As for the black-robed man, Sunan couldn't quite figure him out.
Judging from his appearance, he is highly likely to be on the path of semi-shadow transformation.
Some wizards, in order to gain more powerful forces or prolong their lives, will choose to integrate shadow power into their bodies, completely transforming their physical forms into shadows, thus acquiring the ability to control shadow power.
Of course, wizard apprentices definitely cannot achieve full shadow transformation, but semi-shadow transformation is possible.
Moreover, those black tendrils manipulated by the black-robed man are somewhat like shadow tendrils.
It's also possible that he has actually fused with the bloodline of some peculiar shadow creature.
In any case, the power currently displayed by the black-robed and gray-robed man has reached the Tier Three Legend level, ranking among the upper middle echelons of Level 3 wizard apprentices.
