Jiang Ye, a seventy-year-old gatekeeper with a tragic past, was cast aside by the martial world for being too old to train—until a mysterious system awakens within him, granting him a full year of cultivation progress with each passing day. Once dismissed as a powerless, forgotten commoner, he secretly masters the ancient Five Animal Fist, achieving in hours what others spend years to learn. While the academy’s elite disciples bask in privilege and praise, Jiang Ye hones his hidden strength in the shadows, his body transforming with every dawn.

As his power surges beyond mortal limits, he begins to notice strange connections between his past, the academy’s hidden secrets, and the wounded master he once saved. With every nightfall, he grows stronger, wiser, and more dangerous—and the world that once mocked him will soon learn the cost of underestimating the old and the poor.
