Academy for People with Limited Ability

This is a world of espers, and one percent of people in the world are espers. Each esper has a "powerful" ability, but because the world is fair, espers have abilities but also have limitations, and limitations cannot be eliminated. I, Bai Yaohui, have the ability to overpower all things, but at the same time, I also have the strongest limitations. My ability can turn back time. , And the restriction is that I need the pain level to reach level 3 or above before I can activate it. The higher the pain level, the stronger the time backflow, and the most annoying thing is that after I go back in time, I don't have the memory before I go back in time. The only advantage is that I can freely control the time back. In this way, I took the strongest and least ability, and had a wonderful adventure in the monster gathering place of the esper academy.
