Open Your Eyes and See Conan

When I opened my eyes, I saw a little devil wearing glasses. He was asking me for clues about the case. But I had no idea what was happening. The kid lowered his head, his glasses lit up, and I seemed to see a flash of lightning flashing behind him. The kid ignored me and quietly found a position where he thought no one else could see him. He opened his watch and aimed it at the mustachioed man's neck like a shooter, starting his bow-tie reasoning. Where should I go after watching the mystery show? If I guessed correctly, my identity should be a homeless person.
