Inside a meeting room in Tianshu Underground City on Blue Star.
Half a year was enough for an Underground City to complete an upgrade, and enough for greenery to grow again in Blue Star's Arctic.
The World Tree that had first taken root in the Arctic was no longer a solitary miracle of life.

Humans had been forced into Underground Cities, like ants hiding from natural disasters, clinging to life beneath steel domes and a rationing system.
The global nuclear war that followed had only made matters worse.
But now, things had changed.
The life domains spread by the eleven World Trees were gradually suppressing the shadow left by the nuclear winter.

"How are the first residents who moved back to the surface doing?"
The official in charge of public welfare immediately replied:
