After the "September 18th" Incident, the Japanese army built a fortress called the "Oriental Maginot Line of Defense" on the Sino-Soviet border. Anna, the Chinese adopted daughter of the Soviet general, sneaked into it for investigation, but was unfortunately caught by the Japanese army. The Northeast Anti-Japanese Alliance immediately sent Wenlong to rescue An Na. Among those rescued were magician Gao Xiaozhuang, hunter Hu Dazhuang, national army female agent Tan Zhuoru, Northeast Army officer Wei Kunning and others participated. When Wen Long rescued An Na from the prison cell in the fortress, the Japanese military officer Koizumi Kiyoshi led the troops to hunt down. Wenlong originally wanted to send Anna from the northeast of the Sino-Soviet border, but the Japanese army seemed to have guessed it and blocked the border ahead of time. Wenlong had to change his plan and send Anna to the pass. Anna held photos recording Japanese atrocities and secrets. In the process of protecting An Na, Wen Long led the crowd to destroy a series of Japanese military facilities, such as railways and drug factories, and found a large number of evidence of Japanese invasion of China. Hu Dazhuang, Tan Zhuoru, Wei Kunning and others sacrificed one after another to protect Anna. In the end, Anna was sent to a safe place
