Xing tried to convince the Emperor but failed and he was too tired to argue with her and ended up sleeping in her couch and Mo Chen went out for hunting and Xing showed all her frustration with many words to Bai Li who just wanted to sleep.
Xing just missed Shengli a lot that night. If he were here, he'd never stop her from what she wants to do but will find a way for her to do what she wants safely.
My Prince! You really are the man for me and I miss you a lot!
So what if she cannot have permission to leave, she'll escape here. Once she enters the mountains, who can stop her? She decided to take Bai Li with her in this adventure and he agreed too as he had promised to protect her.
Xing went to sleep peacefully with that thought in mind and she had peaceful dreams. Bai Li got her an incense with some soothing flower fragrances and that brought her the memory of the colourful garden Shengli brought her on a date one day in the capital city's Flower Festival.
