Fire Release: Flaming Ocean Burial

Releasing Fire so hot that it literally turns Earth into gas, Shikizaki unleashes a massive ocean of flames using the massive amounts of chakra flowing through his body. These flames obliterate literally almost any defense constructed by the enemy, and turns the place where his flames were released into a place that is practically impossible to survive in, as the ambient temperature rises to a bare minimum several hundred degrees Celsius, utterly incinerating anything in the vicinity. This is disregarding the gaseous state of solid rock and metal which are on the ground level.

If concentrated and not spread out, it can easily create a hole several hundred meters deep.
