There is one thing that I am curious about, that wasn't really explained how. The skill combination, or to be more precise, the skills that "didn't exist before"/"godlike rarity in the universe". How did the planet(s) get the information or create these skills? The first few times were probable, but it's now getting to the point where the skill power levels surpass earth's current threshold/ceiling. (Guess you can argue that the ceiling is whatever the MC's power level is, as he is basically one with the world) Like the Lesser Cthulhu for example. If the creature is as rare as the skill describes. I doubt earth, the demon world, or the beast world, would have any knowledge of them. While the demon world is a "prime" world, it isn't an origin world (or whatever the type of world was called). Something as rare described in the skill, only knowledge from something that existed alongside them coming into the universe would know about it. Now, even if people have found one, I highly (99.999...%) doubt that it would have been alive. So while they could gleam some information from the corpse, it shouldn't be as detailed as it is in the skill/skill tree (the specific abilities gained and what know.) Like for example, the portals of terror. Even if we are to assume someone survived and encounter. How would they know where in the universe the portals lead to? Sorry for going off on a rant. I love the story and its amazing. I just feel like things are getting introduced that no parties currently involved (exclusion of the celestial grandmaster) would have knowledge of. To me, it's just screaming "my OP plot armor isn't holding up, let's throw something else at it, and make it one of a kind treasure or something." Like, the MC is basically are void level, but the demon world, a prime world, had what? 1 or 2 ranks below as it's most powerful lifeforms? Idk, just think that the skills the MC are getting, are outside the scope of what the three worlds could do, come up with, or even have knowledge of. Okay, ranting over for real. Thank you for the chapters.
