A white architectural marvel.

A scene steeped in divine splendor.

Above stretched a flawless azure sky, pure and unblemished. The surroundings were adorned with white buildings that seemed to float atop the clouds. Such a breathtaking sight would leave any earthling in awe.

But Noah didn't have the luxury to marvel at the scenery. His gaze was utterly captivated by an otherworldly beauty lying nearby, as still as Sleeping Beauty.

She had snow-white hair and wore a close-fitting, white-and-gold garment that accentuated her perfect proportions. Her aura radiated a mixture of coldness and majesty.

Noah was in complete shock.

All he did was head downstairs to collect a delivery. He hadn't been hit by a truck, nor was he some unlucky high schooler from an island nation.

How did this even happen?

Crossing over to Teyvat? Sure, no complaints. But why was the landing point Celestia?

"The Sustainer of Heavenly Principles is going to wake up any second now and kill me…" Noah stared nervously at the goddess-like woman who seemed to be in deep sleep.

Before he could fully grasp his situation, a burst of blinding white light overwhelmed his vision.

The light came quickly and faded just as fast. A surge of divinity, supreme and absolute power, coursed through his body.

He had become the Heavenly Principle!

The former Heavenly Principle, Phanes, had perished shortly after the Khaenri'ah Cataclysm five centuries ago. Before their death, Phanes entrusted all authority to be safeguarded on Celestia by Asmoday, one of the Four Shades and Ruler of Space, waiting for the next individual to assume the role of protector and overseer of Teyvat.

Now, by some cosmic twist of fate, Noah had inherited this immense power.

"So, I just snatched someone else's chance?" Noah's face showed a complex mix of emotions, though his heart pounded uncontrollably.

Inheriting an entire world upon arrival placed him among the top-tier protagonists—the kind that start at the very top.

While elated, he was equally apprehensive.

As Heavenly Principle, he now bore the weight of safeguarding all of Teyvat. Even Phanes, an immensely powerful entity, hadn't survived. How was a mere newcomer from Earth supposed to shoulder such responsibility?

The information conveyed from the Heavenly Throne painted a grim picture of Teyvat: the world's very foundations were riddled with holes. In less than a decade, Teyvat would collapse.

"The world will last only ten more years. To wear the crown is to bear its burden…" Noah swallowed hard.

With the Heavenly Throne came near-omniscient knowledge about Teyvat. It was as if he had access to the world's control panel. Yet the flood of issues now overwhelming his mind left him drenched in cold sweat.

Even with the full authority of the Heavenly Principles, solving Teyvat's problems seemed impossible.

"What now?" Noah thought aloud. "Do I enjoy the perks of being Heavenly Principle for a bit, then hand the throne to Lumine after she conquers the Seven Nations?"

This wasn't how he imagined a transmigration would unfold. No cheats? No advantages?

"System, are you there?"

"Heaven-Defying Comprehension talent from the Earth Mother?"

"Imaginary Tree, Quantum Sea—grant me your power!"

"Multiverse Chat Group?"

"Simulator?"

Noah muttered nonsensically, grasping at straws.

[Ding! System has received the host's call. Initializing…]

[Modifying template according to host's circumstances.]

[Treasure-hunting template switched to Dimensional Sovereign template.]

[Loading complete. Enumerating host's abilities…]

As information surged into his mind, Noah's eyes widened in astonishment.

A system! As expected of a transmigrator!

A familiar game-like interface appeared on his retinas:

[Name]: Noah

[Role]: Heavenly Principle of Teyvat

[Authorities]:

• Primordial Ring of Law (Incomplete): Governs all laws and authorities of Teyvat. Portions of its fragments have been used to create gods and can be reclaimed upon their deaths.

• Aether Anchors: Core structures stabilizing Teyvat's dimensional bubble within the Quantum Sea. Functions include creating false heavens and repairing leylines using Divine Nails.

• Light Realm Force System: Harnesses Teyvat's seven elements, creates Visions, and merges elements into Light Realm Force to craft all things.

• Human Realm Force System: Collects human faith to form Divine Seats, evaluates the strength of wishes, and distributes Visions. The culmination of all human desires becomes the Human Realm Force that weaves destiny.

• Constellation System: Determines the fate of all intelligent life in Teyvat, gathers Ascension Stars, and guides chosen beings to their Divine Seats.

