Hogwarts? I am coming! ——Elena Ravenclaw

(The author has made up many settings that are not in the original work. Of course, I will try not to conflict with the original work. If you feel there are problems with the settings, you can comment and the author will explain. If there are errors, I can correct them as soon as possible. Thank you everyone)
Concept: Everyday water can change the world
