Ye Qinghe, 18, has been completely paralyzed for three years, able to move only his eyes. He lives with his father, Ye Dali, in a tiny 10-square-meter rental room in an urban village. One stormy night, a system descends into his consciousness: every time he completes a 50-kilometer journey within his mental space, he gets one chance to draw a prize. His first reward restores the function of his right index finger, making his father burst into tears like a child beside his bed. His second reward grants him the abilities of a mathematics genius, automatically providing the next hint whenever he encounters a mathematical problem. Confined to his bed and armed with nothing but a mobile phone and the forum ID 'Towards the Sun,' he begins to rise above his circumstances. He solves mathematical problems that even postgraduate students in the mathematics department of Qingmu University cannot crack, initially mistaken for an ordinary janitor before being worshipped across the internet.
