Su Xiangwan was once a mathematical prodigy who could solve mathematical problems that made significant contributions to aircraft carrier research and development. She was also the long-lost biological daughter of the Su family. After her parents brought her back home, they looked down on her because she came from the countryside, had an ordinary appearance, and behaved crudely. Her status in the family was nowhere near that of their adopted daughter, Su Qingqing. To secure her position in the Su family, Su Qingqing secretly framed Su Xiangwan time and again. The entire family blindly believed her lies. Even during an examination, when it was clearly Su Qingqing who had copied Su Xiangwan's answers, her father publicly beat and berated Su Xiangwan instead. Lying in a pool of blood, she watched her cold-hearted family. If she were ever given another chance at life, she would make sure they paid for everything.
