Global Collapse: Infinite Upgrade Shelters

"Upgrade first."

Su Ze put his right hand on the wooden floor.

Upgrade target confirmed: shelter air chamber wooden floor.

Upgrade direction: shelter air chamber iron floor.

Upgrade points: 1200.

Warmth rose in his right hand.

The entire wooden floor was upgraded to the iron floor.

The decoration package was completed.

The robot began to move various equipment into it and began to install it in an orderly manner.

After a while, the extremely complex air chamber system was completely installed.

""Not bad. Not bad." Su Ze clapped his hands happily.

He had just watched the installation of various equipment.

It was so professional.

There was no unnecessary movement.

Each equipment was in its place.

It looked like a mechanical work of art.

It was pleasing to the eye.

"Butler, this means that even if the air outside is seriously polluted, the inside can still be self-sufficient?"

"Yes, Master, the air chamber has been connected to the planting area, and all the oxygen produced by the plants will be transported to the air chamber."

"Try it now"

""Yes, Master."

The housekeeper opened the planting area for nourishment.

Su Ze soon smelled a stream of oxygen that penetrated his heart and lungs.

It felt a bit like returning to the woods.

"Butler, is it okay for the shelter to remain in this mode?"

"Master, there is no problem."

The oxygen inside the shelter is self-sufficient!

"Master, the small shelter has been built."

"Let's go."

Su Ze came to the internal elevator and went down to the fourth floor of the shelter, a small room next to the power generation room.

The room was not big, and it was all wrapped in wooden boards.

According to the plan, this is a small internal shelter.

This is just in case.

Once the internal shelter is seriously damaged and survival cannot be guaranteed, this place can maintain space for about 30 days.

As usual.

First, a wave of iron plate layer upgrades.

Upgrade target confirmed: small shelter wooden board layer in the shelter.

Upgrade direction: small shelter iron board layer in the shelter.

Upgrade points: 450 points.

Warmth rose in the right hand.

The wooden board layer of the entire small shelter was upgraded to the iron board layer.

Full sense of security

"Since it is a shelter, then upgrade it to a steel house first."

First, to reinforce the small shelter; second, to see how many upgrade points are needed for the steel house; upgrading directly from the wooden floor to the steel floor, which is stronger than the iron floor, requires more upgrade points.

Upgrade target confirmed: small shelter iron floor in the shelter.

Upgrade direction: small shelter steel floor in the shelter.

Upgrade points: 3000 points.

As expected.

It increased by nearly ten times in a flash.

"First upgrade the small shelter to steel plate, and for other rooms, use iron plate for the time being."

If we talk about the sturdiness, steel plate is better.

But at the moment, the upgrade points are not enough to support the upgrade of all the rooms in the shelter to steel plate.

We can only do it step by step.

"The steel plate layer really feels more solid."

Su Ze exhaled.

The housekeeper had done relevant experiments.

Even if the outside experienced the strongest 12-magnitude earthquake, the shelter would be safe and sound.

Not to mention the small shelter wrapped in layers of shelters, the egg in the egg.

The robots that had been prepared long ago began to decorate.

After a simple decoration, the matching supplies were neatly placed in.

There was enough food and clean drinking water for 30 days.

"How about trying it?"

Su Ze put down a folding bed from the side and lay down on it casually.

It was indeed comfortable.

But maybe because the space was too small, it made people feel a little uncomfortable.

This place was of course to prevent any adverse situation.

As for not coming here normally, it was still more comfortable outside because the space was bigger.

"For the door, it would be best to use a small steel door with fingerprint or iris recognition."Su Ze looked at the door.

"Yes, Master."

Next time, I'll try to get a matching steel door.

Su Ze took Xiao Mu and Xiao Li out of the small shelter and returned to the main control room.

The small internal shelter was successfully built.

"Butler, open the shelter design"

"Yes, Master."

The original design of the shelter appeared on the big screen.

According to the design of the shelter, the last two rooms are missing.

One is the weapons and equipment room; the other is his own studio.

"Manager, this studio can be discarded, and the main control room should be the studio."

"Yes, Master."

The studio erased it from the blueprint.

A weapons and equipment room is a must.

Drones, guns and ammunition, protective clothing and other equipment need a special space, and they can't be piled up in the warehouse all the time. In this case, the last equipment room is missing.

In fact, the robot has already started digging, and it will be completed in a while.

""Huh~" Su Ze exhaled.

Now, his ideal shelter is finally about to be completed.

It is really an ideal.

Looking around the world, there are certainly many people whose personal shelters have reached his level.

But the difference is huge.

A shelter like his is already the final level for others.

But for him, it is just the initial level.

With unlimited upgrades, any material in the shelter can be upgraded unlimited times.
