In the Royal Library, Grimm is transcribing the magic book of the four-ring spell "Anti-Gravity".

"Anti-gravity" is one of the pre-spells of "Netherel Core", and its status is equivalent to the relationship between "algebra" and "advanced mathematics", but even this "pre-spell" still has a lot that Green does not understand......

One of the disgusting things about magic that Green found was that you had to understand how it worked. If you don't understand the principles of magic, you won't be able to cast spells, even if you have enough magic, even if you remember spells and spell models.

At this time, Green had completely given up studying, and directly turned into a book copying maniac, planning to copy the necessary materials first, and then give them to others to learn. Or wait until you've finished all the theoretical knowledge before you can go back and learn these spells.

Just as Green was using the system interface to frantically copy books, a half-elf woman came to the library.

It was a middle-aged woman, with pointed ears faintly visible under her silver hair, but not as long as the elves' ears. Obviously, this is a half-elf. The half-elf has a slight wrinkle on her face and a somewhat fat figure, looking like a middle-aged human aunt.

The middle-aged aunt seemed to be very familiar with the library, and after walking into the library, she came directly to the pile of books where the elf was sleeping, and looked down at the elf: "Books." ”

Hearing the words of the middle-aged aunt, the elf administrator raised his head from the pile of books: "It turned out to be President Bass, good morning." ”

"It's already afternoon." The middle-aged aunt glanced at Green, who was sitting not far away, "Who is that person?" I don't think I've seen it before. ”

"A freak, where the Queen allowed him to borrow books from the library."

"Freaks?" The middle-aged aunt looked at the elf in front of her who was the master of the library with strange eyes.

The elf didn't seem to notice the strangeness in the middle-aged aunt's eyes: "Are you looking for any books?" ”

“…… Open the magic library, I'm going to look it up. The middle-aged aunt spoke.

"Okay." The elf climbed up from the stack of books, "What do you want?" ”

"I'm going to borrow that Nesserel Core Research Notes." The middle-aged aunt spoke.

"Oh?" The elf's expression moved slightly, "Your research is at a bottleneck?" ”

"Yes, it didn't go well...... Wait, how do you know what research I'm doing? The middle-aged aunt looked suspicious.

"Oh~ how many years do you think I've been a librarian here?" The elf snorted twice, "When Master Carolan was researching the magic core back then, I also made a lot of suggestions. ”

The middle-aged aunt's expression moved slightly: "...... Do you know how to make fictional gravity replace real gravity? ”

"I haven't studied it. I'm just an academic, not a researcher. ”

The two chatted as they walked into the depths of the library.

At the same time, Green raised his head and looked in the direction the two had left, his eyes flickering: "Let fictional gravity replace real gravity?" ”

Green's eyes narrowed slightly, and he felt as if he had heard something he shouldn't have heard......

Green put down the book in his hand and began to think carefully.

The middle-aged aunt did not read the book in the library, but directly borrowed the book.

After the middle-aged aunt left, Green approached the elf who was sorting out the formalities: "Who was that person just now?" ”

"President of the Magical Society." The elf put the papers away and locked the drawers.

"What is he doing here?"

"What else can I borrow?"

Green squinted, "Books, did Angsari really rely on the Netherriel core to control the gravity ring to move?" ”

Hearing Green's inquiry, the elf raised his eyebrows: "Why do you think so?" ”

"Because it's weird, isn't it? The core of Netherel is an item that combines gravity control and infinite energy to turn ordinary mountain peaks into floating islands, but the main body of Angusari is the floating stone! It's weird. Green's eyes lit up, "Don't you think the Eleventh Ring Spell is a little too difficult?" The Floating Stone can already float in the air, so it doesn't need the Angsari core at all, right? Just figure out how to solve the mobile problem...... For example, all you need to do is change gravity! ”

The elf looked at Green with a strange expression: "That's right...... You don't really plan to build a floating city, do you? ”

"Don't you want a floating city as a territory?" Green stared at the elf, "A mage tower of his own, on the Floating City." Have your own library, comfortable room, go wherever you want. ”

Elf: "......"

