Second Dimensional Travel

Frenzel Family Main Residence, Riezel's Room.

After leaving the reception room, Riezel went straight back to his temporary room and locked the door behind him.

Just moments ago, he had told Yuri that he wanted to rest in his room for the day, without needing food or being disturbed, and if she wanted to discuss anything with him, they could do it tomorrow.

Yuri readily agreed, advising him to rest well and take care of his injury, assuring him that there was no rush to address anything until he was fully recovered.

Evidently, she assumed his injury from yesterday hadn't fully healed yet, which was why she didn't question his request.

However, since his injury had already completely healed, it was naturally impossible for him to go back to rest and recuperate. Having decided to embark on dimensional travel again toward the goal of becoming a Sword Saint, he didn't want any further delays.

Besides, now that Yuri's marriage arrangement matter had been resolved and they had dealt with the situation in the royal capital, including the conclusion of the War Festival, there shouldn't be any other important matters to worry about in the short term.

'Even if something important were happening, one day without me wouldn't be a problem, right?'

No matter how much time passed in other worlds, only one day would have passed in this main world after all. In just one day, he couldn't believe anything serious would happen.

Nevertheless, considering safety, Riezel decided to take some precautionary measures.

"O Word Spirits - fulfill my wish."

"Veil of the woods - my name is Alf."

"Veil Breath."

Riezel cast a magic.

In the next moment, a layer of greenish magic membrane appeared around his body, resembling a cloak, enveloping him.

The magic he cast was one of the three defensive magic taught by Riveria to him, capable of resisting attacks.

Among the three defensive magic taught by Riveria, this magic ranked second, with outstanding protective capabilities, far more reliable than the enhancement of END by Raumure.

Since Riezel had poured most of his mind into this magic, as long as he wasn't repeatedly attacked, it should last for a long time and continue to be effective until he returned from dimensional travel.

During the previous dimensional travel, he had no means to protect his body left behind in the main world while his consciousness journeyed to other worlds. At that time, he was desperate to gain power and couldn't think too much, hastily embarking on dimensional travel to the world of Danmachi.

But this time, since he had enough power for self-protection, he couldn't leave his body in the main world defenseless during dimensional travel. If it weren't for him being at the Frenzel family's place, he even considered using his strongest defensive magic.

Unfortunately, this strongest defensive magic was a barrier magic. If he used it, it would undoubtedly envelop the surrounding area and be noticed by others, causing significant disturbance.

Reluctantly, Riezel had to abandon that idea and resort to using Veil Breath for protection.

After completing these steps, Riezel also set up some simple magic at the door lock and other places, which would notify him if anyone opened the door or entered the room after he woke up.

Yuri had taught him these simple magic.

Surprisingly, this setup came in handy.

'Before doing dimensional travel, let's update my status.'

Riezel took out Loki's blood from the storage space and let a drop fall onto his forehead. Soon enough, a faint aura emanated from his back, forming floating sacred texts, one after another.

Before long, his status was freshly updated.

...

...

The last time he updated his status was back in the royal capital.

After leaving the royal capital, Riezel first rode in a horse carriage for a day to reach Trantia, then took a three-day ship ride to the Frenzel territory, and spent another week preparing before the War Festival began. When he added up these scattered moments, it had been about two weeks since his last status update.

In less than two weeks, his total basic ability proficiency had increased by over 1500. In a world without dungeons or monsters to defeat, this was quite impressive.

Of course, the most pleasant surprise was that three development abilities had been upgraded by a rank.

'Well, I've been practicing my swordsmanship and magic lately, so both the Swordsman and Mage development abilities should show some growth...'

As for the increase in rank in Lightweight, it seemed to have occurred because he hadn't been carrying heavy loads in training or combat.

As for Battle Adept, it didn't change at all. Considering it was closely related to combat, and he had only been in a few battles since returning to this world, it was normal that it hadn't progressed.

Overall, Riezel was quite satisfied with his growth this time. Now, he could face the upcoming dimensional travel in the best possible condition.

After finishing his status update, Riezel sank his consciousness deep into his mind, focusing on the transparent cube slowly rotating within.

