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

Ross 154 is a young star with a very high outburst frequency and a huge source of X-rays.

Therefore, sending and receiving radio signals has become an extremely difficult job.

In order to ensure the successful sending and receiving of signals, this communication satellite was developed by Cao Liangcai himself.

As for why so much effort was put into making this satellite...

Communication latency is too high.

Although the distance between Ross 154 and Ross 2 is only 580 million kilometers, for electromagnetic wave communication, it takes 38.6 seconds to go back and forth!

Such a huge communication delay is obviously unacceptable.

……

【Painting】The communication satellite located "nearby" was discovered.

In the next second, his response was sent directly to this small satellite.

[The four-dimensional weapon of the Sweeper Branch has caused great damage to my core. 】

[For hundreds of years, I have been trying to repair the core. 】

[However, to no avail. 】

Lu Yongchang's breathing suddenly became rapid.

Not only him, Zhao Zijie on the [Earth] also became short of breath.

Not fear, but...greed!

A seventh-level two-dimensional creature that is about to die...

This temptation is extremely great!

If you can get a part of his body...

Perhaps, human civilization can use this to pry into the mysteries of dimensions!

Lu Yongchang took a deep breath, suppressed the distracting thoughts in his heart, and carefully edited a line of information.

[Excuse me, what can we help you with? 】

Although it is a bit humble, it is also impossible.

After all, the other party is not "dead".

He didn't want to touch the mold of a "dying person"!

[Painting]'s response quickly appeared in front of everyone.

[Little guys, can you help me deliver a message to the pastoralists? 】

[As a reward, I can tell you the way to enter the third-level civilization. 】

Lu Yongchang's expression suddenly became strange.

fraudulent.

This was the first thought that flashed through his mind.

"Is something wrong?" Fang Xu frowned and murmured in a low voice, "A seventh-level civilization needs us to send information?"

"It doesn't make sense, does it?"

Perhaps aware of the hesitation of human civilization, [Hua] sent several messages again.

[Perhaps you are doubting my motives, but please believe me, I have no malicious intentions. 】

【Currently, the Galaxy Sweeper branch is trying its best to search for my traces. Any movement by me will lead to disaster. 】

Lu Yongchang frowned even deeper.

"It's inconsistent." He stood up from the chair, pacing back and forth with his hands behind his back, "Since he is already on his deathbed, why should he be afraid of this so-called sweeper civilization?"

Fang Xu didn't speak, just stared at the holographic projection directly in front of him.

Another new line of text appeared in front of everyone.

[My death is a trivial matter, but the failure of information transmission is a major event! 】

【So, I ask you all to do me a small favor. 】

Seeing this, Lu Yongchang raised his eyebrows suddenly.

"interesting."

"That's a decent reason."

"It's just..." Lu Yongchang smiled and shook his head, "Did he overestimate our abilities?"

As he spoke, he swiped his finger and edited a message.

[Dear [Hua], we are just a small second-level civilization, and may not have enough ability to help you. 】

……

Inside Ross 154.

The thick gray "drawing paper" trembled violently.

It seems that there is some dissatisfaction with the response of human civilization.

But soon, "Drawing Paper" regained its composure, and once again sent a message to the satellite around it.

……

[It doesn't take much ability from you! 】

[When I die, I will seal up a part of the core substance. 】

[The sweepers cannot detect its existence, but for the idyllic dimensional life, this is an extremely conspicuous signal beacon, you don’t need to go to them, if they reach the Milky Way, they will go to you! 】

[In order to show my sincerity, I can first tell you how to advance to the third level of civilization. 】

[Protective shield technology is the symbol technology of the third-level civilization. 】

[As for how to break through this technology, after you agree, I will naturally tell you...]

[Hurry up and make a decision, my time is running out. 】

……

Looking at the words constantly brushed out in front of him, Lv Yongchang suddenly suffocated his breath.

According to the cursor in the technology tree system, the other party did tell the truth!

The key technology to break through the third-level civilization is indeed the shield technology.

but……

He doesn't think that the technology tree system can't help him solve this problem.

Perhaps because human civilization has not responded for a long time, [Hua] sent messages more and more frequently.

[Human civilization, what are you worried about? ! 】

【Trust me, I have no malicious intentions! 】

[Grand unified theory!Antimatter technology!Whatever you want, the Pastoral School can satisfy you! 】

[I can't hold it anymore, please respond to me immediately! 】

"Professor, there is something abnormal on the surface of Ross 154."

As Zero's voice sounded, a holographic image unfolded in front of everyone.

On the surface of the dark red Ross 154, a gray "painting" appeared again.

Different from the last time, this time, the surface of the "picture scroll" is no longer smooth, and substances similar to "folds" appear on its edges.

It's like... a flat picture scroll has been crumpled by someone.

Chapter 343 The Two-Dimensional Detector

The vision on Ross 154 made everyone stunned.

"This... what's the situation?"

Fang Xu muttered to himself: "Is this the death process of a two-dimensional creature?"

Incomprehensible.

Lu Yongchang frowned, stretched out his hand and flicked it twice in the air.

The holographic projection screen is instantly enlarged.

The camera focuses on the edge of the gray "scroll".

The fine and dense folds continue to increase.

It looks... like a flat "picture scroll" is constantly being squeezed by the outside world.

"Zero, call out the real-time detection data of the detector." Lu Yongchang seemed to have thought of something, and suddenly said, "Can you detect the thickness?"

"The data is abnormal."

Zero's response made Lu Yongchang's frown deepen.

[Human civilization, have you considered it clearly? ! 】

[My time is running out! ! 】

The information of [painting] appeared in front of everyone again.

You can clearly feel the other party's anxiety and uneasiness between the lines.

but……

He still can't believe the other side.

"Yongchang?"

Hearing Fang Xu's suspicious call, he shook his head slowly: "No hurry, just wait!"

As soon as the words fell, a piercing alarm sounded in the quiet command center!

"Warning! Warning!"

"No. 1 detector signal disappears!"

The red warning lights kept flashing, stimulating the fragile nerves of all scientific researchers.

For a while, the atmosphere in the ground command center became more and more tense!

In the "Earth" far away in the synchronous orbit, Zhao Zijie also stared at the several holographic projections in front of him with a pale face.

"Professor, do you need an evacuation order?"

Zhao Zijie's voice also rang through the communication channel of the ground command center.

"hold on!"

Lu Yongchang's face changed slightly, and he stopped Zhao Zijie's actions: "You can't act rashly!"

"If the other party regards it as provocation or resistance... what will greet us will only be death!"

While speaking, his brain was running fast.

"Zero, call up the records of the other two detectors to see if there is anything captured!"

"There are also optical telescopes equipped by the fleet, and all records will be screened!"

"I want to know what happened just now!"

……

The moment the voice fell.

The huge holographic image directly in front of the ground command center suddenly split into countless fine interfaces.

If you look closely, each finely divided interface is a separate holographic picture.

These pictures come from independent optical telescopes orbiting Ross 154.

These finely divided interfaces rapidly decrease at a rate visible to the naked eye.

Soon, there were only four holographic images left in front of everyone.
