My Doomsday Shelter Unlimited Upgrades

This rotation exerts a centrifugal force on the water, and at the same time, a vacuum and low-pressure area is generated at the center of the blades. The pressure inside the pump will be lower than the external atmospheric pressure, and the water will naturally be squeezed out of the pump.

Chen Yang made three small blades out of alloy, making it look like a computer fan, and installed the fan on the rotor of the motor. This is the turbine blade of the water pump.

Chen Yang rummaged through the system backpack and found a beer can. This kind of can is relatively large and suitable for use as a water pump.

Open the top and bottom of the can, make a water outlet on one end, and a water inlet on the other end, insert plastic hoses at both ends, and insert turbine blades into it, and fill up all the leaking points, a simple self-made water pump is ready up.

If it was before the end of the world, Chen Yang would definitely post a Moments to show off his hands-on ability, and maybe attract a few beautiful sisters to comment and like, but now the conditions are not allowed.

There is a beautiful younger sister outside, but Chen Yang upholds the thinking that more things are worse than less things, and forcibly suppressed the urge to show off.

The system did not pop up an upgrade prompt, so Chen Yang planned to go back to the kitchen and bring two bowls to test the effect of the water pump after filling it with water. This is how it was upgraded many times in the past.

As soon as he opened the door, Chen Yang saw Jiang Yanbing lying on his back on the wooden bed in the living room.

Chen Yang didn't intend to stay, but the two white and round things and one of the unfathomable canyons really caught Chen Yang's attention.

At this time, Jiang Yanbing was lying on his back with his head facing Chen Yang. He didn't know whether to say that Jiang Yanbing was thin or that the T-shirt was too loose, anyway, the scenery inside was basically unobstructed.

As for looking down, you can't see it.

Compared with that kind of naked scene, Chen Yang prefers this kind of half-covered feeling. The so-called still holding a pipa half-covered face, there is a reason for the ancients to write this way, and hazy beauty is the real beauty.

Jiang Yanbing heard the sound of the door opening but didn't hear the footsteps walking for a long time. Curiously, he turned his head and glanced behind him, just in time to see Chen Yang who was admiring him.

Jiang Yanbing didn't know what happened at first, but he immediately realized what was going on, and where Chen Yang was looking, his face turned red, and he sat up directly, covering his chest, with a pair of silver teeth It was almost crushed.

"you!"

Chen Yang was a little surprised. He thought Jiang Yanbing would "meow", but he didn't expect to be so calm.

Chen Yang doesn't know if it's true that one white covers all ugliness, but this time Chen Yang is clearly aware of a shortcoming of girls with fair skin.

I can't hide my blush.

For people like Jiang Yanbing, even if they are covered with a layer of soil, the blushing force can't be covered, even if it is only a little red, it can be seen at a glance.

But Chen Yang had never heard of Jiang Yanbing's shy physique in front of his roommates before?

If Jiang Yanbing liked to blush when he was fine, his roommate, Fatty, must have blown to him more than 100 times, such as 'Look at my goddess, she looks even more beautiful when she blushes' or something like that.

Besides, he said it clearly in the morning. He read it once. Not only did Jiang Yanbing not blush at that time, he didn't even have any psychological fluctuations. It seemed that a nun who saw through the world of mortals even gave him a wave of rational analysis. Now Why did it change again?

Chen Yang didn't bother to guess, and he couldn't guess. First of all, Jiang Yanbing's motive for liking himself was ruled out. How could he fall in love with someone else one day?

Although some girls just fell in love with one yesterday, liked one today, and decided on one tomorrow. Their hearts are like the police station in Gotham City, where people invade every day, but Chen Yang thinks that Jiang Yanbing should not be that kind of person.

As for other reasons, Chen Yang couldn't think of any other reason, so he could only attribute it to a previous conclusion:

Women are fickle animals.

In addition to this conclusion, Chen Yang also said with deep emotion that women not only delay the speed of drawing swords, but also delay the speed of learning!

Just looking at this for a while, and wasted a few more minutes, isn't it delicious to play with the self-made water pump?

"What are you?!" Chen Yang preemptively struck.

"Don't think that you can stay with me and eat and drink for free, this trick doesn't work for me!"

Jiang Yanbing's bright eyes were wide open, and her light red lips were parted, as if she couldn't believe her ears in a daze.

"Okay, okay, I'll forgive you this time, and think about whether to leave or stay."

Chen Yang stretched out his right hand and waved it, with a helpless expression:

"Come and let me know when you think about it, and I'll arrange a job for you then."

After finishing speaking, Chen Yang gracefully stepped into the kitchen, quickly took out two small bowls and returned to the control room, leaving Jiang Yanbing messy alone.

After taking the small bowls, Chen Yang poured quantum water into one of the bowls, simulating it as a water source for pumping, and turned on the switch of the electric motor.

The motor drives the turbine to rotate rapidly, and the air in the water pump is blown out of the water pump from the water outlet. Due to the difference in pressure, the water pump first absorbs water from the small bowl filled with water, and the water entering the water pump is then discharged through the water outlet. Squeeze into another small bowl.

The moment the water dripped out of the water outlet, the system prompt sounded.

【Simple water pump】:

The self-made simple water pump has low pumping efficiency.

Upgrade Direction 200: Increase the metal casing, change the structure of the water pump, and greatly improve the pumping efficiency. [-] survival points are required.

Upgrade Direction 500: Fill in the intelligent control system, which can control the water pressure and water flow in real time, and requires [-] survival points.

System comment: We do not produce water, we are just porters of water!

"okay!"

Chen Yang turned off the switch of the electric motor, and drank the quantum water in the small bowl in one gulp.

Tsk, Pepsi flavor.

The first way to upgrade is that there is no need to think about it. After Chen Yang placed some basic materials such as iron alloys and plastics, he used 130 survival points to upgrade the water pump.

After a burst of white light, a silver-gray water pump covering an area of ​​about half a square meter appeared in front of my eyes.

[Ordinary water pump (ordinary)]:

Flow: 10 cubic meters per hour

Power: 1500W

Upgrade Direction 300: Change the material of the water pump, greatly increase the durability of the water pump, and greatly increase the required [-] survival points.

Upgrade Direction 500: Fill in the intelligent control system, which can control the water pressure and water flow in any place in real time, and requires [-] survival points.

Upgrade direction three: add an energy storage system and greatly reduce the volume of the water pump. After charging, it can be used wirelessly. 1000 survival points are required.

Upgrade direction 1500: Change the structure of the water pump, greatly increase the pumping efficiency and reduce power consumption, [-] survival points are required.

System Comments: Produced by the system, it must be a high-quality product, just smoke it!

Chen Yang looked at the appearance of the water pump and thought about the three new upgrade directions.

Upgrade direction one, change the material, this is useless, he plans to place the water pump inside the shelter.

Upgrade direction [-], you can control the water pressure and flow at any place. This is quite useful. If the shelter is built into a high-rise building in the future, you can send water without secondary pressurization. Just use a single water pump to solve all problems. question.

But now the shelter has only one floor in total, and the effect of upgrading is not particularly obvious, so rule it out.
