With the departure of the two tribes, the life of the Celestial Dragon tribe gradually returned to normal productive life, and the task of cultivating the land became less urgent due to the acquisition of cattle.

The top priority was to obtain enough forage to prepare the livestock for the winter, and for such a result that the tribe was able to achieve before the snow this year, the entire Tianlong tribe, including Wang Tian, was not prepared.

So most of the people are working hard to get forage, even the 2o River tribe children who have just joined the Tianlong tribe are also among the working people.

Slender Toutuo was responsible for leading everyone to collect forage, while the second brother of King Kong had just led Liu Bei and others to start weaving fence walls, or it was more appropriate to weave squares made of rattan.

Wang Tian watched with some distress as the waterproof fence walls were erected to enclose the entire pavilion, which was made very thin, for the purpose of preventing rain, and behind such a wall, impermeable bricks would be placed, so that these livestock could also spend the winter in the pavilion.

In order to allow these brick embryos to bear greater weight and not be crushed by their own weight because they were not fired, Wang Tian asked the second brother to put the woven rattan squares in the red brick mold, and insert some branches and bamboo pieces in the middle part of the mold, which are used as steel bars to strengthen the toughness of these adobe bricks and make them stack higher.

You must know that the highest position of the pavilion is 3.5 meters, such a height, if it is not fired, these adobes will definitely not be able to bear their own weight.

But Wang Tian's method solves this problem very well, in fact, it can be used to build the wall directly with fired red bricks, but in this way, the temperature in the pavilion will be very high in summer, and the firing of red bricks also takes time and labor, so after a brief thought, Wang Tian gave up the idea of building a permanent wall.

The second brother of King Kong was in charge of the renovation of the pavilion, and Wang Tian then led Dashou, Kuroko, Zhou and others to start the preliminary refining of malachite, and fired the broken malachite with fire, like burning lime, but in this way it will be copper oxide.

After the calcination of the fire, the beautiful malachite turns into small black particles like coke, and after some water and impurities are burned off, these are left with relatively high purity copper oxide.

After crushing it, it becomes a black copper oxide powder, and then the charcoal, which is used as a reducing agent, is also crushed, and the two powders are thoroughly mixed.

The next step is to put it into a graphite tong pot for refining, and with the reducing effect of charcoal, pure copper can be extracted from copper oxide.

However, the mixing ratio of reducing agent and copper oxide is still unclear, and it needs to be experimented step by step, because if more reducing agent is put in, not to mention the waste of materials, the extra residue needs to be separated from the melted copper water, and it also takes a lot of effort.

A few people who followed the Son of Heaven saw that the Son of Heaven asked everyone to burn stones, and they all showed doubts, there is still lime in the tribe, can you use these stones that have been transported back to the tribe with hard work to produce?

In everyone's eyes, they have seen the situation that limestone will turn into lime after firing, and everyone takes it for granted that malachite will also turn into white lime after firing.

But when the results appeared, everyone became surprised, and Zhou on the side began to think that the products fired from different stones would not be the same.

These two products, one black and one white, have attracted his great attention, and he has decided to burn and try all the stones he can get.

It is precisely because of his idea that the Tianlong tribe will leapfrog from the Bronze Age to the Iron Age in the future, which is not mentioned for the time being.

The preliminary calcination and crushing of malachite, Wang Tian handed over to the big hand to be responsible, Wang Tian took Zhou and Heizi to start building a stove, and now there is a natural pure copper at hand, only need to purify the preliminary purified tin metal simply, and the bronze alloy ratio experiment can be carried out.

Related tools, such as graphite tong pots, newly improved leather blowers, etc., have already been made in the early stage, and several people use rod scales to weigh different weights of copper and tin, and then put in several graphite tong pots for fusion, and record the relevant data.

Then the obtained alloy solution is poured into a simple rectangular mold, smelted into a long bronze square, and after cooling, it is beaten, bent and broken, sharpened and so on, and the ratio of bronze alloy for different purposes has been tested.

This simple mold is only for experimentation, so it's very simple to make, and it's not a tool or weapon.

In this process, in addition to a group of dogs and little tigers following Wang Tian, Yun'er also curiously pulled Ling'er to watch together.

The two girls were very curious and shocked by the fact that the two girls were very curious and shocked by the fact that the two colored stones turned into liquid after being burned in a container for a while.

Xiao Ling is better, after all, he has seen the process of making a metal axe, but the shock in the lark's heart cannot be described in words.

I never thought that these "stones" could be melted so easily, and looking at the bright red and gorgeous metal solution in the tongs pot, my face actually showed the expression when I saw the malachite pendant.

Wang Tian has already understood what she thinks in her heart, sure enough, it is the nature of girls to love beauty, in the face of such a hot alloy solution, women think of decoration, Wang Tian can only admire their big hearts.

There was still a metal to make a few ornaments, but there was no need for alloys, so he handed over the task of figuring out the ratio of bronze alloys to Zhou, and began to figure out what kind of ornaments to make to please the beauties.

Wang Tian naturally doesn't know the craftsmanship of forging ornaments, but as a designer, he can use molds to mass produce.

It's just a few trinkets, and it doesn't take much time, it's just a matter of making clay blocks out of some clay and carving them into the shape you want.

After glancing at the slightly monotonous style of the two girls and the empty earlobes, Wang Tian decided to create two pairs of earrings first, two step shakes and a few rings.

It is still personalized and tailor-made, Wang Tian decided to create two sets of lark-shaped and lark-shaped earring pendants and step shake out, so that the two girls can be regarded as having a complete set of accessories that match their names.

As for the ring, Wang Tian doesn't plan to get any tricks, a bare plate is fine, so that it can better reflect the metallic luster of pure copper, as long as the person who wears it can raise it, there is no difference between pure copper ornaments and pure gold.

So all the people in the tribe were busy, but Wang Tian worked so hard, but he only smiled for the two little beauties.

Carving such a small mold is a slow process of meticulous work, fortunately, the volume is not large, and it is to please the two girls, Wang Tian does not feel boring to do it.

So, the two girls, five little wolves and two little tigers stood quietly aside, watching the Son of Heaven holding a knife and carving carefully against the pieces of dirt with a focused expression.

Yun'er suddenly appeared in her heart, it turned out that this nasty guy, when he was seriously focused on something, looked so charming, especially when he learned that he worked so hard, just to make beautiful decorations for himself and please himself.

A sweet feeling welled up in her heart, this sweet mood had washed away the little sorrow she had when she was separated from her people this morning, and the woman had no resistance to this kind of pampering and cherishing flattery.

Wang Tian didn't know at this time that with his face and the appearance of serious work, Yun'er, who had died, had a better impression of himself.

If he knew, his heart might swell, and after a morning of continuous efforts, several sets of molds had been made, just waiting for the afternoon to pour the smelted pure copper metal solution into it.

At this time, the ratio of copper alloy copper and tin for various purposes was also experimented by the greatest Ming family of the tribe of Zhou in the future, and the data recorded by him was handed over to the Son of Heaven.

Wang Tian glanced at it, nodded and asked him to archive and preserve it by himself, and reminded him to continue to refine the determined proportion range in the future, and strive to find a more allocation ratio.

You must know that the various bronze sword casting processes unearthed during the Warring States Period, even under the high-tech test conditions of later generations, there is no way to completely crack it, and only through continuous efforts and creation, it is possible for civilization to continue to progress......
