High Martial: Bound to the System at Seventy – The Stronger My Grandson, The Stronger I Get

In a high-martial world overrun by ferocious beasts, bustling cities stand in stark contrast to the roars of monsters beyond the walls. Martial artists reign supreme. To give his grandson a shot at the prestigious martial arts university entrance exam, seventy-something Chen Mo takes on odd jobs to scrape together the fees. But the registration alone costs a staggering hundred thousand—far more than he could ever earn. His grandson, Chen Yu, is a sensible boy who offers to give up his dream to ease his grandfather's burden. What Chen Yu doesn't know is that his grandfather has quietly awakened the "Golden Years Nurturing System." The rule is simple: Chen Mo will always remain three major realms above his grandson. As long as Chen Yu puts in the effort, Chen Mo can lie back and advance without lifting a finger. While Chen Yu sweats through midnight stance training, Chen Mo sips tea and perfects his stances effortlessly. While Chen Yu grits his teeth through sword drills, Chen Mo strolls with his bird and masters the blade on his own. So go ahead, dear grandson—raise all the hell you want. Grandpa will always have your back.
