After Arthur was led away in critical condition by the police, Michael went to Han's car to check. Suddenly he saw the switch Arthur mentioned next to the car's accelerator. He looked around until he was sure no one saw his action, then bent down to pick it up, looking at it subtly, sneakily, and attentively. After a few minutes of staring at it, he saw that it looked like a bomb switch. Suddenly, he noticed the appearance of an inspector, quickly approaching him after chatting with the crime scene staff for a while. Michael quickly put the switch in the inside pocket of his suit, regained his composure, and raised his face with poise. When he looked at the inspector, he smiled brightly and looked at the inspector.
