The spacecraft continued its flight through the sky of Star Zone No. 171.
Su Yu stood by the window, with Cat Morning Star lying on his shoulder, both human and cat sizing up the novel world outside together.
For them, anywhere in Fige Hub was dotted with cities of the future.
Cities rose from the ground of the star zone, the construction reaching up to heights of three to four thousand kilometers!
Not only that, the underground structures of the cities were also incredibly dense, making the entire city very deep. In the same city, the altitude of where two residents lived could differ by four or five thousand kilometers!
Scores of intelligent machines shuttled through the city.
It was these intelligent machines that contributed to the city's construction, ensuring every resident could live a comfortable, high-quality life.
The sights before their eyes were beyond anything Su Yu had ever imagined.
