Shen Bai, a famous young nobleman from the capital, was thrown into the obscure small city of Biancheng to be the magistrate of the county. In order not to let his days be too boring, he hired a strange young man named Lu Yuanqing, who aroused his curiosity, to be the official's counselor. With Lu Yuanqing's help, Shen Bai repeatedly solved strange cases: A naked female corpse can actually lead to two unsolved cases from years ago; a much sought-after book can actually claim lives in a series of murders; a long-grievanced ancient sword can mysteriously unsheathe itself and claim the lives of the Four Young Masters of the capital; and a woman who suddenly comes to the door claiming to be a relative was actually stillborn twenty years ago. While solving these mysterious murders, Shen Bai is also intrigued by Lu Yuanqing's mysterious identity, and the truth is even more unbelievable!
