The General Library Building, also known as the Magic Headquarters.

Such a core building is equivalent to the Dark Moon Tower in the [Mystic System].

It is one of the most important buildings in the Knight Academy, with a comprehensive office, a library of secretarial documents, and high-level meetings.

Unlike other faculties.

In addition to the director and deputy head of the department that teaches and manages students, there is also a director and deputy director of the same level, who is responsible for managing the unique National Royal Knight College - Library.

At present, the person Demps wants to take Han Dong to meet is a high-powered deputy curator.

The exterior is designed to resemble the form of Big Ben, but it is different from the [Clock Tower], which controls the fate space, and the whole is surrounded by a strong magical atmosphere.

A pass authorized by Ms. Hera was presented.

The two officially entered the main library.

You'll first have to traverse a ten-meter-long passage filled with magical inscriptions that will further detect if the two are carrying items or if they are dangerous.

In the process, the crow mark on the back of Han Dong's right hand faintly emerged.

Combined with the perfect camouflage of the "Faceless Head", it successfully escaped the examination of these glyphs.

Demps on the side reminded:

"The main library building was designed and reconstructed by the former director, and for the first time it adopts a multi-dimensional 'staircase' structure, which is easy to get lost in the first time you come and follow me...... Otherwise, it will be difficult for me to find you again. ”

When the door of the detection channel is opened.

The wonderful structure of the hall of the library building made Han Dong stop immediately.

The staircase, which clearly does not conform to the rules of three-dimensional space, is designed in this open hall.

Some library staff in trench coats are walking the stairs in different directions.

As long as you grasp the rules, you can go to any area of the main library building.

If you look at such a ladder with a normal concept of three-dimensional space, you will inevitably be at a loss and get lost in it.

Due to the existence of the 'multi-dimensional ladder', the space utilization rate of the main library building is maximized and complicated.

Even if an outsider breaks in, if they fail to decipher the structure of the ladder in the first place, they will be lost and unable to reach any important areas, giving security personnel time to move.

"Penrose-Stairs?"

Han Dong had come into contact with such a multi-dimensional model before his death, after all, sometimes it was necessary to perform micro-scale calculations, and Han Dong's mathematical skills were not bad.

In basic mathematics, there is the concept of multidimensional space.

But this is only to help mathematicians understand the concept of multidimensional space, and it is difficult to apply it to the field of physics...... After all, human beings are only individuals in three-dimensional space, and it is difficult to spy on the structure of high latitudes as low-latitudes.

"If that's how it works...... Centered on the turning point of the staircase, four perpendicular lines could theoretically be made, which is true in the way these people walked.

A stepped design that projects a four-dimensional space in a three-dimensional space.

Former Curator...... Is it so powerful? ”

Seeing Han Dong on the side, he looked thoughtful.

Demps asked curiously, "Smack!" Nicholas, is it difficult for you to have some insight into multidimensional space? ”

"I just know some one-sided concepts, not opinions."

"It's already very powerful...... the difficulty of "spatial science" is much higher than that of regular magic.

The level of space entry alone can screen out 99% of the trainee knights, and the follow-up learning is even more difficult.

It's been a long time since the Holy City has given birth to a commander-level space mage.

I am currently taking time to learn about and learn about "spatial studies". ”

There seems to be something hidden in Temple's words.

Han Dong asked with some curiosity:

"In other words, aren't there some beings in the destiny space who are proficient in space ability?"

"They are just born with intersections with multidimensional space, and they are not proficient. The spatial abilities they carry are endowed with them, not learned on their own...... Most of them don't understand how it works.

Space mages in the true sense of the word are basically impossible to kill, and even high existences.

Let's go, we can't keep Lady Hera too waiting. ”

The moment he stepped on the stairs, Han Dong felt that the normal library hall had become 'folded', and the seemingly simple stairs could easily span a large span, and he could reach any area of the library building at will.

Constantly turning back and walking longitudinally.

A staircase hanging diagonally on the wall corresponds to the Third Reading Room

Once you enter a room in the main library.

The interior immediately returned to its normal three-dimensional spatial structure, and in the reading room with a total height of about 10 meters, more than a dozen pairs of white gloves were sorting out the books here and cleaning them by themselves.

Some of the older students are spending their precious time studying here.

Led by Demps, find Lady Hera in the deepest part of the reading room.

A blonde beauty wearing gold-rimmed glasses, with a beauty temperament similar to that of a movie star, and looks about thirty-five years old from her appearance alone.

But his figure and skin texture are definitely comparable to some models in their early twenties.

"Oh...... Are you a student of Mr. Black and White? Follow me. ”

Hera flicked a special switch and opened a hidden staircase to the private office of the deputy curator.

"Sit down."

Lady Hera deliberately sat Demps next to her so that her long legs could be crossed over Demps's body.

Han Dong, on the other hand, sat on the guest sofa.

"I heard you want to mint in [Library]? Have you invested the relevant points? ”

"Hmm...... 3 points have been invested. ”

Hera was a little surprised, she thought that Han Dong would ask about the feasibility before investing, but she didn't expect that she had already put in the important 3 points.

"Oh!? Three...... Not bad! Do you plan to study primarily in the Department of Mystery in the future, or do you spend most of your time in our library? ”

This is a question that needs to be answered with careful consideration.

"I can do both, but because the library started too late, I will stay in the [library] as much as possible to study in the early stage."

For Han Dong's answer, Hera's expression was more indifferent.

"If Demps hadn't asked me to 'take you' in...... You are such a hot potato, no teacher in the library will touch it. You know, while minors are not completely forbidden, they are not encouraged at all.

Because the minor distracts fate points and energy, in the end, students who can't pass even the most basic knight exam abound.

There are two conditions for studying under me as a full student. ”

"Deputy Director Hera, please speak."

"First, if you really have the ability to spawn a unique talent tree like the Great Plague Chief.

I need you to explain at the Knight Commendation that I am the only tutor for your minor, and I have been of great help during your library studies.

Second, the long-term pass I have given you to apply for only means that you belong to a 'visiting scholar', and you will have much less power than the students in my department.

However, since you have such a good relationship with Demps, you can also ask him to help you with some things that you can't do.

I heard that Mr. Black and White is very optimistic about you, and it is also good that you communicate more privately with Demps. ”

"Row ......"

In fact, Ms. Hera's request is simply that she will not let Han Dong study secretly in the library on the basis of not justifying his name.

If you have any achievements in the future, you have to say that you have received great favors from the library, and admit that you are a trainee knight trained by the mysterious department and the library.

However, it is already a very good result to let Han Dong get a long-term pass, and the follow-up things can be considered slowly.
