Humans, demons, spirits, monsters, wandering immortals, and yin spirits all live among mortals.
The world is rife with supernatural cases, caused by resentment, obsession, demonic power, and vengeful energy. Ordinary people cannot solve them, and they can easily spark chaos.
Cultivators must resolve these cases and guide spirits to peace. In saving others, they save themselves. Only after their merit is complete can they ascend to immortality.
