Jia Feng, the ancestor of Xuanmen, accidentally passed through the book and became the vicious female supporting character in the novel about rich and powerful families. The beginning was hell mode: she was blacklisted by the whole network, abandoned by her family, falsely accused of mental illness, and bound to a system that forced her to "do good". Jia Feng tore up the script, ignored the system, and reopened a century-old pawn shop on the ruins that specialized in "underworld" business. She pawned her grievances, traded obsessions, and used thousands of ghosts as chess pieces to stir up the turmoil in Beijing. During the day, she is the "broom star" that everyone avoids; at night, she is the owner of the "Mystery Shop" that is feared by ghosts and gods in the three realms. While dealing with the male and female protagonists of the original book and various Xuanmen forces, she was tied up with the sinister villain Luan Yang, the young master of Xuanmen who was supposed to be her biggest enemy, because of an old marriage contract. The two went from being a contracted couple who tested each other to becoming soul mates fighting side by side, and finally uncovered the dusty fateful entanglement. With her absolute strength, Jia Feng slapped everyone who looked down upon her in the face. From being an abandoned daughter of a wealthy family, she counterattacked and became a Taoist preacher, creating her own legend with her own hands.
