@Twinky this ia very valid argument . the author is just dragging to increase more chapters... like the fights from the 1floor was shown again with a bit twist but the fights continued for 2-3 chapters . we do not have much chapters left to read . and the story isnt even going anywhere . as he is on the 60th floor and the progress is shown from the 1st floor . the story just seems to be stuck at one point and the whole manhua is about the detailing how he got there and what powers he has obtained
