This book must have a good setting! The heroine traveled through the HP world cycle and bound the "decent life extension" KPI many times. The fifth-year Department of Mysteries blocked Avada's Kedavra for Sirius, and fell into the rift in the time and space of the curtain. When she woke up again, it was not the castle of Hogwarts, but the magic hall of Moe Academy! The magic of dual worlds collides, and the heroine has magic damage + physical damage. (Disadvantages: It's not finished yet. It's a new author. There may be some OOC in the plot)
