In 1938, Jiangcheng fell. Lin Yi lurked as a reporter, but in fact he was responsible for the single-line liaison with the Four Spirits Alliance. Ichiro Yamamoto of Japan's Special High School is eyeing him, military commander Tie Feng woos him, and American and British intelligence officer Smith wants to take advantage of him. Once the connection failed, comrade Xiao Chen was arrested. In the interrogation room, Lin Yi put on another "vest" - the informant of the Special High School Course. He must use the sense of Qi Yun in the listening realm to find the flaw in Yamamoto's murderous intention. But every time I switch identities, the "rhyme" deep in my soul deepens. When he finally rescued Xiao Chen, he found that Lao Zhou had been crucified on the church cross. The aura came back, and permanent scars appeared on Lin Yi's right arm. He collected Lao Zhou's body and clutched the blood-stained pocket watch. The secret base of the Japanese, the top-secret plans of the United States and Britain, the spy of the military commander... All clues point to the "heaven pulse" hidden in the sky above Jiangcheng that can change the situation of the war. But he didn't know that Yamamoto had already laid a trap, just waiting for him to fall into the trap.
