Hoo boy, so now Zeref is not only immortal but also invincible? Oh well, at least the manga is now picking up the pace.

I predict one of three things will happen: -Lucy will rewrite some stuff in the book of E.N.D that will somehow revive Natsu -Natsu's seeds will fuse and transform his body into some sort of really powerful dragon/demon; effectively ceasing to exist as a human, making him a new threat (doubtful) -Zeref's success will be short lived because his heart isn't pure or some-such, and the power of friendship/love conquers all
