Tantai Jin invited Li Susu to raise a toast to all the sins and deaths in the world. After the two drank the last glass of wine together, Tantai Jin made the magic palace reappear. Tantai Jin told Li Susu that as long as there are sins in the world - If the karma does not stop, the demon god will never die. Only when the path of compassion is shared and the world is turbid can all living beings truly return to the peace.
Li Susu thought that what the Demon God gave was a great gift, and she should return a great gift. Li Susu summoned Chong Yu, and she planned to burn Chong Yu to release her divine power, and at the same time, she started the Sacrifice Formation. Gongye Jiwu came with all the sects of the Immortal Sect, and seeing Li Susu trapping Tantai Jin with a large formation of sacrificing her life, Gongye Jiwu joined forces with everyone to start the Star Punishment Formation.
Li Susu thinks that she is too stupid, she tried to bring Tantai Jin into the light in vain, but now she brings such heavy darkness to the Three Realms. Now she will makes up for it, and tries desperately, even if she dies, there will be fellow immortals in the future. Li Susu took action to deal with Tantai Jin, and Tantai Jin saw the Star Punishment Formation opened, and led Li Susu into the Star Punishment Formation. There are ninety-nine and eighty-one thunders in the Star Punishment Formation, and it is difficult for even a demon god to retreat completely. Tantai Jin hugged Li Susu and asked Li Susu to bear the pain of the star punishment for him, but when he really saw Li Susu suffering the pain of the lightning strike, Tantai Jin showed his heartache.
Seeing that Tantai Jin had escaped the star punishment, Gongye Jiwu was not reconciled and went forward to kill Tantai Jin. Tantai Jin found that Gongye Jiwu had used the forbidden technique to absorb the power of the fairy gate, and was going to turn into a mad demon. Tantai Jin sacrificed the marrow-washing seal, and sucked away the black magic power in Gongye Jiwu's body, hoping that Gongye Jiwu would have no more evil thoughts in the future.
Tantai Jin showed the body of a demon god, now that the evil bones are separated from the body, blessing and compassion is like a war between gods and demons, all four continents and three realms are suffering. Ye Qingyu, who is far away in the world, sees the suffering of innocent people, and uses demon power to prop up a barrier for Jingguo to protect the citizens. In order to make Li Susu hate him to the bones, Tantai Jin sacrificed the god-killing crossbow and shot at the disciples of the immortal sect. Li Susu witnessed the tragedy five hundred years ago, and entered the world in her heart in grief and anger, and saw her mother Chuhuang and Twelve God, and then broke through the ruthless way and became a god.
Li Susu took Tantai Jin to the last place that was not devoured by the path of compassion. She understood that what Tantai Jin really wanted was to make her turn into a god and kill him. At the moment when Li Susu broke through the ruthless Tao and became a god, she saw every corner of the world, heard all the sounds in the world, and felt Tantai Jin's heart. Although Tantai Jin absorbed the power of the demon god, he was not controlled by the demon god. He used the posture of the demon god to force Li Susu to sever his lust and cross the tribulation and nirvana.
Li Susu never thought that her own existence was born for the death of Tantai Jin. Tantai Jin told Li Susu that his life had been hard, and he hoped that Li Susu would end it all. Tantai Jin believes that Li Susu can save all disasters and change the fate of the four continents and the three realms. The purpose of the demon god has never been to unify the three realms, but to destroy all things and return everything to chaos. Tantai Jin has already connected the Dao of Compassion with himself, so that Dao of Compassion and the Demon God will live and die at the same time.
Li Susu still had a lot to say to Tantai Jin, but she told him she will tell him when the two met again, Li Susu kissed Tantai Jin and shot him cruelly. With the death of the Demon God, the Dao of Compassion gradually disappeared. Li Susu thought that since the God of Demon was going to disappear, the world no longer needed gods, but Tantai Jin took out the Heart-protecting Lin to send Li Susu out of the Dao of Compassion. In the end, Tantai Jin crushed the bones of the evil, and was buried in the same mourning way, and the four continents and three worlds restored peace and prosperity.
Li Susu woke up in Jingguo Imperial Mausoleum, where she used her divine power to see Tantai Jin, who had become the demon god, come to Jingguo Imperial Mausoleum, put on her favorite white clothes, and engraved herself as Ye Xiwu. The tombstone also created a scene where Ye Xiwu bid farewell to Tantai Jin. Li Susu knew all the truth, and that Tantai Jin had lied to her again, and couldn't restrain herselff from crying.
After five hundred years of turmoil, the world has finally found peace, and humans, gods, and demons can coexist harmoniously. Li Susu and her daughter travel the world, and they eventually arrive at the Mo River, where Li Susu reminisces about her time with Tantai Jin and tells her daughter the love story of Princess Sangjiu of Mohe and the God of War. In the distance, Tantai Jin can be seen.
*****In the novel, Li Susu reunites with Tantai Jin, who has been reincarnated, and the three of them live happily ever after, which the series either cut off that scene or didn't go that far into the story.
