This way of easily destroying the world was very easy to achieve. It only required a level 1 spell with two specialties. A level 2 spell slot was enough for a Supreme magic Empress.
In other words, as long as it was customized, a level 3 mage could deal 3 points of cold damage to all creatures within a radius of 500 kilometers.
That was why when Zhao Xu read these words hidden in ancient times in the Floating Library of legends, he felt a little emotional.
It was no wonder that these two specialties from the frostflame land had disappeared in the long river of history.
Learning this kind of thing was the same as a child holding a thousand taels of gold in a busy city, seeking death.
He even suspected that everyone who had learned these two specialties was on the list of the goddess of magic and was being watched vigilantly.
