The Caveman Made Me Awesome

? Xicheng found the azurite mine very early.

The color of azurite ore is very bright blue, and there is also a more beautiful malachite in it. It is very conspicuous. Some tribes in Xicheng like to grind them and process them into pigments. Kind of ore brought back to Xicheng.

So since the azurite mine was discovered a long time ago, why didn't Xicheng start smelting copper early?

Because this copper mine is not enough.

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

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

Fortunately, before the winter last year, Chief Youshi finally found tin ore in the south. This kind of tin ore has obvious characteristics and has a metallic luster. Ye Xi recognized it at a glance and happily rewarded Chief Youshi with a piece of king. Kind of animal core.

After the copper mines and tin mines are all found, the copper smelting work can proceed.

Ye Xi decided to smelt copper by fire, first building a charcoal kiln.

He led his tribe to pour stone and cement into five giant charcoal kilns in the back mountain.

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

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

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

These copper and tin blocks are doped with impurities and need to be further purified. Because of the low melting point of tin, the purification is relatively easy, and the high melting point of copper makes it difficult to melt.

Ye Xi was stuck there for a while.

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

Finally, copper was also purified smoothly.

Next, making bronze is very simple,

You only need to add tin to pure copper and mix the two to get the bronze liquid. Then make the mold base and pour directly with the bronze liquid.

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

For example, the person in charge of burning charcoal always forgets to hold his breath when taking charcoal, which causes carbon monoxide poisoning. For example, the crucible in the furnace is too hot to take it out. Use a hard stone tool to polish out a hook-shaped stick. This question.

In addition, how hard is the tin content in bronze is the highest? If other metals are added, whether the bronze will be harder, this is a question that needs to be explored.

...

Ye Xi first poured a giant mace with bronze liquid.

This is a heavy bronze mace with a long and sharp head and taller than a human. It would be very difficult for ordinary people to lift it, but all Xicheng warriors are crazy.

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

They just like this kind of direct violence weapon! What stone rods, hammers, fishbone rods are all scum in front of it!

In the eyes of everyone's jealousy, he finally got this mace.

Since then, he has given up his original weapon and switched to a bronze mace.

When hunting, Yong picked up the bronze mace so high and slammed it against the head of the beast with a bang, and then crackled. The skull of the beast was smashed and even the brain inside the skull was smashed. The long thorn on the mace pierced through, and he could not die again.

Seeing a fierce beast, give it a stick, and then see a fierce beast, give it another stick. As long as the size of the fierce beast is not particularly huge, it will be done with the stick and it is extremely brutal.

Yong smashed so heartily, extremely happy, I never felt so refreshing.

Others were very envious and wanted this bronze mace. Ye Xi announced to everyone: "Bronze smelting is not easy. A bronze mace needs to be exchanged for a barbaric animal core, or something of equivalent value."

Here must mention Xicheng's rules again.

The hunting team must first go to the inventory point for the harvest obtained from hunting, and all will be counted by a special person. After the inventory and recording, half of the harvest will be returned to the hunting team, and the other half will be put into the Xicheng City Treasury.

As the lord of Xicheng City, Ye Xi can call this Xicheng inventory with full authority, even if it is his private library.

Of course, he can't keep all of them for his own use. Some of the materials inside need to be distributed to the staff of the public fire kitchen, some of the materials are distributed to the management staff of the back mountain, some of the materials are distributed to the young tower, and some of the materials are distributed to the personnel working on the farm...

With such a piece of allocation, Xicheng's city treasury is not rich, and therefore, Ye Xi could not provide more generous benefits to the people working in the city.

On the contrary, the hunting team soldiers have a lot of money. When the storage room in the stone house is opened, there are so many skins, beasts, and beasts that can overflow.

So Ye Xi wanted to find a way to enrich the city treasury in Xicheng.

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

When the bronze industry in Xicheng was in full swing, the warrior guarding Azhi in the deep forest suddenly came to Ye Xi’s residence and knelt before Ye Xi in shame.

"Master Xiwu, Miss Azhi, she is gone!"

Ye Xi next to the stone table put down the charcoal in her hand, her figure stagnated.

The soldier did not dare to look up, and continued: "The white cocoon has not moved, but suddenly broke open this morning. Girl Azhi got out of it... She wanted to leave. I couldn't stop me, but she was later caught I was tied to a tree with silk, and I was not put down until the soldiers in shift came to report to you."

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

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

Ye Xi sighed long, stood up and helped him up, and said, "It's not your fault to look down on her. Go down and take a good rest. You have worked hard these days."

The soldier flushed with shame.

Ye Xi didn't scold him, but made him feel more uncomfortable than scold him. If he did it again, he would rather be cut off by the silk, and break free to stop Azhi.

After the soldiers left, Ye Xi looked at the half-length fat first-generation silkworm in the bedroom. He remained silent for a long time before calling Chief Falcon over.

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

Chief Falcon took orders: "Yes!"

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

He knew that Azhi was looking for the Chongliu tribe~www.NovelMTL.com~ It was dangerous outside, and it would be safer to have falcons following Azhi.

As for the first generation of silkworm... Ye Xi was not sure that it could be transformed into a silkworm king 100%. He hoped that it would be more painful to die. This pain may completely destroy Azhi, so he weighed it for a long time and finally decided not to tell her. Up.

In fact, whether Azhi leaves, she is full of hatred in her heart now, and staying in Xicheng will not be happy. On the contrary, walking outside can be a little relieved.

However, although the truth is the truth, Ye Xi still feels sad when he thinks of Azhiyuan's innately brilliant smile.

After sitting at the stone table, Ye Xi adjusted her mood for a while, picked up the charcoal pencil, and continued to concentrate on drawing something on the parchment scroll.

"rustle……"

Charcoal strokes on the yellowed sheepskin roll.

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