In the story and in your comments you say that the MC is ordinary and the only thing he has in his favor is the knowledge of the future but it is not so, personally I see him very different from someone normal leaving aside how calm he was when he woke up he is abnormal, the planning and movements that a normal person does could not do that even with the knowledge he has how calm he is in pressure situations. A normal person could not do that, the only thing I can think of is that it is when they brought him either by the body or by the being that brought him that something changed, am I wrong? personally I don't see a normal person achieving that.
