Dark Boat Returns

Li Zhenglan, director of the Propaganda Department of the Provincial Department of National Security, was assigned to dig up red historical materials on the Pengxian Uprising and set his sights on the dangerous building at No. 37 Yongjing Lane, Shaofu City. This is suspected to be an underground communication station in 1949. The iron boxes, embroidery albums and copper buttons unearthed during the construction lead to the mysterious core figure codenamed "Zangzhou". Building restorer Shen Qing joined hands with Li Zhenglan to solve the problem through clues, but encountered obstacles and rumors from developers. With the support of Zhou Yu and the help of old neighbors, they cracked the code, discovered the secret passage, and gradually pieced together the secret lives of the seven people at the liaison station. When Li Zhenglan compared Su Nian'an's notes with the family archives, he was shocked to discover that "Cangzhou" was actually his grandfather Li Nianzhou, whom he had never met. The dusty family bloodline and the mission of the hidden front instantly intersected. Two generations of Guoan people, their ancestors and grandchildren, traveled through the fog of time and space with their original aspirations, and finally made the heroic deeds of this man who had been anonymous for decades public to the world, completing the protection of the family and country and the inheritance of the original aspirations that spanned half a century.
