It's reasonable for me to have a two-way foil for a second-level civilization, right?

"Professor, the probe has arrived at its destination."

The moment the electronic synthesizer sounded, dozens of detectors appeared in the holographic projection.

Lu Yongchang frowned, and after thinking for a moment, he said directly: "Send a signal to it!"

"Ask where it came from."

……

Gliese 555 exoplanet.

In the cold and dead cosmic space, a dark gray spherical detector moved slowly and steadily along the original direction of travel.

Dozens of human detectors followed it, sending it electromagnetic waves of 1420 megahertz.

This is the experience I learned from [Hua].

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

In the face of the electromagnetic waves, the spherical detector did not show the slightest, and continued to go its own way towards the direction of the Gliese 555 star system.

Inside the first laboratory of Dawn Star.

Lu Yongchang looked at the picture in the holographic projection with an ugly expression.

This kind of arrogance unique to advanced civilization made him feel bad.

"Zero, control the detector to approach it and check its various data."

Lu Yongchang squeezed out an order with difficulty.

……

After ten minutes.

A steady stream of data appeared on the huge holographic projection in front of everyone.

In the laboratory, with the display of rows of data, the atmosphere became colder and colder.

"This, this is impossible..."

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

According to the observation data sent back by the detector, this dark gray detector is an extremely standard sphere.

There is not the slightest error in its surface.

In other words, with the current technology of human beings, the existing errors cannot be found!

Not only that, under the shooting of high-precision cameras, its surface has no joints like welds at all.

It's as if it was formed in one piece!

This made Lu Yongchang think of an incredible technology.

"Strong, strongly interacting force materials?"

It is only this kind of matter that exists in the theory that it is possible to create such a detector!

"What level of civilization is this detector?!"

Fang Xu's horrified voice came from the side: "Level six? Or seven?!"

"It's possible..." Lu Yongchang was silent for a while, then said in a low voice, "It's level eight."

"Sweeper Civilization."

In the laboratory, there was no sound.

Chapter 533 "Warning"

Lu Yongchang's words brought the atmosphere in the laboratory to a freezing point.

"Clear... the civilization of the sweepers?"

Fang Xu beside him swallowed hard, his pupils trembled slightly, and he muttered to himself in shortness of breath, "He, why did they come to us?"

Lu Yongchang didn't speak, but quickly sorted out all the known information in his mind.

After a few seconds, he let out a long breath.

"I understand……"

Lu Yongchang's face was gloomy, and his straight waist was slightly bent at this moment.

He murmured in an extremely low voice: "That message was not sent to the pastoral group..."

"What, what?"

Hearing Lu Yongchang's words, Fang Xu was stunned, and subconsciously asked, "What information?"

Seeing the dejected look of Lv Yongchang, who is the backbone, Fang Xu suddenly became anxious.

"I said Yongchang, when is this, what information is there?!"

"right now we……"

Lu Yongchang raised his hand to support the experimental table in front of him, and interrupted Fang Xu's words in a heavy tone: "Do you still remember the last distress message of [Painting]?"

Fang Xu was taken aback for a moment, then nodded: "Of course I remember..."

Before the words fell, Fang Xu's eyes widened suddenly!

He seemed to realize the meaning of Lu Yongchang's words!

"what do you mean……"

"That message was sent to the Sweeper Civilization?"

"No, aren't they enemies?!"

Lu Yongchang shook his head slowly, and corrected softly: "It's not for the sweeper civilization."

"If I'm not mistaken, that incomplete message should be a broadcast to the entire universe."

"At least, it is a broadcast for those advanced civilizations in the universe."

Before Fang Xu could ask, Lu Yongchang continued: "The Type II or Type III artificial intelligence that [Hua] mentioned belongs to dangerous technology."

"It's understandable that it wants to nip this danger in its infancy."

"Fortunately, Zero solved the [painting] in time, and its information was not fully sent."

"Human civilization is now famous in the universe."

Lu Yongchang's voice was a bit bitter.

It's not a good thing to be famous at this critical time!

Thinking of the scene where all the advanced civilizations in the universe have focused their attention on a corner of the Milky Way, Lu Yongchang felt a chill coming from behind.

"Professor, I think..."

Tao Yuda's voice came from not far away: "We shouldn't think so far away now..."

After speaking, Tao Yuda stared straight at the huge holographic projection in front of him, swallowed and said again: "That detector seems to have stopped."

……

Gliese 555 exoplanet.

The dark gray spherical detector stopped its progress and hovered quietly in the universe.

While the antimatter collection device and detectors are jointly investigating, the detectors from the Sweeper civilization are also investigating the surrounding technological creations.

The type I artificial intelligence built into the spherical detector is constantly comparing the collected data with the data from [Hua] in the database.

The content of the comparison is naturally the style of these technological creations.

Every civilization in the universe has a different living environment, different life forms, and different types of technology mastered. Therefore, the styles of civilization creations are also various, and there is almost no possibility of the same.

Therefore, the style of civilization creation has also become the "identity card" of civilization in the universe.

At this time, the detector from the sweeper civilization is completing this comparison work-it needs to make sure that it has not found the wrong person.

A piece of information is sent to the central black hole region of the Milky Way in a form that humans do not understand.

[Number: Probe No. 912133165, has successfully arrived at the target star system. 】

[Technological creation detected, performing comparison task...]

[The comparison is completed, the similarity is 99%, and it is confirmed as human civilization. 】

[Civilization level judgment in progress...]

[Warning: This civilization has mastered antimatter technology, and the mission is at risk of failure. Do you want to continue? 】

【warn……】

……

"what's the situation?"

Lu Yongchang frowned, staring blankly at the picture sent by the camera.

"What exactly does this sweeper civilization mean?"

Facing Lu Yongchang's questioning, there was silence in the laboratory.

All the researchers shook their heads in confusion.

"Zhuo!" Lu Yongchang swears in a rare way.

This is not as good as rushing directly into the Gliese 555 star system!

At least in this way, humans can attack it with impunity.

If you win, everyone is happy; if you lose, you can wait for death with peace of mind after starting the [Dandelion] plan.

But now this non-stop operation made him feel confused.

What to do next?

Fight back?

No one has stated their intentions for coming, maybe it was a misunderstanding?

The first shot of war must never be fired by human civilization!

After all, compared with the sweeper civilization, even if it becomes a fourth-level civilization, human beings are nothing more than a larger ant.

Now it's just the detectors.

Lu Yongchang didn't want to see the battleship of the Sweeper civilization parked in front of his house!

Sit and watch a play?

This is not Lu Yongchang's style of acting.

Lu Yongchang turned his hands away and paced back and forth in the laboratory, thinking about the next countermeasures.

……

The central black hole region of the Milky Way.

Inside a stationary artificial planet.

A message flashed across an inconspicuous light curtain.

[Number: Detector No. 912133165...]

In the next second, a tentacle reached out from a distance.

The tentacles slid across at will, and the light curtain with flashing information disappeared instantly.

"what happened?"

The sound of Sweeper 9527's inquiry came from a distance.

"It's nothing, it's the data report sent back by the detector." The person who turned off the light curtain responded respectfully, "It's just some comparison data that doesn't matter."

Hearing this, Sweeper 9527 nodded slightly in agreement: "It's just a low-level civilization, let the type I artificial intelligence built into the detector handle it by itself."

"Our primary goal now is pastoral civilization."

"According to the data sent back by the mother civilization, four-dimensional space fluctuations have appeared in the Triangulum galaxy bridge area."

"Here they come."
