The polar peoples in the Arctic build their houses with ice and snow. However, Li Mengxi cannot remember whether they are made of ice or snow.

Li Mengxi chose to use snow to cover the house, because ice cubes are difficult to cut and stack.

When building the snow house, Li Mengxi chose two structures. One was the skeleton structure. That is, he first found many branches and woven them into a greenhouse-like arched structure on the ground, and then poured the snow above.

The second structure is to pile the snow from all over the place together to build a huge snowdrift, then beat the snowdrift solidly, and then slowly dig out a room from it.

The construction of the two structures started at the same time. When the branch roof was erected, the snowdrifts were also piled up.

The two groups, one on the left and one on the right, were working enthusiastically. One group started shoveling snow and throwing it on the roof of the tree branch shed, while the other group began to dig in from the middle of the snowdrift. Li Mengxi watched with interest. He must have used tree branches.

The structure must be stronger, Li Mengxi thought.

Half an hour later, one igloo was piled up and the other igloo collapsed.

Maybe the snow pile was not solid enough. When the craftsmen dug holes in the snow, the snow kept collapsing, making it impossible to continue.

Sure enough, the igloo still had a strong skeleton. The igloo looked like half an egg on the ground. Li Mengxi thought it looked like a mushroom, but Liu Bei said it looked like a grave mound.

Li Mengxi couldn't help but roll his eyes at Liu Bei.

The snow house was finally built, and Li Mengxi couldn't wait to get in and take a look.

Arriving at the snow house, Li Mengxi looked around curiously. Above his head, the roof made of branches was slightly bent by the weight of snow, but it was still strong.

Li Mengxi couldn't help but admire that the dome structure is really good. Some branches that are no thicker than a finger can be braided into an arch shape and can withstand hundreds of kilograms or thousands of kilograms of snow.

Can a house made of snow really be warm? Li Mengxi stood in the snow house and felt it carefully for a while. Well... he didn't feel it.

Then he got out again. As soon as he got out of the igloo, he immediately felt the cold wind. The wind was blowing in waves, and it was very cold.

After standing outside for a while and carefully feeling the temperature outside, Li Mengxi immediately got back into the igloo.

The feeling is very obvious. As soon as I enter the igloo, the wind disappears and I feel much warmer.

Li Mengxi tried again many times. He kept getting in and out of the snow house, very active, like a mouse.

Liu Bei and Guan Yu couldn't help but smile.

When Li Mengxi came out of the igloo and stopped going in, Liu Bei and Guan Yu approached him.

Li Mengxi thought that he and Guan Yu also wanted to go in and have a look, but Liu Bei and Guan Yu walked to the snow house, bent down and stretched their necks to look inside, and refused to go in.

"Would you like to go in and take a look? What can you see outside?" Li Mengxi invited enthusiastically.

Liu Bei and Guan Yu were unmoved and refused to go in at all.

After finishing reading, Liu Bei stood up and looked at the entrance of the snow house, which was as big as a dog cave, and then looked at Li Mengxi who was standing aside with a red face and said, "Xi'er, why don't you dig a bigger door? It's so small.

It's like a dog hole."

Li Mengxi laughed immediately, "A dog hole is better! Haha!" He laughed happily, "If the hole is big, it can let in wind and air-conditioning, but a smaller hole will keep you warm."

Li Mengxi said that the igloo was very magical. However, after it was built, it was as small as a small pile as big as a tomb bag. The door was as small as a dog hole. The more it looked, the more shabby it became. How much do you look forward to it? Liu Bei and Guan Yu

How disappointed the two of them are now.

Liu Bei asked again uncertainly, "Can this snow house really sleep people? Will people not freeze to death?"

"Yes!" Li Mengxi nodded firmly, "It will definitely be warmer than outside anyway. However," Li Mengxi looked back at the igloo, let's give it a try."

The igloo is indeed very good at blocking the wind, and it is much warmer than outside, but it doesn't seem to be much warmer. It still seems to be sub-zero temperature inside.

This made Li Mengxi not sure whether something would happen if he stayed overnight in the snow house.

Li Mengxi decided to try it himself. He asked people to bring bedding, climbed in and made the bed, ready to move in.

After lying down for a while, Liu Bei called Li Mengxi out.

After asking clearly what Li Mengxi wanted to do, Liu Bei was silent for a moment, "Isn't it right for you to find someone? Why try it yourself?"

What should Liu Bei do if he is afraid that Li Mengxi will freeze to death again?

Li Mengxi thought about it, what if it was very cold in the igloo and he froze to death inside.

After a second thought, Li Mengxi decided not to try it himself, but to find a warrior to try it.

After a while, Li Mengxi found a soldier who was willing to take the risk himself.

Li Mengxi is very grateful to those who came forward.

He explained carefully, "Don't forget that this house is made of snow. It's much warmer inside than in a tent."

