Delivery boy Lin Feng was an ordinary person in the city who was inconspicuous. He traveled through the streets and alleys to deliver food every day, but he was accidentally bound to the "Detective System" while delivering food on a rainy night. The condition for system activation is to solve a real murder case. Successfully solving the case can unlock reasoning skills, clairvoyance, micro-expression interpretation and other props. Failure to do so will result in system punishment.
From then on, Lin Feng's food delivery road turned into a detective road - a poisoning in a secret room in an office building, a fake fall from a building in an old neighborhood, a delayed murder in a suburban villa, a murder in an internet celebrity's bed and breakfast... Every time he delivers food, he may encounter a brain-burning murder. He used the concealment of the deliveryman's identity to go deep into the crime scene, and relied on system assistance to restore the classic Conan-style murder techniques: replicating the "delayed poisoning with ice cubes", "fishing line secret room layout", "recording pen to create alibi" and other tricks. When the police were helpless, he uncovered the real murderer from the clues.
Faced with the murderer's perfect disguise, the complicated relationships between the characters, and the police's doubts, Lin Feng had to take care of his food delivery livelihood while using his extraordinary powers of observation and system tools to solve the puzzle. Each case directly touches on the darkness of human nature, from revenge caused by workplace bullying to the conspiracy of a mysterious organization. Lin Feng continues to grow in the process of solving the case, transforming from an ignorant "part-time detective" to a hidden force guarding the city's justice, and the secrets behind the system gradually surface.
