Chen Ting, the liaison officer of the Western Intelligence Agency, was ordered to sneak into the secret platform to assist the anti-special forces in the name of restoring the ancient buildings of Fenghuang Terrace. After the first encrypted military intelligence was sent, the enemy launched a precise raid on Zhichuan Ferry, confirming that the traitor had mastered the core password. Chen Ting used his familiarity with architectural features such as the "Double Phoenix Eyes" iron tower of Phoenix Tower and the boat-shaped monument base to discover traces of abnormal radio waves. In the process of investigating the translators, telegraph operators, and logistics personnel, the shadow of the military commander's "counter-use plan" emerged, and Jing Che, the translator who had been captured and returned to the army, was full of doubts. When Chen Ting cracked the secret code of the legendary "Nongyu Chuixiao", he discovered the identity of the traitor and the truth about the destruction of the Four Secret Towers, which formed a shocking reversal, and finally started a life-and-death confrontation amidst the sound of air defense sirens.
