I read in a spoiler she gets taken away (what chapter?) and she's gone for most of the story. Is that true? How much does this act like a downer for this novel?
As far as I know she gets taken away twice which is once by her sister from the Fire Worship Sect in the Dao Saint Land and then again by her past life fiancé the from the God realm. And from what I understand by reading from spoilers her clan is a mid to high tier God clan. So I'm guessing probable God-king or God-Sovereign level.
From what I got from spoilers on latest raws MC is still increasing his strength to rescue her and so far he is low rank God-King but he still has a time limit of 1000 years before Ke'er is forced to marry the fiancé due to her father being in seclusion.
