Anti-Japanese War: 1941 Shanghai Secret Telegram

[Spy war + adaptation of real events + battle of wits + no system + high-end game] 1941, Shanghai during the isolation period. In the midst of the storm, there is a turbulent undercurrent. On the surface, it is the "Paris of the East", a place of sensuality and wealth, but in fact it is a capital of espionage where various forces compete. Shen Mo, an upstart in Shanghai, is the deputy chief inspector of the French Concession. He is a suave man who hangs around celebrities and is known as the "son of the concession." His true identity is the "nail" for the Military Command's deep dive. However, even his superiors don't know that he has another top-secret identity - codenamed "Duhe". His core mission is to obtain the Japanese military's top-secret plan called "Coral Heart" and find the spy code-named "Netherworld" lurking within the organization. The beginning of the story is a carefully planned "hero saving the beauty". Shen Mo "saved" Imai Masako, the only daughter of Imai Koichi, the head of the Japanese East China Expeditionary Army's secret service, from the harassment of Japanese agents. This chance encounter was his "opportunity" to break into the enemy's core, and it was also the starting point of all entanglements and pain. As the mission deepened, Shen Mo found himself trapped in a huge puzzle: Is his beloved fiancée an enemy? A respected mentor is a traitor? The espionage network he built with his own hands fell victim? In the fire of loyalty and betrayal, faith and emotion, he is like a lone crane, looking for a ferry in the endless dark night, using his life as a bet to play a big game called "family and country".
