Three years ago, during a family mountain-climbing activity, Shen family's eldest young master Shen Moyan accompanied his grandmother and adoptive sister Shen Weiwei. Unexpectedly, grandmother was pushed down the cliff from behind by someone, resulting in paralysis in both legs. Shen Weiwei slandered Shen Moyan for committing violence to seize family property, and his parents listened only to one side, sending their biological son to prison. In prison, when Shen Moyan suffered endless humiliation and was gravely ill and dying, he was saved by a mysterious old man who took him as a disciple and taught him the peerless medical arts of the Medicine King Sect. Three years later, after serving his sentence and being released, the solitary Shen Moyan returned with heaven-defying skills, vowing to investigate the truth and demand justice from Shen Weiwei, who framed him.
