I am a primitive

Purple-red stems, green leaves, with some thin fluff growing on them, it feels a little prickly to the touch, this thing looks very similar to the radish leaves of later generations.

Up to now, Han Cheng has actually been able to confirm that this kind of thing is a radish, because not long ago he pulled one up, and took a bite of the rhizome the size of the belly of a little finger underneath.

It is the familiar taste of radish, but the taste is far inferior to the radish of the later generations. It has less juice, less meat, and is not very crispy. There are quite a lot of 'strings' inside, and it is a bit stuffy to eat.

Moreover, the leaves of these radishes look extremely vigorous, but the radishes below do not grow very large.

But the thickness of the fingers, already stilettos want to bloom.

If Han Cheng wants to obtain the kind of radish of later generations, he will undoubtedly need to cultivate it carefully year after year.

But it's a good thing anyway.

People's emotions are easily affected by external objects, like Han Cheng, who was dizzy from making paper, but now he was stimulated by Houttuynia cordata and radish, and he soon got better.

Then he started thinking about papermaking again...

Five days later, Han Cheng pulled out a bundle of bark from the retting pit.

The bark retting was not very good, but he insisted on getting it out. After all, he was not very clear about paper making, so he needed to find out.

To what extent the bark for papermaking needs to be retting is the best, these need to be tested again and again.

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

"Dong dong dong..."

There was a lot of thumping sounds in the Qingque tribe, and Han Cheng took a big tree stick and pounded vigorously at the stone mortar that had not been used for a long time after he got the water reel.

Instead of millet in the stone mortar, it is the retting bark that has been cut into sections.

Papermaking requires pulp. This is another message about papermaking that he got from his vague memory after thinking hard.

Since it is pulp, it is a big deal. If you think about the one or two unretting straw fibers that sometimes appear in the workbooks of later generations, you can roughly understand what needs to be done.

Grinding with a stone mill makes it easier to pulp things, but it is not suitable for grinding bark, because the bark tends to get stuck in it.

Or in the future, after the papermaking technology of the Qingque Tribe is more mature, it can be considered to improve the stone mill and create a stone mill specially used for grinding paper pulp.

Compared with grain, bark is not easy to pound.

After sweating all over, it took almost an hour for Han Cheng to pound it into something that could barely be called a pulp.

Because I was not familiar with it, things didn't go smoothly. After I finished it, I scratched my head and thought about it. I thought about the big pool in the simple illustration, and compared and associated it with the tofu grinding before. Han Cheng Finally, put the pounded bark into a large idle tank and soak it with water.

Then imitating the people in the illustrations, pretending to mess around for a while.

The crushed bark scattered into the water one after another, but there were a lot of things floating on the water.

This is old bark.

It is the hard outer layer of the bark.

When pounding the bark, Han Cheng pounded all the bark together. Compared with the inner bark, the outer one was much more difficult to pound.

So much so that there are still many lumps that have not been smashed.

Recalling the awkward scene when he wrote in the past where there were unmashed fibers, Han Cheng found a small piece of linen, tied it to a branch that nestled in a circle, and made a Simple net bag.

It is said to be a net bag, but in fact it looks not much different from a fly swatter that is not stretched too flat.

One is that Han Cheng's skills are limited, and the other is that the linen tribe is not very rich.

The piece Han Cheng was looking for was the scraps left over from making clothes. The materials used were too frugal, so it was naturally extremely difficult to make a pocket.

However, whether it is a net bag or a fly swatter, it is not a problem to fish out the scum floating on the surface of the water tank.

After fishing, when you look into the water tank again, it is much more pleasing to the eye.

The bark is made into pulp, and the next thing that needs to be done is how to make the pulp into paper.

Han Cheng, who is holding a fly swatter, is a bit difficult to stand here.

What exactly is that rectangular object in the hand of the ancient man in the picture?

How can pulp be turned into paper with that thing?

This is something Han Cheng has been thinking about for a while, but he has never thought about it.

The state in his head is not much different from the pulp vat now, it's all a ball of paste.

This is the case with many things. It is not difficult for those who meet, but not for those who are difficult.The so-called interlacing is like a mountain, that's it.

Turning pulp into paper, which seems insignificant in the eyes of an insider, is enough to make people lose their hair in the eyes of a layman like Han Cheng.

Got it!

Han Cheng, who had been melancholy for a long time, suddenly became happy, and looked at the 'fly swatter' placed beside the water tank with piercing eyes.

It's not how good-looking the 'fly swatter' has become, but that some pulp was stuck on it at some point.

After seeing it, Han Cheng wanted to put it back into the water tank, but when he touched it, he was pleasantly surprised to find that it felt like paper...

"Hahaha……"

In the Qingque tribe, there was a burst of wild laughter, and Han Dashenzi, who was carrying a fly swatter, was extremely happy.

After laughing, he threw the fly swatter in his hand to the ground, and quickly ran to the place where the linen was stored.

They called a carpenter and someone who was proficient in sewing in the tribe. After a while of cutting, cutting, knocking, a rectangular object with a length of 1.5 meters and a width of [-] centimeters appeared.

There are wooden frames on all sides, and a piece of linen is pulled in the middle. The style is a bit like the iron sieve used to sift sand when building houses in later generations.

This is what Han Cheng wanted to understand through the 'fly swatter'.

Holding the newly made equipment in both hands, Han Cheng went back to the side of the vat soaking in the pulp, put the suggested sieve-like thing aside and propped it up with something, and then began to use the 'fly swatter' to scoop up the pulp in the vat, slightly After the simmering water, put the paste on a simple sieve.

Piece after piece.

After being confused for a while, Han Cheng stopped what he was doing, and frowned slightly again.

Because the pulp picked up from the water tank with a 'fly swatter' is relatively flat, but when it is put on a simple sieve, it will easily become crumpled.

Moreover, the pieces of paper pulp the size of a fly swatter are not easy to connect together, and they will be easily disconnected.

After thinking for a while, Han Cheng suddenly had a flash of inspiration in his head.

He threw all the pulp covered on the simple sieve into the water tank, stirred it with a stick, and then filled it into the water tank with the simple sieve.
