I am a primitive

After seeing everyone fix it, Han Chengcheng gave the order again.

That's right, what Han Cheng is leading people to do now is to make paper.

Papermaking has been pointed out as early as a few years ago, and the tribe has also been able to make paper.

However, the material used is made of such things as the inner thin fibers of the bark, and the color is somewhat yellowish.

This is not the most important thing. The most important thing is that it is too soft, and it can be written on it, but after all, it is still not as good as the paper specially used for writing in later generations.

Moreover, if the ink is too thick and the handwriting is too obvious, it cannot be written on both sides.

In this regard, Han Cheng has long wanted to make changes, but he doesn't know too much about papermaking. Before guiding Shito to make such paper, he has almost emptied all his knowledge about paper. knowledge.

But writing and transcribing textbooks for a period of time gave him the idea of ​​improving paper again.

While thinking hard, at some point, a flash of inspiration really made him think of some new things about papermaking.

This seems to be what he saw in an online novel before time travel.

When he watched it at the time, he didn't pay too much attention to it, but just looking at it like that, it passed away, and the impression left was not deep.

If it weren't for the fact that I was always thinking about improving papermaking during this period of time, this period of memory might not be able to come out.

Moreover, even in retrospect, it is very vague.

Using bamboo as a raw material for papermaking and retting is obtained from that seemingly vague memory.

As for why lime was added to it, Han Chengcheng didn't quite understand, and he didn't know whether it was to speed up the decay of bamboo or to bleach it.

Not only is the effect unclear, but the lime was added when the bamboo was soaked at the beginning, or was it added after a period of time, or after the bamboo was soaked for a while, and then added. It is not clear whether to add it to it.

But this does not prevent Han Cheng from directing people to do so.

Leave it alone!

Anyway, the general direction has already come out, and the rest will be tried a few more times, and the process and results of each experiment will be recorded and summarized, and it will be gradually explored.

At this time, the people in the tribe also came over with three heads of lime according to Han Cheng's request.

"Sprinkle two heads of lime evenly into this pit, and pour one head of lime evenly into this pit."

Han Cheng pointed to the two small pools closest to the shore, and explained to the person who came over with lime.

The two operated according to Han Cheng's instructions, and quickly held the handle of the stump head with one hand, and lifted the side of the stud head with the other hand, and poured it into the two small pools more evenly.

These limes have not been soaked in water, so after entering the water, heat is easily released, not only hot air, but also some bubbles.

Already before, I had already obtained the stone handed over by Han Cheng. Without Han Cheng reminding me, I took a pen consciously and recorded these things, and also recorded the time.

As for the remaining four small pools, Han Cheng didn't ask anyone to pour lime into them.

Instead, I want to wait until the soaked bamboos start to rot after a while, and then pour lime into two of the pools.

It's still like today, one pours more, and the other pours less.

As for the remaining two pools, wait until the bamboo is completely rotted before pouring lime into them.

After such an operation, and then comparing the final product, it is easier to tell when it is appropriate to add lime to it.

After finishing these, Han Cheng told Shitou and the others not to let the water in several pools mix together, let alone let the water flow into the small river.

It's not just about worrying that the mixing of water from several ponds will affect the effect of the experiment. More importantly, the water of retting is very strong and pollutes the water, especially the water with lime added.

This is an existence that can poison fish to death.

Han Cheng once experienced similar things. When a family in the village built a house, they bought several carts of lime and soaked it in water in the pit.

The lime pit is near a drainage ditch.

There is no obstacle on weekdays, but it will not work after a heavy rain in summer. The lime pit is directly connected to the drainage ditch, and then the water and some lime in it are washed into the stream.

Then the fish and shrimp in the stream suffered, and many were poisoned to death.

After going down into the water, Han Cheng and some children from Murakami often picked up fish along the stream...

For Han Cheng's explanation, people in the tribe such as Shitou naturally remembered it.

After doing these things well, Han Cheng and his party left here and there one after another, and started to work on their own.

After another period of growth, the first batch of millet planted in the tribe has humbly bowed its head, and it won't be too long before it can be harvested.

People in the tribe also need to prepare for this year's autumn harvest.

At the same time, it is also necessary to prepare for Han Cheng and the others to go south...

"Once upon a time, there was a little donkey who lived with its mother by the small river. One day, the mother called the little donkey to her side and said, "Little donkey, you have grown up and can graze by yourself. Today, you Go and graze on the meadow on the other side of the river... Donkey! Donkey! Don't go down! The river is deep..."

Inside the large tile-roofed house, the stone is holding a Chinese book wrapped in sackcloth in his hand, standing on the podium, and reading the story of "Little Donkey Crossing the River" to the children sitting there in the tribe .

After a period of production, the first batch of Chinese textbooks of the Qingque tribe has come out, with a total of 31 books.

One of them is used as a textbook for the teacher, and the other is distributed to the children of the Qingque Tribe who need to go to school.

The current minors of the Qingque Tribe, including slaves and citizens, are about 900 people. Even if those minors who are too young to go to school are excluded, among the green brick and tile houses at this time, It was still full of people, almost 500 people.

There are so many people, but there are only thirty books. Of course, this is not enough for everyone to share. It takes nearly 20 people to get one book.

But there is no way, now that time is limited and technology is limited, it is a little difficult to copy from book to book, so I can only make do with it first.

After a while, there will be more and more textbooks.

However, although there are very few textbooks, the novelty and excitement of the children in the tribe are not lacking at all.

In the past, they never thought that one day they and others would be able to use such things to study. They never thought that the things Shenzi and the others had taught themselves and others could be summed up at once and written down. Into what the Son of God called a 'book'.

Moreover, this book is still so exquisite, it is not only bound with leather rope, but also carefully wrapped with precious linen on the outermost layer.

Almost at the first sight of seeing these books and knowing what the books are for, the children in the tribe fell in love with these books.

The child who was sent to the book and was responsible for holding the book in his hands for the people around him to read ran outside first, soaped his hands, and scrubbed them carefully. He ran back holding the beautiful book in both hands, and opened it carefully.

It's like holding a fragile rare treasure.

The minors who seem to be careless on weekdays have become extra careful and patient at this time.

After opening this exquisite book, some minors with relatively good literacy were immediately deeply attracted by the content written in it.

It contains not only the familiar stories such as "little tadpole looking for mother" and "monkey fishing for the moon", but also many new stories that have never been heard before.
