This chapter for me seems very ok-ish chapter.
Luffy's Dream:
-I think Oda is dragging this thing by not telling us what exactly Luffy wants. He told Kaido that he wanna make a world where everyone can eat. And now we hearing he has some other aspirations which made Shanks bet on new age.
Comeon just show us what it is.
Zoro's position:
-This one i feel is kinda stupid that Zoro is stopping SHs declaring war on Mariejois. We know Luffy at one point is gonna do that. I thought it will be bcus of Boa. But I guess it might be bcus of Sabo or Vivi. Yet we not going towards Mariejois bcus we still need to find Vegapunk's Lab
Sabo knows Im:
-So it seems Sabo saw Im n knows that OPverse has 1 authority whose greater than CDs or Elders. Prolly why Im signed death warrant of Sabo n blew that island.
This is interesting as it seems Im has one of the Ancient weapons. Also it was lyk Skypiea which Enel used. That brings the question was Enel correct when he said he was a God? I mean he could be a Celestial Dragon who went to Skypiea to rule over them lyk Im does.
I will rate it 4/5.
Sabo would have activated Logia intagibility. He also got flight ability so he might have escaped the blast radius.
Sabo now knows that the world is ruled by Im and they got one of the ancient weapons.
That being said why did Im only used it on Lulusia island. Why not on Kambakka where revs are stationed or WCi or Wano or Beehive. They could have easily ended Yonko / Revs hagemony in NW.
I have this feeling that the weapon might not be that gud against Df users or Haki users and it is still in experiment phase. He prolly used it first time to figure out how that weapon works.
