The modern queen of law accidentally slipped into a sadomasochism novel set in the Northern Song Dynasty, and became a vicious female partner in the book who grew hateful due to love and had a tragic ending. The original owner was the substitute for Bai Yueguang in the heart of Zhao Mingxuan, the son of a powerful man. After being married home, he was treated coldly and framed, and was eventually abandoned, disfigured, and died tragically. The heroine, who is familiar with the plot, refuses to follow the original plot. She relies on her legal knowledge, business acumen and top-notch negotiation skills in modern society. In the Northern Song Dynasty, when the status of women was low and the laws were strict, she cleverly used the "Song Xingtong" and other laws to break the situation starting from the internal struggle. She first used the "seven outs" rule to collect evidence in reverse, sued her husband for "divorcing his wife without cause", and successfully "divorced" her husband. Then she used her slight understanding of historical trends to start selling food at a stall, establish a restaurant, get involved in shipping spices, and accumulate huge wealth. She specializes in litigating cases for wronged women and civilians, and has repeatedly solved strange cases, gaining a reputation in the male-dominated litigation industry. During this period, she kept dealing with the scumbag ex-husband who woke up and tried to win back, the upright officials who appreciated her talents, and the business opponents who were wary of her abilities. In the end, she not only changed her own destiny, but also promoted a series of case verdicts that were beneficial to women's rights, becoming a legend in the Northern Song Dynasty.
