Nine Songs of the Moving Heavens (Chinese: 天行九歌; pinyin: tiān xíng jiǔ gē), is a CG Chinese animated TV series that was released on March 10, 2016, directed by Robin Shen. It can also be translated as Nine Songs of the Sky. This is the prequel to The Legend of Qin, which takes place before the time of the Qin Dynasty. Although the two animations have intersections of characters and their timelines, Nine Songs of the Moving Heavens is an independent story
Facing the threat of the Qin State, danger seems to lurk within the Han State, which is known as the weakest out of the Seven States. Unknown to the Han Emperor, that very threat is the Great General of Han, Ji Wuye. Working under the Great General are the Four Fearful Warriors of Nightfall (Chinese: 夜幕四凶将; pinyin: yèmù sì xiōng jiāng). Each four specialized in military, finance, politics, and espionage.
In hopes of creating a new Han State, Quicksand (流沙) was formed by Han Fei, the ninth prince of the Han. With Wei Zhuang, Zhang Liang, Zinü, and Nong Yu, they support the Prince in realizing the goal of Quicksand while being drawn into a whirlpool of power named “world”.
