Will Strengthening My Body Make Me a Supreme Mage?

As a magician's apprentice, I have been practicing here for eight years. But at this moment, I can't help but wonder. What does it mean that long-distance running and weightlifting are not a required course for mages? What do you mean my master is not a mage at all? What does it mean that I am the first person to establish a sect? What does it mean that a staff cannot be used to cut people?
