My grandmother killed my violent father to protect my mother and me, but I was nicknamed the "granddaughter of a murderer." After my death, I became a system, accumulated enough points to customize tasks, and traveled back to 1950 to bind my grandmother. At that time, after his grandfather Chen Jianguo became famous, he wanted to abandon his wife and daughter and marry a progressive young woman. He also asked his grandmother to continue to serve his paralyzed mother-in-law. I helped my grandma tear through my grandpa's hypocritical mask and seek justice. I took my mother to the capital to start a new life. I also used the power of the system to help the country avoid hardships, let the scumbag and his new love get the retribution they deserve, and completely rewrite the tragic fate of three generations of my grandparents.
