Feeling curious was natural after everything that the rookie Death Wraith witnessed and heard, but he also knew that it was not his place to think about or pry into such things as he responded with, "Yes sir," before returning to the underworld.
That left Adam, who had blitzed far away from the Death Wraith, then awaited its return to the underworld before returning to his Physical Form in which he went back to the remainder of the Black Dragon Gang.
It had lost its boss and one of its 4 Powerhouses, while the entire gang had been defeated and unable to face against a single man, and yet there was still order and they all stood around quietly, waiting for Adam's next instruction.
He had suddenly disappeared from before them after watching Huang Feng and Bai Niu kill each other, and now reappeared as if nothing had happened and all they felt was a gust of wind that followed his rapid speed.
