The goddess general Jiang Qinlan of the powerful Tian Sheng Empire and her soldiers are ambushed and killed. Her father dies a tragic death. After her death, Jiang Qinlan transmigrates ten years into the future, into the body of Bai Jinhuan, a commandery princess of the neighboring Great Yan and daughter of the Marquis of Zhenyuan. She inherits the original owner's memories, but her heart is set on avenging the blood feud from her past life.
Bai Jinhuan is timid and often bullied. Because the prime minister's illegitimate daughter, Su Xueruo, is in love with the Seventh Prince, Bai Jinhuan grows close to him. Jealous, Su Xueruo deliberately frames her, and Bai Jinhuan dies outside the city.
The Marquis of Zhenyuan and his wife died young, leaving little Bai Jinhuan in the care of a wet nurse. The wet nurse is wicked and ambitious: she embezzles the marquisate's private farmland and shops, murders the loyal accountant, and replaces all the household's important staff with her own people.
After Jiang Qinlan takes over Bai Jinhuan's body, she gradually embraces all that comes with it, cleans house at the estate, and keeps the loyal old retainers.
Yan Changning, the Seventh Prince, is the youngest son of the Great Yan emperor. Mischievous but exceptionally kind, he has known Bai Jinhuan since childhood and has always treated her well. But after Bai Jinhuan is led astray by Su Xueruo of the Prime Minister's residence, she grows to dislike the Seventh Prince, and the two rarely see each other.
Now in Bai Jinhuan's body, Jiang Qinlan remembers how kind the Seventh Prince was to her and goes to his residence to find him. They arrange to meet at a teahouse, and he is delighted to see her. He lends her his personal guards and agrees to help investigate the estate's hidden accounts.
With the Seventh Prince's guards, Bai Jinhuan joins the prince in driving everyone with ulterior motives out of the marquisate. The wet nurse and several servants are thrown into prison.
And everything Bai Jinhuan does is being watched by someone.
