'Output control. Input control, and flow stability... I guess it's not a bad idea separating energy control into those three topics.' Simon thought while resting his head on his fist.
He now had a little bit of interest in the class.
Meanwhile, Instructor Valdin paused for a few seconds as he stood before the class with his hands clasped behind his back.
His eyes moved slowly across the initiates gathered in the classroom.
"Before we begin the class on Output Control," he said calmly, "I want to ask you a simple question."
He paused, allowing the silence to stretch for a little while.
"What determines the strength of a demonic attack?"
Several students eager to get in the good books of Instructor Valdin, raised their hands immediately.
"Power," one of them said confidently.
"Demonic energy," another answered.
"A stronger Demon Heart. A higher heart rank," someone else added.
Instructor Valdin gave a small, unimpressed nod.
