Reincarnation of the Last Magus Emperor

The 8 Blades Body Art, a unique and powerful body refinement technique created by Merlin, was based on a deep understanding of physical combat and mana cultivation. Unlike the Augmentation techniques used by human body refiners, Merlin's approach went far beyond enhancing the body with external mana; it was a form of true Demon body refinement that intertwined both physical and spiritual cultivation.

The 8 Blades Body Art drew inspiration from martial arts, where every strike—whether a fist, elbow, knee, or shin—was refined into a key element of his cultivation. The technique's structure mirrored the elements of his martial arts training, where these eight forms represented the various aspects of a body capable of refined physical control. Each part of the body—the two fists, two elbows, two knees, and two shins—was not only a weapon but also a critical part of the body's refinement.

In contrast, Augmenters were cultivators who used their mana cores to enhance their bodies through carefully controlled distribution of mana across their body. The process of augmentation focused on amplifying physical traits like strength, speed, and endurance, utilizing the mana core to fuel this enhancement. The more proficient an Augmenter became in distributing their mana efficiently, the more freely they could manipulate their bodies in combat, adapting to various forms of enhancement as needed.

However, Augmentation was not without its risks. The Augmentation Backlash was a painful and dangerous consequence that could arise from overusing mana. If an Augmenter pushed too hard and depleted their mana core, they would suffer intense physical pain as their mana pathways faltered and their mana core was strained. The backlash could range from moderate discomfort to extreme agony, depending on how severely the mana core was damaged. This pain was a direct result of the body's mana reserves being overextended, and if not managed properly, it could lead to serious injury or even permanent damage to the Augmenter's mana core.

True Demon body refinement, which was what Merlin practiced through his 8 Blades Body Art, was a more profound transformation. Rather than relying on external mana enhancements like Augmenters, Merlin's approach was rooted in the internal strengthening of the body itself. By refining his muscles, bones, tendons, organs, and even his mana pathways, Merlin was able to create a body capable of channeling and containing mana in a way that went beyond mere augmentation.

Each of the eight blades—the fists, elbows, knees, and shins—was not just a physical attack but a point of focus for the refinement of Merlin's body. His physical combat ability became intertwined with his mana pathways, allowing him to strike with the precision and power of a cultivated body that could contain and use mana naturally, without the external reliance of augmentation. The more he honed these techniques, the more his body became a vessel that could support and wield vast amounts of mana.

The distinction between Merlin's true Demon body refinement and Augmentation was significant. While Augmenters were limited by their mana core and were vulnerable to backlash if their mana core was overused or damaged, Merlin's method created a body capable of supporting continuous cultivation without these risks. His refinement was about true integration of body and mana, creating a form that could naturally endure and use mana, rather than just enhancing the body temporarily through external mana manipulation.

Merlin's approach allowed him to transcend the limitations of human body refiners, and his 8 Blades Body Art became a perfect harmony between martial prowess and mana control, a true embodiment of Demon body refinement. This transformation allowed him to avoid the risks of augmentation backlash while still achieving far greater physical strength and resilience, setting him on a path where he could fight not just as a mage but as a master of both body and mana.

As Merlin continued his rigorous training with the 8 Blades Body Art, a sudden insight struck him, one that unlocked a deeper understanding of the True Demon body refinement. It was during a particularly intense sparring session, where he combined the strength of his fists, elbows, knees, and shins into a seamless flow of attacks, that his awareness sharpened.

The strikes, each representing an essential part of the body—the fists for strength and power, the elbows for precision and control, the knees for flexibility and mobility, and the shins for stability and endurance—had always felt like separate aspects of his training. But now, as he executed them in rapid succession, the movements began to harmonize. The flow of mana through his body, which had once been limited to external usage or simple augmentations, began to merge with his muscles, bones, and tendons, and suddenly, his body and mana pathways were no longer separate entities. They were a unified force.

Merlin realized that True Demon body refinement wasn't just about enhancing the body with mana—it was about fusing the physical body with the essence of mana itself. Each strike, each part of his body used in the 8 Blades Body Art, wasn't just a physical movement; it was a conduit through which his very flesh, bone, and spirit could absorb and channel mana without the need for external augmentation.

This fusion allowed for a greater level of mana control and internal strength than he had previously believed possible. His mana pathways no longer felt like a separate system coursing through his veins but had integrated with his muscle fibers, sinews, and bones. His strikes were now fueled by his very essence, each attack a seamless blend of physical strength and mana energy.

Merlin's internal refinement reached deeper levels. As he focused on the fists, elbows, knees, and shins, he realized that these were not just weapons, but also the critical junctures where his body's mana pathways converged. These points in his body were directly tied to the elemental energy he could draw from the world. By refining his body, he was also cultivating a deeper connection to the world's elemental forces, allowing him to control not just his strength, but the very elemental mana coursing through him.

In his practice, Merlin began experimenting with the mana channeling at these key points. By channeling the power of the fists through his knuckles, the elbows through his joints, the knees through his legs, and the shins through his lower limbs, he could redirect and focus his mana in more specific and precise ways. Each body part was no longer merely a weapon in combat, but a refined vessel for powerful mana.

What he had learned was that True Demon body refinement involved not just strengthening the body, but perfecting the balance between body and mana. This harmony allowed the body to become infinitely stronger, not by external enhancement or mana augmentation, but through an internal transformation that melded the two into a single entity. As his understanding deepened, he realized that, by cultivating his body this way, he was no longer simply fighting with his body—he was becoming one with the power he wielded.

Merlin's body had become the perfect vessel for mana, capable of channeling, controlling, and unleashing it in a way that human body refiners using Augmentation techniques could not achieve. This revelation ignited something within him: a new path forward, one where true refinement was rooted not in external magic but in the power of the body itself.

With this new insight, Merlin knew that his next step was to continue to hone this connection, pushing the limits of his body and mana until both were perfectly synchronized. This insight would be the key to reaching the next stage of his cultivation—a true mastery of both body and mana, an art far beyond the scope of traditional body refinement techniques.
