Over the next few weeks he extensively practiced his concentration immensely. He spent well over most of the day simply trying to hold his new skill as long as possible. After he finally was able to control it well enough to use it in combat he began to practice his skill by cutting various foliage. Trees, rocks, small hills, whatever he thought he could cut with his new skill he tried and succeeded. After a week of practice he felt that it was finally time to name his Jutsu. He decided to name it Swirling Fire Fist because of the way the fire constantly twirled around his hands and swords. With his new Jutsu complete he went to find a use for it.
