After many battles, Joshua's Steel Strength assimilation rate was about to reach a hundred percent.
Aura is the power of combat, an extension of lifeforce, while the peak of lifeforce itself was 'Steel'. For Joshua who had derived Aura up to Steel Strength, his way of ascension was to go through toiling battles that destroyed and reshaped his body on every turn, with every victory rebuilding and sublimation of his body and spirit greatly elevate his Steel Strength assimilation rate. At hundred percent, Joshua would ascend to Legendary-intermediate, developing into an invincible Steel body, rising as an ultimate form that surpassed every natural species.
