Modern office worker Xie Yuan transmigrates into a book as a cannon-fodder concubine-born daughter of the Marquis Yongning’s household. To save her life, she activates a laid-back healing System, refuses to get caught up in cutthroat competition and household infighting, and earns rewards by slacking off and helping the household’s residents heal. She meets the Seventh Prince Huang Shouqiang, who seems carefree but secretly wields real power. The two help each other heal, and their feelings gradually grow. Xie Yuan thwarts the Marquis household’s schemes and purifies the resentment in the imperial harem. In the end, she rises from a concubine-born daughter to a first-rank titled lady, and joins Huang Shouqiang in building a life as an emperor and empress free from cutthroat competition.
