In a prosperous city where martial arts and technology coexist, {Chen Fan} is just an ordinary office worker who works from nine to five. While working late at night on the streets, he accidentally binds to the "Martial Arts Supreme System". The system issues tasks, gives martial arts skills, and provides training resources, allowing him to step onto the road of martial arts from a helpless social beast. Solve workplace bullying, resolve street crises, participate in the much-anticipated urban martial arts competition, and compete with geniuses from major martial arts families and hidden masters. With the support of the system and his own fierceness, Chen Fan counterattacked all the way, breaking down class barriers, and finally reached the top of urban martial arts, becoming a legend who protects urban peace and stability, and composing a passionate martial arts journey from ordinary to supreme.
