She is Nangong Moliang, the eldest daughter of the Su family who was once bullied. Her mother passed away with regret, and her life in the Su family was dark. Fortunately, her uncle rescued her and she found a ray of warmth in the Nangong family.
She thought she had met her true love Zheng Jinxuan, but she was betrayed and murdered. Her best friend Zhou Nianwei died trying to save her. She became frustrated overnight and decided to join the residual killer organization. With her superb forensic skills and ruthless style, she transformed into the feared "Queen of Forensic Killers" Manzhu Shahua. She fought side by side with her partner Ji and became famous in the killer world.
The gears of fate turned again. Due to her uncle's arrangement, she returned to China to take over the family business. Her dual identities as a female business president and a ruthless killer were perfectly integrated in her. At the Su family banquet, she met Feng Yechen, the head of the Shangjie killer organization, "Yehao". Her initial vigilance and the confrontation in the business field quietly gave birth to a different kind of love. The road to revenge is long. She digs deep into the conspiracy of Zheng Zhenxuan and Shen Xixue. Feng Yechen silently accompanies her, and the two become each other's most solid support.
While investigating his mother's past, the mystery of his life experience came to light. His biological father was actually Murong Linyuan, the head of the Murong family. His amnesia forced him to separate from his mother. After father and daughter recognized each other, they worked together to put down the family's civil strife. Under Feng Yechen's affectionate protection, she put aside her hatred, destroyed the Su family, got married to Feng Yechen, and had a son.
In the end, she decided to quit the world of killers and run the family business together with Feng Yechen, and the friendship and family ties they once had became even deeper. Coming from the darkness, wandering between revenge and redemption, Nangong Moliang's life is full of love and hatred, but he also finds warmth and new life in love and trust.
