HP: Become the Richest Man After Traveling Through Peter Pettigrew

Reborn as Peter Pettigrew, Fang Xu looked at the fat, timid face in the mirror and fell into deep thought. Will Voldemort be resurrected? Are the Death Eaters revolting? Dumbledore is playing chess? Sorry, he just wants to make money. Relying on his knowledge of finance and law in his previous life, he first bought real estate in Knockturn Alley at a low price, and then invented the "Magic Credit Card" and the "Quidditch Stock Index." Peter had already bought half of Diagon Alley when Voldemort came to him for a Horcrux loan. Snape: "Peter, your potion lasts better than Lily." Harry: "Uncle, can I advance next month's pocket money?" This is the story of a little man using the principles of economics to turn the entire magical world into a cash machine.
