As someone who read the whole novel, I'll give out 4.8 stars.
The Writing Quality is perfect. Well, I can't say much on it as someone who doesn't naturally speak english, but it was perfectly understandable for me. And even if there were errors and misspellings, they were quickly corrected as soon as possible.
Story Development? That one deserves some praise-worthy claps! Wuxia? Xianxia? The search of Immortality? Dao? The understanding of medicine? Get that stuff outta here! This novel makes a twist out of everything that would be considered cliches! Immortality is actually achievable, the dao can be actually understood! The elements of the beginning matter even in the end, and the elements of the end explains everything about the beginning! Everything makes sense once you read the whole novel, and you will not regret it, I can assure you that. So, before reading the novel, don't assume that what you know from the other cultivation novels will help you here, because you will be as lost as an American in a vegetarian bar.
Character Design... Well, it's excellent! Our protagonist, Gravis, goes all the way through the emotional spectrum, starting as a naive kid before trying to harden himself to prepare for the world of cultivation, before he actually matures. Everyone makes mistakes, and Gravis is no exception, but it's because of the mistakes he makes that he grows up after understanding and learning how to deal with them.
You will rarely see a protagonist with a personality as excellent as Gravis among the novels here in Webnovel, in my opinion. However, while I want to assign 5 stars here like in the rest, I have to take off a point because that's as far as it goes for Gravis. As for the side characters, I have to admit that they all were written with a plan in mind, the author knew what to write for each of them and perfectly shaped them as he wanted. However, to be honest, I think the author could have done more with them, but it's fine as long as the novel is good, which it is.
Updating Stability? Well, it was 2 chapters a day like the majority of the novels here, what else can I say? Except at the end, when the author had to send out 1 chapter every 2 days due to some deals with WN itself for a certain in-app event, the author respected his timeline.
World Background? Absolutely outstanding! This cultivation world can truly be called unique, and you can't tell me otherwise without reading the novel first! We have all the tools to understand the whole world, along with some details that gives us a clear sight of how the world looks like. As for everything else in the sidelines? That's open for interpretation. But they are on the sidelines because they don't truly matter, you can consider them at most as filler.
All in all, I truly appreciate the time I spent with the novel and the author. I enjoyed reading about Gravis' journey across all the four worlds, and seeing the ups and downs of his adventures.
Whether it was when Gravis was heavily injured because of unique circumstances, whether that happened during a hard fight, whether he spent his time by himself getting stronger, whether it was when he found his friends and lover, whether it was when he dealt with his father, the Opposer, and the Highest Heaven... As a reader, I can definitely say that I am satisfied with this novel, from the start to the end.
I will be reading Sword God in a World of Magic now, a novel made by the same author. For anyone reading this and actually liking the novel, I'll be waiting for you in there. Goodbye, Gravis and everyone, it was a pleasure to read about your story.
