Doomsday: Humanity shrinks 100 times

Chapter 245 Electrification
The trip was smooth, the only trouble was climbing the stairs.

For them, climbing a seven- or eight-story building is like landing on the moon. It would probably be impossible to climb up there by manpower.

However, it is not so troublesome now because Han Yingying and Gu Yu are here.

With Han Yingying's cooperation, everyone was able to fly, but for safety reasons, they decided to fly up from inside the building.

The residential building they explored was exactly 8 stories high, and three months later, it was already emitting a musty smell.

Occasionally, you can see some moss growing in the corners.

Spider webs can be seen everywhere, and plants and insects are gradually taking over the place.

Since they are not in a mimicry state now, there is still some threat from insects. It may not be easy to escape unscathed if they are trapped in a spider web.

The seven of them tried their best to stick to the wall and carefully groped their way towards the top floor.

In the middle, I came across an open door. I don’t know if it was opened before the end of the world or opened by someone later.

Although he really wanted to go in and take a look, Lu Yuning was worried that there might be small animals inside, so he had to give up in the end.

The seven people quickly flew to the roof, and on the platform upstairs, in addition to a solar panel, there was an unexpected surprise.

There are actually people growing plants here, but it looks like it was done before the apocalypse, as several plants have withered due to lack of water.

However, there is still one plant that looks like it is alive, and if I am not mistaken, it looks like a potato.

Potatoes are not cold-resistant crops, but the temperature is not that low now, and its branches and leaves look a little withered.

However, the area near the roots is still relatively fresh, which means that the tubers buried in the mud should not have rotted. If they can be dug out, they can be planted.

Lu Yuning hurried forward and dug out the potato.

“It looks like it could be used for planting.”

"Put it away and wait for it to sprout on its own."

Wu Xiao nodded and threw the potato tuber into the space. He guessed that Dong Yongfang would be very happy to see this thing.

After processing the crops, several people gathered around the solar panels.

This thing looks brand new and has a long lifespan, so there's no need to worry about it breaking down.

All they have to do is make use of these solar panels and then make an electric power transmission device to transport electricity to the school.

Everyone has decided to set up an outpost here temporarily and return to the Weird Light Base after the gunpowder production process is completely quantified.

Several people walked around the solar panel and found the usage specifications underneath it.

"This solar panel has a power of 270W."

“It’s more than enough electricity for home use.”

"Well, I don't know if it's equipped with things like inverters and batteries. However, the power of a solar panel is quite high, so logically speaking, these things should be installed as a set."

"Let's look for it nearby."

After a while of discussion, Lu Yuning remained optimistic.

In fact, he was more worried about how to connect the circuit to the laboratory, or to open another factory here?
It's not impossible, but it's a bit troublesome to run back and forth, and there are some safety risks.

The few of them soon made a discovery. Following the wiring of the solar panels, they found a huge power distribution control box.

If nothing unexpected happens, the entire power distribution facility should be inside.

Logically, the equipment should still be running, but there was no sign of it. It seemed that I had to open the control box and take a look. The box was already a bit rusty, and I had no choice but to destroy the entire shell.

The moment he opened the outer shell, Lu Yuning saw that the battery indicator light inside was flashing green.

"Great, it looks like it can be used right away."

"Wow, there's electricity, but I don't know where it goes."

Zhang Xinyue said: "Don't worry, turn this thing off first, otherwise it won't be fun to get an electric shock."

Lu Yuning nodded.

The main switch valve for the entire circuit is right next to the distribution equipment, but the switch does not seem to be that easy to open.

"If I had called Wu Dongxi earlier, he might be able to pull this thing down."

Lu Yuning looked at the switch of the solar power distribution equipment and said somewhat depressedly.

This switch stumped Lu Yuning for a while, but everyone quickly came up with a solution.

Make a simple lever device.

This switch is not push-type. There is a handle on it for easy pulling up and down. A rope can be tied to this handle.

The other end depends on Wu Xiao's special ability. He just needs to find a larger heavy object and tie it up.

Put it at a high place, and then let Zhang Muyan eliminate the friction of the stone. In this way, the kinetic energy generated by pushing it down from a high place should be enough to pull down the switch.

He would deal with it for now, and later Lu Yu planned to make a real lever switch, or a hand-cranked opening and closing device through gear difference.

"Snapped"

As the stone fell, the switch on the device was pulled down and the indicator light went out.

This way we can find a way to connect the wires to the laboratory.

But this job is not easy.

The distance is more than 200 meters. It is almost an impossible task for them to connect a 200-meter-long copper wire from the roof to the ground and then to the laboratory.

So at first they didn't think of just pulling the wires through, but rather using the existing circuit.

The city's power supply system is all in a circuit network, which means that there must be a closed line leading to the laboratory from the community, and this is what they have to do.

It is neither difficult nor easy, the key is whether the line can be easily identified.

Lu Yuning followed the electrical wires all the way down. First, he figured out the wiring in the community, and then he had to find the circuits at two locations.

The power inlet of the community must be connected to a nearby cable. As long as you can get the electricity to the cable, you are basically half successful. Then you can find a way to find the cable connected to the school.

There may be a broken circuit in the middle, and Lu Yuning can only rely on changing the direction of the wires.

It was imagined that this task should not be too complicated, but when Lu Yuning found a power supply box in the community, he suddenly felt that their idea seemed too simple, as the circuit inside was quite complicated.

This was completely beyond his knowledge and he had no idea how to respond.

Finally, Zhang Muyan was found.

"Although these power grids look complicated, as long as you can distinguish the neutral wire and the live wire, the final effect is the same, and the circuit breakage you mentioned will not occur. The only thing you need to pay attention to is to disconnect all irrelevant circuits to avoid unnecessary power consumption."

Lu Yuning breathed a sigh of relief. Since there were professionals, he didn't have to worry about it. It was also good to be a hard laborer.
