Isekai Adventure in the Dimensional Cube

"Boom!"

In the courtyard, a tree suddenly ignited and burst into flames.

This was due to a large amount of heat continuously spreading throughout the courtyard.

The atmosphere gradually distorted, and flowers, plants, and trees suddenly caught fire. Even the ground and surroundings seemed to melt under the astonishing heat, gradually losing their original shape, dissolving like butter.

"Reiger, Reiger Brillhaut!"

Rengoku Kyoujurou couldn't help but call out to Reiger.

There was no helping it, the surrounding temperature had become so high that even Rengoku Kyoujurou, the Flame Pillar, was sweating profusely.

Not to mention Kochou Shinobu, whose hair in front of her forehead was almost completely wet, and her clothes were soaked with sweat, clinging tightly to this Pillar of Insects, unexpectedly outlining a fine body curve.

But after the voice of Rengoku Kyoujurou rang out, the heat that had been relentlessly emitting in the courtyard suddenly paused.

Subsequently, the heat began to dissipate, the high temperature started to fade, and the area around Reiger no longer displayed any abnormalities. Only the burning trees and the charred marks on the ground told others that everything that had just happened was real.

"Whew—"

Standing in the courtyard, Reiger seemed to release a breath he had been nurturing as he opened his eyes.

In his eyes, a flaring fire-like, bright light-like gleam flashed by.

"Are you all right?"

Reiger then approached Rengoku Kyoujurou and Kochou Shinobu with a calm expression.

The two Pillars shook their heads, still appearing heavily sweaty, but it seemed like they were mostly unharmed.

Looking at Reiger, their eyes were filled with an unusual brilliance, containing unspeakable astonishment.

"That was really a terrifying burst of heat," Rengoku Kyoujurou asked Reiger, "Young Master Brillhaut, did you succeed?"

Upon hearing this, a smile finally appeared on Reiger's calm face.

Seeing this smile, how could the two Pillars not understand?

"It appears Young Master Brillhaut has succeeded, congratulations."

Kochou Shinobu, with her beautifully charming smile, offered her congratulations.

"Thank you."

Reiger responded, his tone carrying a hint of melancholy.

Indeed, it was a cause for celebration.

Three months, nearly a hundred days of reckless attempts, enduring endless pain and torment, he had finally succeeded.

Reiger's previous hypothesis had been completely confirmed.

"Inhale—exhale—"

Reiger took a gentle breath, drawing a large amount of oxygen from the atmosphere into his lungs, then circulating it throughout his body.

In that second, a revolutionary change occurred within Reiger's body.

Every cell in his body became active.

Each of his internal organs seemed to activate, radiating heat.

His blood flowed swiftly, mixing with the Magic Power suddenly emanating from deep within his body, surging throughout his entire body.

At this moment, Reiger could clearly feel that his body's capabilities had undergone a tremendous enhancement, so much so that he felt as if he had activated the "Wind Spirit Swift Walk".

This was the evolved Sun Wheel Breath, a breathing technique that amalgamated focused breathing and the sword skills of the Akasha Continent.

It perfectly realized Reiger's concept, not only spreading the enhancement effect of focused breathing to every part and each cell of his body but also incorporating the vast magic power within his body into the bloodstream to boost the enhancement effect.

It also embodied the effects of Akasha Continent's sword skills; each use, each practice, enabled the continual absorption of activated Magic Power, permanently enhancing personal strength.

Capable of increasing power in battle and aiding growth in daily life, Reiger's original concept had been fully realized.

"Now, once I use the Sun Wheel Breath in battle, the enhancement in capabilities must not be less than when I used 'Wind Spirit Swift Walk', right?"

"Having fused the breathing techniques and sword skills of two worlds, the Sun Wheel Breath has now become a high-level sword skill of the Akasha Continent, likely not weaker than the Holy Dragon Sword Skill."

"My current strength…"

Reiger felt it for a moment, roughly formulating some ideas in his mind.

"Can definitely undertake challenges beyond my level."

That's exactly it.

This was different from before.

Previously, Reiger needed to use the exceptional magic, "Wind Spirit Swift Walk", enduring great physical strain just to have the ability to challenge beyond his level.

Otherwise, he would have to reach the limits of his current level, attaining the full-power SSS stage so he could rely on the astonishing potential accumulated over several levels and several combat development abilities to undertake challenges beyond his level.

But now, none of these were necessary.

The enhancements brought by the evolved Sun Wheel Breath were comprehensive, requiring neither physical strain on Reiger's body nor reaching the limit of his current level.

The current Sun Wheel Breath alone was enough to give Reiger the steady capability to combat across one level without any adverse effects.

