Modern girl Qi Hongdou accidentally time-travels into a book as a sixty-year-old Zhao family matriarch and activates a closed-beta modification system, where every day she lives can trade back for real-world lifespan. The family's sixth son and his wife stir up a family split, angering the original body until she falls ill. Faced with a whole family of children and daughters-in-law harboring their own agendas, Qi Hongdou no longer endures, making decisions in public, agreeing to split the family for the sixth son's couple, and starting a life of reforming a distressing family.
