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

It is already a great reward for the other party to be willing to speak.

But the last sentence made his eyes widen!

revenge? !

The other party actually mentioned revenge? !

Could it be that……

Lv Yongchang breathed slightly short of breath, and responded quickly after some consideration.

[You just mentioned revenge? 】

[If you are as strong as you, will you be injured? 】

The 1420 MHz signal flashes rapidly.

[Hehe... I'm just a seventh-level civilization. 】

Lu Yongchang's eyes changed quickly, and he asked again.

[In the Milky Way, are there many civilizations above level seven? 】

【How did you get hurt? 】

But this time, nothing happened to the 1420 MHz signal.

This two-dimensional creature named [Hua] suddenly became "cold" and never responded to the messages sent by humans.

……

After half an hour.

Looking at the Ross 154 image sent back by the detector, and then looking at the "chat record" stuck at the last sentence, Lu Yongchang frowned and sighed softly.

"Professor, what should we do now?"

Cao Liangcai's voice came from the side: "Go? Or stay?"

Lu Yongchang thought for a moment, then slowly shook his head.

"Can't go."

"At least, we can't act rashly before speaking to the other side."

"Let's stay where the fleet is, and all projects are suspended."

"Zero, keep monitoring Ross 154... testing." Thinking of the terrifying existence in Ross 154, Lu Yongchang swallowed the words abruptly, and changed it to another way of saying, "If the other party sends another information, notify me immediately!"

Afterwards, he reached out and rubbed his stiff face, and said in a deep voice.

"Next, it's time for us to sort out the information obtained from this exchange."

……

"first."

"The other party is a two-dimensional creature, there is no doubt about it." Lu Yongchang stretched out his hand and called up several data sent back by the detector, "No matter what detection method we use, we can't detect the 'thickness' of the other party."

"Of course, it may also be because our instruments are too backward."

Speaking of this, Lu Yongchang shrugged: "I personally prefer the former."

"In addition, it can be found after slow-motion processing of the picture."

"The other party can easily contract and extend their own body."

"As to why it doesn't wrap the entire star, my guess is that it takes a lot of energy to do that."

"At least, for the current it, it is an act that is not worth the candle."

"At the end of the conversation, the other party mentioned the word revenge. Combined with the above conjectures, we have reason to suspect that it is in a state of injury at the moment."

"Also, it needs Ross 154 as its energy source."

"This is also the reason why Ross 154 was so bright."

"Anyone have an issue with that?"

After speaking, Lu Yongchang scanned the crowd.

Seeing that no one objected, he said again: "Okay, on this basis, let's analyze the other party's words."

"The other party claims to be a seventh-level civilization, a two-dimensional creature, and was born in the Triangulum galaxy 50 billion years ago."

Lu Yongchang's voice paused for a moment, and he said again: "The Triangulum galaxy, the third largest galaxy in the local galaxy group, is about 295 million light-years away from the Milky Way."

"We assume that the other party has curvature navigation technology, which can greatly shorten this long journey."

"However, how did the other party cross this almost empty space?"

"During the voyage, the other party hardly received any material supplements."

"Then why did it spend so much energy to come to the Milky Way, and then be beaten up by the so-called higher civilization?"

He Bilin in the distance suddenly raised his right hand.

Lu Yongchang was taken aback for a moment, then nodded and said, "Say it."

He Bilin straightened his expression and said seriously: "Professor, I need to correct something."

"It's not impossible to get material supplements during the inter-galaxy voyage."

Hearing this, Lu Yongchang raised his eyebrows: "Oh?"

"Tell me in detail."

He Bilin organized some words in his heart, and said again: "According to our observations, there is a galaxy bridge between the Triangulum Galaxy and the Andromeda Galaxy."

"This galaxy bridge is mainly composed of neutral hydrogen."

"According to the current observation data, the length of this galaxy bridge has reached 78.2 light-years."

"By analogy, we have reason to suspect that there is also such a structure between the Triangulum galaxy and the Milky Way."

"It's just that we haven't discovered this galaxy bridge yet."

Lu Yongchang nodded thoughtfully.

"If this is the case, it can be explained."

"only……"

"Until now, we have not been able to analyze the purpose of this behavior from the other party's words, nor the authenticity of his words."

Lu Yongchang sighed softly: "At present, there are no loopholes in the other party's words."

Then he shrugged.

"However, it's not a big problem."

"After all, we can't mess with even a seriously injured seventh-level civilization."

Hearing this, Fang Xu and others laughed wryly.

It hurts, but it's true.

The current human civilization can only live in the shadow of the other party with trepidation, praying that the other party will forgive.

……

Time passed little by little.

An hour, a day, a week...

The 1420 MHz signal seems to have disappeared and never appeared in the world of human civilization again.

It's as if... the seventh-level civilization in Ross 154 quietly left.

until a month later.

Lu Yongchang sat in the office of [Earth], frowning and looking at the holographic projection in front of him.

On the projection, it is the image of Ross 154 from the interstellar probe.

Looking at the dark red light emitted by this red dwarf star, Lu Yongchang sighed softly.

"I don't know what the seventh-level civilization means..."

He muttered, "Our development has been stagnant for a whole month."

Yes, human civilization has been living in the shadows for a whole month since the two-dimensional creature [painting] stopped talking.

Neither go nor stay.

"Yes."

Fang Xu's voice came from across the desk: "Ghost knows what the concept of time is for this two-dimensional creature."

"If the 50 billion years it said is true, I'm afraid the other party will be tens of thousands of years in a daze."

"If this is the case... human civilization will die here sooner or later."

Lu Yongchang pursed his lips, his eyes revealing a hint of thought.

"Wait another month."

He made up his mind.

"A month later, we will send another inquiry message to the other party."

"If there is no response, then we are ready to leave this star system."

"The materials stored in the past two years should be enough to support us to make another voyage."

Fang Xu pondered for a moment, nodded and said: "That's the only way."

"I hope this seventh-level civilization doesn't care about our actions."

In the office, it fell into silence again.

"Drip-drip-drip-"

After a month, the sharp sirens once again filled Lu Yongchang's ears.

"Professor, an abnormal signal has been detected at 1420 MHz, and the source of the signal is Ross 154!"

"Here we come!" Lv Yongchang's face turned serious, he reached out and unfastened the electromagnetic adsorption device on the seat, and got up and said.

"Zero, call all personnel, and assemble at the command center!"

……

[Interesting little guys, let's chat again. 】

[Calculating the time, I haven't talked to little guys like you for more than 40 billion years. 】

Looking at the two lines of text in front of him, Lu Yongchang took a deep breath.

"Talk to it!"

"This is our only choice! It is also our only role for him!"

As he spoke, he considered for a moment, reached out and pressed the holographic image in front of him.

[Hello, dear seventh-level civilization, we are very willing to be a listener. 】

A signal came quickly from the direction of Ross 154.

【listener? 】

[Hehe... I never thought that I, a dignified two-dimensional creature, would be reduced to telling stories for a second-level civilization! 】

[It's going to be known by those pastoralists... What a shame! 】

From the text message sent by the two-dimensional creature, one can clearly feel the unwillingness in its heart.

A gleam flashed in Lu Yongchang's eyes.

He quickly captured the key words in the words of [painting].

【Dear painting, what do you mean by pastoralism?A faction in the universe? 】

The two-dimensional creature [painting] was silent for a while, as if thinking about something.

A few minutes later, the lines of text appeared in front of everyone again.
