My Immortality is a Marriage Trap

Shen Xuan transmigrated into a nightmare: a gender-reversed world where fierce, powerful women rule, and men are delicate, sought-after 'house-husbands.' As a stunningly handsome young master, his family is determined to marry him off, and a 'trash' fiancée has just challenged him, vowing to become the nation's strongest to claim him as her 'prize husband.' Humiliated and trapped, Shen Xuan yearns for a normal life, but this world won't let him. Then, his terrifyingly powerful elder sister casually bestows upon him a 'Longevity Pill'—granting him infinite life essence. With eternal life on his side, Shen Xuan now has all the time in the world to cultivate. His goal: defy societal norms, become an unshakeable immortal powerhouse, and escape the fate of being a mere ornament. But in a world where men are valuable commodities, how long can he hide his overflowing vitality before the truly ancient, domineering female cultivators come seeking their own 'longevity furnace'?
