Adam was overwhelmed and shocked by the power that the Killing Move, that he had come up with on a whim, was able to unleash.
His desperation, drive and pent up rage and killing intent were all unleashed at once as he let go of all restraints that he had subconsciously been placing on his mind, body and Bloodlust Charactetristc.
At that moment, he completely embraced and unleashed all the power and emotions that he had been suppressing that whole battle and most of the time on Floor 10 by having the Hunter's mind activated completely at most times.
The spinning of the spear surpassed anything he had ever seen and it became a blur between his palms after gathering wind and momentum as it caused a small tornado within Adam's hands after he integrated the two concepts behind the Air Palm Strike Skill.
