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 brothers and others in the tribe did not participate much, because just going out hunting and getting enough food for the tribe has already spent almost all of their energy.

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

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

　　 Just, how easy is this thing?

　　Han Sung’s previous motherland is strong enough and its history is long enough to truly be able to ensure that the people are not hungry, but it is only in the past 20 or 30 years...

　　 But fortunately, the consumption of salt is not too large. As the salt-making process gets more mature, Han Cheng and the others can refine about ten catties of salt every day, which is almost enough for the tribe to use for a month.

　　After the salt reserves in the tribe were more than 100 catties in five jars, Han Cheng didn't hold on as fast as before.

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

　　 On the way to salt production, they also burned the pottery of two kilns again, mainly casting pots and pots, which are needed for salt production.

　　 When the pottery in the tribe was enough, under the advocacy of Han Cheng, it was decided to reform the pottery-making technique.

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

　　The advantage of using this simple mud kiln is that it is more convenient to build and easy to master. There are also disadvantages, but it is too cumbersome. Every time you burn pottery, you need to use mud again.

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

　　 Of course, kilns built with bricks were very troublesome at the beginning, especially when building kilns. For Han Cheng, he only knows a rough idea.

　　 In addition to overcoming the difficulties of digging cellars, making bricks, and designing shapes, the mastery of fire conditions and other things need to be explored bit by bit and sum up experience.

　　 But it doesn’t matter, which technological development has not gone through such steps?

　　 If this trouble is also scared, and that trouble is also scared, then the world will stop moving forward.

　　 Their Qingque tribe can only use simple clay kilns in the future, and their pottery making skills have stopped there.

　　 Don't give up eating because of choking.

　　 Bricks cannot be manufactured 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 only depends on wood to burn. If you want to burn bricks and sinter them, you need at least four or five days of work under the premise of a brick kiln.

　　 If it is a small brick, a large amount of water needs to be poured from the top of the kiln. It takes about two days to turn off the water.

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

　　 It is really not worth the gain to burn bricks at this stage.

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

　　Han Cheng couldn't help it without bricks. He could also build a kiln without bricks.

　　 It's not that he has any superpowers, but that he can use brick substitutes-brick embryos.

　　 Brick embryos are better to make, that is, mud, and then put the mud in the mud to form a rectangular parallelepiped, and then dry it in the shade.

　　 Later generations of bricks 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 embryo by two.

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

　　 Fortunately, they are not in a hurry to build a kiln and burn pottery. They have enough time to do it. After all, pottery is not a consumable, and they have simple clay kilns to hold them.

　　 But he is not worried about this, but Heiwa is very worried, after all, he is now the first ceramic maker of the Qingque tribe.

　　 (Of course, except for the needs of the son of God, because the son of God has a lot of whimsical ideas, but the practical ability is not good)

Heiwa’s self-confidence was picked up from here. Because of the sense of accomplishment made on it, she became more and more fond of pottery. After hearing Han Cheng's suggestion of a better way to make pottery, she couldn’t sit still. .

　　 Digging a pit and making adobes, he is the most motivated.

　　 According to the rules of the tribe, the Heiwa is now an adult. If he used to, he would have to follow the big brother and them to participate in hunting every day.

　　 But now it's different. Salt and pottery have appeared. UU reading www.uukanshu.com made the big brothers realize the importance of these things to the tribe.

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

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

　　 During this process, Han Cheng specially confessed that he should be careful not to touch the rapeseed pods.

　　 Han Cheng didn't wait until the rapeseeds were completely dry before harvesting them, so they wouldn't be able to collect them. Instead, they got them back when there was dew. Even if they touched the rapeseed pods, they wouldn't be able to throw out much.

　　 The collected rapeseed was dried in a small open space not far from the gate of the tribe.

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

In addition to removing the weeds and small trees on it, Han Cheng also asked people to take advantage of the wetness and use flat stones to smash the area of ​​about eleven or two square meters with flat stones. Every time, smash the soil to make it solid, and all the small rock particles on the soil are smashed into the soil.

　　 So when it's time to hit the rapeseed, there will be no floating soil and no more small stones than rapeseed.

　　 Don't look at this area of ​​only eleven or two square meters. In order to get them out, Han Cheng and the others didn't take much effort.

　　 Because of the lack of tools, just cleaning up the weeds, and some small trees, bushes, it took a lot of effort.

　　 That's because there are no big trees in this small area. If there are big trees, they can only stare.

　　 wanted to bring down a big tree, relying solely on the stone axe and bone axe, everyone went into battle, and it was hard to do it all day and night.
