The pinnacle of Chinese classical mystery novels! During the Tang Dynasty, strange cases occurred one after another: an abandoned house with ghosts crying late at night, an official who died suddenly and mysteriously, secret letters hiding mysteries... The clues were intertwined like spider threads, and the truth was covered up by layers of fog. Di Renjie uses a pair of insightful eyes to see through people's hearts, see through the disguise in the details, and solve the puzzle in the weirdness.
