Isekai Adventure in the Dimensional Cube

Let's set aside the matter of black tea for now.

Despite the shockingly sweet black tea, Reiger was truly grateful for the kindness Yuri had shown him.

She not only saved his life but also agreed to let him stay and temporarily protect him. For both emotional and rational reasons, Reiger knew he had to remember this favor.

Therefore, Reiger no longer hurried to leave; he stayed in the pavilion, chatting with Yuri.

Reiger found that Yuri seemed to really enjoy chatting with him.

Or rather, Yuri liked to have someone she could talk to freely, and it just happened to be Reiger.

Ever since Reiger was still healing, Yuri would often come to see him, sometimes discussing serious matters, sometimes simply chatting idly. But no matter the topic, Yuri always seemed very happy.

If not for that, why would this Marquis of the Ginas Kingdom, a famous tactician Magician on the Akasha Continent, personally visit and talk to Reiger?

With Yuri's status, even if she had saved someone and brought them back to heal, it was not necessary for her to personally visit to offer comfort. Simply ordering her servants to take good care of Reiger would have been more than enough.

Therefore, Reiger could feel Yuri's kindness, and he was willing to reciprocate by chatting with her and alleviating some of her boredom.

Perhaps, at the beginning, Yuri was only willing to meet him because the original owner of the body had the potential to become a Tactical Level Magician or even a Strategic Level Magician?

But as they interacted more, the frequency of Yuri's visits to Reiger skyrocketed, and now, just sitting together chatting and drinking tea seemed to satisfy her greatly, leaving Reiger clueless about how to react.

But that was the thing—since Yuri enjoyed chatting, Reiger was naturally willing to oblige.

This was also Reiger's way to learn about this world and the Ginas Kingdom.

After all, the original inhabitant of his body was a country bumpkin who had rarely been exposed to the world, with little experience and only a vague grasp of common knowledge, not really clear on the specific details.

In contrast, Yuri, as a noble just below the Duke, the kingdom's chief court Magician, and part of the high society, had an understanding of this country and this continent that others could hardly match.

During the month he spent healing, Reiger also learned much about this world through their conversations, just as now.

Chatting with Yuri was just as beneficial for Reiger, allowing him to understand this world better and learn secrets that others didn't know.

Until—

"Miss,"

A butler-dressed old man approached the pavilion, bowing to Yuri while speaking.

"The young master from the Basolo family has come to visit."

That one sentence wiped the smile off Yuri's face.

"Understood," said Yuri without expression. "Please escort him to the reception room, I'll be there shortly."

"Yes," the butler replied and then withdrew.

It was only after this that Yuri's face showed emotion again, though it didn't look very pleasant.

"What's wrong?"

Seeing this, Reiger asked.

"...It's nothing." Yuri seemed about to say something, but then reconsidered after a moment and said with a sigh, "Sorry, I need to go entertain a guest."

Obviously, it wasn't someone who made Yuri feel welcome.

"It's all right." Reiger was somewhat concerned, but since Yuri didn't elaborate, he didn't press further and said, "Go ahead, I'll be fine on my own."

"That's good," Yuri smiled faintly and added, "You can go back to your room or wander around the estate; just don't leave this villa. You're free to go anywhere you like."

With that, Yuri took a crystal from her chest.

"Here, take this."

Yuri handed the crystal to Reiger.

Reiger examined it briefly, then said with surprise, "Is this a communication crystal?"

"That's right," Yuri replied with a smile. "This is for you. If you need to, you can use it to contact me."

"Is this really alright?" Reiger hesitated. "I remember these things are quite expensive."

Magic crystals were similar to the magical stones of the Earth Mistake World.

They were materials used for making Magical items; by using these materials, various spells could be inscribed into them, and turned into diverse special items that brought convenience to life and many other areas.

The magic crystal Yuri gave to Reiger was one such item, capable of communication.

Such an item was exceedingly expensive and therefore not commonly found among the general populace. Apart from some big merchants who extensively invested for the sake of business convenience, it was typically only the nobility that carried them.

So long as two communication crystals were previously allowed to touch and the magical wavelength of one was recorded by the other, one could converse with the person holding the other crystal regardless of the distance.

This was much more magical than phones or telephones from his previous life.

