Callan was surprised by Antonio's reaction, but he didn't dare to question his order and led the way towards the Palace Prison. There, they kept all the heinous criminals of the empire or those who had shown signs of rebelling against the imperial clan!
The palace prison was in the southern region of the imperial palace and was well guarded. Many powerful Imperial Guards guarded the passage, and the warden was also an imperial guard who ranked fifth in the imperial guard rankings.
When those guards saw the Mortal Emperor had come personally, they were shocked before they quickly kneeled in reverence.
Antonio merely nodded with a nonchalant attitude and paid them little mind. With Callan memories, he now had enough memories to make Antonio's profile, so it was very hard to find flaws in his disguise.