Gaining clarity from the system interface, Noah began to calm down.

As the Heavenly Principle, his strength was undeniable; he wielded the majority of Teyvat's world authorities.

"System, what can you do?"

The priority was to understand his cheat's capabilities.

[Ding! The system has transitioned to the Dimensional Sovereign System.]

Functions:

• Search for world coordinates based on the host's knowledge of the multiverse..

• Establish portals linking different worlds.

• Facilitate the annexation of connected worlds.

• Design detailed plans for annexing different worlds.

"Annexing worlds! Such overpowered functionality?" Noah inhaled sharply.

[Ding. Correct.]

As he recovered from his shock, Noah quickly asked, "System, can annexing other worlds resolve Teyvat's impending collapse?"

[Analyzing solution based on Teyvat's current situation…]

[Ding! Analysis complete.]

Solutions:

 1. Incorporate foreign laws to enrich Teyvat's rule system and transform forbidden knowledge into beneficial knowledge.

 2. Absorb underworld or infernal dimensions to neutralize Abyssal energy and create Teyvat's own underworld and reincarnation.

 3. Assimilate external energy systems to refine Teyvat's Vision-based divine system.

 4. Merge annexed worlds into Teyvat or establish them as lower realms, strengthening Teyvat's foundation and barriers.

 5. Recruit deities from annexed worlds to bolster Teyvat's pantheon and enhance governance authority.

Upon seeing the dozens of options listed, Noah's last ounce of worry dissipated.

"A transmigrator with cheats is truly blessed."

Without cheats, he'd cower in fear. With cheats, he would punch through every obstacle.

Taking a deep breath, Noah steadied his excited heart.

"System, begin searching for world coordinates!"

[Ding. Based on the host's memory, three worlds have been located…]

[Demon Slayer] [Akame ga Kill!] [Inuyasha]

Looking at the three options that appeared before him, Noah was a little surprised.

He hadn't expected these three worlds to come up.

Was the system selecting worlds based on Teyvat's needs?

[Ding. Based on the host's world condition, priority is given to targets that can compensate for the world's deficiencies.]

• Demon Slayer: Incorporating this world's laws would improve the Vision-to-Godhood system by 5%. Annexation would grant access to Primary Immortality and a new set of rules called Paranormal Laws, which could break the single-attribute limitation of Visions.

• Akame ga Kill!: Annexation would reinforce Teyvat's world barriers, providing initial protection against Quantum Sea erosion and extending Teyvat's lifespan by 100,000 years.

• Inuyasha: This world possesses relatively complete laws governing the Underworld, Reincarnation, Demons, and a fragmented Divine System. Annexing it would neutralize the Abyss' harmful energies, allow Teyvat to establish a reincarnation system, and create a safer environment. Additionally, Demon Laws would enable elemental creatures to evolve towards demon-like forms, granting them intelligence and the ability to take human shape, thus improving Teyvat's ecosystem at its core. The fragmented Divine System could further refine Teyvat's pantheon.

• Annexing all three worlds would extend Teyvat's existence by 500,000 years.

Listening to the system, Noah's blood boiled.

Just imagining such a grand undertaking awakened his primal instincts.

"So, what's the plan to annex these three worlds?"

Anyone could dream up grandiose ideas, but the execution plan was what truly mattered. Without a feasible approach, it was just empty talk.

[Analyzing…]

[Analysis complete.]

• Demon Slayer World: The system suggested embedding the Vision-to-Godhood system into the world's myths, subtly rewriting its fate. Using the host's authority, the Primordial Ring of Law, Noah could absorb the world's laws and integrate it as a lower realm.

Noah furrowed his brow at the overly technical explanation but quickly pieced together the gist.

"So, I just grant people in the Demon Slayer world Visions, have Teyvat's people act as their historical gods or saints, and use that deception to seize control of the world's authority? Why make it sound so complicated?"

[Ding. The system will simplify the terminology if needed…]

"No, no, keep it as is. It's fine," Noah said flatly, refusing to admit he had struggled to understand.

"Continue with the plans."

• Akame ga Kill!: The same strategy could apply here. However, additional steps were necessary. The host's Human Realm Force System would need to gather faith from at least 80% of the population. Once this threshold was met, the world's authority would automatically shift to the host.

