Hogwarts: the Dark Lord Is Me?

Ling Yun came to the world of Harry Potter, only to find that he arrived early, before the Iron Triangle was born, and he became Voldemort's classmate. To ensure your own safety. During seven years of studying at Hogwarts. Ling Yun suppressed and subdued Voldemort, Hagrid and others, began to reform the Ministry of Magic, and rectified the Auror force! When he was asked by Voldemort when he would start to unify Europe. Is he still confused? Ling Yun: "Why do you think I have such ambitions?" Voldemort: "You said that in order to keep a low profile, let us cast a spell on your name so that no one would dare to call you by your first name." Hagrid: "You asked me to conquer the giant tribe!" Professor McGonagall: "You approved the Aurors to use the Unforgivable Curse! You also invented the three-piece Auror Warfare Set!" Professor Slughorn: "England's wizarding population has doubled, and we're ready to attack!" Grindelwald: "Your ideas are a hundred times greater than mine!" Dumbledore: "Perhaps... Unifying the magical world will allow wizards to usher in true peace!" Iron Triangle: "Look, it's the iron-fisted leader Mr. Ling Yun. He created the real era of magic!" Only then did Ling Yun realize that the Dark Lord turned out to be himself! ! !
