Doomsday disaster: Start by building a shelter

Looking at all the raw materials used to prepare radiation-proof coatings, they are quite common.

Even if you purchase special phosphor powder from the official, the unit price is not too high.

But this cannot withstand the ridiculously huge loss and purification during the production process.

"No wonder the finished products sold by the official are priced as high as 22,000 contribution value per liter."

"It's not that they are too shady, it's just the cost."

"This aspect is more conscientious than selling experimental equipment."

Su Wu realized at this time that the price of the finished radiation-proof paint sold by the government was really not meant to deceive them.

With a price tag that is only 10% higher than the cost, it is still a nearly monopoly-level product that is in demand. Even before the end of the world, it can be said to be cheap.

Shaking his head, Su Wu summoned a construction robot.

Let it take the newly prepared radiation-proof paint to the manufacturing center.

Since paint is precious, you can only pick up the important ones first.

For automatic equipment such as robots and engineering vehicles, it is enough to modify the core electronic parts and apply a layer of paint to ensure that they can operate normally and will not be affected by radiation.

However, for large trucks, it is basically impossible to save.

Whether it's the cab or the enclosed compartment at the back.

Taking into account the possible demand for manned cargo transportation in the future, it must be filled up no matter what.

"The exterior walls of the shelter itself also need to be painted with a layer of radiation-proof paint."

Su Wu pondered.

Painting the entire shelter with radiation-proof paint is a big project. Just thinking about the total area of ​​​​the shelter's walls can make one's eyes darken.

One liter of anti-radiation paint can cover 10 square meters. I want to paint all the exterior walls of the first four underground floors of the shelter, including the ceiling on the first floor and the floor on the fourth floor.

At least 180 liters of paint with a total value of more than 3.6 million contribution value.

But this is inevitable.

Although the shelter is located underground, the soil, rock formations, and thick concrete walls can provide some protection against radiation.

But if the radiation from the outside is strong enough, it will not reach the standard of a radiation disaster. Even if it is slightly weaker, it is enough to have a certain impact on the interior of the shelter.

The shelter is the home where Su Wu lives on weekdays.

As long as he didn't want to be at home in the future, he would have to carefully avoid radiation-laden places one after another. As long as he still wants to eat the output of normal hydroponic farms and farms.

The expenditure on these anti-radiation coatings cannot be saved at all.

Not only cannot it be saved. Su Wu even planned to use survival points to enhance the radiation resistance on top of applying radiation-proof paint.

But after thinking carefully and carefully.

He suppressed this impulse for the time being.

The lessons from the last storm are still fresh in my mind. No one can be sure that when facing a radiation storm next, only radiation will be the only disaster.

Just in case, if there is another accident, all the survival points will be used up in advance.

Then I'm afraid I won't be able to just stare.

From this aspect.

Only by mastering enough survival points can you have the initiative.

Of course, that being said, it should still be used where it should be used.

for example.

Su Wu looked at the three-dimensional map and paused at the exit passage.

After having the micro-mecha, his own life safety is completely guaranteed. The exit passage of the shelter, which was originally the most important security checkpoint, can also be slightly relaxed at this time.

Daily supplies of the shelter are allowed to enter and exit through this passage.

Since it is necessary to communicate with the outside world, taking into account the radiation problem, a multi-stage clean room is built to eliminate residual radiation using the special structure of the exit channel.

It has also become a necessity.

"In addition, the external door and the internal isolation door of the exit passage must be added with a special lead plate and then coated with radiation-proof paint."

"The door walls on each floor close to the lifting platform also need to be painted."

"Then, the fifth underground layer that is being excavated, the vertical passage that has been opened up separately and specially used to transport construction waste, etc., also needs to be modified."

"Build another one near it to eliminate the radiation residue."

"Well, the drone lifting platform and the multiple isolation doors on the platform channel also need to be painted."

"Then there's the ventilation ducts, the air purification system—"

Su Wu made modifications based on the three-dimensional map of the shelter. Try to strengthen and complete all possible communication points with the outside world.

And after this change.

The workload of engineering robots and construction robots was immediately full.

At least I don't have three to five hours to complete these modification tasks.

"That should be it."

"The raw materials for radiation-proof paint are probably enough."

"There is no need to make additional purchases."

I checked it again and again to make sure there were no omissions in my arrangements.

Su Wu breathed a sigh of relief.

Special phosphor powder needs to be purchased from the official.

Although it is one of the main materials of radiation-proof coatings, it actually only accounts for one-twentieth of the total cost.

Calculated, each liter of radiation-proof paint only requires 1,000 contribution value of phosphor.

Su Wu came down with this modification.

The consumed phosphor may only occupy about half of the inventory currently on hand.

“But next time I purchase from the authorities.”

"You can buy some plants that can extract fluorescent powder."

"In the future, a special area will be carved out for planting on the fifth underground floor or other levels."

“This important resource must be produced entirely by itself to make people feel at ease.”

New planning was completed for the shelter.

Su Wu's part of the work is completed.

Next, he just needs to wait quietly for the radiation storm to come.

At the console, switch the main screen to a ground monitor.

Su Wu looked at the trucks and busy construction vehicles parked on the ruins of the farmhouse that had been bulldozed, waiting to unload.

——Those large shelters took away most of the construction machinery, but in the end a small part remained. It does not affect loading and unloading.

Su Wu has made all preparations.

And these workers are still on the surface.

How many of them can die safely under the influence of the radiation storm?

It's just that these are things that the management of the large shelters they belong to need to consider.

As a vested interest, Su Wu had no direct relationship with those workers.

Even if they know that they will not be too optimistic about the future.

There is no way to take out the precious radiation-proof paint and share it with them.
