In the 14th year of Yongning in the Great Qian Dynasty, Su Jinyao, a cold-hearted medical girl who controlled 72 medicine halls in the world, was sent back to the capital by her biological father Su Wenyuan in the name of "happy occasion" to marry her sister Su Jinxuan into the Chen family of the Duke of Anguo, who was about to be convicted.
On her wedding night, she discovers that the groom is not the frail young cousin Chen Zhao as rumored, but a mysterious man - Xiao Xuanyin, the Seventh Prince of Daqian - who uses the art of disguise to assume his identity, infiltrates the Chen family through marriage, and then escapes from the capital through an exile team.
The two "fake" tested each other in the bridal chamber without exposing each other, and reached an alliance.
That night, the imperial edict suddenly came down, and Anguo's family was confiscated and exiled, and the Su family was also convicted for being implicated.
Su Jinyao used the mustard space in the ancestral jade ring to move the two mansions of Anguo Gongfu and Su Mansion completely within two hours before the arrival of the Imperial Guards. The commander of the Imperial Guards looked at the empty mansions as if they were seeing ghosts.
On the way to exile, Su Jinyao used medicinal materials and dry food as bargaining chips to suppress the evil servants of the ladies in the exile team, turning the painful journey into her mobile shop. Xiao Xuanyin secretly gathered the scattered remnants of the old army, and the two moved forward side by side with the interest alliance of "she collects food and he collects weapons."
After arriving in the barbaric land of northern Xinjiang, Su Jinyao used the space to cultivate high-yield crops and built a border city with full granaries from scratch; Xiao Xuanyin recruited barbarian tribes, trained private soldiers, and gradually built an iron cavalry capable of defeating the capital.
In the process of jointly resisting foreign enemies and cutting off political enemies, the two went from "unconscious alliance" to "life and death side by side", and finally officially joined hands.
In the end, Xiao Xuanyin led his cavalry to Beijing to quell the chaos, and Su Jinyao used medical skills and food to determine the hearts of the people. The two joined forces to end the troubled times and create a new prosperous era.
