Chen Yu, a PhD in Chinese Pharmacology, unexpectedly travels to another world and becomes Chen Yu, the useless son of the Chen family, whose dantian is shattered and meridians completely destroyed. The world of immortal cultivation has already pronounced him beyond saving. Abandoning traditional alchemy, he instead draws on the principles of traditional Chinese medicine and herbal pharmacology, combining ordinary medicinal herbs to brew decoctions and painstakingly repair his meridians. Along the way, he faces oppression from the Qin family and doubts from his own clan, but unexpectedly discovers the secrets of the Fate-Reversing Pill left behind by his grandfather. Relying on his knowledge of herbal combinations and his ingenuity, he overcomes one crisis after another, develops a medicinal formula to repair his meridians, and gradually regains his cultivation. Finally, at the competition between the three clans, he uses the power of Chinese herbal medicine to turn the tables and take revenge, forging a unique path to immortality through herbal medicine.
