Lu Chengyuan, the top modern special forces soldier, died in a cross-border anti-terrorism operation. His soul traveled to Shanghai in 1937 and became a handsome student in the military command temporary training class - the nephew of a military and political boss with the same name. The original person killed an entire escort team due to cowardice in actual combat, and was being ordered by Dai Li to "pay for his crimes and perform meritorious services."
At a critical moment, the [Spy War Deduction System] is activated:
"It has been detected that the host is surrounded by Japanese agents, and the optimal escape plan is being deduced..."
"Successfully killed the Japanese spy major and received the reward: proficiency in Japanese + shell gunner level proficiency!"
"Successfully cracked the secret code and unlocked the skill: micro-expression detection (can see through lies)!"
From then on, Lu Chengyuan transformed into the military commander's "living king of hell": he pretended to be a Japanese businessman and took down intelligence dens, used the power network in the concession to set up a bureau to pick out traitors, used criminal investigation thinking to uncover the military insiders, and even converted smuggling profits into anti-Japanese funds. He traveled among the three forces of the Japanese puppets, the military command, and the underground party. He systematically deduced the battle situation with his left hand and took the enemy's head directly with the weapon in his right hand.
When the top spy nicknamed "Sakura" lurked around him, and Dai Li's suspicion followed him, Lu Chengyuan sneered and drew his sword: "In the chess game of espionage, I am both a chess player and the king of hell!" From the swords and shadows in the Shanghai Concession to the undercurrents of the Nanjing puppet government, he used blood and fire as ink to write his own legend in the history of the Anti-Japanese War.
