouldn't even think about it if you didn't have the resources, but right now it's possible to achieve it. We have limestone, all that's left is to make cement.

Ye Moxun rubbed his forehead. How did we end up back here again? How come our lives revolve around the Four Great Inventions? He seriously suspected that when he went back to mining limestone, he would end up inventing gunpowder.

Speaking of which, a compass is easier to make, but unfortunately it's not practical right now. Even if it were, he wouldn't need to invent it, because Song Tantan's supermarket has them ready-made.

"You have the nerve to frown? Although you copied the book and explained the production steps, you didn't participate much from beginning to end. It was all thanks to other people's hard work day and night. Shui Sheng and Ji Xiang didn't complain, but you're so fussy."

It's just asking him to teach people how to make paper and cement. He doesn't have to do it himself. He just needs to give some pointers. The paper and cement will benefit the whole village. Why make him feel so miserable?

"No, you have to come with me. I can't invent things all by myself. I'm ten years old, and I'm so tired."

"Wake up, you're actually twenty-eight years old. You should have been contributing to society long ago. Your physical condition isn't good right now, so you can only do mental work. At this time, you should show your extraordinary talent so that everyone can ignore the fact that you're not in good health and only see your amazing talent," Song Tantan teased with a chuckle.

"We're just showing off the experience accumulated by our predecessors here. How dare we take credit? I just think these people are quite stupid. They need to hear a knowledge point repeated at least three times to understand it. Some even need to hear it five, six, or more than ten times. It's hard to teach them."

"If everyone had a photographic memory, what would be left for you? Be content, genius." Song Tantan pulled him along to find people to prepare for papermaking.

“Making paper would not only solve the problem of printing books, but it would also make going to the toilet much more convenient. Every time you ask me for tissues, I can’t even imagine how you end up pressing all that paper into the latrine with a stick after you wipe your butt. Ugh.” Song Tantan gave an exaggerated dry heave.

Ye Moxun's face turned as black as the bottom of a pot. He stared at Song Tantan for a long time without saying a word. Although he didn't want to admit it, he did use a stick to push the tissue into the cesspool after wiping his butt with it.

"You're still laughing? Who am I doing all this for, enduring this disgust? Isn't it because I'm afraid your private space will be exposed?" Is it easy for him? Even now, he subconsciously lowers his voice when he says these things, afraid that someone will hear him.

“Who asked you to work so hard? You could use a stick or bamboo strips to scrape it. Everyone does it that way, and I heard it gets it pretty clean. But you're so fussy. You insist on making me give you roll after roll of tissue paper. I've lost count of how many rolls I've given you over the past year.”

"Why are you suddenly being so calculating again? We agreed that I'd share half of the profits with you. You can't keep bringing up my shortcomings now. Fine, I'll make paper, I'll definitely make it for you." There's just no way to deal with her.

So, the second day, Ye Moxun gathered a few men and teenagers from the village to make paper. To be honest, the villagers weren't very interested in papermaking, mainly because it wasn't very useful. They were trapped in the deep mountains, unable to go anywhere, and didn't want to go out.

The world is too chaotic. They just want to survive. The imperial court may not even exist anymore. They don't even dare to think about taking the imperial examinations. They don't think they are cut out for it.

If it weren't for the Song family giving them sweet potatoes and corn as payment for their labor, they wouldn't have come to make paper at all. Although they were relatively free after the autumn harvest, they still had to go into the mountains to hunt and chop firewood.

Many people built their houses in a hurry, and there weren't enough rooms to live in, so they thought about adding a few more rooms. Before building a house, they had to fire bricks and cut wood first.

The foundation hasn't been dug yet.

"Miss Song, your family has given so much grain to everyone. Will it be enough for you and Tantan to eat?" a man asked curiously, since the Song family often hired people to do chores.

Building pigsties, digging traps, and so on—people were hired to do the work in exchange for grain. Other families would settle accounts with each other, but since everyone was short of grain, no one was willing to give it up as payment.

Although the Song family didn't have any strong laborers, Song Zhuiyan was a very hard worker, no less capable than a strong man. However, apart from doing her own farm work, she never exchanged labor with others, but was willing to pay with grain, as if the family had too much grain.

“Of course we’ll only take it out when we have enough to eat. We’re not going to go hungry. Look at everyone in the village, which child is as plump as our Tantan? What does that mean? It means that we not only have enough food, but we’re eating very well,” Song Zhuiyan replied without any emotion.

Everyone was taken aback. Song Tantan was indeed the fattest person in the whole village. Not only was she chubby, but she was also very fair-skinned. No one was as good-looking as her. She looked like a child raised by a rich family.

Therefore, people privately speculated that Song Zhuiyan was the first person to discover the food in the cave both times, and that her family might have hidden a lot of food and clothing.

Although Song Zhuiyan and Song Tantan were dressed in dark colors, always in long sleeves and trousers like men, their clothes were quite strange, a style that no one had ever seen before.

People had long suspected that they had taken the opportunity to hide some nice clothes. The strange styles weren't the problem; the problem was that the fabric looked very soft and comfortable.

Song Tantan: Of course it's comfortable. These are all achievements from a thousand years later. The comfort of the fabric is naturally no less than that of modern silk.

That's right, her aunt always dressed as a man. Uh oh, no, they didn't intentionally dress as men. She and her aunt just didn't know how to style ancient hairstyles, and they didn't think they fit their aesthetic, so they were too lazy to learn how to style their hair and just tied it up in a high ponytail.

It just so happened that the men of the Jin Dynasty had hairstyles similar to high ponytails, tied high on their heads, so they became part of the group of women dressed as men.
