In the Dinghai County Customs Declaration Hall, Shen Xiuyun pressed the crease of a confidential Japanese letter, her fingertips feeling cold. In his previous life, he died during the bombing in 1942, and now he is reborn in the summer when the war first broke out. Japanese spy Masataka Washizu disguises himself as a trading company employee and is using smuggling lines to win over salt lords and purchase tungsten sand. As a first-level translator, Shen Xiuyun knew that as long as the six words "Pier 3 tomorrow night" in the secret letter were leaked, the entire ship of medicine would fall into the hands of the enemy. He took the risk of changing the message and causing Jiujin's ship to hit a mine. The first break is just the beginning. Special high school student Furuhata Kaku arrives in Zhangzhou with a more insidious series of traps, and the underground intelligence agent Lin Jinglan around him is also testing his background. Shen Xiuyun must use multilingual intelligence to counterattack the enemy while joining forces with guerrilla captain Chen Hansheng on the smuggling line. But he didn't know that the most fatal loopholes were hidden in the people he trusted the most.
