    If the tap water supply in the urban area is still smooth, Chen Xin can find a way to connect a water pipe from his original home and add water to the water tank. When the shelter was built before, he used the long water pipe connected by the construction team to add water.  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 still available.

    In the month after the meteorite impact, the earth's surface was almost completely covered by fire and high temperatures, and meteorites fell from time to time. Whether the waterworks could survive such a disaster is a matter of concern.

    What¡¯s more, even if the water plant can be preserved, the government is still maintaining the operation of the water plant to ensure water supply for shelter facilities, but how is Chen Xin going to pour tap water into the water tank of the shelter?

    ? ? Water pipe?  Chen Xinxin does not have such a long water pipe, and all he can use is a pile of 1.5-liter mineral water bottles.

    Maybe some people will say that it¡¯s not enough to fill it with mineral water bottles, the worst thing is to fill it with a few more bottles!

    That is true, but before filling water in mineral water bottles, let¡¯s briefly explain the relationship between the volume and weight of water, which is the density of water.

    The density of pure water should be 1 under standard conditions, 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, which means that if they are all filled, he can transport 45 liters and a total of 90 kilograms of water, which is about the same as a girlfriend's.  weight.

    Without taking into account Chen Xin¡¯s physical fitness or time, how many trips would it take to fill the water tank?

    This is not a difficult question. Any first-grade primary school student who has learned addition, subtraction, multiplication and division can solve 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 it.  water tank.

    This is really not a number that makes people feel comfortable. Who can pick up his girlfriend and run back and forth more than sixty times in one go?

    If it¡¯s eight times out of ten, Chen Xin won¡¯t think about it. He just goes out to find a faucet or a clean water source that can still be used, and fills it with water.

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

    It may be possible to replenish it several times, but the premise is that Chen Xin can find a stable water source.

    So at this time, he should consider the second option, using the system to upgrade the water circulation system of the shelter, and see if he can find a solution.

    The reason why this plan was not considered at the beginning was because the system cannot be created out of nothing and existing things must be upgraded.

    Chen Xin¡¯s shelter itself has no water source, whether it is external tap water or an internal well, which was not prepared when the shelter was originally built.

    ?????????????????????????????????????????????????????????????mbmbmb

    ¡°It¡¯s just that when the shelter was built, the construction team Chen Xin hired did not have well-drilling equipment, and he did not contact a construction team that could drill wells.

    Chen Xin¡¯s city is located in the south of Yanguo, close to Daze, and has very rich groundwater resources. In the past, many hand-cranked water pumps for extracting groundwater could be seen in rural areas.

    But during the previous construction, due to construction schedule issues and the lack of contact with the construction team, even though Chen Xin wanted to build a well for his shelter, he had to give up the idea.

    Now Chen Xin wants to upgrade the water supply system of the shelter. Chen Yu is not sure whether there is an upgrade plan that can mine groundwater.

    But when he thought about having to make sixty-seven trips to find water outside, Chen Xin could only bet on whether the system upgrade plan had what he needed.

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

    ¡°A water supply system that is short of water¡±

    "Upgrade plan one: upgrade the pipe material of the water supply system, improve the efficiency of sewage recycling and regeneration, the water tank volume +2 cubic meters, the recycled water quality +1, the required survival points for the upgrade are 500"

    "Upgrade Plan 2: Upgrade the pipe material of the water supply system, improve the efficiency of the water recycling system, increase the water pump, increase the water tank volume by 5 cubic meters, and upgrade the required survival points to 300"

    "Note: The available lift of the water pump is 50 meters. This pump is only used for pumping water. Based on the shelter, it cannot be obtained if there is no underground water layer within 50 meters underground.groundwater.  "

    Seeing the water pump appearing in the upgrade plan, Chen Xin breathed a sigh of relief. As for the remarks about the second upgrade plan, Chen Xin just glanced at it and didn't care.

    This is the southern part of the Yan Kingdom, a place known as the Jiangnan Water Town. This city is close to Yunmeng Daze. The groundwater is rich beyond imagination. When Chen Xin built the shelter, he also specifically considered waterproofing and  Avoid digging into underground water.

    As for whether there is groundwater fifty meters underground, this is something that Chen Xin does not need to worry about at all, because there used to be a well with a hand pump installed in the place where Chen Xin lived, but it is now abandoned.

    Chen Xin didn¡¯t think too much and just used the survival points he had accumulated in the past month to upgrade plan two.

    Upgraded grid lights once again appear in the shelter, only this time they cover the water supply system.

    And Chen Xin once again witnessed the power and magic of the system, because during the upgrade process, Chen Xin saw with his own eyes a machine pump made of a grid of light, condensed and formed in front of his eyes.

    Seeing the water pump appear, Chen Xin couldn't help but sigh at the magic of the system. He checked the circuit of the pump, went to the power distribution room and took a look at the switch, then turned on the power of the water pump and let the water pump start working.

    This is a small water pump, not very powerful, but it still makes a buzzing sound when it works.

    The noise made by the water pump was a bit noisy, and compared to the generator next to it, it looked like a noisy naughty child. But at this moment, Chen Xin stared at this "naughty child" nervously, hoping to hear the flow of water from the roar of the machine.  sound.

    Although he knew that there was underground water, Chen Xin was still a little nervous. What if the water layer was a little deeper?

    However, the "naughty kid" obviously didn't let Chen Xin think about it for too long. Just when Chen Xin was thinking about what to do if he couldn't pump the water, the sound of rushing water sounded from the water pump, and soon the sound of the pump running stopped.  It suddenly sank, and the sound of water also sounded from the water tank on the side that had more than doubled in size and was embedded in the wall.

    Water, pumped up.  (Remember the website address: www.hlnovel.com
