In a world filled with warriors, cultivators, and terrifying ghosts and demons, Su Mu is reborn into another world. His life simulator, meant to help him survive, becomes a death simulator instead. Death, however, is not the end, but a new beginning. Through countless simulations, he evolves into myriad demons: a blood-煞 skeleton, a drought corpse zombie, a fierce thunder ghost, and an immortal ghost chariot. While some cultivate to become immortals, others become demons through countless deaths.
