Originally, I thought it was a naturally formed cave, similar to a karst cave, but now I look at it and look at it differently.

Beside me, instead of the stone walls and stalactites you usually see in caves, there was a half-collapsed brick wall with many huge cracks in the wall.

Some have collapsed, some are still struggling to support themselves, stretching into the distance, and the so-called reef under my feet is not a reef, but a few huge beams.

It was covered with a lot of mud ash and brick walls before the water surface was exposed. There are also some old-fashioned tin carts, rotten wood, and discarded washbasins floating on the waterhole nearby, which is clearly an abandoned mine that has been submerged by the sea.

I was a little surprised, but also a little puzzled, originally thought that this was a cave under the reef, and if you fell down, there must be no return, but now this is a ruined mine.

The mine must not have been dug directly from the bottom of the sea, it must have some passage to the top, or to the shore, or to an island, and as long as you follow the passage, you can basically walk up.

It didn't take long for the lighter to be hot, so I quickly shook off the fire, endured it in the dark for a while, and once again turned on the lighter and looked around.

Look left and right, there are really a lot of good things in this waste mine, and there are a lot of wood piled up under my feet, I don't know when it floated up, and it has already dried up.

These things can be used as fuel to burn a fire, otherwise my lighter won't last long.

Also, the tin trolley next to me looks pretty good, and I'll pile some more in it.

Make a torch that can float on the water, I pushed this torch boat away in the water, Zhong Bai saw it from afar, besides, the key is that the burning fire can disperse something.

Actually, I'm not so scared now.

It's just that I'm a little worried about Zhong Bai.

I stirred up a pile of dry firewood, lit a fire, and by the light of the fire, I gritted my teeth and pushed the cart over.

I didn't pay attention to it just now, but I suddenly got out of the water just now, only to find that the sea water in this cave is colder than the sea water outside, cold and biting, and the cold air is like it is about to penetrate into people's bones.

I didn't care about the fire to keep warm, so I quickly emptied the water in the cart, put a pile of dry wood underneath, lit the fire, and finally pressed a few large logs on it, and the big wood was burned, and it was no problem to burn these few big pieces of wood for a few hours.

After doing this, I put my mind at ease, warmed my hands by roasting on the fire, and then gritted my teeth, waded into the water, and pushed the small cart forward.

The trolley was quickly heated up in icy water.

Pushing a hot cart, I quickly felt the cruelty of ice and fire, the water was cold, and the cart was hot to death.

The fire was blazing, illuminating the cave red, and there were broken pillars and collapsed brick walls everywhere, and some rattan baskets that were so rotten that they could be seen beneath them.

Rusty shovels, iron basins, I am also a little strange, this is obviously still on the sea, how can there be such a large abandoned mine, could it be that this mine was built under the sea back then, how many good things must be under it, it is worth such a toss?

It was unusually cold underwater, and I pushed the cart for a while, and I was so cold that my teeth were fighting, and I couldn't stand it anymore, so I quickly pushed the cart to the shore, climbed ashore myself, and baked the fire against the cart.

But after a while, I suddenly felt that something was wrong.
