I Was Dumbfounded When I Went to No. 76 to Be an Undercover Agent.

During the Anti-Japanese War in Shanghai, No. 76 Jisi Feier Road was a "devil's cave" that everyone talked about, but Lin Xiaoman, a common citizen, was forced to use a copy of "The Romance of the Three Kingdoms" as a code book by the underground party, and he became an undercover agent here. He has no special agent skills and only knows how to repair pens and abacuses. His code name is "Abacus" - meaning "survive by calculating carefully", but he does not want to start a ridiculous life of "surviving while being dumbfounded" in a murderous cave. On his first day on the job, Lin Xiaoman sprinkled sugar on the confidential documents of Intelligence Director Wang Manchun, and was frightened out of his wits by her cold eyes; when delivering documents to Operations Director Liang Zhongchun, he saw him counting gold bars, and was arrested to keep an opium account, his hands shaking like chaff; he wanted to exchange passwords with his colleague Chen Shen, codenamed "Sparrow", but because of nervousness, he picked up the wrong number of pens, and was regarded as a fool by Chen Shen. He was forced to be cannon fodder in the battle for orchids between Wang Manchun and Liang Zhongchun, and accidentally resolved the crisis by saying that "the flower's roots are too dense and affects the future"; when translating for the Japanese plum agency, he said "the military fortune is long-lasting" as "the business is booming", which made the major laugh, but Wang Manchun almost saw through the accent; he was even sent by Chen Shen to steal toilet paper because there was a Japanese army defense map on the package... In this devil's cave full of conspiracies and killings, Lin Xiaoman relied on his ability to "pretend to be a grandson" and his cleverness to deal with the ruthless Wang Manchun, the greedy Liang Zhongchun, the mysterious Minglou, and the cruel Ye Xingcheng. While being frightened, he opened the password box with his pen repair skills and stuffed the information into the dough sticks to hand over.
