In a World with Few Men, I'm Thriving in the Post-Apocalyptic Wasteland

[Wasteland world + far more women than men + duck soup + species exploration + territory development + apocalyptic conquest + cyberpunk] Special forces soldier Qin Yang transmigrates to a wasteland world where the ratio of men to women is severely imbalanced. A peculiar pathogen is steadily weakening men's physiques, turning Qin Yang, with his solidly muscled build, into a rare treasure. To keep the pathogen from reducing him to a sissy, Qin Yang has no choice but to take advantage of the version's perks, all while setting out to explore the wasteland world.
