In the Tianyuan Continent, the Way of Alchemy reigns supreme. The Luo family, a renowned alchemy clan, guards the mysterious "Illusory Moon Alchemy Canon." Luo Chen is a member of the family, but his inferior spiritual root leaves him cast aside. Then, in an abandoned library, he discovers the "Spirit Breath Art of Returning to Truth" and embarks on the path of alchemy.
He stands out in the family's alchemy competition, only to be slandered by Luo Feng and others and driven out. While wandering, he hears of an alchemy relic in the far north and resolutely sets out for it. Deep within the ruins, he inherits the legacy of an ancient Alchemy Sage. His alchemical mastery soars, and he becomes a true alchemist.
Meanwhile, the Luo family is plunged into crisis after offending the Spirit Firmament Pavilion, which demands the "Illusory Moon Alchemy Canon." Luo Chen returns in triumph and uses his skills to refine a divine pill and avert disaster. He exposes the misdeeds of Luo Feng and the others, becomes a hero to the Luo family, and is honored as the "Defiant Alchemy Sage," forging a stirring legend from a discarded son to an alchemical icon.
