Su Xiao was bound by something that called itself the "plot repair system". Her mission is to travel into various collapsed novel worlds, repair plots that have deviated from the main line, and get the story back on track. But something goes wrong in every mission - the male protagonist turns dark in advance, the female protagonist suddenly awakens, and the villains go on strike collectively. What's even more troublesome is that the same mysterious man will appear in every world, smiling and saying to her: "We meet again, destroyer."
