Invisible Blade

In 1937, the Battle of Songhu broke out, and Japanese teacher Shen Rumo was involved in the underground intelligence world by a blood-stained button. Under the guidance of the policy of "concealing capable personnel and long-term ambush", he broke into the Japanese Consulate in Shanghai and became a latent with a special status. At the same time, Lin Ruolan established a traffic station as a "fake couple" and hid information in braids and cream bottles; Zheng Yunshan sneaked into the Manchuria Railway Office to obtain strategic secrets from the enemy's heart; Zhang Luping established a "red radio station" at the Juntong Telecommunications Station, sending out radio waves. However, the moment before dawn is the darkest: Zheng Yunshan died heroically after being arrested, and Zhang Luping died generously singing "The Internationale" in Xifeng Prison. Shen Rumo continued to lurk despite the reputation of being a "traitor", while Lin Ruolan completed passes time and time again on the verge of life and death. They may not have names engraved on the inscriptions, but they use their flesh and blood to forge invisible sharp blades that penetrate the darkness. This is an espionage epic about faith, sacrifice and silent oaths, paying tribute to the real heroes who remain anonymous in the gaps of history.
