After criticizing a novel, Qi Hongdou transmigrates into the book and becomes Zhang Daihe, the notoriously difficult old matriarch of the Zhao family in the 1960s. She also activates a Family Reformation System and must accumulate 100 merit points to return to her original world and gain an additional 50 years of life. To change the original story's ending, in which the entire Zhao family suffers retribution, she stops her sixth son and his wife from splitting off from the family, protects her mistreated granddaughter Zhao Yuxiu, disciplines her lazy youngest son, and helps her abused daughter get a divorce. She also leads the villagers in catching kidnappers and helps the production brigade establish a sugar-making business to increase its income. After overcoming countless troubles and finding her long-lost second brother, Zhao Yuxiu succeeds in entering university. Once Qi Hongdou earns enough points, she cannot bear to leave her family and requests permission to stay, while the system keeps the way back open.
