Qin's Moon: The Legend of Qin

Assassins Baifeng (White Phoenix) and Moya (Ink Crow) debate the consequences of their actions under the orders of the general they serve. Baifeng accepts a challenge by Moya to try to save a little bird being attacked by the general’s falcon without harming the falcon. Moya wins the challenge and they continue the debate their situation. As payment for losing, Moya asks Baifeng to accompany him to see the new resident of the Sparrow Pavilion. They observe a beautiful woman playing music on an invisible Guqin (sounds like a piano). Baifeng agrees that she is beautiful, but she is the property of General Ji Wuye. Baifeng spends the next few days listening to her play at a distance. Moya reveals that her name is Nong Yu. Secretly, Baifeng leaves her a Zither which she plays beautifully and many birds flock to listen, as well as Baifeng. She tells Baifeng that the music is called Birdsong in Hollow Valley. Moya reminds Baifeng that the Sparrow Pavilion and all that’s in it belong to General Ji Wuye. The next day, the general questions the staff about the appearance of the zither and the disappearance of his pet yellow oriole, caged next to the falcon. He suspects his falcon of killing the oriole and strangles it in full view of his frightened staff, and then has the staff hanged. He then gives Moya a mission.

Moya suddenly attacks Baifeng, reminding him of who they serve, and Baifeng’s ill-advised action of leaving a zither for Nong Yu in the Sparrow Pavilion. He will not kill Baifeng which means that they are now in danger, and must escape. Although Moya is a loyal assassin, he realizes that their lives are of little value, and they are prisoners of a different kind. They separate, and are immediately attacked by the general’s assassins. Baifeng heads for the Sparrow Pavilion and asks if Nong Yu will leave with him. She decides to stay for her own reasons and advises him to leave. After he leaves, Moya emerges from the shadows and confirms his suspicions that she is highly skilled assassin and has plans to kill General Ji Wuye. That night, when Nong Yu meets the general, he asks her to play the broken zither while Moya watch Baifeng from concealment. She creates soundless music from the broken Zither which the general does not hear and attracts many birds, but only crows. When he embraces her, she stabs him with a hairpin.

Nong Yu’s attempt to kill General Ji Wuye with a hairpin is unsuccessful and he demands that she reveal her employer. Instead she takes poison, but before General Ji Wuye can force an answer from her, Baifeng intervenes. He fights the general with the ailing Nong Yu in his arms until Moya attacks the general and tells Baifeng to leave with her and find the antidote. Before they can escape, the general seals the three in a room. Moya then manages to deflect 300 arrows aimed at them but is mortally wounded by an arrow from the general. He then tricks the general into firing an arrow which pierces one of the steel plates in the ceiling allowing Baifeng to escape with Nong Yu. With his last breath, Moya attacks and wounds the general. Baifeng rushes to get the antidote, but Nong Yu reveals that none exist, and she dies as the sun sets. A woman arrives, and Baifeng accuses her of ordering Nong Yu to kill General Ji Wuye, but before he can attack her, Wei Zhuang stops him, and accuses him of being the cause of her death because he was not strong enough.
