Li Chaoyang, the captain of the Anti-Japanese Imperial Emergency Unit, was masked and "invited" to the secret headquarters of Harbin Special Committee to accept new combat tasks, eradicate Noda Yoshihiko, director of the Japanese Institute of Biological and Chemical Weapons, and completely destroy Noda Yoshihiko's achievements in developing biological and chemical weapons. Since the last assassination failed, Noda Yoshihiko, a typical suspicious and cruel war maniac, has become more secretive. In addition, the residence of the Japanese Institute of Biological and Chemical Weapons is secret and heavily guarded, which makes it more difficult for Li Chaoyang to hunt wolves. Li Chaoyang returned to the space station and called the stormtroopers to study the action plan. Just as the stormtroopers were caught in the dilemma of how to find the Japanese Institute of Biological and Chemical Weapons, a recruitment news lit up the light for the stormtroopers. In order to expand the scale of the institute, Noda Yoshihiko recruited coolies to step up the production and expansion of masonry, and Li Chaoyang and "parents" took the opportunity to mix in. However, Yoshino is secretive and cunning, and the coolies who transport bricks and stones can only reach the entrance of the institute, and people outside the Japanese army are not allowed to enter. Li Chaoyang was disappointed that it was difficult to get into the research institute after being mixed into the brick kiln factory.

At this time, a new opportunity was placed in front of the stormtroopers. Noda Yoshihiko's precious daughter, Miss Youzi, loves Chinese Peking Opera very much and often goes to various lobby meetings in Harbin. In the troupe where Jinhua once studied, Mr. Fang seized the opportunity and took advantage of the chaos in the church to find the lost Miss Wanderer back. Yoshino, who lost his daughter, was furious and delirious, which won precious time for the stormtroopers to destroy the achievements of Japanese biochemical weapons. The Japanese Gendarmerie Command expelled fake military and police agents and searched the whole city for the lost Miss Wanderer. Mr. Fang and Jinhua pretended to be husband and wife, and handed the wanderer over to the Japanese gendarmerie. Miss Wanderer invited them solemnly. Noda Yoshihiko held a grand party in the Institute for the safe return of his baby daughter, and warmly invited the troupe and Mr. Fang Jinhua to perform as guests. At the invitation of Miss Tomoko, Li Chaoyang and her party visited Master Jinhua and joined the Institute of Yoshinoda as a pianist of the troupe. Due to the big meeting in Yoshino, the Japan Institute of Biological and Chemical Weapons is very busy. For the anti-Japanese stormtroopers mixed in the troupe, the cunning and secretive Yoshino has long been wary. On the day of the meeting, Li Chaoyang and Jinhua, accompanied by Miss Youzi, visited the Institute and secretly scouted the specific location of the chemical and biological weapons laboratory. In the evening, gongs and drums were loud and brightly lit in the institute, and Jinhua and my sister performed together on the stage. Under the stage, Li Chaoyang and others entered the secret laboratory, cooperated with the "old thief" and "old rope" who were in charge of the peripheral rescue mission, turned all the research results of Noda Yoshihiko's biochemical weapons into torches, eradicated the war madman Noda Yoshihiko, won the final victory for War of Resistance against Japanese Aggression and China, and made immortal contributions.

During the period of War of Resistance against Japanese Aggression, the Japanese army set up a research institute of bacteriological weapons in Northeast China in an attempt to kill my compatriots through inhuman bacteriological warfare. The anti-Japanese stormtroopers were ordered by the organization to eradicate Yoshinoda, a professor of bacteriology, the leader of the Devil Institute, and destroy the Institute of Bacteriological Weapons. Noda Yoshihiko is eccentric and suspicious by nature, and it is extremely difficult to get in touch with him. The stormtroopers cleverly designed it. On the occasion of the church meeting, they disguised themselves as Peking Opera artists, joined the Institute of Bacteriology, found the experimental base and blew it up.
