The noise that accompanied Khan's kick announced something that he had struggled to confirm on Nitis. His technique had felt different, smooth in ways that his previous executions couldn't achieve. His mana and body had moved without requiring thoughts or strategies, and the power expressed by the blow marked his arrival in the superior proficiency level.
It had taken Khan almost eight months of relentless training, constant struggles, traumatic experiences, and unshakable resolve to achieve what most soldiers would see as a turning point for their battle prowess. The Lightning-demon style had finally fused with his instincts and habits to make him reach the competent proficiency level and unlock a path that went beyond the correct execution of his techniques.
