The legitimate daughter of the Marquis of Zhennan, Luo Ning, was persecuted to death in her previous life by her mother, Madam Bai, and her cousin Bai Cirong. After being reborn, she used her wisdom to seek revenge, first eliminating the mountain bandits, then leveraging the Empress Dowager's trust to return to the marquis's residence and strike back. With the help of Prince Yong, Xiao Huaifeng, she repeatedly exposed the schemes of Lady Bai and others. In the end, Luo Ning revealed the truth, successfully avenged herself, married into the Prince Yong's mansion, and began a new life.
