Hogwarts: I Am The Only One Who Is A Cultivator

"Ye Feng! How many times have I told you that you are not allowed to use sword control to control flying broomsticks! You are not allowed to steal Hermione's wand and use your own wand as chopsticks!"

This is a story about a time-traveler who single-handedly distorts the style of Hogwarts; this is a story that makes the top brass of Hogwarts madly change the school rules just to restrict our protagonist; this... should be an interesting story.
