Jiang Yiyuan used to be a broker in the Underworld, earning rewards by hunting down the evil spirits who escaped its grasp.
After an accidental car crash, he returned to the world of the living in someone else's body and gained the ability to sense the past of spirits.
Some died tragically, their lingering resentment stirring up trouble among the living.
Some were trapped by regrets, wandering the human world for a hundred years without being reincarnated.
Some would rather have their souls obliterated than give up seeking the truth and justice they deserved.
He used to hunt only evil spirits. Now he takes on requests from the dead, helping wronged souls clear their names, letting regretful souls put their affairs to rest, and helping those who died with grievances obtain justice.
Theme: Everything has its cracks. That's where the light gets in.
