Autumn 1939, Jiangling City. The Japanese 112th Division ruled under the Iron Curtain, and the puppet army, military commanders, central commanders, and the Youth Gang strangled each other. Shen Hengzhi, a doctor of the New Fourth Army Health Corps, was ambushed when he was moving with the team. The entire team was wiped out. Only he was rescued by the underground party Lao Jiang. Before Lao Jiang disconnected, he left a message: "Go to Yamada Shoichi, he is one of ours." Before Shen Hengzhi found the connection point, the traitor Fang Ming had already sent his portrait to the Japanese military police. The whole city is being searched and there is no way to escape. On the verge of death, his brain suddenly exploded with severe pain - the false identity generation system was activated. The first vest: "Intern of the Manchurian Railway Investigation Department, Takeru Sato." System prompt: You must obtain a full railway certificate within 72 hours, otherwise your identity will become invalid and can never be used again. Shen Hengzhi sneaked into the Manchurian Railway Office, only to find that Fang Ming was leading the gendarmerie to search every office. There was only a corner left in the corridor, and Fang Ming's footsteps were getting closer and closer. He looked down at his white coat - it was still stained with the blood of his New Fourth Army comrades. The system pops up: "An enemy unit has been detected, it is recommended to switch identities. The remaining available memories: hometown ancestral hall, mother's face, sister's braids... Consume one segment to generate a new vest." Shen Hengzhi closed his eyes. He chose his sister's braids. When he opened his eyes again, the new identity had been loaded. He took off his white coat, opened another door, and spoke calmly to the person inside: "I am the liaison officer sent by the Japanese Anti-War League, codenamed 'Crane'. I want to see Yamada Shoichi." Outside the door, Fang Ming's search had just begun.
In the autumn of the twenty-eighth year of the Republic of China, ten miles north of Jiangling City.
