Yu Zhaozhao, the junior sister of the Xuanxiao Sect, was born with a "spirit of misfortune". Anyone who comes close to her will be unlucky, but her senior brother Xie Linshuang cannot be overcome. She looks squeamish on the outside, but is actually a scheming drama queen. She relies on pretending to be good to become the favorite of the master group, but she doesn't know that Xie Linshuang has been practicing the ruthless way for three hundred years and has already been secretly collecting the ugly purse she gave her. When Yu Zhaozhao mistakenly took the Love Gu Pill and had to listen to his senior's love words every day to stay alive, the Flower of Gaoling was forced to switch to "The Complete Collection of Earthly Love Words", and the whole teacher gathered around to watch the death scene. However, as the interaction between the two deepens, Yu Zhaozhao discovers that the so-called "bad luck" is actually ancient auspiciousness, and the backlash of Xie Linshuang's change of fortune is coming... From "senior brother taking care of the baby" to "senior sister protecting the husband", in the sweetness of two-way development, a fate that spans three hundred years is gradually revealed.
