Hogwarts: I Am the White Devil, and I Love Teaching

After transmigrating to the world of Hogwarts, Arthur awakens the White Mage Mentor System.

He can earn rewards by answering other people's questions, discovering their potential, and guiding them to mend their ways and follow the right path.

And so Hogwarts is transformed from then on:

Harry starts loving his studies, stops getting into trouble, and works hard to improve himself;

Neville overcomes his fears, abandons his wand for a sword, and becomes a battle mage;

Seamus delves into his potential and makes a name for himself in the wizarding world as a demolition mage;

Death Eaters turn over a new leaf, work hard to reform, and devote themselves to studying;

Arthur: "I believe there are no bad students and no dark wizards. They only turn out that way because they never had a good teacher. With me as their mentor, they'll all become students who love to learn."

In abandoned Azkaban, the Dark Lord, now without any followers: "Yeah, yeah, you're absolutely right. Could you put your wand down now?"
