Doomsday disaster: Start by building a shelter

The next day.

The temperature outside continued to rise.

By noon, it reached about 55 degrees.

Su Wu discovered through the reconnaissance of the drone formation that almost all wild plants and crops in the entire Jianghe City and its surrounding areas had withered and were facing extinction. A large-scale reduction in surface grain production, or even a total crop failure, was inevitable.

"The environment outside is not optimistic."

"Fortunately, it seems that most people here have successfully hidden in the shelter, so there won't be any major problems."

In the Doomsday Chat Group.

Su Wu shared the pictures taken by the drone.

The desolate urban area and the withered farmland inside aroused a wave of resonance.

"It's the same here. Basically everyone has moved into the shelter."

"It's just that the requirements of the official shelter are very strict. It's not allowed to bring too many things in. The place to live is also eight people in a room, which is narrower than the dormitory when I was in school."

"Now there is no entertainment except playing with mobile phones all day long."

This is the complaint of an ordinary person who hid in the official shelter.

His personal safety is not a problem, but the quality of life has fallen to the bottom. All the belongings that had been accumulated, except for a few valuable items that could be carried with him, could only be abandoned in the house on the surface.

If Su Wu had not obtained the doomsday survival system, it is estimated that his experience would not be much different from his.

"I am better than you. I sneaked into a local small enterprise shelter."

"There is a separate bedroom."

"As long as you can fit in, you can take anything."

"It's just that you need money everywhere, and the water and electricity bills are terribly expensive. The salary paid by the company is not enough, and you need to barter for other things."

"I don't know how long I can last."

The person who said this was an ordinary white-collar worker who hid in a small enterprise shelter.

From the few photos he posted, we can see that even in the shelter, he has private appliances such as washing machines, refrigerators, and TVs.

The quality of life is obviously a level higher than that of ordinary people in official shelters.

But official shelters are more or less welfare-oriented, and there will be a bottom line no matter how bad the quality of life is. Corporate shelters do not have such concerns, and everything is based on profit first. Not only is the cost of living higher, but in terms of safety, it is not as good as the official ones. Maybe if you encounter a group of thugs, your life may be in danger.

"Boss, your drone is of high quality."

"I released three drones today, but all three of them broke down. We lost contact completely."

Compared with the complaints of ordinary people, many people are more interested in the photos of the outside world sent by Su Wu.

At this time, he can still grasp the first-hand information outside. You don't have to think about it to know that he must be a rich man.

Of course, people who dare to speak out to make connections are not simple. Even if they have drones, ordinary people do not have the authority to release them out of the shelter. Those who can do it at least have a certain status in the shelter.

"You need a drone with better heat dissipation to go out."

The last person's words caught Su Wu's attention.

The high temperature environment outside seems to have begun to affect electronic equipment.

He replied casually and turned to open the three-dimensional map of the shelter. Sure enough, it was found that the engineering team that was digging the third underground floor of the shelter had different degrees of wear and tear.

Especially for the micro-transport vehicles that need to go out frequently, some of the precision components inside have faint signs of overheating and failure.

High temperature environment obviously has a negative impact on these automatic mechanical equipment.

"It seems necessary to add a new cooling system to the engineering team's vehicles."

"And the geothermal generator on the ground must also be moved to the inside of the shelter. Otherwise, if the temperature is too high, something will happen sooner or later."

Trouble is coming.

Su Wu began to think about how to deal with it.

It is not difficult to install a new cooling system. In the information downloaded from the Internet by the primary artificial intelligence, there is a complete set of corresponding design drawings.

Throw it to the engineering robot and it will be done quickly.

The difficulty lies in the huge amount of energy consumed by the new cooling system. The battery on the micro transport vehicle needs to be recharged every time it is not used for a long time.

"If you want to solve this problem."

"You can use the wireless charging function of the high-energy battery pack."

"You only need to add an additional power receiving device to each device of the engineering team for docking."

After thinking hard for a while, Su Wu found a solution.

The wireless charging technology in this world is quite mature. Although it is not as exaggerated as the wireless transmission of a radius of 100 meters of the high-energy battery pack upgraded in the survival point. But the principles of the two are basically the same. There is nothing wrong with using it only to make the terminal power receiving device.

Solved the hidden danger of the engineering team.

Thinking that there was no other urgent matter to do for the time being, Su Wu began to enlarge the three-dimensional map of the shelter, intending to take advantage of his free time to check and fill in the gaps in its macro design.

A shelter with survival as its main purpose.

The most basic needs are water, air and safety.

In terms of water, the shelter has established a complete set of water supply processes from water source, filtration and purification, storage to transmission.

But water supply alone is not enough. It is also necessary to add corresponding drainage, sewage treatment, and water quality monitoring to form a complete water circulation system.

This requires the establishment of an independent drainage pipeline and multiple subdivided sewage treatment pools.

It is used to strictly distinguish and filter and purify domestic sewage, industrial sewage and laboratory sewage that may be generated in the future.

At the same time, corresponding electronic equipment should be installed at every stage from water supply to drainage for regular scanning and testing of water quality.

Avoid unknown viruses and radioactive substances from the outside world from penetrating the filtration and purification system and sneaking in.

In terms of air, the shelter has installed upgraded air purifiers.

Theoretically, there is no problem.

But the air purifier is, after all, a passive device installed at the vent of the shelter. The reaction has a certain delay.

If an unexpected situation occurs, such as the outer wall of the shelter cracks somewhere, and toxic and radioactive substances from the outside world pour in.

Then before the air purifier is processed, it is likely that the shelter has already suffered irreparable huge losses.

At this time, a set of early warning equipment that can more sensitively monitor abnormal components in the air and respond in time, such as closing the passages around the abnormal air area, is needed as the last insurance.

As for safety.

It solves the hidden dangers of water and air.

The biggest threat left in the shelter is fire.

This is relatively simple.

Whether it is fire source detection or automatic fire extinguishing. There are many mature response plans in the database downloaded from the Internet.

Su Wu doesn't even need to spend extra survival points to upgrade.
