Feng shui master Chen Qingyang took over his grandfather's relics, but the bronze mirror was riddled with cracks. Corpses crawl on his neck every day and night, and only by solving the mystery of the centuries-old Yin Coffin can he survive. The living corpse carrying the coffin in the abandoned righteous village, the headless bride in the dead inn, the staking altar in the underground tomb... When the forty-nine soul-inducing lamps were turned on, he discovered the truth about the sudden death of the entire village twenty years ago. What is locked in the coffin is not only the evil ghost, but also the blood contract that the Chen family has carried for generations. With the seven-day countdown, can any living person escape this sacrifice that lasts for three hundred years?
