Later, Zhao Xu and Antinoya talked about the entire process of mastering advanced abilities, especially the fact that he made an oath to the "Origin of Magic" until death.

Antinoya didn't say much, but went over to the desk and opened a "borrowing certificate" for him to find the answer on his own.

After Zhao Xu regained the spell slot the next day, he took the parchment "borrowing certificate" that Antinoya gave him, and began to go to the destination "Legendary Library" recorded on it.

Compared to the Knowledge Library, which is a library that enriches and improves skills and knowledge, the "Legend Library" has no record at all.

Zhao Xu looked through the new mage's guidebook, which recorded the location of most of the buildings in the Floating City, and the "Hall of Truth", the core area of the Floating City, was not shy about it.

The obelisk in the corner of the Floating City is also marked, but with a simple name and a ring indicating extreme danger.

But the "Legendary Library" seems to have never existed.

Zhao Xu followed the route in his memory, and after spending about twenty minutes, he finally walked to the only place indicated on the "borrowing certificate" - the Knowledge Library.

The knowledge library occupies an extremely wide area, and Zhao Xu has only borrowed books on the bottom two floors before, and the upper floors don't need to be touched at all with his current knowledge and skill level.

However, this time, the place pointed to by the parchment was the highest floor of the "Knowledge Library", and Zhao Xu also entered the alchemy elevator for the first time.

As the gate opened, Zhao Xu walked inside one step at a time, and when he was about to press the button on the highest floor, which is the tenth floor, his hand stopped.

There is no tenth floor!

Zhao Xu took out the certificate from the new one at this time and looked at it, and found that although the antinoyana flower font on it was very elegant, it was also extremely clear, it was the tenth layer.

Zhao Xu sighed, feeling some pressure.

Ever since he had experienced the last time he had experienced the vanishing Classroom 101, he had understood one thing.

But wherever Antinoa didn't take him, there were usually checkpoints waiting for him.

However, Zhao Xu still didn't hesitate too much, and pressed it on the brass hollow layer button - nine layers.

babbling in the alchemy elevator, accompanied by the sound of ratchet dragging, Zhao Xu slowly rose with a slight sense of overweight.

At this time, he also took out the "New Mageman's Handbook" and flipped through it, until he turned to the introduction page of the Knowledge Library.

Zhao Xu looked at the content of the record on each layer, and suddenly frowned.

"Boom." At this time, the elevator slowly crashed into the space on the ninth floor, and the gate slowly opened after touching the mechanism.

Zhao Xu also walked out at this time, and in front of him, there were countless rows of heavy wooden bookshelves, on which the classics of knowledge were neatly stacked.

The only thing that's a little strange is that the books are covered with a thick layer of dust, as if no one has touched them for decades.

Moreover, an additional metal iron frame was added to the cover of each classic, and a lock was hung in the opening and closing position.

That is, every book on knowledge here is locked.

This floor is completely different from the number of floors below, and there is no front desk for book borrowing and examination qualifications.

And after Zhao Xu walked out of the elevator, the gate of the alchemy elevator also slowly closed, and at the same time, the brass button on the ninth layer also slowly disappeared, as if it had been directly erased.

Zhao Xu looked at the booklet in his hand, shook his head, and stuffed it back into his backpack directly.

The pamphlet reads - The Library of Knowledge, with eight floors.

What happened to the ninth layer of the thin air that he came from?

At this time, Zhao Xu also noticed that the borrowing certificate written by Antinoya to him, those words had disappeared little by little, as if they had been used.

Zhao Xu immediately became vigilant, and at the same time began to think about the current situation.

Is this layer in front of him just the ninth layer of the void, or is it the tenth layer where his destination is located?

And the only thing he can be sure of is probably the "borrowing certificate" that Antinoa gave him to get to this abandoned floor.

Even he doubted that when others entered the elevator now, they would not be able to see the brass button of the "ninth floor", otherwise this booklet would have been questioned a long time ago.

At this time, Zhao Xu first released a "protection against evil" spell for himself, and then walked forward.

With the Cloak of Stars, he wasn't so worried about melee attacks at the moment.

At this time, Zhao Xu approached the first row of bookshelves and directly took down a locked book.

Zhao Xu barely crossed the metal frame and made out the title of the book, "Ritual of Evil: The Dinner of the Undead", and in the center of the painting was a group of skeletons with a strange red light, dancing around a bonfire, and above the bonfire was an adventurer with a terrified expression.

Zhao Xu stuffed it back directly, and took out another classic book to read, "Stealing Life, A Hundred Ways to Suffer".

