After Lu Xinyi discovered that he was a book wearer, he acquired a "script correction" ability. She can see the key plot points of the world (or the book), and has an extremely precious opportunity to "repent" - at the moment when a certain plot is triggered, she can consume mental power and return to the state 24 hours ago. This ability is not invincible. There is only one chance to look back at each key plot point, and every time she uses it, she will forget a memory about the real world. She used this ability to tear up the fate of the "cannon fodder female supporting role" in the process of self-redemption, while competing on the balance of espionage and love, and finally revealed a darker mastermind than in the book.
