Xue Jing experimented with interest in the Army Master's ability to enhance weapons.
Due to True Martial, he was now able to channel energy throughout his body, even using his eyes, the least likely places, as 'weapons.'
Therefore, in his understanding, his entire body qualified as a weapon, and Army Master's enhancement could be applied throughout.
This resulted in him even being able to cover his entire body in platinum color, transforming into a veritable body of steel, an indestructible body...
However, as he tried further, he also discovered issues.
This platinum-colored enhancement was not permanent and seemed to have a 'quantity' limit; the larger the area covered, the thinner the distribution, and the weaker the enhancement effect.
When used on the body, the best method was still to concentrate on the fists and feet and instantaneously focus on the area being attacked when an opponent attacked for defense.
