The planet in front of him was so special that Li Wenyuan couldn't help but pay too much attention to it.

This is a planet completely covered by oceans, with no trace of land visible on its surface.

According to speculation, the average water depth of this planet can reach more than 8,000 meters, and the deepest point is more than 20,000 meters.

And such a planet rich in water resources is located near a black hole. No matter how he looks at it, Li Wenyuan feels that this is something done by humans.

Due to the influence of tidal forces, this ocean planet is setting off huge waves almost all the time.

This time it is really "monstrous". The waves can form thousands of meters high water walls, scraping layer after layer on the surface of the planet.

Such huge waves have reduced the usual habitability here, not to mention the harsh space environment near a black hole.

Strictly speaking, this place is not suitable for any intelligent life to live.

This peculiar "big wave landscape" also led Li Wenyuan to call this special ocean planet a "big wave planet."

After all, ocean planets can give birth to intelligent life. The "First Empire of Turbulence" is a kind of aquatic creature, and their origin is a gentle ocean planet.

However, it is as difficult as climbing to the sky to give birth to intelligent life on such a giant wave planet. The extremely harsh surface environment prevents the possibility of the birth of complex life.

Perhaps only under the deep sea can some special intelligent life appear.

Li Wenyuan was initially very interested in the planet itself. After all, there was too much water here.

Except for the giant wave planet, the other planets in this black hole galaxy have become barren planets without any life due to the harsh space environment.

However, this huge wave planet is obviously similar in size to other planets, but its atmosphere has not dissipated, and the water is firmly locked on the surface of the planet.

Seemingly out of the ordinary, Li Wenyuan felt that humans were experimenting here no matter what.

"...a black hole galaxy that is building a matter decompressor, what kind of experiments are being conducted by the way?" His scientific research spacecraft approached the giant wave planet and launched a large number of drones for reconnaissance.

The environment here only has endless deep seas, and it is much more troublesome to explore than those ordinary planets.

Although UAVs can also conduct deep-sea exploration, their efficiency in the water is always much lower than in the air.

However, in view of the special environment here, Li Wenyuan called Hui Feng over to see if she was interested in this place.

Then, as expected, Gray Feng showed full curiosity.

"A huge wave planet with a 10,000-meter-deep sea? Isn't this an excellent adventure zone?"

The game she is playing recently is "Terror of the Deep" developed by Turbulent First Empire. This group of aquatic creatures understand the ocean much more carefully than ordinary creatures.

Even for today's interstellar civilization, there are no secrets in the ocean anymore, everything can be exploited.

But this interstellar civilization composed of aquatic creatures still retains awe of the ocean. Countless of their works are related to the deep sea and are full of ancient primitive fears. Nowadays, horror stories are popular in various civilizations and have formed a cultural trend.

.

But this is just a little bit of entertainment spice, because these interstellar civilizations do a lot of things like pumping water. Sometimes, even if all the water on a planet is drained, there will be no "terror in the deep sea".

In the interstellar age, the unknown feeling of the universe is even more frightening.

But Gray Feng doesn't want to be taboo. The deep sea adventure is a story she has never thought of before. Maybe in addition to the void of space, the unknown deep sea is also a unique flavor.

So she took the initiative to enter this giant wave planet without even asking Li Wenyuan.

As Gray Wind and a large number of detection drones penetrated deeper, the internal environment of this huge wave planet was gradually revealed before his eyes.

As he expected, there were only some simple microorganisms and algae living on the surface of the planet. Occasionally, slightly more complex creatures came to this area and hurriedly dived down.

The huge tidal force will cause thousands of meters of sea surface to be rolled up and then fall. During this process, no living thing can resist the huge impact of falling directly to the ocean surface from a thousand meters high in the sky.

It's no different than falling directly on a rock surface.

But after leaving the outermost dangerous zone, the species on the Big Wave Planet suddenly became more diverse.

It is difficult for the light from the black hole's accretion disk to penetrate this depth, and the creatures here grow very randomly.

The lack of eyes is almost a necessity, and the body has evolved to adapt to the environment here.

You can see some kind of fish with a streamlined body rushing through here. In order to adapt to the water pressure, its muscles are extremely strong, and its powerful tail allows them to draw a sheet of white foam in the water like an arrow.

They suddenly lost half of their bodies before their food even had time to react, and the other half disappeared into the ocean a few seconds later, leaving only the well-fed predators swimming leisurely.

But this was just one link in the food chain. A tentacle suddenly shot out from the deeper sea, dragging the predator that had just had a feast into the deep sea. Its fate was self-evident.

A complete and stable ecological cycle was formed on this planet, and it was in this area with the most biomass that Li Wenyuan discovered a "deep sea observation station" left here by humans.

"What is that?" In Gray Feng's curious expression, a giant suspended building motionless in the torrent gradually revealed its full shape in the dark ocean.

Its appearance looks like a giant top, and its outer shell is covered with fluorescent material, which becomes the only light source in the lightless deep sea.

It stands to reason that the phototaxis of deep-sea fish would cause the creatures here to swarm, but a sound wave that surrounds this giant building all the time drove away those creatures.

Compared with this very lively area, this place is undoubtedly much deserted.

But this may be what this "deep-sea observatory" needs.

So when Gray Wind and his drone approached here, he also received the human signal from this observation station:

[Warm reminder from "Deep Sea Observation Station No. 003":]

[This is a "fish tank", please do not disturb the ecological environment here, otherwise a poor researcher will lose his research results! 】

"Fish tank?" This special title made Li Wenyuan stunned, and then he understood it immediately.

"...This should be a cultivation area for some kind of experimental materials. I guess the research topic is 'On the evolution of organisms on ocean planets in a black hole environment'..."

In fact, it is quite normal for this kind of thing to appear. Not to mention human beings, even today's interstellar society, due to the rapid development of productivity, many experiments are conducted on a "planet" basis.

The Milky Way is so vast that it cannot always be limited to a small planet.

Many interstellar rich people have bought several desolate planets, built artificial ecological cities on them, captured some natives, and treated them as "gods" to enjoy the feeling of worship.

There are also some daring mad scientists who quietly invade the indigenous planets for some sociological research, stir up internal turmoil, and then expand the experimental samples.

These are all actions that can be achieved in the interstellar era, so it is not impossible for humans of that era to build such a "planetary fish tank".

But what Li Wenyuan expected was that in addition to human signals, he also detected other signals.

This kind of signal is completely different from the one commonly used by humans, but it is full of rules. It is presumed that it is also a signal sent by an intelligent creature.

After translating, Li Wenyuan became more and more curious about the situation of the "Deep Sea Observation Station".

It was a distress signal: "——We have been invaded by the enemy, please support us as soon as possible!"
