Under certain conditions, bones can exist for millions of years and become fossils. However, that condition is extremely harsh. However, the abandoned prison in this desolate underwater city obviously does not meet such extreme conditions.

The sea creatures here are different from ordinary sea creatures. Ordinary bones can't bear the bite of these sea creatures. It may be only a few years, and the bone will be incomplete. But the bones are so well preserved? Han Fei was shocked.

After crossing the rotten threshold, Han Fei ran to it and pinched it for a few times. He found that the bone was still very hard. He didn't know whether it was a long time of cultivation or something

With doubts, Han Fei went on to the back cell. On the wall along the way, because the age is too long, it seems to be moldy everywhere, crawling with all kinds of strange mosses. Some mosses attach directly to the bones.

Over hundreds of cells, Han Fei found that not every cell has a skeleton. Perhaps, it is also related to the strength of these prisoners' practice. When the city was in disaster, no one should let them out, resulting in many people trapped in their cells.

After several turns, Han Fei didn't find anything special, not even a marine animal.

"Eh, six masters, do you think there will be a place on the sea floor where there are no marine animals?"

Han Fei is very confused. He should not. Even if it's safe here, you're under the sea! You don't have any small fish or shrimp. Do you have some hermit crabs or crabs that are born secretly?

Six starfish's eyes turned: "I feel a little dangerous here."

"Danger?"

Han Fei frowned, not knowing what the danger was in this place. Up to now, he hasn't seen a moving creature. What's the danger?

Suddenly, at a turn, Han Fei stopped.

There is no way. But after the corner, there was a way to go down.

Han Fei held up the flashing light, lit it, and then walked down the steps.

"Hula..."

When Han Fei was about to go to the next prison, he suddenly saw a pair of eyes flickering. Then, a shadow flashed by.

"Who?"

Because it's too fast, Han Fei just catches a glimpse. The height of that man seems to be much shorter than himself. Then, the man ran out in a strange position, like half running and half swimming.

Han Fei called out the fishing rod and waved the hook. But after two turns in a row, the thing disappeared.

"Eh! Is there anyone else? "

"I feel a little familiar," said six starfish

"Are you familiar with it?"

Han Fei said speechless, "is it difficult? Can you know it? You've been in a normal fishing ground for 300 years. Even if you came here as a child, who can stay here for 300 years? "

Six starfish's big eyes purr: "I don't know, but I feel a familiar atmosphere."

Han Fei took back his fishing rod and added dozens of blue sea dragon blades to his side. Since there are creatures here, are there any secrets?

Han Fei didn't go after it impulsively. Now, this layer of prison that comes into my eyes is better preserved than the one above.

Han Fei walked along the road to a cell. The door had been destroyed, and there was a skull in it.

Han Fei only felt that all his gooseflesh had risen. If you want to stay, just leave a whole body! But you've left a skull. What do you mean? What about your body?

Han Fei felt more and more uneasy. From the moment he came in, he felt something was wrong.

Han Fei turned his head abruptly and saw nothing. Within the scope of spiritual perception, it is also empty.

Walking along the cell, Han Fei found that many cells were empty. If there's space, there's either a skull in the cell. Anyway, there is no other part of the body.

Han Fei pulled his tongue: it's hard. What kind of monster is there? Or does the city have the custom of killing prisoners and throwing their heads in cells?

All the way forward, Han Fei still found nothing. Instead, he found another step down.

"How many floors are there in this prison?"

Han Fei suddenly shivered: don't tell me, there are 18 layers of Aung here! You can see the oil pan or something down. Then I will turn around now

This time, Han Fei saw a pair of eyes staring at himself in the dark corner. Han Fei was horrified, but his eyes just looked at himself, and then he ran again.

This time, Han Fei stepped out and quickly appeared in the third prison.

As a result, as soon as he entered the lower prison, there was a smell of wind.

It's too late. At that time, dozens of blue sea dragon blades were split at the same time. Han Fei controls the blue sea dragon blade and almost cuts it in the dark.However, only the sound of "Ding Ding" was heard. On the ground, a strange figure is swinging its tail. The blue sea dragon blades are thrown out one after another.

