Xuanyetai: Luoyang Ghost Market Volume continues the old case of the demon lanterns in Chang'an. Pei Zhao, Liu Lingyue, and Yan Qi arrive in the divine capital of Luoyang to investigate the Twelve Ghost Covenants, which trade in lifespan, appearance, voice, name, and even blood ties as the price. As the investigation deepens, they discover that what the ghost market truly trades is not desire, but the relationship between human beings and the real world. When the entire city of Luoyang might be written into the covenants, the three of them must draw the final boundary between 'voluntary' and 'price', able to decide for themselves, but unable to sign on behalf of others.
