The fingernail-sized mental trail brought Freya only a short piece of information about the original necromancer's escape, and it was still very incomplete.

Even so, though, Freya can analyze useful information from there.

Of course, if Freya herself knew one or two prophetic spells, maybe she would get more, after all, the essence of a wizard is spiritual power, and even the traces left over the years can understand many things.

He rested on the ground for a while, and only got up when the cyan runes under his eyes slowly dissipated.

This method of direct brain analysis is simple, but it also has a certain price, which is the phenomenon of Freya just now.

It's just that what Freya didn't expect was that this price actually reached this kind of Cheng dù, even if she was a great knight, she couldn't compete with it.

Shaking her head slightly, after feeling the abnormality of her sight disappear, she tapped the desktop, a little light flashed, and the carved rune circle suddenly disappeared on the desktop.

Looking at the mess on the platform and the ground, Freya frowned slightly and shouted towards the door.

"Anna! Anna! ”

Soon there was the sound of hurried footsteps outside the door.

The door clicked open, and a tall girl dressed in a maid's outfit walked in.

"My lord, what do you command?" She said respectfully.

This was one of the lady-in-waiting that the countess was destined to her.

Freya took out a white silk scarf and wiped her hands.

"You clean up here, burn the contents of the trash can, and don't touch the long-tailed rabbit in the wooden box for half an hour, understand."

"Understood, sir." Anna whispered.

"Hmm." Placing the silk scarf in her hand, Freya put away the key on the table, hung it around her waist and walked out of the room......

Early the next morning. A black carriage slowly departed from the manor and headed in the direction of the castle.

Freya, dressed in a white robe, sat quietly in the carriage, holding a slender black key in her hand. At this time, the dense green light formed small hands that kept eating away at the key.

Freya, on the other hand, frowned slightly and stared at the key in her hand.

For a long time, she waved her hand casually. In an instant, countless small hands stumbled away.

"It's not any material I know, but it's like a synthetic one, and of course it may not belong to this world." She muttered under her breath.

Most of the analytical power of the technique is based on the energy type, size, mass, density and other external factors of the object, and finally the results are obtained through the knowledge in the mind of the practitioner.

Although it may not be as good as the analysis circle in terms of analysis ability and mental power consumption, Freya is still sure that this thing is not something she knows.

"But since Angelia has information there, it's not in a hurry."

For the clues of the necromancer, pass guò that brief fragment. She had already vaguely guessed a place, but she still needed something and time to confirm it, and if she went rashly now, she might still be startled, which she didn't want to see.

Fifteen minutes later.

The carriage enters the castle of Raymond City.

The countess did not seem to be present today, and did not come to meet her, but everyone in the castle had been informed of Freya's honorable status.

Of course, it was not a wizard, but a high-profile official.

And all the people in the castle, Freya can be transferred.

Led by a close count of her friends, Freya went to the castle's library.

The large library was filled with the faint smell of ink. Although the countess gave up her knowledge because of her rights, as a family with a solid background, the amount of knowledge in this library is still considerable.

Freya, who walked into the library, randomly pulled out a book from the shelf. This is a book that describes a brief history of the empire and the major families.

It wasn't what Freya was looking for, but she read it carefully.

All the knowledge is not much different for Freya, except that it is divided into two categories: ordinary people and wizards.

However, any kind of knowledge has its usefulness, and even ordinary people may be useful in special situations.

So, whenever she has the opportunity, Freya will draw on them to enrich herself.

Knowledge makes her progress, and it is what all wizards seek.

The gentleman and old man I saw for the first time during this period had come and wanted to say hello. But seeing Freya concentrating on reading, she left without bothering.

Two hours later. Freya put down a miscellaneous notebook in her hand, then pulled out a book with a black cover.

Only when her hand touched the book. Suddenly she felt a tingling pain in her fingertips, which made Freya withdraw her hand suddenly

'Smack. ’

The book fell to the ground.

"Huh?"

She looked at her fingers, and a black spot the size of a pin's eye faintly appeared on the tip of her finger, and a drop of blood slowly spilled out.

"You can actually break through my defense field and directly act on *?"

She looked solemnly at the black book that had fallen to the ground.

The cover of the book has no name, it is just pitch black, and there is not even the author's signature.

The surface of the cover was pimpled, like the untreated skin of some kind of creature, and in her psychic sense, the book itself seemed to have some inexplicable force field.

