In 1938, in a war-torn Shanghai, tabloid reporter Qiao Wansheng accidentally got involved in a spy war involving the Japanese military's top secret "Sakura Project" in order to pursue the truth behind her father's disappearance. On the surface, the "Sakura Project" was an economic plunder by the Japanese military in China, but in fact it concealed a biochemical weapons research and development conspiracy that could change the direction of the war. Qiao Wansheng relied on his extraordinary memory and keen insight to smell blood from each bizarre murder case.
Her investigation was thrilling at every step. Not only did she have to evade the strict pursuit of the Japanese military's special high school, but she also had to deal with layers of obstruction from the pro-Japanese faction within the Nationalist Government. What makes her even more painful is that her childhood sweetheart, a medical genius who returned from studying abroad, was coerced by the Japanese army to participate in the "Sakura Project" experiment! Qiao Wansheng must make a choice between "revealing the truth" and "saving her lover". She has no golden fingers, only wisdom, courage and sincerity for the country and the nation.
The concession patrol looked on coldly and the underground party intelligence officers loomed, making Qiao Wansheng realize that he was fighting alone. She used her identity as a tabloid reporter to travel among the three religions and nine streams, and under the pretense of singing and dancing, she collected ironclad evidence that could shock the international community. In order to expose the heinous crimes of the Japanese army, to prevent the development of biological and chemical weapons, and to ensure that his father's sacrifice is not forgotten, Qiao Wansheng must make this "empire's top secret" public in the rain of bullets. Even with flesh and blood, he must tear off the disguise called "peace" and let the fire of justice burn throughout the East!
