Born into a family of goldsmiths, Fu Rong is a smart and studious girl. After witnessing her sister's unfortunate marriage, she vowed to be self-reliant and independent, never to follow the crowd, and to control her own destiny. She escaped from her marriage and came to the capital, where she met the arrogant Su Wang Xu Jin by chance at a garden poetry party. The two experienced life and death together, found out the truth of the gold murder case, arrested Cheng Wang Xu Mao, who privately made weapons, and found out the real murderer who poisoned Concubine Duan. Fu Rong won Xu Jin's sincere admiration with her extraordinary knowledge, kind character and self-improvement, and Xu Jin rescued Fu Rong many times in critical moments. When Fu Rong suffered the grief of her mentor Liu Qingzhu committing suicide, Xu Jin encouraged Fu Rong to cheer up and work together to find the real murderer behind the scenes. Fu Rong discovered the rebellion plan of the emperor's uncle Xu Ping during the disaster relief, and used the jasper gold hairpin to find Xu Ping's secret room, and finally forced Xu Ping to commit suicide. After experiencing a series of life changes, Fu Rong and Xu Jin became indifferent to fame and fortune, returned to their homeland together, and lived a happy life of knowing each other and staying together.
