"Black hole galaxies? What does that mean? Lin Xu was surprised.

Then Ying's confused explanation, Lin Xu understood what was going on.

The so-called black hole galaxy naturally cannot mean that the galaxy has become a black hole.

It's about the galaxy, like a black hole, where nothing can be entered or exited.

Any warship of civilization that entered that system never returned.

Even the higher civilization that the Malian knew to sell the Malian curvature engine had sent warships into the Black Hole galaxy a thousand years ago.

As a result, the warship of the higher civilization named Hono also did not return.

Even from the battleship into the black hole galaxy, there was no more news, not a single quantum communication signal.

For this reason, the Hono High Civilization also sent people to investigate and study.

It turned out that the entire black hole galaxy was in an inexplicable state of lockdown, and the probes could enter, but could not leave.

Even the signal from the detector could not be transmitted.

Even if the optical telescope can clearly see that the detector is there, and even if it sends out an action command, the detector can still receive it and act according to the command.

But the signal from the detector just can't be transmitted, and the detector itself can't leave.

This strange phenomenon aroused great curiosity among the Hono civilization at that time.

However, immediately after that, a war broke out between the Hono High Civilization and the Misai High Civilization because of half a unit of Chaos Elemental Energy, and the Hono Civilization's research on the black hole galaxy was suspended.

As a result, the existence of black hole galaxies gradually spread among nearby civilizations within a radius of more than 100 light-years.

During this period, there were also some civilizations that came to check out out curiosity, but even the higher civilizations did not study anything, so everyone just watched from a distance and left.

The nearby area of more than 100 light years basically belongs to the sphere of influence of the Heno High Civilization, although it belongs to a relatively remote area.

But it is rare for other advanced civilizations to set foot in it.

Therefore, when the Hono High Civilization was busy with war, naturally there were no other High Civilizations to study the Black Hole Galaxy.

Even if the war was over later, the Hono High Civilization might have forgotten about this place and did not study it again.

Until the advent of the Earth.

"So, what did humans do in that galaxy that became a black hole galaxy?" Lin Xu could only guess so.

Whoever let this go along the way, human beings are building a magical world to live, and they are doing experiments to blow up the planet.

What kind of black hole galaxy is this, and it happens to be the galaxy where mankind is preparing to build a large-scale antimatter annihilation energy confinement collection device, who else could it be if it wasn't done by humans?

In short, whether it was Lin Xu guessed or not, we can only know by looking at it.

Anyway, I definitely have to go, after all, the antimatter reactor, Lin Xu will never give up.

And without an energy-constrained harvesting device, an antimatter reactor cannot be built.

Even if there were no such reasons, just because humans had been there 10,000 years ago, Lin Xu had to go and see it.

In short, Lin Xu was ready to stop and was about to set off.

Before leaving, Lin Xu released the fleet of the Republic of Mali and all the soldiers.

After all, the two sides were not hostile from the beginning, and Lin Xu even felt that he was quite embarrassed to rush into other people's trading sites and rob other people's trading things.

But if he robbed it, he grabbed it, and he didn't plan to pay it back.

On the contrary, the upper and lower people of the fleet of the Republic of Mali did not resent Lin Xu at all, and were even grateful.

After all, he privately traded Chaos Yuan Energy on his side, and was caught by other people's high civilizations, and it was already good that he didn't go to his home planet to ask for the guilt, and even released himself in the end, he was really a good person, there are not many such good high civilizations.

What's it called, Earth civilization, right? Well, you must remember in the future that the earth civilization is a good civilization.

As for the temporary caravan, that's a different treatment.

Lin Xu first handed over the captives from the low-level civilizations in the temporary caravan that had not yet broken out of the home planet to the commander of the Republic of Mali, and asked them to help send these poor people back as much as possible.

Commander Kalincha agreed.

Among them, there are even many women who have been devastated and unshaped.

It's all interstellar civilizations, is it difficult to get some robots that look exactly like real people? Is it so funny to mistreat captives, not to mention captives of different races, different looks, and potentially very different aesthetics?

How did you do it?

Anyway, if Lin Xu was faced with a female orc, he would definitely not be able to do it.

Then Lin Xu handed over the members of the caravan to the commander of the Republic of Mali, but this time it was not for him to take care of.

Instead, he let him execute the garbage.

Lin Xu didn't want to get his hands dirty, so he let others do it for him.

Kalincha naturally agreed.

Anyway, I will listen to whatever the master of high civilization says.

In this way, the matter was settled, and I watched as the ten warships of the Republic of Mali slowly moved away, gradually increasing their speed to twice the speed of light, and disappearing into the universe.

The Earth also turned slightly, heading towards a black hole galaxy five light-years away.

Five light years, about two and a half years at the speed of the Earth.

The time was not long or short, and after Lin Xu hesitated, he still chose to sleep.

Soon, two and a half years passed, and the time came to set sail in 10993, when Lin Xu was awakened by Miss Qiu from the dormant warehouse.

Black hole galaxies are just around the corner.

It is still a familiar courtyard, Lin Xu is sitting under the big tree in the courtyard, and in front of him is a holographic projection, the whole picture of the so-called black hole galaxy.

Looking beyond galaxies with optical telescopes, you can see that black hole galaxies are very common galaxies.

A star, and ten planets orbiting the star.

"Master, do you want to send the self-discipline machine to investigate immediately?" Qiming's voice rang out.

"Let's do it." Lin Xu nodded.

As a result, a large number of autonomous mechanical aggregates around the earth immediately surged.

An autonomous mechanical aggregate of millions of pillars is being built, and hundreds of them are being spun off and sent to space under the action of anti-gravity devices.

Immediately in low-earth orbit, a curvature engine with a diameter of about a kilometer was received.

Immediately afterward, hundreds of autonomous mechanical aggregates enveloped the curvature engine, which disassembled and reassembled in the blink of an eye.

A ship more than 3,000 meters long appeared in low-earth orbit.

Immediately, the curvature engine in the ship was activated, and the ship reached a tenth of the speed of light at a very fast speed, heading towards the target galaxy.

At most, within a few minutes, the ship has already disappeared into the interior of the target system.

"Quantum communication is normal, the spatial perception radar is activated, the return signal can be received, and everything is normal." Qiming reported the results of the probe.

However, it is precisely because everything is normal that it is the most abnormal.

"Didn't you say that this is a black hole galaxy and the signal can't be transmitted?"

No one could answer Lin Xu's question.

After hesitating, Lin Xu still decided to be reckless.

"Let's go, let's go in and have a look."

So, the Earth started and sailed towards the so-called black hole galaxy.
