Marrying a Dandy, Reborn as a Mistress and Overthrowing the Duke's Palace

In the previous life, Qi Yu and his sister-in-law Qi Yanran married into the Duke of Wei. She married her young father-in-law Wei Xun, and her sister-in-law married Wei Zheng, a dandy from the second wife's house. She was in charge of the family, loved her sister-in-law, and even agreed to allow Wei Xun to have two wives after Wei Zheng's death. But she had nothing to do for five years, while Qi Yanran had a family full of children. It wasn't until the entire Qi family was slaughtered that she saw clearly the hypocritical true face of Wei Xun, the person beside her. Her sister-in-law, whom she had doted on for many years, was also a fake daughter trying to occupy the magpie's nest. She did not hesitate to die with the two of them. Once he was reborn, he and Wei Xun were both reborn on their wedding day. Wei Xun changed brides and married Qi Yanran. Qi Yu made a mistake and married Wei Zheng, his dandy uncle-in-law who died early in his previous life. Everyone laughs at her that the colorful phoenix follows the crow and the bright pearl secretly throws herself at her. Until later—— The romantic and dandy Wei Zheng discovered that her gentle and quiet wife killed people without batting an eye on a dark and windy night. The gentle and quiet Qi Yu discovered that his romantic and dandy husband was secretly stirring up trouble by pretending to be a gambler. The two of them exposed Qi Yanran's identity as a fake daughter, uncovered the mastermind behind the Duke's palace, and turned the palace upside down.
