The limit of every kind of magic was different from one another. A lot of spells were not upgradable. Only magic that could have been upgraded to perfection could be called true power.
The attacks from above had stopped. Six whole hours passed. The grade-9 sorcerer kept on bombarding with wave after wave of grade-9 spells, and had rendered all but the magic towers within the palace to smoldering ruins.
The result was not due to a lack of people trying to stop the sorcerer. All heavy alchemy arrows fired from the metal battlements on the palace walls were effortlessly repelled by the sorcerer. He then began to bombard the walls himself, until there were hardly any walls left standing of the palace of Daliang.
Nicholas attempted to get close to the sorcerer, but all his efforts with divine curses were easily dispelled by the sorcerer, scaring him enough to turn around and run instead.
