The other voice’s words

  Just like the last time, Harry also sensed the energy within him flowing once more, except this time, it was flowing through his legs, boosting his speed.

   One thing he noticed was that the amount of energy that was being utilized by the system to activate [Accelerate] was a lot more than the one needed to activate [Rock Fists]. 

   However, this didn't surprise him. After all, the skill level of the former was a lot higher than that of the latter.

   Harnessing his energy, Harry directly increased the amount of energy flowing through his legs.

     And unsurprisingly, he could feel his speed and agility increasing even more, rising to levels he never thought was possible before today.

   Although no notification about more stat points being added to his agility appeared in front of him, Harry could feel that his agility had already increased even more than before.
