After Rebirth, I Became My Mother-In-Law's Child

In my previous life, my mother-in-law got pregnant with an illegitimate daughter behind my father-in-law's back. During the birth, my mother-in-law secretly exchanged the two children. After the child died of kidney failure, I learned the truth but was pushed down the stairs by my mother-in-law and died tragically. After I was reborn, I exposed my mother-in-law's pregnancy in advance. My mother-in-law was humiliated. When she wanted to repeat her old tricks, I secretly changed her back. In the end, the mother-in-law caused the tragic death of her daughter, and she was tortured to death by the angry father-in-law. Since then, my daughter and I have ushered in a new life.
