I would draw my bag of secondary weaponry to my front, drawing several Kunai from it and holding them firm in my grasp, I continued to close my eyes and focus forward my Katon Chakra into my lungs, upon a fair amount of gathered Chakra, I would raise my arm to the side and hurl the several Kunai forward in a volley and arch of weaponry.
I then quickly drew forth the Katon Chakra I had gathered and insisted it into my mouth, and upon gathered Chakra and proper timing, I released the Chakra from my mouth in the sense of flames, and with such the flames shot forward and consumed to Kunai, catching fire to them.
I had aimed the volley of weaponry to head toward several trees ahead, and upon impact to the trees, they would stick to the trees. With the intensity and thickness of the Chakra, thus making the flames un-extinguishable, the flames slowly trailed their way down the Kunai blades and onto the handles, where which paper bombs were secretly and strategically placed upon the bottom of the handles, out of sight, out of mind... Once the flames reached the handles, they caught fire to the bombs, in which resulted into large bursts of explosions and flames, mixed with a debris of wood shards and planks erupting outward from the explosions.
