At the bottom of the water was a series of traps made of stone and wood, densely packed under the water.
Why were there so many traps at the bottom of an undercurrent river?
Yun Qin instantly felt her hair stand on end. Normally, traps in places with such a long history were either used to hide things or bury the dead.
In short, they were all related to "tombs".
From the looks of it, the headstone at the entrance of the cave was not a landmark or reminder, but a marker that recorded the identity of the deceased.
However, when Yun Qin turned on her flashlight, the scene in front of her shocked her so much that she almost forgot to breathe.
Unlike the long underground river tunnel, the cave in front of her was incredibly huge.
Looking up, the height of the cave seemed to be higher than the distance Yun Qin traveled down the mountain into the valley. She couldn't see the ceiling even if she was using her flashlight.
