I changed the timeline with the game.

Chapter 1131: This story continues from the beginning of the Fourth Era.
Hearing that she had unearthed such a shocking piece of core intelligence so quickly.

Although the rapid collapse of Meiji Shrine caused a crack in Su Wen's plan, the extremely rational man immediately paused the game.

Subsequently,

He planned to use the large library access granted to him by old Constance to search the corresponding database.

Browsing information within this large library is different from that in [The Wall].

He can ask a maximum of three questions, a restriction not applicable to scholars outside of major libraries:

But the moment Su Wen heard the name of this civilization, combined with his own self-awareness as a top-tier gamer, he knew it must be of paramount importance.

So the handsome scholar decisively drew the dormitory curtains, even though it was already late at night and the icy girl was fast asleep.

Outside the window, all things slumbered, leaving only the clear chirping of insects from the Lorenzriel demiplane, and the silent arcs of light, like night rainbows, cast by the massive steam fountain under the dark matter tides.

After taking a deep breath, Su Wen initiated a simplified ritual using his Lorenzreel teacher identity plaque.
The laws that allow countless pale silver threads and stars to blend together begin to emerge:
instantly,

As if programmed, the runes of the Age of Gods, representing omniscience, unfolded before his eyes:

(Utopia - Sefidalos)

Keyword analysis:
That was one of the deceased civilizations that had developed the technology to imprison gods and monsters.

Origin: The great sage Sephidaros, who once left the Great Library but has now reached the seventh level of transcendence.

The following important content involves the keyword 'betrayal of Dalos'.

The clock of destruction had completed a full cycle in the Third Era, marking the beginning of the Fourth Era after the collapse of the Federation of Men.

Sephiroth traversed the long staircase to godhood amidst the dust of the Orion Arm.

He used a nation that inherited the genes of the old human civilization as a natural fortress, and constructed a closed dome with a diameter of three hundred light-years using gravitational lensing.

It's a system built with 1.2 billion dark matter zero-degree observatories, simulating the crown left behind by the Magic Net genealogy, weaving stellar energy into a neural network covering the entire galaxy.
And seeing those holographic projections floating in front of his eyes,
Su Wen seemed to be witnessing once again the magnificence and romance of civilization.

He and Angelia witnessed the glory of the Third Age together:
But that technology belongs to the Silver Star City, a refuge on the frontier of civilization, not the ultimate depiction of a neural network:
"No wonder they were so arrogant after taking control of 'God's Abomination: Web Weaver (Jorogumo)' that they thought they could bring Tokyo under their control."

At this moment, Su Wen seemed to be connecting all the clues that had led him to Tokyo:
Whether it's Caroline who came here guided by the Ascension lineage; Miss Tsukishima who was harmed while seeking a recipient because she needed humanity; or the countless spiderwebs hidden behind the crimson cyber metropolis of Deep Tokyo.

even,

Those intricate structures that appear to be pure silver may have another name that is more familiar to countless researchers:

[Galaxy-level Intelligent Agent]

Thinking of this, Su Wen looked out the window, his fingertips lightly tapping the table.

This gesture usually indicates that he is deep in thought.

The handsome scholar seemed to see countless possibilities about history unfolding and being ordered before his eyes:
"So,
Destruction Sources: [Starship Intelligence Hub - Cultivator - Afanila], [Fictional Paradise - NO.7], [Questioning Disaster - Kunlun], [Purge Protocol - Emperor - Tursakla]
Could they be related to Utopia-Sephiroth?
End of the Third Era:

Genetic ascension triggered a self-destructive debate within the Human Federation regarding the purity of its humanity, ultimately leading to the disappearance of Endpoint and Lucia.

Early Fourth Era:

The great sage Sephiroth rekindled the flame, transforming the Fourth Age into one of neural networks and computational science, but also sowing the seeds for the birth of the source of destruction.

Su Wen depicted a magnificent panorama of the Star River civilization; perhaps even every sentence in that panorama existed within the vast expanse of time. Thus, it can be inferred that:

The Bounty Hunters Guild's [Deep Dive] is most likely different from Caroline's physical deep dive in Lorenzreel.

"Spiritual connection."

The Bounty Hunters Association has acquired the corresponding technology fragments.

Their research on Tokyo was even quite in-depth, but did that old man, Dean Constance, already know this all along?

Su Wen suppressed his doubts.

He now possesses too much information that he cannot share with others; some of it he can only communicate with Duchess Angelia when he has the chance.

after all,

If his intelligence deduction is correct

The space station where Angelia's mother, Dr. Pamela, was located was most likely not a relic of the Third Era.
even,

Its timeline is later!
It is very likely the product of analysis of a sub-civilization after the destruction of [Utopia-Cyfidaros].

No wonder Angelia still couldn't find any information about a similar space station, even with the help of the Storm Witch's data network.

in other words,

Sephiroth, a seventh-order god, a traitor to the Great Library, and a great sage of human civilization.

He is most likely the successor of the [Ascension Lineage: Prometheus].

The timeline belonging to civilization has begun to gradually become clear before Su Wen's eyes.

But as a scholar,
He understood that all he currently possessed was merely deduction, and that it was his duty to derive the truth from those deductions.

Su Wen didn't immediately try to communicate with Angelia about much, as he hadn't been separated from her for very long since the previous game, "Number Thirteen - Later Stage".

The most important thing now is...
He needed to finish reading the materials he hadn't yet completed, otherwise he would be wasting the precious opportunity that old Constance had given him:

(Utopia-Cephidalos, which continues the genealogical knowledge of the Great Library: High-Dimensional Neural Networks)

That was the ultimate celebration of divine engineering, and also the earliest prototype of the shackles of humanity.

After that,

The gods, Sephidaros, used dark matter as ink to trace miracles among the nebulae, but in doing so, they gradually erased their humanity.

Therefore, when utopia ultimately fails to meet everyone's expectations,
It's time to wake up from this dream.

The slumbering cult of the abyss was the first to leave Utopia, because there was nothing left there for 'He' to desire.

The divine creatures, a mixture of gods and desires, continue to awaken from the folds of time and space, while Sephiroth's proud closed system becomes a golden shackle that imprisons him.

This was the end of that civilization, but it also became a prison for countless divine monsters.

—The Great Library Recorder, 'Seagull School - Tallinn Vernon'
After the 70,000th star destroyed in Utopia-Cephidalos.

It was contained atop the Civilization Stone Tablet in District 728.
Having read this far,
Su Wen had already clearly understood what had happened to this civilization:
