I think I stopped on chapter 1418 The Fused King, 'twas a suprisingly boring arc. This novels reminds me of ISSH, one arc interesting, one boring and repeat.
Spoiler "Conditions fulfilled. The female lead just gave the green light for the Harem Route. There were a couple of nukes involved. Now the would-be harem king just needs to wake up."
So there are chapters about "romance", that is one seriously pathetic aspect of this novel. Didn't author's wife forbid him from harem which is why "romance" was forgotten?
She saw the amount of comments on it and decided money was more important I guess. Or author decided his "artistic vision" was more important than someone else's preferences. Doubt he's that respectable tho
If it is any consolation, the latest chapter in multiple ways finally touches upon the origin of the world within the story.
