Doomsday disaster: Start by building a shelter

Without the pressure of time.

Su Wu's mental state was visibly relaxed.

He sat in front of the console and moved the mouse casually. As if he was operating a game, he assigned the construction robots.

The number of construction robots guarding the materials in the surface urban area was finally determined by Su Wu to be four.

In order to make up for the lack of guards, more than one K2 series agricultural drone was left. When the next large truck comes to pick up the goods, four more folding shooting platforms will be brought and arranged around.

As for the remaining six construction robots. Four of them will return to the shelter directly with the vehicle to participate in the construction of the last third floor and the capping of the small bunker. The other two will be stationed in the truck cab and responsible for the safety of the large truck during transportation.

If everything goes well.

These hundreds of tons of steel and fertilizers will be transported back to Su Wu's shelter in the next 24 hours.

And in the shelter.

With the completion of the small bunker, the materials piled up on the surface with nowhere to go will also have a place to be stored, and there is no need to fear the storm.

"Then there is the 4th underground floor of the shelter."

"It will be excavated soon."

"Tomorrow, perhaps the level of the shelter can be upgraded to another level."

Su Wu's eyes were full of expectations.

Even in the busiest period, he left at least two construction robots for the engineering team to use for underground excavation. And such persistence has now brought rich rewards.

Returned to the bedroom for a short nap.

Afternoon.

The urban cleanup work came to an end. Su Wu's shelter ranked first among all shelters with a total contribution value of 27,000, and won the first prize of an additional 20,000 contribution value.

According to official regulations, the procedures for collecting and exchanging contribution points are a little complicated.

You need to go to the core No. 1 shelter in Jianghe City, that is, the municipal shelter, to handle it on site.

But compared to what is about to be in hand, this trouble is nothing.

After driving a construction robot to ride a large truck and arrived at the municipal shelter.

Su Wu got a special exchangeable list.

The reward for the first place in the cleanup mission is not only the 20,000 contribution points on the surface, but also an invisible right, which is to have priority in choosing from the official special goods list.

Considering that the number of many items on the special goods list is extremely limited. The actual value of this priority selection right is actually far greater than the simple contribution value reward.

It didn't take too long to choose from the list.

Su Wu quickly locked on some items he needed, and those were also things that had never appeared in the shopping mall provided by the official last time.

In total, there are a batch of rare chemical products and special alloys on the market, an industrial-grade radar, a courier-grade drone, and 20 automotive-grade smart chips.

These things have used up Su Wu's total contribution value of 47,000.

There is nothing much to say about chemical products, they are just used as additives and catalysts to make rockets fly more smoothly.

Special alloys are used to manufacture core parts of some mechanical equipment.

Industrial-grade radars and courier-grade drones are mainly used as references to facilitate reverse research and imitation.

Most of the items that Su Wu upgraded with survival points have extremely high technological content. Even if you want to disassemble and study, you can't start for the time being.

And these devices purchased from the official, with the help of artificial intelligence analysis, are much easier to copy. And after they are made, they can also be used for a lot of purposes.

As for the automotive-grade smart chip.

Just as its name suggests, it will be used by Su Wu to manufacture various vehicles.

If ranked by manufacturing difficulty.

To make an electric-driven vehicle, the most difficult one is undoubtedly the nano-scale chip, followed by the battery and motor.

Batteries and motors are easy to say. After establishing the corresponding 3D printer and material laboratory, Su Wu has great hope to manufacture them independently.

But nano-scale chips are something that 3D printers can't do.

There is no need to hope for self-production in the short term.

If nothing unexpected happens, chips will be a major consumer of survival points for a long time in the future, and they are also the main commodities that Su Wu needs to purchase from outside for a long time.

"Are you sure you want these things?"

The person in charge of receiving the contribution value exchange matters in the official shelter is a young man with a bookish atmosphere.

He looked at the construction robot operated by Su Wu for several times, and couldn't help but confirm with him again.

"That's all, is there a problem?"

Su Wu asked back.

"Of course there is no problem."

"It's just that I didn't expect your shelter technology to be so powerful. These things are not useful to ordinary people."

The young man looked like he had learned something.

In general, shelters must give priority to exchanging medicines and high-calorie and durable food. At the very least, they will also be some basic living supplies.

And the things that Su Wu exchanged, except for express-level drones, other things, without certain technical strength and industrial production capacity, are not as useful as a piece of wood. At least, wood can be used for cooking.

After receiving the things exchanged with contribution points.

Next, the main task of the large trucks is to move the steel and fertilizers stranded in the urban area.

After two special transport vehicles also joined the transportation.

This remaining transportation task took only about three hours before it was completed.

At the same time, at this time.

The construction robots in Su Wu's shelter had gradually transferred all the materials piled on the surface into the small bunker where even the cement on the third floor had not yet completely solidified.

Only a pile of construction waste from the city was left in the original place.

These construction wastes were too large and of low value, so there was no need to store them specially. Even if they were all lost by accident, it would only take a large truck to make a few more trips to the city and bring some back.

"Finally, the work is done."

Watching the large truck on the screen transporting the last truck of steel back. Su Wu completely shook off the last bit of pressure in his heart.

He looked at the time again and found that it was still early.

Su Wu's mind became active again.

He pulled out an engineering robot and two construction robots, let them take two special transport vehicles, and drove towards a hilly area three or four kilometers away from the shelter.

During the period of transferring supplies, Su Wu did not sit in front of the control console and do nothing.

He took advantage of the interval when the wind in the air weakened and controlled the reconnaissance drone formation to patrol around the shelter in circles.

Finally, deep in the hilly area, he found a signal tower that was blown down by the wind.
