章 10: Theory of Parallel Worlds

But first, I have something important to do, something I couldn't do these days because of the work I had.

[Mmm, yes, nothing better than sleeping after many hours of work], Shiro murmurs with a lazy expression as she starts walking towards her house to take a huge nap.

(4 hours later)

Shiro shifted in her bed, her heavy eyelids struggling to open. A ray of light filtered through the partially closed curtains, painting her room in golden hues. With a deep and prolonged yawn, she finally woke up. The sound of Kurumi singing outside filled the room as she stretched her arms upward, feeling the pleasant sensation of muscles relaxing after a day of sleep. The gentle breeze coming through the window caressed her face, and she realized it was a new day, ready to face whatever the world had in store for her.

[Ah, how pleasant it is to wake up feeling the gentle breeze of my world… After this little nap, I think it's time to get back to work.], Shiro murmurs in a low tone.

After stretching a bit, she quickly gets up and tidies her bed, then goes out to start on the projects she had planned.

Today, she had planned to start with the creation of monarchs or the Magic of Parallel Worlds.

But upon further thought, she believes that creating the magic of parallel worlds would benefit her more, as it could increase her strength in different worlds and gain more experience.

Furthermore, recently, while reviewing her memories, she realized that the "Goddess D" governs the attributes of darkness and death.

In other words, if she trains in these attributes, she can increase her strength further; for example, with the attribute of death, she could create souls or an army of the undead capable of evolving, and so on.

What she means is that she didn't pay much attention to that before, and now, after analyzing it, she realized its significance.

The problem is that there is already a conceptual god of death here, known as the Black King.

The Black King, with his dominion over death, is basically Yogiri, as he can simply say "die," and with just that, he annihilates your body and soul without a chance for reincarnation.

That's why she wants to increase her strength, and that's not possible on the lower floors, as everything on the lower floors, she can easily create.

Although there are many things that don't serve her, there are also things that could help her; for example, in the Horn Tribe, she could learn the martial arts they use.

The problem is that, being a loner, she's bad at talking to others, and she doesn't know how to get to their tribe.

The problem isn't that she doesn't know how to get there, but if she suddenly arrives at their supposedly hidden village, that would look super suspicious and they might attack her.

So, let's scrap that idea; the only thing left for her is to create a magic that allows her to travel to parallel worlds.

According to her theories, beneath this multiverse, there may exist parallel universes of fictional works.

She divides parallel worlds into two groups. One, the upper worlds, which are formed by an infinite multiverse. An example of this is the Marvel multiverse.

The second group, she calls lower worlds, which are formed by a finite universe. An example of this is worlds like Naruto and One Piece.

That's why she plans to create magic that allows her to travel to the lower worlds because she's not crazy enough to travel to a multiverse like DC; that would be seeking death, and that's something she doesn't want.

In addition to that problem, there's also the energy cost; she still doesn't know how much energy it will cost to travel to a lower or upper world.

That's why she has to plan well a world that brings many benefits.

Although if she had to choose a world that would benefit her a lot right now, she could say it's the world of Naruto.

Since it's full of a pure energy called "Chakra," and the planets in its world are filled with pure energy, which benefits her a lot, a God who grows and lives on energy.

But well, she'll have to experience all that when she travels, if she manages to do so.

The first thing she has to focus on is the present, and what she has to do in the present is to create the magic of parallel worlds.

After finishing her internal monologue, Shiro left the house and headed for her favorite chair in the garden.

After reaching the chair, she sat down and began to think and study the memories she had about time travel and summoning circles.

In particular, Shiro focused on the dimensional summoning shown in Isekai anime. In the novels she was rereading in her memories, it is shown that through summoning circles, it is possible to bring someone from a parallel world to their own.

Shiro wants to find a way to reverse that so that, instead of summoning "something," she can move to that "something" she desires.

So, seeking a way, she concentrated to the maximum and accelerated her thoughts in a way that in her mind hours passed while in the real world, minutes and seconds passed.

She also found in her memories old books and worn scrolls. The "Goddess D" had been obsessed for years with the idea of traveling between parallel worlds and exploring alternate realities. She had tirelessly researched the theory of parallel worlds.

Her theories were good, and I have to say that it was to be expected from an intelligent being like her.

Combining her theories and Shiro's, to understand how traveling between parallel worlds worked, Shiro first had to delve into the underlying theory. The theory of parallel worlds was based on the idea that every choice a person made, every event that happened in the universe, created a branching in reality. This meant that at every moment, multiple timelines and realities coexisted.

Imagine a starting point, a moment in time when an important choice must be made. In one reality, the choice results in path A, while in another, with a different choice, path B is formed. This creates two parallel worlds, each following its own course of events.

Thinking and analyzing that, Shiro arrived at a definitive theory that would serve her and had the potential to work.

The theory suggested that parallel worlds were like layers of a cosmic onion, superimposed but inaccessible to most people. Shiro believed that the key to traveling between them lay in understanding the vibration of reality. Each parallel world had its own unique vibrational frequency, and if she could tune into that frequency, she could open a portal between worlds.

Focusing, Shiro began working on a complex spell. She used that theory and started creating a magic circle on her hand. In the center of the magic circle, she created satin patterns that continued to flow, metamorphosing and spinning, changing shape like a kaleidoscope. This metamorphosing kaleidoscope represented the infinite possibilities and parallel worlds. This kaleidoscope, Shiro believed, had special properties that could help her tune into the right vibration.

Shiro then began making calculations while channeling her magical energy into the circle. The kaleidoscope magic circle began to emit a soft glow, and Shiro felt her mind rising, connecting with the streams of energy from other worlds. At that moment, she saw flashes of alternate realities, worlds where circumstances were different, where she was someone else.

That confirmed to Shiro that Athena met her in a parallel world. Setting aside that, Shiro refocused on the magic circle.

However, the effort was overwhelming. The intensity of the magic she was invoking began to consume her. The magic circle flickered, threatening to collapse. Shiro knew she had to maintain control, but the power was immense.

Just when it seemed like everything would crumble, Shiro channeled her determination and focus. She closed her eyes and visualized the world she wanted to travel to. The magic circle stabilized, and a portal began to form in front of her.

The portal glowed with a dazzling light, showing a tempting view of another world. Shiro felt an irresistible attraction to the world her eyes were seeing, and without much thought, she took a step forward, crossing the threshold into a new world.

(N/A: Hey guys, how did you like the chapter? Did you enjoy it?

Also, as I mentioned before, I plan to create a legion of Monarchs completely loyal to Shiro. And I finally managed to complete the magic of parallel worlds. With that, the MC will have more power at her disposal and more possibilities. I would like you to come up with a good name for this magic because I'm not good at naming things. But first and foremost, as I always say, I'd like to hear your opinions and see your great ideas. The MC's first world is the world of Naruto.)
