A small Unnamed Galaxy lay at the boundary between the Boötes Void and the Shapley Supercluster.
Because it was close to the Boötes Void, this region of space was exceptionally empty-there was not even a second galaxy within tens of millions of light-years.
The Human Fleet, which had traveled from afar, was resting and refitting in the galaxy's Central Black Hole Region.
Replenishing supplies, modifying starships...
For Human Civilization, which had only just mastered Four-Dimensional Technology, there was never enough time.
Inside the Human Federation's micro-universe.
A shuttle approached from the distance, rapidly closing in on the Dimensional Research Center.
It gradually slowed and headed toward the harbor at the bottom of the Research Center.
Under Zero's control, a guidance beam based on the grand unified field drew it into the harbor.
The shuttle's hatch opened, and a figure emerged.
"Academician Wilson, Chief Lü is in Laboratory One of the Dimensional Research Center."
As the electronic synthesized voice finished speaking, a navigation marker created by a holographic projection appeared before him.
Academician Wilson, whose hair was beginning to gray, nodded, then hurried after the marker.
Whoosh.
The doors to Laboratory One of the Dimensional Research Center slid open, and hurried footsteps rang out.
Then came a call, deliberately hushed.
"Professor! Professor!"
Hearing the familiar voice, Lü Yongchang set down his work and turned toward the newcomer.
He smiled. "Wilson, it's been a long time since I last saw you leave the Weapons Research Center."
"Professor, there's a proposal for a new type of weapon that needs your review." Despite Lü Yongchang's teasing, Wilson's face was full of urgency.
Lü Yongchang's expression grew more serious. "A weapon?"
"Yes. Some ideas for dimensional weapons," Wilson said gravely.
"They involve different dimensions... so I had to come to the Dimensional Research Center."
