My Doomsday Shelter Unlimited Upgrades

"Meow meow!"

The sheriff happily jumped side to side twice, and then licked the filtered water in the basin twice.

can drink!

Chen Yang was overjoyed, and impatiently took a sip of some water.

"The taste...it's okay...it feels like ordinary mineral water?"

Although it is not as magical as quantum water, the filtered water has fully reached the level of drinking or daily water.

This kind of water is like ordinary mineral water or boiled water.

Colorless and tasteless, it cools and quenches thirst, and there is no sign of mutation after drinking it!

I have also tasted it, and with the affirmation of this cat brand water quality tester, the water quality of the filtered water must be no problem.

Now that the water quality is fine, all that's left is to connect the permeation filter to the water pipes and tank!

Then, it’s time to go big!

He rewarded the sheriff with a small piece of boiled potatoes, and Chen Yang moved the permeation filter to the second floor.

There is currently a lot of spare space on the second floor, which is just right for this kind of thing.

The waste water outlet of the filter runs through the shelter wall all the way to the sewage pipe below, while another outlet for pure water needs to be connected to the water supply tank.

This water tank must be large in volume, the kind that can hold a lot of water!

The original top water tank has a capacity of 100L, which is used to hold quantum water, and now it also needs to be expanded.

He can produce 100L of quantum water a day now, and if he uses less, the rest has to be stored in the water tank.

Upgrade Direction 100: To increase the capacity of the water tank, [-] survival points are required.

After using more than 20 units of alloy steel, the survival points required to expand the water tank have been reduced from 100 to 20.

"upgrade!"

[Records]: Survival point -20, alloy -22.

【Upgrading, please wait patiently. 】

The water tank placed in the control room becomes bigger and bigger with the white light, and finally becomes a cuboid water tank of 1m1m1.5m.

1.5 cubic meters!

This is the upgraded water tank volume.

One cubic meter of water equals one thousand liters of water, or one ton of water.

1.5 cubic meters, 1.5 tons, even if all the quantum water is stored every day, it will take 15 days to fill it up!

Chen Yang is quite satisfied with the effect of this capacity.

Moreover, he is completely confident in the load-bearing capacity of the shelter, and he is not worried about crushing the shelter at all.

The load-bearing capacity of a general residential building is 200kg per square meter, which is 2 tons per square meter.

However, the products produced by the system must be high-quality goods. The real load-bearing capacity of the shelter is estimated to reach four to five tons per square meter.

It is not a problem at all to put a water tank of more than one ton on this square meter.

After the quantum water tank was upgraded, Chen Yang followed the same pattern and made an identical water tank.

This time it costs less survival points than before, because there is no need to coat the outside with a layer of anti-corrosion material.

The two water tanks are placed side by side, and Chen Yang even put a label on them, so as not to forget which is which in the future.

The permeation filter was placed in another corner of the control room, keeping a little distance from the two water tanks as much as possible.

In this way, it is more convenient for the water to flow back and forth, and the flow speed is faster.

After the two water outlets of the filter have been installed, a water tank for waste water will be placed in the rest.

The waste water is loaded into the water tank, and the water tank is connected to the osmosis filter again, so that the waste water is poured into the osmosis filter little by little manually.

Permeation filters do not use electricity, but do have an activation time.

Once the water in the filter is completely filtered, it takes another 5 minutes to start up, which is annoying.

And the location of this water tank must be considered clearly.

This water tank is not as simple as before.

Chapter 124 Jiang Yanbing's singing, the buried water tank is built.

Chen Yang first ruled out the idea of ​​putting the waste water tank on the second floor.

Once the water tank is damaged, it will be too painful to clean up the waste water flowing all over the place.

It is best placed on the first floor, and it would be even better if it could be buried underground.

"Wait, underground?!"

Chen Yang had a flash of inspiration:

"If we build a rainwater collection system by the way, this kind of waste water can be filtered into pure water, even if it is acid rain, it will definitely be fine."

Idea works!

Chen Yang didn't draw any ink, so he took the time to go outside and began to choose the location to bury the water tank.

In the future, the shelter will definitely be expanded, and there will be other equipment. The location of the water tank should not be too far from the shelter.

Chen Yang walked tens of meters away from the refuge, found an open space, and planned to place the water tank here.

The first step is to dig a hole!

Taking out the alloy shovel, Chen Yang started to do his old job.

Hardworking people have already boarded the tower crane,

And some cats stretched themselves under the covers!

As for which cat it is, I know, but I won't say!

Chen Yang also couldn't complain about the sheriff's piggy style.
