My Doomsday Shelter Unlimited Upgrades

System Comments: So simple that there is no introduction, I won’t tell you whether it can be used!I understand everything!

"Upgrade direction one, upgrade quickly!!!! Didn't you see that I'm still holding high-voltage electricity here???"

Chapter 34 Pulling the Power Grid and Opening the Era of Tunnel Warfare

After 10 units of alloy steel and 70 survival points were deducted for upgrading, Chen Yang hurriedly turned off the voltage transmission switch, heaving a sigh of relief.

He once read a statistic that the number of abnormal deaths in the country is about 320 million every year, and the number of people who die from electrocution is as high as about 1.

Such a number sounds insignificant, but it is actually quite scary when you think about it carefully. There are all kinds of abnormal deaths, and the death by electrocution alone accounts for [-] in [-], which is enough to illustrate the importance of electricity safety.

As long as nothing happened, he made the right bet this time, and he will never do such a dangerous thing again in the future.

【Step-up and step-down transformer (excellent)】:

Buck-boost from 220V to 1000V/30V can be realized.

Loss: 1000W/h

Upgrade Direction 500: Change the material of the transformer, greatly increase its durability and reduce power loss, [-] survival points are required.

Upgrade direction two: add a control system, change the transformer transmission voltage in real time without power off, reduce the size of the transformer, and require 500 survival points.

Additional attributes: Noise -95%

"Another good attribute!"

Although the transformer is only of excellent quality after the upgrade, Chen Yang is very satisfied with the additional attributes added, and it can even be said that he is overly satisfied.

He has considered the noise problem of the transformer before. He will go crazy sooner or later when he listens to the rumbling sound every day. It can reduce noise pollution, but it will be a lot of trouble when he wants to control the transformer.

This is great, the noise is -95%, the transformer can be installed in the indoor space, and the transformer can be controlled at any time, and there is no need to worry about the rumbling noise all day long.

Chen Yang impatiently put the transformer into the system backpack, and specially divided a small space of about 10 square meters in the living room as the control room for various facilities of the shelter, and placed the transformer there.

The upgraded transformer is not small in size, but it is used in a fool-like way. Unlike the transformers mentioned in the book, there is no need to pay attention to the wiring method. This transformer only has three ports, one for input 220V voltage, one of the other two ports outputs 30V voltage, and the other outputs 1000V voltage, and it can be used after plugging in. It is very convenient, and it must be the credit of the system.

After plugging in the wires, Chen Yang upgraded the wire mesh grid. The materials required for the grid upgrade are still mainly copper and silver. The grid can be simply regarded as wires without insulating plastic wrapping.

The electricity system of the power grid is still connected to the refuge house through underground wiring, and the plug is connected to the 1000V socket. After confirming that the connection is correct, Chen Yang carefully turns on the switch of the transformer.

The transformer starts to run normally after a few seconds of power-on time. Even if it is fully loaded and outputs a high voltage of 1000V, the sound produced by the transformer at this time is still not as loud as that of a computer case. Listen, there is no noise at all.

When he came outside the house, Chen Yang forcibly woke up the sheriff who was sleeping in his pocket, and threw a small piece of meat on the power grid from a long distance away.

As soon as the meat touched the power grid, it immediately made a "stab" sound, and after a shock of sparks, a small piece of wolf meat fell to the ground, and the side of the meat that touched the power grid had become burnt.

The sheriff hadn't seen this thing before, so he quickly got into his pocket in fright, and only poked out two cat ears and a pair of big eyes to look around.

"You can't touch this thing, do you know that? If you touch it, it will become a whole roasted cat."

"Meow meow meow!"

After explaining to the police chief, Chen Yang unplugged the 1000V plug, plugged it back in to the 30V voltage, and reset the air switch.

Just now, because of the electric shock caused by the 1000V high voltage, the power consumption in the circuit was overloaded in an instant, and the air switch tripped naturally. This is the biggest problem caused by insufficient power.

