Signed In For 50 Years: Wudang's Hidden Grandmaster

Lin Chuan, a transmigrator, found himself the lowest of the low at Wudang Mountain: a cowherd baby with zero cultivation aptitude. While \"geniuses\" like Wang Che trained fiercely, Lin Chuan was stuck herding buffalo, destined for a life of mundane obscurity in a world teeming with martial might. His fate shifted dramatically when a [Sign-In System] activated! Every day, at sacred Wudang locations, he'd sign in, instantly gaining legendary martial arts, ancient scriptures, and potent elixirs. His first reward? Zhang Sanfeng's 200 years of Inner Strength! In just ten years, the humble cowherd secretly reached Grade 1 Peak, a hidden Grandmaster! For fifty years, he remained the unassuming shepherd, Wudang's silent guardian. But with the Six Great Demon Sects gathering at their gates, preparing to unleash chaos upon the mountain, how much longer can Wudang's ultimate weapon remain a secret?
