The first to react to Adam's voice were not the Monte Carlo apprentices but Elliot and the devil. Without a moment's hesitation they flung themselves backward, and they did not stop until they were far beyond the range of the dueling platform.
Adam never wasted extra words before a fight—or rather, before a killing. From all they knew of him, they had never heard Adam show such naked anger and killing intent toward anyone, and it was easy to predict what would come next: if the Monte Carlo people didn't know their place, they would face Adam's devastating strike.
As for whether he could win? These were only apprentice-level opponents. They had never once doubted Adam's fighting power.
