Modern young man Chen Mo accidentally traveled to Jinling in 1937 and became a low-level spy of the military. During a mission, his left eye mutated and he gained the ability to see through disguises and identify spies. With this ability, he accidentally discovered a Japanese spy base and made great contributions, but only received a meager reward due to his low status. Just as his sister was in trouble in Shanghai, Chen Mo accepted a secret mission and went to Shanghai. While taking care of his relatives, he survived in the whirlpool of espionage on the eve of the Songhu Battle. From a low-level person who was greedy for money and cared about life, to a spy elite who took charge of his own business, Chen Mo used his eyes to see through disguises, protect his loved ones, and fight his way through troubled times.
