Li Susu came to the Demon Palace to question why Tantai Jin chose to become a demon god. Tantai Jin said that because he hated Li Susu because she betrayed him on the day of their wedding five hundred years ago, and plus he searched for her in the Nether River for five years. For a hundred years, his skin was corroded every day, but at that time Li Susu didn't care about world affairs in Tianchi. Tantai Jin stated that all that was unfair to him. Li Susu once said that Tantai Jin was born as a demon god, and there is always more hatred than love.
Li Susu thought that Tantai Jin was lying, but Tantai Jin did not admit it. The former demon god bewitched him to kill Li Susu, stating flashbacks of all his relatives, friends, and masters that die tragically. The demon god said that the world has never truly loved Tantai Jin, only misery is the eternal destination. Tantai Jin shook off the demon god and realized he was in power of himself. Tantai Jin said that he always believed that his father and mother loved him; Lan An and others took care of him when he was young, his master rescued him from the weak water carefully taught him, and most importantly, Li Susu taught him how to love and loved him. He has always looked at himself in pity, and the person who wants to destroy everything is the former demon god and not him.
The former demon god attempted to take over Tantai Jin, but Tantai Jin refused to become a demon god. Instead, Tantai Jin had already experienced the three lives of man, god, and demon, and was not bound by past karma like the former demon god. As a result, Tantai Jin regained control of his consciousness and became the only demon god.
Tantai Jin, who has become a real demon god, knows that only a true god can destroy the demon god, and then understands that the only way out is to let Li Susu use the Phoenix clan to practice the ruthless way to become a god, herself, so that the demon god can be completely wiped out by her. Tantai Jin asked the demons to tell Sizhou that he would marry Fairy Yuling of Changze Mountain as his wife in three days. Gongye Jiwu wanted to kill Tantai Jin, so he decided to use Feng Yaoya's sealing power to deal with Tantai Jin regardless of his master's earnest teachings. Even if he got mad and fell into the devil way, he would die together with Tantai Jin. Gongye Jiwu came to Pang Yizhi's phantom for help on how to deal with the demon god, and Pang Yizhi handed over the Star Punishment Formation to Gongye Jiwu.
Tantai Jin once promised Erbai Yu to rescue the Yiyue clan, and on the eve of his wedding, he used the power of the demon god to break the seal of the Yiyue clan. Li Susu woke up and knew that she would become the wife of the Demon God tomorrow, and she did not want to marry the treacherous demon. Tantai Jin thinks that Li Susu will not be free from now on, and brings her to Mohe. Tantai Jin thinks that the love between Ming Ye and Sang Jiu is so insignificant under the great war between gods and demons. Who remembers this love. But he is different from Ming Ye, he will climb to the top, and Li Susu will also be by his side. But Li Susu thinks that people like Tantai Jin are not worthy of evaluating Ming Ye's feelings. After all, Ming Ye is worthy of the world and the common people.
Tantai Jin created the Ye Mansion, the prosperous capital five hundred years ago. This is also the Prajna Floating Life dream he created for himself. He took Li Susu into his own Prajna Floating Life, where she saw her once kind elder brother Ye Zeyu, her younger brother Ye Qingyu, loving grandmother and father. Tantai Jin is only Ye Xiwu's husband-in-law here, and there are also fond memories of the two of them. Ye Xiwu once taught Tantai Jin how to draw life talismans, hoping that he would become a person with no evil intentions.
Li Susu asked Tantai Jin if they could turn back, but it was too late. Li Susu bid farewell to Tantai Jin, imitating Sang Jiu and Ming Ye. Later, they consummated their wedding night in the bridal chamber.
Tantai Jin wants to open the magic gate on his wedding day, and Gongye Jiwu plans to open the Star Punishment Formation together with the disciples of the immortal gate. Tantai Jin brought Li Susu out of Prajna Floating Life, and the two went to Demon Realm to hold a wedding ceremony.
