Gabriel walked into the training grounds. He had a idea for a jutsu he was going to make a wind and fire ball. He had wrote down many thing for it he had a base idea which he was about to preform. He started to preform it again and again the jutsus each time gaining skill in it each time. If he keep doing it he would master it so he did and did and did. But there was a problem it never got better he tried and tried it still wasnt affective enough so he tried a different way to do it. The first time he tried to use a large chakra amount while keeping most of it in the fire then when it hits blow the chakra out and in. This time he would evenly balance it out and then have it exploded downward at the ground with the fire. With the air he would make it blow all around. This also failed so he decide to mix it up by shooting it the same way he did it last time but with a lot more chakra. He then made more hand signs when it hit the ground. This time it blew up around 5 feet the first time it was only 2 feet second time same. He then decide to make it smaller about the same size as of his fist he did so and he then put even more chakra in it 2 times as much. This time time without hand signs when it hit. He did so it made a 10 feet explosion this time. This time he double the chakra so the explosion doubled again. He was happy with a 20 feet explosion so he was okay with that. Now he was going to attempt to make multiple of them each with the same explosion of 20 feet. He did this it failed the explosions were tiny he tried again and again. He then tried it again and again. Finally he got it. It worked he wanted to be able shoot at least 20 he got 5 the first time. So he first tried to shoot it faster which he did same explosion so now he was going to increases it to 10 it worked to also so did 15. But 20 had worked to. Now he wanted to add the details which was easy he was going to make it more controllable so it could turn into jutsu so he did this he worked on it a few times he wasn't getting the right results that he wanted so he add in making hand signs to make it work better. He did so it exploded then he made a few hand signs then large fire dragon appeared it was a normal size dragon but he was happy with it he then tried to combo it he did so it worked well he had done a good job. The last thing he want to be able to do was to make them make a huge explosion or make one huge fireball/wind ball he did this it explode it was massive over 40 feet he then made a couple tries at making 2 which worked he then added jutsus to those they were much bigger he was happy with what he had done. He had got his results that he wanted and he then left the training grounds happy with his results.
