Backlight Plan

She is an undefeated criminal profiler who firmly believes that all evil stems from a twisted heart. He is a legendary detective in the police world, obsessed with restoring the truth with irrefutable evidence. A bizarre "mirror image murder case" forced Nan Xing and Gu Yuan to join forces. The deceased was placed in a strange symmetrical posture, and no trace could be found at the scene. Nan Xing believed that this was the murderer completing some kind of paranoid ritual, but Gu Yuan captured a familiar and strange pattern from the most easily overlooked details. As the investigation deepens, each crime scene is like a logical puzzle, and the answer vaguely points to a memory that Nan Xing forgot three years ago. What is even more shocking is that Gu Yuan discovered that what they were tracking was not a person, but a "system" that could accurately predict their every move. When scientific logic cannot explain, when Nanxing realizes that he may be the last link, they must face the "backlight" that can subvert everything in the maze of memory, on the boundary of mutual testing and trust.
