Marriage in the Seventies: After a Flash Marriage to a Rugged Soldier, She Builds a Cutting-Edge Defense Weapon

Mi Yingying, a working scientist from the 21st century, traveled back from a thriving new era to the struggling 1970s, and things didn't go well from the start. She became a domineering, unreasonable, cowardly yet arrogant woman with a terrible reputation and a hopeless obsession with romance. Her trash of an ex ate her food, used her things, and emotionally manipulated her. Since that was the case, she'd kick the scumbag to the curb and marry a soldier with broad shoulders, a slim waist, and an eight-pack. She would also return to her true calling, advance the nation's defense technology research, and live a happy life. At first, Ming Luyuan thought his little wife was interesting. Later, he realized she was an absolute treasure.
