Cataclysmic Era: I can unlock the tech tree

The heavy burden in Lü Yongchang's heart suddenly eased.

It's fine as long as it's not a pastoral civilization.

But the next moment, a new kind of confusion arose in Lü Yongchang's mind.

If it's not an idyllic civilization, then what's the origin of that technologically advanced spherical flying object outside the Gliese 555 star system?

As Lü Yongchang stared at the holographic projection, he suddenly realized something.

"Only one?"

Lü Yongchang glanced at Fang Xu with surprise: "Aren't there any other similar flying objects?"

Fang Xu shook his head, somewhat puzzled, and replied, "So far, the antimatter collection device has only detected one unidentified flying object."

Lu Yongchang's expression changed slightly.

This act of venturing into an unfamiliar star system all by himself...

"A detector?!" Lu Yongchang and Fang Xu exclaimed in unison.

Upon hearing the other person express their inner thoughts, both of them smiled knowingly.

"It's just a detector, that's fine." Lü Yongchang breathed a sigh of relief and said with a relaxed expression, "You scared me! I thought the Pastoral Faction had found us so quickly!"

Fang Xu's face was also full of relief: "Yes, I wonder what level of civilization would take a liking to such a barren star system."

"It probably isn't some advanced civilization."

Lu Yongchang chuckled and nodded in agreement, then casually asked, "Zero, how did it appear? From which direction did it come?"

"Pull up the video and let me see it."

The words fell.

The holographic projection image changes rapidly.

A familiar scene then appeared before him.

Darkness, deathly silence, only the distant, scattered lights offered a sliver of reassurance.

Suddenly, the tranquil and deathly still scene began to change slightly.

Without any warning, a dark gray spherical flying object suddenly appeared in the picture.

Upon seeing this scene, Lü Yongchang felt a jolt in his heart.

broken.

This strangely familiar scene directly touched the DNA of everyone present.

"Holy crap!" *N

"Warp drive!!"

Suddenly, the laboratory, which had just returned to tranquility, was plunged into "panic" once again.

The relaxed expression on Lü Yongchang's face had completely vanished, replaced by an unprecedented sense of solemnity.

"How is that possible..."

"Possessing warp drive technology means they are at least a Type IV civilization that has reached a certain level of development."

"How could they possibly be interested in this barren land?!"

Without time to think, Lü Yongchang said directly, "Zero, send out detectors and adjust the position of every antimatter collection device nearby. I need to see the entire detector!"

"receive!"

The moment the electronic synthesized voice sounded, the angle of the image in the holographic projection also began to change.

The camera slowly pans.

The full picture of the detector then came into view before the group of researchers.

suddenly.

"What about its power system?!"

Fang Xu's utterly horrified voice came from the side: "What's driving it?!"

Lu Yongchang did not reply, but stared at the holographic projection in front of him with a gloomy expression.

There is no Hall thruster.

There is no antimatter engine nozzle.

There are no messy propulsion system nozzles either.

The entire detector is a perfectly round sphere!

But this sphere is steadfastly heading towards the Gliese 555 star system!

What a big deal!

Only these four words remained in Lü Yongchang's mind.

Although the pastoral faction didn't come, an equally terrifying advanced civilization did!

"Professor, the probe has reached its destination."

The moment the electronic synthesized sound rang out, dozens of detectors appeared in the holographic projection.

Lu Yongchang frowned, pondered for a moment, and then said directly, "Send a signal to it!"

"Ask it why it came."

……

Outside the Gliese 555 galaxy.

In the cold, desolate expanse of space, a dark gray spherical probe moved slowly and steadily forward along its original trajectory.

Dozens of human-made probes followed it, sending it electromagnetic waves at 1420 MHz.

This is an experience I learned from painting.

But clearly, the civilization behind this probe is not as easy to talk to as [the painting].

Faced with the electromagnetic waves, the spherical probe made no response and continued to move toward the Gliese 555 galaxy.

Inside the Dawn Star First Laboratory.

Lu Yongchang stared at the holographic projection with a grim expression.

This arrogant attitude unique to advanced civilization gave him a bad feeling.

"Zero, move the detector closer to it and check its data."

Lu Yongchang managed to squeeze out an order.

……

More than ten minutes later.

A continuous stream of data appeared on the giant holographic projection in front of everyone.

Inside the laboratory, as lines of data were displayed, the atmosphere grew increasingly cold.

"This, this is impossible..."

Lu Yongchang's hands trembled slightly as he looked at the data in front of him in disbelief.

Based on the various observation data transmitted back by the probe, this dark gray probe is a perfectly spherical object.

Its surface is without the slightest error.

Or rather, with current human technology, it is impossible to detect the errors that exist!

Moreover, under the scrutiny of a high-precision camera, its surface shows absolutely no seams or joints resembling welds.

It's as if it were molded from a single piece!

This made Lü Yongchang think of an incredible technology.

"Strong, strongly interacting materials?"

Only a substance that exists only in theory could possibly be used to create such a detector!

"What level of civilization's probe is this?!"

A terrified voice came from the side: "Level six? Or level seven?!"

"It's possible..." Lu Yongchang paused for a moment, then said in a low voice, "It's level eight."

"Civilized cleaners."

The laboratory was completely silent.
