Burnout Reincarnation [SLOW BURN COZY 'MAGIC CRAFTING' KINGDOM BUILDING PROGRESSION] (LitRPG elements) [3 arcs done!]

Archmund Granavale was nine years old when he remembered his first life as a (former) “gifted kid”. That world told him for years that he would grow up to do great things and change the world. Then he grew up, and he got stuck in a boring office job, and none of that happened. In this new world, Omnio, he can't relive that. At first, he wants to use all of the useless knowledge and trivia — science fun facts, recipes, and self-help books — that a "gifted" kid absorbs to either revolutionize this pre-industrial fantasy world or achieve total freedom instead of being bound by the rules of the nobility. But that all changes once a Dungeon Storm opens a passage to the underworld in his home county, sparking an empire-wide gold rush for its magical gems. If he wants either a quiet life or a career at the forefront of industrialization, he has no choice but to navigate the complex social landscape of the military, the nobility, and the masters of magic. He'll take every advantage he can get — magic gems, independent wealth, connections and the status to make them — and the knowledge of a burned-out gifted kid. This time, he will change the world — or at very least the path of his life. Even if he ends up burned out again. And using those goddamn spreadsheets.
