Li Susu knew that she could not let go of her feelings therefore she won't be able to practice the loveless cultivation. She told her adoptive father Qu Xuanzi about this. Qu Xuanzi only hoped that his daughter would be safe and happy, even if she chose the wrong person, he would be by Li Susu's side. Qu Xuanzi promised that he would find a way to help her control the evil bone, but this was accidentally heard by Di Mian. Therefore, Di Mian suspected that Cang Jiumin approached Li Susu in order to get back the evil bone, although Li Susu explained that she trusted Cang Jiumin, Dimian had his own plan in mind.
Erbai Yu received Si Ying's order to threaten him with the lives of his clansmen to bring the magic fetus back to the abyss. Qu Xuanzi discussed with Di Mian to set up an array for Li Susu to remove the danger of evil bones. Di Mian heard that his daughter Li Susu was going to marry Cang Jiumin, and proposed to suppress the evil bone power for Li Susu on the grounds that Li Susu and Cang Jiumin could live together without any worries. Di Mian gave Li Susu a lava stone tiger carved in the abyss, and Li Susu was very happy to receive the gift from her biological father.
Li Susu told Cang Jiumin that her father had a way to suppress the evil bones, and that he would set up an array to cast spells for three days. Cang Jiumin promised that when Li Susu gone, he would make all the plans and to pick her up with a dowry gift. Zhao You thanked Qu Xuanzi for protecting his apprentice, Cang Jiumin. Although Cang Jiumin was a devil's fetus, he had vaguely shown a god image when he refined the Huxinlin, which proved that his Taoist heart was stable, and he would be able to protect the common people in time.
Si Ying came to see Yei Mei, and she was happy to know that the entrance of the Demon Palace could revive the demon god as soon as possible, but Yei Mei thought that no matter whether it was a god, or demon, their lifespan was only a short time, so the most important thing was to fulfill themselves. Si Ying devoted herself to the Demon God, what could the Demon God bring her, but Si Ying believed that as long as the Demon God wanted what she wanted, she would do it willingly.
Di Mian and Qu Xuanzi cast spells on Li Susu, but Li Susu still did not wake up after casting the spell. At this time, the evil bone came out of Li Susu's body, and Di Mian's true intention was revealed. He killed Qu Xuanzi with the Zhantian Sword. Only then did Qu Xuanzi realize that Di Mian's true intention was always the evil bone. And Di Mian coveted the power of the demon god, and it was for the power of the demon god that he turned to the demon god in the first place. Di Mian killed Qu Xuanzi with a sword, got the evil bone from Li Susu's body, Qu Xuanzi stabbed Di Mian with his last breath, and finally died beside his adopted daughter Li Susu.
Erbai Yu had a drink with Cang Jiumin on the grounds that he wanted to leave, and took the opportunity to knock him unconscious and bring him to the gates of the Demon Realm. Cang Jiumin knew that he could not forcefully leave this matter, so he could only follow Si Ying and Jing Mie's thoughts for the time being. Cang Jiumin opened the prohibition of the gate of the Demon Realm and successfully entered the Demon Realm. Here Cang Jiumin saw the phantom of the Demon God who looked exactly like him, and knew that sin is the responsibility of the Demon God. God is the light of the world, and the Demon God is this Shadows of the world. The demon god couldn't get out of this demon realm, and one day he suddenly wanted to do the opposite, wanting that there would be no clarity in this world. In order to create a peaceful world without joy and sorrow, he created the path of compassion. When there is no distinction between pure and turbid qi in this world, there will be no sin karma. When he succeeds, the Three Realms will return to the chaos where the demon gods were born, and he will be free.
After Li Susu woke up, she learned from Yue Ya that Cang Jiumin killed Qu Xuanzi, seriously injured Di Mian, and took away Xie Gu. Li Susu didn't want to believe this, she cried bitterly after seeing the body of her adopted father Qu Xuanzi. Knowing that all the immortal sects united to surround and kill Cang Jiumin, she still believed in Cang Jiumin, and hoped that Gongye Jiwu would give Cang Jiumin a chance to explain. Gongye Jiwu put Li Susu under house arrest as the head of the Hengyang Sect, and he didn't want Li Susu to intervene in this matter again.
When Cang Jiumin woke up, he found himself imprisoned in the Demon Realm. He saw tErbai Yu who came to deliver food, and learned that Si Ying and Jing Mie had found the Yiyue Clan five hundred years ago to force them to find the magic fetus, and forced Erbai Yu to serve them. Now only when Cang Jiumin becomes a Demon God can the Yiyue Clan regain their freedom, Erbai Yu begged Cang Jiumin to become a Demon God for these people. Cang Jiumin understands Erbai Yu's feeligs, but the countless creatures in the four continents and three realms are equally important. Si Ying heard the conversation between the two, and learned that the devil fetus was unwilling to resurrect the devil god.
Si Ying took out the yellow and red umbrella and told Cang Jiumin about her past. She and her elder sister were on the bank of Chishui. Later Tianhao, God of War of the God Realm, took them away her sister and plaved her into Huoyang Cauldron for refining. Later, the demon god killed Tianhao and rescued Si Ying, and her sister was tortured by her soul. She was thrown into the mortal world by the demon god, and her body and the yellow-red umbrella merged into one. Since then, Si Ying has always kept the kindness of the Demon God in her heart, and she has been obsessed with resurrecting the Demon God for so many years. Knowing that Cang Jiumin would not give up the idea of returning to the fairy gate, Si Ying simply told him that Jing Mie had sent the news of Cang Jiumin's return to the Demon Realm to Hengyangzong.
