Leah Reed, after falling into water, is reborn and awakens the strongest survival check‑in system. She completely changes her former foolish and timid self. In her previous life, she was cruelly tormented by her stepmother Irene Carter and her half‑sister Katie Reed, and was framed, leading to the tragic death of her entire family. In this life, she schemes step by step, publicly tears off their hypocritical masks, and boldly breaks off her absurd engagement with Prince Nathan Ashford (the Third Prince). She completes system tasks successively, gaining a poison‑immune constitution and various extraordinary opportunities. While investigating the old truth of her biological mother’s murder, she joins forces with Prince Owen Ashford (the Ninth Prince, known as Xiao Jue), who was poisoned and who had collected her body in her previous life.
