Isekai Adventure in the Dimensional Cube

"This sword…"

The moment Reiger grasped the newly formed Hermit, a look of surprise appeared on his face.

It couldn't be helped.

"So heavy, and so hot."

The Sun Wheel Blade he held was not only as heavy as a war hammer, but its surface temperature was extremely high, likely having reached the boiling point of water under normal conditions, which is 100°C.

Such a sword, a normal swordsman wouldn't even manage to hold the hilt.

"This weight, with this sword in future use, I fear that my 'light equip' won't be of much effect anymore."

Reiger sighed and lowered the sword.

"Tss…"

As he lowered it, before the tip even touched the ground, the ground started to hiss and a small black spot appeared.

"Is the blade even hotter?"

Reiger was taken aback, raised the sword again, and fell into deep thought.

After a while, Reiger created a piece of iron using Structural Magic and tossed it into the air.

Watching the iron block fall, Reiger slashed at it.

"Tss!"

The next second, the Hermit's blade cut through the iron block like slicing through butter, splitting it in half. The pieces fell to the ground, their broken edges still glowing red and smoking.

This made Reiger excited.

"Good grief, is it that sharp?"

No, not sharp.

The reason the Hermit could so easily slice through the iron block was due to the high temperature it contained.

With such high heat, the Hermit's cutting power became frighteningly formidable, it was more like burning through the iron rather than cutting it.

Such high temperature would normally affect the sword's blade, but due to the Hermit's indestructibility attribute, the sword miraculously maintained its characteristics and properties.

"The performance and power of this sword, definitely surpasses the Fool's."

First grade special armament!

This is absolutely a first grade special armament!

Reiger had not expected the new weapon he had forged with magic to achieve such perfection!

"Is it because I triggered a hypothetical attribute while using magic? Or did the Hermit's sword meld with the essence of the original stones of the orangutan scarlet iron and the orangutan scarlet ore in some chemical reaction?"

Reiger was unsure.

But he was clear, he might have acquired an exceptional Sun Wheel Blade.

"Let's test the sword."

Reiger couldn't resist, took up the sword, and left the Rengoku family's home.

......

Behind the Rengoku family mansion, there was a hill that looked like the family's own mountain, forming a large expanse of forest.

As Reiger entered the forest, he observed his Sun Wheel Blade.

At this moment, the Sun Wheel Blade was changing color.

This was a characteristic of all Sun Wheel Blades.

Sun Wheel Blades, also known as the Color-Changing Blades, change colors according to their owner, reflecting the breath type best suited for the user.

For those suited for Water Breath, when they grip the Sun Wheel Blade, its blade turns blue.

Thunder Breath is gold.

Flame Breath is red.

Wind Breath is green.

Rock Breath is gray.

For someone like Rengoku Kyoujurou, his Sun Wheel Blade's blade was red, while for Tanjirou it was black.

A black blade is a very rare type of Sun Wheel Blade, and no one knew which breath type suited the swordsman whose blade turned black.

But Reiger knew that users of the black blade were highly compatible with Sun Breath.

Because, Tsukiguni Yoriichi's Sun Wheel Blade was a black blade, its blade akin to obsidian, only turning red during battle.

And Reiger's Sun Wheel Blade, under his watch, slowly turned black.

Yes, Reiger's Sun Wheel Blade was also a black blade.

However, the red patterns on his black blade did not disappear; instead, they became brighter and more vivid.

The blackness of the blade was extremely deep, like staring into a bottomless abyss, making it feel like one was gazing into a black hole.

"Breathe—"

Reiger adjusted his breathing and suddenly slashed with his sword.

"Boom!"

A massive fire exploded.

In the terrifying heat, flames suddenly descended from the sky as Reiger slashed down, striking the ground and shattering it on impact.

The fire swept through, ravaging the forest and instantly igniting countless trees, turning the surroundings into a sea of flames.

"[Disintegrate]."

Reiger immediately used disintegration magic, causing the Red Wave to roll through the forest like a hurricane, turning the flames into nothingness.

However, the scene after the wildfire still remained here.

Smokey fumes rose, and charred marks were scattered across the ground and on the half-burned trees, making the area resemble the aftermath of a fire disaster.

Reiger then landed on the ground, looked around, and then at the Sun Wheel Blade in his hand, wrapped in flames, and gradually smiled.

"The power is indeed remarkable, and it matches well with the Sun's Breath."

Using this blade, although Reiger's "Light Gear" could not be fully utilized, it did enhance his attack power and explosive force.

"From now on, the Hermit will be the exclusive weapon for Sun's Breath usage."

With this thought, Reiger began to test other capabilities in the forest.

However, after some trials, Reiger stopped and furrowed his brow.

There was bad news and good news.

The bad news was that he couldn't use magic while using Sun's Breath.

No, it should be said that he couldn't use additional magic like Wind Spirit Swift Walk.

