Doomsday disaster: Start by building a shelter

[Current territory: livable personal shelter (55%), daily fixed survival points +3. ]

[Current remaining survival points: 45. ]

A new day.

Looking at the experience bar behind the shelter level, which has been advanced to halfway.

Su Wu is in a very good mood.

At this rate, it won't take long for the shelter to be upgraded to the next level.

By then, let alone opening new system functions. At least, the daily fixed survival point income will definitely increase a bit.

Life will get better and better with the naked eye.

After washing up.

Holding a piece of soft and toasted bread, Su Wu came to the control center's operating table as usual and conducted routine inspections of the shelter and its surroundings.

The whole night passed.

There was almost no change inside the shelter.

Only the engineering team was still on the fourth floor underground, constantly digging and excavating. Continuously expanding the space of the shelter.

Outside the shelter, there was unexpectedly a little movement.

Except for the occasional large trucks that transported goods back and forth. A group of unknown birds passed by in the sky, and one or two small animals appeared in the rocky beach in the distance.

"Under such high temperatures, the animals on the surface have not been completely extinct."

"Really tenacious."

Su Wu was a little surprised. This may be the so-called life will find a way out. Not only humans, but other animals are also struggling to survive in extreme environments.

After checking the log, it was determined that the environment around the shelter was temporarily safe.

Su Wu began to look through the list of material consumption in the shelter.

It was found that the most frequently used materials for building shelters, stones and construction waste, that is, concrete blocks, were almost exhausted.

"It seems that a special team for mining outside should be established."

Su Wu pondered.

Although stones are everywhere outside the farmyard. But most of them are strange and large. In addition, most of them are buried deep in the soil. It is not an easy task to dig them out.

As for construction waste, it is even harder to say.

According to the information Su Wu had, he had to go to an abandoned village two kilometers away and dismantle the houses himself to get enough construction waste.

Once such a long distance was reached, the risk was at least two orders of magnitude higher than that of construction in a farmyard. It was not suitable for the precious engineering team to work part-time.

Opening the design software skillfully.

Su Wu began to think about how to build such a team dedicated to excavating and transporting construction materials.

First of all, according to convention, its scale could not be too large.

The engineering team used to expand the shelter only had a few micro vehicles and construction equipment. As one of the accessories that provided them with raw materials, it was even less likely to be large.

And if we consider the limitation of scale.

In fact, there is no need to manufacture separate units for excavators, electric pickaxes required for demolishing houses and handling overly large stones.

They can be integrated into the same transport vehicle to save manufacturing costs.

The only disadvantage is that this will reduce some collection efficiency.

However, this shortcoming can be basically ignored in the face of the mechanical unit that can work continuously for 24 hours.

Under long working hours, even the lowest work efficiency can accumulate enough considerable results.

Marking on the design drawing.

Soon, a complete excavation and transportation team was streamlined by Su Wu himself into a lonely special transport vehicle.

The appearance of this special transport vehicle is somewhat similar to a mini transport vehicle.

There is no cab, only a tracked chassis similar to a tank and an open truck bed. At the same time, there is a metal cabin at the rear of the vehicle that is only one-fifth the size of the truck bed. It is equipped with electric picks, mechanical arm buckets and other electric tools, which can be used to work by themselves after arriving at the destination.

Considering the need to work long distances, increasing the carrying capacity can significantly improve the overall efficiency, but the cost will not increase too much.

The size of the special transport vehicle is a whole circle larger than the mini transport vehicle. The length of the whole vehicle is close to five meters, which is not much different from that of an ordinary family car. At the same time, the load capacity is the same as that of a large truck, also reaching 20 tons.

"One vehicle is a mining and transportation team."

"This deserves the prefix of special."

Looking at the design drawings he drew by himself, Su Wu showed a satisfied expression.

More importantly, at the same time as the drawings came out.

Artificial intelligence simultaneously listed the specific manufacturing plan and the list of materials required.

With the help of engineering robots and some raw materials traded from official shelters, 97% of the spare parts of special transport vehicles can be self-produced, and the total production time does not exceed ten hours.

Such a high degree of completion means that Su Wu will probably only need five to six survival points to get a finished special transport vehicle.

Compared to the initial manufacturing of micro transport vehicles and micro excavators, the cost has been significantly reduced.

No delay.

After the design drawing was completed, Su Wu added it to the manufacturing center's waiting list.

Finished this necessary work.

Su Wu did not leave the control center.

On the console, he switched the large screen to another interface. Pressed the start button.

Eight or nine seconds later.

A concrete floor and a gray sky appeared on the screen.

This is the perspective from the drone.

During the period of transporting the official shelter materials from the transaction, Su Wu was not idle. Relying on the abundant materials in his hands, he made a certain degree of transformation inside and outside the shelter. One of the most important changes was the construction of a vertical passage connecting the inside of the shelter and the roof of the two-story residential building in the farmyard.

This passage is about one meter in diameter, with a lifting platform and multiple explosion-proof isolation doors that can be closed automatically. While ensuring the absolute safety of the shelter itself, all types of drones in the shelter, including the K2 agricultural drone, can be quickly released.

In an emergency, if necessary, this vertical passage can even be transformed into a rocket silo. The rockets in the shelter are directly launched.

[The reconnaissance drone formation is ready. ]

[Normal monitoring of the surrounding environment. ]

[The current real-time temperature is 67.5 degrees. ]

[Start to take off. ]

In a dark and silent world.

Three palm-sized drones, flashing faint lights, slowly took off from the roof of the farmyard. After circling in the air for a few circles, they gradually flew towards the distant mountains.

Su Wu had long been curious about the mountains that had experienced an unprecedented fire.

Now that he had some free time, he naturally wanted to explore it.
