After World War IV, the ecosystem on the Earth's surface was severely damaged, leading to epidemics and natural disasters leading to a serious population crisis. Faced with this situation, countries rushed to find shelter, and powerful countries such as the United States, Russia, and the United Kingdom were all struggling to find a place to settle, especially Germany and Norway when they encountered many protests in their countries.

Finally, in an emergency meeting of the United Nations, you agreed to let those countries go to your special cities for asylum. However, no one expected that place to be a city located in a space station flying in the Earth's stratosphere.

"I didn't expect you to build this place, why didn't you tell me?"

Russia smiled when she set foot on the space station, she and you had a close relationship, Nga felt sorry for not being able to help you.

"Oh my god! This place is wonderful, I hope it is as civilized and democratic as my country."

The United States came with dozens of suitcases, full of pride.

"Do you have residential areas? Where should we live?"

Slovakia and Japan asked curiously.
