Modern heroine Shi Yuanyuan crosses into a 1983 period novel, binding with a merit-based life-extension system, and must play a vicious female supporting role to accumulate lifespan. Little does she know the system has a bug, and all her inner thoughts can be heard by people in the Lu family, Shi family, and others. While deliberately acting proud and crazy to farm anger points and save her life, she casually drops spoilers, successively saving hardship-ridden figures like Lu Caimin and Su Tong, and exposing the conspiracies of human traffickers and her stepmother. Relying on superb medical skills, she becomes the disciple of national treasure Elder Gu, and hands over CT and vaccine blueprints in exchange for merit. Her fiancé Lu Yuan has long perceived the truth and guards her silently; she continuously reverses tragedies, weakens the original heroine's fortune, unmasks lurking spies, and finally breaks free from her cannon fodder fate.
