Wang Chenfeng, a top modern agent soldier, was about to retire from the army when he was on his last border anti-terrorism mission. He was attacked by a terrorist bomb and accidentally traveled to the early days of the fall of Shanghai in November 1937. His soul passed through the body of "Lu Chen," a peripheral intelligence agent of the underground party of the Chinese Communist Party who had just died. Lu Chen was originally the owner of a local silk and satin shop in Shanghai. He used his identity as a merchant to cover up the transmission of information.
