The strongest reserve for the doomsday

The book continued, people eat grains, and they will inevitably have to pull rice every day.

Although the first two are very important, the last two are also very important.

It's good that you have water to eat, but you also have to have a suitable place to excrete, otherwise if you defecate in the open, the living environment will deteriorate rapidly. It can even threaten the survival of people.

From humans, we evolved not to defecate casually, which is also the embodiment of civilization.

And I'm here, because I'm on the 10th floor, theoretically, there won't be a raw sewer blocking into my 10th floor, so I'm not very worried about the sewer here.

When a crisis erupts, the environment of the city's sewers is expected to be very bad, but the sewer itself is still sufficient, which means that the sewers will not be unusable.

So, I guess I should be fine with normal use of this sewer. If it's blocked, just go down the drain to the next level. Anyway, as long as it doesn't pollute my layer, it's fine.

After all, it's the end of the world, and my comrades downstairs should have no opinion on the leaky sewer. But in fact, I don't have any residents downstairs, and it seems that the most luxurious and expensive real estate in the entire Little Raccoon City is not selling very well.

However, you don't have to worry about the sewer being blocked, but the other thing I'm worried about is that something may come up with the sewer!

The sewers are all connected. When the time comes, some small creatures carrying the virus will inevitably climb up along the sewer, which is not a joke.

When you are in the toilet bowl and the front machine gun is firing and the war is raging in the back, a mutated centipede climbs up and gives you a mouthful, wouldn't that be angry.

So in order to prevent this from happening, I called the plumbing company again and replaced all the sewer pipes downstairs with cast iron. In addition, titanium alloy filter and check valve have been added. That way you can sit back and relax.

And the sewer upstairs, I'm sorry, I've blocked it.

It's the end, and there's no one up there anyway, so I guess it's sealed. It's a precautionary measure, if I get a ceiling leak, I won't suffer. So if you don't do it, you can directly seal the upstairs and sewers. And the rainwater drainage upstairs didn't move. This continues to give it residual heat, which can solve the problem of rainwater above.

These sewer projects were carried out by the workers as soon as I came to this place, so I didn't have to bother the fat man and Zheng Yan, and I got everything done properly behind the scenes.

"Then the 10 tanks you mentioned are a bit bluffing!" the fat man interrupted me and asked.

"Where did you get this thing?" Zheng

Yan also dragged her cheeks with her hands and looked at me puzzled.

"It's hard to say, but it's easy to say. There are few people who use this thing here, and only the northwest of our country uses more people. But there are more people who use it, and this drawing is available. And there are a lot of hardware processing factories on our side, I directly took the drawings to the processing factory and directly gave them

to the processing factory" "I see, are you because the factory needs 10 to process for you, so you have ordered so many?" Zheng Yan seemed to be aware.

"Haha, you know that. At the beginning, I wanted to order 3, but the boss said that 3, the money for opening the mold was not enough, at least I wanted to make 20. I said that it was useless for me to buy 20, and finally I added 200 yuan to the unit price, and 10 were also made for me, and tomorrow, this hardware boss will send it over. "

I said that the hardware boss is so kind, and he will customize it for you." Zheng Yan suddenly realized.

But after all, Miss Ben didn't want to drink the collected rainwater, so at most she used it for me to bathe. Zheng Yan doesn't seem to trust my filter device very much.

"Haha, whatever you want. But if you don't drink this, then reserve some mineral water, take advantage of the fact that it's okay now, and I'm tired of Zheng Meinu to help contact the mineral water

" "Hmph, I know how to call people" I saw Zheng Yan stretch out her little hand and put it in front of me, and then said: "Money

" "Damn, when is it, still thinking about pit my money"

I took out 2000 yuan from my wallet, and she was not ambiguous, and took all 2000 yuan directly, took it away...