Can the 1000V high-voltage power grid be used?

works!But it can only be used for a while, and then it will trip. If the air switch for overload tripping is not installed, the generator will be damaged.

The 30V voltage can be used as an alarm function all the time, but if there is a monster attack in the future, the 1000V power grid must withstand it for a long time, and the power problem must be solved within a few days, and all solar panels must be made.

Chen Yang recorded his goals in his notepad to prevent himself from accidentally forgetting. It is a common occurrence to forget the other end. A good memory is not as good as a bad pen.

Currently there is only one grid fence, and Chen Yang decided to build the other three fences tomorrow.

Firstly, the weather is late today, and secondly, there are not enough materials today. The construction of the barbed wire fence is extremely expensive. In addition to upgrading the power grid, he has no direction to upgrade the barbed wire. This is also due to the limited materials. Survival What can be saved is saved, what if there are fewer survival points tomorrow?

There was still a while before going to sleep, Chen Yang broke out some big Lieba bread, heated up the meat skewers left over from the noon roast, and made a simple rougamo. After each person and cat ate, Chen Yang thought How to design the escape route of the shelter.

Although the safety level of the refuge was not at the same level as the previous few days, emergency escape routes were still required in case of accidents. In case some perverted monsters appeared, he didn't want to be a turtle in the urn again.

The legends and myths of people in Tazai sounded inspirational, but he still felt that his life was more important. If the things in the shelter were gone, it would be a big deal to pick them up from scratch.

When it comes to escape strategies, the first thing Chen Yang thinks of is helicopters and armored vehicles.

Not only in the end of the world, but in Hollywood blockbusters, those villains also sit on this kind of thing when they escape. Although they are stopped by the anti-human protagonist in the end, it is enough to show the effectiveness of this escape method.

This idea is not a fantasy. With the blessing of the system, maybe he can float to outer space in the future, plant potatoes on the moon, let alone a helicopter or an armored vehicle. Development time and opportunities.

After Chen Yang recorded this idea, he began to think of some feasible escape plans in the near future.

What should I do if I am indecisive?Start the tunnel battle directly!

Digging tunnels to escape is also an old escape method. Although it is a bit stupid, it is practical. When fighting devils, every household dug a lot of escape tunnels, which can fool the enemy around.

Chen Yang did what he said, and the entrance of the tunnel was placed in the corner of the control room. Choosing this location to dig the tunnel can minimize the damage to the foundation or load bearing of the house caused by digging the tunnel.

After breaking down the floor of the house into pieces, Chen Yang started digging the tunnel.

The system does not have the function of automatic excavation, just like digging a trench, he can only do hard work with one shovel at a time. Fortunately, the soil dug out can be collected into the system. The time was wasted running back and forth on the road, and now only digging but not throwing, the efficiency has increased several times.

Chen Yang didn't dig the tunnel too deep, he only dug less than two meters. If he dug too deep, a landslide might occur. At that time, he didn't even need to prepare the coffin, he just gave him a wave Buried alive.

In order to further prevent such things from happening, Chen Yang deliberately dug the tunnel a little narrower to maintain the tension of the land as much as possible. The soil collapsed, and there were stone walls to resist it, so that he would not be buried in the tunnel.

The size of the tunnel is probably only enough for one person to pass through. Although you can't stand in the tunnel, you don't have to crawl. You can still move quickly in the tunnel while squatting and bending over.

The excavation speed was fast, and the materials were of course used up quickly. After about two hours, Chen Yang dug out a distance of about 20 meters, and the stones were used up.

After wiping off his sweat, Chen Yang returned to the refuge and decided to end the day's action. Even if he drank quantum water and strengthened his physique, he couldn't stand the long hours of hard work, so he still had to rest when it was time to rest.

According to his plan, the tunnel must be dug at least two or three kilometers away, and an exit will be added every three to five hundred meters to ensure that he can escape from the safe area under different circumstances. Therefore, tunnel excavation is not a small process. Boil the frog in warm water, and the water will flow in a long stream.

After washing, Chen Yang took off his clothes and hurriedly fell asleep.
