This old man must be at least in his sixties or seventies, yet he addressed him as "young master," which a self-aware eighteen-year-old youth like him could hardly stand.
"Yes, young master!" Uncle Gui complied.
Ma Gui, at his age, certainly had some discernment and was definitely able to see the male-female relationship between Li Zhongnan and Sun Ruiyan. However, he could likewise tell from their behavior that she was likely just a servant to him, at best a concubine,
without his order, she would not dare to call herself "young mistress"!
"Uncle Gui, I'm new here and not very familiar with Pingyang City. Would you join me for a stroll?"
Li Zhongnan instructed.
"Of course, young master," Ma Gui nodded and led him towards the city center.
However, he was quite silent along the way. If no questions were asked, he wouldn't speak; when asked a question, his responses were mostly mechanical.
Just like a "system"!
