Comments of chapter undefined of Breeding Dragons From Today

TLDR: Author slows down the story and is dragging out the arc. So, I have read until the latest available chapter at the moment 676, well skimmed the latter ones more so then reading. And I had to come back to warn future readers in what I believe to be a major change in the novel. Which would be how much slower it has gotten I mean things are just being dragged out for several chapters and I really do believe that the author has been replaced. Slight spoilers we get a R-Rated (18+) scene for a side character and that was well not the greatest thing to imagine, and there is girl introduced who the author or maybe translator refers to as a legal loli. And if you have read to this point you would know that neither of these have occurred before. Now I can understand if the author needs time and worldbuilding to develop future plans or even figure out where they want to go, but the entire underworld arc has been such a letdown. Especially since its been like 200 chapters of slow progression in terms of power and plot, not so much for worldbuilding or side character stories.