But first, he checked his remaining dimensional energy.

[Dimensional Energy: 40]

When he returned to this world, Riezel had 23 units of dimensional energy left. Now, after about half a month, it had accumulated to 40 units.

A random dimensional travel required 30 units of dimensional energy, so his remaining dimensional energy was more than enough.

'Dimensional Magic Cube, activate the dimensional channel.'

Riezel instructed the transparent cube in his mind.

Before long, just like the first time he performed dimensional travel, the transparent cube in his mind began to rotate.

[Instructions accepted, starting the activation of the dimensional channel.]

[Sufficient energy, beginning the construction of the dimensional channel.]

[Built successfully.]

As the transparent cube rotated, each grid separated from the main body, disintegrating into countless transparent cubes. They spun and intersected with each other, ultimately forming a channel that extended to the depths of the consciousness sea, disappearing into the void.

[Finished with the opening of the dimensional channel, the information collection has been completed.]

[Searching information highly compatible with the world on the other side of the channel from the user's memory, now arranging it.]

[Successfully arranged.]

[Connected World: Demon Slayer (Kimetsu no Yaiba)]

[Time Scale: 1:180]

[Dimensional travel is the descent of consciousness, in which the user's consciousness is materialized in another world. Death of the consciousness after materialization will not affect the user, but the dimensional travel will end at the time of death. Please be careful.]

In the split second following the successful construction of the dimensional channel, the Dimensional Magic Cube also relayed the message of this dimensional travel to Riezel's mind, which he received instantaneously.

Riezel was immediately taken aback.

'Demon Slayer?'

Riezel's memories were triggered instantly, recalling the original work's worldview, settings, plot, and important characters one by one.

At this moment, his exceptional memory proved invaluable, allowing him to smoothly recall most of the information about this world. It couldn't be said that there were no missing parts, but at least the important parts were remembered.

This was a world set in the Taisho period.

The Taisho period spanned from July 30, 1912, to December 25, 1926—a total of fifteen years.

For Riezel, who had lived until after 2020 in his previous life, it was an era over a hundred years ago.

In that era, there existed a group of swordsmen fighting in the shadows against monsters tracing back to a thousand years ago, monsters known as 'Demons'.

These were not like the monsters from the world of Danmachi, banished by humans into the dungeon, unable to return to the surface. Rather, they were humanoid creatures that fed on humans to survive.

Demon fed on humans, gnawing on flesh, taking lives without mercy, utterly ruthless, causing numerous tragedies.

Most people were unaware of their existence.

Those who knew either perished by their hands or suffered greatly, having experienced firsthand the tragedies caused by demons. Because of this, these people spontaneously formed a group, united, wielding swords, determined to exterminate all demons in the world.

This was the main story of the world of 'Demon Slayer', revolving around the struggle between 'Demons' and 'Demon Slayers', composing a tale that was both exciting and tragic.

'If it's this world...'

Riezel felt a mix of excitement and concern.

Excitement, because this world had a power system that intrigued him.

Concerned, because while this world had demons and other creatures to challenge, if he remembered correctly, demons weren't exactly abundant. He couldn't simply go about killing them as he did in Danmachi to rapidly grow stronger.

'Besides, the time ratio is different than before? 1:180?'

In other words, Riezel could spend a total of six months in the world of Demon Slayer, a full half-year.

Half a year seemed long, longer than the time he'd spent since transmigrated, but considering the situation in that world, whether he could accumulate enough exploits to level up within this half-year was still uncertain.

Fortunately, there were still some things worth exploring in that world.

Thinking about the power system of that world, a few ideas flashed through Riezel's mind.

'Maybe it's worth a try...'

If his ideas could be realized, he might gain an entirely new power.

'Even if it fails, six months of effort will surely result in some growth, not a loss.'

With that mindset, Riezel reaffirmed his determination, lay down on the bed, and closed his eyes.

After a while, his breathing steadied as if he had entered the realm of dreams.

However, his consciousness was no longer in this world; it had traveled through the dimensional channel constructed in his mind to another world.

The entire room immediately quieted down, leaving only the sound of Riezel's breathing, creating a peaceful atmosphere.
