Flame Inferno, Annihilation

A Magical Beast could already be considered a high-grade one at seventh-grade.

Not only were they astonishingly intelligent, but they also possessed strong, domineering combat power.

It was very tough for a human to defeat a Magical Beast of the same grade, especially when their numbers increased to form a beast tide. Their level of destructiveness could be said to be terrifying at that point.

Everywhere they passed through, lands turned barren, and nothing would be left alive.

That was why the Fire Cloud Mercenaries were scared witless when facing a siege by so many Sixth- and Seventh-Grade Magical Beasts. If it weren't for the fact a "Saint Domain" was standing right next to them, they'd have fled for their lives a long time ago.
