Rookie Detective

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!
