The Mad Young Lady Returns to the Capital, and the Matriarch System Fails

Everyone knows that Chu Hengwu, the eldest daughter of Minister Chu, is a madwoman. She spent eight years being tormented at the Chu family's old residence in Qingyang. Eight years later, she was brought back only to marry in place of her younger sister, Chu Fuxue, to the paralyzed and violent heir of the Marquis of Yongchang's household. The Chu family assumed that after eight years of torment at the old residence, she would be timid and docile, and that a little coaxing or intimidation would make her obey. They never expected that her gentleness was an act. The ferocity inside her had never changed. Chu Hengwu returned with just one purpose: to reclaim, one by one, everything that had been taken from her. Not a single person who owes her will escape. The “System” her dear mother relied on had once driven her into a desperate corner. But now she has found a way to counter it. Everything is under control, except At the palace banquet, she sees her brother Zhixing. Wasn't he a traveling merchant? Why is he standing before the emperor? Who is he, really?
