The underwater tunnel shot straight down like a drainage well, the space a bit cramped. As I swam, I felt it might really be a drainage well. Above it, rocks pressed down as if naturally formed, but the lower part of the tunnel was man-made, the stones smooth and carved with patterns.
This was not a spring at all, but a corner of an Ancient Ruins. I descended more than ten meters before stumbling upon a door.
When my hands touched the door, my palms went right through, followed by my entire body. Only after entering did I feel surprised because inside it was dry with air, just like being on land.
The water outside hadn't come in at all, except for the drops that fell from me.
Beneath lay an unexpected world. I looked around and found that it was a... tomb!
A tomb built into a drainage channel, quite creative. I stared at the coffin placed in the center, noting the wet handprints on its lid.
"Doctor Du?!" I called out.
