It was extremely obvious that this cave had been dug out artificially. It had been dug out in an extremely methodical manner, and various markings that looked like fish scales could be seen on the walls. There were also some diagrams and some writing that had been left behind on the cave walls, and the cave itself emanated a strange intent that felt like flowing water. Ji Ning couldn't help but be affected by the cave's aura, and his heart became quite calm as well.
Ning was in no rush to read the words or look at the pictures. Instead, he first carefully inspected the scale-like patterns and marks on the walls.
"Very neat."
"If someone slowly dug the cave out, there's no way it could all be so neat and tiny." Ning stared at the tiny markings. "I feel as though someone must've used a divine ability to instantly scoop out the rock and make the cave."
Ning couldn't help but feel shocked by this possibility.
