What was Adam doing?
Well, he simply put his palms to the ground, activating his Nexus, the capabilities of which he hadn't yet demonstrated.
Oddly enough, after his defeat at Damien's hands, Adam's mind was filled with knowledge of what his Elemental Root and Nexus were capable of, but... some things were still unknown to him.
His Power Gene - Desecrated Sword, still showed no signs of life, remaining a mystery to Adam.
Douglas, Dahla, and Damien watched Adam's actions, some were puzzled, and some had just a mild curiosity.
However, Silvana could clearly see that Adam was now looking a lot like one of his strongest opponents.
'Steel Knight...' Silvana muttered internally. Looking at Adam's stance, she saw Steel Knight, who was ready to cause a shaking comparable to an earthquake with the vibrations he could control.