"Collecting faith? With how corrupt and dark the empire in Akame ga Kill! is, that's practically child's play."

Noah nodded in agreement.

Humanity was most prone to seeking salvation in times of despair, and the empire's common folk were undoubtedly the most desperate, comprising 99% of the population.

By sending down a "god" to perform miracles and save the people, success would be nearly guaranteed.

"What about the Inuyasha world?" Noah asked. "That world is much more structurally complete than Teyvat."

Although the upper limits of power in Inuyasha's world were slightly lower than Teyvat's, they weren't that far off. Top-tier demons could raze cities at will, their monstrous forms rivaling low-level Archons. Furthermore, that world once had gods, even if they had vanished as humanity took center stage.

Annexing the Inuyasha world wouldn't be easy.

[To annex the Inuyasha world, the Vision-to-Godhood system must become mainstream. The host must also use the Human Realm Force System to establish Divine Seats, appoint earthly governors, and assume control over mortal and underworld authorities.]

Noah's face twitched.

"Isn't that just reenacting the Archon War in the Inuyasha world?"

Indeed, the chaos in the Inuyasha world mirrored Teyvat's Archon War era. However, the scale was akin to a low-budget version of that legendary conflict.

"Anything else?" Noah inquired.

[All plans complete. After annexing the three worlds, the system will proceed to locate new world coordinates.]

"Got it."

Noah nodded. Now, it was up to him to execute these plans.

All the groundwork was laid. It was as though the meal had already been served—he just needed to eat it. If he couldn't handle this, he might as well let the Sustainer of Heavenly Principles smother him with her… divine assets.

"Next up, I'll prepare the Seven Nations of Teyvat for their roles in the plan."

Right now, Lumine was just leaving Mondstadt and heading toward Liyue.

Although Teyvat was a chaotic mess, the annexation plan could still be implemented immediately.

Mondstadt, Liyue, Inazuma, and Fontaine—despite their issues—had functioning governments that could carry out orders with slight adjustments.

Sumeru, however, was a disaster from top to bottom. Assigning them to manage an annexation would likely result in internal power struggles.

As for Natlan, the constant infighting meant they were too preoccupied to focus on external matters.

The worst, however, was Snezhnaya. While the Tsaritsa was reliable, her Fatui harbingers had effectively hollowed out her authority. Each of them was a backstabbing opportunist.

If he involved them in the annexation, they'd probably overthrow him as the Heavenly Principle the moment they gained power. No doubt they'd justify it with something like, "If an outsider like you can rule, why can't we locals?"

"The Divine Seats system makes contacting the Seven Archons pretty convenient, like a godly version of the internet."

Noah glanced at the Sustainer of Heavenly Principles, who lay in a deep sleep, resisting Abyssal corruption.

"First, I'll wake her up and summon the Four Shades for a meeting on Celestia."

Although Noah had inherited Celestia's throne and Teyvat's authority, he still lacked proficiency. It was like handing a toddler an AK-47—he barely knew how to wield it.

While he trusted the Four Shades not to attack him, he couldn't rule out rash decisions in heated moments.

The Sustainer of Heavenly Principles, Asmoday, was someone Noah could fully trust.

She was one of Phanes' shadows, tasked with guarding Teyvat. Harming Noah, the current Heavenly Principle, would be akin to harming the world itself.

"System, is there a way to dispel the Abyssal power afflicting Asmoday?"

[Ding. Analyzing…]

[Analysis complete.]

[The host can transfer the Ruler of Space's corrupted powers onto themselves.]

"Huh? Phanes died from this stuff. Wouldn't I keel over too?"

[The system ensures the host is immune to negative effects.]

Noah exhaled in relief.

"Next time, say everything in one go. Don't scare me like that."

[Ding. Adjusting communication protocols based on the host's feedback.]

"Awaken, my celestial fairy..." Noah placed his hand on Asmoday's chest.

Wow... bigger than they look...

A dark, eerie, cold energy erupted from Asmoday's body, resembling tentacles, and surged into Noah's.

[Ding! Abnormal energy detected. Activating antivirus protocols.]

The Abyssal power was instantly purged as it entering his body.

Asmoday's condition visibly improved. Her eyelashes trembled before her golden eyes snapped open, radiating a mysterious and overwhelming presence.
