"4.7 million light-years is indeed quite close by cosmic standards.
After all, our Noah Civilization is merely a low-level cosmic nation.
Once you see a high-level cosmic nation, you'll understand just how vast its territory is."
Black Feather spoke softly.
"Wait, what's a cosmic nation?"
Xu Jingming quickly asked.
Having lived two lives, he felt that his experiences were already rich enough.
Yet faced with the grand terms Black Feather described, he was still somewhat bewildered.
"I nearly forgot. You're a native and don't know any of this.
Fine, I'll first introduce some basic concepts about the universe."
Black Feather's delicate brows rose slightly as she asked, "The galaxy Blue Star is in is the Milky Way. Do you know how many Sun-like stars there are in the Milky Way?"
Xu Jingming immediately fell into thought.
Although Blue Star was covered by a membrane, it did not obstruct observations of the starry sky.
The basic subjects he had studied in high school had also covered knowledge related to space.
"More than 200 billion?" Relying on the memory of a ninth-rank expert, Xu Jingming easily recalled what he had learned.
"Wrong! There are 300 billion!"
Black Feather corrected him. "Still, being able to observe 200 million stars means your technological development is fairly decent.
Most Native Planets don't even have a concept of stars."
"Three hundred billion stars, each surrounded by many planets, much like your Solar System."
Black Feather continued, "And among those 300 billion stellar systems, around 4.5 million planets are inhabited by humans. We call these planets Life Planets."
"Humans live on 4.5 million planets?" Xu Jingming secretly clicked his tongue.
Blue Star had records of three civilization eras, spanning ten thousand years.
Yet none of those civilizations had left behind any record of contact with extraterrestrial life.
