Well this chapter had some points that are worth mentioning.

With how dangerous the book is to those attempting to effect it in any way makes Igneel's warning very real, so I guess that it was only meant to be read by Natsu and no one else, that is what is likely to truly awaken END. That makes perfect sense. I wonder if Lucy will be possessed by the demon inside Natsu, if it comes to that point and if there is enough time. Then it might be like Kaguya where it ends up as the final villain instead of Zeref or Acnologia.

Speaking of which, Acnologia is currently crushing Jellal, which relates back to Hiro's interview which one of his cast mentioned could someone had died, if this is true, could Jellal be the one to die?

Now onto Zeref and Natsu's fight, well it is to be expected that Natsu would become stronger with the power of feelings, not only that by his flames of emotion makes him stronger as well. And to be fair on Zeref's part, all he got was Infinite Magic, it is not like he can instantly augment his spell's or physical effectiveness in battle.

So this was an alright chapter
