I Was Expelled from the Magic School and Became a Security Guard.

A 22-year-old pig farm employee Yun You set two records with a magic school admission letter that was eleven years late - The oldest freshmen admitted, and the fastest expelled students. The principal said: If you are overage, you cannot enroll. Yun You said: I have the green onion artifact. MAGA: Yun You is right. So this social man who couldn't even spell and had zero magic power became the most absurd magical security guard in history. The job responsibility is to guard the back door, and the equipment is a green onion that can send the entire school's senior officials to the hospital. Yun You originally wanted to freely experience this belated magical world, but found that the special escape line was destroyed after use, the admission letter was eleven years late, and the dim stars in the void... All of this is a road paved by someone's hard work.
