Detective Chunyang and the Pawn Shop Owner

In the 26th year of the Republic of China, the Shanghai beach was filled with rain and fog. The "Xuanqing Pawn Shop" on Yinyang Street hid an unknown secret - what was pawned here was never gold and silver jewelry, but people's obsession, longevity and blessings. Bagua copper coins were used as tokens and followed the iron law of equal exchange. Detective Lu Jingming, who returned from studying abroad, encountered three bizarre murder cases: a wealthy businessman died of fright in a vault, an actor suffocated for no reason, and a coachman froze to death during the rainy season. The dead people all had gossip money from Xuanqing Pawn Shop on their bodies. Having always believed in science, he was forced to step into this gloomy old house and met the cold and arrogant pawn shop owner Shen Yanci, who always looked thirty years old, and the psychic black cat Ajiu. Shen Yanci revealed that although the pawn transaction had backlash, it was by no means fatal. The three murder cases were actually the result of someone using heresy to catalyze evil spirits and use obsession as a guide to take people's lives. In order to find out the mastermind behind the scenes, Lu Jingming, who exorcises pure yang evil spirits, and Shen Yanci, who masters the secrets of Taoism, formed a strange alliance. One person used criminal investigation methods to track clues, the other used mystical skills to decipher the evil spirits, and Ah Jiu used psychic powers to sense the traces of evil spirits. They walked between the bustling French Concession and the gloomy and dilapidated Yin Yang Street, uncovering past transactions entangled with obsessions and facing the greed and malice deep in people's hearts. As the investigation deepens, it is not only discovered that the target of the mastermind behind the scenes is the secret inheritance of Xuanqing Pawn Shop, but also involves a grudge dispute that spans decades. At the edge of the boundary between yin and yang, the two must not only fight against the evil magic, but also resolve the cognitive gap between each other, find the truth in the fog, and protect justice in danger.
