Doomsday disaster: Start by building a shelter

The more he analyzed, the more dissatisfied Su Wu was with the combat capability of the construction robot.

But this is a problem of infrastructure and hardware.

Unless it is completely re-designed. Otherwise, there is no way to solve it.

"I was lucky this time, but I may not be lucky next time."

"I can't continue like this."

After the review, Su Wu took a deep breath.

The pressure and sense of crisis caused by this unexpected encounter made him realize that he must build a more professional armed force.

To deal with the threat from the same kind under the gradually collapsing order of the doomsday.

However, how to do it specifically made him a little embarrassed for a while.

It is okay to develop armed forces, but it cannot occupy too many resources, and it must have a crushing advantage in battle.

Otherwise, there is no meaning in development.

After thinking hard for more than ten minutes.

Finally, Su Wu set his sights on the field of drones.

This time, the supplies he purchased from the official shelter included various models of commercial drones.

The most expensive one is the K2 series agricultural drone.

As a mass-produced commercial drone, the K2 series agricultural drone has many obvious shortcomings.

Its fuselage is mainly made of plastic and thin metal sheets, and its own defense is almost zero. Even if it is hit by a fist-sized stone in the front, it may crash on the spot. The mass-produced motor and poor cooling system allow it to work normally only in an environment below 65 degrees. At the same time, the fastest flight speed is only 3 meters per second, and the maximum flight altitude is below 200 meters. It is not as fast as a normal adult.

But all these shortcomings cannot erase and offset its two extremely unique advantages.

It is an air unit and has a load capacity of up to 50kg.

These two advantages give the K2 series agricultural drone unlimited and broad modification potential.

The former allows it to ignore obstacles and terrain and easily reach any battlefield. The latter can carry enough ammunition and dominate the battlefield with absolute firepower.

"Choose it."

Su Wu made a decision.

He asked a construction robot to go to the warehouse and bring the only two K2 series agricultural drones to the manufacturing center.

Then scan, model, and draw the most accurate three-dimensional model.

To facilitate modification and design.

"First of all, in terms of positioning, it should be a long-range bombing weapon."

"With a load of 50kg, at least 40kg should be used to carry explosives."

Bricks fly with great force.

No matter what kind of enemy you face, a wave of bombs thrown over will definitely have the effect of clearing the field.

As for the source of explosives, Su Wu traded hundreds of tons of fertilizers and daily chemicals with the official shelter. Just refine them.

Although the quality may not be as good as the fine gunpowder obtained from the heavy knight. But it is more than enough to make bombs.

With positioning, the rest of the design is much easier.

In terms of bombing methods.

Su Wu rejected the inefficient method of throwing bombs directly, which is half-reliant on luck. He chose rockets that would sacrifice a certain amount of load, but have a longer range and are more accurate.

A K2 series agricultural drone has a total load of 50kg and can carry five single-soldier rockets with an average weight of 8.5kg.

The remaining 7.5 kg of load margin can be used to load other accessories.

For example, a more efficient cooling system allows the drone to fly normally in an environment of 85 degrees. For example, a more rigorous waterproof and air filtration system allows the drone to shuttle through the rain curtain and the smoke produced by burning.

There are also fine-tuning of the fuselage structure, so that the drone can quickly regain balance and continue to fly and fight with the assistance of artificial intelligence even if it encounters an attack, as long as the core components are not damaged.

A series of modification designs are constantly born in Su Wu's consideration.

Then through the simulation and calculation of artificial intelligence, it is transformed into a practical modification drawing.

Then with the help of engineering robots, it is actually installed on the K2 series agricultural drone.

More than ten hours later.

Two K2 series agricultural drones equipped with rocket launch nests appeared on the manufacturing table of the shelter manufacturing center.

They were officially incorporated into the combat command system of the shelter.

"Now we finally have a real armed force."

Looking at the icons representing two K2 series agricultural drones on the console screen. Su Wu felt satisfied and relieved.

And this is just the beginning.

There is still a lot of room for expansion.

After thinking about it.

Su Wu added a blueprint of a foldable shooting platform and asked the engineering robot to build ten according to the blueprint.

This shooting platform has a very simple structure.

It is composed of an assault rifle, a large ammunition compartment, a camera with infrared function, a base that can rotate 360 ​​degrees freely, and a microcomputer.

Its total mass is 40kg, and it can be folded into a metal box in dormant state.

It can be carried by the K2 series agricultural drone with empty rockets and airdropped to any designated location. Then after being dropped to the location, it automatically deploys a combat mode and attacks the target marked as the enemy autonomously or by the artificial intelligence in the shelter.

At the same time, in addition to going out to fight. They can also be deployed in farmyards on the surface and various key locations in underground shelters in normal times. As conventional shelter defense facilities.

"The rockets of the K2 series agricultural drones are the first line of defense."

"The folding shooting platform is the second line of defense."

"Finally, construction robots equipped with automatic rifles and engineering robots can form the third line of defense."

"With this kind of lineup, unless facing a regular army, it is unlikely that anyone will be able to attack the shelter."

Commanding the modified K2 series agricultural drones, rehearsing outside.

Across the screen, I witnessed a rocket it carried successfully ignite and accurately hit a small hill more than 200 meters away.

Su Wu finished his work with satisfaction.

. . . . . . .

The next few days.

Everything went smoothly.

Large trucks continued to transport the supplies purchased from the official shelter to the farmyard day and night.

Then the construction robots picked them up and stored them in the manufacturing center warehouse on the second underground floor of the shelter, the living material warehouse, and the feed planting area on the third underground floor according to their types. Some materials that are not picky about the environment and can be stored for a long time, such as cement, are directly piled in the simple sheds in the farmyard on the surface, or even in the two-story building where people originally lived.

With sufficient material support.

Su Wu quickly completed the final reconstruction of the breeding factory on the third underground floor. The purchased fish fry, eggs and duck eggs to be hatched, etc. were all settled in it smoothly.

At the same time, hundreds of soilless cultivation shelves in the feed planting area were all planted with seeds. Just wait for them to germinate and grow.

During this period, because the workload of the shelter increased a lot.

Su Wu had to spend another 15 survival points and add three construction robots to make up for the labor gap.

So far.

At the end of the second month of Su Wu's construction of the shelter, the number of his construction robots reached seven. The shelter began to show signs of prosperity.
