Jia Yuqin was still pregnant with Bai Shining's child.
How could Bai Shining let her marry someone else?
Therefore, Bai Wutong had ample reason to suspect that Bai Shining had deliberately killed the original Bai Wutong's mother.
However, when her mother was about to give birth, all the doctors had said that the position of the baby was very correct and there was a high chance that there would be no problem.
However, she had died of blood loss during birth.
Not long after her mother died, the midwife in charge of delivering the child disappeared without a trace. All the servants around her were also sold. A maidservant who was loyal to the original Bai Wutong ran back to her mother's house and cried that Madam had been killed. Her family came to demand an explanation, but was chased out by Bai Shining.
Later on, the original Bai Wutong's maternal family committed a crime and were all decapitated.