Greene: "Floating City is the romance of mages!" ”

"Hmm......" the elf closed his eyes and imagined, "Okay." Sounds tempting indeed. ”

"Book, tell me, what method did Angsari use?" Green stared at the elf.

“…… I don't know, it's a royal secret. The elf didn't want to say more.

Green raised an eyebrow. Secret? I like confidentiality the most!

The elf didn't say anything, but Green wasn't disappointed in the slightest, but was very excited. Because it means that you have probably touched the truth!

Green is in the palace at this time, and if he wants to steal the kingdom's secrets, this is his chance.

Green slowly wandered around the library, observing the books on the shelves. The Royal Library is worthy of being the highest level library in the kingdom, and Green found a map of the royal palace on one of the shelves!

"Confidential documents...... The possibility of placing it in the den is the highest! Green's fingers moved slightly, and he connected with Thousand Shadows through his spirit, "Thousand Shadows, how is your stealth ability?" ”

The shadow under Green's feet moved slightly: "...... I have no memory of this. But...... Master, I have to protect you. ”

"It's not that you don't know my current strength, even without your protection, no one can kill me." Green vetoed Chikage's kindness, "Do you have a way to sneak into this study without being discovered?" ”

“…… I can try. ”

"Hmm......" Green hesitated.

[Stealth] and [Stealth] are similar, but they are two different things. Invisibility is able to make people unable to see themselves, and when encountering a person with high perception, you can instinctively perceive the abnormality even if the other person can't see you, while stealth is different - stealth is not discovered and makes people ignore themselves. Chikage can walk in shadows, this ability is very similar to stealth, and it is very useful when dealing with low-level enemies, but once it encounters a strong person with high perception, it is useless at all.

After hesitating for a moment, Green decided that it would be better to investigate again and be on the safe side.

While Green was looking at the materials, Queen Rhea suddenly appeared in the library.

"Yo~ Her Majesty." Lying in the stack of books, the elf beckoned to the queen without any manner, "Have you not always hated reading?" How do you have time to come here? ”

"I heard that there was a new 'resident' in the library, so I stopped over and had a look." The queen looked at the elf condescendingly, "How is your new neighbor?" ”

“…… He's the craziest human I've ever seen. The elf glanced at Green, who was standing not far away, "He's been staying in the library and reading like crazy for the past few days. ”

Queen Rhea glanced at Green, who was putting a book back on the shelf: "What books did he read?" ”

"Nesseriel Core Research Notes, Spell Principles and Models: Fictional Gravity, Spell Principles and Models: Antigravity, Spell Principles and Models: Otherworldly Protective Bubbles, and many other books on Floating Cities and gravity." The elf paused, "It seems that he is really interested in the Floating City. ”

Hearing the elf's words, Queen Rhea was stunned for a while: "He has already read so many books?" ”

"Yes, he's the craziest reader I've ever met, and he's a very fast reader."

Queen Rhea's eyes flickered.

The voices of the two of them were particularly noticeable in the quiet library. Green looked at Queen Rhea, dressed in military uniform, and began to think about what he should do......

If you want to sneak in, Queen Rhea is definitely the one you must avoid! The Golden Archer's perception is very powerful, and even the legendary thief may not be able to evade her perception, and the extraordinary abilities of invisibility and shadow walking do not mean much in front of the Golden Archer.

Just as Grimm was thinking, Queen Rhea walked over to Grimm: "Are you used to staying here?" ”

"It's ok. I am very satisfied with the collection of books here. At this point, Green already had an idea in his head.

"It's been a long time since you've been back to school, and your headmaster has already started protesting to me."

"Oh~ Your Majesty, the knowledge in the school is not as good as the library you have here."

Queen Rhea: "Are you going to stay here forever?" Not planning to go back to school? ”

"I'm not going to leave yet." Green has the attitude that I want to call this place home.

"Don't you need to go back and take a shower and change your clothes?"

"No, I don't. I'm very clean. [Cleansing] and [Healing] are two good spells. ”

Queen Rhea looked at Grimm and then at the elf lying in the stack of books, and couldn't help but sigh in her heart, "The world is so big that there are no wonders", and there are more strange things in this world than she imagined.
