The Yellow Immortal spirit, Huang Er Ye, accompanies her and can read the past of objects. Her family dismisses her as someone who dabbles in superstition, but she uses mystical knowledge and antique appraisal skills to repeatedly prove them wrong. Gu Yanzhi, a young warlord commander, joins forces with her to investigate stolen national treasures. As the fake heiress causes trouble and the Tong family traffics in cultural relics, Xu Zhixia solves cases and recovers stolen treasures. She grows from a village fortune-teller into the Governor's Mansion's renowned supernatural detective, while the young commander falls for her first and showers her with affection.
