Because he was utilizing the sword while sprinting, Ai Hui had to maintain balance which meant he was unable to lean forward. His upper body remained still while his lower back was like an extremely elastic and tough spring. The sword in his hand had to adjust and follow the movement of his body’s rhythm and tempo.
This matter only concerned the center of gravity; what was more difficult was the issue of breathing.
Controlling his respiration was much more difficult when sprinting as opposed to standing still. As an old hand at this, Ai Hui knew very well that if the operation of elemental energy was the essence of an elemental energy attack, then breathing was the foundation of any attack.
This included the most basic rapier. Strict breathing control was a requirement, and if the breaths did not synchronize with the swordplay, then not only would the power be lacking but injuries would also ensue.