Although Li Mengxi said this, the soldiers did not believe it. He came with the idea of ​​​​a narrow escape from death.

"Go ahead. It's been cleaned inside. There are two layers of mats and quilts."

"Go in and lie down. Remember, don't fall asleep. Don't fall asleep."

Li Mengxi was afraid that people would freeze to death unknowingly. If they were awake, conscious, and came out when they felt cold, they would definitely not freeze to death.

Li Mengxi's repeated explanations made the careless and bearded soldier very confused.

Since you were told to sleep inside, why didn't you let me fall asleep instead of just lying there and staring?

The soldier scratched his head and lowered his body to get in.

"Slow down!" Li Mengxi stopped, "Drink a bowl of hot water before you go in." He came with a bowl of hot water.

The soldier obeyed his order, drank a bowl of hot water, and then hugged his fists towards Li Mengxi. Then he turned around with a determined look on his face, stooped down and crawled into the low hole.

Li Mengxi was surprised as to why this man looked so determined to die.

Are igloos so scary? Are people so afraid of igloos?

If this is the case, it is still a bit difficult to promote igloos. It is estimated that if igloos are built and people live in them, the people think they are going to kill people, so they will sneak out and even destroy the igloos secretly.

After the soldier got in, he lay down on the bed and wrapped himself in a quilt. Li Mengxi poked his head outside and asked, "How is it? Is it okay inside? Is there no wind at all?"

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The soldier raised his head, grinned, "It's not bad."

"That's good." Li Mengxi also smiled at the soldier.

Finally, Li Mengxi thought about it, ran away, found a thin wooden board, blocked the entrance of the igloo, and covered the surrounding area with snow before opening an opening.

In this way, there is only one gap in the entire igloo for air to enter and exit, and the thermal insulation effect is once again enhanced.

Li Mengxi shouted inside, "I sealed the hole, leaving a gap. If you feel bored, remove the board yourself."

A voice of agreement came from the snow house. After finishing all this, Li Mengxi went to do other things.

On this day, the whole day's busy focus was entirely on infrastructure.

By the afternoon, towards evening, the permafrost walls around the camp had been built.

Although the walls are uneven due to the different lengths of each cart body, the lowest point is still a head higher than a person.

Everyone went to inspect the camp together. The earthen walls of Nuo Da's camp completely surrounded the camp.

If you just use the broken wall made of soil, forget it, it's not that amazing.

Frozen soil walls can be frozen. Frozen soil has similar properties to quick-drying cement. The soil is pounded and filled into the mold, and then hot water is poured on it. It will soon freeze hard again due to the cold, and the final earth wall will be used.

It's the same as when it comes out of the mold, very flat, smooth, with sharp edges and corners.

In a word, it looks very good, and is much more regular than the earthen walls of shabby private houses. It is almost like a city wall.

Both Liu Bei and Guan Yu were extremely satisfied with the frozen soil city wall. Unexpectedly, they actually built the city wall in just one day. The speed was amazing.

"It's a little low," Liu Bei looked at the flat earth wall and said, "It would be better to be higher."

"But the mold is only so high. It's easier to build a building that's as tall as a person, but it's not even remotely difficult." Li Mengxi retorted from the side.

In general, building height is exponentially related to construction difficulty.

Building a building with two people tall is not twice as difficult as building with one person tall, but ten times more difficult.

A wall as high as one person does not require any auxiliary tools. A person can stand on the ground and stretch out his hands to add soil little by little, and a high earth wall can be built directly.

But if you build a wall that is two people high, you have to use a ladder, and you have to add a feeder who is responsible for delivering the bucket of mud to the person on the ladder.

When it reaches the height of five people, it is no longer possible to rely on people to feed materials, and people cannot lift it that high. At this time, slides and booms have to be used.

When the height reaches ten people, even the ladder is no longer long enough. Scaffolding must be built and a complete set of tools must be provided.

The same goes for building permafrost walls.

Although the permafrost wall is very simple and can be built in one day to a height of one person, but if you want to raise the wall from one person to two people, it will not take one day of work, nor two days of work.

Even four days is not enough, eight days may be enough.

After the height exceeds one person's height, the mold must continue to be moved upwards. But there are no lightweight molds in the military now. The mold is just a pallet truck. It is difficult to move the heavy pallet truck to a place as high as one person and fix it.

Not small.

The city was ten feet high, and the number of workers increased tenfold.

On the way back, everyone had different opinions and each expressed his own opinion.

Liu Bei still wanted to build the wall higher. Liu Bei's reason was that although the wall was raised, it was not as high as the top of the tent. Although it could block the wind, it could not block the wind well.

There is no need to add much height, just add three feet, and the wind blocking effect will be much better.

As for the issue of working hours mentioned by Li Mengxi, Liu Bei said that anyway, if you have nothing to do in winter, you will be idle if you are idle. It is not good to be warm if you are busy.
