At the twilight of the Tang Dynasty, a mysterious burglary rocks the city of Chengdu, setting two powerful figures on a collision course. Long Ao Yi, the fierce leader of the Longzhu Sect, stands for the Lower Jiuliu—the working class made up of entertainers, artisans, and rogues. Opposing her is Li Qing Liu, a refined and calculating silk tycoon who leads the elite Upper Jiuliu.

What begins as a battle for control soon shifts as deeper conspiracies come to light. Forced to work together despite their clashing worlds and values, Ao Yi and Qing Liu journey from the city’s bustling alleys to distant lands and the imperial court. As they navigate intrigue in both the martial and business realms, an unlikely alliance forms—one that may decide the fate of the city itself.
