If an entire world is likened to a bottle, the bottle cap acts as the barrier separating it from other worlds.

As long as the cap remains sealed, whatever happens in other worlds will not affect that world.

But when the cap cracks open even slightly, the "threads" of the two worlds begin to intertwine, inevitably leading to change.

What kind of change results, no one can truly know, because such transformation is inherently unstable.

The changes experienced by Mizuho Miyakoji and the others were precisely due to this crossing of worlds.

According to Lin Luo's speculation, the catalyst might have been his integration of the Bright Realm and the Crimson World.

At that time, his strength had reached the pinnacle below the Heavenly Tier, and under a sudden surge of power, he achieved the true Arrow Tier.

This breakthrough advancement served as the trigger.

Coincidentally, a portion of the inhabitants in the virtual city were modeled after individuals from other worlds, and his rapid demise caused the virtual city to slip from his control.

The detachment of the city and the catalyst for change intertwined, causing all those virtual people to transform into their real-world prototypes.

Naturally, they did not replace the original existences; they were more akin to "identical" counterparts from parallel worlds.

As for why Katsura Hina's virtual self disappeared, that was due to the Host's influence.

So, the most crucial question remains: Why did the Heavenly Tier become the catalyst for changing the world? It must be noted here that Lin Luo does not possess a complete understanding of the Heavenly Tier, but he already knows how to judge if someone has reached it: if one can transcend the world using only their own power, that person is a Heavenly Tier being! What does it mean to transcend the world? More accurately, it means transcending the world's inherent conceptual framework (worldview).

Take the Nasuverse as an example; its worldview includes the existence of parallel worlds, anchored by the Root, constrained by the World Will, structured by the Five Greats, and governed by the Twenty-seven Ancestors—this is the fundamental framework.

Any resident of the Nasuverse, whether from the main world or its parallel branches, cannot step outside this conceptual structure.

For instance, the Old Man of Gems travels between various parallel worlds.

Because parallel worlds are inherently part of the overarching worldview, he is not a Heavenly Tier being.

Or consider a Demon Lord falling into water and suddenly arriving in another dimension.

First, the existence of that other dimension is already part of the initial world's worldview; second, he did not achieve this through his own inherent strength, thus he is far from being a Heavenly Tier entity.

Even Doraemon, possessing countless overpowered gadgets and traversing past and future, remains confined within the worldview of its own setting.

However, if one day, Aozaki Aoko were to suddenly break free from the shackles of the worldview using only her own power and arrive in the A Certain Magical Index world...

she would be a Heavenly Tier being! Similarly, if Saten Ruiko were to appear in the Nasuverse through her own ability, she would also be considered Yajie (Arrow-Broken, implying a similar level of conceptual transcendence relative to her origin).

There is a vital point here: to transcend the worldview, one must rely purely on innate strength.

Any movement facilitated by external objects does not count.

For example, Lin Luo and the Host travel back and forth using the Heart Codex and the potential of the World Heart; this doesn't qualify them as Heavenly Tier.

Only those who move through sheer personal power, like Gui Qu Lai Xi or an Acting God, truly qualify.

To illustrate: imagine if one day, Kyon's Sister suddenly realized she was a creator god, capable of reshaping reality with a mere thought.

If she thought, "Well, in that case, I want to go to the Dragon Ball world in the manga to spar with the Saiyans, and maybe see who is tougher between me and Doraemon—that sounds fun!" and she actually went, then she would be Heavenly Tier.

As for the outcome of the match, even if a Saiyan could obliterate a multiverse with one punch and shatter ten galaxies with one kick, if you cannot escape the worldview...

I'm sorry, faced with the Heavenly Tier Kyon's Sister, the Saiyan would only face death.

Likewise, even if Doraemon's gadgets can alter causality, manipulate time, and make hypotheticals real, if it is unaware that all of this operates within the original worldview...

Then, unfortunately, it can only serve as Kyon's Sister's pet.

Is the Saiyan capable of destroying a multiverse with one punch strong? Of course, they are strong! Is the Doraemon capable of rewriting causality and making delusions reality strong? Of course, they are strong! If they are so powerful, why would they lose to the Heavenly Tier Kyon's Sister? Where exactly does the strength of the Heavenly Tier lie? The simplest explanation: the invincible Saiyan is only invincible within the Dragon Ball world; everything about them is dictated by the author's settings.

The reality-bending Doraemon can alter anyone, but it cannot change the author's settings.

They cannot leap beyond the worldview established by the author.

BUT! The Heavenly Tier Kyon's Sister has leaped beyond the author’s settings and is no longer bound by them, thus she faces absolutely no pressure from anything below the Heavenly Tier! It is purely a matter of transcendence.

