Uses positive parts of litrpg without suffering from the negatives: It's more of a mechanism for the writer to get the story started imo, is explained in-story as how individuals interpret magic, and the importance of numbers diminishes as the heroine begins to actually understand how things work. This is a story, not just reading someone play a video game.
Chapters 150 to 200 (ish) are significantly darker than the rest of the story, but it returns to normal and remains that way afterwards.
I read original web novel, technically not Amazon version. I devoured all nearly 900 chapters that were available when I found the series, almost non-stop until caught up. I eagerly await all new chapters.
This story is in my hall of fame for best stories I've ever read.
