Age of Cataclysm: I can light up the technology tree

The next day.

A Xuannv 2 flew out from the Earth and flew straight towards Proxima Centauri b, which appeared dim yellow in the distance.

Like the small spacecraft of Proxima Centauri, the smaller Xuannv 2 also appears to be extremely flexible.

Especially when there is no driver inside, its acceleration performance reaches its peak!

Soon, it reached the synchronous orbit of Proxima Centauri b.

Under Zero's control, Xuannv-2's flight trajectory was extremely graceful.

It didn't stop at all and plunged into the dim yellow atmosphere of Proxima Centauri b.

After entering the atmosphere, Xuannv 2's flight speed slowed down slightly, but it still dived towards the ground like a sharp sword!

The fierce friction between the ship's hull and the atmosphere instantly turned Xuannv 2 into a fireball that hit the ground!

Just before it was about to make contact with the ground, Xuannv 2's speed instantly slowed down.

Like a miracle, it once again drew a beautiful curve and changed its flight trajectory.

At this moment, it is located on a vast ocean.

Under Zero's control, Xuannv No. 2 chose a direction and rushed forward quickly!

…

A certain continent in Proxima Centauri b.

Xuannv 2 slowed down its flight speed again and landed slowly on solid land.

After a short wait, its belly door suddenly opened, and small drones flew out one after another.

After the drones circled in the air, they scattered and flew straight towards their respective targets!

…

[Earth] Command Center.

Atmospheric composition, surface temperature, geological features...

Various data are presented in a huge holographic projection in front of everyone.

The camera footage then came.

The ground is filled with large and small craters.

In the distance, there are countless building debris and ruins.

You can imagine how much impact those electromagnetic cannon projectiles and interstellar smoke bombs had on the surface of Proxima Centauri!

Everyone looked at the dilapidated scene in front of them, and couldn't help but feel a little emotional in their eyes.

Lu Yongchang did not pay too much attention to the "scenery" on the surface. He looked at the atmospheric data of Proxima b and said with a frown: "The oxygen content is a bit low, and there are still a lot of toxic gases..."

"It seems that we will still have to live in the quarantine cabin by then."

"There's nothing we can do about it." Fang Xu's voice came from the side. "Although there are countless planets in the universe, finding a planet with an environment similar to the earth's is like finding a needle in a haystack."

Lu Yongchang naturally knew this truth, but even so, there was still a look of regret on his face.

Fang Xu shrugged and continued: "What's more...not to mention the composition of the atmosphere, the radiation caused by the nuclear bombs we launched is enough to give people a headache."

Lu Yongchang laughed dumbly: "Zero, have you found any traces of Proxima Centauri people living there?"

Zero's avatar appeared in front of everyone.

"Currently, no signs of Proxima Centauri survival have been found on the surface."

Hearing this, Lu Yongchang was slightly startled, and subconsciously asked: "What about the underground?"

"Underground exploration is currently underway, and no abnormal structures have been discovered yet..."

As soon as he finished speaking, Zero suddenly changed his words and said: "Correction, an abnormal structure in the underground has been discovered."

A 3D model is presented in a holographic projection.

Under the undulating ground, a huge hole suddenly appeared!

The entire cavity is disk-shaped, very similar to the structure of the Proxima Centauri starship.

"This is it."

Seeing this extremely obvious trace of man-made creation, Lu Yongchang said categorically: "Zero, send some drones over to investigate carefully. I want to know the location of its vents and other information."

…

More than an hour later, Lu Yongchang looked at the information in front of him and took a deep breath.

"Trouble..."

"These Proxima people built the dungeon like a turtle shell... They didn't even leave any vents!"

Like Lu Yongchang, everyone else's expressions were also ugly at this moment.

The lack of vents means that the genetic weapons that humans are planning to release cannot enter the so-called underground city through the atmosphere.

"Professor, we found the elevator." Zero's voice sounded again, "It's just that it's locked."

The camera footage showed a completely black cabin standing next to a huge crater.

The door to the hut was closed.

From the outside, there doesn't seem to be anything out of the ordinary about this cabin.

But the craters around it and the construction debris scattered all over the place show how special this cabin is!

It perfectly withstood continuous nuclear bomb attacks!

"We can send robots to cut it open." Zhao Zijie's voice came from the side, "and then put genetic weapons into it."

Lu Yongchang slowly shook his head: "No."

"That's not a good idea."

"This is just their elevator. The other party will definitely be able to cut off this passage."

"Once we alert the enemy, we lose the opportunity to use this weapon."

Lu Yongchang hesitated for a moment, then spoke again: "If they continue to huddle underground, it will be difficult for us to quickly deal with these Proxima Centauri people."

"It's an extremely stupid thing to have a street fight on the opposite side of the property."

Zhao Zijie pursed his lips hard and scratched his head in distress: "Then... what should we do now?"

This situation is not introduced in the interstellar war simulation class.

Not only him, but every captain and starship pilot had a distressed look on their faces.

They knew how to use various weapons and understood various military tactics, but they had no idea about this unknown situation.

Lv Yongchang, on the other hand, had a smile on his face.

He clapped his hands with a relaxed look on his face and said in a relaxed tone.

"Let them continue to shrink in their tortoise shells."

"We let the genetic weapons go in by themselves."

Looking at the puzzled eyes cast by everyone, the smile on Lv Yongchang's face became more and more obvious.

"Everyone, the next step is my job."

Just as Lv Yongchang was about to turn around and leave the command center, Zero's voice sounded again.

"Professor, we found a second abnormal underground structure."

"The similarity of the two underground structures reached 90%."

Lv Yongchang paused suddenly.

"Okay, I know."

"It seems that these Proxima people have built two tortoise shells."

...

A week later.

Two Xuannv II flew out of the Earth and headed towards Proxima b along the same route.

A few hours later.

The two Xuannv IIs stopped in front of two similar black cabins.

The hatch slowly opened.

Countless silver-white substances flew out of the cabin, circled twice, and flew towards the black cabin.

They were modified nanorobots.

In order to increase endurance and carry genetic weapons, the size of these nanorobots is several times larger than the prototype.

Even so, they can still easily enter the cabin through various gaps, and then use the elevator to enter the underground city that looks like a turtle shell!

PS. Ahem... I only have time to write one chapter today, so I'll take a day off.
