Relying on the skills of acupuncture and medicine, she saved the Queen Mother, defeated witchcraft, and cured epidemics. She rose from a low-ranking concubine to become the emperor's favorite. However, while falling in love with the sinister prince Xiao Chengji, he discovered that the pinch mark on his neck hid a murder plot, which also involved Xirong totem tattoos, gold mine maps of previous dynasties, witchcraft dolls and other shocking mysteries.

In the end, the emperor hired Jiangshan, but she chose to guard the imperial mausoleum alone with "Fengqi Fang". When the snow fell on the ginkgo trees, the whistle of the modern ambulance penetrated a hundred years of time, leaving an eternal suspense about the truth.
