World of 2138

As I woke up from losing my consciousness, I had memories starting to flash in my head. It was one of my past lives, where I was just an ordinary guy, nothing amazing. I worked a 9-5 job as a programmer for games. I could also remember that I loved anime, and you know what's funny? I reincarnated as one of my favorite characters, even though I didn't know it at the time.

As I looked around, I found myself in a world I didn't quite remember. It was hard to breathe, with the sky always hidden behind thick, suffocating black smog. Towering skyscrapers loomed over me, their cold, metallic exteriors reflecting the harsh, artificial light that permeated the city.

Nature had been almost completely destroyed, leaving behind a desolate and bleak landscape. The once vibrant greenery had been replaced by cold, lifeless concrete. People in the streets hurried past, their faces hidden behind masks designed to filter out the toxic air.

I was in alleyway, and the sight that greeted me was chilling. It was as if I had entered a nightmarish scene from a dystopian movie. Lifeless bodies lay scattered across the ground, their ashen faces contorted in expressions of agony. The air was heavy with the stench of decay and despair.

As I cautiously made my way through the alley, I couldn't help but wonder how this world had come to such a grim state. Memories began to flash in my mind, remember my past life as an ordinary person. I remembered working a mundane 9-to-5 job as a programmer for video games, and my love for anime.

As I continued to explore this strangely familiar yet advanced world, thoughts raced through my mind. It bore a resemblance to my old world, but there was an unmistakable air of advancement and innovation that set it apart.

Upon leaving the alleyway, I found myself amidst a bustling urban landscape. Billboards adorned the skyscrapers, each one promoting products and services promising "fresh clean air," a precious commodity in this polluted environment. One particular advertisement caught my eye, featuring a game called "YGGDRASIL." The name triggered a cascade of memories, and it suddenly clicked into place.

I realized that I had somehow ended up in the world that Suzuki Satoru, the protagonist of a well-known story, hailed from. The world of YGGDRASIL, a place of virtual adventures and fantastical realms, was now my new reality. It was both thrilling and perplexing to find myself in a world that I had only known through stories and games. 

As I continued to walk through the bustling streets, I couldn't help but notice the curious gazes of the people around me. It struck me as odd, considering that I wasn't wearing a mask, but upon closer observation, I noticed that there were others who also walked without any facial coverings.

Determined to unravel the mystery, I made my way to a nearby building with reflective windows, hoping to catch a glimpse of myself and perhaps gain some insight into why I was drawing such attention.

What I saw in my reflection left me utterly dumbfounded. Staring back at me was a much younger version of myself, appearing to be in my twenties. It was an astonishing transformation, one that would undoubtedly make me stand out in this world.

I decided that it might be prudent to conceal my appearance using illusion magic. However, before I could do that, I needed to find a secluded spot where I could work my magic without drawing any more attention.

While pondering my newfound youthful appearance, I couldn't help but wonder about the existence of mana in this world and why it hadn't been harnessed to address the severe environmental issues that plagued this advanced society. The mysteries of this world continued to unfold, and I was determined to uncover the answers.

I managed to locate a secluded spot, away from prying eyes, and attempted to tap into the mana of this world. However, what I encountered was far from the pure and harmonious energy I had expected. Instead, the mana here felt tainted, heavy, and corrupted. The sensation was unpleasant, leaving me with an unsettling feeling that I had no desire to experience again. It was clear that the mana in this world was different, and not in a favorable way.

The corrupted mana left me feeling nauseated, and I couldn't help but vomit from the unpleasant experience. After cleaning myself up, I contemplated the situation. I recalled the mysterious orb that had fused with my forehead. Determined to understand its powers, I focused my thoughts and attempted to tap into it once more.

To my surprise, it responded, and I began to recall the capabilities it possessed. I was filled with a growing sense of understanding about the orb and the immense potential it held.

Orb of Nexuse

[Interdimensional Travel] This ability allows the user to effortlessly traverse between different dimensions, worlds, and realms. They can access parallel universes, alternate realities, and hidden dimensions at will, making them a true interdimensional traveler.

[Sub-Ability: Memory Unveiling] (4 uses)

When the user touches their Orb, they gain access to the first memory from one of their past lives. This memory provides insights into their own history and knowledge of a past incarnation. However, the other three past life memories remain locked, shrouded in mystery. To unlock these memories, the user must reach a higher realm. Each unlocked memory grants them unique abilities and knowledge related to that specific past life.

[Genetic Modification] The user can use the blood and genes of other creatures and people to modify their own bloodline or genetic energy as required.

[Energy Transformation] The user possesses the unique ability to convert various forms of energy, pollutants, or elements into usable energy. To do so, the user can harness and manipulate these diverse sources, effectively transmuting them into the energy required for their purposes. This power grants them exceptional versatility, allowing them to adapt to different situations by absorbing and converting the energy or elements around them, making them a formidable force in various scenarios. User can also store the energy into the pocket dimension for later use. 

[pocket dimension] As the user becomes stronger, they can create an inventory that expands in scale. At its highest potential, they can create a pocket dimension, ranging from a mini universe to a full-sized universe. the user can use his energy to Create a real universe although this will be hard to do, since the user needs to be a God of a universe. the more energy it holds the more the pocket dimension grows over time. 

As I sat down, I contemplated the abilities of the Orb of Nexuse. I had already learned that its energy transformation capability could convert corrupted mana into usable mana. Now, I wanted to explore the synergy between energy transformation and how the pocket dimension grows from that energy.

As I contemplated my newfound abilities, I muttered to myself, reflecting on how [Interdimensional Travel] had brought me to this world and how [Sub-Ability: Memory Unveiling] had facilitated the recovery of my lost memories. These revelations filled me with a sense of wonder and curiosity.

With determination, I began to collect polluted mana from the surrounding environment. The energy transformation skill allowed me to purify this corrupted energy, rendering it suitable for use. It only took me a matter of seconds to gather enough mana to perform my next experiment.

I diligently collected mana from the environment, channeling it into my pocket dimension to test its capacity. As the hours passed, I observed the pocket dimension gradually filling up with the stored energy. It became evident that the more energy I deposited into it, the more the pocket dimension expanded and accommodated the surplus mana.

After two hours of this experiment, I realized that my pocket dimension had reached its limit for the time being. It appeared that the dimension would grow overtime, satisfied with the result, I decided to leave the energy stored there for future use.

Using the illusion magic at my disposal, I concealed my true identity, disguising myself as an ordinary individual. I made sure to hide all traces of my Djinn equips and presented myself as an unremarkable guy in this unfamiliar world.
