What happens to WWX's Soul during those 13 years?
I am a bit lost when I think about WWX's age. Is he 36 like Lan Wangji, or 23 like when he died? Mo Xuanyu's body is 26-28, to add into the mix. Was WWX's soul sentient/conscious in those 13 years? Could it go through any kind of reflection while not anchored? Was it an intact soul already in the beginning after his death? Why was LWJ not able to find any of it in the Burial Mounds?
To me it feels like that WWX in his second life reflects to his earlier life with an ounce of wisdom and keeping a bit of sanitary distance to it. He does not come off as freshly traumatized. It feels like he digested all what had happened to him in some way. But how was it possible for him?
