Doomsday disaster: Start by building a shelter

Adhering to the habit of thinking of the worst in everything.

Su Wu almost didn't hesitate for too long, and decided to add a batch of new weapons on the spot.

Considering that he might face more enemies this time.

Simply adding guns or rockets is not cost-effective, and it can't bring overwhelming advantages.

Su Wu searched the database for a long time and finally came up with a brand new plan.

That is to make thermite.

Thermite is a mixture that can produce a high temperature of more than 2500 degrees after burning, which is enough to melt steel in a very short time.

Its main materials are very common and cheap aluminum powder and rust.

But the power is terrible.

No matter how tight the protection is, once it touches the burning thermite, it will eventually be burned through.

The only drawback is that it burns in a very small range.

However, it is not difficult to solve this problem. As long as a small bomb or fireworks are added to the thermite, its lethality can be expanded to a very considerable range.

As for the launch method.

Su Wu chose to use drones to throw directly, and to make artillery shells and launch them from howitzers.

Both options have extremely low costs.

Among them, drones can be replaced by K2 series agricultural drones. Although howitzers have to be built from scratch, their structure is much simpler than intelligent automation equipment such as micro excavators, and at most they have certain requirements for materials.

Engineering robots alone can build them completely. There is no need to use precious survival points at all.

"Wait until the small bunker is built."

"You can place a 120mm howitzer on it."

"Reserve 20 boxes, 160 thermite shells of corresponding specifications."

"As for thermite bombs for drones, you can produce 50 of each in 20 kg and 40 kg specifications."

Because thermite raw materials are common enough and cheap enough.

Su Wu was quite generous when planning ammunition reserves. Basically, he calculated the standard of being able to achieve a saturation strike lasting more than 10 minutes.

Here we are.

The firepower configuration of the shelter is actually extremely sufficient. It is even sufficient to the point of being a bit excessive.

Not to mention the Owen shelter as the imaginary enemy, it is just a medium-sized enterprise shelter with just over 10,000 people.

Even if it is used to fight against a company-level army, there is no big problem.

But even so, Su Wu still feels that it is not safe enough.

His eyes fell on the three-dimensional map of the shelter, the vertical drone lift channel connecting the shelter and the small bunker that has not yet been built.

An idea quietly emerged.

There is already a ready-made vertical launch silo, why not have another big one.

He opened the database for a simple search.

A 240 mm diameter rocket design drawing jumped out from it.

The manufacture of related military weapons has been included in the work schedule of the engineering robot.

Check the time.

The concrete of the first layer of the small bunker on the ground should have been initially hardened.

Su Wu dispatched all eight construction robots, concrete mixers, and a mini excavator from the engineering team on the fourth underground floor to continue building the second floor.

Compared with the nearly 6-meter height of the first floor of the bunker, the height of the second floor is only about three meters, and the amount of work is also reduced accordingly.

With the joint efforts of the eight construction robots.

It is expected to be completed in two to three hours at most.

Then it is necessary to wait for another 8 hours of hardening time, continue to build the third floor and cap it, and then the entire small bunker can be declared completed.

After handling the affairs inside the shelter.

Su Wu continued to command the urban convoy to clear the road.

In the evening.

When the large transport truck had made more than 5 round trips and pulled hundreds of tons of construction waste back to Su Wu's shelter.

The first passage leading to the nearest official shelter entrance was completely opened.

Su Wu operated a construction robot and rushed to the material warehouse of the official shelter as soon as possible to extract his materials.

"You have deposited 220 tons of steel and 300 tons of fertilizer here."

"It's just that--"

The warehouse manager hesitated.

"What's wrong?"

Su Wu raised his eyebrows, and his voice sounded a bit cold and hard through the relay of the construction robot.

"Nothing, I'll pick it up for you now."

The manager seemed to have realized that he was not behaving properly and showed an apologetic expression.

He lowered his head and printed out a list of outgoing goods on the computer and handed it to the construction robot controlled by Su Wu.

Then hesitating for a while, he couldn't help but speak.

"You'd better take away all the deposited things before tomorrow morning."

"I heard from our supervisor that there is a big gap in the supply of the shelter now, and we are considering temporarily collecting civilian supplies to make up for it."

"If we move slowly, we may only get an IOU in the end."

For an administrator who is just a low-level worker, the collection of supplies from above is not only good or not, but the disadvantages are just on his face. He must face the representatives of the civilian shelters who have lost supplies and be the first to bear their anger.

If you don't handle it properly, you might end up bleeding on the spot.

The administrator secretly glanced at the steel-structured robot in front of him, and his heart was even more bitter.

A shelter that can afford robots is not likely to be easy to mess with. Making a gun is probably as easy as playing.

When a conflict occurs, no matter what the outcome of the other party is, he will definitely be the first unlucky person to be sacrificed.

"Collecting supplies?"

Su Wu was not surprised to hear this. He was so keen on cleaning up the city roads, not just to prevent such things.

Under a highly centralized system, especially in the early days of the end of the world, when the constraints from the peaceful era are getting lower and lower, it is normal to tear up contracts and oppress the weak.

Giving an IOU is considered a kind heart of the manager.

"I see, thank you for reminding me."

"I will take away all the remaining supplies before seven o'clock tomorrow morning."

Su Wu came back to his senses and gave a clear answer without making things difficult for the staff opposite.

"That's good, there shouldn't be any problem before seven o'clock."

"Our supervisor won't come that early."

The administrator breathed a sigh of relief. No matter what, it was a good thing to push a trouble away.

Received the delivery list.

With the help of several forklifts operated by the workers of the official shelter, 20 tons of fertilizer were loaded into the compartment of the large truck in less than an hour.

Watching the large truck on the screen, it began to return to the shelter along the cleared streets.

Su Wu fell into deep thought.

He began to seriously consider how to deal with this accident.
