Another cylindrical creature uttered its own question.
What should we do then?
The Alliance has searched all possible regions in the Laniakea Supercluster where four-dimensional cavitation might exist, but...
[Continue the expedition.]
As a new electromagnetic wave arrived, the orange mist dispersed once more, and an even taller intelligent being emerged from it.
The Empire has decided to restart the intergalactic leapfrog program, moving towards the Centaurus Cluster and the Hercules Supercluster.
[Continue searching for four-dimensional cavitation along the Hercules-Corona Borealis Great Wall.]
[The Cleaner Civilization can find four-dimensional vacuoles, and so can we.]
The electromagnetic waves slowly dissipated, and the interior of the starship returned to silence.
The orange-yellow mist gradually slowed down until it stopped.
The tall, cylindrical intelligent beings once again disappeared into the thick fog.
for a long time.
With a flash of light, the spacetime around the giant source of light underwent a violent distortion.
In a flash of intense light, the massive fleet vanished without a trace.
...
at the same time.
Human civilization has officially entered the Milky Way-Andromeda Galaxy Bridge region and embarked on a journey to explore the Andromeda Galaxy.
In the vast universe, a tiny fleet of five hundred starships silently sails through the silent darkness.
The starlight from infinity was so dim that it could not illuminate the path forward for the fleet.
One year... two years...
Time slips away, bit by bit.
For a near-level 7 human civilization, traversing a river system would be extremely long and tedious.
The surrounding scenery remained almost unchanged, and only an AI like Zero would not get bored with this monotonous journey.
Earth year 5303.
For the first time, the fleet exited faster-than-light warp drive mode—the warp drive of [Kuafu] malfunctioned.
Not only Kuafu, but also the more than 500 escorting starships experienced various malfunctions under the invisible, sharp blade of time.
Under Zero's control, the microcosm port slowly opened, and engineering ships and supply transport ships sailed out one after another.
The temporary starship factory automatically unfolded in this void, and a large number of robots and robotic arms began maintenance work.
After six months of repairs and maintenance, the restored Kuafu once again followed the escort fleet into a faster-than-light warp state.
The year is 7139 in the Earth calendar.
This marks the sixth time the fleet has exited the faster-than-light warp state.
It has been only 191 years since the last time.
The reason for exiting the faster-than-light warp drive was not due to factors within the fleet itself—ahead of the fleet, a massive rogue planet was "speedily" flying towards Andromeda.
This is the largest celestial object encountered by the human fleet since entering the star bridge.
After a brief moment of deliberation, Zero sent several probes toward it.
That was a gas giant.
It also retains a considerable amount of hydrogen and helium—the planet's internal temperature allows these hydrogen and helium to exist in gaseous form.
This is a gift from the universe to travelers.
Without hesitation, Zero controlled [Kuafu] to open the port of the microcosm, bringing this planet that had been wandering for an unknown period of time into the microcosm.
The year is 8713 in the Earth calendar.
The Human Alliance fleet has broken out of its faster-than-light warp state for the 10th time.
Inside the Earth, Lü Yongchang awakens from hibernation.
This is his fourth time waking up.
Theoretically, the human fleet should be able to reach the Andromeda Galaxy by the time they awaken next time.
Because of the existence of the microcosm, the Academy of Sciences did not completely stop its research work during the more than four thousand years of travel.
During the intervals between hibernation, researchers launched a scientific research "relay race".
Simply put, it's a relay race where people take turns conducting basic research while they're awake.
Although it is inefficient, it is durable.
The original spacetime theoretical model has been further improved with the "experience pack" provided by the [Shepherd].
As Lü Yongchang reviewed the achievements of the scientific research "relay race," inspiration began to rise in his mind.
He seems to have touched the threshold of a level seven civilization.
He recalled the two-dimensional fragment constraint device from back then, and the inspiration in his mind became clearer.
More advanced applications of space appear to be built upon dark matter.
From matter to antimatter, and then from antimatter to dark matter.
Lü Yongchang nodded subconsciously; this made perfect sense.
He got up, climbed onto the back "deck" of the robotic arm, and gave Zero a command.
"Take me to the observation deck."
...
【Earth】, observation deck.
Lü Yongchang looked out the porthole.
Seven stars, encased in a Dyson sphere, orbit stably in the center of the microcosm under the influence of a unified field, forming a stable seven-star system.
Driven by the catalytic mechanism of stellar core reactions, these yellow dwarfs are rapidly releasing their energy.
In just a few thousand years, they have lost the energy that could have sustained them for billions of years.
All of this energy was converted into antimatter by the Dyson Sphere system, which then powered the entire Human Alliance fleet.
Further away, the microcosm port has already been opened.
One after another, engineering and transport ships emerged to carry out a six-month maintenance operation on the starships in the vast universe.
Over the course of thousands of years, Kuafu and his escort fleet underwent almost complete replacement of all their internal systems, except for their outer armor.
So here's the question?
Are the current Kuafu and its escort starship the same Kuafu and its escort starship that were when they left the Milky Way?
This question suddenly flashed through Lü Yongchang's mind.
He didn't know the answer, nor did he want to delve into it.
"Professor, the remaining resources in the microcosm have dropped to the level two alert level."
A synthesized electronic voice suddenly rang out, interrupting his wandering thoughts.
Lu Yongchang snapped out of his daze and turned his gaze to the holographic projection that had automatically unfolded beside him.
Level 2 alert line.
In other words, 40% of the resources in the microcosm remain.
It's not a big problem.
The voyage is 80% complete, and there are more than enough supplies left.
He raised his hand and swiped it a few times on the holographic projection.
A scene of the vast universe appeared before his eyes.
The Andromeda Galaxy, which was once only the size of a light spot, has now fully revealed itself to human civilization.
Andromeda Galaxy
That is a galaxy much larger than the Milky Way.
The brilliant light of the stars emanated from within, illuminating the cold hulls of the human fleet across vast distances.
As for the Milky Way galaxy, which was once so vast, it has become the Andromeda Galaxy.
It turned into a barely perceptible, dim spot of light.
Milky Way (red circle)
The rise and fall of human civilization is all contained within that small, dim spot of light.
The Milky Way arc is complete.
