LatestElder Gray dumps the origin power into the ruined temple's well and plans to destroy Chang'an. Liu Tai Zhen and the rest suppress the sinister force of the well from the Demon City. Everyone from Changxi Palace works together to control the well but they cannot stop the sinister force from spreading.
Mei Zhuyu, a calm and reserved nobleman from a lesser branch of the Mei family, arrives in Chang'an as an official at the Bureau of Mystic Investigations. During a banquet, he meets Wu Zhen, the bold and unruly younger sister of the Empress and secret Guardian of the Demon Underworld. Both hide their true identities. Wu, a half-demon striving to keep peace, and Mei, a skilled demon slayer, seek the truth behind the fire 18 years ago. As bone demons rise and unrest grows, they fight side by side, forming a bond that deepens into love until the Changxi Palace launches a purge, forcing them to face each other's secrets and the past they share.

Trivia, insights & behind the scenes
Fu Hua specifically requested practical bone demon puppets rather than full CGI, creating the unsettling tactile quality of the horror elements.
The Bureau of Mystic Investigations draws from Tang Dynasty 司天监 (astronomical bureau) but reimagines it through xianxia tradition—celestial bureaucracy meets supernatural police state. The Changxi Palace purge mirrors historical 安史之乱 mass purges of perceived threats to imperial legitimacy.
