My Way Home Was Through Hell

To resurrect her parents, Su Jianong must survive three years as the unwanted daughter of a family that chooses their adopted child over her. After enduring prison and abuse, Jianong discovers that the supposed kidney donation is actually an organ-harvesting trap tied to Gu Jianuan's plan to murder the entire family for insurance money. She saves the people who betrayed her, completes her mission, and returns home, while they follow her across worlds seeking a forgiveness they can never earn.
