Chen Ya is the desperate night watchman in the deepest part of the city. He is as silent as a coffin, but he can see the truest despair of the dead. When Zhou Jin, a used bookseller, handed over a bleeding night shift diary, he realized that his sister's disappearance was just the tip of the iceberg. Lao Yan's lies, Bone Lady's obsession, Iron Throat's betrayal, and the mute boy's whispers, tear open the blood scabs of the Night Watch system layer by layer - this profession is not a guardian, but a sacrifice. Every night at midnight, the Yin pulse is restless, and the dead line up to knock on the door, and the next night watchman must be filled with the soul of a living person.
On the 47th night of vigil, Chen Ya discovered that Zhou Jin's blood talisman was hidden in his sister's relics, which triggered the resonance of the Yinjing. The White Bone Lady appeared in human form for the first time and asked for a 'new fetus'. Lao Yan secretly informed: Every generation of the Night Watch must devour the souls of their loved ones in order to seal the earth-line corpse tide. Zhou Jin took the opportunity to incite Chen Ya and revealed that Tie Miao was actually a traitor to the old system, with memory fragments of seven generations of night watchmen locked in his throat. The mute boy began to unconsciously copy Chen Ya's vigil movements, causing simultaneous changes in the three cemeteries. When Chen Ya was forced to choose between his sister's bones and the blood of a living person, Zhou Jin peeled off the human skin and revealed a face exactly like Chen Ya's - it turned out that the Night Watch contract was a cyclical self-sacrifice. And hidden in the ashes of Iron Throat are the last words of the 88th generation of the Night Watch: 'Don't choose him next. ' Long-term foreshadowing: The mute boy's true body is the remnant soul of the first generation of night watchmen, and deep in the Yin veins, someone is using the corpses of the seven Yin temples to reshape a living divine fetus.
