Tie Dan was equally baffled, yet he continued as before, using the Sha Sword to pierce inside for quenching, refining the essence of this faceless corpse into a piece of broken copper and rotten iron, rust and residue.
The weight of the Sha Sword nearly doubled, and the amassed True Qi volume practically squared!
As soon as Tie Dan surfaced back to the ground, the Spiritual Breath Dao Qi from all directions converged like a whirlwind, swirling around him, even causing unusual phenomena in heaven and earth! As if some Great Demon were emerging! Storms gathered at the pinnacle! It seemed as though heavenly thunder could strike at any moment!
Indeed, after the sword quenched two faceless corpses, the amount of True Qi harnessed ascended to the Nascent Soul Level...
If Tie Dan were still cultivating the Nine Luminaries Sword Scripture, he could now prepare to upgrade and break through to sword infant. Yet now Tie Dan dared not rashly make the breakthrough.
