Collection of Folklore Stories

Zhao Zixuan, an ordinary urban white-collar worker, is busy with the trivial matters of work and life every day. However, one peaceful night, a letter with no postmark and no sender suddenly appeared in front of him, breaking his originally peaceful life. The cover of the letter was written with the words "Underworld Police Station" in ancient seal script. The writing was profound, as if it contained a mysterious power. Zhao Zixuan was full of doubts, but he couldn't help but open the letter. The content of the letter shocked him even more. The letter read: "You have been selected as a special adviser to the Underworld Police Department to assist us in investigating a major case involving the human world."
