In this short scene, we get a brief description of Zhang Haigen, the main character of the story. He's in the middle of his mission, and he's on the move. He wants to show off his armor, so he asks the guards if they're the only ones living in the house. They're not, but they've been spying on him all along. Zhang asks if they can spy on him, and they say they can, but he'll have to alter his identity to be able to do so. He also wants to know if the guards know his real name, so they can trust him.
