The fortress descended quickly, and as it continued to penetrate into the sea, the light around it became dimmer and dimmer, except for the life shield of the fortress that emitted a faint yellow glow, illuminating a small area around it.

Miraculously, the deep sea is not completely dark, and there is always a faint ambient light throughout the sea.

The biodiversity of the sea is far greater than that of the land, and in this great wave of global life evolution, marine life has also undergone earth-shaking changes.

Before the end of the world, no one knew how many species of life there were in the ocean, and now it is even more impossible to count. Schools of fish that Leon had never seen before swam past the fort, and Leon couldn't even be sure if they had evolved or not.

The fish that were originally wandering leisurely suddenly scattered in panic, and it turned out to be a huge shark rushing into the fish, and its sharp teeth were scattered and flying, easily penetrating one small fish after another, while the big shark itself swam leisurely and devoured the small fish that were killed.

Just when the big shark had just finished eating a small school of fish and was satisfied, a huge octopus tentacle stretched out from the darkness in the distance, firmly entangled the big shark, and the big shark lost consciousness and was dragged into the darkness without a few struggles.

The world of the deep sea, primitive and bloody and wonderful.

This sea area is not very deep, and the bottom of the sea can be vaguely seen after diving for about 500 meters under the fortress.

Li Ang has seen the colorful underwater sea on TV more than once, but it is the first time to dive into the bottom of the sea and witness the magnificent and strange scenery of the seabed, and he can't help but sigh.

Colorful corals, giant kelp swaying with the waves, seaweed, and giant jellyfish swimming leisurely with a strange brilliance, everything is so beautiful.

"The fish is over there." Sora stretched out his claws and pointed to a deep black ravine.

The trench is so long that you can't see the end of it on either side, and it winds and turns, giving it an eerie feel.

Li Ang looked at the trench and was very worried, this trench is only about 50 meters wide, although it is wide and narrow, but the widest place is only seventy or eighty meters, which is not at all a huge fortress can go down.

"Can you shrink the fortress?" Li Ang just asked casually, and he didn't report hope at all.

Did the fortress fail to work miracles, getting bigger and smaller? Is it really a youkai?

Fortunately, Xiao Huang also has the ability of the water system, although it is only level three, there is no problem with bringing a Li Ang. Receiving the empty space as a summoning space, Li Ang was slowly led by Xiao Huang into the cold trench.

The sides of the trench were full of rugged rocks, interlaced with canine teeth, hideous and terrifying, without the slightest plant, nor the slightest sound or light, like a dead field.

I don't know how deep this trench is, and in the perception shared by the air, the target fish is still deeper in the trench.

Silent, pitch black, cold, monotonous, Leon couldn't tell how long it had been in this trench, and he couldn't figure out the front and back, left and right, southeast and northwest, so he could only follow the induction machine.

Go down a hundred meters, almost reach the limit of Xiao Huang, the trench here is already very narrow, the widest place is only four or five meters, the bottom of the trench is faintly visible, looking in the direction of induction, a cave emitting a faint blue-green fluorescence is impressive.

Leon didn't encounter any creatures along the way, but at the mouth of the cave, there were six strange fish swimming back and forth, as if they were patrolling.

The strange fish is extremely ugly, with an excessively large head, which occupies almost two-thirds of its body, and rows of sharp and messy sharp teeth can be seen from the slightly open mouth.

This strange fish is somewhat similar to the piranha that Li Ang has seen, but it is larger, slightly smaller than a dolphin, and its head is larger and more hideous, and its attack power must be extremely strong.

The goal of this trip is mostly in this hole, and it is obviously impossible to enter without alerting the fish guards at the door, and Li Ang is too lazy to use his brain to think of a way, he just wants to complete the task quickly and leave this oppressive and uncomfortable trench.

As a guard at the door, it is naturally not too strong, and there is no need for Li Ang to do anything with the strength of the two levels.

But what Li Ang and Xiao Huang didn't know was that before the strange fish died, it sent an imperceptible infrasound wave to the depths of the cave, transmitting a dangerous signal.

There was a spherical cave in the deepest part of the cave, and the purpose of Leon's trip was in this cave, and it was the same strange fish as the guard outside, but it was larger, the size of a killer whale.

The giant monster fish received the warning signal from the guard at the gate, and swam out angrily, it is the absolute overlord of this sea area, who dares to kill its people?!

As the giant fish swam out, more and more came out of the fork in the cave behind it to follow their king.

After Li Ang eliminated the fish guards at the entrance of the cave, he cautiously came to the cave, only to see that the rock walls around the wide cave were inlaid with blue or green luster jade, exuding a faint fluorescence, this is not the legendary pearl of the night, right?

When Li Ang just thought about going to detain one and come down to see what was going on, he only felt a huge and terrifying aura coming from the depths of the cave, and he didn't think much about it, so he directly asked Xiao Huang to quickly run away with him.

Facts have proved that Li Ang's decision is very correct, not long after Xiao Huang took Li Ang out of the cave, the strange fish quickly chased out, following the residual breath of Li Ang and Xiao Huang.

Although the trench was dark, Leon could barely see a hundred meters with his eyesight. Looking back at Li Ang, who was suddenly frightened, his scalp was numb, and countless strange fish swept in like a dark cloud.

Xiao Huang took the oil bottle of Li Ang and used his milk to drive the water to swim out of the trench at great speed. After all, Xiao Huang's water system ability is only level three, and he is not a pure aquatic creature, and the distance between him and the strange fish school is constantly narrowed.

Li Ang, who has experienced a lot of big scenes, also cleaned up his mood at this time, and looked back at the strange fish carefully, the particularly large head led by him was the purpose of his trip, and he was originally worried about how to find it and how to take it out, but now it is convenient, just don't be caught up.

A faint bright silk line above quickly enlarged, the exit of the trench was imminent, and the strange fish group behind him had already leaned over, the strange fish king was still dozens of meters away, and its little brothers had already opened their mouths to bite Li Ang and Xiao Huang.

Li Ang's long knife slashed, cutting all the strange fish that rushed up in half, and the light blue blood drifted away, making the other strange fish even more violent, and the speed of swimming increased a few points, and the strange fish king let out an angry roar, which was extremely ugly.

Li Ang's long knife dance was surrounded by afterimages, constantly killing the strange fish that rushed over, and he didn't have time to be surprised that a fish would roar.

Finally, Xiao Huang rushed out of the trench with Leon, and the fortress had been waiting for a long time. In the face of the huge and powerful fortress, the strange fish did not have the slightest fear, and rushed to the fortress with the stubborn and unyielding spirit of biting off a piece of meat even if they died.
