Originally, I wanted to use the smell of police dogs to search for the whereabouts of Ma Fuyong's gold bars, but after Ma Fuyong got the gold bars, he washed away the smell of drugs with pepper water. It is easy for the horse to use the baby to escape the eyes and ears, and finally it is discovered by the iron egg.

Ma Fuyou was finally shot dead on the spot at the station. It was the gold bars that stimulated the central nervous system of the police dog and got out of control, which became the biggest clue.