"Is this a wizard's auto-protection spell?" She frowned slightly.

Obviously, this nameless book belongs to the wizarding world.

After a pause, Freya crouched down and slowly stretched out her hand.

The blue eyes stared motionlessly at the black book that fell to the ground.

"Visible!" She suddenly said a word.

The white palm suddenly ignited a green flame.

The flames burned silently, and there was something eerie about the reflection on Freya's side face.

Her eyes narrowed slightly, and Freya slowly pressed her hand towards the book.

'Hiss...'

As soon as the cover touched the green flames, it hissed, and in the midst of the cautery, a white grimace spider suddenly appeared in the middle of the originally empty black cover.

The spider seemed to be painted, but it was like a living creature trying to crawl to the back of the cover, as if it was afraid of Freya's green fire.

However, he was directly pinched by Freya in his hands.

The green flames directly caused the spider to burn violently, making a crackling sound. After a while, a pile of black ash appeared on the surface of the cover.

Looking at the ashes, Freya waved her hand. Disperse the flames.

Then pick up the dropped book.

The stinging pain didn't come, and the black cover changed completely.

A large number of dense black eyes emerge from the surface. It's just that these eyes are closed, and none of them seem to be alive.

However, it was all real in Freya's touch, which made her feel sick.

"There are people who use the skin of a hundred eyes to make a cover, although it can be conducive to the preservation of books, but this author is really a bad taste!"

Flipping through the book with a grumbling mouth, Freya realized that it seemed to be a record of a wizarding organization.

The contents are all illustrated books, but with Freya's knowledge, she can understand some of them. But there are many more that have never been seen before.

Flipping the pages slightly, Freya frowned slightly.

"Most of the things on this don't belong to this world, and the organization itself that comes to this material involves a large area, and it may belong to a first-class large-scale wizarding organization."

There wasn't a lot of information, and just as she was about to turn to the last few pages, an illustration suddenly stopped her.

It was a pattern of a string of black keys.

Connected by black circles, there are more than a dozen.

And the appearance is the same as the touch on her waist.

"The Key of Mystery...?"

Unfamiliar words made up of several letters appeared in her field of vision, and next to them were notes.

'The origin is unknown, the time and place of appearance are random, and the key that can open the door to the world. Each key is different, and the world is different'

The note was only one sentence, very brief, but a little shocking to Freya.

Can travel through the world? What a concept it is. I didn't expect the key to be found at random to be such a magical thing.

This made her subconsciously touch the key on her waist.

Each world is very different, and if you want to travel through the world, in addition to the known spatial rift, the only way to do it is to use the world stone monomer to teleport.

It's just that the spatial rift is regarded as a valuable resource handle by some large wizarding organizations, and although some small organizations also have the World Stone, the teleportation of this thing is monolithic, and the unknown location of the world is random.

It was almost used as a form of punishment for exile.

And now the 'key to the mystery' she has obtained can be said to be the most precious thing in a certain way.

"I just don't know how to use this key, and what the World Gate is...", she sighed a little.

But. Even if you don't know it for the time being, you can't bury the value of this thing.

Let some excited feelings slowly calm down. After turning the next few pages, she applied a defensive circle to the book before stuffing it back into the shelf.

Since the book was discovered here. Then the countess may know something about the origin.

Perhaps because of this key, Freya was not in the mood to continue watching.

After flipping through a few random copies, just as she wanted to leave, there was a sudden noise outside.

Running figures could be seen faintly outside the half-open door.

And a strong smell of blood came.

This made Freya startled slightly, and then strode out of the library.

The maids in the castle were busy with something, and they all looked anxious.

Freya asked in a deep voice as she reached out and grabbed a maid who was trotting beside her.

"What's going on?"

The maid originally wanted to break free, but when she saw Freya's face, her body shook slightly, and she said with some urgency.

"My lord, the lord of the city is injured, and I'm about to go to see Dr. White."

"Wounded?" Hearing the maid's words, Freya raised her eyebrows, let go of her hand and said, "Okay, then you go." ”

There was no reply, and the maid made a simple salute and hurried away.

Freya watched thoughtfully as the maid left.

Although she didn't do it, Freya could also see that the countess was almost the strength of the middle level of the Great Knight.

Of course, this level can only be said to have been reached, and I don't know if there is a sense of qi.

However, being able to wound a great knight seems to be a big deal for Raymond City. (To be continued)
