Intern forensic doctor Gu Chen accidentally activates the academic system because of his mother's unsolved case - reading criminal investigation books can be directly converted into skill points, unlocking talents such as photographic memory, trace examination master, and psychological profiling. As a "humanoid evidence library", he partners with Su Wanqiu, a gentle forensic assistant, and starts from small cases such as campus falling cases and community secret room murder cases, and gradually solves serious cases such as the "Rainy Night Butcher" serial case and cultural relic theft cases, and finally reveals the network of evil forces behind his mother's death.
