An orphan who struck it rich overnight gathers seven strangers in Lujiazui for an immersive supernatural murder-mystery game. A copper bell rings, talismans burn to ash, and the group falls into a blood-red vision of a school haunted by the dead. Just as the survivors think the nightmare is over, they discover they have been caught up in a feud between brothers spanning several centuries: from a village corpse-raising ritual at a Republican-era Taoist temple to a showdown in the imperial palace during the Tianqi Explosion; from a rupture in time and space on the battlefield of the War of Resistance to a clash between yin and yang in the depths of the East China Sea. Forced to travel between real history and the netherworld, they struggle to survive amid guns, magic, and reincarnation. But it all comes to an end beside the Sea of Bitterness. Before the Hall of Yama, Dizang pleads on their behalf. They drink Meng Po's Soup and step through the gates of reincarnation, believing their past lives have been erased. Until they wake up at No. 7 Middle School on a rainy night. Their memories are shattered, their identities a mystery. The transfer student is sitting in the back row of the classroom, silently gazing out the window. The mark of the orphanage, his top-of-the-class grades, the ferocity he shows in a fight, and the strangely familiar poem, "Bone-Tempering Journey," that he wrote, all the clues silently cry out: the cataclysm that swept across yin and yang has never ended. This seemingly ordinary school is the final refuge for all their entangled fates, and the only place where the ultimate truth can be born. When a gift becomes a curse, and reincarnation becomes a prison, this time they must fight fate itself. (This novel blends infinite-loop suspense, historical transmigration, urban cultivation, the underworld, school-life rebirth, and other elements, weaving together five worlds: illusion, history, reality, the netherworld, and the living world.
