Genshin Impact: I, Heavenly Principle, Will Make Teyvat Supreme

Eight auras emanating from the universe spread from Celestia across the entire cosmos.

The expanding Teyvat Universe seemed to have had stones dropped into it, creating ripples that altered the trajectories of countless galaxies on a grand macroscopic scale due to the influence of the cosmic aura.

This power acted only on a vast, macroscopic level. It did not interfere with anything within individual star systems, nor did it affect the major timelines or planar worlds.

Even if it did affect the timelines or planar worlds, no beings within them would be able to perceive it.

Cosmic aura is something only those who have stepped into the Supreme God tier can possess.

At this stage, a Supreme God within the Great Universe has ascended to become a grand soul on a macroscopic scale. Their very existence begins to correspond with the universe's large-scale structure.

What is meant by the universe's large-scale structure? It refers to the structure formed by countless galaxies.

Our local galactic group is made up of fifty galaxies, but this still does not qualify as a large-scale cosmic structure.

Only structures like the Virgo Cluster, composed of over three hundred galaxies, can barely be called large-scale structures.

Yet even that is not sufficient to describe the power of a Supreme God.

Even a Third-tier Supreme God's power has now reached the level of the Laniakea Supercluster.

The Virgo Cluster is but an insignificant part of a supercluster, as a supercluster consists of 100,000 galaxies.

This is what constitutes a true large-scale structure, also referred to as the supergalactic level.

Now that Teyvat has become a Great Universe, its Supreme Gods correspond to supergalactic-level, single-universe-scale entities.

Dozens of cosmic auras resonated and interacted throughout the universe, influencing the operational laws of the entire cosmic structure.

...

In the various timelines, Istaroth stood at the nexus points of time and space, observing the infinite expansion of all major timelines.

Endless timelines were being born from the expansion. Each one would become a cross-dimensional world, and each world would evolve into a small universe with at least a million galaxies.

In Istaroth's eyes, countless small universes layered and stacked within the main universe.

"Ah~ As expected of Master's arrangement! It's absolutely incredible! All the timelines have turned into small universes, it's outrageous!"

"Every Earth-based timeline has truly become a full-fledged universe!"

"This... this is practically a miniature multiverse!"

From the initial Demon Slayer World, Akame ga Kill World, Inuyasha World, DXD World...

These worlds no longer existed as simple timelines but had expanded from planetary scale into solar systems, galaxies, and even tens of millions of galaxies centered around those planets.

"As expected of Master!"

As the Sustainer of Heavenly Principles, Istaroth was well aware of Noah's cosmic layout.

The foundation for a multiverse had been fully established. All that was needed now was a continuous infusion of evolutionary force, and the universe would smoothly ascend to a weak multiversal level without bottlenecks.

"And I've become so strong now!"

Istaroth marveled at the cosmic aura spreading from her to all timelines and the fully integrated cosmic laws. She was deeply shaken.

As a Sustainer of Heavenly Principles and also a First-tier Supreme God, she possessed a portion of the Heavenly Principle's distributive power, as well as all conceptual laws of the entire universe.

At this moment, she herself was the entirety of the current Teyvat Universe.

Of course, this referred only to the main universe of Teyvat, not including the various timelines.

If those were included, it would approach a strong single-universe level.

Although the current Teyvat Universe wasn't yet a strong single-universe, it was already close. Once the gods fully digested the power brought by the universe's expansion, the universe would smoothly ascend to a strong single-universe level.

However, this still required a series of steps.

Master's plan was flawless—it laid the groundwork all the way to the weak multiversal level.

And how would they digest the power brought by the universe's expansion?

Naturally, through the Sovereignty of the Sun Contest and the Divine Collective Gift Games, fully igniting the universe's activity.

"Now I truly am a single-universe level entity! I, Istaroth, am a real powerhouse even in the super-multiverse! Eternal be Master! Eternal be the Heavenly Principle! Yay!"

Istaroth transformed into the form of a small sprite, cheering at the convergence point of space-time.

Radiating cosmic aura, she flitted endlessly between the small universes of the major timelines.

...

At this moment, the greatest transformation was occurring in the Abyss.

As the dark side of the universe, the Abyss bore the weight of its opposite—one could even call it an alternate shadow universe.

Rumble rumble rumble rumble...

The edges of the Abyss expanded without limit. Instead of floating landmasses, what now appeared were purplish-red galaxies—growing in number.

However many galaxies the main universe had, the Abyss now had just as many.

Moreover, Abyssal space continued to stack upon itself, forming time-space reflections.

Within these reflections were tunnels leading to the dark side of each small universe—linking them all together.

