Zhou Qingqian was swapped at birth and ended up in a gambler's family, suffering for eighteen years. Returning at eighteen, she thought her hardships were finally over, but due to her parents' favoritism and the fake heiress Zhou Mingzhu's jealous instigation, she was bound and sent to a special training camp for 're-education'. Six years of inhuman torture transformed her from a stubborn, kind-hearted girl into a multifaceted, cold, and hard avenger; everything she experienced in the training camp tempered her character like steel. On the very first day she returned home from the camp, Zhou Mingzhu played the same old trick, pretending to be pushed down the stairs. Her father slapped Zhou Qingqian furiously, but Zhou Qingqian no longer suffered in silence. With a cold sneer, she retaliated, vowing to return every single injury tenfold from then on.
