It was a building that looked like a "yurt".

It is supported by a thick trunk on all sides, and small branches are densely packed in the middle, spreading inch by inch upward, and finally paved with layers of leaves

- This building looks very simple, but it took dozens of them to build it for two days!

- After all, there are many people, so make sure that the place is large enough.

But the seemingly sturdy building suddenly collapsed when it was finally topped out.

Although no one was injured, it can bring more than a half-star blow to everyone.

At this time, to build a house, they paid a lot.

The weather was too cold, the stone pot was too slow to boil water, and everything they came into contact with every day was basically cold.

Even if Zhou Shuangshuang cheated and generally brought all kinds of cotton gloves, knitted gloves, and the kind of fleece plastic gloves used for washing dishes......

However, people who are reluctant to wear new clothes, even if they learn to wrap themselves in layers of leaves, will still inevitably suffer frostbite, smashes, and scratches from branches......

For them, enduring hardships and injuries is a common thing, but in Zhou Shuangshuang's eyes, they still can't help but feel distressed and guilty.

- After being together for so long, even if they haven't fully evolved well, even if they still retain the characteristics of animals, even if they have ugly faces, even if they ...... They are uncivilized.

However, this is people.

It's exactly like the original ancestors of humans on Earth.

What the first humans on Earth did to survive, they have also done......

Zhou Shuangshuang and them are all the same.

…………………………

After the house collapsed, she was even about to give up.

There's a cave anyway, isn't there?

This is a relatively gentle slope on the mountain, and the only places suitable for digging caves have been excavated several caves.

Anyway...... Anyway, they used to spend the winter in caves, and it was risky to build a house, so why bother them to bother with it?

Zhou Shuangshuang had a moment, and the thought of retreating was extremely strong.

But in the next moment, she let out a big sneeze.

- It's too cold.

Her physical fitness is already extraordinary, and even she can't stand it wrapped in a down jacket, so can these people who only have leaves wrapped around their bodies really want to shrink in that watery cave and carry it through the whole winter?

That cave is full of mud when you step on it! Even if you light the fire, the whole hole won't be dry!

She turned back and looked at the information again.

- The mechanical limbs of the cross-era have been gnawed off by her, Zhou Shuangshuang still doesn't believe it, a method of building a house 10,000 years ago, can she still learn it?!

……………………………

Knowledge changes destiny, and knowledge changes the world...... That's true.

Zhou Shuangshuang seriously studied the information.

In fact, this method of building a house is not too complicated, and even the most basic calculations and measurements do not have to be done. It's just that Zhou Shuangshuang was too anxious at first, so she read it twice hastily, and directly arranged for everyone to work.

This time, she simply calmed down and took everyone to learn together.

On that information, all the knowledge about primitive architecture is there, and there are intimate pictures. Zhou Shuangshuang led everyone, even if the verbal communication was not 100% harmonious, the thick stack of drawings that were enlarged by her in the later stage was enough for everyone to slowly understand.

- It doesn't matter if she learns to build a house or not, she has a house anyway.

But primitive people must be learned.

Otherwise, the Xiaoice River period would not have been able to survive at all.

………………………

They began to lay the groundwork.

There are also many ways to lay the foundation, and Zhou Shuangshuang couldn't decide which one was the most solid, so he decided to choose two ways to do both.

- First they dragged the trunks of trees they thought were the strongest and thickest from the forest, and nailed them into the ground.

Then, the entire piece of land used as the foundation was guided by Zhou Shuangshuang, and the simple stone mill they made was rolled several times......

In the end, relying entirely on manpower, the land was tamped with a hammer little by little.

In the end, even if Zhou Shuangshuang broke the trunk of the tree that had penetrated into the ground, it was difficult to shake it, and it was finally over.

Don't look at it as just a small foundation work, but this program alone, dozens of people worked in shifts for two days.

They can endure hardships without fear of tiredness, have great strength, and have good physical fitness—even if they built that house before, it only took two days.

It can be seen that such a foundation is unique.

- The foundation laid in this way is not solid, and to be honest, Zhou Shuangshuang has no bottom.

But if it doesn't work, you have to try. Even if it doesn't work out this time, next time, next time, this winter, next winter...... There will always be a time for success.

As long as it succeeds, there will always be people who will survive because of it.

…………………

The foundation was laid.

They were not afraid to exert themselves, and used as many thick trunks as possible, calculated the safest distance, and formed a large circle.

In the middle of the trunk of the tree, and then use a slightly shorter trunk to cross up and down to fix it - this Zhou Shuangshuang provides iron nails in order to stabilize it - after all, in order to meet the possible snowstorm, she really wants to buy a suite directly and bring it over......

Then, on top of the cylindrical structure, a tree trunk was stuck to the intersection at the top, enclosing a yurt-like vault......

When all the frames were made, Zhou Shuangshuang held the trunk and shook it vigorously, and finally couldn't help but burst into tears......

Really...... It's not easy!

She was so excited that she almost cried - I just don't know, with this skill, will she have the opportunity to enter real estate in the future?

Even if you don't want to be a developer, you can do earthwork on the construction site......

………………………

This huge house is almost finished.

Everyone happily found the leaves that met the requirements, regardless of what was unified or not, and hurriedly tied the bark layer by layer and stacked it on the trunk.

Zhou Shuangshuang looked at it, and was afraid that the leaves would be too scattered to withstand the strong wind, so after the leaves were covered with a layer, she worked with everyone to weave a big fishing net-like cover and cover the leaves.

Then, a second layer of foliage began.

- Of course, there is definitely more to the fishing nets.

And the other one became Qi's first fishing tool.

——When the house was finally built, Zhou Shuangshuang opened the door woven with leaves, and solemnly asked everyone present to be surprised and sighed, obviously they built the house by themselves, but the unbelievable people entered the house together.

The room was large, empty, and dim.

However, even if there is no fire, it is very warm.

It's warmer than their damp caves.

The tightly blocked "yurt" is airtight except for the open doorway, which can still reveal some light.

Zhou Shuangshuang poked the roof with a stick.

There, a wall of leaves slid down.

Since the "yurt" is imitated, then the ventilation hole on the top of the felt should naturally also be there.

Otherwise, when they burn the fire, how can they breathe and exhaust the smoke?