Zhao Xu suddenly skimmed through the past in a whole row, "The Sacrifice of the Witch", "The Ten Forbidden Rituals of the Wilderness", "The Lich's Life Box", "Blood Sacrifice Curse, Family", "How to Become a Demon", ......

He shook his head suddenly, looking at the books that were not good.

Thinking of this, Zhao Xu walked directly to the second bookshelf.

After some browsing, he was on the third shelf.

In the end, Zhao Xu already vaguely understood.

On this floor, there is an abandoned and forbidden library, where all kinds of evil rituals and vicious curses are displayed.

Zhao Xu knew that there were also spells of an evil nature in the spells, but looking at these classics, the methods involved were also more primitive and cruel.

It seems to be a way to survive in the uncivilized era.

Suddenly, Zhao Xu frowned.

On the wooden board on the far right of the bookshelf hangs a string of keys that have slowly rusted.

Zhao Xu directly took off the set of keys and looked at them, and found that the handles of the keys were all of different shapes, many of which were skeletons and even demon heads.

And there was also a line of fine carving on the portrait, Zhao Xu read it with wide eyes, "The structure of the inferior demon".

Immediately, he realized that it was the name of one of the classics on this shelf, and the cover of that book was a bad demon at that time, which almost disgusted him.

In other words, this key corresponds to the metal lock frame on the outside of which classics?

Zhao Xu directly took out the book, looked at the structure of the key, and the hole shape of the padlock in the middle of the book, which was indeed very consistent.

Zhao Xu gently inserted the key in, and then twisted it.

"Tick." Bang.

The lock is open.

However, Zhao Xu immediately twisted back in reverse and re-locked the iron frame that locked the classics.

Suddenly, Zhao Xu seemed to feel a sense of vibration from the book "The Structure of the Bad Demon" in his hand.

However, Zhao Xu directly stuffed the classics back to their original positions.

"Young man, you are indeed cautious." An old voice came from behind Zhao Xu.

Zhao Xu was almost frightened and turned around to cast a spell.

However, he immediately regained his composure, and turned his head to see that it was an elderly mage who was already old enough to use a cane, and he was looking at Zhao Xu with his back bent, his eyes were full of cloudiness, as if he was about to rot wood.

It was completely different from the mages that Zhao Xu had seen before, who were still full of energy and vitality despite their old age.

"May I ask who you are?" Zhao Xu asked, but in private, he was ready to take out his protective staff.

"Don't be nervous, I'm really going to do something to you, you can't pull out the thing you put in your backpack."

The old mage said, coughing uncontrollably.

"How do you know I'm going to dig something?" Zhao Xu asked for advice at this time.

"Your movements and demeanor are too obvious." The old mage said with a smile, but the skin on his face was already wrinkled, and his laughter was a little hoarse.

After hearing this, Zhao Xu relaxed.

He nodded, he really should fix those redundant movement habits in the future, otherwise he would not be able to hide the words and color observation skills of these mages.

"Let me introduce myself, I'm Morton, the grave keeper of this 'abandoned library.'"

Abandoned Library?

Grave keepers?

Zhao Xu suddenly noticed the strangeness that the old mage said, but he still waited patiently for the other party to continue.

At this time, in the entire library, only the voices of the two of them echoed, which seemed a little eerie.

"Curious? Why not the forbidden library or something like you guess? Rather abandoned? ”

After that, the old mage looked back at the field that was 100 meters deep and stacked with hundreds of bookshelves, "Because the books here are all outdated. ”

Zhao Xu also began to understand at this time.

It stands to reason that the more evil and terrible things are, the more people who are dead will read them.

Zhao Xu is not interested in some ways that need to be obtained by sacrificing others and sacrificing others.

But for some, these forbidden and terrifying ritual magics are amazingly fascinating in themselves.

So on this level, it's a little strange that there are no half living people.

"It's mostly old rituals that have been handed down, and many of them are no longer valid, but that's not a big problem in the first place. Mainly, these texts, most of which have some kind of curse effect that will affect those who read them, are all sealed here, waiting for the years to be abandoned. The old mage recalled.

"Excuse me, Master Morton, do you know how to get to the Legendary Library?" Zhao Xu humbly asked for advice at this time.

"Hehe, it's really funny, it's actually a level 3 mage like you who wants to go to the 'Legend Library'."

The old mage couldn't help but laugh out loud at once, making Zhao Xu a little worried about the other party.

Suddenly, the old mage's laughter stopped, and he looked at Zhao Xu, "The entrance to the legendary library is in one of the books here. ”
