Ambitious universe building that starts small
Format: Kindle
Defiance of the Fall is in the Top 5 of my favorite progression fantasy stories (for reference, I think you should at least try the first book of all 5 series with the other 4 series being Primal Hunter, He Who Fights with Monsters, Azarinth Healer, and The Calamitous Bob). The scale of this series world-building is beyond any other series that comes to mind. And the crazy thing is that 16 books in, there's still a TON of room to keep building. I'm hoping the author can keep the series at this quality out to at least 30 books.
The series starts out slightly slower-paced, but 16 books in I think that was a good thing as it really sets up the main character and enables a slow build up of their new existence. You learn as the MC does, and at the beginning the MC is still struggling with the basics. But as the main character progresses, that 'world' gets more and more complex and grows vastly in scope (there's a whole giant universe out there), with that complexity being the main challenge of the series. When there is 16 books worth of progress, remembering all the details can get a bit challenging. Book 16 books in, I'm still eagerly reading every book that comes out.
All in all, I highly recommend this series and all of the others in my Top 5 list. If I had to round that out to a Top 10, other series I would recommend would be Paths of Akashic, Dual-Class, Grand Game, Unintended Cultivator, and A Thousand Li. None of those latter 5 are a strong as the top 5, but all are worth reading IMO.

Great LitRPG
Format: Kindle
Solid LitRPG stuff. It has all the hallmarks of the genre and they're executed well, your protagonist who starts off average and gets stronger and stronger, experiencing both great danger and great opportunity, taking risks that (usually) pay off.
Where it really shines is the worldbuilding; it's a somewhat slower burn in that respect but the writing does a good job of building a coherent, intriguing world with a ton of different factions and factions within factions with their own motivations. The history of the world is legitimately interesting and being cultivation-themed gives it a unique flavor compared to many others which are more straight RPG (and there's even a good in-universe reason for this).
My criticisms are fairly minor, the writing can be a bit dry or awkward on occasion "The situation clearly hinted at a situation where he would only need to...", and the universe and lore is expansive enough that it's easy to forget about some individual element on occasion.
This is an overall review of the series (16 books at time of writing).

good book, needs an editor.
Format: Kindle
The premise was good, and the story arcs were good. But the actual writing style of this book left a lot to be desired. I see the author is up to book 16 as of now. Hopefully they have fixed a lot of these minor issues.
