So it's basically dragon hunting, and each of the dragons are hyped up to be as powerful as Acnologia. Sounds like more power inflation, but considering it's Fairy Tail, I wouldn't be surprised if the dragons simply don't live up to that hype.

I read it long ago but I stopped catching up since a while ~ imo it's not as bad of a series as many picture it

The story telling isn't compelling, and the fanservice is gratuitous.

Then wait till you see Aldoron

If you can survive Wano arc's deadly combo of shitty cover story, Nine Red Scrubbards, Oden Piece and Luffy vs Fodders, then you can definitely survive Fairy Tail 100 Years Quest.

I don't know how Fairy Tail 100 Years Quest is (I only saw a few feats from the new dragons) but Fairy Tail itself is incredibly shitty, at least after the timeskip. I'd rather watch a 10h version of Big Meme shouting "WeDdInG cAkE!!!" instead of that. And yes, I tried re-reading Fairy Tail but after the timeskip it was unbearable.
