Roan didn't discard that possibility. "True. However, it's more likely that he has a bloodline from a race with good sensory abilities. Obviously, it has something to do with his eyes as well."

Rean patted the boy's head before asking, "How old are you, little man?"

"I-I don't know," the boy answered truthfully. 

Rean didn't mind and touched his shoulder before sending his Divine Sense and Light Element inside.

Then again, even I can't give the precise day of his birth as there are small changes during one's growth. Well, let's just say you're six years and two months old for the sake of the matter."

Roan then mentioned, "I thought he was older than that."

Rean understood why. "Indeed. He does look older than he really is. But that's probably because of how dirty he is. Look at him. He's fully covered in sand rags."
