In 1937, there was an undercurrent in the Shanghai Concession. Modern intelligence analyst Shen Yan traveled through time and became a translator at the bottom of the Japanese military's special high school course, and awakened the [Intelligence Tampering System] - touching the target can generate "false intelligence data packets", completely distorting the enemy's secret messages, files, and eyewitness testimonies!
Faced with the suspicion and scrutiny of the head of the Special High School Course, he tampered with the interrogation records and turned the traitor's perjury into the confession of a Japanese mole; when he was surrounded by the military's anti-trafficking team, he forged a secret order to let the pursuers turn against him and raid the Japanese arsenal; when the underground party liaison station was exposed, he modified the radio frequency record and directed the search to No. 76 Demon Cave.
From a small translator in the concession to an "intelligence star" of the Japanese army, from a "blacklist target" of the military commander to a "mysterious ally" of the underground party, Shen Yan used a tampering pen to set off a spy war storm in the cracks between the Japanese puppets, military commanders and the Chinese Communist Party. When the Tokyo base camp was deploying troops based on his forged "Songhu Defense Plan", and when Dai Li was cleaning the interior with his tampered "spy list", Shen Yan stood on the top of the Broadway Building and sneered: "The true meaning of intelligence warfare is not to obtain the truth, but to create the 'truth' that the enemy believes."
