A triangle is the most stable structure.
Whether in mundane knowledge or extraordinary wisdom, ancient wizards have summarized and refined a law that applies universally:
"All things come in threes."
Everything can always be categorized into three possibilities, three forms, or three states.
For instance, the three states of living beings: are life, death, and undeath.
The three states of matter: are liquid, gas, and solid.
Similarly, the entire world can be divided into three layers: the inner layer, the outer layer, and the layer in between.
In Lynn's understanding, this division corresponds to the microcosmic, the macroscopic, and the normal perspective.
The inner layer is the source of power, a place full of mystery and boundless secrets.
From Lynn's past-life perspective, this dimension would be considered the quantum real deep, elusive world beyond easy reach.
The outer layer, on the other hand, is the vast expanse beyond the wizarding world.
In the eyes of his past self, this would be the universe, an endless starry sky stretching into infinity.
The theory of the inner, middle, and outer layers is the foundation upon which the wizarding world has developed akin to Newtonian physics in Lynn's previous world.
Wizards draw power from the inner layer, channel it into the middle layer, and ultimately launch expeditions into the outer layer, exploring the mysteries of other worlds.
However, in this infinite universe, other extraordinary civilizations also exist.
The wizarding civilization is not alone other civilizations approach exploration in ways entirely different from wizards.
When wizards enter these foreign worlds, they often encounter suppression from those worlds, preventing them from exerting their full strength.
After all, some extraordinary civilizations perceive the nature of existence differently. Their methods of gathering power do not align with the wizards' approach of extracting energy from the inner layer.
This fundamental difference means that the laws governing each world vary, leading to distinct paths of extraordinary power. As a result, wizarding expeditions often face immense challenges.
Under such circumstances, the Interdimensional Purification Device becomes indispensable.
Once successfully activated, this device can forcefully transform an entire region to conform to the wizarding world's laws!
It restructures the world into an inner, middle, and outer layer, overriding its natural rules.
By doing so, it creates an environment tailored to the wizarding world's power system, ensuring that wizards receive the energy support they need.
"This device is truly domineering…"
Lynn murmured to himself.
It was like playing a game where each world had its own unique set of rules.
But with the Interdimensional Purification Device, all worlds must submit to the wizarding world's laws!
"Still, the knowledge involved in this is incredibly vast… no wonder Kark only gave me an introductory guide."
Lynn frowned slightly as he reviewed the documents in his hands, feeling a wave of exhaustion.
The complexity of this project was staggering. If one had to build an Interdimensional Purification Device from scratch, the prerequisite knowledge would be overwhelming. Even Morning Star Wizards far beyond his current level would struggle with such a task.
"Luckily, our research project is only focused on improving the existing device…"
A thought suddenly struck Lynn about the recent lockdown in the City of Machines, as well as the messages he had come across in the virtual world.
"Could this be preparation for capturing the Goddess of the Weave? Are they modifying the device for that purpose…?"
The more he thought about it, the more plausible it seemed, and a growing sense of unease settled in his heart.
At this moment, he had both good news and bad news.
The bad news: He had originally intended to avoid the war, yet he had somehow ended up right in the middle of a project refining the war machine itself…
The good news: As a researcher, as long as he held his position, even if the City of Machines fell or the world crumbled, he wouldn't have to go to the battlefield. His safety was relatively secure.
"I'm just a newcomer, and they let me into this project without even a background check. Although there are contractual restrictions, this does seem a bit careless…"
Lynn chuckled bitterly at the thought.
"It seems that my research department must have the lowest level of security clearance. In other words, it's both the simplest and the least critical."
Realizing this, the pressure weighing on his mind eased considerably.
With his talent, keeping this position shouldn't be a problem.
If he could successfully pass the trial period, he could officially begin his path to wizardry once his mental power reached the next stage.
...
Time passed slowly.
Ever since the City of Machines entered its wartime lockdown, all entertainment activities from the second to the seventh levels had been completely suspended.
