The plot follows Zhang Qishan investigating a ghost train carrying dead Japanese soldiers, uncovering a mine tied to ancient tombs, Japanese conspiracies, and supernatural threats, with subplots involving tomb raiding, brotherhood, and a conventional romance between Zhang and Yin Xinyue. All elements draw from traditional Chinese tomb-raiding fiction and historical fiction tropes without any overlay of contemporary social commentary.

The series maintains a traditional 1930s Chinese historical setting and plot focused on adventure, mystery, national defense, and tomb raiding, containing no identity politics or systemic oppression narratives. Casting consists of Chinese actors in era-appropriate roles matching the source novel, with female characters like Yin Xinyue and Ya Tou placed in conventional romantic and supporting positions justified by the story. There are no creator statements, dialogue, or subplots addressing DEI, gender fluidity, LGBTQ themes, or critiques of traditional norms. Reception shows popularity for entertainment value alone, confirming the absence of progressive messaging.
