Half an hour later, at the First Library of Nahuat.

This is an extremely magnificent building, and it can even be said to be the most magnificent building Rosen has seen since he came to the Nawat plane.

Naya led the way. "This library contains almost all of Nahuat's knowledge. It has five floors above ground and five floors underground. The total collection of books exceeds one million. It is the largest library in our country."

"Master Rosen, in view of your outstanding contribution to the national security of Nahuat, you can copy four books in the Temple of Wisdom and have 2 hours of free choice time."

Rosen's heart was slightly moved when he heard this: "Two hours of free choice means I can browse through it?"

Naya nodded: "Yes, you can take a quick look to determine the general content of the book to avoid making the wrong choice."

"But you must pay attention to two points. First, you must be careful when reading to avoid damaging the book. Second, you must not use any spells to assist in recording."

Rosen was secretly delighted: "I understand. Thank you Master Naya for your explanation."

Naya did not doubt him and continued to explain: "I personally recommend that you must copy the following three books."

"One is called 'Encyclopedia of Void Life', one is called 'The Power of Faith', and the last one is called 'Legend'."

"These three books correspond to most of the knowledge on fighting demons, and provide in-depth discussions on the power of faith and the legendary realm, which are exactly what you need."

"Besides that, you can make a copy at will."

After that, he looked at Zigrelana again and said, "Ms. Zigrelana, you have obtained the right to copy a collection of books. I personally do not make any suggestions."

Ziglarana asked, "Can I copy whatever I want?"

"That's right. You can copy any book from the Temple of Wisdom that you like."

"Considering that you are not familiar with the basic contents of the books in the temple, I will act as a guide and briefly introduce the contents of the book to you."

"Understood."

As they were talking, the three of them entered the library.

The two followed Naya through a wide and tall corridor, and then walked down a spiral staircase leading to the underground for about five minutes. Finally, they passed through several layers of thick defensive barriers and arrived at a somewhat narrow library.

There are not many books in the library, less than 1,000 in total, but the titles of each book are very amazing.

Rosen glanced casually and saw "The Battle of Destruction - Encounter Record of Level 19 Demon Gao Miller", "Exploration of the Essence of Light - Detailed Explanation of the Light of Destruction", "Super-aggregation Phenomenon of Elements", "Exploration of the Essence of Elements", etc.

The names of each book are very big, and they are well deserved. They are amazing technical results that truly combine theory with practice.

Obviously, Nahuat's 800-year history of fighting against demons is also 800 years of searching for stronger demon-slaying power. They have really tried every possible way.

Looking at these extremely precious books, Rosen even had an urge to join Navarat.

With his wisdom and various prophetic visions from Earth, if he could occupy a dominant position in Nahuat, he would definitely be able to vigorously promote Nahuat's research on magic. Maybe in 100 years, he could evolve into a magical interstellar civilization and turn gods and demons into protected animals.

But this impulse lasted only a moment and then disappeared.

Because to Nawat, he is an outsider after all.

No matter how hard outsiders try, it is impossible for them to truly enter the top level of a huge country, let alone dominate the country.

This is universal human nature.

Just think about it and you will understand.

A big and colorful family, everyone is a blood-related relative.

Now a stranger who has no blood relationship with you comes and wants to control your people, use your money, and be the master of your family. If you are still willing to do this, you are definitely a fool.

In comparison, returning to one's own plane, managing a group of one's own people, and managing it bit by bit is the reliable way to gain great power.

While thinking, Rosen found the three books recommended by Master Naya.

He did not rush to confirm, but flipped through the pages one by one. After quickly flipping through them, he finally nodded to confirm.

It took an average of ten minutes to read each book, which was not fast, but definitely not slow, and no magic was used during the process.

Although Naya felt it was a little bit strange, she naturally attributed it to the mage's strict character and did not think much about it.

After Rosen confirmed the three books, Naya handed them over to the library assistant for transcription.

Finally, you can make a copy.

Rosen walked among the precious books in his collection. When he saw a book title that interested him, he would take it and read it carefully, page by page.

I read three books in one go, all of which were very thick.

The value was also incredibly high, so I spent twenty minutes reading each book. By the time I finished, an hour and a half had passed.

He had half an hour left to choose.

Then, Rosen saw the book "The Essence of Light - Detailed Explanation of the Light of Destruction".

He had dealt with the Artifact of Light of Destruction once before and was deeply impressed by it, so he took a closer look at it.

When he saw this, he was shocked: "Isn't this the knowledge of the Glorious Empire?"

Rosen had a very deep understanding of the power of light. He could tell at a glance that a large part of the knowledge in this book definitely came from the Glorious Empire.

Naya happened to be standing next to him. After a little consideration, he asked directly: "Ms. Naya, is Nawat also connected to the Glorious Empire?"

Naya was startled, then nodded: "Yes, the Glorious Empire is a great country. Our two countries have a lot of cooperation in various magic techniques."

“Oh~”

Rosen nodded and stuffed the book back.

Although he remained calm on the surface, his heart was filled with turmoil: "Fortunately, I left a tip in the alchemy manual."

He continued walking forward, and then he saw a very thin book, probably less than fifty pages, with a completely black cover and a small title written on it.

