The bark is not lacking in the Blue Sparrow tribe at all.

The matter of clearing the land has been going on in the tribe all the time, and there are many trees that have been cut down.

Some of these trees, some of which are more suitable, are left behind and used as building materials, and if there is no way to use them, they are burned to carbon.

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

Used carbon is used to fertilize the fields.

The remaining small branches and leaves are collected and burned as firewood, so it can be said that they are used very well.

But now, before these trees are used in various ways, their 'clothes' will be ripped off, and the initiator is Han Cheng.

The people in the tribe have always been extremely active in doing what the Son of God commanded, and it is characteristic of most of them to ask not why, but only how to do it.

"Whoa!"

A bundle of bark was tied up by vines and thrown into the tribe's hemp pit, causing a splash.

"Whoa, whoa, whoa......"

There was a constant sound, and several more bundles of bark were thrown into the hemp pit.

Han Cheng still knows the first step of papermaking, just like the previous soaking hemp, 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 wastewater in paper mills.

However, such a thing as wastewater is 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.

In such a situation, no matter how much waste water from the bark of the tree is too much.

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

At this time, he was thinking about what the rectangular thing that the person in the picture was carrying to dry.

From the point of view of the drawings, it should be a key tool for making paper.

After thinking about it for a while, Han Cheng didn't come up with a reason, so he left the tribe and staggered to the west.

When you can't think about some things clearly, 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 grass, and fertilize crops or vegetables, which can always calm his mood.

This may have something to do with the fact that he has the racial talent of growing vegetables.

The millet was verdant, and at this time it was about to spit ears, and the beans of more than two acres were also as tall as calves, Han Cheng looked through it, and did not find a bean worm that looked bad under the bean leaves, but could be sold for an extremely high price.

What attracts Han Cheng's attention the most now is no longer the bean field and the millet field, but the land next to the vegetable field that grows with miscellaneous things.

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

Han Cheng squatted down and pinched the rhizome of a plant that was not tall from the land.

At first glance, the leaves of this plant look a bit like sweet potato leaves, but if you look closely, you will notice that they are very different from sweet potato leaves.

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

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

Don't look at Houttuynia cordata doesn't smell good, but it's actually a rare ingredient.

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

At this time, the young shoots of Houttuynia cordata, pinch some, boil the water for a while, after the cooling, it is really a rare delicacy.

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

When I was a child, there was a piece of Houttuynia cordata on the edge of the vegetable garden at home, and when I coughed, I pinched it, washed it and put it in a pot, boiled two bowls of water, and drank it.

In fact, compared to Houttuynia cordata, Han Cheng prefers this thing to be a sweet potato.

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

It is also easy to eat, it can be dug out of the soil, washed and gnawed raw, and boiled or steamed in water, which is very convenient.

Unlike beans, millet, rice, and wheat, it takes a lot of complicated and tiring procedures to get from harvesting to eating.

After cutting and drying into dried sweet potatoes, they can be stored for a longer time.

However, such a good thing, Han Cheng could only think about it in his heart, after all, sweet potatoes are not a locally grown crop, and if you want to get this crop, you need to cross the ocean by boat and drill into the tropical rainforest.

Thinking back to the appearance of his tribe's canoe, Han Cheng felt that it was better for him to die.

It's not impossible to get sweet potatoes.

Han Cheng suddenly remembered one thing, that is, he couldn't be sure of the specific location of his tribe until now, if his crossing this time was not the earth but the other world, it was not impossible to get sweet potatoes.

After thinking like this for a while, the figure of a national treasure that he had seen in the bamboo forest near the Luhe River appeared in Han Cheng's mind, breaking his cranky thoughts.

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

Han Cheng looked away from Houttuynia cordata, stood up and walked to another place, and before he had gone too far, he stopped, where another kind of surprise he had found grew.

This surprise is the radish!

The purple-red stems and green leaves with some fine fluff on them are a little prickly to the touch, and this thing looks very similar to the radish leaves of later generations.

By now, Han Cheng was actually able to determine that this kind of thing was a radish, because not long ago, he had plucked one and took a bite of the rhizome the size of the little thumb and belly below.

It is the familiar taste of radish, but the taste is far from the radish of later generations, there is less juice, less meat, not too crispy, there are a lot of 'tendons' in it, and it is a little stuffy to eat.

And now these turnips, the leaves look extremely vigorous, but the radishes below do not grow much.

But the thickness of the finger is already up and wants to bloom.

Han Cheng wanted to get the kind of radish for the next generation, and he undoubtedly needed to be carefully cultivated year after year.

But either way, it's a good thing.

People's emotions are easily affected by foreign objects, just like Han Cheng, the whole person who was made by the paper thing was dizzy, and now he is stimulated by Houttuynia cordata and radish, and he quickly gets better.

Then he began to think about papermaking again......

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

The bark was not very well made, but he insisted on getting it out, after all, he didn't know much about the paper, and he needed to figure it out.

The best degree of preparation for paper-making bark needs to be tested again and again.