Even though there was the hassle of needing a previous touch to record the crystal's wavelength (the equivalent of a telephone number), the ability to make calls from anywhere far surpassed the limitations of signal-dependent phones of his former world.

Although the original owner had friendly relations with many nobles, he himself did not have a communication crystal, so Reiger knew full well how valuable such an item was.

However, this seemed to be a minor issue for Yuri.

"This little thing isn't much. I have plenty, and Marilyn has one too. Don't be shy about it," Yuri told Reiger. "It's for the sake of easy contact."

Now that Reiger wouldn't be just lying in bed, he indeed needed a way to reach others.

"This crystal has already been set with my wavelength, and also with Marilyn's. If for some reason you find it inconvenient to contact me, you can reach out to Marilyn."

With these words from Yuri, Reiger glanced at Marilyn.

Marilyn still stood by Yuri's side, her face indifferent, as if she were completely unaware of Reiger's gaze.

"All right, then."

After thinking it over, Reiger finally accepted Yuri's kindness and took the magic crystal.

"By the way," Yuri suddenly seemed to remember something, and said, "if you really find yourself bored, you can also take a look at the library."

As soon as these words were spoken, Marilyn's expression changed.

"Miss."

Marilyn furrowed her brow as if she wanted to say something but was stopped by a look from Yuri.

"What about the library?"

Reiger noticed this and was slightly taken aback.

"Nothing much, don't worry," Yuri said, laughing lightly, "it won't harm you. Of course, whether or not you go is up to you."

Leaving him with those words, Yuri then turned and left.

As for Marilyn, she actually glared at Reiger without a trace, then left with a somewhat aggrieved manner.

Reiger was left alone in the pavilion, watching the departing figures of the young lady and her servant, lost in thought.

"It seems that this so-called library is not a place one can enter casually."

Reiger considered for a while and then decided to take a look.

Just as Yuri had said, she surely wasn't out to harm him, otherwise Reiger would have long since been dead.

Thus, Reiger left the pavilion, preparing to enter the mansion.

However, before entering the mansion, Reiger encountered many people.

He saw that, at the gate a distance from the courtyard, there was not just a luxurious carriage parked, but also many knights arrayed neatly there.

Reiger glanced over and, seeing nothing of interest, entered the mansion.

...

The Franzel family's library seemed to be at the very top of this grand mansion.

It was situated next to Yuri's personal study, not in a secluded position, but when Reiger asked the servants where the library was, they looked at him with surprise and then informed the guard to come over and inquire.

After discovering Reiger was looking for the library with Yuri's permission, the guards exchanged glances before finally directing him to the library.

And before he left, Reiger clearly saw envy, even jealousy, in their eyes.

Afterward, on his way to the top floor, Reiger was stopped by roughly three groups of people, each of whom, upon confirming his permission from Yuri, reluctantly allowed him to go up.

This made Reiger even more certain that the library was indeed a place of great importance.

Strangely enough, for such an important place, there were hardly any people guarding the door.

Reiger looked at the library door with some confusion before advancing to push it open and walking in.

Unbeknownst to Reiger, as he pushed the door, a small magic array briefly appeared on the doorknob.

The magic array flashed momentarily, appearing and disappearing so quickly that Reiger failed to notice the anomaly.

Reiger thus entered the library, and the door closed automatically behind him.

Only then did he look around at the entire library.

It was a very ordinary library.

It was neither large nor small, filled with numerous books, arranged on exquisite bookshelves, yet the air was not saturated with the scent of books.

Reiger approached a bookshelf and picked up one of the books.

At that moment, Reiger finally understood why the people here were so nervous about this library.

Because the books here were all extraordinary.

For example, the book Reiger now held in his hand was titled — "Introduction to Basic Magic."

Yes.

This was a magic book that taught people how to use magic and how magicians should begin their training.

"Are all the books here meant to teach magic, like magic textbooks and the like?"

Reiger's eyes changed as he looked around the library.

This was not just a library.

It was clearly a place for the transmission of magical knowledge!

No, not only of magical knowledge.

Reiger noticed that one of the bookshelves contained books not related to magic, but about swordsmanship instead.

"Swordsmanship?"

Reiger's interest was piqued instantly.

If the original owner's memories were correct, then the sword techniques of this world were quite special.
