In the late autumn of 1935, three secret room deaths occurred in the French Concession in Shanghai. Next to each corpse was a bronze medal engraved with a candle dragon pattern. Shen Jinglan, the "lone star" of Teko who was lurking in the patrol room, was ordered to intervene, but found that the code on the bronze medal pointed to a long-lost "Candle Shadow File" - a top-secret plan compiled by the Japanese military for ten years, including a spy network in China, a biochemical experiment base and the distribution of strategic resources. There were ten fragments in total, hidden in ten mysterious objects.
Juntong, No. 76, Japan's Special High School, the Youth Gang and even the Soviet Intelligence Agency were immediately involved. Shen Jinglan had to form a temporary alliance with the military assassination master Lin Mobai, the singer Gu Wanqing whose identity is a mystery, the cryptographic genius Qin Shu, and the double agent "Butterfly" to solve one fatal mystery after another on the isolated island of Shanghai, the ancient house in Peking, Nanjing secret files, the Wuhan shipwreck, the gun smoke in Chongqing, the Hong Kong studio, and the jungles of northern Myanmar.
And when he finally put the pieces together one by one, he discovered that the "Zhu Yin File" itself was a trap to lure everyone into the trap - the real Zhu Yin was never a file, but a "civet cat changing the day" plan that lasted for more than ten years, and Shen Jinglan's life experience was the key to unlocking the ultimate truth.
