Girl in the Box: Please tell me why I was reincarnated as a mimic monster!

"Go! Go! Go."

"Do you really treat me like a dog?"

"What do you say?"

"Wang Wang Wang!"

"Tsk?! Don't come near me!"

The two bickered for a while longer, but Sevi was still completely overwhelmed. There was nothing he could do; after all, he was a gentleman... no, he should be called an adventurer.

After a while of commotion, nothing came of it. Having nowhere to vent her anger, Aye simply beat up Sevi. Just then, she seemed to hear a noise.

"Quiet down." Aye covered her lips with her hand.

"Wow, you're hitting me like this and I'm not even allowed to scream?!" Saiwei cried out.

“Shut up,” Ayer punched him, “Something’s come in.”

“…Yes, there is.” Savi also became serious. “It’s over there in the book…”

"Books..."

Aye stood up quietly and slowly approached the pile of books, but she didn't see anything suspicious. She looked back at Savi, who also shook his head, indicating that he hadn't seen anything suspicious either.

Ayer walked into the pile of books and found one that was rapidly turning its pages, with other books around it also turning. This was probably the suspicious thing they were looking for.

Ah... I long to read, I long to read to my heart's content in the library... I'll die without books to read... I'll die without new knowledge...

A black book wanders through the maze. Most people would probably think it's some kind of monster, but it's not a monster at all. It's a book that has been placed somewhere for a long time and has gained spirituality due to the influence of its origins. It's a book that pursues the unknown and knowledge.

Actually, this book is very famous in the world because it knows everything. As long as you can exchange it for knowledge or books that it doesn't know, after verification, it will answer you with everything it knows.

Many people have successfully obtained all sorts of truths, even ways to get rich, from it, making it extremely popular. However, it can't always stay in one place for a very long time (except for libraries). It travels the world in search of unknown knowledge, so being able to meet it is considered very lucky.

Of course, some people want to catch it, but that's impossible. It's said that it can use any magic to retaliate against anyone who is hostile to it.

It is called the Black Feather Book because it has a black feather bookmark.

Today, it was also wandering around, searching for what it desired. Then, it caught the scent of knowledge.

What a wonderful smell of books...! There are books around here!

Excitedly, it followed the scent of books and found their location, which were all concentrated somewhere in this maze.

Okay...! Let's rush in and grab the book in one go!

Chapter 34 The Book of Universal Magic

Black Feather's magic book immediately opened its pages, releasing the magic it had memorized. A silver-white magic circle was imprinted on the stone wall—a spatial magic that few in the world could master. Without hesitation, it immediately floated inside.

On the other side of the magic circle lay her destination, a labyrinthine cave. Its intuition for knowledge was exceptionally accurate; it was the only thing it was truly confident of, firmly believing that books were piled up somewhere there.

It entered the dimly lit cave, illuminated by soul grass, its light weak but enough to make out the cave's layout. It looked like someone had lived there, but that wasn't its concern; it was more interested in where the book was.

Where is the book...?

It was already thirsting for new knowledge, wandering back and forth in the cave looking for books. Then it saw the books placed in front of a large black stone slab, and pounced on them like a pirate who had found treasure.

Using its unique skills, it quickly browsed through these books, creating a spectacular sight of several books flipping through at high speed simultaneously, a sight that evoked a sense of awe no matter how many times it was viewed. After rapidly scanning the contents, it discovered that these were books it had already read, and that the content was marred by various annotations, which it found extremely offensive and a desecration of knowledge.

What... this outdated knowledge... wait...? What is this?

It suddenly noticed that the contents of these books were somewhat different, especially in the annotations. It flipped through the books again and discovered the problem: the annotations in these books were all in characters it didn't recognize.

This! This is! This is an unknown raw stone!

The words appeared very frequently, as if recording something, calculating something, or pursuing something. This alone was an unprecedented experience for it; it was something it didn't know, and it was very glad that it had found this place.

marvelous……

It then perused some other books, almost all of which contained a vast amount of notes, and the handwriting was similar, mostly written by the same person. It now longed to leave immediately to find the person who wrote these words and exchange knowledge, but that would be a desecration of knowledge; it would read all the books here before leaving.

These books are—! My goodness—!

It stumbled upon something even more amazing. Books written entirely in a script it didn't recognize... no, the script was so neat and beautiful, it didn't look like handwriting at all, and it was accompanied by almost lifelike illustrations. This was a treasure trove, a true treasure trove!

I made a profit!

It immediately transformed into human form, sat among the pile of books, and began doing what it loved most: reading.

"Hey...you saw it, didn't you..." Aye couldn't believe her eyes.

"Don't tell me you didn't see that..." Even Savi himself couldn't believe it.

