Inside the Black Corpse Demon Cave, the deeper one goes, the thicker the rising Black Corpse Demon Qi becomes, until one can hardly see their hand in front of their face.
Even with Huang Xiaolong exerting all three Great Holy Souls to their fullest, he can only sense within a ten-thousand-mile radius, while Chen Zhi and Li Jian Saint can sense an even smaller area.
A ten-thousand-mile radius is practically blindness.
In such a demon cave, with a constant terrifying howl reminiscent of both demon and ghost echoing, it involuntarily instills panic and fear.
Huang Xiaolong's eyes narrowed, realizing that these terrifying howls are actually emitted by some beings who were once strong in the saint realm but were later demonized.
