[White Hair, Red Eyes, Hard-Boiled Protagonist + Not Hard Sci-Fi + Alien Misadventures + Bethesda’s Starfield + Arknights Fanfiction + Serious Farming + Fleet-Building + No Cultivation + No Fantasy + Pure Sci-Fi] Long, long ago, a Blue Star developed a magnificent civilization. Spaceships roamed the universe, and the sun was held captive by artificial structures. One day, a battle starship carrying a girl who had been a girl for decades, along with two transmigrators from different worlds, arrived in a strange world. To survive, they had no choice but to work together and face whatever enemies might come. But when they stood ready for battle, prepared to make the ultimate sacrifice, what flew out of the hyperspace lane but a few wooden ships? What? Humans are actually the strongest civilization in this galaxy? From then on, the civilizations of the galaxy cried out in alarm: “There’s a bunch of hairless freaks on the edge of the galaxy. They destroyed their own home planet for the sake of war. They’re brutal. They bring death. They’re invincible. They are... humanity!”
