The mention of the school as "Lai Jun City's Third High School" and the Han Federation suggests a specific geography. I'd like to know more about the Federation's structure: is it China in the future? A renamed state? The Three Shines history is global, but the story seems focused on this Han culture. The teacher's name "Old Zhan" and the cooking reference "Great Han Federation" authenticate the setting. It's clearly inspired by modern China with cultivation.

It grounds the story in a specific place and time, even if that place might be an illusion. The contrast between the lively market and Bai Mengjin's internal confusion about her situation creates a nice atmosphere.
