The voice reached Fang Li's ears before he had a chance to see the panoramic view inside the door.
It felt as if someone had known all along that someone would come here at this time, allowing the clear, cold voice to resonate distinctly.
Similarly, Fang Li showed no hint of surprise or accident, but merely smiled lightly and cast his gaze into the room.
The next moment, a library came into Fang Li's view.
It was a genuine library.
Rows of shelves lined the room, filled with thick books.
The library's expanse was even wider than the guest room Fang Li had stayed in before, easily twice the size.
As for the books themselves, each emitted an unusual scent, giving the library an atmosphere not of the common scent of books but rather one permeated with mystery.
In such a library, right in front of the door, stood a pretty and cute girl.
The girl appeared younger than any acquaintance Fang Li had made so far, and in terms of appearance alone, she was no different from Fan Xinglou.
However, unlike Fan Xinglou's elegant attire, the cute girl wore a luxurious dress with many folds, giving off a princess-like vibe.
She had her hair tied up in spiral-shaped twin ponytails, the color of which was a golden hue resembling ripe wheat.
With a large book in her arms, the girl sat on a stool, her head lowered as she flipped through the pages.
Undoubtedly, when Fang Li opened the door, she didn't even bother to raise her head before speaking.
Until now, she might not even know what Fang Li looked like.
As Fang Li's gaze entered the library, the girl finally raised her head and met Fang Li's eyes.
The girl's youthful face was adorned with a pair of eyes as blue as the sea.
"Is it you?" The girl said with an unfriendly attitude, staring directly at Fang Li.
"The rude person who intruded into Betty's forbidden book library in the dead of night."
Hearing these unfriendly words, Fang Li only showed an expression of disapproval, as if dealing with a sulking child, and spoke without hesitation.
"If you don't want others to intrude into your room, then lock the door. Even children understand that common sense."
At this, the girl calling herself Betty's eyebrows twitched slightly, and her gaze at Fang Li remained unchanged but turned somewhat displeased.
Clearly, Fang Li did not give a good first impression to the girl.
Or rather, since coming to this mansion, Fang Li had not given a good impression to anyone here.
Whether it was Rem, Ram, or the girl calling herself Betty in front of him, presumably, Fang Li's impression on them had been extremely negative, right?
"And then?" The girl said in an even more unfriendly tone, looking at Fang Li. "What do you plan to do in Betty's forbidden book library?"
"What else can I do in a library?" Fang Li shrugged nonchalantly, smiling unabashedly. "Of course, I came to read books, didn't I?"
With that sentence, the air around them seemed to drop to freezing point.
*Pā!*
With a crisp sound, the girl forcefully closed the book in her hand.
"Not only are you rude, but also very bold," She said, her tone becoming lower, her azure eyes staring at Fang Li, now filled with hostility.
"If you knew about the existence of this forbidden book library, then you should understand that such words are simply provoking Betty, aren't they?"
The girl's reaction was understandable.
After all, the books stored in this forbidden book library were not ordinary books but Magic books.
The Mathers Clan was known as a Warlock Clan, generation after generation of renowned Magic users and even Spirit Warlocks, with a lineage spanning hundreds of years, making it deeply rooted in history.
The accumulated knowledge of Magic by the talented individuals of the Mathers Clan throughout the generations was truly astonishing.
Now, all that knowledge was contained within this library.
The books stored in this forbidden book library were Magic books that recorded the Magic knowledge passed down through generations of the Mathers Clan.
Their preciousness needed no explanation.
If Roswaal permitted it, I believe Magic users and Spirit Warlocks from all over the world would be willing to bankrupt themselves for a chance to acquire a book here.
In such an important place, it was naturally impossible for it to be unguarded.
The girl who called herself Betty was a Spirit tasked with guarding this forbidden book library, bound by a contract for four hundred years.
Similar to the Spirit known as Pack.
In this situation, for Fang Li to suddenly intrude and even openly declare his intention to read the forbidden books here, wasn't that provocation?
"Or are you underestimating Betty?" the girl extended a delicate palm toward Fang Li, her eyes glittering as if stars were shining within them.
"So, Betty hates humans."
With that said, the atmosphere around the girl distorted.
*Wū——!*
Under the trembling of the space, a dense wave of fluctuation surged throughout the forbidden book library, converging toward Betty's outstretched hand.
Fang Li could clearly feel a force at work in the atmosphere.
"So this is Magic Power?"
Just as in the world of Genestellar, where Strega (Witches), Magecraft users, and Daoshi alike utilized Abilities and Seisenjutsu that required the expenditure of Prana, in this world, there existed a power similar to Prana, spreading throughout all things like Mana.
And when casting spells like Magic, what was consumed was Magic Power.
Magic Power was also known as Mana.
Now, the Mana in the atmosphere reacting to the actions of the girl calling herself Betty only confirmed one thing.
That she was preparing to use Magic.
"Interesting..."
A smirk formed on Fang Li's lips as he suddenly gripped a sharp dagger in his hand.
The ice-blue Mystic Eyes manifested in Fang Li's eyes.
*BOOM——!*
The next moment, centered around the girl's hand reaching toward Fang Li, an invisible ripple surged out like a shockwave, roaring through the air, rubbing against the atmosphere on one side while rushing toward Fang Li on the other.
The speed was comparable to that of sound.
However, Fang Li had long been prepared.
So...
"I see..."
The Death Line of the shockwave rushed toward him like a raging storm.
*Pū chī——!*
As if piercing through a physical body, the sharp dagger flashed suddenly, slicing the incoming invisible wave in half.
"What?!"
The girl was instantly shocked.
"You cut through Magic with a weapon?!"
To this question, there was only one response.
"It's not cutting through, it's killing."
With those words, the dagger suddenly cut through the air, thrown by Fang Li's hand with a sharp sound, piercing toward the girl with the intention of breaking space.
