Codenamed "Silent", his ability is "memory playback" with photographic memory. When the video of his fiancée's murder replayed in his mind for the hundredth time, Ji Wenmei realized that she had been betrayed by her most trusted comrade. Being framed, wanted, hunted, and trapped in the desperate situation of an enemy prisoner-of-war camp, he used the data of a bowl of rice soup every day to calculate the time for changing defenses, mapped the patrol blind spots with thirty-seven notches on the corners, and broke the necks of three guards with his bare hands before dawn when everyone thought he was about to be executed. When the headquarters received the secret message that "Black Crow is online and is about to return home", he was sitting in his new boss's office drinking tea with the batch of "Sea Wolf" drawings that had been missing for half a year. Tomorrow, he will join the hunting team targeting him in the name of an enemy agent.
