Chapter 36: Solution

If the city's tap water supply is still unblocked, Chen Xin can find a way to

take a water pipe from his original home and add water to the water tank. This

is how he used the long water pipe connected to the construction team when the

shelter was built. of.

But now, on the one hand, the construction team has left, and Chen Xin does

not have a long enough water pipe. On the other hand, Chen Xin is not sure

whether the tap water is supplied.

In the month after the meteorite impact, the earth's surface was almost

completely covered by fires and high temperatures, and meteorites fell from

time to time. Whether the water plant can survive such disasters is a question

worth worrying about.

What's more, even if the water plant can be preserved, the government is also

maintaining the operation of the water plant in order to ensure the use of

water for the refuge facilities, but how does Chen Xin fill the water tank of

the refuge?

Water pipe? Chen Xin didn't have such a long water pipe, and only a pile of

1.5-liter mineral water bottles could be used.

Some people may say that it is not enough to use mineral water bottles, but a

few more bottles!

It is correct to say that, but before using mineral water bottled water, let's

briefly explain the relationship between water volume and weight, which is the

density of water.

The density of pure water in the standard state should be 1, that is, one

liter of water weighs one kilogram, and one ton of water has one cube.

Chen Xin’s water tank can hold three tons of water, which is three cubic

meters. He has 30 1.5-liter mineral water bottles in his hand, which means

that if they are fully filled, they can transport 45 liters, a total of 90

kilograms of water, which is approximately equal to a girlfriend weight.

How many round trips are needed to fill the water tank without considering

Chen Xin's physical fitness or time?

This is not a difficult question. The first graders who have learned addition,

subtraction, multiplication and division can calculate this question.

A water tank with a total volume of three tons, converted into liters, is

3,000 liters. Chen Xin can transport 45 liters at a time. After a simple

division calculation and simple rounding, we can conclude that Chen Xin has to

go back and forth at least 67 times to fill him. Water tank.

This is really not a number that makes people feel calm. Who can pick up his

girlfriend sixty times?

If it was ten times eight times, Chen Xin wouldn't consider it, just went out

to find a faucet or clean water source that can still be used, and the

watering is over.

But sixty-seven times, this is really a number that makes Chen Xin no desire

to act.

It may be possible to replenish it several times, but only if Chen Xin can

find a stable water source.

So at this time, he should consider the second option, using the system to

upgrade the refuge's water circulation system, and see if a solution can be

found.

The reason why this plan was not considered at the beginning was because the

system could not be made out of nothing and had to upgrade existing things.

Chen Xin’s refuge itself has no water source. Whether it is an external tap

water or an internal well, this was not prepared when the refuge was built.

Chen Xin did consider digging a well for the refuge, so that even if he ran

out of pure water reserves, he could obtain new fresh water resources.

It was just that when the shelter was built, the construction team requested

by Chen Xin had no well-drilling equipment, and he did not contact the

construction team that can dig wells.

Chen Xin’s city is located in the south of Yan Country, close to Daze.

Groundwater resources are very rich. In the past, many hand pumps for pumping

groundwater were indeed seen in rural areas.

But during the previous construction, due to the schedule issue and the lack

of contact with the construction team, Chen Xin had to give up this idea even

though he wanted to build a well for his refuge.

Now Chen Xin wants to upgrade the refuge's water supply system, whether there

will be an upgrade plan that can mine groundwater, which Chen Yu is uncertain.

But when he thinks of going outside to find water, he has to run sixty-seven

times. Chen Xin can only bet whether there is something he needs in the system

upgrade plan.

Fortunately, the survival system picked up did not disappoint Chen Xin.

"Water shortage system"

"Upgrade plan 1: Upgrade water supply system pipe material, improve sewage

recycling efficiency, water tank volume +2 cubic meters, reclaimed water

quality +1, upgrade required survival points 500"

"Upgrade plan 2: Upgrade water supply system pipe material, improve water

recycling system efficiency, increase pumps, water tank volume +5 cubic

meters, upgrade required survival point 300"

"Note: The available head of the pump is 50 meters. The pump is only used for

pumping water. Based on the refuge, there is no groundwater within 50 meters

of the ground."

Chen Xin breathed a sigh of relief when he saw the appearance of a pump in the

upgrade plan. As for the remarks of the second upgrade plan, Chen Xin just

glanced at it and didn't care.

This is the southern part of Yan Country, a place called Jiangnan Water

Village. This city is close to Yunmeng Daze. The groundwater is rich beyond

imagination. When Chen Xin first built the refuge~www.mtlnovel.com~ but Also

deliberately consider waterproofing and avoid digging into groundwater.

As for whether there is underground water 50 meters underground, this is

something that Chen Xin does not need to worry about, because the place where

Chen Xin lived before had a well equipped with a hand pump, but it is now

abandoned.

Chen Xin didn't think too much, and directly used the survival points

accumulated in this month to start the second upgrade.

Upgraded grid-like lights once again appeared in the shelter, only this time

they covered the water supply system.

And Chen Xin once again witnessed the power and magic of the system, because

just now during the upgrade process, Chen Xin saw with his own eyes a machine

pump made up of grid-like light, condensed and formed in front of his eyes.

Seeing the water pump appeared, Chen Xin couldn't bother to sigh the magic of

the system. He checked the circuit of the pump, then went to the power

distribution room to look at the switch, and then turned on the power of the

pump to start the pump.

This is a very small water pump, the power is not very large, but it still

makes a humming sound when it works.

The noise made by the pump is a bit noisy. Compared with the generator next to

it, it looks like a noisy bear boy, but now Chen Xin is staring at the "bear

boy" nervously, hoping to hear the water flow from the roar of the machine.

sound.

Although he knows that there is underground water underground, Chen Xin is

still a little nervous. What if the water layer becomes a little deeper?

However, "Bear Boy" obviously did not let Chen Xin think about it for too

long. Just when Chen Xin was thinking about what to do if he couldn't get the

water, there was a splash of water in the pump, and soon the sound of the pump

was running. It became abruptly sinking, and the side has grown more than

doubled, and the sound of water was also heard in the water tank embedded in

the wall.

The water is pumped up.
