Also known under the title Wushuang, this danmei/Boys' Love novel series originally released in Chinese–and coming to the English language for the first time–is set in the universe of the author's other popular novel and animated series Thousand Autumns: Qian Qiu!
In this historical wuxia tale, two rival investigators try to get to the bottom of a mystery...and their own complicated feelings.
On a snowy night, an envoy sent by the Kingdom of Khotan is ambushed on the road, massacred with his escort. Not a living soul remains, and the attackers vanish―along with a precious jade intended as tribute to the Emperor of Sui. A member of the emperor’s secret intelligence agency, the Jiejian Bureau, pursues the case: the formidable deputy chief, Feng Xiao. His investigation takes him to Liugong City, where top martial artists from across the land gather for a mysterious auction.
