Ye Xinyao was originally the eldest daughter of the Ye family. However, before her marriage, she fell into a trap set by her stepsister Ye Xinyue, resulting in the theft of the family heirloom 'Thousand-Mechanism Box' inherited from her mother. On the brink of death, she was saved by Master Kuyi, a reclusive medical immortal, who passed on his medical skills to her. Three years later, Ye Xinyao returned to the Ye family under a new identity. By exposing the conspiracy between Ye Xinyue and Nie Yunchuan and overcoming obstacles posed by people like Qian Lizhu, she gradually dismantled enemy forces ultimately reclaiming Thousand-Mechanism Box and taking control of the Ye family.
