Neil was surprised. "How did you know I would come?"
Xu Cheng: "Ever since I left the police HQ, you had been following me. I've been back in my home for an hour now, and I also know why it took you an hour to come up. You needed to make preparations for the perfect assassination and evacuation. You already checked this building's monitoring system, and half an hour ago, you pretended to be a delivery guy and went and knocked out the security guards before you turned off all the surveillance cameras. Then, you took the master key from the security guards, rode the elevator up, and locked the doors to all the stairways. You are wearing gloves so you don't plan to leave any evidence behind."
