Jing Jiu was still thinking of this issue after he arrived in the apartment.
Why did the same civilization split into two separate sides?
Had the civilization here discarded the one over there, or the other way around?
Jing Jiu walked to the window and looked up at the sky above.
In the sky were the thin clouds, resembling those on Green Mountain, amid which there were many large platforms that were intermittently visible.
The platforms were not built in the space; in fact, they were on the mantle of the earth.
Many years ago, after the rocks and ores had been transported to the factories in the space, the working platforms were left behind. Afterwards, many buildings were constructed on them for humans to reside in.
The cliff where the New Era Institute was situated was in the deep part of the mantle of the earth.
Deeper still were the desolate neighborhood and the laboratory from which Jing Jiu had escaped.
