Did it even need an explanation anymore? The strongest skill that Alan could use freely? It was the Glacial Meteor.
But even it, with the might it descended with, didn't faze the Minotaur king at all! He simply roared once more, in order to increase his own vigor.
[A mere rock!]
The Minotaur king readied his blade, and his mana ran flowed within it, and his muscles, enhancing his strength several-fold.
[Is nothing!]
He swung once, and a crescent slash was released from his blade that went unperturbed towards the meteor, and even beyond it. Towards Alan, who dodged it by flying to the right. The meteor offered no resistance to stop or even weaken the slash, it was cut in half.
Those halves began to fall away from their intended target...and the stone was ripped apart. He had only delivered one blow, but it was enough to not only cut it in half, but also blow the meteor apart afterward.
