I'm startled, what the heck.
An Su's eyebrows rose slightly, somewhat surprised that the princess could guess his identity.
No wonder she had been sneaking looks for so long.
The body he now inhabited was indeed very different from Merlin's, first and foremost because the total amount of magical power couldn't match that of Merlin's original body, and secondly, the amount of magic An Su could wield was limited,
Moreover, although the body was created by Merlin, its core was still An Su's soul, and the aura that emanated was also different.
But being able to discern the difference still indicated that the princess's level of magic was terrifyingly high.
You should know, previously a full seven saints had failed to see through An Su's disguise, even thinking that An Su resembled Merlin more than Merlin himself, a level of deception only the current God of Law could possess.
