Harry Potter Exchange System

What? A Maserati? Can I give you a bottle of 1982-year-old iced black tea? Hey, if you don't want to change it, then change it. Why are you scolding people? This is Guojiao who doesn't know the goods. Damn it, Star Destroyer Cannon? ? ? How about giving you a copy of "The Stars Are Calling", the second set of the Citizen Conjoined Exercises of the First Republic of the Universe? You can't exchange it for the loss, and you can't exchange it for being cheated. ———————————— This is the story of a happy poor orphan male protagonist who bravely breaks into Hogwarts with a broken system. Hope you will like it.
