Doomsday disaster: Start by building a shelter

“Then the original standard dormitories and various areas for ordinary people’s activities still need to be constructed.”

"Until it reaches a size large enough to accommodate 10 million people."

Su Wu had suffered enough from not having enough space to accommodate the population.

Considering that in the future, there is a high probability that people will continue to be recruited from the outside world.

It has become a matter of course to continue building standard dormitories.

Moreover, for these shelters in Jianghe City, which were built by ordinary engineering teams, the quality varied.

Su Wu actually didn't think highly of it.

These shelters.

Even if it is an official shelter with the highest construction standards and the top ten numbered shelters.

Ordinary concrete is still used.

Randomly encounter an earthquake of magnitude 7 or 8.

You may suffer significant damage.

Judging from the limited external information that Su Wu came into contact with after taking over the official shelter in Jianghe City.

Although the outside world has not seen the kind of super earthquakes before.

But various small-scale earthquakes below magnitude 9.

But it never stopped.

For safety reasons, it is obviously not cost-effective to invest heavily in the development of asset-heavy industries such as industry in these fragile shelters.

Might as well just build some dormitories and plantations.

It is used to temporarily resettle the population and produce food.

In this way, even if there is an accident, the loss will not be too heavy.

And in the future.

Wait until the farmhouse develops to a certain scale and has enough space.

Su Wuhui gradually moved everyone in Jianghe City to the farmyard.

Forming a super shelter that can accommodate millions of people at the same time.

"At that time, the innermost core area will be your own private land."

"The second ring outside is a major grain production area."

"The third ring serves as a scientific research area and a living area for high-level talents."

"The fourth and fifth rings are used as ordinary residential areas."

“The Sixth Ring Road serves as an industrial manufacturing zone.”

"The seventh ring serves as the outer military defense zone."

"A complete super shelter will do the trick."

Su Wu was thinking about the future.

Relying on fast cement, a material belonging to the interstellar age.

Concentrate all population and resources into one shelter.

Can maximize resistance to disasters.

Even if the time comes, it will sink deep into the ground due to the earthquake.

Relying on the huge size of the super shelter itself, it can still continue to survive and develop safely.

At most, it will be more difficult to obtain resources from the outside world.

Daily water supply will come from recycled filtered water inside the shelter.

It may be a little difficult to accept psychologically.

And besides that.

Su Wu opened the panel of the apocalypse system.

Set your sights on the shelter levels above.

[Current territory: Developed medium-sized shelter (7%), daily fixed survival points +5. 】

After Su Wu started the second external expansion construction of the farmhouse.

His shelter level quietly changed from a powerful personal shelter (max) to an open medium-sized shelter (0%).

Rise in level.

The fixed daily survival point income has also been increased from 4 points to 5 points.

Don't look at just a little more.

With the blessing of Su Wu's now more powerful technology and industrial productivity.

It can do much more than it has in the past.

It must be described.

That is, if you start with a few survival points, it is probably equivalent to resources worth hundreds of thousands.

So now, it can exert resources equivalent to tens of millions or even hundreds of millions.

It was a huge income that could not be ignored even in Su Wu's eyes today.

That's why.

Build farmhouse shelters as much as possible.

Let the shelter continue to be upgraded from the current medium to large, or even super large, to obtain more survival point rewards.

It has also become a necessary option for Su Wu's development.

For Su Wu, no matter how well the attached shelter is built.

It's better to take a little step forward by letting your own farmhouse take shelter.

certainly.

This is all a long time coming.

The current farmhouse shelter.

The ongoing second phase, which is the expansion project from a diameter of 100 meters to a diameter of 500 meters, has not even finished digging the first layer at the bottom.

It can only be said that everything has just begun.

afternoon.

Farmhouse courtyard, core area with 6 underground floors.

Simulation test site.

"The 97th vibration test begins."

Proving ground.

Inside a one-meter-thick sealed room made of quick cement.

There was a dull roar.

The violent explosion turned into a shock wave that shook the wall facing the inside of the room.

But in the end it didn't leave any permanent damage.

"very good."

"There was no obvious damage to the main body of the building."

In the control center on the underground floor, Su Wu watched remotely.

Looking at the test report of the sealed room, I felt a long-lost surprise.

Get fast cement so long.

Su Wu still hasn't fully explored all its characteristics.

This time.

Trying to use a special alloy melted from the exoskeleton armor captured from the Yukikaze mercenary group.

After mixing quick cement to form a one-meter-thick interlayer.

Su Wu made an unexpected discovery.

Its strength has been further improved by a near-qualitative change.

It is not a simple quantitative increase from 1-meter-thick concrete to 20-meter-thick concrete.

It is a change in material properties similar to the change from soil to steel.

With the blessing of this new property.

Even if it is simulated based on the intensity of the epicenter of the super earthquake that Jianghe City encountered last time.

It cannot be truly torn apart.

And this means that if Su Wu thickens the outer walls of the shelter to one meter with quick cement.

Then he will no longer have to fear disasters such as earthquakes.

"After deducting the alloy frame and water, one cubic meter of fast cement wall requires exactly one ton of fast cement."

"Calculate it this way."

"Replace the core area of ​​the farmyard shelter with a diameter of 100 meters."

"Replace all with one-meter-thick fast cement exterior walls."

"About 26,000 tons of fast cement are needed."

"That is, the current production of two or three days consumes less than 30 tons of rubber raw materials."

Su Wu quickly calculated in his mind.

It was found that according to this building standard, it was not difficult to promote it in the core area.

Even the second ring area currently under construction.

It also uses one-meter-thick fast cement as the exterior wall.

Each layer only requires less than 20,000 tons of fast cement.

There is no pressure on supply.

And the other raw material, the same alloy as the exoskeleton armor.

It is not difficult for Su Wu.

There is a ready-made physical reference.

It does not require much spiritual power to directly analyze the raw material formula.
