1941, Shanghai, rainy season.
Heavy raindrops hit the bluestone on Xiafei Road in the French Concession, causing fine splashes of water that mixed with the halo of street lights to form a hazy net. Lin Mo was holding a black cloth umbrella and walking slowly on the sidewalk. His navy blue suit was ironed and straight, with an inconspicuous silver cufflink pinned to his collar - it was the liaison mark of the Shanghai District of the Military Command.
"Beep - it is detected that the host is in a mission environment, and the spy system is starting... The startup is successful."
The cold mechanical sound sounded in his mind, and Lin Mo didn't even raise his eyelids. This system suddenly appeared after he was hit in the temple by a stray bullet during an assassination mission three months ago. At first, he thought it was auditory hallucinations caused by brain damage. It was not until the system released the first task "Obtaining the patrol route of the Japanese gendarmerie stationed in Shanghai next week" and rewarded him with the "photographic memory" skill after completing it that he had to accept this absurd but deadly reality.
