[Urban Imagination] + [Apocalypse] + [Multiple Heroines] + [Near Future] + [Technology-Focused] In 2027, an alien civilization arrives, and Earth's environment undergoes drastic changes. Human women awaken genes that enhance their physical cultivation, their strength surges, and they become the main force in fighting external enemies and expanding humanity's living space. Men's physical evolution is limited, so they move into auxiliary and logistical roles. Society is turned upside down overnight, without discrimination: people simply have different roles.
Twenty-two-year-old Qin Yu is one of countless ordinary workers. He's not tall or flashy. His only distinguishing traits are that he speaks little, has steady hands, is highly intelligent, and knows how to keep a low profile. No System, no rebirth, no memories from some big shot. He only wants to repair equipment in peace amid the chaos.
Until one night, after getting drunk, he spends the night with Aliya, a three-meter-tall alien female war goddess, though he's too dazed to understand what happened. Afterward, Aliya deliberately starts sending him damaged alien equipment to repair. Through it, Qin Yu gains access to advanced technology and gradually pieces together the truth about the aliens' plans to modify Earth: they aren't colonizing it, but fleeing the "Harvesters" deep in the universe.
Starting with a broken water purifier, Qin Yu gradually builds an underground repair network called the "Mechanical Mutual Aid Society," quietly supporting the women's combat forces in their ongoing battles. The three romantic storylines with genius mechanic Lin Wei, awakened human Su Jin, and alien war goddess Aliya heat up rapidly as they fight together.
He has never charged into battle, but his shadow lies behind every victory.
This is the story of a repairman who uses a screwdriver and his intelligence to connect two civilizations and repair a machine called "the world."
