Qin Shi is a senior high school student in Taian Metropolitan Area, scraping by on summer jobs at a gym and a youth palace martial arts class. He lives in a cramped room in the dilapidated Old City District with memories of a lost family, and he cannot afford the expensive Life Force Development training that his peers take for granted. A mysterious panel silently tracks his daily efforts, logging nutrition, training intensity, and growth, yet so far it only rates him F.

Determined to change his fate, Qin Shi visits his old teacher at a vocational school on Old Factory Street, hoping to find a viable path forward. As he navigates part-time work, childhood friendships, and the quiet struggles of the working-class district, the panel's cryptic evaluations hint at a far greater destiny waiting to be unlocked.