Just based on this alone, the importance of the current Sun Wheel Breath to Reiger had completely surpassed that of the additional magic "Wind Spirit Swift Walk".

Of course, the benefits that Reiger gained from the evolved Sun Wheel Breath were far more than this.

Apart from the effects brought by the new breathing technique, the process of researching this breathing technique also induced two changes in Reiger.

The first change came from the divine grace.

Reiger's mind involuntarily conjured up a range of ability values.

......

Reiger Brillhaut

Lv.5

Strength: D570 → SSS1303

Endurance: D555 → SSS1300

Dexterity: C611 → SSS1385

Agility: C637 → SSS1393

Magic Power: C632 → SSS1399

Light Armor: F

Swordsman: F

Magic Guide: G

Skilled in Combat: I

...

These were the ability values Reiger had just opportunistically updated.

After three months of putting everything on the line, Reiger had finally reached his current level's limit, reaching the all-powerful SSS stage.

Though at first glance, it seemed Reiger was merely trying to develop new breathing techniques over these three months without undergoing any rigorous training, one must not forget that Reiger's growth was enhanced in a special way.

The effects of "Fool's Obsession" are clearly stated in the skill's description—

· The deeper the obsession, the stronger the effect.

· Effect greatly enhanced when crossing dangerous situations.

Undoubtedly, Reiger's actions over these three months perfectly triggered these two effects.

Even if he was in extreme pain, he continued persistently, developing the Sun Breath technique without concern for safety, actions that could definitely be considered "obsession" and "crossing dangerous situations."

Thus, Reiger's growth accelerated rapidly, successfully reaching the current level's limit, the all-powerful SSS stage.

However, this was not the change Reiger considered significant.

The growth in ability values was expected and not worth mentioning as a significant change.

The real change in Reiger's divine blessing lay behind the three skills, "Fool's Obsession," "Endless Vista," and "Self-redemption."

There, a new skill had emerged.

...

"Sun Wheel Pioneer"

· Spiritual being.

· Light and heat magic effects doubled.

· Resistance to light and heat, freezing, and dark forces.

· Special attack ability against evil-natured entities.

...

Yes.

Reiger had awakened a new skill.

"Sun Wheel Pioneer"—the emergence of this brand new skill meant that Reiger's previous notion of turning himself into the sun was no longer just a pipe dream.

Although he had not turned himself into a sun, he seemed to have turned himself into a sprite.

Not the kind of sprite from the Earth Mistake World that could become a magical race, but one born from nature, considered a part of nature itself.

Reiger was still human, but due to the effect of "Sun Wheel Pioneer," his constitution seemed to have transformed into a being of spiritual nature, acquiring traits similar to those of a sprite.

Moreover, a sprite born from the sun.

What kind of changes this spiritual constitution would bring, Reiger was not yet clear, only able to leave it for future exploration.

But at least, from the other effects of "Sun Wheel Pioneer," this skill was definitely extraordinary.

The doubling of light and heat magic effects meant that light and fire-based magic in Reiger's hands would have doubled the power, greatly strengthening spells like "Simultaneous Fire Spear" and "High-level Victory Sword," which were fire-based area annihilation magic.

Having resistance to light and heat, freezing, and dark forces meant that Reiger would no longer fear high temperatures or low temperatures. Whether it was fire or ice magic, the damage inflicted on him would be greatly reduced; even dark forces would no longer pose a significant threat to Reiger.

And having special attack ability against evil-natured entities made this effect even more precious.

This meant that if Reiger faced enemies with evil attributes in the future, he would have a restraining effect on them.

For instance, the demons of this world, Reiger might be able to kill them without even using the Sun Wheel Blade.

There were also the creatures that dwelled in underground cities from the Earth Mistake World, many of which were of the evil type.

Furthermore, individuals like the previous Demon Swordsmen who employed evil sword techniques, if they faced Reiger, they could be overwhelmingly restrained.

This effect was significant enough to make Reiger feel exhilarated.

The second type of change came from Reiger's senses.

Reiger lifted his eyelids and looked at Rengoku Kyoujurou and Kochou Shinobu in front of him.

Under his gaze, the bodies of Rengoku Kyoujurou and Kochou Shinobu gradually became transparent, so transparent that Reiger could see inside their bodies at a glance.

He could see their hearts and internal organs.

He could see their muscles and flesh.

He could even see the blood vessels in the lungs of Rengoku Kyoujurou and Kochou Shinobu flow and judge their next actions based on these signs of flow and muscle contraction.

"Is this what it means to see through the world?"

Reiger silently thought to himself.
