I am a Primitive Man

The production of salt is basically done by Han Cheng with the children of the tribe and the sick and disabled women and children.

The most powerful elder brother and others in the tribe did not participate much, because they had spent almost all of their energy just to go hunting and obtain enough food for the tribe.

All they can do is take some rare free time to transport rock salt from the salt mountain to the small river.

This made Han Cheng quite helpless. The problem of food will always be a knife hanging over his head. If the problem of food can be solved, the productivity in the tribe will be greatly liberated, and there will be more Energy to do other things.

But, how easy is this matter?

The motherland of Han Cheng's previous life was strong enough, and the history was long enough, so that the people could truly avoid the fear of famine, but it was only in the past twenty or thirty years...

Fortunately, the consumption of salt is not too much. With the familiarization of the salt-making process, Han Cheng and the others can refine about ten catties of salt every day. This ten catties of salt is almost enough for the tribe to use for a month.

After five jars of salt storage in the tribe exceeded one hundred catties, Han Cheng didn't hurry up like before.

Instead, it reduced the amount of salt produced by nearly half every day.

On the way to make salt, they also fired pottery from two kilns again, mainly casting pots and pots, which are needed for salt making.

When the pottery in the tribe was sufficient, under Han Cheng's advocacy, it was decided to reform the pottery making technology.

The focus of the reform is not the method of making pottery, but the kiln for firing pottery.

The advantage of using this simple mud kiln is that it is more convenient to build and easy to master, but it also has its disadvantages, that is, it is too troublesome, and it needs to be re-pasted with mud every time pottery is fired.

It is not as convenient to use a kiln built with bricks.

Of course, kilns built with bricks were very troublesome at the beginning, especially when building kilns, Han Cheng only knew a rough idea about this.

In addition to overcoming difficulties such as digging cellars, making bricks, and designing shapes, it is necessary to explore bit by bit and sum up experience for the mastery of the fire and others.

But it doesn't matter, which technology has not undergone such steps in its development?

If we are also afraid of this trouble and that trouble, then the world will stop moving forward.

The Qingque tribe can only use simple mud kilns in the future, and the technology of pottery has come to an end here.

Don't give up eating because of choking.

They can't make bricks now, not only because there is no kiln for burning bricks, but also because they don't have enough fuel.

It takes too long to burn bricks. It takes at least four or five days to burn bricks with only firewood.

If it is young green bricks, a large amount of water needs to be poured from the kiln roof, and it will take almost two days to turn off the irrigation.

Four or five days of uninterrupted burning, not to mention manpower and material resources, just the firewood burned, is a huge burden for the Qingque tribe with low productivity.

Burning bricks at this stage is really not worth the candle.

Of course, pottery is different from firing bricks, because the kilns for firing pottery are relatively small, and the temperature required is far lower than that of firing bricks, and pottery is thinner, so much less fuel is consumed.

Han Cheng can't help it without bricks, and he can build the kiln without bricks.

It's not that he has any superpowers, but that he can use a substitute for bricks - brick embryos.

Brick embryos are easier to make, that is, mix mud, and then put the reconciled mud into the mud fan to form a cuboid, and let the water dry in the shade.

The bricks of later generations are generally five in thickness, ten in width and twenty in length. Such specifications obviously do not meet Han Cheng's requirements now.

So he multiplied the length, width and height of the brick embryo by two.

As for the pits needed to build kilns, they can only be dug slowly with simple tools.

Fortunately, there is no rush to build a kiln and burn pottery. They have enough time to do it. After all, pottery is not a one-time consumable, and they have a simple mud kiln to support it.

But he is not in a hurry about this matter, but Hei Wa is, after all, he is the number one pottery maker in the Qingque Tribe.

(Of course, except for the needs of Shenzi, because Shenzi has many wonderful ideas, but his hands-on ability is not good)

Heiwa's self-confidence is picked up from this, because he has made a sense of accomplishment on it, so he loves pottery making even more. After hearing Han Cheng say that there is a better way to make pottery, he can't sit still .

Digging pits and making adobes, he is the most energetic.

According to the rules of the tribe, Heiwa is now an adult. If it was before, he would have to participate in hunting with the big brother and the others every day.

But now it is different. The appearance of salt and pottery made the brothers realize the importance of these things to the tribe.

And Heiwa is a good pottery maker, so he didn't let him go hunting, but concentrated on making pottery and cooking salt.

In the process of making these, Han Cheng did not miss anything in the rapeseed. As early as more than ten days ago, he led the people to suspend the production of salt, and transported the ripe rapeseed from half-cut pieces.

During this process, Han Cheng specifically explained that he should be careful not to touch the rapeseed pods too often.

Han Cheng didn't wait until the rapeseeds were completely dry before collecting them, otherwise they wouldn't be able to be collected. Instead, he took advantage of the dew to get them back, so even if he touched the rapeseed pods, he wouldn't be able to spill much.

The recovered rapeseed is placed to dry in a small open space not far from the gate of the tribe.

This open space was opened up under Han Cheng's instruction a few days ago.

In addition to removing the weeds and small trees above, Han Cheng also let people take advantage of the wetness to smash the area of ​​about eleven or two square meters with flat stones two times next to each other. Over and over, the soil was smashed hard, and the small stone particles on the soil were smashed into the soil.

In this way, when it is time to hit rapeseed, there will be no floating soil, and there will be no situation where there are more small stones than rapeseed.

Regardless of the fact that this area is only eleven or twelve square meters, Han Cheng and the others worked hard to get them out.

Because of the lack of tools, it took a lot of effort just to clean up the weeds, small trees and bushes on it.

This is because there are no big trees in this small area. If there are big trees, they can only stare blankly.

If you want to bring down a big tree, you can only rely on stone axes and bone axes, and all the people go to battle and chisel around for a day and a night.
