You Can't Steal My Daughter's Inheritance

Lu Yang, born into a poor family, married the city's delicate girl, Gao Minmin. After marriage, Minmin devoted herself to their small family, but Lu Yang favored his widowed sister-in-law and nephew, ignoring his wife who was seven months pregnant. This led to Minmin dying from delayed medical care during childbirth, leaving behind a sick daughter. Lu Yang's true colors of misogyny and greed were fully exposed; he abandoned his sick daughter, seized his late wife's property to marry a new wife. Unexpectedly, this was all a trap set by his mother-in-law, Shen Qing. She wanted Lu Yang's family to pay for their cold-bloodedness, seek justice for her accidentally deceased daughter, watch the heartless man meet his deserved end, and finally, raise her daughter's last bloodline alone.
