Doomsday disaster: Start by building a shelter

The three optional upgrade directions in a row made Su Wu's eyes brighten.

Needless to say, the diesel version is probably similar to the ordinary mini excavators on the market, but it is not cheap.

All it takes is two survival points and used items worth thousands of dollars at most. You can get a brand new mini excavator with a current market price of more than one million. If used well, this is a ladder that can allow Su Wu to become a rich man.

The only pity is that in the context of the coming apocalypse. The so-called rich people are not that attractive in terms of gold content.

"There's no rush."

“Currency has almost become a coupon now, and it’s useless to ask for more.”

"It's bartering. The value is there anyway, so you can exchange it anytime."

Su Wu restrained his impulse and turned his attention to the other two options.

Compared to the diesel version. The battery version and the unmanned version are more in line with his current needs.

He couldn't get any extra diesel. But after putting a geothermal generator into operation, there is no possibility of shortage of electric energy.

As for the unmanned version, it is actually a comprehensive feature package. Including battery power, as well as unmanned and autonomous construction.

Among them are unmanned and autonomous construction.

It is also very important for Su Wu.

After all, Su Wu was the only one.

At the same time, due to cost and confidentiality considerations, workers cannot be hired to dig underground shelters.

The emergence of the unmanned version solved his urgent need.

"Upgrade the unmanned version."

Su Wu didn't hesitate too much. The full 29 survival points he gained yesterday gave him a lot of confidence and the ability to be a little extravagant.

After an instant upgrade.

A mini excavator with no driver's seat, a track and chassis length of no more than 1.5 meters, and a sci-fi appearance appeared in front of Su Wu.

Su Wu took a closer look. Discovered that his laptop could wirelessly link to the mini excavator’s on-board computer. Then through the laptop, you can directly give instructions to the mini excavator remotely and arrange work tasks.

"Total weight 1.5 tons."

"At full power, it consumes two kilowatt hours of electricity per hour."

"The car battery has a capacity of 40 degrees Celsius and a maximum charging time of 2 hours."

"The data are pretty good. Compared with the products on the market, it should be considered that it has been upgraded for at least half a generation."

There was no rush to start the mini excavator.

Su Wu first checked its basic data through the prompts of the apocalyptic survival system.

It was found that both the battery capacity and charging speed are more than twice that of batteries of the same specifications on the market.

This is not an amazing piece of black technology. But the technical level is enough to be rated as advanced, barely worthy of the upgrade cost that is three times that of the diesel version.

If the social environment is stable. Just through reverse research on this car battery, you may be able to become a regional rich man.

pity--

After tinkering for a while, I satisfied my curiosity. Su Wu ran back to the bedroom and connected the mini excavator with his laptop.

Then he called up the design drawings of the shelter that he found on the second-hand market.

Transmitted to the on-board computer of the mini excavator.

After more than ten seconds of data matching.

The on-board computer sends back a successful matching prompt.

Then the mini excavator located in the yard started to start the engine and excavate the soil on the ground according to the plan on the design drawing.

And at the same time.

On Su Wu's laptop screen, a virtual underground shelter structure diagram was displayed.

It also includes the outline of the farmhouse on the surface, the geological conditions underground, the location of the excavator, etc.

Even the stage of the project and the estimated remaining excavation time are clearly marked.

Both detailed and clear.

"This level of automation is so strong."

I found that I didn't seem to have much room to intervene.

For a moment, Su Wu had the illusion that he was playing a game.

He turned his head and looked down at the mini excavator through the bedroom window, slowly digging a downward slope on the flat ground in the yard. After a while, he came back to his senses.

Now is not the time to waste time.

Get up and walk downstairs to the yard.

Su Wu walked around the place where the mini excavator was working.

Mark out the location.

He picked up an electric hammer and smashed it towards the courtyard wall.

The small farmhouse where he lives is located in the suburbs. The main entrance of the yard is adjacent to the highway, and behind it is a deserted rocky beach.

The area occupied is neither large nor small.

If you go out from the main entrance, go around to the rocky beach at the back. It takes quite a long journey.

to this end.

Su Wu planned to re-open an exit on a wall near the rocky beach at the back for future transport trucks to pass when dumping earth and rocks.

This is one of the few places where he can help in the process of building a shelter.

But it was well planned.

In actual implementation, there is a slight deviation.

This seemingly simple task is extremely demanding on physical strength.

When Su Wu was out of breath, he reluctantly smashed a gap two to three meters wide in the courtyard wall. It was already three hours later. By this time. Su Wu was so tired that he almost didn't have the strength to lift the electric hammer.

"Never do this again next time."

Su Wu felt a little regretful, having underestimated the intensity of labor beforehand.

He leaned against the wall and rested for a while. I wiped my sweat and drank a can of Coke to rehydrate. Then I simply tidied up the ground.

Returned to the yard.

The engineering robots in the hospital are almost finished building the micro transport vehicle.

Su Wu simply waited there. As soon as the engineering robot was completed, five survival points were spent to upgrade it.

Upgraded micro transporter.

It looks like a large toy.

The entire vehicle is less than two meters long.

Because it is driverless. There is no cockpit on it, it is just composed of a crawler chassis and a truck body that can carry up to two or three cubic meters of earth and stone.

[Maximum driving speed: 20 kilometers per hour. 】

[Load-bearing capacity: 5 tons. 】

[Car battery capacity: 40 degrees. 】

[Maximum continuous operation: 40 hours. 】

As a transport vehicle. Its speed is pitifully low, somewhere between a tool and a large toy.

However, Su Wu was quite satisfied with this.

He specially arranged for engineering robots to make the crawler chassis, and he did not pursue speed. As long as it can drive smoothly on muddy ground and piles of rocks, it can complete the work of transporting earth and rocks over short distances. That's enough.

As for the load. Perhaps it is because the crawler chassis is relatively strong and the engine power is sufficient.

Its load-bearing limit reaches 5 tons.

Even if the body of the truck is filled with rocks, it can still drive normally without any stress.

As far as the project of building a shelter is concerned, there are almost no shortcomings in this transport vehicle.

No hesitation.

Su Wu quickly incorporated this freshly made transport vehicle into the engineering team.

immediately.

Accompanied by the sound of rotating metal bearings on the micro-transporter.

It began to drive slowly toward the construction site. With the help of a mini excavator, the soil and gravel that had already accumulated into hills in the yard were transported and dumped to the gravel beach outside the yard.
