Chapter 685: Two Heavyweight Allies.
[Oh....? Despite looking so big, he's not an Ancient Dragon but an adolescent one.] Roxanne spoke.
And that got Victor's attention. He looked at the big Dragon, who he couldn't see as just a 'teenager'.
[Are you serious?] Victor couldn't help but question.
[Yeah, look with your Powers. You'll see that his Soul isn't mature enough.]
Doing what Roxanne said, Victor's vision changed, and he could clearly see that the Dragon's Soul was not mature enough to be considered an adult.
The proof of this was that when a Soul reached the 'mature' age, the Soul became more 'solid' and 'brilliant'. At least, that was the case with Supernatural Creatures that lived a long existence.
A detail that Victor learned from 'testing' and training in Hell for all those years.
