The Sharp Blade Won His Silent Heart

A law in the old kingdom says a woman who is unmarried at twenty goes to prison. Qu Wenxi, a weapons expert, wakes up in the body of a girl of that age who had been infatuated with a man who treated her badly. She drops him and starts looking for someone else to marry before the deadline. She settles on Zhao Xianye, heir of the Zhao household, who is good-looking and turns red in the face and ears at the smallest bit of teasing, and she decides he will do. The Zhao household is then in trouble, with a hundred thousand troops surrounding the city. War is what Qu Wenxi knows. She builds weapons for him and he wins battle after battle. Afterwards she coaxes him toward marriage and a houseful of children.
