Blazren and Zain entered a hidden room deep inside the Hero Association building.
The hallway leading to it was dim and empty.
The walls were reinforced with thick metal, and the door they passed through had multiple locks and security checks.
Inside, the room was quiet, with only a few lights and some combat training dummies standing in the corner.
Blazren walked to the center and crossed his arms.
"Before we go further," he said, "let me tell you something important."
Zain leaned against the wall, watching him carefully.
Blazren continued, "Class… It's not am ability."
Zain tilted his head. "Then what is it?"
Blazren looked at him.
"You could say it's like a high-tier ability... Or at least something like that.
"A deeper system. Something rare."
Zain frowned. "So it's not just a title?"
Blazren shook his head.
"No. And here's the key."
"Having a Class is also one of the requirements to become S-Rank."
