From what I understand (but I am really just guessing, don't take my words as the pure truth) this seems to be a little extra chapter that shows what happened between Kay getting pregnant and him and ML becoming the Emperor and Empress. ML and the wizard are just getting rid of all the zombies that they've found in that place where they have found the first fower of Alosha. ML wants to find another flower (since one already grew there, why not two?) because he doesn't actually want to become emperor. The fact is that a second flower was there but got another person pregnant, that then became a zombie. While purging the area from zombies, they find this last zombie and while trying purifying/unaliving it, the zombie releases from its body a baby that actually kept growing in it even if the body of the 'mother' was evil aka a zombie. The wizards take the child with them because the baby has the potential to become a wizard themself, and at the same time ML decides to become an emperor because this will keep Kay at his side (as we saw it, not really lol Kay will try to flee before the wedding). I don't know what prompted the ML to want to become emperor AFTER he saw the child. Maybe because he has seen that children birthed thanks to the flower of Alosha can survive basically anything? I don't know.
This is all my guess ofc.
I came here to say that this title is having a sequel in Korea right now, 11 years after the first volume was published. But I am surprised that the scanlation is not completed. The official version is already all out
