Versatile Mage: a Hundred Years of Skill at the Beginning

Start with a light element, poor talent, don't panic, don't panic at all. A hundred years of skill, in reality, can only be practiced for five hours a day and controlled for one hour. In the simulation time, 24 hours a day is equivalent to practicing for one day, which is almost equal to practicing for 5 days. You can break it easily at mid-level, no problem at high-level, and you can challenge it at super-level.
