The Caveman Made Me Awesome

? Xicheng found azurite mine very early.

The color of azurite is very bright blue, accompanied by more beautiful malachite, which is very conspicuous. Some tribes in Xicheng like to grind them and process them into pigments. The ore was brought back to Xicheng.

So since azurite was discovered long ago, why didn't Xicheng start copper smelting earlier?

Because just having this copper mine is not enough.

The hardness of pure copper is not high, and it cannot be made into weapons at all. It has no practical value for primitive people, and the real value is copper alloy.

For example, brass is an alloy of copper and zinc, and bronze is an alloy of copper and tin. To smelt bronzes with high hardness, tin ore must be found.

Fortunately, before the winter of last year, Chief Youshi finally found tin ore in the south - this kind of tin ore has obvious characteristics, with a metallic luster, Ye Xi recognized it at a glance, and happily rewarded Chief Youshi with a piece of gold on the spot. Breed nucleus.

After the copper ore and tin ore are found, the copper smelting work can be carried out.

Ye Xi decided to use the fire method to smelt copper, first of all, to build a charcoal kiln.

He led the tribe to build five giant charcoal kilns with stones and cement in the back mountain.

These charcoal kilns are bulging like yurts. They look naive, but they are very effective. A steady stream of wood is sent to these charcoal kilns, and with the continuous white smoke rising from the holes of the charcoal kilns, charcoal is also formed in large quantities.

After getting out the charcoal, Ye Xi went on to build two big furnaces for smelting copper and tin.

Pieces of copper ore, tin ore and charcoal were sent into the smelting furnace, and pieces of slag-like copper and tin were sent out.

These copper and tin nuggets are doped with impurities and need to be further purified, and because tin has a low melting point, the purification work is relatively easy, while copper has a high melting point, so it is somewhat difficult to melt.

Ye Xi was stuck there for a moment.

Knowing Ye Xi's difficulty, Mianji eagerly wanted to help. The flame of Mianji was so hot that it could melt copper, but Ye Xi knew that relying on Mianji was not a long-term solution, so he refused it without hesitation. In a few days, I designed a more scientific large-scale furnace, and tried to build an original large-scale blower to increase the temperature in the furnace.

Finally, the copper was also successfully purified.

Then making bronze is very simple,

Just add tin to pure copper,

Let the two be fully mixed to get the bronze liquid, and then make a mold base and pour it directly with the bronze liquid.

In fact, although the above-mentioned bronze smelting process is simple, it is very difficult to operate in practice.

For example, the person in charge of burning charcoal always forgets to hold his breath when taking out the charcoal, causing carbon monoxide poisoning. For example, the crucible in the furnace is too hot to take it out, and it is solved by grinding out a hook-shaped thin stick with a hard stone tool. this problem.

In addition, the amount of tin contained in bronze has the highest hardness. If other metals are added, whether the bronze will be harder or not is a question that needs to be further explored.

...

Ye Xi first poured a giant mace with bronze liquid.

It was a heavy bronze mace with sharp thorns on its head and taller than a person. It would be very difficult for ordinary people to lift it, but all Xicheng warriors went crazy.

Because this strike weapon is so in line with the aesthetics of primitive people!

They just love weapons of direct violence! All stone rods, stone hammers, fish bones and rods are all scum in front of it!

Under the jealous eyes of everyone, Yong finally got the mace.

From then on, Yong gave up his original weapon and switched to a bronze mace.

When hunting, Yong just swung the bronze mace so high, slammed it hard on the head of the beast with a bang, and then crackled, the skull of the beast was smashed to pieces, and even the brain inside the skull was smashed. The long thorns on the mace pierced through, and he couldn't die anymore.

When you see a fierce beast, give a stick with a slam, and when you see another beast, give another stick with a bang. As long as the beast is not a particularly huge beast, you can get it all done with a stick, which is extremely brutal.

Yong smashed heartily, exhilarated, never felt so refreshed.

The others were envious and wanted the bronze mace too. Ye Xi announced to everyone, "Bronze ware is not easy to smelt. A bronze mace needs to be exchanged for a barbarian beast core or something of the same value."

Here we must mention the rules of Xicheng again.

The harvest obtained by the hunting team from hunting must go to the counting place first, and all the harvest will be counted by a special person. After counting and recording, half of the harvest will be returned to the hunting team, and the other half will be included in the city treasury of Xicheng.

As Ye Xi is the owner of Xicheng City, he has full rights to use this Xicheng stockpile, even if it is his private treasury.

Of course, he can't keep all of it for himself. Some of the materials need to be distributed to the staff of the public fire kitchen, some to the managers of the back mountain, some to the young tower, and some to the people working in the farmland...

With such a piece of distribution, the city treasury of Xicheng is not rich, and therefore, Ye Xi cannot give more generous benefits to the people working in the city.

On the contrary, the soldiers of the hunting team had a lot of money. When the storage room in the stone house was opened, there were so many animal skins, cores and meat that they could overflow.

So Ye Xi had to find a way to enrich the city treasury of Xicheng.

Now if the soldiers want bronzes, they have to exchange them with beast cores...

When the bronze industry in Xicheng was in full swing, the warrior who guarded Azhi in the deep forest suddenly came to Ye Xi's residence, knelt down in front of Ye Xi in shame,

"Master Xiwu, girl Azhi is gone!"

Ye Xi beside the stone table put down the charcoal pencil in his hand, his body froze.

The soldier didn't dare to raise his head, and continued: "The white cocoon didn't move all the time, but it suddenly opened this morning, and Miss Azhi got out of it... She wanted to leave, but I, I couldn't stop her, but she I was tied to a tree with silk, and I was not let down until the soldiers on shift came to report to you."

Ye Xi was silent for a moment, then asked, "Which direction is she going?"

The soldier replied: "It's heading north."

Ye Xi sighed, stood up and helped him up, and said, "It's not your fault that you can't see her, you should go down and have a good rest, you have worked hard these days."

The soldier blushed with shame.

Ye Xi didn't reprimand him, but it made him feel worse than scolding him. If it happened again, he would rather have an arm cut off by silk, and break free to stop Ah Zhi.

After the soldiers left, Ye Xi looked at the obese first-generation silkworm that was half the length of a human in the bedroom, remained silent for a long time, and finally called Chief Falcon over.

"Azhi is gone, I don't worry about her, you send a few stronger falcons to follow her all the way, and report to me anytime there is any situation!"

Chief Falcon took the order: "Yes!"

Ye Xi watched Chief Falcon leave before returning to the stone table.

He knew that Azhi was going to look for the Chongliu Tribe, and it was dangerous outside, and it would be safer to have a falcon following Azhi.

As for the matter of the first silkworm...Ye Xi was not sure that it could transform into a silkworm king with 100% confidence, and the feeling of dying hope was even more painful. This kind of pain might completely destroy Ah Zhi, so he weighed it for a long time, and finally decided not to tell her up.

In fact, it's good for A Zhi to leave, she is full of hatred in her heart now, and she won't be happy staying in Xicheng, instead, she can take a walk outside to relax a little.

But even though the reasoning is the same, Ye Xi couldn't help feeling sad when he thought of A Zhiyuan's innocent and bright smile.

Ye Xi, who was sitting by the stone table, adjusted his mood after a while, picked up the charcoal pencil, and continued to draw something on the parchment.

"rustle……"

Charcoal strokes on the yellowed parchment.

A closer look reveals that it is a majestic giant ballista.
