Chu Xisheng entered the cave and switched from the White Tiger Bloodline to the Vengeful Bloodline.
The "Blood Vengeance Illusion Ring," when not needed to simulate the blood of the White Tiger, could enhance the Vengeful Bloodline by two tiers.
At that moment, Chu Xisheng was unleashing the Vengeful Blade Intent of the eleventh layer, and the eleventh layer of the Vengeful Bloodline, which reflected and repelled all external power in the vicinity.
That included the dense "Death Fog" here.
Inside this cave, not a single blade of grass grew, with no living creatures to be found.
Not to mention the crickets and beetles common in dark environments, there weren't even any ferns or mosses.
Only numerous human and beast skeletons were scattered about the ground.
And the blackish-grey Qi Mist wafted and undulated throughout the cave.
This was the "Death Fog," a mist containing the power of death.
