After Lin Rui left Rui Fang's Armored Biological Research Institute, he arrived at the top of a high wall in the dock base's outer courtyard, and looked outward.
He was observing the Ninth Base City after its expansion.
The diameter of the upper district of this city was originally fifteen hundred kilometers, but now it has expanded to five thousand kilometers in diameter, with the area expanding more than ten times to an astonishing 19 million square kilometers, almost equivalent to a continent on Earth's mother planet.
And the city's outer wall conveniently encompasses a small part of Lin Rui's dock base at the eastern side.
The expansion project of the base city has basically been completed, and a larger powered artificial sun has been replaced.
However, construction sites and large building robots can still be seen everywhere, especially in the suburbs of the city, where construction is ongoing everywhere.
