Fantasy

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!
