Liuli, a girl from the south of the Yangtze River, was born shortly after her father died in battle and her mother's whereabouts are unknown. She lives with her aunt in the Xu Mansion in the south of the Yangtze River. Her aunt Lanruo is the fifth wife of the Xu Mansion. The fifth lady has a son named Shao Jie, who is simply a "devil incarnate"!
When Liuli was seventeen, her aunt Lanruo suddenly died of illness; there was no room for her in the huge Xu Mansion. Therefore, Liuli resolutely went north and embarked on the long road to find her mother! However, he accidentally strayed into the Central Plains' number one killer organization, "Blood Abyss·Shadow Pavilion".
There, she met two killers with very different personalities, the handsome but indifferent "Jade Flute Master" Nangong Luoxuan, and the cynical but vicious "Snake Whip Ghost Young Master" Murong Xuanyu.
The three of them, by chance, formed an indissoluble bond, either through joys and sorrows, or love and hatred.
