Shen Zhen was taken into the palace by the ninth prince Li Jin. During the mutual torture with Li Jin, the two fell in love with each other. Shen Zhen did not want to admit her feelings for Li Jin, so in order to escape, she changed her name to Huang Shizhen and joined the Phoenix clan.
Huang Liuchen, the leader of the six tribes of the Phoenix tribe, suffers from dual soul syndrome (dual personality). There are two souls living in his body. One is called Chi and the other is called Mo. When Huang Liuchen's mood is stable, he will be red, and when his mood fluctuates, Mo will appear. Therefore, Chi can never feel love. Once he is tempted, Mo will appear. Under Chi's heartbeat many times, Mo gradually fell in love with Shen Zhen. Chi never knew that he had a crush on Shen Zhen. He was very lonely inside. Because he couldn't feel love, he only wanted a child to accompany him until he grew old. So he brought Shen Zhen and Mo together many times, hoping that Mo and Shen Zhen would give him a child. However, Mo did not want Shen Zhen to know his love because he had already planned to leave. He wanted Chi to experience a complete life.
Shen Zhen later had a misunderstanding with Li Jin, and later learned the truth and followed him. Unexpectedly, the court encountered changes, and Zhu Yan coerced the emperor to order the princes. Li Jin had to give up the idea of being an ordinary couple with Shen Zhen. After having sex with Shen Zhen, he deliberately provoked her to leave. Mo has been looking for a cure for the disease, and then he finally found a cure and tricked Shen Zhen into treating him. Later, Shen Zhen went to Fengming City to give birth to her and Li Jin's child, and made a marriage contract with Huang Liuchen. However, Mo did not intend to marry her at all, but went to find Li Jin for her. On the day of the wedding, Li Jin showed up. Chi Da was stimulated, but Mo did not show up. Only then did he know that Mo was dead. And Shen Zhen never knew that she had killed Mo, who loved her deeply, or even knew that Mo existed.
