Han Cheng looked at the pile of bricks that collapsed and sniffed, then put the bricks aside and continued the work that seemed to never be completed.
There are not many shortcuts to the skills at hand. The only way is to improve your proficiency bit by bit through constant trial and practice.
He is just an ordinary person from later generations, without any superpowers, so he can only try again and again, learn lessons from the attempts, and then continue to try.
"Crash..."
Looking at the vaults that were finally connected together, before Han Cheng could feel happy, the bricks that had been pieced together collapsed again.
"Brother Cheng, get some mud on it and it won't collapse..."
Bai Xuemei, who stood watching for a while, finally couldn't help but speak.
She didn't understand why Brother Cheng only used bricks instead of using some mixed mud as an adhesive like he did before when building the wall, or simply using stronger cement.
How could it be built with only bricks and it was still in the air?
Why can't it be built up?
Bai Xuemei and the others have never been exposed to these things and don't understand the truth behind it. He has seen a skilled master craftsman before, how to use bricks to make an arch.
If you don't need anything to glue it together, it won't be strong enough.
There seems to be some kind of force involved. As a liberal arts student, he doesn't quite understand this, but he also understands that the principle is similar to that of an eggshell.
Most people cannot break eggs with thin and fragile shells by hand.
The vault that Han Cheng wanted to create was similar to this.
There is no need to be lazy here, and the vault is made of plant ash cement or mud. Its internal structure is not in a perfect state. Such a vault has insufficient load-bearing capacity.
Moreover, what Han Cheng is planning to build now is a brick kiln, and it is the kind of kiln that requires people to enter and put bricks in and take out the bricks.
How can we do this without taking it seriously?
Otherwise, if people are working in the kiln, and then the brick kiln collapses, then...
Han Cheng wiped the sweat from his forehead, stood up straight and took a rest. He smiled and said to Bai Xuemei: "You can't use mud on this one for the time being. I'll use mud after I finish building them... Didn't I already build them for a while?"
……"
Bai Xuemei blinked her eyes and collapsed as soon as she let go. Is that also called a base?
However, she didn't say any more. Since Brother Cheng said this, he must have a reason and he must be able to build these up without mud.
After standing here and watching for a while, she left and went to pick mulberry leaves with several other people in the tribe.
The silkworms have begun to shed their skins. After they shed their skins, they will eat a lot of mulberry leaves.
Han Cheng also continued his work of constantly building up and collapsing.
During this period, people came over more than once and offered him solutions like Bai Xuemei did, but they were all rejected by him with a smile.
The Zhaozhou Bridge can be successfully built with such a long span and has stood for thousands of years without falling down. Now I am building an arch with a span of only one meter. It makes no sense and cannot be done well...
Is the arch made without mud glue really stronger than the one made with mud?
After learning what the Son of God wanted to do, everyone in the Qingque Tribe was at a loss as to what they wanted to do. At the same time, they were looking forward to seeing what the Son of God had said to open their eyes.
The leader of the Donkey tribe, who is addicted to business, came again with the goods exchanged by the tribe. He couldn't understand these things that appeared outside the Qingque tribe.
The people of this tribe don't even see how they go hunting. They just scratch in the soil all day long and don't do their job... The key is that this kind of tribe is getting better and better, which is really uncomfortable.
Especially the Son of God, who kept using regular stones to build things, and they kept collapsing. In the time he saw it, it had collapsed four times.
This...is this really the son of God who is worshiped as a god by this powerful tribe?
The leader of the donkey tribe took the exchanged things and left, complaining all the way.
It was not without reason that he complained. Originally, he only needed to exchange the furs for pottery and other things. Now that the salt is not free, the same furs have to be exchanged for a lot less things.
Are you going to trade with other tribes again? Do you have to ask for more things in terms of salt?
The leader of the Donkey Tribe was thinking this way...
Not long after the leader of the Donkey Tribe left, Han Cheng finally finished the real vault.
The vaults, all made of dry bricks, did not collapse like before this time, but stood there quietly with curvature.
It's like being stuck with cement.
Everyone in the Qingque tribe who saw this scene looked very surprised when they saw this completely unreasonable thing.
What surprised them was what happened later. After waiting for a while, Shenzi put one foot on it.
This made everyone very worried. It is already very difficult to hold something like this up without collapsing. Why do you still have to step on it with your feet?
However, the expected sudden collapse did not occur. After the Son of God placed his feet on it, the thing that seemed to be unable to bear much weight and could collapse at any time turned out to be stable.
"Brother Cheng!"
After discovering that Han Cheng had the intention to go all the way up to the vault, Bai Xuemei shouted worriedly.
Although the vault is not high, it will not fall if you fall from it, but it is made of bricks, and it is very likely that your feet will be squeezed by the collapsed vault.
Han Cheng smiled at her and stood up.
Contrary to everyone's expectations, this seemingly unsturdy vault made of dry bricks with an elevated space in the middle actually withstood the weight of the Son of God without showing any sign of collapse.
Everyone looked at this magical scene and couldn't help but secretly marveled.
Han Cheng stood on it for a while and walked tentatively for a while. After discovering that the vault was very strong, he began to tentatively jump up on it, then continued to increase his strength, and finally jumped down with all his strength.
There was no sign of collapse, and Han Cheng couldn't help but smile.
Hard work paid off, and I finally got this thing out!
Everyone was very curious that the top, which didn't look strong at all, could withstand so much force. After consulting Han Cheng's opinion, they began to go up one by one.
After personally experiencing the strength of this vault, everyone was even more surprised. After successfully losing weight, the second senior brother, who was still the heaviest in the tribe, climbed up and jumped back and forth several times. As for the strength of this vault,
Everyone has a new understanding.
Amid everyone's regretful looks, Han Cheng personally dismantled the vault that had been built with great difficulty.
Then one of the 'low walls', which was only thirty centimeters high, was also demolished. After moving it back half a meter, the vault continued to be built with bricks.
Only this time the span of the vault reached one and a half meters.
"Crash..."
As Han Cheng expected, the first attempt failed again.
However, with his previous experience in building small vaults, this vault with a larger span did not fail too many times. By the next day, he had it set up.
