The Neighborhood Went Up in Flames After I Became a Security Guard

Ning Ci, a master assassin who failed to retire, transmigrated to a strange new world with her precious dagger. The people here fear plants, stay away from the ocean, and band together to survive at Base Four. Through hard work, Ning Ci finally landed a job on her third day: neighborhood security guard. Work location: Base Four, Neighborhood Four, Guard Booth Four Job duties: Keep unregistered mysterious visitors out of the neighborhood Benefits: Meals and lodging included, uniform provided, four days off a month (not just Sundays), monthly salary of 2,800 (with a year-end double salary) Ning Ci was very pleased with the job. “Simple and steady, perfect for taking it easy in retirement.” The residents were also pleased with their new guard. “Honest, polite, and cuts down monsters like she's chopping vegetables.” Ning Ci found a second wind in her career here. She turned down her boss's transfer notice and happily declared, “I like this simple job where all I have to do is fight. I'm going to be a neighborhood guard here for the rest of my life.” The next second, a missile fell from the sky, reducing Neighborhood Four to rubble in an instant. “Wait, I haven't even been paid yet!” she shouted, drawing her dagger in fury. 1. The heroine's perspective is very down-to-earth. To the big shots, everyone else is just an unremarkable little monster. 2. Everyone except the heroine has a life as fragile as a duckweed, and can die at any moment. 3. The worlds before and after the heroine transmigrates are both fictional; everything in the novel is invented. 4. A salary of 2,800 is really high! 5. There is only one one-sided romance, involving a male character. I don't think it strictly counts as no romance, so I've changed the category from romance to multi-genre. Theme: World peace
