After Traveling Back and Forth for Thousands of Years, I Actually Built Wolf Academy!

Chen Qian, who accidentally traveled to the world of Harry Potter, wanted to be a peaceful little wizard, but he didn't want to be sorted into the Witcher Academy by the Sorting Hat on the first day of school! That night, he traveled through time again, to a thousand years ago, and met Ravenclaw when she was still a little girl. When others learn magic, he applies sword oil; when others wave their wands, he uses his seals. When Gryffindor and Slytherin were arguing about whether to recruit Muggle-born students, Chen Qian silently slapped the steel and silver swords on the table and hung the fifth courtyard flag in the most conspicuous place in the castle. The fifth school of Hogwarts, the Witcher School, was officially established. The house of lions represents bravery, the house of snakes represents ambition, the house of eagles represents wisdom, and the house of badgers represents loyalty. And the Wolf Court only represents one thing. When darkness strikes, they are the first in the entire castle to draw their swords!
