Shen Zhen was seized and taken to the palace by the Ninth Prince, Li Jin. As they tormented each other, they gradually fell in love. Unwilling to admit her feelings for Li Jin, Shen Zhen took the alias Huang Shizhen and joined the Phoenix Clan in order to escape.
Huang Liuchen, chief of the Phoenix Clan's Sixth Tribe, suffered from dissociative identity disorder. Two souls lived inside his body: Chi and Mo. When Huang Liuchen was calm, Chi was in control; when his emotions stirred, Mo would appear. As a result, Chi could never experience romantic love. Whenever he fell for someone, Mo would emerge. After Chi was moved by Shen Zhen several times, Mo gradually fell in love with her. Chi would never know that he had ever felt anything for Shen Zhen. Deeply lonely and incapable of feeling love, all he wanted was a child to keep him company in his old age. So he repeatedly tried to bring Shen Zhen and Mo together, hoping Mo would have a child with her. But Mo did not want Shen Zhen to learn of his feelings, because he had already decided to leave. He wanted Chi to experience a complete life.
Later, Shen Zhen and Li Jin fell into a misunderstanding. When she learned the truth, she went after him, only to find the court in turmoil: Zhu Yan had taken the emperor hostage to command the nobles. Li Jin had no choice but to give up his dream of living a quiet life as Shen Zhen's husband. After sleeping with her, he deliberately provoked her into leaving. Mo had been searching for a cure for his condition, and eventually found one, then tricked Shen Zhen into treating him. Shen Zhen later went to Fengming City and gave birth to her and Li Jin's child, and became engaged to Huang Liuchen. But Mo had no intention of marrying her. Instead, he went to bring Li Jin back to her. Li Jin appeared on their wedding day, and Chi was deeply shaken, but Mo did not appear. Only then did Chi learn that Mo was dead. Shen Zhen would never know that she had killed Mo, who loved her deeply, with her own hands. She would never even know Mo had existed.
