When the Hulk Broke into Hogwarts

Harry Potter, Hogwarts, Hulk templates... Bad news: I inherited a huge amount of assets from my distant cousin and was sent away by a dump truck on the road. Good news, time travel! What I wore was the book I had read! A better news, the system is coming! No, what does it mean to come to the wrong world? What does it mean to kidnap the wrong person? Leave me a Hulk template subsystem and run away? The sky is falling! In this magical world, how can I, a fist-fighting man who is purely a physical practitioner, survive!
