The Qingque tribe has no shortage of things like tree bark.
Land reclamation has been going on in the tribe all the time, and many trees have been cut down.
Some of these trees that were more suitable were left as building materials, and those that could not be used were burned into carbon.
With the refining of copper, the tribe's demand for carbon suddenly increased.
The used carbon is used to fertilize fields.
The remaining fine branches and leaves were collected and used as firewood. It can be said that they were fully utilized.
But now, before these trees are used for various purposes, their clothes are stripped off, and the culprit is Han Cheng.
The people in the tribe have always been extremely active in doing things ordered by the Son of God. They don't ask why, they only ask how to do it. This is the characteristic of most of them.
"Wow!"
A bundle of bark was tied up with vines and thrown into the tribe's retting pit, causing a splash of water.
"Wow, wow..."
There was a continuous sound, and several more bundles of bark were thrown into the retting pit.
Han Cheng still knew the first step of making paper. Just like retting before, it required microorganisms in the water to remove some things from the bark, leaving only the fiber.
This step is also a major source of paper mill wastewater.
However, things like wastewater are not a big problem for the Qingque tribe, because with the continuous reclamation of land, the tribe's fertilizers can no longer keep up.
Under such circumstances, no amount of wastewater from retting tree bark would be too much for Han Cheng.
Retting bark is a time-consuming task, so after throwing the bark into the puddle, Han Cheng was free to do other things.
At this moment, what he was thinking about was what the rectangular thing that the person in the picture was carrying to dry was.
Judging from the picture, it should be a key tool for making paper.
After thinking for a while, Han Cheng couldn't think of a reason, so he left the tribe and wandered towards the west.
When you can't think clearly about something, you can change your mood and clear your mind.
For Han Cheng, the best way to wake up is to walk in the fields, pull some grass, and fertilize crops or vegetables. Such things can always calm him down.
This may be related to his racial talent for growing vegetables.
The millet was green and about to emerge. The beans in more than two acres were as high as a calf. Han Cheng looked through them and found no bean bugs under the bean leaves. They looked ugly, but they could be sold for one.
Extremely high priced bugs.
What attracts Han Cheng's attention most now is no longer the bean field and the millet field, but the patch of land next to the vegetable field that is full of miscellaneous things.
Because this land will give you some surprises from time to time.
Han Cheng knelt down and pinched the rhizome of a small plant 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 find that they are very different from sweet potato leaves.
Put it to your nose and smell it, and a fishy smell will come out.
Yes, this plant is Houttuynia cordata, and it is one of the surprises Han Cheng found in this messy vegetation.
Although Houttuynia Cordata does not smell like much, it is actually a rare ingredient.
When spring first comes, the Houttuynia cordata that have been dormant all winter will emerge from the ground, tender and red.
At this time, pinch some of the Houttuynia cordata buds, put them in boiling water for a while, and cool them down. They will be really delicious.
Houttuynia cordata is not only delicious, but also a very good medicinal material. Han Cheng didn't know the other functions, but he remembered one very clearly, and that was to treat coughs.
When I was a child, there was a piece of Houttuynia cordata next to the vegetable garden at home. When I coughed, I pinched 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 preferred that this thing be sweet potato.
After all, sweet potatoes are a very high-yield crop, and their land requirements are not very high.
It is also convenient to eat. You can dig it out of the soil, wash it and eat it raw. You can also boil or steam it in water, which is very convenient.
Unlike beans, millet, rice, wheat, etc., many complicated and tiring procedures are required from harvesting to eating.
Sweet potatoes can be stored longer after being cut and dried.
However, Han Cheng could only think about such a good thing in his mind. After all, sweet potatoes are not native crops. If you want to get this crop, you need to cross the ocean by boat and go into the tropical rain forest.
Recalling the appearance of his tribe's canoe, Han Cheng felt that it would be better for him to die.
It's not impossible to get sweet potatoes.
Han Cheng suddenly remembered one thing, that is, he had not been able to determine the specific location of his tribe until now. If his journey this time was not to the earth but to another world, it would not be impossible to obtain sweet potatoes.
After thinking about it for a while, the national treasure figure he had seen in the bamboo forest near Luhe appeared in Han Cheng's mind, breaking his random thoughts.
With a guy like this around, the possibility that the place he is currently in 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 he went too far. Here grew another surprise that he discovered.
The surprise is the carrot!
The purple-red stems and green leaves are covered with some fine hairs, which feel prickly to the touch. They look very similar to the radish leaves of later generations.
By now, Han Cheng was actually able to confirm that this thing was a radish, because he had pulled one up not long ago and took a bite of the root the size of the belly of his little finger.
It has the familiar taste of radish, but the texture is far inferior to that of later generations of radish. It has less juice, less meat, and is not very crispy. There is quite a lot of tendons in it, which makes it a bit cumbersome to eat.
Moreover, the leaves of these radishes now look extremely strong, but the radishes underneath do not grow very big.
It's just as thick as a finger, and it's already starting to bloom.
If Han Cheng wants to obtain the kind of radish for future generations, he will undoubtedly need to cultivate it carefully year after year.
But no matter what, this is a good thing.
People's emotions are easily affected by external objects. Just like Han Cheng, who was dizzy when he was making paper. But now that he was stimulated by Houttuynia Cordata and radish, he quickly 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 was not retting very well, but he still insisted on getting it out. After all, he didn't know much about papermaking and needed to figure it out.
The optimal degree of retting for papermaking bark needs to be tested again and again.
