Zombie Crisis: Survival comes first

"Is that so..." After hearing this, Chen Yu continued to stand back, and then asked Feng Yi: "But didn't it just rain? How did the bucket fill up so quickly? Couldn't the water in it be the same as last time? Right?"

Feng Yi nodded: "It's the same as last time, but if you move it around, it will get dirty easily. Just leave it there and move it away when it is full..."

About a minute passed, and then Feng Yi said again: "Have you rested?"

Chen Yu and Lin Yi nodded.

Then the three of them moved the bucket of water to the back room and stored it inside.

After entering, Chen Yu discovered that this house was different. The furniture had been evacuated, and a large stove was built in the house with a large iron pot placed on it.

There is an assembly line-like device next to it.

Chen Yu walked over, looked at it, and said curiously: "What is this?"

There are several levels from high to low, using a thicker pipe, cut in half and laid out.

"Here...Xiao Lin, please introduce him to me. I'll go upstairs to look for dry towels." Feng Yi waved her hand and walked to the second floor.

Lin Yi walked to Chen Yu, pointed to the top and said, "This fish tank-like device is a reservoir, and the rainwater that is collected is poured directly into it."

Looking at the glass container placed two meters high in front of him, Chen Yu whispered: "Why is it so high? It's not convenient to pour water, right?"

"There is no way. There are too many procedures required for filtration. In the end, it has to be dripped into the bucket. You have to leave a certain height. As for adding water, there are stools anyway. It doesn't matter..." Lin Yi pointed to the corner and said softly. .

Then she continued to the second level and introduced it seriously: "The one here is sealed. Use high-temperature sterilized fine sand to fill the bottle. The water above will enter here and then flow out from the mouth of the bottle."

"Wait a minute..." After hearing this, Chen Yu stepped forward and took a closer look, then turned back and said, "Could this be sand from the river?!"

Lin Yi covered her mouth and said with a smile: "Of course not. These were done by Sister Feng herself. She found some clean sand and stones, put them in a pot to heat, then found some iron sheets and poked some holes in them. Pour up."

"Then add cold water and pour it on, and the stone will crack. Then break it into small pieces, and then grind it carefully with an iron rod to get this kind of fine sand."

After Chen Yu understood, he nodded: "It's really amazing, you can think of such a method..."

Hearing this, Lin Yi followed up and said: "Sister Feng is really powerful. She used to run a very big company and managed more than 1000 people by herself. Her mind is really not that of an ordinary person..."

After finishing his words, footsteps were heard on the stairs. Feng Yi joked: "No matter how powerful I am, I can't compare to you now, my great doctor~"

Then she handed over two dry towels: "Wipe it. As Xiao Lin said, it's hard to find medicine now. It's easy to avoid catching a cold."

Then Feng Yi walked to the stove, lit a fire to raise the temperature in the room, and showed him how to use this device.

"Nowadays, without electricity or machinery, we can only follow the old method of filtering and boiling the food before drinking it."

While talking, Feng Yi took a small bucket and walked to the rainwater that had been brought in just now.

Seeing this, Chen Yu walked over to help tilt it and poured some out.

Then Feng Yi stepped on the stool, added water, and said suddenly: "Nowadays, there is a global blackout, and the number of cars is greatly reduced. Without the exhaust gas and the thick smoke emitted by various factories, the rainwater is much cleaner than before. "

"But it's also not drinkable directly. Even now, after layers of filtration and boiling, we still can't drink too much."

When Chen Yu heard this, he stepped forward and watched the water dripping slowly, and asked, "Is it okay if we drink like this?"

"Of course!" Lin Yi explained with a smile: "Because we mixed some pure water. Although it is difficult to search for supplies outside, we can always find some and mix them together. Even if we drink it, it will be fine. In this way , which can be regarded as solving the necessary conditions for survival.”

Chen Yu nodded and continued to look at the pile of filtering devices in front of him.

After passing through that layer of fine sand, the water came to the last hurdle, a large mineral water bucket, which was cut in half.

Inside is a pile of cotton plus charcoal.

The cotton was on top and the charcoal was on the bottom. Chen Yu took a closer look and saw that it was very thin and should have been scraped off with a razor blade.

Two layers of stockings were tied at the exit to prevent charcoal residue from falling into the water.

After counting, one drop of water can fall out in about one second. Although it is not much, it is already fully automatic and filters continuously 24 hours a day.

Feng Yi came over and explained: "Every two days, a dedicated person will come to heat and disinfect the water and collect it in the water room. When everyone needs water, just take the bucket and pick it up yourself."

Looking at the very clean water in front of him, Chen Yu felt that it was no different from the previous mineral water, at least it looked similar.

"It looks okay, but drinking is not okay~" Lin Yi came over and squatted down: "It has not been boiled, no matter how clean it looks, you cannot drink it directly in the apocalypse, otherwise it is very common for people to have diarrhea and half their life."

"I know, I'll just take a look." Chen Yu nodded and stood up.

After staying for a while, the three of them checked that the water connection device was intact and then began to leave.

Because his attention was focused on Yu Yu, Chen Yu discovered that there were some long pipes placed under the eaves of most houses, about as thick as a thigh, cut in half and placed neatly underneath.

Collected the water.

Feng Yi explained: "These are usually used for watering vegetables and flushing toilets..."

Hearing this, Chen Yu also expressed his understanding that it is not easy to store water for a long time now. Even if you make too much drinking water and fail to find a suitable water tank to store it, it will be affected over time.

It's normal to use dirtier ones like these for other purposes.

After all, not everyone is used to using dry toilets. After living there for these days, Chen Yu also found that most houses have bathrooms. Although they don't have that kind of water pumping device, they can be flushed with rainwater.

Suddenly thinking of something, Chen Yu said: "Where did all the toilets discharge the filth? They wouldn't just find a river to dump it, right?"

Hearing this, Feng Yi stopped, turned around and said immediately: "Of course not. If things like those are discharged everywhere, they will pollute the environment sooner or later over time. If we do this, we will be shooting ourselves in the foot. "

Lin Yi on the side also said: "Some of the sewage pipes in the villa area here have been completed. We don't need to worry about these. It's just that the place where they are piled is in a pit. This pit was dug by everyone."
