Above the earth's orbit,
After countless years,
There are countless space cities,
a self-sufficient space fortress,
Based on millions of people,
Maximum capacity can reach thousands of millions people,
From the picture, you can see that each side is 1 space fortress.
And the city below the distant place.
地球的軌道之上,
經歷無數年代之後,
出現了無數座太空城,
一種能夠自給自足的太空堡壘,
以百萬人為基準,
最大容量能夠達到千萬人,
從圖中可看到左右各1做太空堡壘,
和下方遙遠地方的城市.
