It's not megaversal or whatever this dude want to call it.
Why so condescending?
Cosmology is closer to universal
Universal is the baseline minimum from which every other scaling stems.
- Their original world / realm is a small world.
"Small Worlds" are either naturally occuring or artificially created Dimensions
small worlds are basically single planet/continent depending on shit floating on the void.
That is inaccurate. While small worlds can be found throughout the series, they themselves are not limited to be just "continents" (although there is one specific Star which is called "continent", then again this is not a small world but a Cultivation star.
We even have an in-universe progression of the MCs own "Small sealed world bead" which starts as just a few hundred KM in size and later develops, increases into a full dimension and - once it reaches a given size and power, establishes its own world principles, becoming a full planet, later even devouring other planets.
It then evolves into its own universe as well. So no, "Small sealed worlds" are not limited like you describe.
Which was explained further in the story. So that isn't even universal starting if you cross to the next realm.
No claim that small sealed worlds are universal in nature has been made in the first place.
Then the second realm he went is basically split into 2 world/planet. the last realm is basically outerspace or some shit.
I read it you are talking about the "Star Boundary", which is the name given to the Universe World where everything pre-Outer Universe takes place in.
It is true that everything Pre-Star Boundary takes place in one plane of existence - as is indicated in the graphic as well.
However what you - again - are not correct in is the fact that you believe the Star Boundary is split in two. The two major places which are being narratively used are the Star Boundary and the Demon Realm. In this case, the Demon Realm is its own Universe World from which the demons want to flee, as its shattering. Unlike previous realms of the series, it was made clear that its not a Small sealed world but another Universe like the Star Boundary from which they invade.
Basically physics is pretty fuck up like a lot of chinese novel where planets can be some floating Island/continents/mountains/giant elephant and turtles in outerspace having cities on their backs or shit
Yes but what does this generalisation have to do with the points being made in regards to the scaling of the cosmos of the Martial Peak Verse in particular?
Also their universe is basically cut into portions, Like central universe/deadzone/then the mountain pass/etc.... Point is think of how toriko have their universe shit cut in 7 layers representing different quadrant of a universe or db having 4 quadrant (South universe/north universe etc.)
Once again, there is an incorrect assumptions and mixing things together being present here.
As in the graphic shown, the different realms, Starfields, Zones etc. are to be found everywhere. Regardless whether within individual universes, the Territories where the Universes reside in or the other territories.
I don't call it multiversal as it ain't real multiverse.
Then you would unfortunately be wrong.
Dude even got trapped in another universe by the end of the story after entering a new cultivation level, he got the ability to explore the multiverse which where the story actually end..
I have not yet reached that part of the story however given your track record I presume this is also very inaccurate.
So yea you can say he probably tops at universal with the ability to cross to another universe by end of the story.
We have long since reached and surpassed point in the story where literal universes are refined into a small marble and thrown at each other for distractive purposes during fights even pre-EOS. This last phrase of yours once again shows to me that your memory of the MP verse may need a refreshing.
