Lin Zhao, as the "Zhenyintang" fortune teller who inherited his grandfather's legacy, has been involved in various supernatural incidents since he was a child because he can sense ghosts and identify the evil spirits of feng shui. After his grandfather passed away, he was forced to take over the task of "suppressing the underworld" and successively dealt with cases such as haunted houses, ghost markets, and family secrets. In the process, he met the thousand-year-old fox demon Su Qingli. As the investigation deepens, he discovers that behind the frequent supernatural events in the human world is a conspiracy by the ghost world to break the balance of yin and yang. The ghost world rebel "Yin Luo King" sealed by his grandfather is about to resurrect, and he is actually the "key" to the sealing ceremony that year. Lin Zhao, who has no golden finger, relied on his experience in physiognomy, logical reasoning and the help of his partners to gradually uncover the mystery of his life experience. Finally, he fought against King Yin Luo at the junction of Yin and Yang, and used the "Yin Suppressing Talisman" left by his grandfather to re-seal the ghost world and maintain peace in the world. Highlights: With "The Fortune Teller's Detective" as the core, it uses realistic supernatural details (such as the feng shui evil spirits in the haunted house and the ghost trade in the ghost market) to replace golden fingers. Through the growth of the protagonist (from forced responsibility to active guardianship) and emotional line (the bond between humans and monsters), the core theme of "yin and yang balance" is constructed, which is in line with the male channel's aesthetic of "responsibility and growth".