"'Exploration of Plane Crossing'."

Rosen's heart moved and he stopped in front of the book.

Naya had been following him, and when she saw him stop, she followed his gaze and gave her advice.

“The content of this book is very groundbreaking and inspiring, but because the research is extremely difficult, it is not in-depth.”

Rosen smiled and said, "I like this kind of groundbreaking ideas the most. You have to take a good look at it."

Naya nodded: "Look, this book is not very important, and the content is not much. You can just stand here and read it."

After saying that, she turned around and went to look for Zigrailana.

Rosen first flipped through the book, entered it into the Lai Fu database, and then began to read the first page carefully.

Because of limited time, he only planned to read the first few pages.

The first chapter is titled "Plane and Stars May Be the Same Thing."

The title alone attracted Rosen's attention, and he immediately read the content.

"Plane-traveling mages have existed since ancient times, and high-level mages have always known about the existence of multiple planes, but no one can clearly explain what a plane is."

"I have spent hundreds of years studying and observing the sky in all planes, comparing them as precisely as possible."

'I discovered that all currently known planes most likely share the same sun!'

'The distance between the planes is not as far as the plane-walkers imagine. Of course, it is certainly not close. But I guess it should be the interstellar distance in the unit of 100 million kilometers.'

Looking at these introductions, Rosen's heart was shocked, and he continued to read.

The following is a detailed demonstration process, with star maps and various calculations.

Because the data is not very accurate, the final conclusion is not particularly convincing, but it is indeed very groundbreaking.

At the end, the author also fantasized and proposed the idea of ​​not using magic rings for phase transfer, but directly creating a powerful magic weapon, flying out of the planet, crossing the star realm to reach another dimension.

Rosen was simply fascinated.

He felt that the conclusions of this book were most likely correct and very easy to verify. All he had to do was check the solar spectra of various dimensions.

The spectrum of each star is unique, and as long as the spectra match, that plane naturally shares a star system.

"If it is true, there are so many planets with life in one star system, and they are connected by magic rings. It is really lively!"

At the same time, there is also a sense of urgency, because in this situation, as long as one world develops the power of interstellar travel, it will be a crushing blow to other worlds.

It can be said that when an interstellar spaceship from one world appears in the sky of another world, it means that all the mortals in this world will become slaves.

At this time, Naya came back and asked, "How is it, have you finished reading it?"

Rosen nodded. "It's a very interesting book, but the idea is indeed quite unrealistic. It wants to create a star-level magic weapon that can break away from the earth and rush into the starry sky."

Naya nodded, "That's true. But the starry sky is indeed very fascinating, so many young people in the magic department believed in this book and tried their best to create star magic tools. Naturally, they all failed without exception."

Rosen was secretly surprised when he heard this, but he remained calm: "It's always good to be willing to try, just in case it succeeds."

As he said this, he continued to look for a book.

I quickly found a book called "Research on the Limits of the Human Body". This book is very thick and contains basically no theory, but rather very detailed experimental records.

It not only records the limits of the body, but also the limits of the soul.

Most of them were discovered by the Republic of Nahuat in repeated battles with demons, and a small part was obtained from demons.

As for how the demons achieved the limits of the human body, that goes without saying.

All in all, this book is extremely valuable.

Rosen immediately flipped through the book page by page, and it took him 15 minutes to finish it.

With less than 10 minutes left, he chose to look through the only encounter with a level 19 demon in Nahuat's history.

It is also an extremely thick book, which almost perfectly presents all the details of the world-destroying war at that time.

The name of the 19th-level great demon Gao Miller was also deeply engraved in Rosen's heart.

Rosen flipped through the pages as quickly as possible, then pointed to the book "Studies on the Limits of the Human Body" and said, "I choose to copy this one."

Naya nodded in agreement.

On the other side, Zieglerana was also selected and sent for transcription.

Then the three of them left the Temple of Wisdom.

While walking on the spiral corridor leading to the ground, Rosen suddenly heard Naya's mental whisper.

"Master Rosen, I can see that you are very eager for knowledge of magic."

Rosen remained expressionless and replied secretly: "Of course."

"Perhaps you can consider staying in Nawat. As long as you nod, we will send someone to pick up your family, and all of Nawat's magical knowledge will be open to you."

Rosen had not expected to receive such an invitation, but he had already figured it out in his mind, so he politely declined: "Master Naya, thank you very much for your consideration."

"But I value not only my family, but also my people. I cannot go back on my promise to my people."

Naya's face showed a look of astonishment: "I understand and respect your choice. Once the book transcription is completed, you can go back as soon as possible."

There is a deep meaning in these words.

Rosen nodded immediately: "I will, Master Naya, and thank you very much for your reminder."

As they were talking, the three of them came to the ground.

Before she could stand firmly, Naya's communication device received an urgent message. She took a look at it and frowned slightly.

Rosen immediately asked, "What's the problem, Master Naya?"

"It's not a big deal. I have to attend an emergency meeting. You can take my Blackstone car back to Tranquil Manor and stay there. It's best not to go out easily. Everything will be discussed after I come back."

After saying that, she personally sent Rosen and the other man onto the black market car, and she herself got into another Black Stone car and left in a hurry.
