Chen Yun knelt in front of the Japanese major, and reported in a fluent Kyoto accent: "The front is the military command den." The major nodded with satisfaction. Three seconds later, a bullet slipped out of Chen Yun's sleeve and penetrated the temple of the traitor next to him. He is the leader of the intelligence team of the Juntong Southeast Station and can speak twelve dialects and four languages. There is only one task tonight: at the Japanese army's celebration banquet, use language as a knife to cross out the names on the traitor list one by one. After the first cup of tea, the president of the Chamber of Commerce died suddenly. In the second sentence, the puppet army commander committed suicide. At the third signal, all the opium in the warehouse spontaneously combusted. But Jiro Yamamoto sensed danger. He pulled out his saber and put it against Chen Yun's throat: "Who are you?" Chen Yun smiled slightly and said in a pure Tokyo Shitamachi accent: "Your dog, a dog that can bite." The next second, he bit the cyanide capsule in his mouth - of course, it was fake. The real killer move is hidden in the information to be delivered tonight. Rape is just the beginning. In this world where there is one traitor for every three agents, language is his only weapon and a talisman to kill him. Within 24 hours, he must find the real mole among the three "own people", otherwise the entire Southeast Intelligence Network will bleed into a river of blood. Tonight, he wants everyone to know that you can live if you talk, but you can kill if you say the wrong thing.
