Beginning
Introducing the protagonist and golden finger: the protagonist Lin Feng, a marginalized person in the history department, is obsessed with "The Classic of Mountains and Seas" but is criticized by the professor as "not doing his job properly". While sorting out a batch of "suspected documents from the Western Regions of the Han Dynasty" that had just been donated (or ancient jade slips found at the flea market), a golden finger was accidentally triggered (the system was activated/the jade slips glowed/produced a strong intuitive image).
First recognition of "mistake": Golden Finger clearly reminded (or the image showed) Zhang Qian's huge inner uncertainty and confusion about the description of "Yu Benji" when he reported the source of the Yellow River in Hotan (Sima Qian's doubts were materialized). The protagonist is shocked by the historical truth that subverts his understanding.
The first challenge and slap in the face: The protagonist raised questions in class/academic salon and quoted classics (use the materials you provided: Hotan's low altitude cannot be the source of the Yellow River, the distance in space is too far, Sima Qian's records), and was ruthlessly laughed at by professors and classmates ("You know better than Zhang Qian?", "Grandstanding!"). The protagonist is frustrated. The system issues a task: "Preliminarily correct historical fallacies, obtain 100 Kunlun points/charge 10% of the jade slip."
Looking for a breakthrough: The protagonist uses golden fingers to analyze ancient books ("The Biography of Emperor Mu" points to Kunlun Sai in Gansu? Sima Guang's point of view?), Or the golden fingers directly point to the concepts of "weak water" and "enchantment". He realized that Kunlun is not an ordinary mountain, and the key lies in "boundaries". First contact with "abnormality"
