The Transcendent Mind/Fūjin

Fujin
Fujin, is a branch of The Transcendent Mind, practiced by those have masterd the usage of one of its technique, Tsumetai a technique that allows users to cool off their bodies to very low temperatures while recieving no damage.

To use this style one must achieve enough strength to produce fire through friction alone, this can be easier with the usage of Tsumetai as the body will be in a hardened state, using the enhanced strength along with their own natural strength practitioners would produce fire using friction, the high temperature of the fire combined with the cold body of a Tsumetai user would cause a temperature flux that would result in producing exetremly strong gusts of wind that are used by practitioners in battle.

Because of the huge diffrence of temperatures between fire and a Tsumetai's cold body, the winds produced are exetremly strong and has the ability to shatter rocks and building on kinetic force alone, however it requires for users to be exetremly skilled with Tsumetai so as to lower the temperatureof the body back right after producing the fire.
