It kinda turned to crap after the issues with the other clan concluded. Maybe a bit before that even.
I read most, if not all of these types of manga/manhua/manhwa whatever you wanna call it and this often happens. Good initial momentum that gets lost after the first plot line or conflict is resolved.
Not to mention many of these drag on for 100-200+ chapters seemingly made to be produced forever without any "end" in sight.
It honestly would not surprise me if after the grand plot of the empires fall concludes they move onto saving the world from long sealed away demonic forces or go to a "higher" heavenly realm where the same crap goes on but the "power levels" are reset.
The only one that I liked after hundreds of chapters was
[Spirit Blade Mountain] as of right now 360+ chapters have been translated and overall story didn't fall in quality at all in my opinion.
You can find a great number of chapters here on Mangadex and the rest on the scanlators site. I seriously recommend it if you enjoy these types of manga.
