The speed at which human civilization expanded its territory also instantly jumped to a new level.

To date, human civilization has mastered three star systems surrounding the Kepler-452 star system.

Under Zero's control, the [Star Devourers] continuously mine the iron planets in these three star systems, providing the human fleet with a large amount of essential mineral resources.

To Lü Yongchang's regret, there are no habitable planets in these three star systems, and naturally, no extraterrestrial civilizations.

"Professor, what about the Sociology Department..."

Fang Xu knocked on Lü Yongchang's office door with a wry smile and reported softly, "They asked me about that matter again."

"No!" Upon hearing Fang Xu's words, Lü Yongchang stopped his work in annoyance. "Tell them that no trace of any inferior civilization has been found!"

"Forget about civilization, the fleet hasn't even seen a single insect!"

"Oh, right!" Lü Yongchang seemed to remember something, "Well, some single-celled organisms have been discovered on a planet. Why don't you ask the Sociology Department if they're interested in those things?"

Fang Xu chuckled awkwardly but didn't reply.

“That’s strange…” Lu Yongchang scratched his head vigorously, a look of confusion in his eyes.

"When we first left Earth, we encountered alien civilizations everywhere; there was no way to escape them."

"Now I'm going to look for them, but they've hidden themselves very well!"

"Tsk! What bad luck!"

Lu Yongchang looked at the brand-new desk in front of him with a depressed expression and complained in a low voice.
