Black Heart Lotus Seduced the Regent with Her Words and Autopsy.

Su Yan, a modern criminal investigation expert and forensic genius, is a foolish legitimate daughter who was bullied in the Anping Marquis Mansion of the Great Yong Dynasty after a plane crash. The first thing he did when he woke up was: he slapped his stepmother in the face with a backhand set of "Dayong Rules", dismantled his scumbag father's misappropriation of dowry in public, and scolded his playboy fiancé to the point of regretting the marriage on the spot - "How dare you go out with an eight-in-one figure?" A woman named "Su Yan" disguised herself as a man, and used her modern autopsy skills to solve strange cases: poison dripping from the ice silk ceiling, the secret room with flying knives on the Tongque Terrace, the frame-up of blood sacrifices in the Imperial Ancestral Temple... Each case led to the fall of the powerful regent Xiao Jue step by step. However, Xiao Jue only thought that Su Yan was a handsome man. While he was fascinated by her, he also painfully suspected that he had broken his sleeves; the silly guard Feng Yan cried out "The prince is finished" every day, making him full of jokes. She relied on talk and autopsy to run amok in Dayong, until the day her identity was revealed, Xiao Jue held her hand with relief: "My sleeves are not cut off - the person I like happens to be you." From then on, the legend of the "Iron-mouthed Princess" and the "Black-faced Regent" appeared in the court, and Su Yan's modern golden sayings became the "Old Yan Says" on the lips of the people of Dayong.
