As a ghost-catching master passed down for three generations, Jin Nuo has a natural sensitivity to resentment. Her grandfather was a famous master of metaphysics in the late Qing Dynasty and the early Republic of China. He specialized in yin and yang matters, saved countless wronged souls, and suppressed many evil ghosts. Jinnuo has been practicing metaphysics with his grandfather since he was a child. He has read all the ancient books and secrets in his family's collection, and is proficient in spells, formations, physiognomy, and psychic techniques. He has taken over his grandfather's mantle at a young age and has become a recognized top expert in the circle. It's just that she acts in a low-key manner, and ordinary people only think of her as a weirdo who likes to dress up in retro styles, but they don't know that this seemingly delicate "eldest lady" holds the key to the Yin and Yang worlds.
Her personality has always been changeable, and she meets many people. To the kind old man, she is a well-behaved and polite junior; to the difficult customers, she is a shrewd and difficult businessman; to the fierce evil spirits, she is a cold and decisive ghost slayer.
