During the Northern Song Dynasty.
There is a martial arts family living in the outskirts of Bianliang. There is a golden whip hidden in the house. Whoever possesses this thing is equal to the world. Many people in the world and those who love weapons want to get the golden whip. Corrupt officials Pang Wen and Pan Gui team up to steal the golden whip.
Late one night, a group of men in black besieged Huyan's home to seize the golden whip. More than a dozen members of Huyan's family were killed. Huyan fled with his wife and children, but they were separated on the way. Unexpectedly, his wife was snatched away by the thieves, and several brothers and sisters were separated during the flight. Cai Luan fell into the hands of a man in black and was rescued by a passing Mu Xiannv. In order to avoid Pang Wen's pursuit, Mu Xiannv sent Cai Luan to Yuntai Mountain overnight to become a disciple of an expert.
Ten years later, when the descendants of Hero Hu Yan grew up, Cai Luan determined to take revenge and regain the golden whip.
