Can someone please give me spoilers about who is the father of rashta'child and what happe...

I have read the whole novel and again the author has not explicitly approved any theory. It's like GoT where George has left a lot for the readers to discern and speculate.

I know Duke Ergi's past and his intentions. He wanted revenge as his family was destroyed by Soveishu's father's former mistress. But whether he did manipulate the test or not is something the author gas not confirmed. He did make some off handed comments like Glorym looked like her father but we don't know what he meant by that. Added to this is the presumption that both Navier and him became infertile due to the cookies and Navier was cured by the magic bad but that too is unconfirmed. We can only speculate and theorise.

this is why i told earlier that i don't want to enlighten you anymore.
you need the author to spell everything out in red ink just for you to see the point.
i already pointed everything out and disproved your points, so idc anymore.
just read more actual books and novels to broaden your perspective about different kinds of storytelling.
I'm done, I can't really tolerate stubborn species.

I know why Duke Ergi wants the empire to be gone. I have read the novel. That's not up for debate. But did he actually manipulate with the results is in question because it's not been clearly specified by the author. He could have and Glorym could be Soveishu's daughter but it's also been hinted that both Soveishu and Navier were rendered infertile because of the cookies and Navier healed because of the magic bed.

The author has not spelled anything out that's the point. The way you're going on and on about how only your theories are correct when the author has left for us readers to speculate a number of theories is really looking idiotic. If you were in the GoT fandom you would have cried yourself to sleep because people have so many other good theories.

there's a difference between a good theory and a refuted one.
read the original novel cause they used specific words and phrases that the english translation didn't manage to catch the meaning that well.
I just remembered that this is the reason why I feel strongly about this.
again, idc about your opinion anymore

The author has never refuted or confirmed amy theory. What words are you specifically talking about? I have never heard anyone claim that there's a disparity between the Korean and the English novel.
