[System + Live Broadcast + No CP + Protagonist Bon Voyage + Golden Retriever is the Protagonist] Today's news is on time!!! Shen Du, from the Liuhe Police Station in Jiangbin City, was a powerful forensic doctor in the serious crime team, but he was assassinated because he was resting at home on the weekend. His sister Shen Meng was a police officer in the serious crime team. Later, her leader Captain Li called her and told her that something had happened to her brother. She couldn't believe it. She almost fainted when she heard the news in the car. She was determined to find out who killed Shen Du. Unexpectedly, Shen Du's soul traveled through the body of a golden retriever she raised, and awakened a system for investigating and solving crimes. This system can turn him into a real person after he completes all the tasks. The crime squad has a new member - a golden retriever. It cannot speak and cannot perform anatomy tests, but its sense of smell is completely overpowered. It can accurately locate traces that others cannot find by smelling them. At every crime scene, Golden Retriever can always find decisive evidence and break the deadlock repeatedly. Prisoner: I clearly destroyed it completely! The golden retriever wagged his tail, thinking in his mind: Do you think you can hide it? The smell has already given you away.
