I Formed an All-Female Fleet from the Start and Conquered the Apocalypse

[Natural disasters + apocalypse + from the start + stockpiling supplies + no bleeding-heart heroics + decisive and ruthless] The Great Cataclysm begins, bringing one disaster after another: meteorites, tsunamis, extreme cold, volcanoes, hurricanes, biological mutations, and more. Lin An survived five years of the Great Cataclysm before returning to three months before it began. After merging with the Shipgirl Collection System, his very first mission is to build a starship! A meteor striking Blue Star will cause massive earthquakes? What does that have to do with me, flying around in the sky? A tsunami surges in and floods the land? Sorry, I'm aboard a starship. Thanks for asking. A mini ice age arrives, global temperatures plummet, and the continents freeze over? Ah, barbecuing while watching the girls dance is the best! The volcanic eruptions, hurricanes, and other natural disasters that follow can't touch Lin An, high above the world. When the disasters pass and humanity emerges from its underground cities, they discover that every living thing on the planet has evolved. That's when Lin An brings his shipgirl squad down to reap the rewards. The gentle and charming big sister An Nan controls psychic powers, killing without a trace. The fiery-tempered, proud Shen Yu is accompanied by a divine phoenix, burning away every impurity in the world! The cool and ruthless big sister Long Wanjun, a woman of few words, has a dragon-transformed body and peerless martial arts skills. She smashes everything! And there are plenty more girls, each with her own unique qualities. Lin An? What a joke. He gets to live off his girlfriends in rotation, with a different meal every day of the year.
