Kinetic energy... a simple term yet carries unlimited potential.
After learning the usefulness of kinetic energy in battle, it opened a new world for Leon and lead him back to one profound truth; only speed is unbreakable.
Speed could be converted into raw power and that power could be transferred into his attacks. As long as his body was strong enough to cope with the transference, his spear throwing attacks could reach unimaginable heights, slaying opponents beyond his level with one shot.
"I'm going to become a one-shot wonder." Leon smiled, as he inspected the condition of his arm by contracting and relaxing his muscles. "It's seems my body has become a bit stronger after reaching the 9th Layer of Body Tempering Realm. I can withstand threefold with little damage incurred. Once I reach the peak 9th Layer, I should be able to use threefold strength freely without a problem."
