**"Scumbag Identification System" + "Legal Pioneer of the Republic of China"** is a cool article about a heroine starting a business. The heroine has no metaphysical ability, her "divination" is psychology + information gap; her "talisman" is physical evidence. She runs a "marriage rights protection firm" that specializes in helping women collect evidence of scumbag men's crimes, fight divorce cases, and break the shackles of feudal marriages. The novel is an epic about women's resistance to oppression in the Republic of China. All unit stories are closely related to the social phenomena of the time (such as concubinage, wife pawns, and pre-marital body examinations). The main line is the story of how the heroine climbed out of a marriage that was buried alive and used the law and wisdom to seek revenge.
