A trench at the bottom of the sea, which looks similar to a valley on land.

The surrounding rocks, jagged.

It's just that.

These rocks do not grow moss, but are covered with a layer of marine microorganisms.

This trench is not a trench.

When swimming from Zhang Yi's direction, the width of the two sides was almost as wide as a few hundred meters.

Some relatively narrow places are only a few tens of meters.

But.

The depth is much greater than that of the seabed elsewhere.

Say it's a trench.

In fact, it looks more like a large rift valley at the bottom of the sea, which is probably caused by the movement of the earth's crust.

Zhang Yi along the edge of this trench.

Keep swimming forward.

The diving suit has electronic equipment that can record his latitude and longitude position, and as Zhang Yi's position changes, he is also quickly approaching the coordinates of the wreck of the Coburnie company.

Afterwards.

About ten more minutes passed.

Zhang Yi had already reached the coordinates given by the pigtailed man.

On a boulder near the edge of the trench in front of him, Zhang Yi stabilized his body and irradiated the depths of the trench with the penetrating SR-315.

The relative depth of the trench is also nearly a kilometer.

The headlamp, which has a penetrating power of only 100 meters, shines towards the bottom, as if it shines into an invincible abyss, and nothing can be seen except for some fish and other sea creatures swimming around.

And.

There are no traces of shipwrecks in the vicinity.

Want to find the shipwreck.

Zhang Yi could only continue to dive.

Adjust the light of the headlamp to the normal irradiation range, and Zhang Yi continued to go down.

But.

Zhang Yi also saw it on the description of the diving suit.

This heavy diving suit cannot dive more than 5,000 meters, which is 4,000 meters deeper than the average depth of the Pacific Ocean. Therefore, when Zhang Yi continued to dive, about two minutes, it was estimated that he had dived another twenty or thirty meters.

The wetsuit wrist indicator light is red.

This is a danger warning!

But.

Zhang Yi didn't stop.

In his opinion, Cheng Hu is likely to be trapped in the shipwreck. If there was an escape pod in the big ship and Cheng Hu was trapped inside, then Zhang Yi rushed over and it was still possible to save him.

Even a glimmer of hope, Zhang Yi can't let it go!

So.

Zhang Yi turned off the hazard warning lights.

Continue to dive.

In fact.

When he was close to the trench, his body already felt the pressure brought by the seawater.

He dived around the fish in the vicinity.

Suddenly, his flashlight swept a hideous face. It was not small, and it even looked like the head of a giant python in the rainforest.

The light even swept across his blade-sharp teeth.

Really.

The danger in the trench doesn't just come from the sea.

See here.

Zhang Yi immediately turned off the long-distance lighting equipment and swam in the other direction. He sped up, but not as fast as the thing.

In the process of swimming forward.

Zhang Yi also pulled out a dagger.

If he was on land, even if he encountered any beasts, Zhang Yi would have the confidence to fight them. But in the sea, it's too hard to fight a giant monster fish.

It's not on land.

The sea resistance is very high, and he is wearing a heavy diving suit, Zhang Yi's movement will be very slow.

Therefore, he took out the dagger, which can only be regarded as a subconscious behavior.

Whew.

The sea is churning.

The huge black shadow, opening a huge mouth full of blade-like teeth, quickly bit at Zhang Yi.

At the bottom of the sea.

The speed of this fish is lightning fast.

And Zhang Yi used the reaction force of the flippers to turn over in the water.

It's not that easy.

But he still barely managed to dodge the attack of this strange fish.

At close range, Zhang Yi could already see that this should be the kind of frilled shark that Zhang Yi had heard of before. It is about two meters long, and its head resembles the head of a giant python and the head of a dinosaur.

A pair of huge eyes, as if staring at people angrily.

It looks very hideous.

The frilled shark pounced and missed.

Zhang Yi took advantage of this opportunity to quickly swim towards a lighted place in front of him. Of course, that's not really a light, it's some fish that glows.

Zhang Yi swam over there to disrupt the frilled shark's line of sight.

After all.

Other fish can also be used as food.

Perhaps, when it is full, it will not chase Zhang Yi anymore.

Moment.

Zhang Yi thought so in his mind.

But who knows, after rushing over.

The fish, as if frightened, scattered in a hurry. And the target of the frilled shark still did not change, and it bit at Zhang Yi again.

Zhang Yi quickly avoided it.

There is no road ahead, it is the edge of the trench.

The speed of swimming upward was bound to slow down, so Zhang Yi had to quickly turn around and go downstream along the trench.

Several attacks by the frilled shark were dangerous.

Zhang Yi avoided it.

But.

Every time I did my best.

I can't be sure if he will be able to avoid it next time.

Soon.

Zhang Yi saw an irregular cave in front of him.

It appears to be a naturally formed stone cave in the rock.

originally wanted to get in, but Zhang Yi thought about it carefully, the size of the frilled shark was about the same size as a human, and if he really got in, it would be a dead end.

There may be nowhere to hide.

I thought about it for a moment.

Zhang Yi took out a deep-sea cold firework from his waist.

After polishing it, he threw it into the cave next to it.

At the same time as throwing it out.

Zhang Yi extinguished all the lighting equipment on his diving suit to hide his figure.

I don't know if this frilled shark senses where it is through light, and this can only be regarded as a try, and the dead horse is just a live horse doctor.

But.

Unexpectedly, the frilled shark really chased the cold fireworks.

Plunged headlong into the cave.

The cave is about the size of a person.

The frilled shark goes in, can't turn its body, and it takes a lot of effort to get out after entering.

This bought Zhang Yi time.

He quickly evacuated.

About a dozen meters away.

There was a violent churn below, and cold fireworks were poured out of the cave over there. Moreover, Zhang Yi glanced back, and he also found that in that cave, a huge sea snake actually rushed out.

Zhang Yi has never seen anything like that at all!

But.

His first impression was that it was a giant sea serpent!

It looks like a legendary water monster.

And.

The body of this sea snake will also emit green phosphorescence, which is estimated to be the same as the luminescence principle of other luminescent fish, relying on the luminescent cells in the body to emit light.

The cold fireworks seem to anger the sea serpent.

And it just so happened that the frilled shark rushed in.

So.

The giant, sea serpent-like creature gets tangled in a struggle with the frilled shark.
