Doomsday disaster: Start by building a shelter

After the test was completed.

Su Wu immediately gave the first formal manufacturing task to this CNC machine tool, which may have reached the top performance in the world.

Assist the engineering robot to manufacture the unfinished 3D printer.

With the help of the CNC machine tool.

The manufacturing progress of the engineering robot seemed to have been fast-forwarded more than ten times.

The work that originally took six or seven hours to complete was directly compressed to less than half an hour.

Su Wu simply did not leave the manufacturing center.

He stood near the manufacturing table and watched the two engineering robots and CNC machine tools work.

He did not take a few steps forward until they were completed.

Compared with the huge CNC machine tools.

The size of the 3D printer is much smaller, almost half the size of a room.

But the resources it consumes are also not small.

At the very least, with the current material reserves of Su Wu's shelter, it is basically impossible to manufacture a second 3D printer.

Reach out and press on the still warm metal shell of the 3D printer.

New upgrade options popped up in Su Wu's field of vision.

"Choose to upgrade, integrated 3D printer."

Su Wu chose the most expensive upgrade option. The survival points in his hand disappeared by 50 points instantly.

White light was blooming.

A device emitting silver-white metallic light was quietly born.

The upgraded 3D printer.

It can use metal and non-metal materials, such as rubber, glass, etc. to print items.

The production efficiency is much lower than that of CNC machine tools. But the advantage is that it can shape items arbitrarily without material restrictions.

It can also print more precise parts.

Even if the materials provided are sufficient, some low-end micron-level chips can be printed.

This is especially important for a shelter controlled and managed by artificial intelligence and full of technological attributes.

"Master the production equipment."

"Then solve the material reserve problem."

"Next, the production capacity will explode."

The sight was patrolling the CNC machine tools and 3D printers, two industrial heavy tools that are currently priceless treasures.

Su Wu couldn't help but have a lofty ambition for the future.

Larger, city-like underground shelters and endless automated machinery and equipment may no longer exist only in fantasy.

However, in order to turn fantasy into reality.

Su Wu still has many difficult hurdles to overcome.

The first is the quality of materials.

Unlike the manual operation of engineering robots, CNC machine tools and 3D printers have several levels higher quality requirements for raw materials.

In this case.

Most of the materials removed from the old household appliances in Su Wu's shelter cannot be used directly.

They must be further disassembled and re-melted.

"It just so happens that the fourth underground floor of the shelter has been completed."

"Now the demand has come up."

"Let's start by building a production line for dismantling and smelting scrap metals."

Facing the first problem that needs to be solved for the explosion of production capacity, Su Wu naturally thought of the fourth floor space that has not yet been officially completed and line pipelines have not been arranged.

According to the original plan.

The fourth floor would also be used to build a small industrial zone integrating dismantling, smelting and production manufacturing.

Now, because the performance of CNC machine tools far exceeds expectations, it provides powerful production and manufacturing capabilities.

The part of the original plan about small production lines can be directly discarded. The freed-up space can be used to build larger-scale disassembly and smelting equipment.

"But we can't fill up all the places."

"We need to leave a small space to assemble large vehicles and equipment such as trucks."

With the emergence of CNC machine tools and 3D printers, the originally spacious manufacturing center began to look a bit crowded. The land left for engineering robots to assemble is quite limited.

In this case, if you want to assemble some large items, you must find another place.

The 4th underground floor is almost the only option at present.

"Let's start building."

After planning the layout of the 4th underground floor.

Su Wu immediately started working on the spot.

A large amount of finished steel and some other raw materials began to be transported to the manufacturing center by construction robots and put into CNC machine tools and 3D printers.

And at this time.

Su Wu suddenly received an alarm from artificial intelligence.

A suspicious team appeared near the surface of the shelter.

Su Wu switched the screen on his tablet to surveillance. With the help of the AI ​​identification, he quickly found the target.

It was a group of about ten people, all wearing heat-insulating suits and holding guns.

They wandered around the small bunker on the ground within two or three kilometers, using telescopes and drones to observe the surface facilities of the entire shelter.

Not far behind them, there were several construction vehicles parked.

It seemed that they were tools prepared to forcibly demolish the shelter after Su Wu closed the door.

"They came quite quickly."

"They didn't even want to wait at night."

There was no surprise on Su Wu's face. As early as when he exposed the scale of the hydroponic factory, he knew that there was a high probability that he would encounter this scene.

I just didn't expect that the people who were secretly watching would be so impatient that they didn't even want to wait for a few hours.

They brought people here in broad daylight.

"Send out reconnaissance drones to shoot battlefield videos."

"K2 series agricultural drones start loading rockets and stand by."

"Activate 120mm howitzers and destroy them."

The engineering team that was digging the fifth underground floor did not even stop working, and the door to the shelter exit passage was not closed.

Su Wu simply gave the artificial intelligence a few combat orders.

Soon.

With the drone lifting platform sending a reconnaissance drone into the air, the surrounding area of ​​several kilometers was included in the monitoring perspective.

A nearly unilateral massacre began to break out without warning.

More than a thousand meters away from the small bunker on the ground.

A captain-like man seemed to have noticed something unusual. He raised his head and tried to find the source of his inner uneasiness.

And the next moment, his pupils shrank violently.

He saw a shell falling from the sky and hitting near his two companions hundreds of meters away.

Then the next second, endless flames bloomed like fireworks. Instantly covering the surrounding area of ​​nearly 100 meters.

Completely engulfing the figures of his companions.

He couldn't help but open his mouth wide, and felt his hands and feet go limp in horror.

"What is this?"

"Aren't they here with guns to cause trouble for a private civilian shelter?"

"How could they encounter such a terrible attack--"

However, on the battlefield, being dazed is an extremely deadly thing.