Even if Kyon's Sister stood perfectly still, and the Saiyan annihilated everything in the entire multiverse, leaving no place for any living thing, the power of that worldview could not harm the "transcended" Kyon's Sister.

When the universe is destroyed, the Saiyan would soon self-destruct, but Kyon's Sister, with a casual wave of her sleeve, leaving no trace behind, could instantly depart to capture Doraemon in another world for fun.

This is the first stage of the Heavenly Tier...

perhaps inaccurate—Unaffected by a singular world's influence! Lin Luo can only perceive this first stage, but through it, he can deduce the subsequent stages.

If being unaffected is the primary level, then influencing the worldview through one's own being is the next stage, and completely rewriting that worldview is the stage after that.

Whether there are levels beyond that, he does not know.

Why could Gui Qu Lai Xi, despite facing high-level Law-grade weapons capable of affecting causality, accidentally obliterate a fleet capable of destroying a universe? It is because she rewrote the world's conceptual framework.

For example, if she uttered, "This multiverse should not possess Law-grade weapons," then, sorry, all Law-grade weapons would instantly become scrap iron.

Or if she changed the worldview to, "The use of Law-grade weapons incurs a devastating divine punishment," then the person attempting to use such a weapon would instantly die.

To put it more bluntly, an existence like Gui Qu Lai Xi is akin to the author of a novel.

When she enters a world, everything within it can be scripted by her.

Both the worldview and its inhabitants are subject to complete alteration with a mere thought.

Of course, judging from Gui Qu Lai Xi’s comment about "accidentally destroying that entire fleet," it suggests she rarely engages in the act of rewriting a world.

Although she can arbitrarily change a world's framework, any change she makes remains fundamentally a singular transformation—like turning a cat into a dog.

To someone who has no connection to that specific cat, what meaning does it hold? In conclusion, the ability to leap beyond the worldview is the most critical standard for judging whether someone has reached the Heavenly Tier.

How one achieves this state depends on the depth of their comprehension of the world and its conceptual framework...

Theoretically, worlds that possess more parallel realities offer a greater chance for their inhabitants to become Heavenly Tier beings.

For "Walkers" like them, leveraging the Heart Codex to traverse various worlds is undoubtedly the greatest foundation for achieving the Heavenly Tier.

Lin Luo, in particular, by forging contracts with the Hosts of different worlds, established connections to those realities—a shortcut envied by many.

As for why Misaka Mikoto could challenge the Heavenly Tier in such a short time, it is precisely because Neo-Shanghai had already connected with other worlds, providing her with a unique foothold.

Lin Luo could clearly perceive faint, ephemeral world energies spreading outward from the city towards the entire globe—energy flowing in from various other worlds.

However, even though Lin Luo could see this flow, utilizing this energy was impossible for him.

His current level was still too low, like a magic apprentice who has studied for only a month; even if handed a forbidden spellbook, he could not possibly learn the forbidden spell.

Additionally, Lin Luo observed another type of energy drifting upward toward the heavens.

If his intuition was correct, that energy was likely the power of faith.

Yet, although the people in this city believed in deities, they lacked anyone capable of properly channeling that belief.

The power of faith was scattered, with only a small fraction reaching the Sky City; over seventy percent of it was lost to the ether. "What a waste.

If all that faith power could be absorbed, not only would I benefit immensely, but the Sky City itself might even achieve deification.

Sigh." Lin Luo sighed heavily, feeling a twinge of loss.

Though he could perceive and alter the trajectory of energy, this ephemeral power of faith remained outside his control.

Just as a god can absorb the faith of followers but cannot force sentient beings to worship them, needing emissaries to continuously proselytize. "If only there were an Archbishop who could provide proper guidance," Lin Luo mused, stroking his chin.

Speaking of Archbishops, he suddenly recalled someone—that long-haired, knowledgeable fellow might be well-suited for the job, though convincing that cunning individual to join might prove troublesome.

Although GC had served as a Bishop for a time, she was currently cultivating in the illusory world, and she disliked the role of an Archbishop anyway, so there was no need to consider her.

After weighing all options, the Sky City lacked a suitable candidate.

In the end, Lin Luo could only issue a "Divine Edict," temporarily appointing Mizuho Miyakoji and Shion Tojo to assume the responsibilities of Bishops.

They were unexpectedly delighted by this.

Beyond having closer contact with the divine, the more faith the Temple gathered, the more divine grace their respective worlds would receive—a win-win situation.

With all matters concluded, Lin Luo departed from Neo-Shanghai.

Now that he knew the path to achieving the Heavenly Tier, he had no reason to hesitate.

The immediate priority was to use Fate as a sparring partner to enhance himself, both in realm and in strength.

Having a Heavenly Tier expert as a training partner was truly the best possible arrangement.