What they were seeing now was a book that was flipping through other books, and simultaneously. They had heard of this book in their field of knowledge, but they had always considered its existence a legend.

"Black feather bookmark..." Aye couldn't help but swallow hard, "Black book cover..."

"Black Feather's magic book..." Savi stared intently at the book.

Black feather bookmark, black cover—they couldn't be mistaken; this was the legendary Black Feather Magic Book, a book said to be omniscient and omnipotent. Just present it with books or knowledge that please it, and after verification, it will tell you what you seek.

While it couldn't directly grant any wishes, the intelligence was absolutely accurate. They never dreamed they'd find it in such a place; it wasn't some mythical, fabricated magic book.

“This thing is real…” Savi felt like he was about to burst out laughing. “There really is such a thing.”

“‘The Book of All Principles’… This is the first time I’ve ever seen one.” Aye muttered to herself, “Why is it here?… Oh, I see. That makes sense.”

"The 'Grimoire of All Principles'?" Savi looked puzzled.

“That’s its real name. You common folk only know the popular, rumored names.” Aye rolled her eyes at him.

Aye knew something about the "Grimoire of All Principles" rather than the legends circulating among the people, because someone in his tribe had successfully traded the "Grimoire of All Principles," and the process of these transactions had been recorded, which Aye was also aware of.

The 'Grimoire of All Principles' doesn't wander aimlessly; it's constantly searching for places with new knowledge and books, as well as for the unknown future. Therefore, it most frequently appears in libraries and ruins around the world.

Its presence here indicates that the books here are captivating, and their content is something it is completely unfamiliar with. Now, Aye has an idea.

Buzz~~

The magic book suddenly emitted a black light, enveloping itself in it. When the light faded, a naked girl with silver hair was sitting there, holding the book and reading intently, her smile radiating immense joy.

"—?!"

The two were shocked by this sudden change. Aye immediately poked Savi's eyes, then slapped Savi, and casually picked up a piece of animal hide and put it on his head to restrain him.

"—!?—!!—?!"

Completely ignoring Savi's struggles and screams on the ground, she immediately grabbed the spare clothes and put them on him. Unexpectedly, the extra clothes she had made earlier came in handy.

"~~?! What's wrong?!"

The naked girl was suddenly dressed and became very unhappy. If she remained naked like this, something bad would really happen. Aye couldn't help but wonder if this girl was truly the 'Grimoire of All Principles'?

"Don't you even know basic human decency? Put your clothes on properly," Aye said, somewhat exasperated.

"I am a book spirit, not a human," the girl retorted confidently to Aye. "Don't categorize me as that kind of creature. I am the all-knowing grimoire of all principles! Black Feather!"

"Okay, okay... Come here, let me help you get dressed. There's a stupid man over there." Aye pointed to Savi lying on the side.

The girl glanced at it and surprisingly became unusually compliant: "...I understand."

"—?—!??!"

Although she couldn't understand what Sevi was saying, Aye guessed he was arguing, but it was pointless. Also, she learned something else.

Even the book spirit girl known as the Book of All Principles has a sense of shame.

Chapter 35 Contract established

“…” “…”

Ever since the grimoire girl was dressed, she had been completely absorbed in reading. The two people beside her were clearly not as captivating as the books.

So, a long silence fell over the place, and they haven't spoken to each other yet, creating a very awkward atmosphere.

"Hey... Aye, can this book turn into a person?" Savi asked in a low voice.

"I don't know either..." Aye was completely baffled.

She had never heard of this magic book being able to turn into a human.

Her previous actions were entirely instinctive; she subconsciously restrained Sevier first, and then immediately dressed the girl.

Now that things had turned out this way, she didn't know what to do. Besides, the other person was completely absorbed in their book, ignoring them entirely. Savi probably had a lot of questions to ask, but she certainly couldn't expect him to pay any price, so this part was up to Aye herself.

Depending on the other party's response, the investigation may proceed directly to the core issues.

“Hey… Wanli Demon…” Aye spoke to the girl.

"Just call me Kuroba, or you can call me Yu," Kuroba corrected her without looking up.

"Is that so? Well, my apologies." Aye coughed twice. "Ahem, Miss Kuroba, I remember you traveled the world in search of new knowledge and books, didn't you?"

“Yes, that’s right.” Kuroba still didn’t look at her. “Is there a problem?”

"To be honest," Aye said with a wry smile, "all the books here are mine. What you're doing is really bothering me. You're not some unreasonable book spirit, are you?"

Savi, who had been watching Aye's actions with complete bewilderment, now understood Aye's meaning. By first informing Kuroba that the books here belonged to Aye, Aye was subtly implying that Kuroba couldn't just sit there reading without paying the price. Therefore, Aye now held the reins.

