I’ll start by saying this book is a Dungeon Core Litrpg, and it is different enough from older popular ones to be well worth picking up in its own right.
The novel is centered on a dungeon but it does have a MC human as well as dedicates chapters to developing the Main Antagonist of the Novel. The LITRPG elements are extremely well done and more loot and mob focused then specfic stat focused. In my opinion It is a nice change of pace. The Dungeon is likeable and has alot of quirks that bring humor to the story. Overall i would recommend picking this book up and giving it a listen ASAP if you enjoy other Dungeon Core or LITRPG. One issue i have with this novel (which maybe more focused on later given this is the first installment) is lack of grand world building, the local map so to speak is pretty fleshed out but its hard to grasp the world at large fully in the first novel. However, there is a bit of foreshadowing that this maybe discussed and fleshed out in later entries and it doesnt take anything away from the book.
