If Xianxian had not played Wangxian's love song at Dafan Mountain after he returned from being sacrificed...
It should follow the original plot line and try not to ruin the character. (The original work may have many sentences.)
The beginning of Chapter 7 can be said to be another idea.
It's about Lan Wangji and Wei Wuxian who experienced everything after they returned from Xianshe. It was just Lan Wangji's nightmare! However, after waking up from the dream, Lan Wangji will return to the story of the period when Wei Wuxian lived in the mass grave (starting the journey of changing his life).
It should refer to the events of the original work and have private settings. Try not to break it too much. Wangxian will never break it! According to the original work, only Wangxian is crooked!
