'Shit! I need to run away from here! Why is this hateful guy who was the cause of my stress in this place? Looking at the aura lingering on his body, he seemed to have gotten stronger even though it's not too apparent because I can't see through his strength-disguising technique.'
The black-cloaked vampire man could tell that Randy had gotten considerably stronger than before, but by how much he couldn't tell, since it appears that Randy had used some technique to mask his true strength, or at least that was what he thinks.
However, contrary to the black-cloaked vampire man's belief, Randy didn't use any technique this time even though he does have such concealing means.
The only reason why no one could tell his true strength at first glance was due to his Myriad Energy Devouring Physique's unique trait. This prevents the probing of others' inspection of his true strength due to the chaotic aura that he naturally emits.
