Wei Xiu, the owner of a township maintenance shop, has a talent for systems and is proficient in maintenance, but he accidentally gets involved in military affairs. He first upgraded the Hongqi 9 missile vehicle radar and shot down an invading F35 fighter jet without receiving military orders. Although he was detained for disobeying orders, he gained the attention of the military for his technological breakthrough. Later, he declined the professorship at Harbin Institute of Technology and took over the F35 reverse research and development task. At the same time, he insisted on live broadcasting to increase his fans, and modified the old man's music to arouse heated discussions. With his extraordinary technology and humorous personality, he wrote a legend between the civilians and the military.
