This book is rated too highly for its content. Well, I know the high reviews are attributed to the book not being premium and the low number of reviews itself. But I usually rate books by their writing quality, setting, plot and characters and not by updating stability, being premium or whatever.
Solely based on its content, as I compare it to other works, it would be a 4.3 on webnovel, maybe a 3.9 on novelupdates for the 50 chapters I've read.
Writing quality is alright at best. Grammar mistakes are prevalent like in every other webnovel except for an elite few. Spelling is good, but punctuation and word choice is terrible. Throughout the story, many words are redundant and repeating. Because of the subpar writing quality, the story doesn't flow that well.
Story development is cliche... family problems, sick sibling, and an evil, greedy uncle ... you know it. MC got an overpowered system and will slap their faces in due time and save his family from debt yada yada. This plot is just overused. Basically, the only difference is the system and world background. One other thing... logical errors! Some things just don't make sense!
Character design also ... bland as ever, but not as bland as other novels. Main character is honestly a dumbass, one large decision he made is absolutely retarded (he could get out of his predicament easily but chooses not to because of pride) Others are logical and i can follow his thinking... Antagonists are blockheads at best, side characters don't have colour to them...
Lastly, world background, which is somewhat unique. Alright, even though it's similar to solo levelling's dungeons but called fortresses here, and similar to the thousands of other system novels and apocalyptic novels, it's somewhat unique in the sense that it's a mix of all of them. And that's... what I'm here for, because I'm a sucker for each one of these genre, not to mention having all of them in this novel
