I built a floating city in the apocalypse

The end of the world is coming, the game system is loaded into the world, and the survivors are changing their jobs one after another, from mages to warriors, archers, and priests. One novice village and main city after another are built on the earth. Is this a game?
No, if you are killed you will die!
At this moment, Fang Bai, the inheritor of the ancient high-dimensional mage, closed the attribute panel and stood in the void. Behind him, the mage towers stood like pillars of heaven, and their grand voices echoed between heaven and earth for a long time.
"Floating city, take off!"
PS: The old book "The Real Game" with 270 million words and the old book "The Three Kingdoms Come to the World" with 178 million words are worth buying.
