Her parents were tenant farmers, her younger brother could not afford to attend school, and her younger sister had no winter clothes, so the family could only spend all day huddled under the covers. They were so poor that not a single person in the family owned a padded coat. With her exceptional skills, this modern, all-around female scientist with a doctorate leads her family to wealth and invents new technologies, transforming into the richest woman in the country! Her parents no longer have to make a living as tenant farmers. They own a thousand acres of fertile land and build the Xie family estate. Her younger siblings grow into pillars of society, and together they establish a new generation of aristocratic clan. And that is not all. When chaos descends, she builds war chariots and revolutionizes weapons and siege machinery. From a simple farmer's daughter, she rises to become the empire's female war hero! She casts aside her floral hairpins, dons silver armor, and makes princes and nobles bow at her feet!
