On the same day Murong Yun Su’s father dies, her betrothed ends their betrothal. Her cousin, an illegitimate prince, returns to Murong Courtyard House and offers to marry her. She rebuffs her cousin’s offer and accepts the marriage offer from Chu Zhang Ca, leader of Mo Jiao Cult. Under Mo Jiao Cult’s protection, her former betrothed’s sect, and the emperor’s army don’t dare to attack Murong Sect overtly.
In the wuxiaworld, no one can boast that they saved Mo Jiao Cult’s leader’s life except Murong Yun Su. Chu Zhang Ca has never forgotten, she grudgingly saved his life without knowing each other’s identities. He secretly stole her handkerchief and spent three years searching for his savior.
Together, Murong Yan Su and Chu Zhang Ca become the most feared black belly couple in the Quxiaworld.
