"only……"

"Until now, we have not been able to analyze the purpose of the other party's words for doing this, nor can we analyze the authenticity of their words."

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

Then, he shrugged.

"However, the problem is not big."

"After all, even a seriously injured level seven civilization is not something we can mess with."

Hearing this, Fang Xu and others smiled bitterly.

Although the words are hurtful, they are indeed right.

The current human civilization can only live in the shadow of the other party with fear and pray that the other party can be separated.

...

Time passes by bit by bit.

One hour, one day, one week...

The 1420 MHz signal seemed to disappear and never appeared in the world of human civilization again.

It was like... the seventh-level civilization in Ross 154 quietly left.

Until one month later.

Lu Yongchang sat in the office of Earth, frowned and looked at the holographic projection in front of him.

On the projection, there is a Rose 154 image sent from the interstellar probe.

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

"I don't know what this level seven civilization means..."

He murmured to himself: "Our development has been stagnant for a whole month."

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

It’s not right to leave, nor is it stay.

"yes."

Fang Xu's voice came from opposite the desk: "God knows what the concept of time of this two-dimensional creature is like."

"If the five billion years it said was true, I'm afraid the other party would be tens of thousands of years in a daze."

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

Lu Yongchang pursed his lips, and a hint of contemplation appeared in his eyes.

"Should another month."

He made up his mind.

"After a month, we will send inquiry information to the other party."

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

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

Fang Xu pondered for a moment, nodded and said, "I have to do this."

"I hope this level seven civilization will not care about our actions."

In the office, it fell into silence again.

"Drip—drip—drip—drip—drip—drip—drip”

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

"Professor, an abnormal signal was detected at 1420 MHz, and the source of the signal is Rose 154!"

"Here you come!" Lu Yongchang's face sterned, he reached out and unbuttoned the electromagnetic adsorption device on the seat, and stood up and said.

"Zero, call all the personnel and gather the command center!"

...

【Interesting little guys, let’s chat again.】

[Counting the time, I haven't talked to a little guy like you for more than 4 billion years.]

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

"Talk with it!"

"This is our only choice! It is also our only effect on him!"

As he said that, he thought for a moment and reached out to press the holographic image in front of him.

[Hello, Dear Level 7 civilization, we are very willing to be a listener.]

The signal was quickly transmitted from Ross 154 direction.

【Listen?】

[Haha... I didn't expect that my two-dimensional creature would fall to telling stories to a second-level civilization!]

[That's what the pastoral guys know about this... It's so embarrassing!]

From the text information sent by two-dimensional creatures, you can clearly feel the unwillingness in your heart.

A glimmer flashed in Lu Yongchang's eyes.

He quickly captured the keywords in the discourse of [painting].

[Dear Painting, what is the pastoral school you are talking about? Is it a faction in the universe?]

Two-dimensional creatures [painting] were silent for a while, as if they were considering something.

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

[Forget it, this thing is not a secret, and it is not a big deal to talk to you.]

[In this universe, higher civilizations are mainly divided into three factions.]

【First, the cleaner.】

[Second, pastoralism.]

[Third, neutral faction.]

Lu Yongchang opened his eyes wide and subconsciously slowed down his breathing a little.

This kind of knowledge is not something that humans can obtain behind closed doors!

By understanding the factions in the universe, humans can have a basic understanding of the way various civilizations in the universe get along.

The dark forest system derived on Earth is obviously not very suitable for the seventh-level civilization in front of you.

While Lu Yongchang was thinking, new words were still continuously presented in the holographic projection.

【Let’s talk about the cleaner first.】

【Composed of a group of crazy level 8 civilizations.】

[In order to break through the so-called ninth-level civilization, they have prepared for billions of years.]

[In the past billions of years, they have made a ring cosmic particle collider.]

Lu Yongchang gasped suddenly.

Ring Universe Particle Collider!

What a particle collision device this is!

Not only Lü Yongchang, but also the [Earth] was in full swing!

The noisy talk continued in the command center!

Particle collision device has one feature.

The larger the body size, the more energy it consumes for acceleration, and the speed of the accelerated particles is closer to the speed of light.

99% speed of light, 99.9% speed of light, 99.99% speed of light...

It seems that there is only one decimal difference, but the energy levels contained in it are like a huge difference!

Every 9 increase means that the energy contained in the particles increases by an order of magnitude.

According to the special theory of relativity.

When the number of 9 after the decimal point reaches 142, the energy contained in particles is equivalent to the total energy of the annihilation of the Milky Way!

When the number of 9 after the decimal point reaches 182, the energy contained in particles is equivalent to the total energy of observable universe annihilation!

When the number of decimal points 9 reaches...

Lu Yongchang shivered slightly.

He couldn't imagine how many 9 can be added to the so-called ring-cosmic particle collider after the decimal point!

[This group of madmen are actually preparing to use the entire universe as fuel to charge the ring universe particle collider!]

[They believe that doing so can reproduce the scenes during the Big Bang and recreate a new universe!]

[Then, take this opportunity to master the technology to be promoted to level 9 civilization!]

[Crazy people! A bunch of mad people!]

Speaking of this, the tone of the two-dimensional creature [painting] is obviously much more irritable.

Even the Ross 154 in the distance seemed to be lit and dark.

Lu Yongchang stared at the holographic projection in front of him in a daze.

He swallowed and said carefully.
Chapter completed!
