Luke chuckled and raised his head to think again. His right palm was still open and the air around it fluctuated as he tried to figure out if he had done anything wrong.
In less than ten seconds, he looked at the sandbag in front of him again. "Take this killer move — Bone! Transforming! Soft! Palm!"
His palm was gentler and less forceful than before.
But the moment it hit the sandbag, there was the sound of something tearing, and Luke's right palm pierced through the special material which covered the sandbag.
He drew his palm back and nodded in satisfaction. "With just a bit of practice, I can create an 'armor-breaking' effect with my palm. It's a little similar to Elementary Penetration, but the source of power is completely different. Interesting."
Elementary Penetration was a special mental class.
