The distant Rising Sun looked like a little red ball, rather pitiful to behold.
The star was a little too far away, and the surface was somewhat cold. Without the protective shield overhead, ordinary humans would have found it difficult to live here.

The sun rose a little higher, illuminating the mountain range's cliffs, thousands of meters high. Unknown things kept flashing within them, like stars buried in the mountains-that was part of the earth's crust. It turned out he was still on the second underground platform; only above that mountain range was the true surface.
A great deal of information surfaced in his consciousness.
When the Dark Matter Sea invaded, the machines hidden within the sidewalls of the earth's crust would activate and link together, forming an immense gravitational force field.
That gravitational force field and the modified earth's crust would provide the Underground World with the strongest, most solid protection, while the buildings on the surface would be abandoned entirely. If the residents could not retreat underground in time, they too would be abandoned.
