Everyone's hesitation and confusion were what Yang Cheng had expected.
Yang Cheng smiled and said: "Haha, of course a person wouldn't be able to jump up if he jumped so directly, but have you forgotten what tool we used when we were building the house?"
The biggest difference in IQ between humans and animals is that humans can make and use complex tools, while animals can only use simple tools at most.
Hear what Yang Cheng said.
What tools do you use when building a house?
The totem warriors of the Qingque tribe lowered their heads and began to think, while the totem warriors of other tribes looked confused.
houses? What is that and can it be eaten?
"Wu, are you saying we can make ladders?"
Cangshi thought of something, his eyes brightened, but then his eyes dimmed, he shook his head and said: "Witch, the ladder doesn't work, it's too short, this mountain wall is too high."
"Yes, that's right, it's the ladder!"
Yang Cheng smiled and said: "Hahaha, Cangshi, don't worry. Although this mountain wall is very high, it is not so high that even a ladder cannot go up. One ladder will not work, but if we put many ladders How about connecting them together?”
"Many ladders connected together?"
At this moment, not only the Cangshi lit up, but the other totem warriors of the Qingque tribe also followed Yang Cheng's words and thought of the scene of connecting many ladders together.
Two totem warriors on a ladder are about the same height, and there are about 13 totem warriors on this cliff. If you want to climb this cliff, you can only build seven ladders at most!
"It's true. Why didn't I think of just connecting the ladders together?"
"Wu, you are so smart!"
"Oh, just make a ladder and climb up!"
"Why didn't I think of such a simple thing?"
…
Everyone was excited and clapped their heads in regret. It was Wu Lai who came up with such a simple thing every time.
Although Wu was in charge of this, they also wanted to help.
Of course, this is only the idea of a few totem warriors. Most of them still think that witches should do this kind of thinking.
Among them were two girls with animal ears, one on the left and one on the right, holding Yang Cheng's arms, with stars in their eyes and admiration on their faces.
The people in the other tribes were so confused that they couldn't understand what Yang Cheng and the others were talking about.
Why, after Yang Cheng said that he could use the thing called the "ladder", the group of totem warriors of the Qingque tribe suddenly felt happy and annoyed at the same time.
What exactly is this thing called a "ladder"?
Yang Cheng didn't let them wait any longer. Soon, the answer would be revealed.
To build a ladder, there are two main materials used, one is wood and the other is rope.
Wood is easy to find, just cut down the trees nearby, and rope is even simpler, just use vines.
Yang Cheng assigned work and asked Yanhu and the others to chop down trees with thick copper knives. The speed was so fast that a big tree fell down in two or three strokes.
After the big tree fell, Yanhu and the others were asked to continue chopping it with their heavy swords.
Although the thick sword is made of brass, without the addition of pig iron or carbon, it should be very fragile. However, because Yang Cheng added enough materials and was beaten with strange force by the totem warriors, the blade of the thick sword is very strong.
But the blade is very easy to curl.
After all, the shape is that of a broadsword, not an axe, even an axe's blade will curl.
No, after cutting down trees for a while, Yanhu and the others found that the blade of the thick sword was curled up and was not as sharp as before.
Every one of them was heartbroken to death.
These eldest men were stabbed into their bodies with spears by the enemy, and even broke their bones after being hit by ferocious beasts during hunting, yet they could not cry out in pain. But when they saw their beloved weapons being damaged on the felled tree, everyone was so distressed that they were almost in tears, and a few guys had tears welling up in their eyes.
That would make Yang Cheng look more awkward.
The other totem warriors were shocked at first by how easy it was for Yanhu and the others to chop down trees with the weapons in their hands. A large tree held by two or three people could be chopped down in just a few strokes.
His eyes were always on the thick swords in their hands, filled with envy.
After seeing these thick and heavy knives cutting down trees again, I noticed the curling of the blades. Immediately, I couldn't help but take it in. I felt like my beloved weapon was damaged. I wanted to snatch the weapons from Yanhu and the others and use them. caress.
Some people feel sad and feel that such a good weapon is damaged by cutting down trees. What a pity!
But after hearing the end, Yang Cheng couldn't stand it anymore and told them that it didn't matter if the knife was sharpened. Just go back and find a gravel stone to sharpen it.
Yanhu and the others, as well as the totem warriors from other tribes, beamed with joy and cheered as if they had won a battle.
Yang Cheng shook his head, but he understood.
To primitive people like Yanhu, these swords were like a child getting a beloved toy, and any damage would be very sad.
However, there will be a day when toys get tired of playing with them. When there are more toys, children will naturally put aside the original weapons and play with new weapons.
This is the situation of the Qingque tribe now. There are still very few weapons. They are waiting for the number of copper weapons to increase in the future. Now everyone is sad about the slightest damage to the thick and heavy swords, but they will not care at all later.
Yan Hu is cutting down trees here, and the totem warriors from other tribes over there are not idle either.
After they watched the trees being chopped down for a while, Yang Cheng sent them off to look for vines.
Finding vines is not difficult. In the tribe, it is all done by the female tribesmen. Even if they do not have the power of totem, it is still extremely simple to find some vines in the woods.
Soon, two materials for making ladders, wood and vines, were available.
There was no need for Yang Cheng to guide the next work. Totem warriors who had experience building houses before quickly built simple ladders about two meters long.
Different from the ladders used when building houses, due to time constraints, Yang Cheng did not make a mortise and tenon structure for each ladder.
That's time-consuming, laborious, and cumbersome.
Yang Cheng directly asked them to use vines to tie the short pieces of wood to the long pieces of wood on both sides as the main poles. This might not be very strong, and the ladder might be deformed if stepped on twice.
However, Yang Cheng had no intention of stepping on it a few more times.
It only needs to be used once. Just let a totem warrior climb up the mountain wall, then tie the vines to a fixed object, and then hang the vines from the top.
With support points, all the totem warriors are good climbers!
