I had to check so many times if the chapters were numbered wrong because it's jarring how big of a jump chapter 109 is from 108 (end of season 3). Like the others said, it's rushed from floor 60 to 90. What happened in between was summarised in a few panels. I don't know if that's what happened in the novel too (idek if there's one) or they just want to shorten and progress fast with the story, but they could've made the transition better ┑(￣Д ￣)┍
