Upon hearing Lü Yongchang's words, Fang Xu couldn't help but shake his head with a wry smile.

Too.

If genetic weapons don't work, then they will naturally have no choice but to choose the most time-consuming and laborious method to carry out their genocide plan.

Even though these Proxima Centauri people have locked themselves underground.

For the time being, they pose no threat to humans.

But as the old saying goes...

How can I allow others to sleep soundly beside my bed!

Not to mention, humans have just seized their territory. If we don't carry out the genocide plan now, are we just waiting for them to come back for revenge later?

For these very reasons, no one present opposed Lü Yongchang's extermination plan.

As the image of Proxima Centauri b's surface gradually became clearer in the holographic projection, the atmosphere in the command center grew increasingly tense.

[Landing countdown: 5 minutes]

...

The Xuan Nu No. 2, lined up in neat formation, swept across the ground.

Compared to a little over a month ago, Proxima Centauri b now appears even more dilapidated.

The intense nuclear radiation did not inhibit plant growth; on the contrary, it even promoted the growth of plants on Proxima Centauri b that had strong radiation resistance.

Furthermore, with no activity from the Proxima Centauri, the surface of Proxima Centauri b was covered with incredibly lush vegetation.

Unlike Earth, the plants on Proxima Centauri b are mostly dark in color.

Aside from black, there is also a deep purple that is extremely close to black.

This is because Proxima Centauri belongs to the M-type star in the stellar spectrum. Proxima Centauri b, which is extremely close to its host star, has a large amount of infrared light. Therefore, these plants have a wider range of choices between visible and infrared light.

These dark-colored plants covered the dilapidated buildings in just one month.

The two have extremely similar colors.

That is why, at first glance, there are no obvious traces of civilization on the surface of Proxima Centauri b.

Only one area stood out conspicuously.

The once flat land is now covered with countless bomb craters, some deep and some shallow.

There are few plants in the crater, so the soil retains its unique yellowish-brown color.

Against the tan background, a touch of black stands out.

As the altitude of the Xuan Nu II gradually decreased, the images transmitted by the camera gradually became clearer.

It was a small, entirely black house.

This is the destination of these Mystic Maidens IIs—the entrance to the elevator in the Proxima Centauri underground city.

...

A fully armed army of robots stepped out of the Xuan Nu II.

A bright red, high-energy laser beam shone directly at the door of the black cabin.

Faced with a high-powered laser beam, the tightly closed door could only hold for a few seconds before being forced to give way.

Several robots, carrying cables supported by carbon nanotubes, entered the small house with heavy steps.

The interior of the cabin was almost identical to what it had been a month ago.

The only difference is the density of vegetation on the wall.

The area covered by those moss-like plants is much larger than it was a month ago.

The dim, orange light shone through the plants, illuminating the robot's silver-white body and adding an eerie warmth to the incongruous scene.

Watching this scene from afar aboard the Earth, Lü Yongchang's expression grew even more solemn.

"The underground city's energy supply has not been cut off."

"Zero, prepare for a counterattack."

As soon as the words were spoken, several robots in the camera lens raised their Gauss rifles.

The principle is the same as that of an electromagnetic railgun; the only difference between the two is the power level.

Even though the Gauss rifle is far less powerful than a shipborne electromagnetic gun, its power is still beyond what ordinary carbon-based life forms can withstand.

The coordination between these robots under Zero's control is breathtaking!

Whether for vigilance or construction...

All robots have their own assigned tasks, and their routes of action and tasks do not conflict in the slightest.

The orderly behavior gave Lu Yongchang and other remote spectators a sense of comfort from the bottom of their hearts.

In just over ten minutes, a simple elevator was set up.

Dozens of robots boarded the elevator, and under Zero's control, the elevator slowly descended.

...

The landing time was short.

A few minutes later, a ray of orange light emanating from the bottom appeared in the camera's view.

As they got closer, the group gradually made out the object emitting the orange-yellow light.

A wide-open door.

The gate was buried under some huge rocks and metal blocks, and the orange light shone through the gaps between these objects.

Lü Yongchang remembers it very clearly.

The last time the nanobots came, this door was tightly closed!

Could it be... that the genetic data sent by Proxima Centauri is really wrong?

Is this a trap set by the Proxima Centauri?

Have they already set up an ambush?

In an instant, countless suspicions flashed through Lü Yongchang's mind.

"stop!"

He said in a hurried tone.

Almost simultaneously, the elevator's descent speed was reduced to zero, and it came to a steady stop in place.

At the same time, dozens of robots on the makeshift elevator picked up Gauss rifles, quickly walked to the edge of the elevator, and pointed their guns at the open door.

The command center was silent. Lü Yongchang held his breath and stared intently at the holographic projection in front of him.

He could even hear his own heart pounding.

After waiting for a long time, he opened his mouth slightly and let out a long sigh of relief.

There was no movement.
