Shanghai, the economic center of the early Republic of China, was under turbulent occupation, all forces from all over the world were concentrated here. The Japanese Consulate General in Shanghai, Ryukawa Ida, attempted to turn Shanghai into a Japanese-occupied special economic zone without any effort and kidnapped Mayor Luo Shuzhang. Qin Fang, a young man in the 21st century, accidentally came into contact with a time-travelling gadget made by his grandfather and time-traveled to this time. By chance, he joined the Jingwu Sect, and became an apprentice to Chen Zhen as his teacher. In order to divide the various forces in China, Ida used Matsumoto Kosuke to frequently challenge various Chinese martial arts schools. All the martial arts schools were defeated, and finally Jing Wu Sect was chosen as the next to be defeated. In order to get Chen Zhen to fight Matsumoto in the competition, Ida used Luo Shuzhang as a hostage to force Chen Zhen to participate in Matsumoto's challenge.
