The Savior Is Impossibly Adorable [Worldbuilding]

After a disaster, human civilization is utterly destroyed, and the survivors struggle to stay alive on Earth. Then one day, they discover a mysterious place: While everyone else is digging up roots and eating wild greens, the people here are having barbecue and drinking beer. While others fight with rocks, the people here fight with gunpowder. And while everyone else is worrying about getting enough to eat, the residents here are already discussing the next generation's education. Everyone: ??? How is this possible! And the savior whom everyone here reveres like a god is just a little girl. * The powerful AIs created by scientists to preserve human civilization have finally welcomed their first human master. But when they look at the little girl before them, as round and soft as a snowball, they all fall silent. Um... isn't she a little too young? [Current mission updated] Preserve human civilization, starting by raising a human child. #TakingDadAlongToBuildOurHome# (2020.10.22) Theme: Lead the whole village to prosperity.
