Bab 633: Trouble

"This basic level of Explosive Fist Arts only offered increased defense, but the intermediate level should offer the vibration effect. I have to carefully test it."

He didn't stop and went directly to the test rooms at the back of the field. He looked around and picked one without anyone inside. He carefully locked it from the inside just to be sure no one would be looking.

He walked up to the wooden weapon rack and picked up a curved knife.

Thud!

He stabbed the knife into his left arm. It didn't pierce through the skin, stopping at the surface as if it had hit a very hard wooden surface.

David slowly applied more and more force onto the knife. The strength applied to the knife instantly went over 10 % of his strength, then slowly 20, 30, 40, 70…

Psiii!

After a slight noise, the tip of the knife went through his skin, and David immediately stopped applying the force. He looked at the point on his skin that the knife had pierced.
