Criminal Investigation: Tutor, Do the Cases I Solve Count as Credits?

Lu Li, a freshman in criminology at Haishi University, was personally invited to the murder scene by the criminal investigation captain on the first day of school. In front of the live broadcast camera, the murderer was arrogant and provocative. Lu Li typed calmly: "The window is not closed, the police car has arrived downstairs." The entire network witnessed the murderer being arrested on the spot. On the first day of school, a woman's body was found in the dormitory, and the police ruled that she committed suicide. Lu Li only glanced at it and pointed at the photo and concluded: "The deceased did not commit suicide. The murderer is male, 1.85 Meters tall, and his occupation is a baker." The suspect was arrested three days later, and the whole internet was in a frenzy: He even got the flavor of the cake baked by the murderer right! The serial case was restarted, and he left the criminal investigation competition midway. The housekeeper patted him on the shoulder: "Kid, stop investigating, it's dangerous." Lu Li grabbed his wrist with his backhand and said, "I have been investigating for three years and there are no clues, because you are the real murderer." Facing the experts' table-slamming questioning. Lu Li: "Crack the case? I usually take a nap - the answer has already been reported when I wake up."
