Hogwarts: I am the power of purification

Dedicated to exploring the magic essence of the magic world, the Harry Potter world! + Clow Cards! Not brainless, no licking of the protagonist group, no heroine, no harem of women, I don't know how some people can be so lewd! ! ! ! I won't invent spells as logically as if my brain was kicked by a donkey when I see a woman, and a spell will not be born suddenly and inexplicably! The system capacity is limited, and the protagonist's own ability is higher than that of a little wizard of the same level! This is the first time I write a novel, and I simply want to write the magic world I want to see! If a mushroom cloud appears when Rowling casts an explosive spell, don't panic, it's a nuclear explosion! ! ! ...
