The Goddess of Fierce Battles and My Beautiful Senior Sister are both Xianxia and modern cultivation novels. The Goddess of Fierce Battles mentioned a magic academy, which may meet your requirements. In addition,"The Best Mortal in the Other World" and "Dragons and Magic at Hogwarts" also mentioned the School of Magic, but they belong to two different categories of modern magic and light fiction-derivative fanfiction, respectively. They may not completely meet the type of magic novels that you need. I hope my answer will be helpful to you. If you are interested in other types of novels, please continue to consult me. I hope you like this fairy's recommendation. Muah ~π
