The holographic screen was blank.

Only the deep blue background screen was projected in front of the academicians.

"It's silent?"

Lu Yongchang's lips twitched slightly, his eyes filled with helplessness: "This thing... it can't only be used by Level 5 civilizations, right?"

"Very likely."

The voice of Academician Lin Zile from the Sociology Academy came from the side: "From the behavior of the [Silicon Ray Civilization], it can be seen that silicon-based civilizations have their own communication frequency bands."

"Extend this reasonably."

“There should also be communication frequencies between civilizations of different levels.”

"To a Level 6 civilization, the information emitted by a Level 5 civilization is actually just noise."

"This is likely the main reason for this phenomenon."

"Of course, there might be another reason." Lin Zile shrugged as he spoke. "There are too many Level 5 civilizations around here."

Upon hearing this, Lü Yongchang was momentarily stunned.

Under normal circumstances, the further you go into a galaxy, the greater the probability of encountering an advanced civilization—this is closely related to the material density of the galaxy.

Based on the material density-civilization level model established by human civilization in the Milky Way, this resource-rich land near the interior of the Andromeda Galaxy should be more in line with the development needs of a Type VI civilization.

When he turned his gaze to the star map, he suddenly realized something.

The AGBH-01 and AGBH-02 binary black hole regions.

That location is in a relatively resource-poor region of the Andromeda Galaxy, which is theoretically the settlement of a Type 5 civilization.

"You mean... the Type 5 civilization that originally lived near the AGBH-01 and AGBH-02 binary black hole regions has migrated to the surrounding star systems?"

Lin Zile nodded and quickly drew several areas on the holographic projection in front of him.

"Based on the effective range of the five-level civilization's tachyon communication, we can make a rough guess."

"As long as the fleet travels more than 30,000 light-years towards the target area, we will leave these noises from a Type 5 civilization behind."

"If those Level 6 civilizations are really using this frequency band, perhaps we can receive their messages from there."

"Of course, I am personally pessimistic about this."

"Compared to a Level 5 civilization, a Level 6 civilization is qualitatively different. They might not be as... well, talkative as a Level 5 civilization."

Lu Yongchang's expression suddenly became somewhat strange.

"Well... it's hard to say."

With that, he waved his hand helplessly and shut down the giant holographic projection in front of him: "Zero, continue receiving tachyon signals."

"Remind me immediately when a tachyon broadcast of sufficient strength is detected."

Fortunately, receiving tachyon information does not require much energy, and human civilization can completely "invisibly" receive all the information along the way.

...

In Earth's history, the region between the AGBH-01 and AGBH-02 binary black holes is less than 50,000 light-years away.

The region of the black hole at the center of Andromeda.

Using the logo of the Silicon Alliance, the human fleet is brazenly and recklessly traveling through the Andromeda Galaxy.

At first, Lü Yongchang actually had some hesitation.

That is, after all, the center of the river system with the highest material density.

Putting aside other advanced civilizations, the Cleaners civilization is definitely here!

In the original plan, the human fleet needed to bypass this "dangerous" area... until the tachyon broadcast receiver received the first message from another advanced civilization.

[Little guy from the Silicon-based Alliance, this is the territory of the Level 7 Tinka Civilization.]

Upon seeing this message, Lü Yongchang instantly felt half of his body go numb.

A level seven civilization?!

When did the human fleet intrude into the home of a Level 7 civilization?!

Before Lü Yongchang could finish editing his apology message, another broadcast came on.

[Don't be nervous. The Tinka civilization belongs to the neutral faction. Please give my regards to Silicon Ray.]

[By the way, could you ask them when they plan to return the three Blue Giants they used on my end last time?]

Lu Yongchang suddenly felt numbness on the other half of his body.

It turns out this silicon ray civilization is a repeat offender!

At the same time, he also experienced firsthand the benefits of joining the silicon-based alliance for the first time.

There are "familiar faces" everywhere!

For human civilization... no, for the Enroget civilization, which wanted to quietly develop while the situation was in disarray, wouldn't this be paradise?!

After a brief exchange with the Tinka civilization, Lü Yongchang gained a deeper understanding of the neutral faction.

In terms of top-tier combat power, the neutral faction cannot compete with the Cleaners and the Pastoral Faction.

but……

The sheer number of neutral advanced civilizations is overwhelming!

Not only is the base large, but they are all mid-to-high-end combat forces!

Furthermore, the neutral faction is a relatively loosely organized mutual aid group...

This has created a rather bizarre situation.

Whether they are pastoralists or cleaners, neither side wants to offend the neutral civilization for the sake of their own plans and intentions.

then……

The fleet directly changed its original detour plan—taking a "shortcut"—passing through the central black hole region of the Andromeda Galaxy and heading towards the target area!

The Academy of Sciences thus witnessed the charm of "big places".

Along the way, the human fleet's tachyon broadcast receiver would receive a message from time to time—almost all of these messages came from neutral level 7 civilizations.

This is a spectacle that is simply impossible to see within the Milky Way!

Based on this information, the Chinese Academy of Sciences has also preliminarily drawn a map of the power distribution in the central region of the Andromeda Galaxy.

Neutral Level 7 civilizations are scattered around the central black hole in Andromeda.

Of course, in addition to these known spheres of influence, there are also large areas of unknown star fields in and around the central black hole.

It's conceivable that those areas likely belonged to the territories of the Cleaners civilization and its affiliated civilizations!

The Cleaners, or rather the Cleaners' affiliated civilization, did not react to the intrusion of the human fleet.

then……

The human fleet sailed safely and brazenly into the region of the central black hole in Andromeda.

Looking at the silvery-white planetary fortresses near the black hole, and the massive technological creations comparable to blue giant stars, Lü Yongchang subconsciously held his breath.

This is the Andromeda branch of the Cleaners.

[Enroget Civilization, this area belongs to the Cleaners Civilization, please leave immediately!]

...

The Cleaners Andromeda Branch.

【9436】Looking at the scene on the light screen, his skin turned pale and the tentacles on both sides of his body trembled slightly.

That's going too far!

The Enrogett civilization has gone too far!

They've brazenly come to my doorstep!

but……

Seeing the clearly visible markings on the surface of those warships, [9436] issued a warning message and silently shut down the light screen in front of it.

Out of sight, out of mind.

It cannot afford the consequences of taking action against neutral civilizations.
