His speed slowed down, but his strength increased a little to compensate for the slowness of the movement.
The slowness was done so that he could have more control of his body movements, so his movements changed slightly.
Every so often, he would create a new movement. A new punch or a new kick, which was in accordance with the movement of the cursed energy in his body.
This energy was continuously moving in circles, so when he struck it with the sound of its movement, it shuddered slightly.
'Good...' He thought.
He continued to do the same thing for the next hour, but there was no change other than a small shudder. But when he tried to mold it at those specific times, it seemed a little less heavy, so he felt he was on the right track.
So, 2 hours later, he stopped.
"Jasmine." He said suddenly.
Jasmine was startled by his call, so she stood up a little. "What's wrong? We still have an hour of training left."
