My Doomsday Shelter Unlimited Upgrades

Upgrade direction [-], this can be useful. Energy storage can also reduce the size of the water pump. In the future, the water pump can be taken out for pumping water anytime and anywhere. If it is combined with the water purification system, it may be possible to go outside to pump waste water back to purify it in the future, saving money. I scooped up pots and pots by myself, but there is no need to upgrade for the time being.

As for the upgrade direction four...

Chen Yang didn't read the specific instructions, and chose to give up when he saw the need for 1500 survival points.

After looking at it for a while, Chen Yang came to a conclusion.

This water pump is enough for now, no need to continue to upgrade.

Chen Yang put the water pump into the system, walked out of the room, and prepared to install the water pump on the roof first.

Jiang Yanbing was no longer lying on the bed, but sat up again.

Viewed from the side, Jiang Yanbing's slender figure can be seen at a glance, with graceful and charming curves.

Chen Yang has never met someone who looks good from any angle.

"Why don't you lie down? Isn't it more comfortable to lie down?"

Chen Yang knew the reason and asked, and typed a haha.

Jiang Yanbing turned his head in a snap, gritted his teeth and glared at Chen Yang viciously.

"It's okay, you can't lie upright, you can lie upside down! Just point your head there." Chen Yang pointed to the opposite direction.

Jiang Yanbing was stunned for two seconds, then came back to her senses, Hongxia landed on Suojian Heights again.

If you point your head in the direction of the control room, what you can see is the inside of the clothes. If you point your head in the opposite direction, what you see...

"you!"

Jiang Yanbing felt that his head was going to pass out from the heat, and he was going to lose his sanity. He picked up a piece of clothing at hand and was about to get off the bed and hit Chen Yang.

Chen Yang walked quickly to Jiang Yanbing's side, put his hands on Jiang Yanbing's shoulders and held her down, preventing her from standing up.

"Okay, I joked too much, sorry."

"I'm going to get the water pipe. You can take a shower when the water pipe is connected."

Jiang Yanbing's shoulders were even hot, and he lowered his head involuntarily, but his reason was pushed back by this pressure, and the hand holding his clothes did not slap him for a long time.

"I...I forgive you."

After finishing speaking, Jiang Yanbing suddenly raised his head, looked directly at Chen Yang, and pointed at Chen Yang with his pale index finger:

"We're not familiar yet, so we can't make fun of me, understand?"

Chen Yang smiled: "If you can't open it, you can't open it."

Jiang Yanbing stared at Chen Yang for a while:

"I don't believe it, you swear!"

Chen Yang was a little dumbfounded. How could the Bingshan Goddess recognized in the campus still have such a side, and he even had to swear? Isn't Jiang Yanbing in his parallel world and this Jiang Yanbing the same attribute?

"Is this what you usually do in school?"

Immediately, Jiang Yanbing felt a little embarrassed, and hesitated for a few seconds:

"You...don't worry! Do you swear?"

Chen Yang had no choice but to raise his right hand,

"I swear, I will never make fun of Jiang Yanbing again. If I break my oath, my shelter will be struck by lightning!"

After finishing speaking, Chen Yang added:

"This refuge is more important than my life, so it's okay."

Jiang Yanbing blushed, feeling something strange for a moment, but couldn't put it into words, so she nodded stiffly.

Chapter 58 Double Lightning Protection Design, Water Tank Upgrade

Chen Yang came outside the house again, and now there is one more goal besides installing the water pump.

Install lightning rods.

A man's mouth is a deceiving ghost, if Jiang Yanbing really stays here, it's impossible not to tease him.

Don't take advantage of the bastard, looking at Jiang Yanbing's unspeakable anger, Chen Yang thought it was fun.

I found something more interesting than playing with the water pump, that is...

Of course, putting aside the motive of joking, the words just now did wake up Chen Yang.

The lightning rod still needs to be installed.

At present, the paint protection on the outer layer of the refuge should also have the function of insulation and anti-electricity, but Chen Yang doesn't know how effective the insulation is.

Chen Yang is not stupid enough to use wires to test the effect. If the insulation effect is good, it is the circuit that is damaged. If the effect is not good, it is the shelter that is damaged.

When there is rain, there may be thunder. Lightning rods are also one of the necessary facilities in a building. Chen Yang really didn't think of this before.

Bulletproof glass can protect against bullets, but if the number of bullets hits is too high, cracks will appear in the bulletproof glass. The same is true for his shelter.

A shelter whose material has only been upgraded once is certainly not impervious to water and fire. If there is a lightning strike, there is no guarantee that the shelter will be [-]% safe. Making a lightning rod can achieve the effect of double-layer defense.

Although the lightning rod has the word 'avoid', it is not possible to avoid lightning strikes by installing a lightning rod.

Rather than calling it a lightning rod, it is easier to understand it as a lightning rod.

The location and time of the lightning strikes are not fixed, and it is possible to strike passers-by or residents if you are not careful. The effect of the lightning rod is to attract these random lightning strikes to the lightning rod. From the perspective of others, this is indeed true. It achieves the effect of 'avoidance'.

After the lightning rod attracts the lightning, it guides the electricity to the ground through a wire or a grounding device to prevent objects from being struck by lightning.

Chen Yang walked out of the shelter about ten meters away, planning to place a lightning rod here.

Anyway, there are no other residents here, so instead of directing the lightning to the roof of the shelter, and then sending the electricity to the ground through the shelter, it is better to direct the lightning to the ground.

The production method of the lightning rod is very simple. Chen Yang spent more than a dozen units of iron to make a particularly slender iron rod, which is about one meter higher than the height of the shelter, and erected the iron rod on the ground. .

This is not over yet, Chen Yang walked out about five meters away, dug out a small pit more than one meter deep, and made several copper bars at the same time, buried the copper bars vertically in the ground, The copper bars are all connected into one body, and then a thicker copper wire is drawn out to connect the copper bar with the iron rod.

Lightning is more powerful than high-voltage electricity, and the copper wire used must be thick enough so that the resistance of the wire is small, and it will not malfunction or cause a high-temperature fire when conducting electricity.

Chen Yang put a layer of insulating wooden boards on the outside of the copper strips, and refilled the soil, and a simple homemade lightning rod was ready.

The lightning is attracted by the iron rod at the high point, and the copper wire is introduced into the copper bar buried in the ground to dissipate the electricity into the ground, and the upper wooden block is made of a layer of insulation to prevent the current from flowing to the surface.
