The fifth question. The second season of Meng Detective is an IP immersive reasoning reality show produced by iQiyi. In the fifth issue, the program activities were carried out with the theme of hunting crime diagrams. Each issue of the program is based on a classic IP, which restores, adapts, crosses and laughs the original drama clips. Seven guests formed an exploration group, and through plot doubts and high-energy games, they obtained clues, made counter-routine reasoning, and happily searched for the truth.
