Yun Weiyang, the most unpopular seventh princess of the Dayu Dynasty, was married as a substitute to Xiao Jue, the third prince of the enemy's Beixuan Dynasty, who was famous for his playfulness. On her wedding night, she was humiliated, misunderstood as a pawn and a spy, and abandoned like a pair of worn shoes. At the lowest point in her life, she unexpectedly awakened the [Miracle Medical System]. Relying on medical skills that surpassed the times and peerless martial arts that she quietly practiced, she maneuvered between the rivers, lakes and courts - from treating the plague people to cracking the palace's strange poison, from Shaolin Taoism to Wudang secret realm treasure hunting, from forming an alliance with the chief helmsman of the Beggar Clan to fighting to become a god in a martial arts conference. She used medicine to enter martial arts and used martial arts to prove Taoism. While uncovering the mystery of her mother's death, she was involved in the vortex of Beixuan's imperial power change and the catastrophe of the world. Xiao Jue, who once despised her, saw her saving people in the midst of thousands of troops and being surrounded and killed by thousands of people without being defeated. He was shocked to realize that this woman was no longer an abandoned concubine at the mercy of others, but a "sword and doctor" who controlled life and death and shocked the world. The road to chasing a wife begins with awe and ends with insanity.
