In the Shanghai Concession in 1941, Shen Mo witnessed his superior being shot dead by No. 76. In order to save his life, he picked up the code pen and pretended to be a clerk to lurk in the Wang Pseudo Translation and Electronics Section. As a "lone wolf" of the military commander, he possesses the "fragmented memory recall" ability left by his superiors. However, because he is implicated as a traitor, he is hunted down by the military commander and monitored by the Japanese army. He is shocked every step of the way.
The temptation of the CCP liaison officer Su Wanqiu, the suspicion of Matsumoto of the special high school, and the coveting of the British and American intelligence agencies, all forces pushed him into the center of the whirlpool. When the Japanese military's "Plan to Clear the Countryside" was launched, the chemical weapons conspiracy surfaced. He held half of the defense map and the code in the modified pen, which became the key to crushing the conspiracy.
Memory retrieval was used to detect the plot of the inner ghost, and mechanical talent was used to dismantle deadly traps. Shen Mo circled around the wolf den of No. 76, Delivering information amidst the hail of bullets. When his identity is exposed and his lover is captured, can he unite the military and the Chinese Communist Party and use his life to tear apart the Japanese spy game in the darkness before dawn?
