The five of them carefully flew down into the ravine. Wang Lin wasn't in front but to the right. While flying down, he was also observing the walls of the ravine.
The walls were extremely smooth; it was as if they had been cut by a sharp weapon. When Wang Lin's right hand touched the wall, he immediately felt a cold sensation enter his body through his fingers.
As the five continued to descend, the surroundings gradually darkened. However, this darkness was nothing to cultivators. They had celestial spiritual energy condensed in their eyes, allowing them to see everything.
The more they descended, more and more branching cracks began to appear, forming splitting paths like branches on a tree. Every branch was like a pitch black cave. Even with celestial spiritual energy condensed on their eyes, some caves were too dark to see into.