Wizards who weren't required to go to the frontlines mostly lived a monotonous routine either working or staying home to cultivate their powers.
During this period, two of the people Lynn could consider friends, Martha and Darwin, had also left for different reasons.
Martha had gone to war, while Darwin had moved to the seventh level.
This left Lynn's life quite simple.
Aside from studying research materials and preparing for his internship evaluation, he devoted himself to studying the extraordinary knowledge of a First-Class Wizard stored in his mind.
Thanks to the Golden Scales, his mind was filled with insights from Maple, a high-level wizard, regarding the path of a First-Class Wizard.
Although many spells and secrets were bound by contracts and could not be revealed, the knowledge that could be shared was already immensely valuable.
This provided a clear and structured path toward becoming a Second-Class Wizard.
Moreover, this path was particularly suited to Lynn's situation.
As a Natural Wizard, he could directly follow in Maple's footsteps, setting him firmly on the right track.
The journey of a First-Class Wizard consists of three major stages:
The first stage was spreading one's mental power throughout the entire mental domain, allowing it to surge like an ocean, filling every corner and reaching a vast, boundless state.
The second stage involved compressing the mental domain and then expanding the mental power again, increasing its density so that it fully occupied every inch of the domain.
At this stage, a wizard would undergo cycles of refining and extreme trials until their mental power gradually began to show signs of materialization, eventually manifesting as gaseous mental power.
The third stage was the complete materialization of mental power filling the entire mental domain with gaseous mental energy to the point that further compression was impossible marking the peak of the First-Level Wizard realm.
For Lynn, the first step was to spread his mental power throughout his entire mental domain, making it surge like an ocean, filling every corner.
Typically, there were two ways to enhance mental power.
The first was through meditation and cultivation, a method that took an extremely long time.
This was especially true for official wizards, whose mental domains had expanded. To cultivate enough mental power to fill every inch of space could take decades or even centuries.
Therefore, in addition to meditation, external aids became crucial.
Whether it was the "Divine Blood Pill" that Lynn had previously consumed or various other potions that enhanced mental power, all could significantly shorten the time needed for a First-Rank Wizard to fill their mental domain.
For newly promoted First-Rank Wizards, First-Rank potions were extremely valuable and expensive, often unaffordable.
As a result, many First-Rank Wizards would choose to take potions from their Apprentice days. While these potions provided limited benefits, "even the smallest scraps count as nourishment," and they could still offer some assistance.
However, excessive consumption of any potion would lead to drug resistance.
Thus, taking Apprentice-level potions was merely a transitional phase.
Once a First-Rank Wizard had consumed all the commonly available Apprentice potions and gradually developed resistance, they would have gained enough strength to seek out First-Rank potions, accelerating their cultivation progress.
According to the will of the Maple Tree, there was an essential piece of knowledge for Nature Wizards.
Without guidance from an elder Nature Wizard, Lynn might never have realized this.
This knowledge pertained to the special role of Transcendent Plants for Nature Wizards.
The first time Lynn heard of Transcendent Plants, he thought they bore some resemblance to the concept of a second soul.
In reality, they did share some similarities, but Transcendent Plants were not second souls they were second bodies.
Just like the will within the Maple Tree, when Lynn's body was taken over by an otherworldly being, the Maple Tree still provided him with a place to reside, allowing him to survive.
This was closely related to the resistance developed from taking potions.
If a newly advanced Nature Wizard developed resistance to Apprentice-level potions, they did not need to immediately switch to First-Rank potions. Instead, they could use Transcendent Plants to assist these potions.
By doing so, Transcendent Plants could also enhance a wizard's mental power.
For Nature Wizards, Transcendent Plants and their physical bodies functioned as two independent entities.
Though they had only one soul and one mental domain, through these two bodies, they could develop double the resistance, maximizing resource efficiency and accelerating mental power growth.
