"The Spy: Cold City" is a spy war-themed novel that tells the story of underground workers obtaining important intelligence during the Anti-Japanese War.
In the novel, in order to obtain the backup map hidden in the secret room on the top floor of the Ministry of Finance, Shen Yanzhi and Tian Mo found Su Manli, a "French Concession socialite" who appeared to be dependent on the Japanese army but was actually delivering intelligence to the anti-Japanese coalition forces. However, Matsui had just changed the locks on the secret room, had a new key in his pocket, and the Ministry of Finance had stepped up security. Tian Mo proposed to use ether to make Matsui comatose to obtain the key, and Su Manli took the opportunity to attend the Matsui family's dinner to implement the plan. Shen Yanzhi used the floor plan of Matsui's house, entered the dog hole in the backyard to get the key, and successfully obtained the map, but was discovered in the secret room by Xiao Lin, the deputy director of the Special High School Division. At the critical moment, Boss Zhang opened fire to distract Xiao Lin, and Shen Yanzhi and others escaped successfully. Su Manli also handed them the compiled information on the mobilization of Japanese troops, and then she prepared to leave Shanghai. Finally, Shen Yanzhi and others headed towards the anti-Japanese base area with maps and intelligence, while Su Manli got on the train to Chongqing.
