Soon, everyone who was still knocking stopped their movements, and then looked at Yang Cheng with blank faces, wondering why Yang Cheng suddenly made them stop their movements.
Yang Cheng did not explain.
He touched his chin and looked at the big rocks.
There are not many broken stones among these exposed big stones, they are all big stones connected to the mountain.
Unless a large machine is used, it will be very difficult to break these stones out with the strength of the current totem warriors.
How to do it?
Yang Cheng touched his chin, squinted his eyes, and tried to remember how the ancients cut mountains and extracted rocks before gunpowder appeared on the earth.
tool?
Use an iron tool to smash the stone vigorously, and break the stone to get chunks?
However, except for the copper ore obtained from the Stone Tribe, Yang Cheng did not find any other copper ore ore in the surrounding area.
Is it possible to go out again and get all the copper ore from the Stone Tribe?
However, winter was about to come, and Yanying didn't come over. It would take a long time to go out to the Stone Tribe, and she might encounter some ferocious beasts.
Yang Cheng didn't want to encounter things like the divine fruit tree again, which would cost his life. It would be great and enjoyable to stay in the tribe.
While Yang Cheng was thinking.
A gust of cool wind blew on Yang Cheng's body, slipping through his exposed animal skin clothes, making him couldn't help but tighten his body.
Fortunately, this cool breeze is just a gust.
When the cool breeze dissipated, his body couldn't help but relax.
"Hey, wait."
The natural changes in the body made Yang Cheng think of something!
"Yes, thermal expansion and contraction!"
Yang Cheng's eyes lit up and he fisted with his palms.
This is the simplest common sense of physics. According to the words in "Wulin Gaiden", this is common sense of physics that even Xiaobei knows.
Just because it's too simple.
Yang Cheng didn't think of it for a while.
Now that you remember this common sense of physics, the rest will be easy.
Yang Chengdao: "Yanhu, take your people to find some wood. You want smaller ones, not too big ones. It's best to just ask for branches from those trees."
Yang Cheng specially told this, because he was afraid that Yanhu and the others would just cut down a few trees to save trouble. Such wood can burn a big fire, but it will be particularly big when used to bake stones.
"Yes, Wu."
Yanhu ordered a few people and went to find wood.
After he left, Yang Cheng turned around again and said to Cang Shi: "Cang Shi, take some exiles to the river we just met, cut some bamboo, make bamboo barrels, and then use the bamboo barrels to Scoop water from the river, and the more water you can scoop out, the better.”
When Yang Cheng brought them over just now, he discovered another small river. The river was seven or eight meters wide and three or four meters deep.
There are also various fish-shaped beasts in the river.
However, after eating the double-bearded fish for so many days, everyone no longer felt the surprise of eating the double-bearded fish in the first place.
Now the fish-shaped ferocious beasts and other ferocious beasts have the same feeling towards the people of the Qingque tribe.
Before the emergence of new materials and methods, people no longer had any interest in eating them just to fill their stomachs.
Cangshi is more stable than Yanhu.
It is also an order for Yang Cheng to do without thinking, but he will think about it.
Judging from Wu's thinking actions while standing in front of these big rocks, Cangshi could tell that Wu was thinking about why he mined these rocks.
But after the witch finished thinking, instead of teaching everyone how to mine stones, he asked them to find wood and water.
This made Cangshi feel confused.
Do these two have anything to do with mining stone?
But thinking that the witch was omnipotent, he was overjoyed and took some exiles to get water.
The people left behind were not idle either. Yang Cheng asked them to dig up the soil under the big rock so that they could start a fire underneath.
Yanlin and Xing will be extremely bored now.
Although they followed Yang Cheng out, Yang Cheng wouldn't let them do this or that.
So, I can only play with the Niu Niu.
They fed the mud cows with withered grass and leaves, and then made the mud cows spit out the mud. Then they made clay figurines for the two of them and played with mud.
Xi Ni Niu had a grimace on his face, but knowing that Yan Lin and Xing were Yang Cheng's witches, he didn't dare to disobey.
At the end of the vomiting, all the mud was finished, and I could only fall to the ground tiredly, sticking out my tongue and gasping for air.
Yan Lin and Xing pouted and were unhappy, and complained to Yang Cheng: "Wu, you are not good at this bonded beast. How about we kill it and eat it?"
Yang Cheng hasn't spoken yet.
The mud cow immediately stood up, ate the grass next to it, and started spitting out the mud again.
Seeing this, Yan Lin and Xing cheered again and continued to liven up the mud.
Fortunately, Xini Niu didn't suffer much anymore this time.
Because Yanhu and Cangshi are back.
Yanhu led his men to find branches that were three or four meters high like a hill. They all followed Yang Cheng's instructions. There was no big tree.
In Cangshi, each person carries two bamboo tubes with a diameter of more than one meter, about thirty or so.
Yang Cheng was very satisfied with the results of Yanhu and Cangshi.
These firewood and cold water are enough to make a few rocks on the rocky mountain in front of them experience both the ice and fire.
"Yanhu, put these firewood under that rock."
Yang Cheng picked a rock, which was about the size of two mud cows.
Wait for Yanhu to put the firewood away.
If Yang Cheng makes people drill wood and start a fire again, there is nothing good to say. Not to mention the old people of the Qingque tribe, the new people also learn very quickly.
Now almost every clan member carries materials for drilling wood and making fire.
A totem warrior held the wood and turned it twice, and the flames ignited.
Under the command of Yang Cheng, the tribesman placed the lit firewood under the big rock.
Suddenly, the firewood pile under the big rock was also ignited, and the flames rolled. The flames at the top of the flames scattered when they encountered the rocks.
See this scene.
Everyone present did not understand why Yang Cheng did this.
Can stones be boiled using fire?
This shouldn't be the case!
In everyone's impression, stones cannot be boiled and will not be burned.
"The fire is not big enough, add more wood and keep burning!"
Yang Cheng looked at the fire and felt it was not enough, so he asked everyone to continue adding firewood inside.
After adding more firewood, the fire became even bigger, and the flames spread out in all directions. At the same time, everyone felt a strong wave of heat.
The heat forced everyone to move back several steps.
However, everyone was still puzzled.
Stone cannot be burned. No matter how powerful the flame is, it will not burn.
Look, under such a fire, the stone only became a little charred, but it still remained motionless.
"It's not enough, add more firewood!"
Yang Cheng didn't have so many doubts as everyone else. He felt the heat wave and continued to order everyone to add firewood.
