The fat man was the first to get into the water, and he was much better at water than the rest of us.

The dim water of the pond was like a black lake, and the fat man did not make any movement for a long time after he got into the water.

I couldn't help but start to worry a little about whether this kid would have encountered any accidents down there, but with his physique, even if he encountered something, he wouldn't even be able to splash water.

Unexpectedly, just when everyone was a little worried about him, the fat man suddenly came out of the water, and then gasped for breath.

His blushing face looked like he had just struggled through the ghost gate.

"Damn, isn't this map fake..."

The fat man scolded angrily and was indignant, apparently having just encountered danger in the water.

I suppressed my curiosity, let him catch his breath and pull him ashore, then asked him what was going on underwater.

"The water is muddy, there are many dead people's bones, and most importantly, a wall that seals the road."

After the fat man finished speaking, he wiped the black water on his face with his hands, and a foul smell permeated his whole body.

"How is that possible?"

I couldn't help but stare at the map in my hand, thinking that since they had an alternate route marked on the map, someone must have inquired about it in advance.

Besides, how can there be a wall in the water?

"Not only that, but there are also mantras carved on the walls like Fan Wen, which seem to suppress something."

This time the fat man's words instantly caused panic in the team, and even I felt a little uncomfortable, and my scalp was numb.

But there is no way out now, even if there is a hidden Yama Lord in the pool, he has to be brave enough to break through.

This time I decided to go into the water with the fat man, and everyone took out all the remaining ropes and put them together to form two safety ropes.

Tied to me and the fat man, respectively.

Before entering the water, I gave a solemn look at the little white face and the dragon boy, and if there was any danger, I would try to make a splash in the water.

The dragon boy with the safety rope in his hand will also desperately drag the two of us out of the black water.

Until the whole body was completely soaked in black water, a feeling that had never been felt before burst into the whole body, and the large and small wounds on the body were itchy and unbearable under the black water.

The most lethal thing is that the visibility under the water is really low, and the depth of the pool is at least two or three meters.

At the bottom of the pool were strange veterans in black straitjackets with bolt-action rifles, most of them soaked to the bone.

There was nothing in the empty eye sockets, all staring at me and the fat man.

The pressure under the water was getting stronger and stronger, and I even felt a little out of breath, and finally when I was about to lose my breath.

I finally saw the wall that the fat man had spoken of under the murky water.

The wall is covered in black silt, and when you touch it with your hand, you can clearly feel that the wall seems to be carved with strange patterns.

In the very center of this wall, there is a stone carved disc, which corresponds to the four directions of up, down, left and right under the water.

Underneath each direction were rusty chains, sinking straight into the cracks in the walls.

Until then, I couldn't hold back my suffocating head anymore, and I only felt a few large mouthfuls of black water pour into my throat and nose.

The safety rope around my waist suddenly exerted force, and I was quickly dragged out of the pool, followed by the fat man.

The black water that ran down my throat and into my stomach choked on nausea, and I couldn't help but want to take off the mask on my face and bend over to vomit.

only to find that the barbs on the mask were all deeply embedded in the flesh, and if you took them off hard, you would have to break them.

The fat man told everyone about the underwater situation, and I added a few more words.

The circular stone plate on the underwater wall seems to be some kind of strange and mysterious combination lock, and the four directions corresponding to the chain lock are the key to opening the stone wall.

But unfortunately my water quality is too poor, and when I just got into the water to reach the wall, I ran out of air.

At the moment, how to solve the problem of insufficient oxygen seems to be the most important thing.

The only person with the best water quality here is the fat man, followed by me, although he can hold his breath in the water for a long time, but if he encounters any danger, he can't parry.

Someone had to dive into the water with him.

I recalled the strange patterns and stone plates on the wall under the pool, and simply sketched lines on the ground with my fingers for Uncle Nine to see.

I saw him squinting his eyes and looking at it for a long time, but he didn't see the mystery, maybe the underwater light was too poor, and I could only draw the scene of the mechanism little by little with my own memory.

There may be deviations between the picture on the ground and the real situation, but Uncle Nine also said that he has never seen such a strange pattern.

and the stone disc chain mechanism on the wall.

I looked at the old map in my hand, and it suddenly occurred to me that the mysterious unit with the number in disguise had left behind the diving equipment.

This small island is surrounded by the sea on all sides, and since they have come prepared, they must have prepared simple diving equipment.

I turned around and walked back into the corridor with my torch in hand, only to see a dusty wetsuit next to the simple command table.

This seems to be the oldest-fashioned one, but it was only available from abroad a few decades ago.

Now that the outfit still barely fits, the fat man and I packed up our gear, and now that we have diving equipment, I'm not afraid that I'll stay in the water for too long.

You can also patiently crack the mechanism of the stone plate chain underwater.

The fat man told the dragon boy a few times, if there is any danger or any accident on the shore, pull the safety rope first and drag the two of us out.

The second time I dived into the water, I had some experience and memories, and I followed the fat man and dived desperately to find the location of the stone wall.

The oxygen in the oxygen tank has not leaked and been exhausted after decades of consumption, but the air stored in it has long since deteriorated.

When I breathe into my mouth, I have an indescribable smell, but I have to endure it in order to survive. Even if the oxygen in it is toxic.

It was muddy in the dim light, and this time I seemed to faintly see a black shadow swimming in the muddy waters.

I don't know if I was hallucinating underwater, or if there was really a black creature parasitic underwater, and I felt a little dizzy after diving two or three meters in the blink of an eye.

And the dark shadows swimming back and forth overhead gradually disappeared, which made me breathe a sigh of relief.

The fat man looked at the chain stone plate in front of him, and although he couldn't speak, he kept gesturing to me.

I knew that the stone plate in front of me must have been composed of some sort of orderly mechanism, and the four chains and directions extending from the crack in the stone must be the key to cracking the mechanism.

But even though the light was much stronger, I still couldn't see the strange symbols carved on the stone plates, let alone be able to solve the mysteries of the mechanism.

Time is pressing, and I can't take care of many dead horses as live horse doctors.

He grabbed the bottom chain with his hand and pulled it hard.

I heard the sound of a mechanism rubbing gears from under the water, "Click." ”

Immediately after that, there was no movement, and I wondered why the stone wall in front of me was still unresponsive.

Could it be that he pulled the wrong mechanism just now, thinking that his hands involuntarily stroked the mysterious pattern on the stone plate again.
