Two Worlds: I studied abroad at Hogwarts

Came to Hogwarts from a low-magic world,
Moon was originally just a half-baked psychic with no talent.
But in this magic school, he received the best magic education.
......
Professor Flitwick of Charms: Scarlett, I am teaching you magic dueling, not dimensionality reduction attack.
Herbology Professor Sprout: Scarlett, I think you are more suitable to be a judge of the herbology competition rather than taking part in it yourself.
Transfiguration Professor McGonagall: Moon, I asked you to study Transfiguration, but I didn't ask you to transform something that doesn't exist in the world!
Potions Professor Snape: You must have more potion ingredients. Give them to me, give them all to me. This is the future of potions!
Dumbledore: Moon Scarlett, what is your secret?
Voldemort: No, I should live forever! I should rule the world! How could I possibly be his sparring partner!
......
When Moon graduated from Hogwarts, the Dark Lord had already disappeared inexplicably.
And facing the magical war in another world.
Moon has only one attitude:
Will you end the war yourselves, or will I end it for you?
