The War Goddess Widow Strikes

A female war god transmigrates into a rural village, becoming a substitute arranged marriage widowed daughter-in-law oppressed by the clan! Her in-laws are weak-willed, relatives greedy. She crushes schemes with her fists, reshapes the family, lifting the poor household out of destitution. She brings home a disabled sent-down youth, a hidden genius of electromechanical engineering. One excels at combat, the other at craft, they turn scrap parts into industrial miracles.
