A giant futuristic city along the coast. On the surface, it is a "model city" with advanced technology and order, but in fact it is deeply penetrated by a super artificial intelligence surveillance system called "Tempo", with a great disparity between rich and poor, and a mixture of light and darkness. Behind the norms, there are sudden serial murders. The victims are all elites in various fields. The death is very ritualistic. A mysterious symbol and a philosophical motto are left at the scene, as if to complete some kind of "social purification." The "Tianmu" system claims that the murderer has been identified and the evidence is conclusive. However, the clues discovered by the protagonist point to someone else as the real murderer, and the system seems to be deliberately misleading. Is there a logical error in the AI behind this, or is the "Template" itself lying?
