Isekai Adventure in the Dimensional Cube

The town, Butterfly House.

It was a small courtyard that seemed quite cozy.

The scenery within the courtyard was beautiful, not only were flowers and plants grown, but also many precious medicinal herbs were cultivated, the fragrance of which directly attracted a large number of butterflies. The butterflies danced gracefully, making the scene delightful to behold.

The location of the courtyard was also quite remote, which seemed to have spared it from disaster, avoiding destruction due to ghost attacks.

However, when Reiger arrived here, he still found that there were many injured people, filling each room of the small courtyard with moans and wails of agony, leaving no one to appreciate the pleasing scenery.

"Sorry! Excuse me!"

"Make way! Injured coming through!"

"Quick, bring the stretcher over!"

One after another members of the Hidden brought in the injured into the Butterfly House. Several young girls in white dresses also ran out of the Butterfly House, directing the members of the Hidden to move the injured inside while running back and forth with medicine boxes, apparently always engaged in treatment.

This busy scene made many people bustling about profusely sweating start to lament their hardship.

"There are too many injured, we simply can't take care of them all!"

"At a time like this, Lady Shinobu is also injured, she simply can't treat the injured!"

"When will Lady Shinobu get better?"

"Alright, enough talk, focus on your work!"

"Yes..."

Conversations like this occasionally echoed from the people passing by, letting Reiger understand just how chaotic the Butterfly House had become without Kochou Shinobu.

Thus, Reiger didn't disturb the people here and went straight into the courtyard towards the room where Kochou Shinobu stayed.

The location of the room was revealed by a little girl who hurriedly passed by, who was currently too busy to care about who Reiger was or what he was here for, saving him a lot of trouble explaining.

Soon, Reiger arrived at a relatively quiet room, pushed open the door and entered.

The room was very ordinary.

The room was still decorated cozily, not at all resembling a sickroom.

Kochou Shinobu lay on the bed at the far end, deep in sleep.

Reiger closed the door behind him as he approached the bed and looked at Kochou Shinobu.

Kochou Shinobu appeared to have received preliminary treatment already; her bloodstains had been cleaned, her clothes changed to a sick gown laying under the covers, oblivious to Reiger's arrival.

Her complexion was pale, her lips devoid of any color, her hair had been untied, spreading over in long strands, making her look much more fragile compared to her usual self.

Faintly, through the gaps of the quilt, Reiger could see Kochou Shinobu's body wrapped in several blood-stained bandages, clearly showing how severe her injuries were.

"You look much worse now than when I was brought in,"

Reiger muttered to himself, then extended his hand and placed it on Kochou Shinobu's forehead.

Perhaps due to extreme weakness, Kochou Shinobu's body temperature seemed very high, indicating a fever.

Reiger frowned, then began chanting a spell.

"[Healing drop, tear of light, Permanent Holy Sanctuary, summon the medicinal melody here]."

"[Three hundred sixty-five melodies, the healing calendar that will save all beings]."

"[Next, come forth, dispel the evil]."

"[Bury the wounds, send away the sickness]."

"[Curse dispatched to the netherworld, send forth the pivot of light]."

"[In the name of the gods—be healed by me]."

A pure white magic array suddenly expanded from beneath Reiger's feet, covering the bed.

"[Diya Flatel]."

Reiger completed the chant, casting the highest level of healing magic from Earth Mistake World.

The next moment, light rained down like a shower, falling upon Kochou Shinobu.

Under this illumination, Kochou Shinobu's pale complexion visibly recovered, her colorless lips gained some color, and even the temperature of her body seemed to gradually return to normal, stabilizing the breathing of the severely injured Pillar.

Reiger spared no effort in expending his spiritual power, maximizing the effect of [Diya Flatel], which resulted in an extraordinarily surprising healing outcome.

At least compared to Amide, the Lv.2 Battlefield Saintess who claimed to support an entire battlefront by herself, Reiger, who had reached the limit of Lv.5 and whose "Magic Power" far surpassed hers, the effect of liberally releasing this magic was, naturally, quite predictable.

In about ten seconds, Kochou Shinobu seemed to have fully recovered.

Although Reiger couldn't see the state of the wounds beneath the bandages, those injuries must have healed completely by now, right?

Once finished, Reiger stopped using the magic, preparing to move his hand away.

However, just as Reiger was about to remove his hand, a hand suddenly reached out and grabbed it.

"Sister..."

Kochou Shinobu tightly held the hand that was on her forehead, as if finding warmth and recalling memories unconsciously, she murmured in her sleep.

