Su Fan grew up atop Shennong Peak, learning the Shennong lineage’s Yin-Yang Medical Canon and the mysterious Secret Scroll of the Yellow Springs. He earned the title of “King of Hell,” but his life hangs by a thread because of his Nine Yang Severed Meridians. His master tells him that the only way to prolong his life is to marry a daughter of the Yang family. Carrying a marriage contract and red pine mushrooms, Su Fan steps into the bustling city.
At the Yang family’s home, his fiancée, Yang Zixin, humiliates him in public and tears up their engagement. At the crucial moment, Yang Susu, who is disabled but resolute, takes the initiative and marries Su Fan to repay his kindness and defend her dignity. After the wedding, Su Fan, seemingly just a poor country boy, repeatedly reveals his extraordinary abilities while treating illnesses and dealing with underworld conflicts. Yang Susu’s attitude toward him gradually changes, and their feelings quietly grow warmer.
However, Yang Zixin and the forces behind her harbor hostility toward him, while others covet his abilities. When word that “King of Hell has descended into the mortal world” spreads across the land, the Third Princess and the Kunlun Saintess come looking for him as well. Caught in the whirlpool of the city and the martial world, how will Su Fan write his own legend?
