Feyel's movements had no discernible pattern, so all Yang Yi needed was the moment the door opened to confirm whether the person coming out was Feyel or not. After two hours of intently staring at the same door, the moment it finally opened, Yang Yi truly felt caught off guard.
To open the door and walk out was the normal choice for any person.
Yang Yi was momentarily distracted, but his right hand instinctively steadied the gun.
The barrel had already been adjusted; all Yang Yi needed to do was pull the trigger, and the bullet would fly towards the spot he had chosen, provided he confirmed the person exiting was Feyel.
If it wasn't Feyel, even if the shot hit the target, it would be a failure for the entire operation, and who knew when they would have another chance to act.
The door was half-open when someone began to step out from inside.
Although the figure had not completely emerged, Yang Yi had already clearly identified the person through the scope.
