There are countless uses for Spiritual Power, but at the very beginning of martial arts, the warriors only used it as a fuel to enhance strength.
Shielding muscles, bones, and fascia with Spiritual Power to unleash physical power, the most ancient warriors only had this one fighting method: fighting with brute force. A blow that could muster a hundred-thousand-catty of strength was deemed a qualified warrior.
Humans clashed with monster beasts in contests of strength, smashing their teeth and tearing their skins with overwhelming force. Warriors seldom lived past a hundred in those times. Even with the protection of Spiritual Power, their bodies would shatter in the hundreds of thousands of collisions. The hope of recovering from severe injuries was nothing more than wishful thinking.
