The blood has been taken, and the casting of the bronze ware has begun soon.●⌒,

They don’t know how long the blood in the bamboo tube will exist, nor can they guarantee whether the animal blood will deteriorate. Therefore, all preparations will naturally be faster, the better.

In the casting room, irrelevant people were forcibly driven out. Even if they wanted to see it, they could only wait outside. Except for the two leaders and three big leaders, the other small leaders could only circle outside and stretched their necks and couldn't see a shadow.

The casting of copper ware is also a method of pouring molten alloy liquid into the casting cavity using the clay casting method used by slave owners.

Most of the casting materials are clay materials, but this time the casting is different from before, and everyone is becoming more cautious in dealing with each process.

This is an attempt to use the blood of the green face and fangs, and is an important turning point. If successful, the bronze ware used by the tribe will rise to a level in the future, and the use of stone tools will be gradually replaced. After all, if the new bronze ware is hard enough and sharp enough, even as Gong Jiaheng said, it can break the hard stone, many people will choose bronze ware.

The cast clay materials are all clay materials after long-term drying and repeated beats to make them highly cooked. The copper ware made in the past has also proved their usefulness. They will not be too wet or breathable. The copper ware is still good.

This time, the clay used is more stringent in sieving, rinsing, and other processes.

The ore smelting process is still the same as before, but when the black and turbid air, yellow and white air, and the green and white air is finally left, the copper alloy is completely melted and can be melted and cast according to the previous process. However, this time, the blood of the green-faced and fangs will be added before casting.

When did the words Shao Xuan see on the wall of Gongjia Valley write about when the beast blood was added, but did not explain the details in detail. Shao Xuan could only try based on his own guesses.

Remove the needle on the "syringe". Green blood flows out from the bamboo tube where the needle is connected, making a hissing sound.

"Just... just drip like this?" The craftsman next to him was so nervous that he stuttered.

Otherwise what else can it be?

Shao Xuan couldn't find someone from Gongjia's family to come and ask. He could only try to pour it in.

Shao Xuan raised the bamboo tube, letting the animal blood in the tube drip out of the small hole connecting the needle and fall into the molten copper alloy liquid.

The green blood with hissing sound made everyone staring at this side feel as if they were being roasted on a hot stone slab.

I was nervous and anxious, and I was stiff all over and didn't dare to move around, nor did I make any noise, for fear of interfering with the movements over there.

The blood dripped into the copper alloy liquid, and the hissing sound stopped abruptly, and did not evaporate as Shao Xuan and the others thought, but spread out in the alloy liquid like a smudge.

As the blood gradually dripped, a cyan flame suddenly emerged from the alloy liquid. The flame body was not high. It was close to the liquid level of the alloy liquid, and it was only a layer less than the height of the little finger.

The fire is still there, and the alloy is still melting.

The blood dripped in the bamboo tube more and more, and the liquid level of the alloy liquid was covered with a layer of cyan flame. At the same time, the alloy liquid inside was rolling, but no bubbles appeared, only the cyan flame that was constantly burning.

The color of the alloy liquid is changing, becoming darker, and is no longer golden. The color becomes even as the alloy liquid rolls.

When the animal blood is used up and there is no animal blood dripping again, and the blue flames in the alloy liquid gradually disappear, pour the casting mold.

Outside the casting house, the little leaders such as Mai, Tuo, Xiang Chen and others who knew the secret of the golden utensils were waiting outside, wanting to hear the sound inside to satisfy their curiosity. However, so far, there is nothing they want to know inside.

The two leaders were too calm, even if they were screaming, it would be better than keeping silent.

After a long time.

The sound of forging came from the room.

Forging, engraving, annealing, grinding...

Although everyone was very nervous, all the work was going on. Apart from the assignment of tasks, no one asked or said more. The two leaders also became the background, just staring at the wide copper knife that had been roughly formed there.

The knife looks a little rough now and does not have much beauty, but in the eyes of the people in the house, it is simply a peerless beauty.

It is different from the previous bronze ware. Even if it has not been completed, it gives people the feeling of a different realm and an existence of another level!

...

In the sky outside the house, the sun hangs from high to deflection.

At dusk, the afterglow of the setting sun scatters everywhere, and the shadows of those waiting outside are stretched out.

Inside the house, Shao Xuan held the newly cast copper knife and wiped the blade with his animal skin.

The biggest difference between this knife and the most conspicuous thing about the copper ware used to be ware of its color.

It is not golden yellow, nor is it the silver-white, silver-gray or even reddish color of other alien bronzes, but cyan!

The domineering broad blade body, dark green color, restrained, but fierce.

Shao Xuan stared at the blade's pupils, and the cold light reflected from the blade was reflected. He threw away the wiped animal skin, wandered along the edge of the blade, and then flicked it gently.

It was like the howling sound of the wind, and there was a tremolo of a sharp blade shaking. It felt like something was charging in the blood.

Cyan bronze ware!

Most bronze ware only turns blue after rusting, but now, this newly cast copper knife is introverted and deep dark blue!

Has it been successful?

This is the question everyone wants to know.

The leaders and the big leaders knew nothing, and only Shao Xuan and the craftsmen who were responsible for the pounding and engraving just now knew that this knife was much stronger than other bronze ware!

Shao Xuan's gaze moved away from the sword and looked at Ao Hezhengluo who had been standing next to him without making any noise.

The two leaders were not in a hurry, but they were too nervous and too expectant to react. Now, seeing Shao Xuan look over, Ao quickly took out a stone as big as a fist and threw it up. This is one of the test stones in the stone chamber. This piece belongs to the medium-sized stone level. For ordinary bronze ware, medium-sized stones will be used. After all, ordinary bronze ware has limited sharpness and hardness, so it cannot be forced.

Because he was too nervous, Ao Baoshitou's movement seemed very stiff. But at this time no one cared about Ao Baoshitou's movement. He stared at the thrown stone, looked at the knife in Shao Xuan's hand, and his eyes swept back and forth quickly, for fear of missing any detail, and at that moment, he forgot to breathe.

Shao Xuan held the bronze sword in both hands, took a step forward, raised it, and then cut it down towards the stone thrown into the air!

Bang!

The blade slashed hard on the stone, and the stone as big as a fist broke into two halves, simply, neatly and smoothly!

And there was no trace of curl on the blade.
Chapter completed!