Perhaps because the evolved Sun's Breath activated the vast Magic Power within Reiger, incorporating it into his bloodstream, the flow of this part of the Magic Power was affected by the magic of Wind Spirit Swift Walk. Or maybe because the properties of Sun's Breath and Wind Spirit Swift Walk didn't match, if he used both at the same time, the flow of Magic Power in Reiger's body would become chaotic, causing problems in the circulation of Sun's Breath.

Thus, Reiger could not only not use direct additional magic like Wind Spirit Swift Walk on himself, but he also couldn't use protective magic like Lamu to enhance his own "stamina" and "agility."

The rest of the magic was not affected, as long as it wasn't used to enhance his own abilities and directly affect his body, it wouldn't influence the Magic Power cycle of Sun's Breath.

This meant that once Reiger used Sun's Breath, he could no longer stack other enhancement magic, support magic, and auxiliary magic that had an amplifying effect.

The good news, however, was that Reiger discovered that using Wind Spirit Swift Walk simultaneously with Wind's Breath, one of the five fundamental breathing styles, not only strengthened the magic's effect but also dramatically reduced the burden on his body.

"Is it because Wind's Breath and Wind Spirit Swift Walk share similar properties, and they are exceptionally compatible?"

Reiger figured out the reason.

Wind's Breath not only amplified the effect of Wind Spirit Swift Walk but also, because using the breathing technique enhanced physical abilities, the body's endurance greatly increased. Thus, the burden brought by Wind Spirit Swift Walk was completely borne by the body strengthened by Wind's Breath, significantly reducing the side effects.

Reiger felt that the similarity in their properties also played a role, so the burden of Wind Spirit Swift Walk on users of Wind's Breath wasn't as severe as usual.

Otherwise, relying solely on the physical abilities enhanced by the "Wind Spirit Swift Walk" could hardly withstand the strain brought by such an exceptional piece of summoning magic.

This was an unexpected pleasure.

"Although the Sun Breathing and 'Wind Spirit Swift Walk' cannot be used at the same time, I might be able to fight in two different modes in the future," he said.

Reiger immediately had an idea.

"The Hermit is to be used with Sun Breathing, allowing me to steadily fight across one level, making me strongest in this mode, capable enough to compete with mid-to-lower Lv. 7s."

"The Fool, on the other hand, matches well with 'Wind Spirit Swift Walk', maximizing the 'Light Equip' effect and enhancing both 'Agility' and 'Dexterity', which perfectly complements the 'Wind Spirit Swift Walk' as it also relies on speed and agility. Combined with Wind Breathing, I should possess a speed far surpassing the ordinary Lv. 7."

If he used only 'Wind Spirit Swift Walk', the current Reiger should be able to comfortably defeat the limit of Lv. 6, and he wasn't far from the combat power of Lv. 7.

And with Wind Breathing amplifying the effect of 'Wind Spirit Swift Walk' and mitigating its side effects, Reiger should be able to wield power rivaling Lv. 7.

In this state, using the Fool to battle, and maximizing the 'Light Equip' effect, considering only 'Dexterity' and 'Agility', an ordinary Lv. 7 could never match Reiger.

Furthermore, Reiger could also use 'Lamu' to further enhance his 'Agility', making his capability in other areas just enough to cross the threshold into Lv. 7, but 'Agility' would significantly exceed this threshold, reaching the top of Lv. 7.

Thus, Reiger could completely choose which mode to use depending on the opponent he faced.

"Using Hermit as the main weapon, employing Sun Breathing for a strong offensive approach," he said.

"Using Fool as the main weapon, utilizing Wind Breathing along with summoning and protective magic for a rapid attack strategy," he added.

"Hmm, this feels doable."

Upon this realization, Reiger took out the Fool from his storage space and held it in his hand.

As his mind moved, a character instantly appeared on the hilt of the Fool—'Fool'.

This character was not added for aesthetic appeal or as a sword inscription but rather to prevent it from being lost.

Both the 'Hermit' on the Hermit's hilt and the 'Fool' on the Fool's hilt were marks used for casting summoning magic.

As long as these marks remained intact, Reiger could summon these two weapons to his hand through magic.

Therefore, even if they accidentally slipped from his grasp, Reiger need not worry about losing them or being disarmed.

Naturally, this was one of the many minor magics taught by Miss Yuri, still seemingly unobtrusive yet exceedingly practical.

After doing all this, Reiger stored the Fool back into his storage space, keeping the Hermit in his hand.

He planned to craft a sheath for the Hermit, as the old sheath of the Hermit's sword didn't fit anymore.

However, considering the Hermit's blade was very hot, crafting a sheath to store it wouldn't be easy.

But there was no choice; difficult or not, it had to be done.

Now, Reiger was indeed very fond of this Sun Wheel Blade.
