Death And Heavenly Lightning
Davis's figure flashed in the airspace of the Vital Tempering Sect Territory, appearing between the squirming crevices of the two grayish dragons.
He had killed more than a thousand Vacuous Beasts already, stopping the count because he was tired of it, not to mention his essence energy dropped to twenty percent while his soul force was hovering between forty to fifty percent, thanks to Fallen Heaven's refining speed.
