In the autumn of 1937, the Japanese invaders invaded North China. The Gu Family Fort was reduced to scorched earth overnight, and thirty-seven members of Squire Gu Yanqiu's family were brutally slaughtered. Only the 17-year-old eldest daughter Gu Changying was caught in the sea of blood and corpses by Masao Chiba, the head of the Japanese Super High School. The unquenchable ferocity in her eyes was the "uncut jade" he had been looking for for many years.
After three years of traveling eastward, Gu Changying had his name erased, his memory sealed, and was reborn as "Qianye Ling". Shooting, fighting, telecommunications, disguise, seduction... She was forged into the sharpest dark blade in the super high school, codenamed "Ice Butterfly". In 1940, Chiba Ling was stationed in Shanghai and lurked as a Japanese reporter. His mission was to strangle the underground anti-Japanese intelligence network in Shanghai.
Her opponent is Huo Jingheng, the head of Shanghai intelligence of the underground party of the Communist Party of China - publicly identified as the commissioner of the Economic Department of Wang Puppet, he is gentle and elegant on the surface, but in fact he has a lot of tricks. The fire of invasion and the water of night are at every step in the dance of Paramount, in the ticking of coded telegrams, and in the pursuit and counter-attack on the front line of life and death. He saw through her disguise but did not reveal it, she pointed a gun at him but was always soft-hearted; beneath the mask, feelings grew like an undercurrent.
An accident opened the cracks in memory. Holding an old photo, Huo Jingheng helped her find her name, her parents' faces, her younger brother's cry, and the wet blood beside the fence of the night well inch by inch. The kindness of nurturing is false, but the hatred of destroying the family is real. When "Qianye Ling" became "Gu Changying" again, she was torn apart between grudges and grudges, and was reborn in faith and love.
