Bai Wei couldn't help but ask softly, "Do the ghosts here... not devour each other?"

Randomly devouring Yin souls is a serious crime, punishable by being cast into hell at best, or having your soul scattered at worst. Of course, there's bound to be some underhanded dealings, but at least on the surface, rules must be followed."

Bai Wei understood, but more questions arose in her mind. "Then how do they cultivate? Where does the Yin energy come from?"
