I begin by sending chakra into your brain and then blinking. As soon as I blink I place you under a illusion where the image you are seeing/looking at begins rippling to the point where you have no clear understanding of whats going on and you are confused by whats going on.
(Genjutsu:Igameru Mokushi) Illusionary Technique: Distorted Sight
I then right afterwards send my chakra under you and switch to katon, and causing a large fireball to rise underneath you. I constantly send chakra into the fireball until it completely surrounds 5m radius around you which is done very quickly. I add chakra into it, making it hotter and by then you should be completely incinerated.
A single hand-seal later and all the fire under you which is being compressed, restricting your movements and preventing you from forming hand-seals. A single hand-seal later and the fireball explodes and obliterates you.

I then use a jutsu which makes my sand thrice as fast, however you would have no idea about this.
