Hogwarts' Zaun Dharma God System

Traveling through time and becoming the last bloodline of the Grindelwald family, I originally wanted to keep a low profile and survive, but I was forced to bind to the "underworld law god system". From then on, the style of Hogwarts completely went off the rails. "All petrified? That's too low. Come and see the power of our Zu'an petrified!" "Want to learn the Patronus Charm? Pay a protection fee to the system boss first, and Avada can turn it into a rainbow for you even if you bite a big melon." Dumbledore looked at the savior who had been developed into "Ponyboy" and fell into deep thought: "This kid... Maybe he can form the most cowardly villain alliance in history with Tom?" Until one day, I was cornered by the Dark Lord, and the system suddenly prompted - "Brother, there is a person across from you, shake him down and fuck him!"
