Start in Jail: Help! Being Assigned to Azkaban

Travel through the world of Harry Potter and enroll in Hogwarts. I wanted to develop secretly, take away the magic stone, and gain immortality. Put on the sorting hat. The next moment, it screamed in terror: "Azkaban!" Azkaban, the most terrifying magical prison in history! "???" Confused. Enrollment turns into jail. When you encounter the cell head Soul Eater, the system is activated. I farmed Soul Eater like crazy and kept leveling up! Soon after, the Soul Eaters trembled. I wanted to be a hero, but sorry, I want to be a devil. The second generation Lord Voldemort sneered: "How dare you become king now?... No! Don't destroy my Horcrux!" The first generation Grindelwald said with respect: "He is the greatest wizard in the world!" Dumbledore: "He is the most terrifying demon!" Hermione: "I have to work hard to become his right-hand man!" This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
