this battle is dragging out unesessarly. the aquatic invasion technically started since chapter 78 when the manta gave birth to aqua Beru/Meruem. and MC returned in what chapter 84 or something. that's what 30 to 40 chapters with so little progress made. at this point it's going to take what atleast 10 to 15 more chapters. world building and character development is good and all but at some point it does become way to much you should tone it down quite a bit.
