Everyone's excitement was best expressed by the two beast-eared girls, Yan Lin and Xing.
Before Yang Cheng could speak, the two of them shouted:
"Witch, what is that and where is it?!"
Yan Lin and Xing felt extremely happy. There were new things to see every day.
The witch made ramie cloth a few days ago, and now the witch is going to make another very powerful treasure!
"Haha, I haven't done it yet, how could it come out?"
Yang Cheng laughed, rubbed Yan Lin's tiger ears vigorously, and touched Xing's little rhino horn.
He called to everyone: "Okay, we'll talk about the new stuff later. Let's go back to the tribe to eat and pick up the pieces for the expedition!"
It was no surprise to everyone that Yang Cheng would pop up four-character idioms from time to time.
But as soon as they heard that they were eating, these primitive people suddenly became greedy. They all responded excitedly and rushed towards the canteen in a mighty and boundless manner.
The return of the expedition team was something worth celebrating, so everyone in the Qingque tribe started to have fun again. They stopped doing any work in the afternoon and just ate boiled meat and barbecue next to the canteen, jumping and dancing.
In response, Yang Cheng sighed.
People in this tribe find reasons every day, saying that they want to celebrate, dance, eat meat and rest instead of working. How will the Qingque tribe develop...
Joy belongs to the tribe, and as their shaman, Yang Cheng began to think about how to make wheels.
"The wood is straight and the rope is in the middle, and the frame is used as a wheel. Its curves are regular. Although there are some violent twists and turns, the wood is no longer straight, and the frame is used to make it so."
Yang Cheng held his head and remembered what Xunzi said.
To put it simply, wood is heated with fire to make it bend.
But how is this a crooked way?
Yang Cheng tried hard to think of TV shows, movies, long videos, short videos, etc. about wheels in his mind, and tried to remember the structure of ancient wheels.
While thinking this, Yang Cheng took a wooden stick and started drawing on the ground.
after a long time.
Yang Cheng determined that a wooden wheel seemed to require three structures.
The first structure is the outermost part of the wheel, called the "rim."
The rim is the outer circle of the wheel, similar to the rubber tires on various vehicle wheels on the earth.
The second structure is the middle part of the wheel, called the "spoke."
The spokes are similar to the iron bars in the middle of today's major wheels, used to stabilize the structure of the wheel.
The last kind of connection is the innermost part of the wheel, called the "hub".
The hub is the log in the center of the wheel, which serves as a fixed support.
"Well, it should be these three structures. They should come one after another now."
Yang Cheng tapped the wooden stick on the ground, thinking it was time to start trying.
"When making a wheel, you must first make it from the inside out, so that you can determine the size of a wheel."
Yang Cheng plans to start from the innermost "hub".
Because it was the first time to make wheels, Yang Cheng felt that it was better to play it safe and did not plan to make very large wheels first.
Yang Cheng found Hongya and handed him a wooden stick: "Go and find a tree as thick as this."
This was not the first time that Hong Ya was ordered by Yang Cheng to look for trees. Knowing that Yang Cheng was getting something again, she took the wood and turned around without asking any questions.
But just after taking two steps, Yang Cheng suddenly thought of something again and shouted behind him:
"etc."
Hongya turned around in confusion and asked, "Wu, is there anything else?"
Yang Cheng nodded and said: "Look for more trees, all kinds of trees."
"Okay, Wu."
Hongya responded and found a few more totem warriors.
There are still some reliable people in the tribe. When Hongya called out and heard that it was Yang Cheng's order, these totem warriors immediately gave up and jumped up and down, following Hongya, running away in a hurry.
An hour passed.
Each of these totem warriors came back carrying more than ten trees.
Five or six people dropped more than fifty or sixty trees in front of Yang Cheng.
Such a big movement suddenly attracted everyone's attention, and many people stopped dancing and looked over.
But when they saw Yang Cheng standing here, although everyone was curious, they didn't come to ask - after what happened with Ramie Bu, everyone could barely "control" themselves and not disturb Yang Cheng's work.
"Witch, this is enough. If it's not enough, let's chop some more." Hongya said with a smile.
The increase in totem levels and the emergence of bronze axes and bronze machetes made cutting wood not too difficult for the Qingque tribe.
In the past, the workload of these fifty trees was enough for all the totem warriors of the Qingque tribe to work for a whole day.
But now, it only takes more than an hour, less than two hours of work, and it is still completed by five or six people.
Looking at the trees filling the open space in front of him, Yang Cheng twitched his lips and said, "Well, that's enough, that's it. You can stay Hongya, and you can go and do the rest first."
The remaining totem warriors also wanted to stop and see how dare the witch wanted to be, but since the witch said so, they did not dare to disobey the order, so they agreed and went down.
After they left, Yang Cheng looked back and forth on the more than sixty trees, and finally selected seven or eight trees and said to Hongya:
"Red Fang, remove all the branches on these logs, and then cut them off from here, just like this."
Hongya followed Yang Cheng's instructions and cleared away all the branches. Then he took a bronze stone ax and cut it into two pieces at the place marked by Yang Cheng.
The first step to making wheels is to make the wheel hub. The production of the wheel hub is quite simple.
However, not every wood is suitable for making wheels.
Because some wood materials are soft and not hard enough, while some wood materials are hard but inelastic.
To make a suitable wood for making a wheel, it actually needs to be hard but not lose elasticity.
Yang Cheng had only seen it on TV and didn't know which kind of wood to use.
But that’s not a problem. Primitive society lacks everything except wood, and totem warriors are strong enough to do things without getting tired.
Experiment a few times and you will know which wood is suitable for making wheels.
After the wood is selected, it’s time to process it.
This step is also relatively simple. Yang Cheng first calculated the average diameter of the wood, then took out a thin wire made of ramie and straightened it, and then used a compass to draw a circle on the cross section.
The circle is the cross section that Yang Cheng wants to cut. This is to first make the general shape of the wheel hub.
The next step is polishing.
This is pure benchwork work, without the help of machinery. It requires manpower to poke it out one by one.
Yang Cheng tried it a few times himself, but was exhausted and then gave up.
