Soon we followed Du Yue to the next level, only to see that in addition to the corpses of humans who had turned into bones, there were also the corpses of some large sea creatures, and the only ones I could recognize were a few huge giant sharks, which almost occupied half of the hall.

Naturally, the smell of the sea is also extremely disgusting, and there is a rotten smell in the salty and salty.

We tried to avoid the shark carcasses as much as possible, and slowly swam against the wall.

Du Yue was obviously familiar with the path here, and shuttled back and forth between the shark and other corpses for a while, and then the angle suddenly changed, and when I turned to the left, I saw a huge door appear in front of me.

This door is still the kind of security door with iris recognition system, but this door is larger than any I've seen before, about three people tall, and the width is twice as wide as a normal security door.

And the structure of this door is also different from other doors, the ordinary security door is a single side open, but this door is closed up and down, there is a horizontal gap in the middle.

Du Yue swept the flashlight beam up and down towards the crack in the door, signaling us to find a way to open the door.

Last time, Du Yue and I encountered the big monster fish that attacked us on this floor, so I couldn't see this door at the time, and it seems that there should be a famous one in this door.

I gestured for all three girls to step back, and I swam backwards for a while, and then a carp swung its tail at the door.

After a dull crash, the door shook slightly, showing no signs of cracking.

My heart sank, and I immediately realized that if I wanted to open this door today, I was afraid that it would take a lot of effort.

After all, it was in the water, and the force of my use of inertia was smaller than that on land, and this door was extremely strong, so it was not easy to break through.

Seeing this, the girls and I also swam side by side, and we began to strike the door several times in succession, but the door still did not move.

I wondered if we couldn't get it out of it with our own brute strength, so did we have to find a big monster fish to entice it to bang on the door, just like we did last time.

However, if you want to find a big monster fish this time, I'm afraid you'll have to find a bigger one.

I motioned for Amy and Xia Ran to stay where they were, and began to swim towards the lower level with Du Yue.

Along the way, all we saw were small and medium-sized marine fish, and I can only hope for luck in the future.

The lower floor used to be a cage area for animals, but now that these iron cages have been destroyed, there are still a lot of traces of underwater firefights here, and the corpses here are all people wearing deep-sea diving suits.

It seems that the previous scramble here is much more exaggerated than I imagined, and I feel that the people of the Salvation Army and the Blue Jays should have invested a lot of manpower and material resources here, and this battle not only involves the land above, but also the fierce fighting under the water.

Du Yue also seemed a little surprised when she saw this, and I saw that she had been checking the corpses nearby.

I'm also starting to worry more about the safety of the finale medicine, these two groups of people are like this, can the medicine still be there?

There is no way to communicate in detail underwater, in fact, I also want to ask Du Yue what is behind the door that closed up and down just now, but judging from the firmness of this door, there must be something important locked behind it, and I hope the finale medicine is inside.

We dived five or six floors in a row, and we still didn't see any large, ferocious sea creatures, let alone attract them......

And I also found that it is not realistic to find animals in this building that can shake the door, because due to the previous fierce underwater battles, many of the equipment in the building have been destroyed, and these destroyed things have occupied a lot of space on the nearby floors, that is, creatures of our size can freely shuttle through it, and large marine animals are probably not bored to run to this place.

Just when I didn't know what to do, I suddenly saw some dark shadows appear at the staircase that led from my feet to the lower floor.

Du Yue also saw it, and she immediately swept towards those black shadows with a flashlight, but these black shadows were fleeting.

Du Yue swept the flashlight beam twice over there, she probably thought I didn't see it.

I immediately nodded at her and raised my nail gun.

I didn't know exactly what the shadow looked like, but I didn't think it was a fish.

Du Yue and I swam left and right towards the staircase below, only to see that most of the collapsed cages had been blocked near this opening, and those black shadows appeared from the cracks in these cages just now.

I tore them all open and swam into the passage below, where there were still a large number of corpses, both animals and people, some suspended in the water, some paralyzed underneath.

