Shen Mu was once the most ordinary shadow in the world, until a bloody fog swallowed up his home. From then on, he embarked on a journey to return the evil spirit, holding in his hand a glass bone amber that is said to be able to awaken the memory of the dead. Whenever night falls and the moon's shadow is mottled, Shen Mu wanders among the claustrophobic alleys and abandoned shrines, searching for the lost contracts that stake his soul. His enemies are not only living people, but also nameless ghosts lingering in the underworld and the human world, trying to lure him into perdition with lies and illusions. And Shen Mu's revenge is not only repayment with swords and flesh, but also an interrogation of fate itself - when all the truth is hidden under the nightmare, who is the hunter and who is the sacrifice?
In this bloody journey where the soul and the body, the past and the future intersect, Shen Mu must find a way to send his soul home amid his ever-broken self, or become his own deepest shadow.