But the galaxies of the Abyss were far from as peaceful as those of the main universe. At their centers surged jets of negative energy spanning tens of thousands of light-years.

These were the flip side of black holes. In both the main universe and the small universes, black holes connected to the Abyss.

The center of the Abyss was also located directly beneath the continent of Teyvat.

This central Abyssal continent was only slightly smaller than Teyvat itself.

Rumble rumble rumble rumble—

A terrifying aura of infinite dread spread from the central continent, shattering numerous fragile floating isles.

Countless Abyssal monsters were flung from their landmasses by the impact.

Sinners mining in the Abyss all collapsed unconscious.

Unlike the Supreme Gods of the main universe, Aether, as the Abyssal Monarch, had no need to be gentle. He cared nothing for the lives of those sinners.

He unleashed his infinitely swelling, terrifying might without restraint.

"Hahahaha! So this is Second-tier Supreme God! A Cosmic Structure level? Powerful—unimaginably powerful! Hahahahahaha—"

Aether stood before his throne, laughing heartily.

Even with his usual composure, he couldn't suppress the joy in his heart.

In a single leap, he had risen from nebula-level strength to cosmic-structure level. This leap had crossed the galactic and supergalactic tiers—an unimaginable gulf.

In some cultivation systems, this leap alone would span countless realms.

Now, as he felt the boundless power surging within his body, he recalled his first encounter with the Heavenly Principle.

How lucky he had been back then. And now—how long had it been since then? And he had already become such a colossus of the cosmos.

"Long live the Monarch!"

"You idiot! Are you cursing our Abyssal Monarch to an early death?!"

"Our Monarch is eternal and undying—"

"Our Master shall reign forever—"

The earliest Abyssal gods, at minimum, had reached galactic level strength. Some had even neared the great galactic tier.

Feeling this supreme pressure, they cried out in frenzy.

Aether glanced over the endlessly vast Abyssal star region filled with cheering Abyssal gods.

"Surely I'm no longer at the bottom among the Supreme Gods."

With that thought, he turned to gaze at the main universe—his expression stiffened.

"Wait, what?! Even Rukkhadevata became a Second-tier Supreme God at this time?!"

At that moment—

Sumeru.

Buer sat peacefully upon her divine seat, her gaze gentle as she looked upon the Sumeru gods who had returned with her and were basking in the power of the cosmic expansion.

Behind her, a radiant Supreme God halo shimmered softly, emitting cosmic aura and tens of thousands of conceptual laws.

However, the radiance of universal laws that had spread across the cosmos lasted only thirty days.

When the gods of Teyvat returned to their respective communities and nations after the surge in their powers, they noticed subtle changes—and only then did they realize that a thousand years had passed.

While a millennium had wrought great changes elsewhere in the universe, the Teyvat Continent itself had not changed significantly.

At this point, the Teyvat Continent had become a true divine realm. Ordinary people were born with transcendent potential, enjoying lifespans of over a thousand years. With a bit of cultivation, they could live for several millennia.

Over the course of that millennium, Teyvat had changed a great deal, but for ordinary people, those changes occurred at intervals of decades—not too frequent.

And in a land where gods congregated, was worldly change really so surprising?

The most noticeable difference was the presence of roughly 100,000 celestial bodies—ranging from the size of apples to that of eggs—hovering in Teyvat's sky.

Some of these star-bodies were as small as a tiny Earth nation, while others were as large as Jupiter.

All were inhabited worlds.

The entire Teyvat Continent was now layered like a three-tiered cake.

The bottom layer was the vast Teyvat Continent, home to over seventy percent of ordinary people.

The second layer was the Divine Realm, where most gods resided.

The third layer was the realm closest to Truth, accessible only to Upper Gods who had mastered at least one complete law. The conceptual density here was too immense—lesser beings could not withstand it.

Though there were no restrictions on travel between the third and second layers for mortals and gods, most ascended gods preferred to establish their nations in the second layer.

In just a millennium, over 100,000 nations had been established on the Teyvat Continent.

Only Upper Gods were qualified to found a nation.

The lives of ordinary people and minor gods had gradually returned to peace over the past thousand years.

Noah had also fully digested his exponentially increased power and slowly opened his eyes.

In his golden irises was reflected the entirety of the Great Universe.

The moment he opened his eyes, the entire Teyvat Universe erupted in cheers, joy, and worship.

"It's time."

"The current divine system can no longer match the scale of the Great Universe. It's time for a change."

Noah extended his hand, and the polyhedral Heart of Teyvat appeared above his palm.

"Begin restructuring the divine hierarchy!"
