Leng Bing of Cold Fragrance Valley had a difficult past. Separated from her family amid upheaval as a child, she ended up in an assassin organization, where she became the apprentice of the female assassin Pan Mei. She also became entangled in a complicated relationship with the organization's mysterious leader.
While carrying out missions, she also experienced human kindness and befriended Zhu Shu, the daughter of a prominent martial arts family, who became a loyal childhood friend she could trust with her life.
Later, she returns to Cold Fragrance Valley and becomes sworn sisters with Wen Rou of the Wen family of Huaibei and Jun Suifeng of the Jun family of Jinling. They support one another, roam the martial world together, and grow side by side.
She also becomes caught up in a series of tangled grudges and romances with Ling Chong, her betrothed since childhood, who was born into a prominent family but has since drifted through the martial world.
These girls who have made their way in the martial world endure countless bloody storms, as well as pain and hardship, and eventually grow into influential figures in their own right.
