Honestly, it pisses me off when authors break the most basic things instead of improving them. In "Reincarnation Paradise," the item rarity system was fine — white, green, blue, etc. Logical and clear. But no, it had to be replaced with “common,” “excellent,” and some other vague nonsense. If you don’t like the color system — at least use the standard RPG rarity: common, uncommon, rare, epic, legendary. But here, what the hell is “excellent”? Is it better than “good” or worse? No logic whatsoever. Then there’s the fanfic angle. The author basically took "Reincarnation Paradise" and did some light edits: removed world danger rankings, gave no world-building, randomly changed base stats (from an average of 5 to 10), and renamed it to “Heaven of All Skies.” And of course, the MC instantly gets a cheat — time rewind with no limits. Dies? Just rewinds. No cooldowns, no debuffs, just infinite retries. By chapter 7, he’s died 777 times — and there are zero consequences. There’s also a quest system: kill 100, then 1,000, then 100,000 to gain broken skills. The very first one gives him infinite mana. Why not, right? Balance? Never heard of it. The worldbuilding? A joke. By chapter 10, it says he killed 10,000 beings in 3 days — that’s one every 28 seconds. But in the previous 2 days, he barely killed 1,000, mostly spiders in a nearby nest. Where did the other 9,000 come from? And it’s not like they were mobs — these were full-on creatures he supposedly fought and killed. The world is cardboard, the logic is dead, and the numbers are pulled from thin air. It’s honestly frustrating that there's a 2000-character limit on comments.

A cool book, not without its shortcomings, but nevertheless this does not detract from its merits. I will say here only one thing, to enjoy it you will have to wait out the first 1-2 worlds of the main character, and then the book will go normally. In general, I advise reading this book to those who like a realistic setting, because in this book the author will write exactly like that.
