Forced by the current serious security problems, Chen Ducai proposed to build some fortifications, but in fact, it was only a vague concept, and there was no mature idea.

However, unexpectedly, Tang Jing had already made a plan.

Chen Du saw her squatting on the ground drawing something yesterday, and at that time she only thought it was boring graffiti, but now she looks at it, and these horizontal and vertical patterns are actually drawings marked with accurate data dimensions.

Of course, it may be an exaggeration to say that the drawings are made.

It's not rigorous enough yet.

But even from the perspective of an ordinary high school student like Chen Duan, he can roughly understand it.

"You started drawing this yesterday?"

"Well, as I said before, there are a few ideas, but you need to cooperate."

"These ...... Is it the size of the part? Chen Du pointed to one of the giant patterns marked with length and width.

"Yes."

"I don't really understand."

"I probably have two ideas, the first is to block the crack in the door, leaving a passage for people and flatbed trucks to enter and exit, close it in normal times, and open it when you need to enter and exit, and second, to build several houses directly in the room."

"House?"

The idea of blocking the crack in the door was understandable to Chen Duan, and he even thought about it himself.

But in the end, he gave up, the door of this storage room is about 1 meter wide, and the door crack is 1 cm high.

There is also an idea of using ready-made items such as chopsticks to block the cracks in the door, and with Wei Dalei's strength, it is not a problem to carry things.

But as it turned out, it didn't work either.

The stainless steel chopsticks are round, and the two ends are not the same size, if Chen Du is allowed to use his ability to transform its shape, it is also a big project, the problem is that after it is done, it is still impossible to fit it tightly.

But the idea of building a house has never been the same for Chen Duan.

Tang Jing said: "That's right, the option of blocking the door crack, in fact, I personally don't agree with it, this can indeed completely prevent rats, snakes, centipedes and other larger animals, but the disadvantages are also obvious, first of all, it takes a long time, and secondly, small reptiles like cockroaches and ants, even if there is no door crack, can still easily come in, then spend this kind of effort, it seems that the cost performance is very low." ”

"But can we build a house?"

"It's up to you." Tang Jing said with a smile.

"If I had the ability, I would have gotten myself a mansion a long time ago."

Chen Du is now able to control the limits of objects, even if he does not speed up and consume mental power, it is only equivalent to half the weight of his body, which is indeed much better than the first day, but it is still far from the point of "building a house".

Tang Jing smiled: "Of course it's unrealistic to rely on you alone, but we still have so many people." ”

"Huh?" Chen Du was puzzled.

"It may be difficult to change a house in one go, but we can break it down."

"Decomposition?"

"Yes, the house is nothing more than four walls and a ceiling, and then equipped with doors and windows, from the structure is very simple, you just need to make each part one by one step by step, and then build, isn't it much simpler?"

"Hmm......" Chen Duan hesitated.

"I ask you, if you were asked to make a plastic sheet that was more than one person tall and two people wide now, how long would it take?"

Chen Du thought for a moment and said, "This is bigger than the bottom of the flatbed, if you don't need other detailed requirements, it is estimated that it will take a few minutes." ”

"Congratulations, you've built a wall." Tang Jing gave a thumbs up: "What we need now is just a place to hide temporarily, and a safe space to sleep at night, and we are not really going to build a mansion, perhaps, it is a bit ambiguous to say that the house is a bit ambiguous, you can think of it as a container, or even ...... Coffin. ”

"This ...... Coffin? ”

"Yes, you can lie in the coffin of four or five people, sleep at night and get in, if there is danger, at least you don't have to worry about it every day, there is nowhere to hide." Tang Jing explained.

"I see what you mean."

"Of course, there are some details, such as ventilation, it's summer, and even if it's not too hot at night, it won't be good for a few people to be crammed into a confined space. Also, the house must be fixed to the ground, otherwise a big thing might eat us with the house. ”

I have to admit that Tang Jing's idea is still feasible.

It is also a cost-effective solution at present.

Chen Du called everyone together and said what Tang Jing thought.

Being able to sleep peacefully at night naturally has no objection.

Only Dong Junwei was a little hesitant and asked Chen Du: "Is your ability enough to support so many materials?" ”

"If it's just plastic, it's not a big problem."

Chen Wei estimated the scale of the entire project and the upper limit of his own capacity, and added: "It really can't be done, so it's better to do it in two days than to do nothing." ”

Dong Junwei nodded: "Do you need me to do anything?" ”

Tang Jing smiled: "Of course, you are also the main labor force, squad leader. ”

Chen Du and Dong Junwei glanced at each other, and they both had a feeling that they had been arranged clearly.

……

Tang Jing's idea was already very mature, but when it came time to actually implement it, problems still appeared.

It's not too difficult, it's just that there is not enough time.

From about three o'clock in the afternoon until dark, everyone did not even see the prototype of the house.

The initial work was all about Chen Duan, and the others couldn't help much for the time being.

Even if it is just a piece of wall that does not need any decoration, because the area is relatively large, it is difficult to make it neat, and the reason why it is easy to make the bottom surface of the flatbed truck in the first place is because it does not need to be precise and neat, which makes the flatbed look crooked.

But not with houses.

It wasn't difficult for Chen Duan to make a plastic plate of similar size, as he said, just a few minutes, but it would be troublesome to meet Tang Jing's requirements.

If the error is too large and the house cannot be closed when it is built, then it loses its meaning.

As a result, he spent most of his time tinkering.

By the time the four walls were finished, the sky had completely darkened, and there was a big battle during the day today, Chen Dui had consumed too much physical and mental power, so he could only put it down first and wait for tomorrow to do it.

……

At the same time, Dong Junwei was not idle.

In addition to heating the iron for Du Jiajia's dough cakes, she also experimented with other materials.

Unfortunately, the materials that can be found at the moment are very limited.

In addition to steel and stone, cotton, wood and plastic are worth trying.

The first thing that came to her mind was plastic.

Let Chen Duan help make a fist-sized plastic ball, Dong Junwei took it in her hand, closed her eyes as before, and slowly injected her spiritual power.

The next moment.

The plastic ball shines greatly.
