Chapter 795: The Profound Meaning of Lightning (Part 1)

It was not difficult to advance the Fire Rain spell to grade-9, but to enhance its damage was not that simple. Fire elements were usually extremely difficult to control. The area of effect of the Fire Rain spell was huge and no mage would be willing to waste time on it.

Each fireball in the sky measured about a yard in diameter and they did not seem too powerful individually. They had been extremely accurate in hitting the magic towers however.

The defense of magic towers were undoubtedly powerful, such that even grade-9 spells were ineffective against them. These magic towers also needed to maintain the defense of the city. Under such overwhelming attacks, they would not be able to defend themselves and the city at the same time.

When the grade-9 sorcerer in the sky noticed that the anti-flying zone was no longer in effect, he did not descend. He instead began to chant a mantra once again.
