[Picture of a burning nightingale in Shanghai] On a winter day on the beach in Shanghai, Shen Qingli tightly wrapped her mink velvet coat, and a silver lighter turned out blue flames at her fingertips. Hidden deep in the flames was the secret message she had just deciphered. Japanese warships are arriving in Shanghai tonight.
As the literary and art editor of Shanghai Daily, she uses poetry reviews to convey information; as the ace agent code-named "Nightingale", she is using a scalpel to accurately remove the microfilm from the traitor's neck. When the blood spattered on the snow-white mink fur, the system's "zero" mechanical sound suddenly sounded: "Mission change: Obtain Gu Xingye's emerald pocket watch within three hours."
She chuckled and wiped away the blood. The gentleman doctor whom she always met by chance in the salon carefully bandaged her burned fingertips last night, but he didn't know that the poisonous needle hidden in his pocket watch had already been locked. When she pretended to faint and fell into his arms at Paramount, Nanzo Yunzi was using a magnifying glass to examine the cutout of the cheongsam she had published in the pictorial. Three southern-style pistols were gradually lined up on the desk.
Detective Chen Mo's copper pipe was knocking out intermittent signals in the patrol room. The silver lighter and the pocket watch are about to collide, the nightingale's song penetrates the fog, and all identities are shattered into millions of mirror fragments at the stroke of midnight.
