When the land was occupied by demons, people had no choice but to flee to the sky. After transmigration, Ricky found that he had become the City Lord of a Sky City. He quickly became familiar with this new world and established a clear direction for survival, which was to resolutely engage in farming (kingdombuilding)! He would farm (kingdombuilding) diligently, develop vigorously, and then gallop through the skies. If anyone disagrees, then launch a great sky battle. Or a war!
If the ending of Edgerunners hurt, this story is for you. It keeps the feel of Night City, but the new David takes a different path. You can tell the author cares about the characters and the story. It’s a well-done 'what if...' scenario.
