Why Are All My Disciples Young People in the Second Grade of Middle School?

As a time traveler, my mission is to be a teacher for others. I want to dominate this other world, okay? The system disagreed, so I tolerated it. But why did you ask me to be a teacher? I didn't graduate from university. I also endured it. But can you give me some normal apprentices? I ask you if you want to dominate the world, but you are not interested. Asking what kind of women you like, you like Qiqi, Sister Pao, and Athena. Why don't you die? My mentality is broken!
