Because of the shouting of the two old men who were guarding, the people in the tribe who had no work to do for a while came to see the excitement, and they couldn't understand it, but they were curious about what the god leader was doing? Gu Yuan was loading the kiln, and the larger jars and basins were all upside down on the bottom layer, followed by pots, bowls, basins, and jars, which filled the kiln with great vigor, and lit a fire in the fire pit.

The kiln burned until midnight, the fire stopped in the second half of the night, Gu Yuan went to sleep, and when he came out of the kiln the next day, it was the most exciting time for all the people to fall, when Gu Yuan took out the first bowl, he was scrambling to take it to hold water to drink, and after drinking the water, the old man of the tree was so happy that he danced and cried!

Gu Yuan didn't know, but he did, and he translated to Gu Yuan that the tree regarded this earthen bowl as a treasure given by God to the tribesmen, a treasure that could be exchanged for meat, food, salt, and population!

"Changing the population......? Can the salt be changed?" and several old men and ladies nodded their heads again and again, "Yes! They told Gu Yuan that not only the pottery bowls and salt that can hold water can be exchanged for people, but even the bamboo tubes, wooden basins, and stone basins can also be exchanged!

"Hehehe! So our bows and arrows, meteor hammers, and slings can also be replaced?...... However, all military supplies cannot be exchanged!"

In one go, Gu Yuan burned two kilns of pottery, and taught the techniques to a few old people led by the old man from beginning to end, and the work of this kiln was taught to the old man in the future, he took four old men, and he was the leader of the pottery group.

If the pottery is successful, it can be exchanged, but with the good things in their possession, their protection naturally becomes a big problem. If you have a particularly good thing, including a person, but you don't have the power and strength to protect it, then this good thing will bring you pleasure and disaster!

The next step is to smelt copper and iron to make weapons. First take out the coal from the east, and then burn a batch of charcoal to come out. The technical content of this soil method of burning charcoal is not high, make a large firewood pile, paste thin mud outside, leave a few air holes up and down, light a fire from the hole, burn and burn, and wait for the fire to burn to the bottom hole, and then seal all the pores, that is, let the firewood simmer in a lack of oxygen inside, and wait until when the fire is naturally extinguished and cooled down, charcoal will become!

Then the termite nest soil and Guanyin soil were mixed and milled, evenly mixed into mud, and then several crucibles and long spoons were pinched out for later use to purify and make alloys. Then the mold is made of refractory clay, that is, the grooves of the copper and tin are cast, and after the copper and tin are cast, you can adjust the ratio of copper and tin to refine what tools you want to make!

In one fell swoop, after cooling, Gu Yuan weighed a few pieces of copper and tin, and his heart was surging, this bronze alloy technology is widely used in history, because this metal has a low melting point and is easy to cast, so it has become the earliest metal casting technology mastered by mankind.

Of course, the ratio of alloy is very particular, the copper and tin content is only 1:1 ratio when making copper mirrors, and the higher the copper content, the more ductile the bronze, and the more yellow the surface color. What Gu Yuan is preparing to build now are axes, spearheads, horse chews, zigzag ploughshares, etc., as for knives, swords, arrow clusters, etc., we will talk about it later.

The "lost wax method" casting mold was the complete process that Gu Yuan saw with his own eyes in a mountain township farm tool factory, so although he was not skilled in operation, it could be completed.

The first ones to come out of the mould were all axes, all the size of an adult's foot, each shining with a pale golden light, and each with a reserved socket hole.

"Huh......? What kind of treasure is this, Chief?" Shan's loud voice attracted almost all the people at home at once, and Gu Yuan knew in his heart that the best way to make them accept these new things as quickly as possible was not to explain but to practice.

Gu Yuan first casually found a wooden stick and inserted it into the reserved hole of the axe, and then raised it and cut it at the root of a tree with the thickness of a child's arm, and the small tree broke off in response. Reverse the axe, and throw it at a stone, "bang" the stone is shattered, and the axe is naturally intact!

"This is wonderful! It's beautiful and practical! It's better than a stone axe, it's a god, isn't it?"

"This is an artifact created by the god leader with a spell! In the future, it will be easier and faster to cut down trees!"

"Cut down trees with this thing? What a talent! This can kill enemies and demons!"

Everyone talked about it, and Gu Yuan immediately asked Shan Heshi to find a few wooden sticks of suitable thickness and sturdy, loaded each axe with a handle, and then polished it with stone, and the axe blade was much sharper than the stone blade without grinding. It will be much more convenient to cut and build wooden things in the future.

Then, Gu Yuan cast the spear head, so that everyone in the guard of the God Tribe had a handy spear, and then cooperated with the bamboo head shuttle dart, which enhanced the combat effectiveness of close combat!

Ploughshares, copper shovels, shovels, and horse chews were also cast.

In the process of using these bronze tools, Gu Yuan improved the furnace and began to smelt iron ore, and he also knew some of the steel-making techniques, and he could explore the operation. This time, Gu Yuan consciously began to train a few assistants, eight young men and women, including mountains, stones, hands, eyes, and ears. Gu Yuan taught them a full set of smelting and casting techniques.

Hundred steels were also successful, and Gu Yuan forged steel knives, steel swords, steel forks, etc., as well as shovels, shovels, iron claws, iron wires, and so on. The military strength increased greatly, and Gu Yuan set about building a strong cavalry force, no longer using infantry.

The unit was named "Shenwei Battalion", Gu Yuan served as the battalion commander, and there were five companies under it. In fact, there are only 100 people, 20 people in a row, and almost all of them are women. The reconnaissance company is closely connected with the bird flock of the bird king, and is mainly responsible for reconnaissance and transmitting all kinds of information, the company commander is the cloud; the combat company is responsible for storming and defeating the enemy, fighting on a large scale, and closely cooperating with the brute dragon group, the company commander is a young man named Big Foot; the guard company is responsible for the security protection of the headquarters and leaders at all levels, and the company commander is smoke; the logistics company is responsible for military transportation and care, and the company commander is the moonlight; the general affairs company is responsible for the coordination, assistance, substitution, rescue and other roles in all aspects, the company commander is a young man with a wooden stake, and the young man is very clever!

Gu Yuan left four personal guards around him: mountain, water, fingers and thighs, and when he went out to fight, he was protected by the Barbarian Dragon Queen and her four guards, a total of five big barbarian dragons!

In the process of intensive military training, Gu Yuan came to a long-distance "military training", and went to Caishan to transport various ores and clays. This time, Gu Yuan smelted and cast a special thing, a brass hairpin that pulls his hair. In addition to himself and all the children before the age of 10, Gu Yuan built one hundred and thirty-six copper hairpins. Let the man pull up all the hair, let the woman pull up most of the hair, and scatter a small part on the back of the head, like a small black waterfall, which matches the bangs on the forehead, making the woman more like a woman.

"Chief, the Night Witch asked me to give you something!"
