Hearing my sensei's instructions, I create the Rasengan again. I begin to gather and mold raw chakra inside my chakra system which is then channeled into my right hand. I release a burst of chakra my palm. After expelling the chakra from my body I manipulate the raw chakra turning it into a small, dense blue sphere of concentrated chakra that is about the same size as my hand. Simultaneously, I begin to make the sphere rotate at extremely high speeds, generating a deadly amount of force and friction. I add some more chakra into the sphere to control it and maintain it's sphere shape. Remembering the balloon training, I know that I need to use great chakra control to make sure that the technique stays under my control and the chakra keeps it's form, completing the Rasengan. However, this time, I add nature transformation. Using what I have learnt from my Futon training, i start to knead a large wind chakra inside of my body which is then focused into my hand. After doing this, the chakra is released into the Rasengan, becoming infused with it. Using shape transformation and incredible chakra control, I coat the Rasengan in wind chakra to increase it's destructive power several times over. My new creation looks fairly similar to the original Rasengan, except it has four small blade-like protrusions of wind that extend from it, rotating around the Rasengan like a shuriken. This new Rasengan infused with wind chakra has incredible destructive force capable of inflicting great damage upon impact. Again, I test out the technique to see how powerful it is. Instead of using a tree, I run up to a large boulder and slam the Rasengan into it. The brute force of the Rasengan crushes the boulder and the sharp wind charka tears it apart and rips it to shreds. After this, I stop concentrating the chakra and the Rasengan vanishes from my hand.