"Lizards? Giant salamander? The dragon snake

Needless to guess, Han Fei saw a man's head on the ground. Then, Han Fei really wants to run away. That thing is too ugly!

To describe it in detail, it's a human head with only two holes in the nose and sharp teeth in the mouth. It has two skinny hands.

The movement of this thing depends on these two hands. Except for the webbed hands, the hands of this thing are almost the same as those of thin adults.

Further down, it is what really shocked Han Fei. Because the body of that thing, like a fish, is still dragging a long tail.

At the moment, the tail of the thing arched, revealing a bone spur on the tail.

In Han Fei's eyes, the data are as follows:

[name] immortal Mermaid

[introduction] the lowest level of living creatures in marine primates, evolved from ordinary Mermaid in special environment, has extraordinary vision. Their teeth are extremely sharp, and they can bite through the medium spirit tools.

[grade] 37

[quality] variation

[contains Reiki] 3358 points

[edible effect] inedible

[collectable] none

[non absorbable]

Han Fei was confused at that time: do you call this thing a mermaid? From what common mermaid? After so long evolution, such a thing came out. How ugly was it before it evolved?

Seeing the immortal Mermaid, he suddenly jumped up, with sharp claws on his hands. At the same time, his mouth was so wide open that he showed his sharp teeth. He seemed to want to eat Han Fei alive.

"Bang!"

I saw a small seal take the past, Han Fei used 80% of the power to take this thing. For nothing else, it's really ugly. I think if this thing pours on me, it's disgusting! Simply, Han Fei didn't need to drink blood knife either. He took the watermark directly.

The immortal Mermaid rolled many times on the ground and finally hit a cell directly. Han Fei immediately rushed over and prepared to shoot again.

As a result, the next moment, a human skeleton is lost by that thing. Han Fei subconsciously took a picture of the past and shot the bone in pieces.

But the most noticeable thing for Han Fei is that the skeleton has a tail. However, this body is relatively complete. From the head to the pelvis.

But below the pelvic cavity, there are bones one by one.

"I'm a good girl, isn't this the real mermaid?"

Han Fei swallowed his saliva: in the past, people used to make false claims that there were mermaids in the sea.

Han Fei has been wandering in the sea for so many years, and he has never seen such a creature as a mermaid. Otherwise, he will definitely go home and become his first wife.

But now, he felt that his cognition had to be changed. Maybe mermaid is a real creature, but it's not as beautiful as you think.

At the moment, the immortal mermaid was in the corner, looking at Han Fei in horror. From time to time, he yelled at Han Fei, the buckteeth in his mouth, which made Han Fei spit out his stomach acid.

This immortal mermaid was paralyzed by Han Fei's photos. The lower half of his body seems to be unable to move. At the moment, I can only use two hands to pick and pull at random and shout at Han Fei.

Han Fei took a look at it disgustingly, and then hit it dozens of times with the watermark "bang bang", directly beating it to death.

"I'll keep you alive. Is it true that you're so named? blamed. What the hell is this? Why is there such a thing as a mermaid? "

"Hiss..."

Six starfish: "be careful."

Han Fei turns back, drinks the blood knife to wield, another immortal mermaid is cut into two sections by Han Fei.

Han Fei's face is ugly: "this is not all this stuff, is it?"

Han Fei doesn't think there will be any treasure here now. Sure enough, not all the secret places are organic

When Han Fei walked out of the cell, he found that at the end of the passage, several secluded eyes were staring at him. However, this time, these things did not rush up, but gradually retreated.

Han Fei hesitated for a moment, looked at the circuit, and finally chose to move on. It's just that he's so curious. The mermaid is not like Yang Ruoyun who has completely become a fish. This is the real mermaid! What will happen at the end of this prison?

Six starfish grabbed Han Fei's shoulder: "still going?"

Han Fei: "I'll take a look and go out."
