Defiance of the Fall

Pretty Good.

I recall a few minor fumbles early on (getting negatives wrong), but other then that the writing quality is high. 

Plot follows the system apocalypse pattern, with the variation that the Mc is alone for a long time at the start.

That gives us a solo perspective on the changes in the world and mc character. It does however mean there aren't really any supporting characters, dialog or character interaction for about 70 chapters.

To me that makes the first ark feel slow, and it becomes a bit of a slog later just going from one fight to another. Thankfully things pick up with that arks ending. We get increased pace, and an interesting supporting cast. Followed by exploration of the post system World and setting. The wider multiverse world and power system aren't the most well explained, but they are at least consistent and not wildly changeable based on however the author was feeling ons given day.

That does leave the Mc feeling a bit bland though. He isn't exactly cookie cutter, and he's definitely not the edgelord type, but his driving motivation is "find his family" which is (not unfairly) the most commonly used in sys apoc novels. Finding his family in the world of a novel of course means he must become and remain the most powerful man in the world. Establish his own kingdom, and butt heads with the old world government. Who are of course all morally bankrupt and corrupt. That's pretty cliche if you've read a few of these types of novel. It is however well executed, with a few nice details to keep it interesting.

All in all by ch190 I'd say this is a Good novel.

It's not spectacular, blow your mind must read level. 

It's not just a  "Meh read if you're bored and have nothing else" novel either.

If you want a sys apoc novel, with and kinda relatable mc this is a solid option.

I'm around half the story (760 ch) and I can say that is well written, the rythm is really high pace at least up until now, which can some time be good or bad depending on the kind or reader you are.

The power system is easily understandable, tho sometimes the leveling system get quite confusing.
