I Transmigrate into a Book and Bind to a System, Then the Soldier Falls in Love at First Sight

[Military marriage and raising children with the army + transmigrate into a book + space + punishing villains + love at first sight + age gap + everyday life and career] Handsome older military officer with a doting dad vibe VS pampered, feisty heiress A car accident sent Song Yu into a book. The good news was that her original self ate well, slept well, and dressed well. Practically perfect. The bad news was that her biological father was a scumbag, her stepmother was wicked, and her paternal grandmother despised her. Talk about bad luck. Only then did Song Yu realize she had become a mere tool in a melodramatic period novel, not even important enough to count as cannon fodder. Her only purpose was to give the heroine money and a golden finger. - Scumbag father and wicked stepmother, go eat peanuts. Cheap siblings, go join the countryside labor force. Vicious paternal grandmother, go back to your hometown. After dealing with all the trash, Song Yu was about to lie flat when her handsome military officer confessed to her. Looking at his handsome face, tall figure, and impressive assets, Song Yu thought: Should I say yes, say yes, or say yes? The families living in the military compound were stunned. The man was already well past the age for marriage and still hadn't taken a wife. Now he actually had one, and she was a gorgeous young woman so much younger than him. Everyone started gossiping. His comrades sneered: Shameless. He can't even take care of his family after marrying a spoiled heiress. The wives grumbled: An old bull eating young grass. He only cares about her looks. - Later: “Song Yu's started a factory!” “Song Yu's launched another new production line!” “Song Yu's been received by the leaders!” “Song Yu's made the papers!” From then on, whenever people mentioned Song Yu, their eyes held nothing but admiration and envy. [Content warning: She does not go to the countryside. The space is a System space and rarely appears. The male and female leads have a 14-year age gap!]
