Doomsday disaster: Start by building a shelter

Early morning.

Farmyard, the outer area of ​​the 8th underground floor.

In the factory, the continuous metal machines gradually light up the green indicator lights representing operation.

Then, along with the brand new conveyor belt, the first sound of rotation sounded.

Boxes of hard concrete blocks began to be sent to the large crusher to be ground into powder.

Then they were transferred to a billiard-shaped reaction device.

Half an hour later.

The first batch of fast cement, with a faint residual temperature, poured down from the exit at the end of the production line.

Gradually piled into a small hill.

A transport vehicle that had been waiting there for a long time shoveled it into the cargo compartment.

It slowly drove away until it was full.

It will go to the 7th underground floor, which is about to be completed, so that the construction robot there can use fast cement to cast the exterior wall.

At the same time, also waiting there, a miniature shield machine with a diameter of 0.6 meters, which was transformed by the engineering robot overnight from a gravel truck.

It will also carry some of the fast cement brought by the transport vehicle.

Starting from the 7th floor.

Officially began to dig the material transportation channel.

This material transportation channel will connect the nearest green lemon shelter.

At the same time, for a long period of time in the future.

It will also be the only route for the farmyard shelter to exchange materials with all other affiliated shelters in the outside world.

However, don’t look at this material channel. The overall height and width are only 0.6 meters, which is as small as playing house.

But according to the specifications of the small train designed by Su Wu for transporting materials.

A train can haul 5 cubic meters of materials through the channel at a speed of 20 kilometers per hour.

If a few more are made and put into operation in the material channel at the same time.

If the frequency of one train every three minutes is guaranteed.

In a day, a total of 2,400 cubic meters of materials can be transported back and forth.

If all the transportation is basic materials such as steel, it will be nearly 20,000 tons.

And the frequency of one train every three minutes is actually a bit low.

Under the precise control of artificial intelligence.

There is no big problem in achieving one trip per minute, or even one trip per 30 seconds.

But that's it.

For the shelter as the terminal, there will also be quite high requirements.

A huge space that can allow dozens or hundreds of small trains to stay at the same time must be reserved.

After all, this is just a one-way transportation channel and cannot form a cycle.

There must be a gap in the middle when turning.

But for now.

There is no need for such a high transportation efficiency for the time being.

More than 2,000 cubic meters of material transportation quota per day.

It is enough to use.

While the farmyard shelter located underground is busy working.

On the surface.

Under the heavy rain.

Thousands of drones equipped with disinfection lamps are still cruising at a constant speed in every corner of the city ruins and floods.

Continuously killing the Rora virus on the surface.

After their efforts these days.

The virus hidden within a radius of dozens of kilometers around Jianghe City has been significantly reduced.

The threat to the surrounding shelters of all sizes has been reduced sharply.

At least it will no longer be the case that a small number of raindrops and water vapor falling into the ventilation ducts can easily infect a large number of people as in the beginning.

And then with the gradual popularization of disinfection lamps inside various shelters.

At present, the number of newly infected people per day has been reduced to less than one thousand again.

The entire Jianghe City has gradually shown a trend of walking out of the shadow of the Rora virus.

Under the drone group.

In the raging flood.

Some spider robots and humanoid service robots began to drive unstable kayaks again.

The last part, hundreds of thousands of tons of materials abandoned in the underwater shelter, were salvaged bit by bit.

Then they were transferred to an unmanned small shelter specially vacated by Su Wu for storing materials.

The larger 30 medium-sized hovercrafts.

Still like passenger ships, they continue to travel between various large, medium and small shelters.

With the completion of the construction of the fast cement production line manufactured by the queue jumper.

The manufacturing center once again tilted most of its productivity to the production of capsule grids.

After having enough places to accommodate them.

These medium-sized hovercrafts also resumed full speed.

Each time, thousands of seriously infected people will be transported to the Jiewei Shelter.

Accompanied by their continuous transportation.

It is expected that by the end of today.

The Jiewei Shelter, a medium-sized shelter with a maximum design capacity of only 10,000 people.

Will gather more than 630,000 seriously infected people.

Officially surpassing the Jingyuan Shelter.

Becoming Su Wu's, and all the civilian shelters in Jianghe City.

The largest shelter in terms of population.

Outside the urban area of ​​Jianghe City.

On the other side of the seemingly endless waters formed by the flood.

Deep in the mountains.

Small limestone mines and iron mines belonging to Su Wu.

Not affected by the virus at all.

A large number of engineering machinery.

There maintained the same rhythm as before.

Producing cement and iron ore at the highest speed.

Then one ore transport truck.

Along the recently opened mountain road.

Transport them down the mountain.

of these products.

The cement will be transported to several inhabited auxiliary shelters according to a certain proportion.

For them to build standard dormitories inside the shelter.

Although Su Wu now has better fast cement.

But considering the limited raw materials.

In this kind of unimportant internal construction, it is still more preferable to use ordinary cement first.

As for the excavated iron ore.

Priority will be given to the Jingyuan Shelter for supply to the thin iron sheet production line there.

The remaining part is unusable.

It will then be distributed to the Green Sanctuary and Watchtower Base.

The finished steel is slowly smelted through the original small high-temperature furnace there.

Other than that.

Dozens of transport vehicles have played a major role in rescuing survivors in underwater shelters.

Along with more than a dozen excavators that have been waterproofed.

A new scavenging cluster was formed.

Started picking up the trash again.

But this time.

They do not specifically select various scrap metals buried deep in construction waste.

Just on the edge of the city near the farmhouse.

Place the concrete block inside there.

Load the truck and pull it to the surface of the farmyard.

These concrete blocks serve as the main raw material for the production of rapid cement.

It will be crushed and disinfected in the production factory on the 8th floor underground of the shelter.

Put it into the reaction tank for making quick cement.

Then the limestone contained in it will eventually be turned into the finished product of rapid cement.

The remaining separated sand and gravel will become garbage.

Transported to the surface again and thrown away.
