On the night the Huixin Clan was destroyed, Shadow Master Jing Yan brought a baby girl, Yun Zhiwan, back from the ruins. Through brutal training, he forged her into a blade of the Netherworld Pavilion, while hiding an unknown tenderness between father and daughter. But Pavilion Master Shi Shibao's "Life-Obscuring Powder" altered her memories and sent her to Lingxi Cave Heaven, where she became a sword aimed at its master, Ling Chen.
A deception in the name of love and an assassination that pierced her heart tore her apart between hatred and true affection. When the truth behind her clan's destruction emerged, the Shadow Master gave his life to atone. She became a demon to exact revenge, but after achieving it, she was trapped in an abyss of guilt over Ling Chen.
Amnesia was her final disguise, and silence was his unspoken protection. Once they crossed blades, now they keep quietly to their own corner. But can the wounds carved into their very bones truly be healed by time?
