Transmigrated as the Wicked Mother-in-Law, I Lead the Whole Clan to Flee Famine

{Alternate world + lucky koi pocket dimension + flight from famine + infrastructure building + no romance for now} An overworked modern illustrator becomes a wicked mother-in-law in a rural village. From the start, she's selling her sons and daughters and drawing the fury of the entire village. And that's not all: war breaks out, and they have to flee. She feels like she's done for. Just as she loses all hope, she awakens the Lucky Koi Space System. Her luck goes through the roof, and she gathers a mountain of supplies. She leads the whole village to the northern border, a place everyone fears. As they stare at the endless desert, the villagers all look at her. She thumps her chest and shouts, “Don't be afraid. Let's do this!” Before long, houses spring up one after another. Before she knows it, they've built a city, and she's become its female lord. As she watches more and more people put down roots there, even the emperor comes to attack. The heroine rides out on horseback, weapon in hand, facing the emperor across the field. She feels utterly exasperated. “All I wanted was to live a quiet little life. Why is that so hard?”
