The Dark Lord System at Hogwarts

Nok, male, eleven years old. A time traveler, an orphan, with no bad habits. Ideal: Be a respected white wizard, find a stable job after graduation, marry a gentle wife, and raise an owl. Reality: The Ministry of Magic sent three Aurors to kill him on the grounds that "you and Voldemort lived in the same orphanage." When he was about to die, a system jumped out. Bite! Congratulations to the host for activating the Dark Lord cultivation system! [Goal: Become a man who makes the entire magical world tremble! Nok: "... I just want to be a white wizard, why do you bind me with such a dirty thing??" [Task 1: Survive. Knock survived. [Task 2: Make those who hunt you pay the price. Knock: "... I was just acting in self-defense." [Task 3: Build your power. Nok looked at the giant dragon, centaur tribe, vampire army, and KD army behind him: "... They are just my friends." Many years later, Voldemort returned from resurrection and heard that there was a guy "darker than the Dark Lord" in Hogwarts. He found Nok and prepared to join forces to rule the world. Nok sighed and took out his wand: "I repeat, I just want to be a good person."
