The white mist covered all visible areas. The seawater beneath him was a deep blue, and one could even see bubbles in the water.

John told me that he would return to the shore to replenish energy after we went into the water, and that he would return as soon as he was finished. It would take about two days, but in his estimation we'd be underwater a little longer.

I used my watch to locate the coordinates, then explained to him what it meant to wake him up.

Wei Yuting had also woken up. The three of them wore a thick layer of waterproof clothing, and with a flip, they dove into the water.

The seawater is strictly layered, with clear and opaque top and bottom parts. No fish here.

In my original plan, we would have to dive to the surface and quickly dive into the ground without flooding. However, there was a long tube beneath him, which made it so that he didn't need to spend so much effort on anything.

It's called a pipe, but it's actually thicker than me, and one end goes down so that I can't see the end, while the other end is tightly sealed.

This material was the most common type of stone. It was impossible to tell at all. There were two clumps of seaweed hanging from it, swaying unsteadily.

Wei Yuting and what was the purpose of the gathering? We adjusted our position a little and stuck our hands in the gap. He then moved it up diagonally.

It was hard to use force in the water, and I could only use my full strength by a small cut. The water flowed straight in, causing the lid to flip over. Wei Yuting was coincidentally in the back and was hit squarely in the back.

A suction force pulled me into the pipe. Wei Yuting slowly propped up the stone slab and waved it with one hand. I went in and walked down for a while. The water stopped flowing and I started falling straight down.

Fortunately, the stone tube was placed diagonally. When I fell to the ground, there were only some wet marks. The walls of the pipe were much better than before.

I quickly stepped aside. Wei Yuting and the rest of them came down as well, both of them in the same sorry state.

I couldn't tell if this was on the ground or underground. All I knew was that the four sides of the room were completely sealed, but when I struck a match, there was indeed oxygen.

I turned off the oxygen valve, took off my hood, and asked what it was.

"This time, I'll still be looking for the stone tablet." He said dejectedly, "But aside from this big environment, they didn't tell me what's really going on inside."

There was a long, narrow corridor in front of them, still moving downwards. I had located the place and was in touch with John, so the best thing to do at the moment was to walk with all three of us. It was pitch black down this long corridor, and the light from the flashlight was insufficient. He did not know what kind of scene was in the distance.

It would always be the same, with only a few appearances. I looked around, my eyes wide. It's not the same here.

It's like a sphere with a corner, and we're in between. Every cut surface had a spike sprouting out of it, and a disk was now pointing at me.

I was startled at first, but then I felt a little relieved at the thought that this was the only way down.

However, there was one thing that was strange.

The Maya know the circle, and you can often see similar shadows in drawings and digital applications. But what was frustrating was that even though they frequently used this kind of angular pattern in mathematics, they had never used a tool either in the construction of the pyramid or in the construction of it.

Call it a wheel.

In fact, it had been proved long ago in the trade that the Mayans knew about wheels and how to use them. But there was no sign of it.

That was one of the many reasons Maya was supposed to be one of the vassals of alien civilization. There was a saying that as long as they focused on mathematics, the rest were completely undeveloped. It was as if one aspect had turned on, while the other aspect was still gray.

In other words, there were no physical circles in Maya's things.

According to the places we've been before. Maya had a close relationship with China at that time and built underground buildings in China. But even so, they don't see any Chinese technology at all?

What was with this disk? Although I was not proficient enough to read, I could only make out the words, but they were carved in Mayan script.

The Chinese built it? Impossible.

This region was miles away from the Asian Plate. If he had this technology, then the Eastern Han Dynasty would have ruled over the entire continent.

I was at a loss, but reality only lasted for a moment.

What do you mean by going around to the thorn from the back, indicating that we really do not have the mechanism.

It was also because he was scared of the cold arrow earlier. However, at the bottom of the lake, the construction of such a large and bizarre building was already very good, and the details of the defense couldn't be counted on either.

But the road stopped here. There are no stone tablets here, and we don't believe it will stop so easily. Where is the secret door?

Wei Yuting called for us to go over. She was standing in front of a rock spike, pointing at it and saying, "A trace of water infiltration."

I looked down and saw that there was a groove beside the rock spike. It looked like it could be pulled out.

Wei Yuting was not at ease. She looked at all the stone spikes on the ground, a total of eighteen of them. The high ground was indistinct, but the six spikes on the ground were surrounded by a ring that seemed like they could be loosened.

We tried to put this aside and look for another entrance. However, the heavens are willing to not let us live, each big cut surface is a board. He looked up and down, left and right, but didn't find anything to pass through.

Then let's give it a try?

Putting on the diving suit, Wei Yuting squatted on the floor to watch, while I used my strength to grab the plate and pull it out. With a pull of the plate, the rock spike remains motionless. Just when I was wondering if I found the wrong place, Wei Yuting puts a hand to her mouth and tells us to remove the rock.

The stone and the ground were all soaked. If it was completely pulled out, it might be flooded again soon.

It seems to work. We tried them one by one, and of course we weren't in the mood for the top and the top eight. He placed his gaze on a stone spike that was slanted towards the entrance.
