I Invent Things in Ancient Times and Raise Twelve Babies

[Farming + teaching and nurturing students + System space + infrastructure building + raising children + family life + no romance + unifying the nation] The heroine was kidnapped as a child and made into a child bride for a farming family. After her soul wanders through China for 27 years, it returns to her hometown. She chooses to stay in the village, raise children, and teach, building academies, orphanages, nursing homes, libraries... Building dams, increasing rice yields, developing looms and movable-type printing, creating clothing for all 56 ethnic groups... Making soy sauce, salt, cloth, and sugar herself so ordinary people can afford to eat and use them. - The people can't read? Then we'll introduce nine years of compulsory education, free of charge! - Poor families can't raise successful children because books cost too much? Then we'll make books so common they're everywhere! - Ordinary people can't afford soy sauce and vinegar made with salt? Then we'll teach them to make their own! - A small country on the border wants to cause trouble? Then let's wipe it out and unify the world's peoples! Villagers: Want to get rich? Build roads first, have more kids, and plant more trees! Children: Great towers rise from the ground! A glorious future depends on us!
