Cataclysmic Era: I can unlock the tech tree

Lu Yongchang stared blankly at the robot in front of him.

After a brief moment of reaction time, his expression changed drastically!

His already pale face looked even worse.

His breathing became rapid.

"Did something happen to the 2D core?"

The thought immediately arose in Lü Yongchang's mind.

As he spoke, he struggled to sit up in the deep-sea cabin.

The robot in front of me shook its head in a human-like manner: "It's not a two-dimensional core."

"It is a creation of an alien civilization."

"The Type I emergency response plan has been activated."

Lu Yongchang froze on the spot, muttering to himself, "An alien creation?"

A holographic projection quietly unfolded in front of him.

At the very center of the array of dozens of spherical detectors is a dilapidated "ancient" detector.

Yes, it is indeed an "ancient" detector.

The way the exposed wires were arranged, along with the circuit board structure and various sensors, reminded Lü Yongchang of time on Earth.

I vaguely remember that hundreds of years ago, humans also relied on these old and worn-out probes to explore the universe.

A hint of emotion flashed in his eyes, and his tense body relaxed slightly.

Lu Yongchang struggled to climb out of the deep-sea compartment: "Has the others woken up?"

"Awakening procedure is in progress. Currently, the following personnel have regained consciousness..."

Looking at the long list in front of him, Lü Yongchang nodded in satisfaction: "Tell everyone that once they have recovered, they should immediately assemble at the command center."

"By the way, send a Xuan Nu II to conduct a close-up investigation of this probe."

Zero replied without hesitation: "Received."

……

Meanwhile, in outer space outside 1AU, a breathtaking scene is unfolding!

The unidentified square detector moved using Hall thrusters at its tail.

However, its Hall thrusters are clearly no match for those used by humans.

Compared to spherical detectors, square detectors travel at an extremely slow speed.

Even so, because the two are moving in opposite directions, their relative speed still reaches an extremely high level.

This added considerable difficulty to the interception mission.

One probe changed its course and flew to the side of the square probe, using its own body to strike the Hall thrusters at the tail of the square probe.

With zero precision control, a visual feast, like an "aerial scalpel," slowly unfolds!

The spherical detector kept touching the body of the square detector from the side.

One, two, three...

Ultimately, the dilapidated square detector could no longer withstand the humiliation.

The Hall thrusters have "gone on strike".

After ensuring that its propulsion system stopped operating, three more spherical probes changed course.

The three spherical detectors tightly sandwiched the body of the square detector and began to slowly decelerate.

Gradually, under the influence of the spherical detector, the speed of the square detector slowly decreased.

……

Half an hour later.

"You should all be aware of the situation."

"Enough with the small talk."

"Now that everyone's here, let's begin the reconnaissance!"

Seeing that no one objected, Lü Yongchang changed the subject and said to Zero, "Zero, prepare to capture the detector!"

……

Outside of 1AU.

With the combined efforts of the three spherical detectors, the square detector successfully changed its direction of travel and was accelerated to a speed that was not its own.

At this moment, the square probe remained relatively stationary compared to the human fleet.

This also provides favorable conditions for the subsequent close-range exploration.

Xuan Nu No. 2 slowly approached, waving its mechanical arm.

Under everyone's watchful eyes, it steadily grasped the square detector.

The robotic arm retracted into the cabin and brought the probe inside.

The electromagnetic wave signals continuously emitted by the square detector were also completely shielded.

As soon as it entered the cabin, several robots carried the probe, which was covered with stories, onto the "dissection table".

Several laser beams streaked across the sky.

The detector's battered outer shell shattered completely, revealing the meticulously designed circuit boards and sensors inside.

……

Looking at the images in the holographic projection, the caution in Lü Yongchang's eyes dissipated somewhat.

the reason is simple.

Although the shape and wiring are different, he can still recognize that it belongs to a Type I civilization probe.

Lu Yongchang frowned, a hint of doubt in his eyes: "How did a Level 1 civilization's probe get here?"

"There shouldn't be any star systems around here, right?"

Zero quickly replied, "Yes, the nearest star system is 5 light-years away."

"Perhaps..." He Bilin's voice came from the side, "...like the Voyager probes that humanity sent before?"

After a moment's thought, Lü Yongchang nodded silently: "At present, this is the only possibility."

Looking at the flashing red indicator light, Fang Xu suddenly asked, "Has the other party responded to our message?"

"We have not received any information yet."

After glancing at the detection data and noticing that the detector was still emitting electromagnetic waves, Lü Yongchang said nonchalantly, "That's normal."

"The other party probably hasn't mastered long-distance communication technology yet and is still using electromagnetic wave communication."

"Zero, are you sure these electromagnetic waves haven't traveled out?"

For safety's sake, Lü Yongchang checked it again.

"Currently, no abnormal electromagnetic signals have been detected outside of Xuan Nu II."

Lu Yongchang nodded in satisfaction: "Continue disassembling."

"Be as careful as possible, this is an antique."

Perhaps because he realized that the other party was not as strong as him, Lü Yongchang felt more relaxed and even made a small joke.

A laser of appropriate power glides across the detector surface, slowly cutting the detector apart.

"Hall thrusters, small fusion reactors..."

"It does resemble the second-generation Hall thruster somewhat."

Lu Yongchang glanced at it and then lost interest.

That's too outdated.

Just as he was about to turn around and sit down, a strange device caught his attention.

A small black box was quietly embedded in the cut-open casing of the detector.

He noticed the anomaly at a glance.

Compared to the surrounding components, the black box looks out of place.

Its workmanship is on a completely different level from that of the detector!

Lu Yongchang paused, his expression immediately turning serious.

"Zero, focus your inspection on that black box!"

A laser of the same power swept across.

The black box showed no abnormalities.

Lü Yongchang's expression changed drastically.

broken!

This is definitely not the creation of a first-class civilization!
