Later on, Yuri told Riezel that although his decomposition magic had turned into imaginary control system magic, the imaginary trait might not necessarily appear in other magic.
"Most magicians with imaginary system compatibility only have one or two magic with the imaginary trait that causes unusual changes, while the rest of their magic remains normal." Yuri explained.
She also informed him that this seemed to be related to the compatibility between the user and the magic itself rather than to the magic system. The better the compatibility between the user and the magic, the more likely the imaginary trait would appear in that magic.
Judging from this perspective, Yuri believed that Riezel's compatibility with decomposition magic should be high. Even though his control system compatibility was only second-grade, the compatibility between decomposition magic itself and him was irrelevant to magic system compatibility.
Therefore, Riezel's decomposition magic had become an imaginary control system magic, but the rest of his magic might not necessarily follow suit.
To prove this point, on the same day, Yuri also taught him several kinds of magic.
They included transformation system magic, interference system magic, and structure system magic, not limited to control system magic alone.
It wasn't until then that Riezel realized that although Yuri specialized in the control system, she was not ignorant of magic in other systems.
"Even though my compatibility in other systems is only first-grade, considering their usefulness in battles and daily life, it's beneficial for both me and other magicians to learn some magic from other systems." Yuri explained the reason.
At that time, Riezel was ambushed by people sent by the Basolo family. During the fight, he was subjected to various kinds of interference magic by one of them.
Interference system magic, which could inflict negative statuses and effects on others, generally required another interference system magic to dispel if one got affected.
Another example was barrier magic, similar to the one that enveloped the Frenzel residence.
If someone was trapped with barrier magic, they would need corresponding magic to break free from the barrier constraints. This kind of magic usually fell under the interference system. Because of this, every magician would learn some interference system magic to prevent being secretly attacked and ambushed with this kind of magic.
On the other hand, magic from the structured system could also be handy in many situations.
For example, when facing environments with spreading toxic gas and lacking appropriate protective gear, it would be necessary to use structure system magic to create an emergency gas mask.
While on the move, items like ropes, blocks of wood, knives, or iron could all be created using structure system magic. Since the difficulty of creating them wasn't high, mastering this magic would naturally be a good thing.
Transformation system magic had even more uses. It could start fires, produce water, generate electricity, summon winds, and even repel insects and track targets. Learning these kinds of magic would always be helpful.
Yuri took various factors into account and mastered a variety of magic from different systems, leaving Riezel with the impression that if this woman were stranded on a desert island, she would thrive until a ripe old age without any problems.
Thanks to this opportunity, he learned various kinds of magic from her. Though they were insignificant, they could be useful in times of need. Learning them was quite reassuring and better than nothing.
After learning various kinds of magic from Yuri, Riezel tried each one as she had suggested. True to her words, unlike decomposition magic, none of them turned into imaginary system magic.
Apart from that, the eleven magic he learned from the world of Danmachi remained unchanged, retaining their original effects and appearances.
Currently, among the magic Riezel had mastered, only decomposition magic had transformed into an imaginary control system magic. His other magic had not undergone any changes.
This left him with a faint feeling.
'Magic that can transform into an imaginary system magic is probably only the magic learned in this world.'
Magic he learned in other worlds shouldn't be affected by his imaginary system compatibility. However, even if he were to learn the magic in this world, it remained uncertain whether another imaginary system magic, like his decomposition magic, could emerge.
'Well, if it's not there, then it's not there.'
After some consideration, Riezel decided to let things take their course.
At least, after his decomposition magic became imaginary control system magic, not only substances but even the magic itself could be decomposed. This change was undoubtedly very pleasing.
Such a powerful magic could already be used as a trump card.
Most importantly, decomposition magic was chantless magic, able to be activated and released at any time in an instant, which further increased its practicality and convenience.
'Since I have 'Mage' and have accumulated a lot of 'MAG', as long as I can skillfully use this magic, there's no reason I can't enhance its power and range of effects in the future, right?'
As long as he kept growing, kept leveling up, his decomposition magic would eventually possess destructive power on a tactical-class and strategic-class scale.
As he thought like that, Riezel's regard for decomposition magic was already above that of 'Ariel', another overpowered magic.
Ariel was an enhancement type.
Decomposition magic, however, was an offensive type.
