Fusion of Aura and Mana

Eldrin witnessed everything first hand with a stupefied expression appearing on his face.

"Please take care of them, old man."

Regis, who had appeared beside the old mage in the blink of an eye, spoke as he laid down Pandora, Killian, Larkson, and the unconscious Aurelia on the ground.

"S-Sure…" Eldrin stuttered, 'I didn't see anything.'

Even though he was exhausted, his senses as a master rank magician with years of experience could not be taken away from him.

However, he was not able to sense anything.

'There's not a single mana fluctuation. So it must be an aura art… But what kind of aura art is this powerful…'

Eldrin knew that, unlike magic spells with a stable hierarchy of power, aura arts were not the same.

His eyes remained glued to the boy's actions as he fed health potions to the others.

"B-Boss… i-is that you?" Killian coughed blood as he asked.
