During the Republic of China, the first five leaders of Du'e Zhai used blood as a guide and bronze medals as matchmakers to set up a century-old blood curse - to raise evil-devouring beasts that feed on obsessions. When the descendants of the bloodline of the five bronze medals return to their places, they will sacrifice their bodies and obsessions to help the evil-devouring beasts break the seal and turn the world into purgatory.
A hundred years later, five bronze medals were scattered in the world, leading to the fate of five descendants: Lin Yan, the owner of the antique restoration museum, was backlashed by the bronze medal of Lotus truncatula, and was cursed with a blood curse. He gradually darkened due to resentment and obsession; Chen Mo, the messenger of the Yinsha Station, was controlled by the bronze medal of Ouroboros and became a puppet in the fear of the midnight express; Late at night, he was devoured by the genealogy, and his blood and flesh merged into one, becoming the "living ink" of the sacrifice; Zhou Chen, the owner of the pawn shop of Evil Memory, was bewitched by the Taotie Bronze Medal, and used the Evil Memory as food, becoming half human and half demon, annihilating humanity; Zhao Lei, a late-night watchman at the unfinished construction site, was carrying the Earth Dragon bronze medal. In the conspiracy of shadow sacrifice, he witnessed the truth about his father's dead soul and the shadowless man.
Wrapped in fate, the five people gradually awakened their bloodline memories in the fight for the bronze medal, only to realize that they had been the "bait" set by Du'e Zhai since birth. When the five bronze medals gathered together, the calamity-devouring beast broke out, and the black fog enveloped the entire city. Obsession turned into a plague and spread. Humanity became a controlled killing machine. Shadowless people wandered the streets, devouring the last shadows and hope.
And this is not the end. The dead souls of the first generation of the five masters whisper in the black mist, and the babies of the descendants of the blood are born with the bronze mark. The blood curse of the hundred-year cycle of reincarnation is activated again. If obsession does not die, hell will last forever. This game of sacrifice and destruction will never end.
