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

It is a planet completely covered in oceans, and there is not a single trace of land on its surface.

It is speculated that the average water depth of this planet can reach more than 8,000 meters, and the deepest depth is more than 20,000 meters.

And such a planet rich in water resources is located near a black hole, no matter how you look at it, Li Wenyuan feels that this is the work of human beings.

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

This time it was really "monstrous", and the waves could form a thousand-meter-high wall of water, scraping layer after layer on the surface of the planet.

Such a large wave has made it less habitable, not to mention the harsh space environment near a black hole.

Strictly speaking, it is not suitable for any intelligent life.

And this peculiar "giant wave landscape" also made Li Wenyuan call this special ocean planet "giant wave planet".

After all, ocean planets can give birth to intelligent life, and the "First Turbulent Empire" is an 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 this giant wave planet, and the too harsh surface environment prevents the possibility of complex life from being born.

Perhaps it is only under the deep sea that some special intelligent life can emerge.

Li Wenyuan was very interested in the planet itself at first, after all, there was too much water here.

Except for this giant wave planet, the rest of the planets in this black hole galaxy have become barren planets due to the harsh space environment, and there is no life.

However, the size of this giant wave planet is about the same size as other planets, but its atmosphere has not dissipated, and the moisture is firmly locked on the surface of the planet.

It seems to be a different situation, Li Wenyuan thinks that no matter how he thinks, it is what humans are experimenting with here.

“…… A black hole galaxy with a matter decompressor, by the way, what experiments are being carried out? His research ship approached the planet Great Waves and flew a large number of drones to reconnoitre.

The environment here is nothing but the endless deep sea, which is much more difficult to explore than ordinary planets.

Although drones can also be used for deep-sea exploration, they are much less efficient in the water than in the air.

However, in view of the special environment here, Li Wenyuan called Gray Wind over to see if she was interested here.

Then, to his surprise, Grey Wind showed great curiosity.

"A giant wave planet with a depth of 10,000 meters? Isn't this a great place to adventure? ”

The most recent game she's been playing is Deep Sea Terror developed by the First Turbulent Empire, a group of aquatic creatures who know much more about the ocean than the average human.

Even though for the current interstellar civilization, there are no secrets in the ocean anymore, everything can be used.

But this interstellar civilization composed of aquatic creatures still retains a reverence for the ocean, and their countless works are related to the deep sea, full of ancient primitive fears, which are now popular in various civilizations in the era of horror stories, forming a cultural trend.

But this is just a little entertainment spice, because these interstellar civilizations have done a lot of pumping water, and sometimes there is no "horror of the deep sea" when all the water on a planet is drained.

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

But Grey Wind is not taboo to think about, the adventure of the deep sea is a story she has never thought of, maybe in addition to the empty space, the unknown deep sea is also a unique flavoring.

So she didn't even need Li Wenyuan's inquiry, she took the initiative to enter this giant wave planet.

And with the gray wind and a large number of detection drones deepening, the internal environment of this giant wave planet is gradually revealed in front of his eyes.

As he expected, there were only a few simple microorganisms and algae living on the surface of the planet, and occasionally a slightly complex creature came to this area and quickly dived in a hurry.

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

It's no different from falling straight on a rock face.

But out of the most superficial danger zone, the species of the Great Wave Planet suddenly multiplied.

It is difficult for the light of the black hole's accretion disk to reach this depth, and the creatures here are very haphazard.

It's almost necessary to have no eyes, and the evolution of the body is adapting to the environment.

A streamlined fish can be seen moving through the water, with muscles that are extremely strong to adapt to the pressure of the water, and their powerful tails make them foam at the water like arrows off the string.

Before they could even react, they lost half of their food, and the other half disappeared into the ocean a few seconds later, leaving only the well-fed predators swimming leisurely.

But this is only one link in the food chain, and the sudden burst of tentacles in the deeper seas has dragged the predator who had just eaten a full meal into the deep sea, and its fate is self-evident.

A complete and stable ecological cycle was formed on this planet, and it was in this area with the largest biomass that Li Wenyuan discovered a "deep-sea observatory" left by human beings.

"What's that?" In the midst of Grey Wind's curious expression, a massive suspended structure standing still in the torrent gradually revealed its full view in the dark sea.

It resembles a giant spinning top, and its outer shell is coated with fluorescent material, making it the only source of light in the dark, deep sea.

The phototaxis of deep-sea fish would have caused the creatures to swarm here, but a sound wave that surrounds the massive structure at all times disperses them.

Compared to the very busy area, it is undoubtedly much more deserted.

But this may be the kind of situation that such a "deep-sea observatory" needs.

As Grey Wind and his drone approached, he also received a signal that the observatory belonged to humans:

["003 Deep Sea Observatory" warm reminder:]

[This is a "fish tank", please don't disturb the ecological environment here, otherwise some poor researcher will lose his research results!] 】

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

“…… This is supposed to be the cultivation area of some kind of experimental material, and I guess the research topic is 'On the evolution of life in the ocean planet in the environment of black holes......"

In fact, it is quite normal for this kind of thing to appear, not to mention human beings, even in today's interstellar society, due to the rapid development of productive forces, there are many experiments carried out on a "planet" basis.

The galaxy is so vast that it can't always be confined to a small planet.

There have been many interstellar tycoons who have bought several barren planets, built artificial eco-cities on them, and captured some natives to treat them as "gods" to enjoy the feeling of worship.

There are also some bold mad scientists, for the sake of some sociological research, quietly invade the indigenous planet, stir up internal turmoil, and then expand the experimental sample.

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

But what Li Wenyuan didn't expect was that in addition to human signals, he also monitored other signals.

This kind of signal is completely different from what humans are commonly used for, but it is full of rules, and it is also a signal sent by an intelligent being.

After the translation, Li Wenyuan became more and more curious about the situation of the "deep-sea observatory".

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