After entering Wolf's Den, Ling didn't make any second thoughts to dash forward inside the cave. In his mind, his senses were way stronger than in the past so he could easily spot if there was a strong monster near him. Apart from that, the place was surrounded by gleaming stones that helped him to have a vision of the vicinity. Of course, the gleaming stones have a magic power that's why the light was emitted from them.
Moreover, Ling halted and paused for a second as he noticed the mana in this place was getting denser. To describe it, he could feel his body possessing a high magical power and his mind clearer than before. If that were the case, probably be a strong monster could be found in this place. Or maybe, a strange object located here that was surely the main source of mana.
