Spiritual energy revives, demons run rampant, and superpowers rule the roost. Lu Chuan, a prequel martial arts genius who retired due to injury and made a living by delivering food, thought that Chinese martial arts was dead and that his dreams and passion had long been burned out. Until he punched through a concrete wall to save a blind girl, the video went viral. He was shocked to realize that this world nourished by spiritual energy was exactly the "era of great struggle" recorded in the ancient boxing manual! From then on, wearing a yellow robe, the electric car galloped between the steel jungle and the shadow of monsters. The gift is not only food and clothing, but also a kind of protection in troubled times. When the official Supervision Bureau extended an olive branch to him, when the Guwu family scorned him, when the tide of monsters and aliens swept the city, Lu Chuan just calmly put on his helmet and turned the switch. Behind him are the lights of thousands of houses; under his fist is the dawn. This is a story about a delivery boy using traditional martial arts to support ordinary people in the new era.
