Super Seminary: I Have a System

The sudden system brought Sumo to Super Seminary. But what makes him depressed is... Why do other people travel through time with all kinds of awesome people, but I only have a useless system when I travel through time. To put it simply, this is the story of a diaosi who got the system and traveled to a super seminary. She is not invincible, does not have a harem, and does not want to enter if she does not like it.
