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

The most powerful generals in the tribe, such as the eldest brother, did not participate much, because just going out hunting and obtaining enough food to fill the tribe's stomach had already consumed almost all of their energy.

All they could do was take advantage of some rare free time to transport rock salt from the salt mountain to the river.

This made Han Cheng quite helpless. The food problem was always a sword hanging over his head. If the food problem could be solved completely, the productivity within the tribe would be greatly liberated, and they would have more energy to do other things.

But how easy is this?

Han Cheng's motherland in his previous life was strong enough and had a long history. It was only in the last 20 to 30 years that the people were able to live without worrying about famine...

Fortunately, the salt consumption is not too great. As they become more familiar with the salt-making process, Han Cheng and his team can refine about ten kilograms of salt every day. These ten kilograms of salt are enough for the tribe to use for a month.

After the tribe's salt reserves reached five jars weighing more than 100 kilograms, Han Cheng was no longer as tight-lipped as before.

Instead, the daily amount of salt produced was reduced by nearly half.

During the salt-making process, they also fired two more kilns of pottery, mainly casting pottery basins, pottery jars and other things needed for salt-making.

As there were enough pottery in the tribe, Han Cheng advocated the decision to reform the pottery-making technology.

The focus of the reform was not the technique of making pottery, but the kiln in which the pottery was fired.

The advantage of using this simple clay kiln is that it is easy to build and easy to master. However, it also has a disadvantage, which is that it is too troublesome. Every time pottery is fired, it needs to be re-pasted with clay.

It is more convenient to use a kiln built with bricks.

Of course, building a kiln with bricks was very troublesome at the beginning, especially building the kiln, which Han Cheng only had a general idea about.

In addition to overcoming difficulties such as digging cellars, making bricks, and designing shapes, the control of the fire and other things also require little by little exploration and summary of experience.

But it doesn’t matter. Which technological development has not gone through such steps?

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

From then on, the Qingque tribe could only use simple clay kilns, and the pottery-making technology stopped there.

Don't stop eating because of choking.

They can't make bricks now, not only because they don't have kilns to burn bricks, but another important reason is that they don't have enough fuel.

Brick firing takes too long. If you rely solely on firewood to fire the bricks, it will take at least four or five days to make them hard and solid, even if there is a brick kiln.

If it is Shaoqing bricks, a large amount of water will need to be poured down from the top of the kiln, and it will take almost two days to fill the water.

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

It is really not worth it to make bricks at this stage.

Of course, pottery is different from brick-making because the kilns for firing pottery are smaller and the temperatures required are much lower than those for firing bricks, and pottery is thinner, so much less fuel is consumed.

The lack of bricks did not pose a problem for Han Cheng, as he could still build the kiln without bricks.

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

The brick blank is relatively easy to make, which is to mix the mud, then put the mixed mud into the mud mold and press it into a rectangle, and then dry it in the shade.

Bricks in later generations are generally five thick, ten wide, and twenty long. Such specifications obviously do not meet Han Cheng's requirements.

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

As for the earth pit needed to build the kiln, it could only be dug slowly using simple tools.

Fortunately, there was no rush to build a kiln and fire pottery. They had enough time to do it. After all, pottery was not a consumable, and they also had a simple mud kiln to support them.

However, he was not in a hurry about this matter, but Heiwa was very anxious. After all, he was now the best pottery maker in the Qingque tribe.

(Of course, Shenzi needs to be excluded, because Shenzi has many wonderful ideas, but his practical ability is not good)

Heiwa regained his confidence from this. Because he felt a sense of accomplishment in this, he became more and more fond of pottery making. When he heard Han Cheng say that there was a better way to make pottery, he couldn't sit still.

He was the most energetic when it came to digging pits and making adobe bricks.

According to the rules of the tribe, Heiwa is now an adult. If it were in the past, he would have to go hunting with his senior brothers every day.

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

Heiwa was a good pottery maker, so he was not allowed to go hunting with him. Instead, he concentrated on making pottery and boiling salt.

While doing all these, Han Cheng did not neglect the rapeseed. More than ten days ago, he led his people to suspend the production of salt and transported back the already mature rapeseed that had been cut in half.

During this process, Han Cheng specifically instructed that one should be careful and never touch the rapeseed pods too often.

Han Cheng did not wait until the rapeseeds were completely dry before collecting them, as he would have lost them if he had done so. Instead, he collected them while there was dew. Even if he touched the rapeseed pods, he would not spill much.

The harvested rapeseed was placed on a small piece of cleared land not far from the entrance of the tribe to dry.

This open space was opened up a few days ago at the instruction of Han Cheng.

In addition to removing the weeds and small trees on the ground, Han Cheng also had people take advantage of the wetness and use flat stones to hit the area of ​​about 11 or 12 square meters twice to make the soil firm and smash the small stone particles on the soil back into the soil.

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

Even though this area is only about 11 or 12 square meters, Han Cheng and his team put a lot of effort into getting them out.

Due to the lack of tools, it took a lot of effort just to clear the weeds, small trees and bushes.

This is because there are no big trees in this small area. If there were big trees, they would only be able to watch helplessly.

If you want to fell a big tree, you can't do anything with just stone axes or bone axes, even if everyone works together for a whole day and night.
