The cave is deep and cold, but it is full of the sound of water, as if there is a stream of water in the depths of the cave.

Wan Lin's ears could vaguely hear the sound of dripping water.

The surrounding stone walls were damp, and he could see the condensation of water on the stone walls by the light.

In addition to the sound of the water flowing in the cave, it was the sound of his footsteps, stepping on the stone and making a "stamping" sound.

Wan Lin took a deep breath of oxygen, he was ready, he had even defeated the spicy giant scorpion, and he would definitely not be able to deal with the mutated creatures that might appear in the future.

But when he thought of the overlord shark in the sea, he couldn't help but swallow his saliva, the mutant shark shouldn't appear here, right?

He didn't feel this way in Bermuda before, but here, all the cells in his body shouted: Attention, attention, something is coming!

I don't know how long he walked, Wan Lin only felt that the cave was getting deeper and deeper, he seemed to have walked thousands of meters, why hadn't he reached the end yet.

"Click!"

His foot stepped on something, as if it had been crushed.

Wan Lin lowered his head and looked, it didn't matter if he didn't look at it, he was about to scare his little soul away.

He stepped on a broken metacarpal bone under his feet.

Wan Lin instantly retracted that foot, squatted down and looked at it carefully.

It was a relatively small metacarpal bone, which looked the size of a child's palm, but it had five distinct fingers, and it was a human metacarpal bone.

This discovery made Wan Lin feel cold on the back of his neck, and when he came to find the upgraded items of the water source grass, he could even find human bones.

This is an inconspicuous island among thousands of small islands in the Pacific Ocean, which can make him encounter the scene of a murder, and he doesn't know who the murderer is!

Piranha, perhaps? Shark?

But why are human bones here?

Wan Lin was vigilant, could it be that the water below was connected to the sea? And then the sea will rise here, and then the murderers will come in and eat people?

Or is it the water from somewhere else that brings the bones here?

Wan Lin's head began to think quickly, but he couldn't think of a reason.

Every possibility is open to proven.

He stood up and walked towards the cave again.

Further on, the road began to flatten out, no longer extending downward, and as he walked, a little blue fluorescence appeared in front of him.

Wan Lin slowed down, slowly approached, and found that it was some blue stones on the wall.

His mood instantly became excited, were these stones an upgrade item for the Water Source Grass?

Wan Lin raised the laser sword in his hand and was about to slash towards the stone wall.

At this time, a "snap" footsteps suddenly sounded.

Wan Lin's body shook, stopped his movements, and looked sideways.

There was no longer a cave ahead, but a spacious belly.

Cave belly again?

He remembered the lava crystal from before, which was found in the belly of the cave.

The footsteps of "pop papa" were getting closer and closer, and Wan Lin didn't have the heart to dig the blue stone anymore, but turned to look at the mouth of the cave.

That's where that voice came from.

A short figure suddenly appeared at the mouth of the cave, and suddenly burst out into a sharp shout, piercing Wan Lin's eardrums swelling.

"Ding! Activate the auto-defense mode for 180 minutes! ”

The defensive brooch on Wan Lin's chest was directly activated, his head was slightly dizzy, he shook his head and stood still, the laser sword in his hand was held tighter, pointing straight at the short figure.

The short figure walked very strangely, and there was not just something behind him, and there was a sound of "popping" all the time.

When the figure approached, it really startled Wan Lin.

I saw a dwarf with a sharp tooth body appear in front of him!

No, it's not a dwarf, it's a mermaid!

Wan Lin saw the fishtail behind it!

However, he looked at the mermaid's chapped skin, wrinkled face and body.

What the hell is this mermaid? Not an old mermaid?

The mermaid watched as Wan Lin did not faint after its scream, her eyes were full of consternation, and the eyes that were occupied by red pupils immediately became fierce again.

It opened its mouth, a pair of teeth were extremely sharp, and grinned at Wan Lin for a while, and the fishtail behind it slapped it to the ground, and its whole body bowed, and it rushed towards Wan Lin.

Wan Lin held the laser sword and slashed straight in the direction that the mermaid was rushing from, and was stunned to split the mermaid in half.

A smell of blood then spread, and the mermaid's body, which had been split in half, was dry, and only a large amount of blood flowed out after a human heart was cut, and the smell of blood spread from here.

The heart was like storing the blood of the whole body, and all other facets were burned to charcoal.

Wan Lin watched as his heart slowly stopped beating and turned into a thin film of blood, and he couldn't help but shudder.

He looked at the mermaid's corpse that had fallen to the ground and was still twitching slightly, and his body couldn't help but take a few steps back, but his eyes couldn't help but look at its hand.

It was a pair of tiny hands, which looked like the hands of a child, but like a human.

He couldn't help but think of the palm bone he stepped on earlier, wasn't it a human corpse, but a mermaid's?

Wan Lin smelled the smell of blood in front of him, but secretly said in his heart that it was not good, this would attract more mutated creatures, and he glanced at the blue stone on the wall with nostalgia.

Since it's on the wall, there's probably something inside.

Wan Lin was actually curious about the appearance in the belly of the cave, and was ready to find out.

There's a mermaid here!

Although he didn't know if this mermaid was a product of mutation, it couldn't stop him from moving forward.

Wan Lin walked around the corpse and walked into the cave, where he saw a scene that surprised him.

I saw that the cave was not particularly large, it was a shallow puddle, but the puddle was full of white bones.

There are fish tails, there are human bodies, and there are skulls.

Directly in front of the puddle shimmered dense blue dots, and the blue light shone on these bones, with a hint of horror.

Wan Lin swallowed his saliva and slowly walked a few steps closer, he pricked up his ears and listened to the movements around him.

There was no sound other than some water sounds.

Wan Lin turned around in the belly of the cave, and found no other creatures, thinking that the bones in these puddles were all leftovers from the mutated mermaid, and it was also because of eating the "grain" that the body would become so old, right?

Wan Lin guessed.

He turned his head to look at the blue spots of light directly in front of him, the blue stones embedded in the walls.

If he's not mistaken, there's only one upgrade item that could be the Water Source Grass.

Wan Lin raised the laser sword in his hand and slashed at the stone wall.
