Wilderness: After the college entrance examination, I got the strongest survival system

In fact, Li Yingjie thought that sealing the roof with mud and leaves could already prevent rainwater.

Unless it is a torrential rain, it is impossible to completely wash away their roof.

Because of this, he has not been too worried about the roof breaking.

The last time it rained heavily, it only washed out one layer of the roof in the end.

But now, they have no survival crisis for the time being, and they can completely think about how to make the cabin better.

As long as one person stays here in the future to ensure that the cabin is not damaged, then it is still very valuable to improve the cabin.

Therefore, even if it is difficult to burn tiles, Li Yingjie is going to make a batch.

Lin Xiaoying looked at the clay in her hand, then at Li Yingjie.

She doesn't know much about tiles, because she grew up in the city since she was a child, and she hasn't seen tiled houses a few times.

"What is the tile going to do? How does it keep out the rain?"

In the bottom of her heart, Lin Xiaoying only had a general idea, and felt that the tiles were superimposed one by one, so that rainwater could flow down from above without leaking into the house.

However, she really didn't know exactly what it looked like.

So, she asked Li Yingjie curiously.

Li Yingjie smiled.

He grabbed a piece of clay, flattened it, and kneaded it into a ten-centimeter-long curved tile-shaped piece of clay.

Then, he grabbed another piece of clay and kneaded it into an arc-shaped piece of clay again.

He put these two arc-shaped mud pieces, one above the other below, overlapping each other by about two centimeters, and placed them on the ground.

Li Yingjie pointed to them and said to Lin Xiaoying:

"You see, when the rain falls, it flows down from the top. These tiles are superimposed one by one, and the rainwater will flow from the previous tile to the next tile, and then flow to the next tile. On the piece, until the end, falling from the eaves."

Lin Xiaoying suddenly realized.

In an instant, she understood why the roofs of those tile-roofed houses were slanted, in order to allow the tiles to be stacked one by one to protect the entire roof.

This is actually a very simple principle. Lin Xiaoying just didn't understand it before, so after hearing it, she immediately understood it.

In their live broadcast room, some people understood it immediately, and some people were still wondering.

Bravely signed: "What does the top flow to the bottom, what does that mean?"

Not afraid of difficulties: "That is to say, the water flows downhill, so the rainwater on the tiles above will flow down, and then flow down layer by layer, and then fall from the eaves."

Bravely signed: "What does this have to do with rain?"

Not afraid of difficulties: "Tiles are used to prevent rain. People use tiles to build houses..."

Bravely signed: "Why is it involved in building a house again?"

Not afraid of difficulties: "What they are talking about is building a house!"

Bravely signed: "Didn't they say that clay is waterproof?"

The old teacher, my classmate He, said: "This question is too profound. I suggest you ask it after finishing the first grade of elementary school! Also, 'Don't be afraid of difficulties', you are really not afraid of difficulties. You can explain so much to him!"

……

In the wilderness, Lin Xiaoying also grabbed a piece of clay and shaped it into a tile.

These are actually very simple tiles, which are made into an arc by kneading mud.

Lin Xiaoying asked: "Should we make these now? It looks easier than making brick embryos!"

Li Yingjie shook his head.

"Pinching by hand is definitely not enough. If the tiles are uneven in size, it will affect the use."

When making bricks, they don't need to have a specific size of the bricks, anyway, they need to be fixed with mud in the middle.

So, just squeeze it with your hands.

It is convenient and fast.

But unlike bricks, these tiles must be the same size in order to fit together perfectly.

Otherwise, it will not be able to protect against rain and water.

Lin Xiaoying thought for a while, and immediately said with a smile: "I understand, let's make a mold now, and then we can make these tiles the same size!"

Li Yingjie nodded and praised: "That's right, the response was quick. We'll make a mold today, and use the remaining clay to make bricks. Tomorrow, we'll burn the mold and start making tiles."

With that said, Li Yingjie grabbed a large piece of clay and began to make tile-shaped molds.

All the tiles not only need to be the same size, but also should be suitable for fit, that is, two tiles should fit together exactly.

Therefore, Li Yingjie was very serious when making the mold.

It was not until evening that the mold was made.

Lin Xiaoying looked at it carefully and asked how to use it. Li Yingjie pointed to the groove and explained:
"After these two parts are put together, there is exactly a tile-shaped groove inside. When using it, you only need to stuff the clay into it, and then press the mold tightly, and the clay inside will become the shape of the tile."

Only now, the mold is still wet clay, and it must be dried before being fired into pottery before it can be used.

Therefore, Li Yingjie had no way to try.

He put the mold in a dry place to dry, and then continued to make bricks with Lin Xiaoying.

"After the mold is burned tomorrow, we need to take a rest." Li Yingjie said.

Although the tiles have not yet started, Li Yingjie has already begun to imagine how to build them on the house.

At that time, my small wooden house will also have a tiled roof, no matter how much rain falls, the inside of the house will not be wet.

Just think about it and feel safe.

Lin Xiaoying also showed similar expectations on her face.

The two speeded up and made the remaining clay into bricks. Then, they cut some bear meat, found some wild vegetables nearby, and cooked a pot of broth.

It's a pity that the weather is too hot, and drinking broth is somewhat unhappy.

However, after eating and taking a bath, they still feel very satisfied.

"Today has been No.20 for four days, and I don't know what happened to everyone else!"

Li Yingjie sighed.

Thinking that someone had already started to observe other people's shelters and was about to destroy them, he suddenly felt that the result of the competition was about to come to an end.

However, I'm not sure, if there are a few people who hide relatively quietly and compete with each other non-stop, maybe this competition can last for a long time.

They went back to the cabin and closed the surrounding doors.

Outside the cabin, Li Yingjie put a lot of dry twigs on the ground.

If someone gets close, it is easy to step on the branch and break it, and it will make a noise at that time.

This can be regarded as a mechanism set up by Li Yingjie around. If he is not particularly tired, he will not sleep so hard, and the sound will definitely be heard clearly by then.
