Li Lianhua awakens in the body of a legendary yet dying swordsman, the former Sword God Li Xiangyi, now reduced to running a humble mobile clinic known as the Lotus House. Plagued by the lethal Bicha Poison that burns his life force with every use of power, his future seems bleak until a mysterious system activates. By treating patients and collecting medical fees, he can unlock treasure chests containing divine skills, rare items, and heavenly treasures.

His first major reward is the Dual-Complete Hand, a miraculous ability to reshape flesh and cure any ailment. Just as he begins to stabilize his condition, he encounters Ding Dian and Di Yun, fugitives hunted by imperial soldiers for a secret treasure. Recognizing their value not just as righteous heroes but as potential sources of future wealth, Li Lianhua decides to intervene.

Displaying hidden Pre-Heaven sword qi, he draws a line in the sand, declaring that no one, not even death, can take his patients away. Now, the seemingly frail doctor must balance his desire for a quiet life with the chaos of the Jianghu, all while farming rewards to fully reclaim his former glory.
