Technological supremacy starts with acquiring alien spaceships

[Generally, these cosmic voids, areas with extremely low celestial body density, or even void regions without any celestial bodies, are rarely formed naturally. In our 7th-level civilization, when we discovered such situations in our universe, there were always powerful interstellar civilizations present. Only they have the ability to clear an area. But in this star field where we are, I haven't detected any clues of advanced civilizations, which is very abnormal!]

Chen Yu frowned in thought.

Now that his brain development has reached 25%, he can quickly analyze and think about many things.

"So, if there was once a super powerful interstellar civilization here, and for some reason, they all left, leaving only the Black God Star?"

[That's possible, but the probability is relatively low, because a powerful technological civilization wouldn't disappear so completely. Within this area of 80 million light-years in diameter, it's impossible for nothing to be left behind. Even if it's just cosmic dust, there should be remnants of spaceships!]

This was simply too strange. Could it be that an advanced civilization once existed on this ancient planet?

And cleared the surrounding area?

To be able to clear the surrounding 80 million light-year star field, according to the AI, would require at least a 6th-level civilization.

Generally, a 6th-level civilization in the universe is already considered a super powerful civilization.

In Chen Yu's Earth, the Milky Way, the Virgo Supercluster, and even the Laniakea Supercluster, they could become the dominant planet.

And such a civilization would never hide in a void region, living a low-profile life.

This planet probably still holds secrets.

This was Chen Yu's guess.

In the Millennium Falcon's command room, Chen Yu asked the AI:

"AI, is our gravity bomb ready?"

[Captain, during these few days of travel, I have already created one, sufficient to destroy this rocky planet with a diameter of over 60,000 kilometers.]

"Don't rush. I always feel that this void region, why there are no other planets, is related to this Black God Star. It may hold the answer we are looking for!"

[Captain, I have the same thought!]

"Since you also want to know the secrets within, then we'll continue to explore the planet. We'll re-enter the huge cave. We were originally going to send the gravity bomb into it, so this time we'll go in for a deeper exploration!"

[Okay, Captain!]

The so-called cosmic exploration is about exploring. For Chen Yu, whose brain development exceeds 25%, at this moment.

The satisfaction of obtaining the truth is higher than creating any high-tech weapon.

This was a strange phenomenon that even the AI couldn't understand. Chen Yu was very curious!

The Millennium Falcon once again arrived at that familiar location.

Above the huge cave, the spaceship hovered quietly.

Lights lit up on the spaceship, illuminating the huge pit with a diameter of several kilometers.

Looking down, it was like an endless abyss. Even though the lights on the Millennium Falcon were very bright, like a small sun.

It couldn't illuminate the bottom of the pit, and the surroundings of the giant pit remained silent.

Not a single crystal monster could be seen, completely opposite to the densely packed scene from before.

"AI, logically speaking, after we left, those black behemoths would release those crystal ghost things. This is where they absorb radiation. Why are there no crystal monsters here? Did they know we would come back, so they abandoned this place?"
