The heroine Jiang Wan crosses into a book, becoming the only daughter of a general's household and the vicious mistress of the Marquis's estate. The original owner was a love brain, bullied by Marquis Pei Jingxing, and acted as his tool to persecute the concubines, ultimately being stripped of her family's wealth and ruined. After waking up, Jiang Wan saves Shen Rubι, and subsequently wins over Liu Ruyan, Lin Qingdai, Zhao Feiluan, and Xiaoman. The five women each possess their own businesses and unique skills: salt trade, embroidery, medical skills, restaurants, and singing voices. They transform from contending for favor into forming an alliance, cutting off Pei Jingxing's commercial routes, palace connections, human networks, intelligence channels, and hidden operatives, exposing crimes such as seizing family wealth, taking lives, destroying marriages, and framing loyal officials. Pei Jingxing is stripped of his peerage, his family's property confiscated, and he is imprisoned, while the five women each fulfill their dreams.
