The protagonist Qin Feng is a loser in the police force who is a "connected person" and is assigned to the backlog team to hang out. But he awakened the "All Things Listening System" and could hear the conversations of all inanimate objects within a ten-meter radius.
The beginning is at the scene of a serial murder case. Criminal investigation experts and forensic experts are quarreling with each other. Their analysis is sound but all wrong. As soon as the protagonist enters the door, he hears the ashtray on the table screaming: "Oh my god, the murderer wiped his nose on my base!" The wall clock on the wall is complaining: "That perverted fat guy in a raincoat looked at the deceased and laughed for half an hour at three o'clock last night. What a pervert!"
The protagonist ignored the inferences of all experts, went straight to the trash can, dug out key evidence, and pointed at the murderer disguised as a reporter in the crowd: "Stop pretending, the patterns on your underwear are exactly the same as those left on the nails of the deceased."
The whole audience was shocked. The protagonist not only solves crimes like drinking water, but also digs out the secrets of wealthy families and dirty information in the entertainment industry through the "gossip" of items. There is no complicated reasoning process, only the simple and crude truth. What the murderer thinks is a seamless plot turns out to be a joke in the eyes of the protagonist.
