Lin Xiaoxiao, a modern medical genius, woke up after a laboratory explosion and found that she had traveled back in time to the period novel "The Great Courtyard" that she had just finished reading, and became the vicious female supporting character of the same name. Lin Xiaoxiao learned through the memory of her original body that she had been exposed as a fake daughter. Zhou Xiaolan, the real daughter, had just been taken back to the Zhou family, and she was facing the situation of being sent back to her biological parents' home in the countryside. At the train station, Lin Xiaoxiao met the four brothers who came to pick her up for the first time, and was touched by their simple concern, which was in sharp contrast to the "cannon fodder family" described in the book. Returning to the poor but warm Lin family, Lin Xiaoxiao secretly decided to change the fate of the family.
