"Sir, it’s indeed true that you haven't been hiding in the shadows, but is it a bit demeaning to disguise yourself as a disheveled prisoner?"
Michael had long guessed that a powerful figure from the Ji Yan Sect lurked in the underground palace, but he did not expect that this was the manner of their concealment.
If the other party hadn’t spoken out, even though he had spotted him, he never would have thought in that direction, assuming the individual was just another prisoner.
Although this person's aura was as depthless as an abyss, making it impossible for him ascertain its depth, the underground palace was home to a fair number of captives who had surpassed him in levels. It wasn't sufficient for him to presume abnormality.
However, if the man deliberately disguised himself in such a manner, he should've taken advantage of Michael’s momentary lack of awareness and launched a surprise attack instead of revealing his identity out of the blue.
