Three hundred years ago, the secret realm of the world of mortals trapped thousands of souls in the name of "overcoming sins", but they didn't know that this was a trap set up by Shen Qingfei, the Taoist of the world of mortals, to fight against the demons in the outside world. The abandoned disciples of various sects and mortal sinners fell into reincarnation, tempering the energy of the mortal world in the love and hatred of life and death, while the parasitic remnant soul of the demon in the body of Taoist Si Ming was quietly weaving a web that devoured human nature.
Lin Wantang, a medical girl who was falsely accused of exterminating her family, Xie Mingzhuo, a traitor of the Yuqing Sect who accidentally killed her master, Su Wanyue, a disciple of the Fenyang Sect who went into danger to save his master... When the five "sinners" met in reincarnation, the broken memories gradually spelled out the shocking truth: the secret realm is a cage and a battlefield; they are not only lambs to be slaughtered, but also the key to reverse the way of heaven.
When the bronze coffin of the Siming Platform is opened, when the remnant soul of Fairy Qingyao confronts the reincarnated person, and the darkness of the Heavenly Demon Fissure approaches the Star Continent, everyone bound by fate must make a choice - should they become pawns of heaven, or use their bones and blood as blades to break through this prison network woven with compassion?
In the purgatory of love, hate, anger and ignorance, some people hold swords to ask for love, and some people light up lamps to illuminate the night. When the last piece of red dust blends into the dawn, they understand: the deepest hell is never anywhere else, but in the blind pursuit of "correctness" in the human heart.
