บท 70: Elemental Perception: Water

Centipede Cavern was located across a terrain that was generally underlain by limestone. It was in the belly of the mountain, where everything was completely made of rocks. The interior of the cavern was vast. There were also jagged rocks of grotesque shapes all over the place. However, nothing about the cavern's surroundings looked messy. Looking up, there were ten tunnels, and each of them had a width of approximately two meters. These tunnels were obviously formed from the movements of some sort of creature similar to a giant serpent. It had dug through the rocks, leaving trails and tunnels behind. It seemed that the friction between the surface of the creature's skin and the surface of the rock had left the surface of the walls strangely smooth and symmetrical. At first glance, the well-polished tunnels actually seemed more man-made.
