I am a primitive

And at this time, linen was still a very rare item in the tribe. After use, it needed to be washed in the lower reaches of the small river and reused.

Even if children are the best way to cure cleanliness, and Han Cheng is not a cleanliness person, after being tossed back and forth like this, he finally couldn't stand it anymore.

Regarding papermaking, his earliest memory is the narration of "Caihou Paper" in history textbooks.

From there, he understood the materials used for paper, which are bark, hemp bark, and broken fishing nets, from which fibers are obtained.

There is also a pair of quaint illustrations, which are some situations of ancient craftsmen making paper drawn by ancient people.

I vaguely remember that someone was standing next to a large pool with a stick and was stirring, and someone was holding some long things to the side to dry.

Later, when I was looking at other things, I saw some records about paper manufacturing one after another, but because I didn’t pay much attention to it at the time, I just glanced at it and passed it directly, so Han Cheng is now too concerned about paper making. Extremely vague.

It was precisely because of this that Han Chengcai never tried.

But now I have to bite the bullet and try.

(Writing this out of feelings, raising children really shouldn't be too 'delicate' and 'exquisite', that's not loving children, but harming them again)

-------------Chapter Dividing Line---------------

The Qingque tribe does not lack such things as bark.

Land reclamation has been going on in the tribe, and many trees have been cut down.

Of these trees, some suitable ones were left as building materials, and those that could not be used were burned into carbon.

With the refining of copper, the demand for carbon in the tribe suddenly increased.

The used carbon is used to fertilize the fields.

The remaining fine branches and leaves are collected and used as firewood, which can be said to be fully utilized.

But now these trees, before being used in various ways, will be stripped off by people, and the instigator is Han Cheng.

People in the tribe have always been extremely active in doing what the Son of God ordered. They don't ask why, but how to do it, which is the characteristic of most of them.

"Whoa!"

A bundle of bark was bound by tree vines and thrown into the retting pit in the tribe, causing a splash of water.

"Whoa, whoa, whoa..."

There was a continuous sound, and several bundles of bark were thrown into the retting pit.

Han Cheng still knows the first step in papermaking. Just like retting before, it needs to get rid of some things on the bark through the microorganisms in the water, leaving only the fibers.

This step is also a major source of paper mill wastewater.

However, things like waste water are not a big problem for the Qingque tribe, because with the continuous reclamation of the land, the fertilizer in the tribe can no longer keep up.

Under such circumstances, no matter how much waste water from retting hemp and bark is, Han Cheng can't think too much.

Retting the bark is a time-consuming task, so after throwing the bark into the puddle, Han Cheng is free to do other things.

At this moment, what he was thinking about was what the person in the picture was carrying to dry in a rectangular shape.

From the pictures, it should be a key tool for making paper.

After thinking for a while, Han Cheng, who didn't think of a reason, left the tribe and wandered towards the west.

When you can't think clearly about some things, you can change your mood and clear your mind.

For Han Cheng, the best way to wake up is to go to the field, pull some weeds, and fertilize the crops or vegetables. Such things can always calm him down.

This may be related to his racial talent of growing vegetables.

The millet is verdant, and it is about to pop ears at this time, and the beans with more than two acres are as high as a calf. Han Cheng looked through it, and found no ugly bean worms under the bean leaves, but he could sell one. Extremely high price for bugs.

Now what attracts Han Cheng's attention the most is no longer the bean field and the millet field, but the miscellaneous land next to the vegetable field.

Because this piece of land will give you some surprises from time to time.

Han Cheng squatted down and pinched the roots of a low-rise plant from the land.

The leaves of this plant look a bit like sweet potato leaves at a glance, but they are very different from sweet potato leaves when you look closely.

Put it on your nose and smell it, and a fishy smell will hit your nostrils.

That's right, this plant is Houttuynia cordata, and it is one of the surprises that Han Cheng found in this messy vegetation.

Although Houttuynia cordata smells bad, it is actually a rare ingredient.

When spring first comes, Houttuynia cordata, which has been dormant for the winter, will emerge from the ground, tender and red.

At this time, pinch some Houttuynia cordata shoots, put them in boiling water for a while, and after cooling them, they are really rare and delicious.

Houttuynia cordata is not only delicious, but also a good medicinal material. Han Cheng doesn't know the rest of its effects, but he remembers one very clearly, which is to cure cough.

When later generations were young, there was a piece of Houttuynia cordata by the side of the vegetable garden at home. When you coughed, you took a handful, washed it, put it in a pot, boiled two bowls of water, and drank it.

In fact, compared to Houttuynia cordata, Han Cheng hoped that this thing was sweet potato.

After all, sweet potatoes are a very productive crop, and the requirements for the land are not very high.

It is also convenient to eat, dig it out from the soil, wash it and eat it raw, boil it in water or steam it, it is very convenient.

Unlike beans, millet, rice, and wheat, there are many complicated and tiring procedures from harvesting to eating.

After the sweet potatoes are cut and dried, they can be stored for a longer period of time.

But such a good thing, Han Cheng can only think about it in his heart. After all, the crop of sweet potato is not grown locally. If he wants to get this kind of crop, he needs to cross the ocean by boat and drill into the tropical rainforest.

Recalling the appearance of his tribe's canoe, Han Cheng felt that it would be better for him to die.

Getting sweet potatoes isn't out of the question either.

Han Cheng suddenly remembered one thing, that is, he has not been able to determine the specific location of his tribe until now. If he traveled this time not to the earth but to another world, it is not impossible to get sweet potatoes.

After thinking about it for a while, the figure of the national treasure that he had seen in the bamboo forest near the Lu River appeared in Han Cheng's mind, breaking his wild thoughts.

With this kind of guy, the possibility that the place where he is now is a different continent is not too great.

Han Cheng looked away from the Houttuynia cordata, stood up and walked to another place. He stopped before walking too far, and there was another kind of surprise he discovered growing here.

This surprise is the radish!
