In 1638 AD, the Ming Dynasty was in turmoil due to internal and external troubles. The Liaodong cavalry trampled through the mountains and rivers, and the Central Plains bandits swept across the prefectures and counties. In this era of blood and fire, three young people with very different backgrounds were forced to be involved in the torrent of war - a scholar who abandoned literature and turned to martial arts, a Jurchen warrior who bore a blood feud, and a refugee girl who struggled to survive. They each fight for faith, revenge and survival, but they meet and fight under the pull of fate. When the sunset of the dynasty dyes the sky red, who can keep the last glory of humanity in purgatory? This is an epic masterpiece about war and human nature, recreating the magnificent, cruel and dark historical picture of the late Ming and early Qing dynasties.
