The autumn hunt beneath the Tang Dynasty sky brings together warriors, nobles, and ambitious schemers for a grand competition of archery and horsemanship. When an assassination attempt on the Empress unfolds during the festivities, suspicion falls on an unexpected guest: Murong Ji, the young Khan of Tuyuhun, whose presence at court already walks a fragile political line. Desperate to clear his name and prevent a diplomatic catastrophe, Murong Ji turns to Pei Kun and his circle of trusted investigators. What begins as a simple murder inquiry spirals into something far darker, pulling together a ragtag team of warriors, strategists, and skilled fighters who must untangle court intrigue, hidden agendas, and genuine danger. The stakes climb higher than personal vindication: one wrong move could ignite conflict between kingdoms and shatter the fragile peace. This is period mystery wrapped in sword-clashing action, where friendship and loyalty become tools as sharp as any blade. Expect sharp dialogue, genuine camaraderie between characters, and the constant threat that nothing in court politics is ever as simple as it appears.
