Mugen Souri: jutsu training, Fire style

Mugen stands in a ring sourrounded by wooden training dummys, he closes his eyes and and waves his siigns: "fire style, fireball technique" he shouted and the fireball that he generated hit one of the dummys and it turned to ash. he then jumped and in mid air he again made signs and said: "Fire style, Blazing shuriken dance"  and the 4 blazing shuriken came from 4 different directions and hit 4 different dummies. " thats enough warm up" he mumbled to himself. " now for the challange"  he now tragetet three different dummies that was scattered in different places, " fire style. Phoenix flower jutsu!" this was the new jutsu he wanted to try, he did the hand signs right but there were only smoke that came. he tried it again, but the same things happened. and again and again. for over 30 minutes he tried. he sighed and wanted to give up but he knew that he couldn't to that so noe he sat down with his feet crossed. concentrated on his chakra flowing through his body. he sat there for a few minutes and then he opened his eyes. He stood up and tried it again. "Fire style, phoenix flower jutsu!". the flames came bursting out in all directions they were not that big as he expected at first. he continued for several hours and finally he got it right, almost perfect.
