In 1943, in the foggy mountain city of Chongqing, Lu Zheng, an interrogation analyst from the National Security Bureau, unexpectedly crossed over to inspect the case under the supervision of the Major General of the Military Unification Secrets Division. The start of the investigation was in a dead end. Huangzhaoling's 317 soldiers were all wiped out. The tampered fatal telegrams, autographs, and complete personal and material evidence put all the blame on him. He only had five days left to prove his innocence.
Lu Zheng, who awakened to the lie detection and file decoding system, uncovered flaws in the layers of perjury, starting with scratched telegrams, black market drugs, and secret dead mailboxes, uncovering the undercover undercover and cutting off the surface spy Gao Zhikai. The "star position" code left behind by the mutilated power and the unknown radio station that appeared inexplicably in the city prove that the mastermind behind the scenes is still hidden among the top military officials.
He delved deeply into the confidential process, reviewed leaked secret messages, and identified Huang Suxin, a perfectly disguised translator who had been dormant for eight years, and found out the secret channels through which he used churches, medicine shops, and Bibles to transmit information. In the troubled times, the hearts of the military commanders are treacherous, and there are false schemes and deadly traps everywhere. Lu Zheng used his interrogation expertise to uncover lies and find the truth, tearing open the mountain city's undercover network. In the fog and murderous intention, he dismantled the treasonous conspiracy step by step, and guarded the intelligence defense line of the Anti-Japanese War.
What the hell!