Riezel's mind was already teeming with various ways to use decomposition magic, making him eager to try.
Fortunately, he had enough patience and didn't lose his sense of reality. He temporarily set aside issues concerning decomposition magic and focused on learning various useful magic as well as magic theory and knowledge from Yuri.
—Knowledge is a magician's greatest wealth. Only with sufficient magic theory and knowledge can a magician go further.
Adhering to that principle, Yuri taught Riezel theories and knowledge of magic quite diligently.
As she claimed before, she was indeed a quite strict teacher, and if it weren't for Riezel's good memory, he might have had trouble keeping up.
This was how he spent three days traveling on the ship.
===
Three days later, the ship finally entered Frenzel territory, entering the northern region.
This place was forever winter, with very low temperatures.
Throughout the year, one couldn't get by with anything less than winter clothing, as even in autumn, it was too cold without them.
It was said that the first half of the year was relatively warm, while the second half was snowy throughout. Hence, half of the year in Frenzel territory was always a white snowfield.
Yuri's timing for this return was quite apt, as it was currently the first half of the year, so there was no snowfall.
When it snows, the river freezes, and as a result, ships become unable to navigate. When that happened, everyone had to switch to horse-drawn carriages, spending quite some time before they could return to Frenzel territory.
Finally, the ship arrived at the city where the Frenzel family's main residence was located—Undine.
It was a city of moderate size but held significant geographic importance. If Yeluvia was considered the capital of all Jinas, then Undine was the capital of the Frenzel territory.
While not as bustling as Yeluvia, it exuded an exotic charm, serving as a major trading hub where merchants and caravans conducted business or passed through, making it quite lively.
The Frenzel family's main residence lay in the heart of Undine.
"We've arrived, My Lady."
Ain and Ian, who drove the carriage, were the first to disembark and helped Yuri out of the carriage.
Marilyn followed closely behind Yuri, step by step.
Riezel was the last to disembark, catching sight of a huge manor resembling a white castle.
"Is this the main residence?" Riezel murmured.
"Let's go." Yuri beckoned everyone to enter the manor together.
However, this young lady didn't seem at all like a child returning home after a long absence. Her expression was cold, her gaze sharp, devoid of any joy of returning home. Her demeanor was more akin to entering a battlefield than returning home.
Nevertheless, Yuri's return drew quite a crowd.
"Welcome back, My Lady."
A steward bowed at the entrance.
""Welcome back, My Lady!""
Many voices, neat and tidy, rang out in tandem.
At the entrance, on either side of the steward, many people stood, forming two lines along a long red carpet, bowing respectfully in the direction of the carpet.
Among these people were knights and maids, roughly numbering around a hundred or so.
The grandeur they displayed was quite luxurious.
Unfortunately, Yuri didn't even glance at them, proceeding forward along the red carpet. Only upon reaching the entrance did she finally stop and speak.
"Where's my father?" Yuri's voice was exceptionally cold.
"Ma-Master just happens to be out of the house..." The steward hurriedly approached, his voice filled with nervousness.
"Not here?" Yuri quipped. "Did he run away?"
"That..."
Cold sweat dripped from the steward's forehead.
Yuri unleashed an unpleasant aura as she glanced at the steward.
"Tell him I need to speak with him and I need him to come back immediately."
"Uhh..." The steward looked visibly troubled.
Upon seeing his reaction, Yuri had only one thing to say.
"If he doesn't want to come back and talk things out with me, that's fine." Yuri suddenly smiled. "But, don't blame me for doing something irrational later, just like in the royal capital."
Her words and smile, devoid of any hint of warmth, made the steward's legs go weak.
What exactly happened in the royal capital had already spread, and of course, the steward was aware of it. Now, seeing his lady return unharmed, he felt both relieved and apprehensive. There was just too much information to process, leaving him no choice but to speculate.
"I-I will inform the Master to come back as soon as possible!" The steward could only speak up with a stiff tone.
Upon hearing that, Yuri continued walking.
"I've invited my schoolmate to come over, so prepare the best room for him."
Leaving behind those words, she quickly entered the manor.
Marilyn, Ain, and Ian remained silent throughout, following her footsteps.
Watching all this, Riezel's heart secretly trembled.
'What a queen...'
Yuri was truly a scary woman when angry, no doubt.
