The reason Yan Ao had gathered all the bosses and employees of the scam park here was naturally not because he had a sudden surge of a sense of justice to rid the world of these demons. Rather, he intended to use this opportunity to try practicing a new skill.
Blood-Dissolving Dharma-Extinguishing, skill level LV1. After practicing, it allows one to manipulate blood for attack and defense...
This skill was the one Yan Ao inherited from Bao Junfei when he killed him. Unlike ordinary skills, despite its level being only LV1, it shared a trait with the Spirit Refining Art: both could acquire powerful strength through self-cultivation. It was precisely because he valued this point that Yan Ao chose to inherit the skill.
