Because the sea water is very clear, the situation underneath is almost clear at a glance.

And in the upper reaches of the sea, there are no fish and shrimp at all, and the black shadow set off is even more obvious.

However, the shadow seemed to be at the bottom, so Dai Lin couldn't see the real appearance of the shadow at all, and could only see a long outline vaguely.

She couldn't even tell if the thing was a separate entity, or a school of fish or something.

Under the seabed, marine life often gathers together and is easy to be seen as a whole from a distance.

But even if she couldn't see what the thing looked like at all, Dai Lin still felt a burst of panic. She didn't dare to look any more, and hurriedly pulled Brother Eagle ashore.

The two climbed up from the sea wet and breathless, and then explained to Ouyang Yu and Ji Feng what they had just seen.

When mentioning the shadow, Darling paused and said her thoughts.

"I didn't see any big creatures below, they were all small fish and shrimp, so I suspect that the shadow may be formed by many small fish gathered together."

"I think that thing is like a creature, a living thing." Brother Eagle who was acting with her naturally saw the thing, and Brother Eagle had the opposite idea.

They are not so afraid of the former, but if it is the latter...

"Have you seen any buildings like doors below?" Ouyang Yu asked.

Speaking of this, Dai Lin shook her head in frustration.

Before she had time to continue diving, she was stimulated by an inexplicable sense of crisis and ran up.

Just now, except for some smaller marine animals, I didn't see anything else, not even coral.

In this way, the sea is really strange.

On the surface, everything looks normal, but after going down, I find that there are no animals and plants that should be found in ordinary seas.

I just don't know which part is the problem.

Is it because the material of this seawater is special and not suitable for the survival of ordinary animals and plants, or is it…

"Something is restricting the survival of other animals and plants." Ji Feng said.

Dai Lin instantly thought of that dark shadow again.

Although she didn't see clearly, her sixth sense was not false.

The experience accumulated over the years of fighting has given her an ability to predict in advance. Many times when she encounters danger, her body is the first to detect and prompt her.

Many people who fight often have this ability, and Brother Eagle and Ji Feng are no exception.

Therefore, both of them did not take Dai Lin's feelings seriously, but they were more cautious about the sea.

But no matter how cautious they are, as long as they want to leave here, they will inevitably go to sea again.

Just now, Dai Lin and Brother Eagle have already gone down, so this time they decided to let Ji Feng and Ouyang Yu go down to see if they can find anything new.

Although Ji Feng's body is not completely healthy, there is still no big problem in the next water.

He and Ouyang Yu didn't dawdle, and went straight into the sea.

Because Dai Lin and Brother Eagle have already explored the upper reaches, the two of them didn't waste time on it this time, and went directly to the depths.

Soon they swam to the deepest position that the two of them dived to. Sure enough, as Dai Lin said, the surroundings gradually changed from nothing to some small fish and shrimp.

And Ji Feng has a new discovery, which Dai Lin and Brother Eagle haven't mentioned before.

Generally speaking, there are many species of animals and plants in the sea, and the ecosystem is stable but very chaotic.

This also leads to the fact that the animals on the seabed generally do not respond much to other creatures that suddenly appear around them.

As long as their lives are not threatened, i.e. disturbed, they can live in peace with other creatures.

But now, as soon as Ji Feng and Ouyang Yu appeared, the fish and shrimps that were swimming slowly around them suddenly all swam away like frightened birds.

As if a vacuum was formed around them, the few living creatures dared not approach them at all.

Not only that, Ji Feng also did an experiment. He deliberately swam to places with fish and shrimp, but as long as he tried to get close, those animals would swim farther away from him in an instant, as if Ji Feng was some kind of beast.

The animals are too scared of them too.

One or two is nothing, it's not normal for all animals to be like this.

The two made a gesture and continued downstream together.

They wanted to see what the bottom of the sea looked like.

After a few meters further downstream, the two finally swam to the bottom.

There are a few places on the bottom where some corals and the like grow, but they are also very small, as if they have just grown.

There are also some shellfish and other marine life, but without exception, all animals and plants seem to be in their infancy.

Of course, it is also possible that the characteristic of this sea area is that everything does not grow here.

Without much time to study the biosphere here, they groped around on the bottom of the sea, trying to find the so-called "door".

But the bottom of the sea is empty, and there is no so-called door at all.

After some groping, the mysterious voice appeared again.

What Dai Lin described to them just now was very unclear. She said that she couldn't find the right words to describe the voice, but she just said that she had never heard it before.

Ji Feng couldn't imagine it at first, but now, listening to the bursts of cries coming from his ears, he understood why Dai Lin said that.

At first glance, this sound sounds like a mixture of many different sounds. The screams of people, the roars and chirps of various animals, gathered together to form a very strange but very intimidating sound.

But if you listen carefully, it doesn't feel like this. It's the same creature. It's like a howl, and it's like some kind of snoring. Anyway, it's complicated.

But it is undeniable that Dai Lin's feeling is right.

The moment they heard this voice, the hairs on Ji Feng and Ouyang Yu exploded.

Ouyang Yu immediately turned to look at Ji Feng, her eyes were full of panic, as if asking Ji Feng what to do.

Ji Feng looked around and found that since the sound appeared, all the living things around them had disappeared.

It's not the kind of "disappearance" that was far away from them before, but just disappeared, maybe all of them were suddenly hidden.

Obviously, it's not just humans, these things are more afraid of that weird voice.

In the distance, an indistinct huge black shadow began to appear, and the shadow grew bigger and bigger, almost covering their sight.

This also means that the thing is approaching them.

Go, or stay and see what that thing really looks like?
