And like hemp, it is pressed with large stones to prevent it from floating.

However, unlike when hemp is that the pond used to soak bamboo is not connected into one, and it is divided into several smaller ponds, and the water between them will not be connected.

And each small pond is soaked with a bunch of bamboo.

"Get three more limes."

Seeing that everyone had finished it, Han Cheng ordered the person again.

That's right, what Han Cheng is doing now is making paper.

Papermaking was already pointed out a few years ago, and the tribe was able to make paper.

However, the materials used are made of thin fibers inside the bark, and the color is a bit yellow.

This is not the most important thing. The most important thing is that it is too soft and can be written on it, but in the end, there is no easy use for paper specially used for later generations.

Moreover, if the ink is too thick and the handwriting is too obvious, you cannot write on both sides.

Han Cheng had long wanted to make changes in this, but he didn't know much about papermaking. He had guided Shi Tou to get such paper out, and almost emptied all his knowledge about paper.

But this period of time of writing and copying textbooks once again made him think about improving paper.

While thinking hard, he was thinking about something new about papermaking.

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

When he was watching it, he didn't care too much, but when he saw it that way, he passed by and the impression he 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 memory might not have been revealed.

Moreover, even when I think about it, it is very vague.

Using bamboo as raw materials for papermaking and fermenting is what you get from the seemingly vague memory.

As for why lime was added into it, Han Chengru didn't understand it very well, and he didn't know whether it was to accelerate the corruption of bamboo or to bleach.

Not only do I remember the function clearly, but I don’t even know how to add these limes when I first soaked the bamboo, or I will wait for a while before adding it, or after soaking the bamboo almost and adding it to it, I don’t know how to add it.

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

What if it doesn't matter!

Anyway, the general direction has come out. If you try the rest a few more times, record and summarize the process and results of each experiment, and you can slowly find out.

At this time, the people in the tribe also came with three limes as Han Cheng asked.

"Spread two limes evenly into this pit, and pour a lime evenly into this pit."

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

The two of them followed Han Cheng's instructions, and soon held the handle of the mattress in one hand, lifted the edge of the mattress with the other hand, poured it into the two small ponds evenly.

These limes were not soaked in water, so after entering the water, it was easy to release heat, not only hot air, but also some bubbles emerged.

I had already received the stone written by Han Cheng before. Without Han Cheng's reminder, I consciously took the pen and recorded these things, and also recorded the time.

As for the remaining four small ponds, Han Cheng did not let someone pour lime into it.

Instead, I wanted to wait until after a while, the soaked bamboos began to corrode and pour lime into two of the ponds.

It’s still like today, one falls more and the other falls less.

As for the remaining two ponds, after the bamboo has completely rotted, lime is poured into it.

After doing this, and comparing the final product, it is easier to tell when it is appropriate to add lime to it.

After doing this, Han Cheng told Shi Tou and others not to let the water in the pools be mixed together, nor to let the water in it flow into the river.

This is not just a worry that the water from several ponds will affect the effect of the experiment after mixing it together, but more importantly, the water from the fermented things is very strong and polluted greatly, especially the water with lime added.

This is an existence that can poison the fish.

Han Cheng once experienced similar things. A family in the village built a house and bought several trucks of lime and soaked them in water in the pit.

The pit where lime soaks is close to a drainage ditch.

There is no obstacle on weekdays, but it doesn't work after a heavy rain in summer. The pit of lime soaked is directly connected to the drainage ditches, and the water and some lime inside are washed into the stream.

Then the fish and shrimps in the stream were affected and many were poisoned to death.

After the water went down, Han Cheng and some of the children in the village picked up fish along the stream...

People in the tribe such as Shitou will naturally remember Han Cheng's explanation.

After doing these things, Han Cheng and his group left here one after another and began to work hard.

After this period of growth, the first batch of millet planted in the tribe has humbly lowered its head and cannot be harvested in too long.

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

At the same time, we also need to prepare for Han Cheng and his team to go south...

"Once upon a time, there was a little donkey living by the river with its mother. One day, the donkey mother called the little donkey to her side and said, "Little donkey, you have grown up, you can go to the grass on your own. Today, you go to the grass on the other side of the river to eat grass...Little donkey! Little donkey! Don't go down! The river is so deep..."

