When Yanhu and Cangshi searched for vines, tied the wheel with vines, tied one end to a wooden stake by the river, and threw it into the river.
Yang Cheng guided Lulu to make a round mold out of clay.
After Yanhu and the others came back, the mold was almost finished.
Yang Cheng pointed at the copper ore and said:
"I'm going to make something out of copper ore later, and I need your help. This thing takes a lot of time, so you have to do it carefully."
"Yes, Wu."
Everyone responded quickly.
Yang Cheng nodded, and the witch power in his body was excited.
"Pyromancer!"
A fierce, hot flame burst out from Yang Cheng's palm.
Although the flames released by the fire technique are not as big as those released by Yang Cheng before, the flames are bundled together with blue light. Anyone who looks at it can see that the fire technique released by Yang Cheng is more powerful than the previous flame technique. . he
Yanhu and the others couldn't help but take a step back and looked at each other, each secretly feeling frightened.
"The witch's witchcraft has become even more powerful."
After releasing the flames, Yang Cheng warned again: "Okay, you guys prepare the small copper hammer I made before, and you will hit wherever I ask you to hit later!"
After saying that, Yang Cheng stopped talking nonsense and started to melt the copper ore with flame magic.
It is better to melt the copper ore into copper juice first, and then slowly put it into the mold that Yang Cheng asked Lulu to make.
The shape of the mold is very simple. It is a large circle with the same diameter as the wheel. It is composed of two layers connected together. One side is sealed and the other side is not sealed.
The copper juice is poured from the unsealed side and fills the entire mold.
After cooling slightly, Yang Cheng smashed the mold made of clay, and obtained a thin round copper sheet.
However, due to the uneven heating due to the soil, although the outer surface of this round copper sheet is completely round, there are some places that are sunken and some places that are convex inside.
At this time, someone needs to knock on it.
"Yanhu, knock that place out and use a little force."
"Cangshi, that place, yes, that's where it is. Knock it in a little, but keep it smooth like the rest."
…
"Bang Bang Bang..."
"Pa bang bang..."
Under the command of Yang Cheng and the hard work of everyone, a round copper sheet with a fairly perfect arc was successfully made.
Yang Cheng calculated the time and found that it took more than an hour to make the copper skin. The wheels should have been soaked in the cold river water.
"Yanhu, go get a wheel and come back. Go quickly and come back quickly. The sooner the better!"
Yang Cheng said to Yan Hu, and at the same time, he made the temperature of the flame technique smaller and kept the round copper skin in a burning state.
The fifth-grade totem warriors from other families are fighting ferocious beasts in the wilderness to hone their energy and blood, or they are hunting higher-level ferocious beasts to provide extra food for the tribe.
The fifth-grade totem warrior of the Qingque tribe spends his days doing chores.
If I'm not doing carpentry, I'm blacksmithing.
But don’t tell me, it’s pretty useful.
The open space is about three to four hundred meters away from the river. On earth, running back and forth would take at least more than a minute. Many adults may not be able to complete this back and forth in two minutes. 800 meters to run.
However, Yan Hu, who is a fifth-grade totem warrior, took only more than thirty seconds to carry back the wet wheel that was still stained with water.
The wheels are made of hard, strong wood.
It was one meter tall and weighed as much as two or three adults. Yan Hu carried it back, not only his speed was not affected at all, but his face was not red and his heart was not beating.
Yanhu said: "Witch, I brought the wheel."
Yang Cheng pointed to the open space next to the round copper sheet and said, "Put it there."
After Yanhu put down the wheel with water, Yang Cheng said again: "Here, you two put the round copper sheet on this wheel and cover the wheel."
This is not a difficult matter for the totem warrior.
The copper skin has cooled down a lot. It is not like the copper juice at high temperature at the beginning. Besides, the totem warriors do not directly take the copper skin with their hands. Yang Cheng specially prepared two things for them.
One is a bamboo strip, but it is a bamboo strip that Yang Cheng has baked using flame magic. The middle of the bamboo strip is bent and the two ends become parallel, just like the tongs used to pick up vegetables when eating Malatang.
The other one is animal skin, which can be wrapped around the hands to insulate them from heat and prevent them from being burned.
However, the difficulty is not difficult, Cangshi frowned slightly and hesitated:
"Witch, it seems like it can't fit in. Isn't this round copper plate the same size as the wheel?"
Cangshi saw clearly just now that Yang Cheng used the diameter of the wheel to make a straight bamboo strip, and then used this straight bamboo strip to bake the round copper skin.
Cang Shi could see clearly when he was beating the round copper sheet just now. After beating for a while, Yang Chenggong put a straight bamboo strip in the middle of the round copper sheet to determine the diameter of the round copper sheet.
Yang Cheng laughed: "Haha, Cang Shi, don't worry, just listen to me. If I say you can get in, you can get in!"
Yanhu on the other side also spoke: "Cangshi, why do you think so much? Wu said it can be trapped, so it will definitely be possible."
After hearing this, Cangshi stopped talking.
Since Yang Cheng lied, he would lie.
Anyway, if there is a problem, the witch will solve it.
So, Cangshi and Yanhu held it up with bamboo strips, and grabbed it with hands covered with animal skins, and placed the heated and slightly red round copper leather ring on the wheel.
"Take this side first."
Yang Cheng asked the two of them to put on one side of the wheel first, and then said: "Yes, that's it, and then put on this side."
If one side is hooked, this side should not be hooked, right?
Cang Shi thought so in his heart, but still listened to Yang Cheng's words and put the round copper sheet on his hand onto the wheel.
Something shocking happened to him!
The copper sheet, which is exactly the same size as the wheel, actually covers the outside of the rim, and it fits perfectly.
How can it be?
Isn't this round copper ring the same size as the wheel?
Cangshi was amazed. He saw clearly that they were all measured with the same straight bamboo stick!
"Quick, don't be stunned!"
Yang Cheng urged: "Bring cold water and pour it on the round copper leather ring."
"oh oh."
Cangshi came to his senses, responded hurriedly, took the cold water that had been prepared from the side, and poured it on the round copper ring.
"Zizzizi..."
The sound of cold water rushing sounded, and streams of water vapor floated up.
Under the stimulation of the cold water, the round copper leather ring cooled quickly and was tightly tied to the rim.
Seeing this scene, Cangshi suddenly remembered that when mining stones before, witches also used this mysterious witchcraft called "heat expansion and contraction"!
