Two Xia Qinyues Theory

#1

“Was she really Xia Qingyue? It was like she had a completely different soul!”
This looks to me like a hint that XQ is not her real self…
I think her body possess two souls
SO…when her glazed heart awakened…HER orignal personality got suppresed by the other soul leading to the change in her character…Therefore,she can very much be the real villain and not the real villain at the same time…This expains a lot…YC fighting her in the end…Helping her real personality win…something similar happened in an another novel

No she just XQ with a thousand years knowledge and memory after inheriting wuya’s
