An ordinary delivery boy {Li Yang} is running around for a living. On the way to deliver food, he encounters an injured martial arts master and is taught basic martial arts skills through his help. He accidentally awakened his martial arts talent and used his spare time to practice crazily. When a customer was robbed while delivering food, Li Yang tried his best to fight off the robbers for the first time, and has since embarked on the road of "delivering food + helping others". Time after time, he offended the local evil forces. In the face of retaliation and threats, Li Yang became braver and braver as he fought, and his strength improved rapidly. He started from a low-level deliveryman and counterattacked, and finally grew into a martial arts powerhouse that shocked the city. He not only swept away the evil forces, but also allowed his family to live a prosperous life, writing a martial arts legend of grassroots counterattacks.
