The Immortal Girl's Sign-In System: Eons Pass, I Stand Unrivaled

She wanted scrambled eggs—she got eternal life instead. Lin Yue, a modern programmer, transmigrates into the frail body of a drowned village girl sold as a child bride to a dying man. Armed with nothing but an immortality cheat and zero combat perks, she takes the slow road: studying medicine, mastering martial arts, and quietly cultivating through the ages. While empires rise and fall, and everyone she's ever known fades into dust, Lin Yue perfects the art of lying low. No drama, no spotlight—just centuries of steady grinding until she stands at the summit, untouchable and unbothered.
