Zhang Fei Xuan excelled in controlling blood qi, and upon it, he refined an artifact capable of suppressing just that.
Wang Qizheng specialized in bone manipulation. The more formidable the enemy's physique, the stronger Black Mountain would become, and during suppression, it could also absorb the physical bones and physique of others.
Gao Sishu was adept in medical poison, thus after refining Black Mountain, he incorporated an effect that weakened others. It wasn't simply adding toxins, but rather removing the immunity from a person's body, causing them to become frail.
Lingdang added a cursing power into it, ensuring those suppressed couldn't move, their divine souls ensnared by the curse, their consciousness bewildered and disoriented.
Based on their estimations, even an Earthly Immortal would have a hard time facing their Black Mountain.
This was their reliance.
