Forcefully distorting his mental strength to use a Levitation Spell was in itself going against the laws of magic, and even though Lin Li had incredibly strong mental strength, he could not keep it up for long. It was just like how a mouse could never bear the offspring of an elephant, and even if it did, it would surely die during the birth. That was the situation Lin Li was in right now—he was flying very quickly indeed, but the mana was flowing uncontrollably within him. If he did not put a stop to this as soon as possible, he would surely suffer great injuries.
Unfortunately, he did not have the time to attempt to control it, as he had used up all his mental strength by forcefully propelling it to a level-20 Levitation Spell. There was no way he could control the impending bite of mana unless he stopped right now.