More importantly, I noticed that the corpses were not quite the same as the ones I had seen before, there were no steel nails on them, and it felt like they had died in hand-to-hand combat in this cramped space.

At the same time, I also heard a small sound of water flowing at the end of the passage, and listening to the sound, I felt like there were many animals swimming.

I gestured to Du Yue and asked her to cover me behind me with a flashlight, while I held the mountain knife in my right hand and the nail gun in my left hand and slowly swam towards the exit......

It's closer......

The sound of those water waves is also more obvious.

When I was about to reach the exit, a black shadow suddenly burst out, this thing was so fast that even with my current reaction speed I couldn't fully dodge it, but I turned sideways, and the black shadow hit me headlong on the waist, and I was knocked backwards for some distance, hitting the wall.

The shadow was small, about the size of a baby, and extremely nimble, like a small underwater missile, and after hitting me, it reversed its angle and immediately swam back towards the exit.

Du Yue's flashlight beam swept behind me, obviously trying to see what this thing looked like.

But I couldn't even see it, let alone her.

Du Yue quickly swam to my side and asked me if I could see clearly with the shape of my mouth, I shook my head, and Du Yue frowned and made a careful gesture to me.

I regained my body, and I still swam towards the exit with Du Yue in the forward and backward posture just now.

Seeing that I was about to get to the exit again, the black shadows just now appeared again, and this time the number soared to seven or eight, these black shadows suddenly rushed towards me and Du Yue, and then I felt that my hair was being pulled by something, although the strength of this thing was not large, but it couldn't stand the large number, and I felt that my scalp was going to be dragged down for a while.

Even my short hair is like this, Du Yue's situation can be imagined.

I hurriedly looked at Du Yue, and sure enough, I found that her long hair had been completely pulled apart, and her whole person was also out of balance in the water.

I hurriedly shot a few black shadows on Du Yue's head with a nail gun, and several bundles of steel nails hit the target, and two black shadows were hit by this steel nail and retreated, and at the same time, I also recognized this thing!

I grass!

It's those little black things!

It's the kind of black baby we've seen on the island before!

After returning to the land, I had deduced from Niebi and the gecko people who followed him that these swift babies were actually gecko people in essence, but the gecko people were changed from adults, and these little black things were directly changed from the infant state.

When I rescued Li Zhiwen in this underground building, I had already found that these little black things were deliberately arranged in the building to guard some key places, and now we wanted to go down to this floor and were intercepted by them, which means that they must be guarding the things on this floor.

At the same time, I understand why the corpses here were not shot with nail guns, they must have been killed by these underwater black things.

I didn't expect gecko people to be able to survive underwater for a long time, but it doesn't seem strange, after all, gecko people are also closely related to the Gu worm virus, I can breathe underwater, and they can naturally too.

The attack power of these little black things is extremely strong, I soon felt the pain on my face being scratched, I hurriedly pulled Du Yue backwards and retreated, at this time I was swimming backwards completely with brute strength and strong water nature, if it were someone else, I am afraid I would have lost my resistance a long time ago.

Retreating to the top of the stairs in one breath, these little black things finally let go of me and Du Yue, and their bodies swam back to the bottom with a limp.

Damn, it's exactly what I guessed.

When we rescued Li Zhiwen, too, as soon as we approached the security door blocking the road, those black things pounced, and as soon as we got out of the way, they went back again.

It's just that the building wasn't flooded at the time, and we could use our flexibility to resist, and now it's underwater, and I really don't have the confidence to fight them.

Du Yue must have seen the appearance of those things clearly, and I saw that she was waving her hand at me again and again, signaling us to retreat outside the staircase first.

I'm a little angry, I didn't expect to be blocked by these little things, if I knew that, I should have brought Nie Bi with me.

Du Yue and I both hung up more or less in the fight just now, some of Du Yue's hair was torn off, and both of us had different degrees of scratches on our faces, but fortunately, I reacted quickly enough at the time, otherwise our heads would probably be torn apart alive by these little black things.

The two of us rested in the water for a while, and then saw Du Yue find a sharp piece of iron and start carving on a nearby wall.
