After Fleeing the Chaotic World, I Conquer the Land with a System

Also known as: I Conquer the Four Corners in a Chaotic Era; My System and I Love to Fight Each Other as We Build an Empire System + famine flight + superpowers + immense strength + farming and infrastructure + female warlord + no romance This is a chaotic age plagued by endless natural disasters, where people are as insignificant as ants and the land lies in ruin. War, famine, bandits, plague... Danger lurks at every turn, and crises abound. Qin Yue: I've killed zombies before. Why would I be afraid of people made of flesh and blood? From a post-apocalyptic world crawling with zombies to a chaotic era strewn with starving corpses, apocalypse veteran Qin Yue isn't worried in the slightest. Let's see how she carves her way through this troubled age and outshines all her rivals! You ask what she'll use to conquer the land? Will the superpowers she gained in the apocalypse do? Oh, and there's also a clingy, relentlessly chatty System that insists on tagging along, claiming to be both a brilliant strategist and a walking treasure trove. Qin Yue: A quest System? I can get food for completing quests, and I might even win a farm in a pocket dimension? “Regular quest issued: Host, please learn to hop like a zombie!” “Regular quest issued: Host, please find a yellow dog and beat it up!” “Regular quest issued: Host, please squat down and laugh, then stand up and cry!” Qin Yue: You could spend ten years with a blood clot in your brain and still not come up with quests this stupid! “Advanced quest issued: Host, please shelter five hundred refugees!” “...” “Super quest issued: Host, please start a rebellion on the spot and proclaim yourself ruler!” Qin Yue: !!! Huh? This one actually sounds promising! A feel-good power fantasy! This is a fictional setting, so don't nitpick the history!!!
