The [Annihilation Sword] technique that Vexthra gave to Kent has seven forms. So far, Kent had only mastered the first two forms, or more like he had only learned the first two forms.
He was too busy to focus on the other forms, and since he wasn't always in danger, which required him to go above and beyond, he never bothered to learn.
The first two were enough for him.
[Rapid Slash] is the first form. It allows him to unleash 450 sword arcs with a single swing of his sword. He had already mastered this to perfection, allowing him to unleash all 450 sword arcs.
Although it is a powerful sword skill, it is most useful in large-scale battles. Since not all 450 sword arcs would land on the target, using it against multiple targets is more useful.
Then there is the [Void Cleave] form. This skill is as simple as unleashing a single sword arc, but the longer it moves, the stronger it gets.
The same sword arc will do more damage to a person standing 30km away than 3km.
