The heroine traveled to a heroine rebirth + system novel and became cannon fodder who could die at any time. She discovers that the biggest villain in the book, the yandere prince Ning Wang, will massacre the royal family due to madness in the future. The female protagonist chose not to side with the male protagonist or to help the male protagonist. Instead, she used modern neuromedical knowledge to treat Prince Ning's brain tumor before everyone else, turning it into her own "life-saving talisman." Every time Prince Ning fell ill, she openly went in and out of the palace to "see a doctor". Everyone in the capital knew that Prince Ning couldn't live without her, so naturally no one dared to touch her again. She is a troublemaker who takes care of herself, a plot saboteur, and an intrusive player who reduces the dimensionality of all members.
