"Your perception is truly astounding. I did my best to conceal myself, yet you found me in less than a heartbeat."
Cain simply shrugged.
"Unless you can hide from the Flow itself, it is impossible to hide from me."
As he spoke, Cain's crimson eyes focused on the Demon King, and a flash of surprise appeared on his face.
"You've grown stronger."
