Dimension Invasion: Undercover Hogwarts

Chen Xing wore it inexplicably, but someone took the initiative to pull him over. Paranormal Administration Council: The world has been hit by a reality-bending event, and we need your help. To prevent the world from being destroyed! To protect world peace! He began his undercover career at Hogwarts. Miraculous contained objects, incomprehensible anomalies, and the inside story of the magical world. What awaits him is a bizarre world. --------------- Richard: Principal, if I tell you, the history of the wizarding world was actually born suddenly on a certain day in 80 years. What do you think? Dumbledore: Interesting idea. If true, it must be incredible magic. Richard: Magic, thaumaturgy, anomalies, no one knows why this happens, so I came to Hogwarts as an undercover agent. Richard: Three years later, three years later, seven years, principal! Do you know how I spent these seven years? ---------- Set as the world of Harry Potter invading a parallel world. Newbie, new book, if the deconstruction is not to your liking, or if you think the setting is unreasonable, please feel free to comment.
