Doomsday disaster: Start by building a shelter

The largest feed planting area.

The various grasses carefully planted there are growing well, and many of them can be harvested.

In the planting area, a small area has been specially cleared.

There are a few lambs with pure fur like white clouds.

This is a precious gift from Chaoyang Shelter.

Because there is a lack of breeding space in the shelter, we can only vacate a small area in the planting area to temporarily place them.

When the fifth floor is completed, we will choose a place for them again.

The second underground floor is where Su Wu lives and does his main activities.

Because he is too familiar with it, there is no need to patrol it carefully.

After scanning the report that the air detection is normal, Su Wu's sight jumped to the first underground floor again.

The hydroponic farm on the first floor is still quiet and bright.

The vegetables, fruits and flowers planted here make this floor full of green vitality.

Every time you see it, you can soothe and relax your spirit.

And in the end of the world.

The era of the extinction of all things.

Any jewelry, as well as all other luxury goods.

None of them are as dazzling and eye-catching as the green in the hydroponic farm.

They are the existence that can be called treasures in the end times.

Beautiful things.

They always make people feel good unconsciously.

After looking around the hydroponic farm. Su Wu's heavy mood brought by the radiation storm was relieved a lot.

He also had an impulse to protect this place.

He had finally built the shelter to its current scale and had such a beautiful home.

How could he give up easily just because of the disaster?

After inspecting the shelter, Su Wu switched to the manufacturing center.

After manufacturing the equipment in the chemical laboratory.

The next manufacturing task here returned to the theme of the past.

Everything is based on the primary purpose of developing and expanding the shelter space.

At present, they are making small excavators and gravel trucks that Su Wu had just designed.

With the current surplus productivity excluding the production of radiation detectors, an average of one small excavator or one gravel truck can be produced every 8 hours.

In Su Wu's plan.

After two small excavators and two gravel trucks are produced respectively.

Then all the miniature series vehicles manufactured earlier by the engineering team, including gravel trucks, excavators and transport vehicles, will be pulled to the manufacturing center for refitting.

Let their size and performance reach or at least approach the level of the new version of engineering vehicles.

And because of these modifications, the smart chips and high-energy batteries inside the vehicles have not been touched.

It will not consume Su Wu's survival points.

In a sense, it is equivalent to a free upgrade.

"The fastest is the day after tomorrow."

"The engineering team can complete the modification and expansion of this stage."

"By then, the speed of the engineering team's excavation of underground space will continue to increase by two to three times on the current basis."

"It is also about 15 times the efficiency of the engineering team before obtaining CNC machine tools and 3D printers."

What does a 15-fold efficiency gap mean?

Before the emergence of CNC machine tools.

It took the engineering team 12 days to dig out a standard space of 600 square meters.

If the efficiency is increased 15 times on this basis, a new layer can be added to the shelter in less than a day.

Even considering the current underground 5th floor.

The internal floor height reaches 12 meters, which is twice that of the previous floors. The design area has also expanded to 3,000 square meters.

The new engineering team can also open it up from scratch within 8 days.

At that time.

What limits the expansion speed of the shelter is no longer the construction capacity of the engineering team, but the supply of raw materials. More precisely, it is the supply of cement.

"It is probably difficult to meet the demand for building shelters by relying solely on transactions."

"It is time to consider mining limestone mines."

"Self-produce cement."

Su Wu thought of the small limestone mine he found deep in the mountains when he was laying the monitoring network.

At that time, it was believed that there was no road there, it was difficult to enter and exit, and it was extremely difficult to mine.

It needs to be temporarily shelved.

But now.

Facing the huge gap in cement demand in the future, it is difficult to do it.

If it doesn't work, even if it is transported by drone.

The mined ore must also be transported back bit by bit.

Of course, it doesn't have to go that far in reality.

Pull up a map of the mountain area taken by a recent drone.

Su Wu began to carefully study the route to the limestone mine.

The 6 kilometers before entering the mountain area are the simplest. Just follow the original road.

Then there are many mountain roads in the outer area of ​​the mountain range.

Those mountain roads have been widened by many people who built shelters in the mountains. Until now, after the wildfires, most of them are still barely usable.

Su Wu patiently searched among them. Soon he pieced together a mountain route with a total distance of about 7 kilometers.

And at the end of this route.

There is no road at a straight-line distance of 3.7 kilometers from the small limestone mine that was discovered.

There are only steep cliffs and rift valleys.

"This place."

"It's not easy to go up or down."

Su Wu fell into deep contemplation.

Finally, he set his sights on the belly of the mountain.

If there is no road on the cliff, then carve one out. It doesn't need to be too high or too wide, as long as it allows a type 1 ore transport vehicle to travel in one direction.

Even if you want to go faster, you don't even need to carve out a complete road.

You can build a suspended plank road.

The required supports can be made of ready-made steel bars and angle irons. And the road surface does not need to be made of too good materials. You can just dig some iron sheets from scrap metal.

If the materials are not enough.

In the past two days, a batch of finished steel materials have been transported from other large shelters.

They can all be put in.

Anyway, after the small limestone mine is mined, these steel materials can be recycled.

At most, some electricity will be lost in the middle due to re-smelting.

Then for the canyon.

It should be no problem to build a suspension bridge with drones and steel-woven ropes.

It's still OK as long as it can be used.

The whole road construction plan is not complicated to say.

However, the actual implementation will require a lot of resources and manpower.

Perhaps the noise will be a bit loud.

However, Su Wu no longer needs to hide. He is capable of supporting this operation.

There is no need to worry that after the small limestone mine is mined, others will reap the fruits.

"It's decided."

"Wait until the engineering team is expanded."

"Start to create such a team to open mountains and build bridges."
