Transmigrating into a dying furnace boy whose spirit flame vein has been drained dry by arrogant inner-sect elites, Gu Qingxuan inherited nothing but a cracked, leaking bronze cauldron. In this world, ancient clans and sacred dynasties monopolize underground spiritual flames, selling exorbitant Fire Jade to enslave rogue cultivators. Everyone believes only violent earth fires and fierce beast blood can forge immortal pills. Little do they know: True Yang is born from Extreme Yin. "Take the center of Water to ignite the hidden fire of Heaven." Without costly spirit coal or wild subterranean fire, Gu Qingxuan gathers morning dew from thatched eaves and the very first purple ray of the rising sun. Inside his broken tripod, he creates the peerless Pure Sun Primordial Flame with sheer artisan precision! While noble prodigies blow up cauldrons despite burning through mountains of spirit stones, Gu Qingxuan crafts flawless, divine-veined pills using mere wild firewood. While supreme elders slaughter each other for a spark of heavenly flame, a tiny, fluffy, pill-craving Three-Legged Golden Crow quietly pokes its golden head from his sleeve. When the Eternal Frost Catastrophe descends and all subterranean flames in the world freeze into dark ice— Gu Qingxuan steps out of his humble shack. The tiny sparrow in his sleeve spreads its blazing wings into nine soaring suns, burning through the icy void and illuminating the boundless cosmos!
