I Found Classified Secrets in the Scrap, and the Abstinent Officer Begged Me to Hand Them Over

[Period mystery] + [spatial rearrangement] + [powerful military family and marriage] + [intense push and pull] + [female lead who plays the pig to eat the tiger] What does it feel like to go scavenging in the hills in the middle of the night and accidentally piece together a cipher book used by enemy agents? Su Miao only wants to fill the bottomless hole in her spatial storage. But when she turns around, the black mouth of a gun is pressed against the back of her head. The man holding it is broad-shouldered and long-legged, dressed in military uniform. He's Lu Zheng, the cold-faced intelligence officer feared throughout the military district. "Where did you get this?" The man's rough fingertip brushes her delicate neck, sending a dangerous shiver through her. To stay alive, Su Miao is forced to begin an exciting daily routine of turning trash into treasure and catching enemy agents. She thinks it's all just an act, but later, the cold and abstinent man traps her in the back seat of a jeep. Their extreme size difference leaves her nowhere to run. His eyes are red at the corners, and his voice is unbearably hoarse. "The secrets belong to the nation. You belong only to me."
