Ryn:

agreed, it would have been much better if she was the original concubine, because now im worried why is she there? will she get home? What will happen to her son?

I’m sorry I’m lost. Transmigration? Are we still talking Pursuit of Jade? Boy that went right by me…..

It was only last minute addition, last couple chapter that QQ tell FCY, she came from a very far place needs thousand years. In my opinion, even she not talk it, it won't change overall storyline

Got it! Thanks!
