Looking for Kingdom building novels....I'm a big fan of Release that Witch and The Tales of the Reincarnated Lord. I guess I'm more of a fan of that style. And I'm looking for anything good, so royalroad, kindle unlimited, novelupdates, etc are good .
Goblin Kingdom (if you didn't read it), it is not of the same style as the two you mentioned but a good one when it comes to kingdom building novels
Well, if you like someone who is smart or that learns with mistakes, don't read goblin oukoku, you'll get annoyed
Lord Kalvan of Otherwhen Daniel Black Play to Live The Casere Adventures of Conrad Stargard Magic Kingdom of Landover
