Kretos turned back into his Ren form, he did this because it was more important to feel the difference of mana and Spirit Aura using the actual body he was in. Chowan nodded his head in approval as he saw Ren in deep concentration. Leo who was watching at the side went closer to Chowan and spoke to him.
"How long do you think before he learns the basics of Spirit Aura?" Leo looked at Ren who was in a state of enlightenment and asked Chowan his question. He was confused as to how long other people get to learn something like Spirit Aura, since he himself learned it almost instantly.
"Well it's as expected of one of our incarnations, he is a true genius. Based on the rate he is going, it would take him around a week to fully comprehend Spirit Aura. Any normal person would have needed at least a year to comprehend the basics. If I had a student like this back when I was alive, I would've gotten to the end much easier." Chowan answered Leo with a hint of nostalgia on his face.
