In ancient Huaguo mythology, five mountains floated on the sea not far from the "Returning Ruins." They were called Daiyu, Yuanjiao, Fanghu, Yingzhou, and Penglai.
These five mountains were lofty and majestic, dotted with beautiful pavilions and towers. They were said to be the dwellings of immortals.
When Qin Shi Huang sent Xu Fu to the Eastern Sea in search of the elixir of immortality, he had intended for him to find these five immortal mountains and visit the immortals.
The super space city before them was named Daiyu, clearly carrying the ancient aura of a place detached from the mundane world.
The scientists present were all elites in their respective fields. Naturally, they understood what a space city with ample energy supplies, self-repair capabilities, and a self-circulating ecosystem truly meant.
This was the space migration humanity had always dreamed of!
A generation ship was an enormous spacecraft with a complete ecosystem, one that could sustain humanity across generations.
With the speed of human spacecraft limited, building gigantic generation ships had also been a grand vision for human civilization's interstellar migration.
Yet the space city before them could accomplish that with ease!
This space city most likely used fusion reactors!
At that thought, Pan Jianguo could no longer restrain himself. He looked up and loudly asked the auxiliary AI system:
"May I ask who exactly built this space city? Which intelligent civilization does it belong to? Before we set foot here, had any Earthlings ever come here? Was that... developer really an Earthling!?"
With humanity's current technology, it was simply impossible to construct such a colossal space city.
Even the commander's Nanomachine Swarm technology had most likely come from an extraterrestrial civilization.
That was what Pan Jianguo was truly worried about.
Those not of our kind are bound to harbor
