Just now, Shi Feng had felt the energy attribute of the Sacred Flame, which coincided perfectly with the Nine Nether Technique he cultivated, both being of Yin nature. This also happened to provoke a bold speculation from Shi Feng's past life, the fusion of Heavenly Fire with Dantian, merging into one, making Heavenly Fire the source of Martial Arts Power.
Of course, this was merely an idea conceived by Emperor Nine Nether in the past and was never put into practice. On the whole Tianheng Continent, probably only Emperor Nine Nether, that madman, dared to have such an idea, and even now dared to attempt it.
For a Martial Artist, the Dantian is crucial; once it is destroyed, all Martial Arts Cultivation is wasted, leading to a life of disability, unable to cultivate ever again, life severed from martial arts. Even more severe, if the Dantian explodes, one dies and the martial path fades.
