Tantai Jin witnessed his mother, Yue Ruanruan, marrying Tantai Jinwuji for the sake of the clan. At first, the couple loved and lived in harmony, and Yue Ruanruan became pregnant. However, the child was difficult to deliver, and Yue Ruanruan asked to keep the child before she died, but she died of dystocia in the end. Tantai Wuji hated Tantai Jin for taking away his favorite woman, and it was because Yue Ruanruan's maid pleaded that Tantai Wuji kept Tantai Jin's life, but also allowed her maid Yingxin and Lan An to take Tantai Wuji with her. Taijin fends for itself in the palace.
Tantai Wuji hated the existence of Tantai Jin, and abandoned the name he had prepared for the child in advance, and only gave him the cursed name Jin. Meng Yao found someone who was awake and took Tantai Jin away. Mengyao found that Tantai Jin couldn't fall asleep because he had no emotions, so he couldn't feel the seven emotions and six desires. But Meng Yao found a trace of weakness in Tantai Jin from the dream just now, and this weakness can also make it fall asleep for the flower of nightmare to bloom.
Li Susu, who fell into a dream, saw Lan An and Yingxin find Tantai Jin, and in order to take care of Tantai Jin's growth, the two lived aggrievedly in the deep palace. And Tantai Jin who is growing up is also being bullied. In order to let them live, Lan An is going to sneak out of the palace to seek help from the Yiyue clan. She asks Yingxin to take good care of Tantai Jin. But then Tantai Jin was taken as a hostage and sent to Shengguo, and Yingxin also thought that Lan An had betrayed her and escaped from the deep palace alone.
Li Susu followed the young Tantai Jin to the Sheng Kingdom, and saw him being bullied and beaten by the children of the Sheng Kingdom. In the end, it was Xiao Lin who was the Sixth Highness who appeared to save him. Seeing that Xiao Lin is loved by his parents, the young Tantai Jin is full of envy. He imitates Xiao Lin's words and deeds, just to be liked by others. Later, seeing that Xiao Lin liked Ye Bingshang and cared about Ye Bingshang, Tantai Jin also secretly followed suit, so he was misunderstood to like Ye Bingshang. But Tantai Jin, who was tortured by various beatings, finally found that the world didn't like him, even Yingxin, the maid who took care of him when he grew up, didn't like him. In the end, he was discouraged, thinking that it was not easy for him to live, how could he expect others to like him.
Li Susu saw that Yue Yingxin had received a letter from Tantai Minglang, in which Tantai Minglang asked Yingxin to kill Tantai Jin. In order to leave Sheng Palace and return to her hometown, Yingxin finally chose to betray Tantai Jin. Li Susu saw that Yingxin's dream was over, and she also woke up from the dream. Xiao Lin brought Pang Yizhi to Banzhen Mountain, and Pang Yizhi managed to lure Meng Yao out, hoping to take the opportunity to rescue everyone.
Li Susu woke up and found that Tantai Jin had fallen into a dream. In the dream, Tantai Jin found that his parents loved and cared for him very much. They not only sent him to Xiaoyaozong to practice, but also married him with the daughter of General Ye of Shengguo. Originally thought the bride was Ye Bingshang, but Tantai Jin found out that the bride who was finally sent would be Ye Xiwu, her dream was shattered. Then Tantai Jin once again saw his mother starving to death because of her dystocia, and her father hated him for wanting to kill him, Lan An, Ying Xin, Xiao Lin abandoned him one after another, and even Xiao Lin even tempted him to put an end to all the tragedies and sufferings . Suffering so much, Tantai Jin wanted to commit suicide to end everything, but Li Susu came to stop him. Also because of Li Susu's obstruction, the two woke up from their dreams.
Xiao Lin and Pang Yizhi teamed up to deal with Meng Yao, but Meng Yao was no match for the two because of the weakening of the demon power, so he had to take the opportunity to escape back to the mountains. The dream demon who returned to the mountain found that Tantai Jin had destroyed the vines, and wanted to devour Tantai Jin in anger. But the voice in Tantai Jin's heart told him that Tantai Jin's own blood could restrain the monsters in the world, and his body should be able to carry the monster power. Induced by this words, Tantai Jin began to absorb the power of the dream monster.
Xiao Lin and Pang Yizhi rushed to Banzhen Mountain to rescue everyone. After being rescued, Li Susu woke up in the mansion. Thinking of Tantai Jin's miserable life in her dream, she wanted to give Tantai Jin a hand, hoping that this would make Tantai Jin feel better. Tai Jin no longer becomes a Demon God. Tantai Jin woke up from the dream, and found that he could use demon power, and he also fully understood the feeling of power.
