Ye Shiqi would not underestimate the people of ancient times, they were incredibly clever in order to survive!
Since she changed her mother's destiny and consequently her own and her family's, the developments had diverged greatly from the content of the book she read.
In the book, she didn't meet the County Magistrate's daughter, nor did she meet Young Master Tang; she had no idea what Young Master Tang's life would be like later on.
She only knew that after her mother's death in the book, they got a stepmother and a stepfather, and the lives of the five sisters were quite miserable.
With no mother, they still had a brother because the stepmother gave birth to a son. They, the sisters, were treated like worthless animals.
Eldest sister still married this man, and Second Sister also married this Second Sister's husband, only the Third Sister's destiny was different. It seemed she married a traveling merchant and went to a far-off place.