That old woman is quite something...

Savi watched Aye's retreating figure. He had his own plans, but she had beaten him to it. He now intended to play dumb and sit to the side, waiting for Aye's information. He also had questions he wanted to ask, and he was prepared for the consequences. He had originally brought it along just for a bit of good luck, but he hadn't expected the luck to go too far.

Now, all LDK needs to do is wait and see.

"...Are all these books yours?" Kuroba reluctantly raised his head. "Well, I guess these books probably have owners. In order not to let them down, I naturally have to pay my price."

"Oh, I'm glad you understand." Aye smiled and got straight to the point, "You should be able to understand these books, right?"

The common trait of book spirits is that they can fully understand all languages, but it takes time to fully master them. Kuroba, as a book spirit, is no exception, so Aye wants to use her power to understand all these books as soon as possible.

“Of course I understand,” Kuroba said proudly. “No book can stump our Book Spirits.”

"Then I'll leave it to you." Aye secretly handed the most important notebook to Kuroba. "Please be sure to translate the contents of this book for me."

“…I have indeed received the price,” Kuroba said after a moment of silence. “Then let’s make the contract.”

Black Feather's fingers gracefully traced lines in the void, causing the magic scattered in the air to gather and float in the void, forming words that were then constantly shifted and recombined, creating the unique contract document of the Book Spirit Clan.

Aye signed the contract, and the contract, made of magic, transformed into particles of light and merged into both of their bodies. The contract stipulated that Kuroba would exchange the book in Aye's possession for translation.

What she didn't know was that Aye was lying; the books didn't belong to her. She had simply set a trap for Kuroba's preconceived notions.

However, Kuroba obviously didn't care about those things. She was more concerned with the knowledge and content in the book, which allowed Aye to take advantage of the situation.

“Then please wait a moment,” Kuroba said, picking up the book. “Analyzing the content takes time, but I’ll translate it for you as soon as possible. Do you have a pen and paper?”

"...Do you have it, Saiwei?" Aye didn't have that kind of thing.

“Even if you ask me, I don’t have such a thing…” Savi scratched his head in frustration. “Why would I bring such a thing with me? Let me look around and see if I can find it here.”

After saying this, Savi stood up and went to look for something similar to pen and paper in other parts of the cave. This cave had almost everything, and even if it didn't have something, there would be similar substitutes. Finding such a thing shouldn't be a problem.

“Although the blackboard in the back can also be used, the contents on it are very precious.” Kuroba looked at the blackboard behind him. “Mountain tribes also record things in this way. They smoke the stone walls with fire until they turn black, and use softer stones to make pens to write on them.”

"I thought it was an original creation..." Aye said with a wry smile.

"I wouldn't call it original, but it's definitely more advanced." Kuroba touched the blackboard with his hand. "The texture is smoother than the ones made by the mountain tribes, and it seems to be able to move... However, the content on it is indeed original. I think I'll have to spend a long time here studying it."

So this is indeed the most important thing...

Although I already thought it was something extraordinary when I first saw it, now that even the Book of Myriad Principles confirms it, it's certain that the caster once lived here. All that's left is to catch him by the tail.

“Found it.” Savi returned with the parchment, a bottle of ink, and a pen. “Here you go.”

"Thank you." Kuroba took the pen and paper, a look of surprise on his face. "This is...!"

She noticed the unusual-looking pen and the ink bottle. She put down what she was holding and picked up the pen to examine it. The pen was very heavy, with a streamlined shape and a metallic sheen, suggesting it was made of some kind of metal. The craftsmanship was incredibly exquisite.

There were also ink bottles, bottles she had never seen before. Although she had seen crystal-clear bottles in this world, she had never seen transparent ones. Although the texture was rough, it was something that could not be made with the current technology of this world.

"Hey... Savi, is this really a pen?" Aye asked quietly. "I don't think it looks quite right to me."

Aye looked at the unusual pen; she had never seen anything like it before, and it just didn't seem right.

“That is indeed a pen,” Sevi said calmly. “There’s something inside that can extract and store the ink, so it can be used for a while even without ink. The Duchy has something similar, but that’s a child’s toy.”

“I see…” Aye nodded. “There’s such a thing.”

After fiddling with the pen for a while, Kuroba figured out how to use it and quickly got to work translating. The translation wasn't fast; it was estimated to take at least a day. During that day, Sevie and Aye probably wouldn't have much to do.

“Hey, Aye,” Sevi asked, “what’s written in that book? I’ve never seen it before. Did you hide it?”

“It’s nothing,” Aye said mysteriously. “It might just be someone’s diary.”
