I am a Primitive Man

Han Cheng looked at the collapsed pile of bricks, sniffled, then put the bricks aside and continued with this seemingly impossible job.

There are not many shortcuts for the skills in hand, and the proficiency can only be improved little by little through continuous trial and practice.

He is also just an ordinary descendant, without any superpowers, so he has to try again and again, and learn lessons from the attempts, and then continue to try.

Clatter...

Looking at the vaults that were finally joined together, Han Cheng hadn't had time to be happy, the bricks that had been pieced together collapsed again.

Brother Cheng, get some mud and it won't collapse...

Bai Xuemei, who stood by and watched for a while, finally couldn't help but speak.

She didn't understand why Brother Cheng only used bricks instead of using some reconciled mud as the adhesive, or simply using stronger cement as he did when building the wall before.

In this way, only bricks are used for the base, and it is still empty. How can it be possible to build it?

How could it not be built up!

Bai Xuemei and the others had never been in contact with these people, so they didn't understand the reason behind it. He had seen a good craftsman before, how to use bricks to make an arch.

If you don't need a little something to glue it together, it won't be strong.

There seems to be some kind of power involved here. As a liberal arts student, he doesn't know much about it, but he also understands that the principle is similar to that of an eggshell.

Eggs with thin and brittle shells, if you want to break them with your hands, most people can't do it.

The vault that Han Cheng wants to make is similar to this.

There is no need to be lazy on this, and the vault that was forced to use plant ash cement or mud to condense, its internal structure has not reached a perfect state, such a vault, the load-bearing capacity is not enough.

Moreover, what Han Cheng is going to build now is a brick kiln, and it is the kind of kiln that requires people to enter the inside to put bricks in, and the bricks to go out.

How can you not take it seriously?

Otherwise, people are working in the kiln, and then the brick kiln collapses, then...

Han Cheng wiped the sweat from his forehead,

Standing up straight and taking a rest, he smiled and said to Bai Xuemei: I can't use mud for this right now, I'll use mud after I've built them up... didn't you just build them up for a while...

Bai Xuemei blinked her eyes, she collapsed as soon as she let go, is it also called Lei Hao?

But she didn't say any more. Since brother Cheng said that, he must have his reasons, and he must be able to build these without mud.

After standing here and looking at it for a while, she left here and went to pick mulberry leaves with several other people in the tribe.

The silkworms have started to shed their skins, and after they have shed their skins, they will eat a lot of mulberry leaves.

Han Cheng also continued to keep building up and collapsing.

During this period, someone came over more than once, offering him a solution like Bai Xuemei did, but he rejected them all with a smile.

The Zhaozhou Bridge can be successfully built with such a long span and it can stand for a thousand years without falling down. Now I have built an arch with a span of only one meter. It doesn’t make sense to fix it...

Is the arch made without mud bonding really stronger than the used one?

Everyone in the Qingque tribe who learned what Shenzi wanted to do was puzzled, and at the same time, they were looking forward to what Shenzi said, so that they could open their eyes.

The leader of the donkey tribe, who is addicted to business, came again with the goods exchanged by the tribe. He expressed his incomprehension about these things that appeared outside the Qingque tribe.

The people of this tribe, I don’t see how they go hunting, they just scratch in the soil all day long, and they don’t do their jobs... The key is that such a tribe can get better and better, which is really uncomfortable.

Especially that Son of God, who kept building things with neat stones, and kept collapsing. When he saw it, he had collapsed four times.

This...is this really the Son of God who was 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's not without reason that he complained. Originally, he only needed to exchange the fur he bought for pottery. Now that the salt is not free, the same fur needs to be exchanged for a lot of things.

Do you want to make deals with other tribes again? In terms of salt, do you want more things yourself?

The leader of the donkey tribe was thinking like this...

Not long after the leader of the donkey tribe left, Han Cheng finally finished the real vault.

The vault, which was all built with dry bricks, did not collapse like before this time, but stood there quietly with an arc.

It's like being stuck in cement.

Everyone in the Qingque tribe, who saw this scene, looked very surprised at this completely unreasonable thing.

What surprised them was the back, and after waiting like this for a while, Miko put one foot on it.

This made everyone very worried. It is already very difficult to support such a thing without collapsing. Why do you still use your feet to step on it?

However, the expected collapse did not occur. After Shenzi's feet were placed on it, the thing that seemed unable to bear much weight and was about to collapse at any time turned out to be stable.

Brother Cheng!

After discovering that Han Cheng had the whole intention of going up to the vault, Bai Xuemei cried out worriedly.

Although the vault is not high, it cannot fall if it falls from above, but it is built with bricks, and it is very likely that the vault will squeeze your feet after it collapses.

Han Cheng smiled at her and stood up.

Contrary to everyone's expectations, this seemingly weak, dry brick vault with a hollow in the middle has actually withstood the weight of the Son of God, and there is no sign of collapse at all.

Everyone looked at this miraculous scene and couldn't help but secretly amazed.

Han Cheng stood on it for a while, walked tentatively for a while, and found that the vault was very strong. He began to tentatively jump up on it, and then continued to increase his strength. Finally, he jumped down with all his strength. There was no sign of collapse, and Han Cheng couldn't help smiling.

The hard work paid off, and I finally managed to get this thing out!

Everyone was very curious about how the seemingly weak top could withstand so much force. After consulting Han Cheng's opinion, they also started to go up one by one.

After personally experiencing the firmness of the vault, everyone was even more surprised. After the weight loss was successful, the second senior brother who was still the heaviest in the tribe went up and jumped back and forth several times. Everyone has a new understanding.

Under the regretful expressions of everyone, Han Cheng personally dismantled the vault that had been built with great difficulty.

Then one of the 'low walls', which was only 30 centimeters high, was also demolished. After moving it back half a meter, it continued to use bricks to build the vault.

Only this time the span of the vault reached one and a half meters.

Clatter...

As expected by Han Cheng, the first attempt failed again.

However, with the experience of building a small vault before, this vault with a larger span did not fail too many times. On the second day, he set it up.
