At first, when they arrive at Spirit world, they meet little wimp. Little wimp and Yue Ying is the same soul of Shao Bai. Yue Ying wants to absorb little wimp but was stop by the MC. So, the hate of MC to Yue Ying get deeper.
After that, Yue Ying turned into an egg when they cross the world to find the MC. Using sesame, MC thought that the egg (Yue Ying) is actually the same race as sesame as what the beast told her. It is a conspiracy so that Yue Ying can be near her again but was discovered. She told him that she no longer will talk to him and even ignore his presence. She can't stop him for stalking her anyway.
Then when they arrive in the tower, they fall in a illusion something, where you will trap in your own demon or heart-knot. MC has no demon but was actually enter into Yue Ying's. It shows that they back in the time when they are still Phoenix and then MC will marry her master, there is also all the characters they all know like the disciple of MC, even the enemies they killed in the past as they are the villain in the illusion. MC knew it is only an illusion but hard to resist. But in the end, she told Yue Ying that he is no longer the Shao Bai and she is no longer little seven. Yue Ying said that he don't want to be Yue Ying as Yue Ying is evil and only make MC angry and Shao Bai is different of YY. MC said that it was all actually her fault why YY become like this. If in the first place she explained to him about her saving the world and can be reborn, he might understand everything and won't be lonely before his death, and such. Then she told him, she is angry of him and if he ever do it again and hurt people close to her, she will personally kill him. She also told him that he is no longer her brother but they can start all over again as a stranger and show to her how sorry he is, if he is deserve of her forgiveness and earn her trust.
Now, Yue Ying tried his best to communicate with other people aside from her. She help him how to talk nicely. I hope 'til the endend, he will not be narrowminded again