As she murmured, a tear trickled from the corner of her eyes.

"..."

Seeing this scene, Reiger fell silent.

In contrast, Kochou Shinobu gripped Reiger's hand tighter and tighter, as if she didn't want him to leave.

Of course, if he wanted to break away, it would still be quite easy for Reiger.

But he didn't do it.

He just stood by the bed, keeping his hand on Shinobu's forehead, quietly watching Shinobu sleep beneath the covers.

This gesture lasted for an indeterminable amount of time.

"Uh…"

Until at one moment, accompanied by a low, vague groan, Shinobu, lying in the bed, struggled to open her eyes.

"Are you awake?"

Reiger spoke softly.

"…Hmm?"

Shinobu's mind seemed a bit fuzzy, unable to immediately grasp what had happened.

After a while, Shinobu's pupils began to focus. She saw Reiger standing beside the bed, saw herself lying there, and naturally, she also saw her hand tightly clasped with Reiger's.

At that moment, Shinobu fell silent.

Reiger didn't rush to speak; he continued to watch Shinobu quietly.

After a long pause, Shinobu finally spoke softly.

"In this situation, can I ask you to take responsibility?"

That comment almost made Reiger roll his eyes.

"Taking responsibility isn't possible, but paying money could be considered."

Reiger pulled away from Shinobu's hand.

"That's really too much."

Shinobu complained, not sure whether she was referring to Reiger's action or his statement.

"How do you feel?" Reiger asked, "There shouldn't be any pain, right?"

"…Indeed, there isn't." Shinobu sat up, glanced at her body, and said in surprise, "How long have I been asleep?"

It was no wonder Shinobu would have this question.

She hadn't forgotten how severely wounded she had been by the hands of Upper Moon Six.

Those were injuries so severe she could have died on the spot without any issues. To fully recover would typically require at least two to three months, according to Shinobu's professional judgment as both a physician and a pharmacist.

But now, she felt as though all her injuries were healed, experiencing only a slight discomfort from the bandages wrapped around her body, without any other discomfort.

This made Shinobu suspect whether she had simply slept for two or three months and recovered from all her injuries during that time.

"You've been asleep for one night." said Reiger quickly dispelling the doubts in Shinobu's mind, "The attack by the three Upper Moons on the town just happened last night."

"One night?"

Shinobu was instantly surprised.

Only one night had passed?

She had completely healed from such severe injuries in just one night?

How could that be possible?

Thinking this, Shinobu soon thought of something.

"Did you do something to me?"

Shinobu stared intently at Reiger.

"That really is a phrase that can cause misunderstandings." Reiger said calmly, "I didn't do anything, you know?"

"Liar." Shinobu didn't believe him even for a second, saying, "Besides His Majesty, who else could accomplish such a thing?"

It was known that for the past three months, Reiger had more than once defied common sense.

For the evolution of the Sun Breathing, Reiger desperately tried, barely surviving one moment and then bouncing back full of vigor the next, continuing his normal training.

This had made Shinobu suspect in the past that Reiger might have some special kind of physique.

In this world, some individuals naturally possess very special physiques.

For example, Tanjirou has an exceptionally sensitive sense of smell that can even detect changes in people's emotions, an almost unscientific ability.

Zenitsu and Inosuke as well, one possessing extraordinary hearing and the other remarkable tactile sense; these are also special physiques.

There are also several individuals among the pillars of the Demon Slayer Corps who have special physiques.

Kyoujurou, the Flame Pillar, was born with greater strength than ordinary people, therefore, he has always seen it as the duty of the strong to protect the weak.

Uzui Tengen, the Sound Pillar, who was a ninja before joining the Demon Slayer Corps, has a certain degree of poison resistance and great strength, not inferior to Kyoujurou, with even better speed, unmatched across all the pillars.

Kanroji Mitsuri's muscle density is eight times that of an ordinary person, allowing her to significantly enhance her defensive power when tensing her body, making her stronger than most men.

And then there's Shinazugawa Sanemi, who possesses a rare kind of thin blood, which is highly attractive to demons, making them intoxicated just by smelling it.

These are all special physiques.

Reiger's anomalous healing ability had been considered by Shinobu as a special physique in the past.

But now, it seemed it wasn't just a simple special physique.

Anyway, Shinobu didn't believe that she could recover from such severe injuries overnight without Reiger doing something.

"Can you please tell me? His Majesty~~~"

Shinobu then smiled and moved her face very close to Reiger's.

Looking at this face that was super close to his own, not only fair-skinned but also beautiful, Reiger was at a loss for words.
