I Transmigrated Into a Book as a Wicked Mother-in-Law, and With a System I Turned Things Around in a Famine

Overworked office worker Gu Wan wakes up in the famine years, reborn as the vicious mother-in-law everyone despises. With the family fortune spent and the whole household out of food, she's lucky to have a Family-Raising System to help her! She abandons her old favoritism, stockpiles food and finds ways to make ends meet, protects her children and grandchildren, and turns her life around in adversity to start anew.
