Doomsday disaster: Start by building a shelter

More than 300 tons of steel.

For Su Wu now, it is not something that can be easily obtained.

It would take at least ten days for a small high-temperature furnace to be turned on 24 hours a day to smelt more than 300 tons of steel.

It can be easily obtained by just sending a person to an official shelter once.

There is no reason to refuse.

The task of subsequent communication with the other party was remotely transferred to Chen Xin, who was accompanying her sister in the bedroom.

Su Wu thought about it and realized that he should have nothing to do in the short term.

Then I opened the diary again and began to plan the next development focus.

Currently in Su Wu's hands.

It has an mining cluster with excavators as the main force.

After this group completes the construction of roads leading to small limestone mines, they will be transferred there to become a mining team for open-pit limestone mining.

And then, due to cost and production space considerations.

Equipment related to cement production will also be shipped there. A miniature cement factory was built on site.

This is actually equivalent to opening a new stronghold and production base directly there.

And everything involves production.

Energy is the most critical issue that cannot be avoided.

Both the operation of the mining cluster and the production of cement itself require large amounts of electricity and even coal supplies.

Relying solely on an electric transport vehicle.

It is certainly not enough to maintain the uninterrupted operation of various equipment in the mine.

"After the manufacturing is completed and the related equipment for producing cement is completed."

"Just build another electric transport vehicle and make do with it first."

For the initial development of small-scale limestone mines, it is enough to temporarily provide power from the thermal generator of Lime Sanctuary.

It’s not too far away anyway.

With two electric transport vehicles used alternately, there will basically be no problem of insufficient power.

But wait until later, when the cement plant there is built.

It would be a bit troublesome to make do with it anymore.

Su Wu needs to think about it.

At that time, whether to install two geothermal generators on site, or to transport a thermal generator from the Lime Shelter.

This was a choice that made him hesitate.

Think about safety.

After all, a small limestone mine is a simple and temporary stronghold that mainly mines open-pit ore.

There are not many proven reserves.

Once the ore is subsequently mined, it basically no longer has any value.

So at the beginning of construction.

It would be impossible to build it as a permanent, standard underground shelter.

At most, you can build a basement and a small above-ground bunker, or a sentry tower.

in this case.

If a geothermal generator is built there by force.

The manufacturing and installation costs are huge.

Not only does manufacturing a geothermal generator itself require 10 survival points, but during installation, pulling the extreme drilling machine over and using nanomaterials to lay a steam channel underground also requires a material cost of nearly 2 survival points.

Su Wu must face very heavy cost pressure and a long payback cycle.

In essence, this choice is a huge gamble.

If a thermal generator is used.

The advantage is that the thermal generator itself is not too difficult to manufacture.

Su Wu's CNC machine tools and 3D printers can perfectly manufacture it.

In this way, once damage occurs, it will not be a traumatic event for Su Wu.

But the thermal generator itself requires a large amount of coal or diesel to generate electricity.

Every day it operates, it consumes a large amount of its limited fuel stock.

Essentially exchanging fuel for electricity.

And fuel, or specifically coal.

It was easy to say before.

Now a cement production line is about to be built, and then Su Wu discovered that a large amount of coal needs to be used in the cement production process.

Even with the thermal coal inventory of more than 10,000 tons at Lime Shelter.

In the face of this level of demand, it seems likely that it will not be enough.

Using coal as a fuel for power generation is quite extravagant and wasteful in Su Wu's eyes.

After hesitating for a while.

After all, Su Wu could not resist the temptation of getting free electricity income every day and chose the plan to build two geothermal generators there.

"Let's gamble a little."

"As long as we survive the early stage and recover the cost, we will be able to make a profit later on."

Once a geothermal generator is built, the benefits are permanent.

Although under the threat of natural disasters, there is still a question mark as to how long this eternity will last. But it’s worth looking forward to in the end.

Even if it is indeed very expensive for Su Wu now.

10 survival points are equivalent to a universal engineering robot.

Su Wu has only built three engineering robots so far.

And at the same time.

Now that you have this choice.

Then we must pay more attention to the safety issues of small limestone mines.

The geothermal generator must be installed in the basement under the small bunker.

to ensure resistance to most conventional harsh environments.

The bunker must also be equipped with certain weapons to drive away some human robbers who may wander over.

Don't look at how bad the environment outside is now.

But as long as you wear protective clothing and drive a vehicle, you can still move around in the outside world.

Then there will never be a shortage of such people.

Then, we need to set up enough early warning monitoring networks near the mine.

And reserve an emergency evacuation plan.

Once an irresistible disaster may sweep over. Then try to dismantle the geothermal generator as quickly as possible and withdraw it to the farmyard ruins.

"Everything else can be abandoned."

"But the geothermal generator."

"If it can be rescued, try to rescue it."

This is Su Wu's expectation for the final emergency evacuation plan.

The development route of the small limestone mine has been determined.

Su Wu turned his head and looked at the list of things to be manufactured in the manufacturing center.

In addition to the two transport vehicles currently being manufactured.

Ranked second is a series of related equipment for cement production, followed by electric transport vehicles, the remaining unmanufactured vehicles in the transport cluster, and the two geothermal generators at the sentry tower base.

The tasks are fully scheduled.

Enough to keep the manufacturing center running at full capacity for three to five days.

After Su Wu thought about it.

Move the manufacturing plan at No. 4 to the end.

Then increase the number of geothermal generators manufactured from two to four.

Anyway.

One existing Type 1 ore transporter plus two new transporters, although the number does not reach the full capacity of the transport cluster.

But it is not unusable, at most it can run a few more times back and forth.

Once the geothermal generator is built, it will bring a steady stream of income.

Under the premise that the determination to build has been made, of course, the faster it is built, the better.
