Of course, the knowledge obtained in this book is not necessarily accurate, because there are many descriptions of these realms, and these are the subjective assumptions of the writer.

In addition to these transcendent institutional frameworks, Adul also learned about the source of the energy that Muka had previously bound him.

According to the description in the book, there are many schools and variants of this energy, but in general it is called psionic energy, and the opposite is evil energy.

Under the subdivision of psionic energy are the more mainstream runes, the more niche arcane, and the most common natural energy.

Runes are short for rune energy, and no one knows where these runes come from, but there are many different schools and traditions that have been passed down to this day.

Arcane energy is more like a kind of leftover from runes, they are derived from runes, but few people will learn arcane energy, because it is derived from runes after all, and it is more complex and less effective than runes.

As long as you have a choice, you will not practice the arcane energy system.

Natural energy is the common natural elemental magic, which is also the most widespread and highly recognized power.

Professionals who wield this power are generally called mages, and they control the four elemental powers of earth, water, wind, and fire.

Of course, there are many natural energies on the Valoran continent, far more than these four, but due to Shurima's reasons, the owner of the book is unable to write about the remaining elemental powers.

For example, Freljord's ice, Freljord's thunder, and wood that has never been controlled by man.

The description of the evil power is also extremely brief, and it should have been cut or the author did not dabble in it enough.

After all, the books here are for students, and the college has more or less selected and sifted them.

Adur rubbed his slightly sore neck and slowly stood up.

Azir and Zelas went out for a while before returning to the library, but this time instead of saying hello, they chose to sit down at a table not far away to read.

Adul returned to the dormitory alone, and he already had some questions about Baff.

Sleepless nights.

The next day, Adul got up early in the morning, had a simple breakfast, and then went downstairs to wait for Muka.

After waiting for less than ten minutes, Muka also came to the downstairs of the dormitory.

Today, Mika seemed to have something bothering her, and her expression had lost its former vitality.

Adul really wanted to care about the favor of brushing Miuka, but Miuka simply taught Adur a few etiquette moves and left, saying that he would come to him in the evening after Adul met Baf.

Adul had no choice but to dispel his thoughts, and after practicing the etiquette taught by Muka a few more times, he went to Bafu's teaching room.

"Knock knock."

Adur knocked politely on the door, and Bhaf probably didn't expect Adur to come so early, but let Adur in.

Holding a book in one hand and a glass of dairy in the other, Barf was the first to break the silence between the two and said.

"Do you have an answer to that question?"

"There are some eyebrows, but there is one more question that bothers me before I choose, and I think this question may not be answered in the library."

Adur calmly answered Baff's questions, which Adur could still think of in advance.

Although Baf was not satisfied with Adur's words, and his face was a little worse, he still let Adur continue.

"Then tell me your question, and I'll see if you haven't taken the book seriously to solve your doubts, or if Shurima's largest library doesn't have the answer you want."

Listening to Baff's slightly sarcastic words, Adur knew he had said the wrong thing, but he still asked the questions he had prepared a long time ago.

"I've seen in the books that arcane is a derivative of runes, but many other books have different opinions and are vague in their words, can I ask you the real difference between the two?"

"You might as well ask me why 1+1=2 is such a stupid question. Runes are strong, arcane is weak, there is no arcane without runes, the difference is so obvious......"

When Barf heard this question, a touch of contempt appeared on his face at first, but he was suddenly stunned for a moment, as if he remembered something.

"Wait, you mean the difference between the two? That's what you mean? ”

Seeing that Baf finally understood the question that Adur wanted to ask, Adur was relieved.

This shows that this teacher should still have some ability, not the kind of teacher who follows the crowd and achieves nothing.

"I've heard a master say this question, and that master's blue body and smooth head are indeed unique, and I have some impressions of this question.

Although I don't understand very well, some of his words may be able to answer your questions.

Runes and arcane are like clouds in the sky and farmers on earth, water falls from the clouds into the world, and the farmer laughs. ”

Barf recorded the passage as he spoke, then handed the note to Adul.

Adur looked at the note thoughtfully, savoring what might have been a quote from Ruiz.

Ruiz is a rune master recognized by the Valoran people, and with the blessing of the world runes, he may already have the strongest combat power under the demigods.

At the same time, he is also the last rune keeper, and it is also his mission to recover and take care of the world's runes.

So if there's anyone in this world who knows the most about runes, it's Ryz.

Adur looked at the powerless Baff, and could only turn back and continue to think about how Ryz's words should be interpreted.

As it happens, there was another knock on the door.

Azir cautiously pushed open the classroom door and poked his head out to greet Mr. Baf, but was surprised to see Baf and Adur sitting next to each other with their brows furrowed.

"Hello teacher! Eh, friend, why are you here too, are you a new disciple of Mr. Baf? ”

"Your Highness! Manners! ”

Zelas whispered to Azir outside the door, in his opinion, this prince of his own family is really too worry-free, and after seeing acquaintances, he actually forgot all the etiquette that should be expected to face the teacher.

As a top scholar, Barf naturally has his own skills, and he is especially fond of the master and servant of Azir and Zelas.

But there was still Adur here, and Bhaf's handprint used the rune in his possession to seal Zeroth's mouth.

But Adur suddenly stared at all of this, and although he couldn't see it clearly, he felt something move from Bhaf's hand to Zelas's mouth.

This restrained Zelas's actions, which can be said to be exactly the same method used by Mukka to ban him.

"Mr. Baff, is this a rune?"

Adur asked curiously.

Baf nodded, realizing that he had been a little dismissive and rude to Adur earlier, so he replied kindly.

"That's right, this is the rune, your energy sense of smell seems to be very sensitive, how is it, do you have an answer to your question?"

"Well, I figured it out, I wanted to learn arcane."
