The Lawless Swordsman: I Subvert the Rules of the Magical World

Everyone practices magic by relying on the Law of Deviation. The eight laws in my body are balanced and I am treated as trash. After picking up a black forbidden book, I learned: The more powerful the spell, the more fatal the loopholes in the rules. Fireballs are flammable, and I can turn fire into ice; if gravity falls, I can turn it back and hurt people. The whole world obeys the law of heaven, but I alone go against the law and overthrow all the laws of the world!