After all, the value gap between Apprentice potions and official Wizard potions was immense.
However, at this moment, Lynn was still experiencing a period of mental power surge and had yet to put this newfound knowledge from the Maple Tree into practice.
As time passed, the shadow of war loomed over the City of Machinery, casting a solemn atmosphere over the entire metropolis.
Yet, the war had little impact on Lynn.
Thanks to his innate talent, he smoothly passed the internship assessment and officially became a member of the research team.
Upon becoming a full-fledged employee, he signed a detailed and fair contract and was finally freed from his cramped single room.
Now, he was eligible to enter the research department and participate in more advanced work.
Standing at the entrance of the thirty-second floor, Lynn swiped his access card and walked straight toward the deepest part of the facility.
The metallic floor beneath his feet was pristine, reflecting the sterile precision of the environment. Each step produced a faint echo, adding to the vast and solemn atmosphere.
Every few steps, he encountered a checkpoint some operated by puppet mechanisms, some patrolled by wizards, and others guarded by complex security measures.
Each layer of security underscored the research department's unwavering commitment to confidentiality.
After passing through five or six checkpoints, Lynn finally arrived at the entrance of the research sector.
Along the way, beyond the standard checkpoints, he sensed multiple waves of strong detection energy scanning his presence.
He could feel that the wizards conducting these scans had already reached the stage where their mental power had begun to take on a gaseous form a testament to their formidable strength.
The stringent level of security surprised Lynn, deepening his respect for the secrecy of the research department.
At the entrance of the research lab stood a cold-faced wizard.
Taking Lynn's citizen token, the wizard carefully examined it for a few seconds. Once confirming his credentials, he indifferently gestured for him to pass.
In front of Lynn loomed an enormous metal door, its frame embedded with intricate and mysterious engravings. These symbols seemed to radiate a silent yet invisible force, exuding a deep, subdued glow.
Suddenly
Buzz!
The metal door trembled slightly, emitting a deep, resonant hum.
A dazzling white light seeped through the door's cracks, accompanied by an almost imperceptible scanning wave.
As the wave swept across him, the door slowly opened, allowing Lynn to step inside.
However, the sight that greeted him was nothing like what he had expected.
Rather than a sterile, high-tech metallic chamber, he found himself in a surreal, dreamlike landscape, filled with lush greenery and the chirping of birds.
Above, the ceiling was no longer a cold metallic surface but a vast, azure sky dotted with drifting white clouds and a golden sun casting warm rays upon the land.
The air was fresh and invigorating, carrying a soothing tranquility.
Lynn could even feel the golden sunlight gently warming his skin, reaching deep into his soul with an indescribable comfort.
"The technology here must be the same as that used in certain regions of the City of Machinery…"
Lynn mused, a hint of curiosity stirring within him as he retrieved his flying motorcycle and headed toward his assigned research group.
Had he not been forewarned, he might have mistaken this place for an entirely different world.
The serene beauty surrounding him was utterly at odds with the notion of a research facility.
After traveling for some time, he gradually descended onto a landing platform. Surveying his surroundings once more, he couldn't help but marvel:
"I wonder how many simulated worlds this research lab can create… The battlefield where the City of Machinery's army is currently waging war is likely in an environment just like this…"
Recalling his initial arrival here, he felt a lingering sense of nervousness.
Taking a deep breath, he regulated his emotions before activating the permanent wizardry imprint within his mental domain, beginning to absorb energy particles.
Click.
As he stepped onto the platform, he suddenly felt a dramatic shift in the world around him.
The reality before him twisted and changed, revealing a domain brimming with immense pressure and hostility.
It felt as if he had stepped into an entirely new world one that was inherently unfriendly to wizards.
The very fabric of the environment seemed to be filled with malice, as though countless invisible forces were launching attacks at him.
The permanent wizardry imprint on his body flickered with radiant energy.
It was a sign that his imprint was actively consuming stored energy particles.
