Although they are inside a room, there is nothing that can stop the Celestial Light from the Heavens falling on Aiden.
When Aeon's Life Skill upgraded to Transcendent, he received a Legendary Class and thus, he was both curious and expectant of what Aiden would receive from the Heavens.
'Swoosh'
The Celestial Light didn't last for long and disappeared after a couple of seconds as Aiden opened his eyes.
"Young Master, my Life Seed….it is upgraded to S-grade."
The moment he opened his eyes, Aiden directly informed Aeon about his [Heaven's Blessing]
"Life Seed Upgrade to S-grade?"
Aeon was pleasantly surprised because Aiden's current Life Seed was only a B grade but now, it has upgraded to S-grade.
'So, Heaven's Blessing changes from person to person.'
Aeon silently thought to himself as he congratulated Aiden for his blessing.
