Description：The story takes place in Chang'an City during the heyday of the Tang Dynasty. Bai Letian (played by Huang Xuan) was originally an important official in the court, but he was willing to be demoted to a recorder in order to collect materials for writing poems. Bizarre deaths occurred one after another in Chang'an City, and even the current emperor could not escape the fate of dying bizarrely. All this is related to a mysterious demon cat. The Japanese monk Kukai (played by Sometani Shota) originally came across the ocean to help the emperor remove the curse, but he and Bai Letian had a similar mind, and the two decided to work together to investigate the truth of the case. A poem like a complaint, "Qingping Diao", shows that the demon cat's mischief is inextricably linked to the death of the stunning Yang Guifei (played by Zhang Rongrong) thirty years ago. Tracing the diary left by Abe Nakamaro (played by Abe Hiroshi), who was once obsessed with Yang Guifei, Bai Letian and Kukai witnessed the former glory of the Tang Dynasty together, and also uncovered the hidden truth of the year.