Inside the large blue brick house, Shi Tou held a Chinese book wrapped in linen in his hand, standing on the podium, reading the story of "The Little Donkey Crossing the River" to the children sitting in the tribe.

After a period of production, the first batch of Chinese textbooks from the Qingque Tribe have been released, with a total of 31 books.

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

The Qingque Tribe now has about 900 minors who have combined slaves and citizens. Even if they are young, they are not suitable for school, the large blue brick houses are still full of people, almost 500.

There are so many people, but only thirty books, which is certainly not enough for everyone to share. It is almost twenty people who can get a book.

But there is no way. Now the time is limited and the technology is limited. It is difficult to copy one by one, so I can only do it first.

After a while, the textbooks will gradually increase.

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

In the past, they never thought that one day they could use such things to learn. They never thought that the Son of God and others had taught themselves and others that could be summarized together at once and all of them were written into a book called "book" by the Son of God.

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

Almost the first time I saw these books and knew what the books were for, the children in the tribe fell in love with them.

The child who was sent to the book, who was responsible for holding the book with his hands and letting people around him read it, ran out first, put soap on his hands, rubbed his hands carefully, and then ran back to hold the beautiful book in both hands and carefully opened it.

It's like holding a fragile rare treasure.

Minors who seem frivolous on weekdays become extra careful and patient at this time.

After opening this exquisite book, some minors who read a lot of literacy were immediately attracted by the content written in it.

There are not only stories that they are familiar with, such as "The Tadpole Finds Mother" and "The Monkey Fights the Moon", but also many new and never heard of.

These wonderful stories made them reluctant to take their eyes away, and even more reluctant to close the books in their hands.

Han Cheng, who was also sitting in the big tiled house of Qingque, looked at the children holding textbooks and seemed to have found a treasure, and couldn't help but sniff.

I remember when I first received a book with ink flavor when I was in preschool. Although my reaction was not as good as those of the children in the tribe, I was also filled with joy and excitement. I couldn't bear to get it dirty. I really wanted to know what was written on it.

Of course, later, I tore off some book paper to use it to orchestrate the airplane and fold the four corners.

I just don’t know if these children in the tribe will be like they did when they were young.

Thinking about the good things he had done in his mind, the son of Han quickly decided to give up a discount to his leg if he dared to tear the book.

Who says that if the upper beam is not straight, you will want to have the lower beam crooked?

Moreover, as long as he doesn't tell the glorious history himself, no one in the tribe will know about it.

In the minds of the tribe, he will still maintain an extremely majestic image.

Although there were many people in the large blue brick house and full of crowds, they were surprisingly quiet. They could only stand on the podium, holding textbooks in both hands, and reading to everyone, and the sound of stones echoed.

The rest of the people listened attentively to Shi Tou's reading, and were attracted by the wonderful story of "The Little Donkey Crossing the River", and were immersed in this brand new and particularly attractive story.

Not only the children in the tribe, but also the adults in the tribe who were listening in the classroom, or at the door and windows of the classroom, listened very seriously.

Han Cheng looked at everyone's reaction and was satisfied.

This shows that I am still very successful in adapting this text.

After a while, Shi Tou finished reading the text. He moved the textbook to his left hand, took out a ingot of chalk from the chalk box made of the bamboo tube, turned around in the middle of the highest part of the blackboard behind him, and wrote the words "Little Donkey Crossing the River".

And write ‘one,’ below and start writing new words that have been summarized.

This blackboard was made of wood boards by Zi and the others. After flattening the surface with a plane, they brushed it with ink several times.

As for chalk, it is made by soaking lime in water and putting it into a round mold and drying it.

Although it is not as useful as the blackboard and chalk in later generations, it can still be used as a barely do, at least it is much easier to use than the sand table.

The words written in the sand table are not clear enough. The most important thing is that they cannot be established. Only a few people around can see them.

Unlike blackboards hanging on the wall, the words written on them can be seen by everyone in the house.

Moreover, the blackboard is large enough to write a lot of content at one time.

Not only are the big blackboards hanging on the walls, but now the children in the tribe basically have a small blackboard with double-sided sides, and can write clear words on it.

You can also raise the small blackboard in your hand according to the teacher's requirements, so that the teacher standing on the podium can see if the writing is correct.
