Upon hearing the instruction from my sensei, I turn my head around to face the clones that make their way towards me, with presumably hostile intention. Spewing a thin jet of fire, the clones are all dispelled quickly upon being caught by the dangerous Katon technique. After that, I notice another group of clones running towards me. I take a deep breath of air, imbuing the air within my lungs with my chakra. Immediately after, I superheat the chakra within my mouth. I then spew the fire, but manipulate it so that when I spew it, it will slowly increase in width and height the further it gets from my mouth. The clones all run towards the massive wall of fire, and are subsequently dispelled.
The first technique is a simple jet that flies through the air. It is a technique built for attack, in contrast to the 2nd technique that I just performed. The 2nd technique is built for defense that is quite dangerous if used correctly.
