Although he didn't know the specific reason, but using his brain to guess, Zhao Mu also roughly knew that his sudden extra identity as a librarian must be related to his ability to show.

This sudden extra identity made Zhao Mu very happy, which would provide him with great convenience and allow him to acquire more knowledge in a shorter time.

Librarian, this is the most awesome profession in the legends. In this profession, there are too many awesome characters who are single.

In ancient times, there was Lao Tzu, the ancestor of Taoism, Sima Qian, who wrote the "Historical Records", and now there is Taizu, who created a new China, and Bill Gates, the founder of Microsoft...... All of them are legends.

Zhao Mu deliberately verified his rights as a librarian, and the result surprised Zhao Mu.

Facts have proved that with this identity, Zhao Mu can walk into the library to consult materials almost at any time, whether it is day or night, regardless of whether the library is open to the public or not.

Not only that, Zhao Mu also found that with this identity, many books that could not be borrowed before can now be borrowed by himself.

Zhao Mu didn't know that his authority as a librarian was much greater than that of a normal librarian.

The general librarians are basically the faculty and staff of the school, and their administrator authority is restricted in many places, while in contrast, Zhao Mu's administrator status is restricted in very few places.

As a librarian, Zhao Mu is not aware of a hidden rule of the library, which is also a rule that only a few people know, even the librarian does not know.

This unspoken rule, which is not clearly documented, only exists in the minds of a few people in the know. Those who should know will know, but those who should not know will never know.

This hidden rule is made a third-level borrowing permission by insiders.

The three-level borrowing authority lists the materials of the Imperial Capital University Library into three levels, and the corresponding permission can only borrow the books and materials of the corresponding level.

The Imperial University Library is one of the top five in East Asia, and it has a wide range of books and materials.

Among the vast number of materials in the library of Imperial Capital University, there are many precious materials that cannot be disclosed even if they are listed in the confidential archives, and it is only natural that the three-level borrowing privilege is proposed.

Among the three levels of authority, the first level of authority is the highest and enjoys the greatest rights, and the third level of authority is the lowest and enjoys the lowest privileges.

The third-level authority corresponds to all students, faculty and staff of Imperial Capital University, as well as those who have applied for a library card outside the university.

It can be said that the vast majority of people who have borrowing rights have third-level permissions.

With third-level permissions, you can already borrow most of the books and materials in the library, which is completely enough for most people.

Level 3 permissions, you can't borrow books and materials above the permissions.

Similarly, books and materials above the third level cannot be found on the shelves of the library, which are open to the public, and they have their own place.

Not only that, if the permission is insufficient, if you search for books and materials outside the permission in the library's computer system, the books will have been borrowed, and even the corresponding book information will not be searched.

Above the ordinary Level 3 permissions, only a few people have the Level 2 permissions, and can borrow all books and materials, including the ordinary Level 3 permissions and other Level 2 permissions.

The materials corresponding to the second-level authority include some rare ancient books, some important documents that are not open to the public, and some important cultural relics.

Compared with the materials corresponding to the third-level authority, the books and materials corresponding to the second-level authority are obviously more than one grade more valuable, and these are important things that ordinary people cannot access at all.

For example, most of the details of the current frontiers of science and technology, including the important research results of many national scientists, these many things cannot be measured in money.

And the highest level of first-level authority, there are only a handful of people in the entire Huaxia who have such authority, and these people are all big people who control the fortunes and direction of Huaxia's national movement.

The information corresponding to the first-level authority is all top-secret information that has been tightly sealed, or something that can be called the first-level national treasure of Huaxia Town.

This kind of information is not at all something that ordinary people can access, and as long as ordinary people make a tentative act of snooping, they will be detected in a very short period of time, and even monitored by state forces.

What Zhao Mu currently has is the second-level authority that only a few people can have in the third-level authority.

At present, Zhao Mu doesn't know a lot of the inside information, but he feels that his luck has been really good recently, and he has applied for many times before, but the books and materials that have been borrowed are easily borrowed by himself.

Level 3 authority, with level 1 higher than level 1 important authority. Within the authority, you can borrow the books and materials you need at will, which is a huge force that is not obvious.

Don't have permission, but want to borrow more books and materials?

There is also a way, in such a case, you can apply to the corresponding person in charge.

However, the application process is a very complex process, and the difficulty is high enough to discourage many people, and it will never be easy to apply without necessary circumstances.

Compared to the huge difficulty of applying for a skip level loan and the long process that usually takes at least a month, the large level of permission is undoubtedly a huge difference between heaven and earth.

All of these are hidden and invisible rules, but they really exist in every corner of the library.

It was precisely because this rule was hidden invisibly, this perfect disguise, and Zhao Mu had never thought of this, so even Zhao Mu's now smart brain did not notice anything unusual from it at all.

However, although he was completely unaware of all this at the moment, Zhao Mu had already begun to enjoy the huge benefits brought to him by the second-level authority that was above the third-level authority.

In the past few days, Zhao Mu has successfully borrowed a number of high-end scientific and technological materials, including the latest research results of several famous academicians of the Chinese Academy of Sciences.

These high-end scientific and technological materials correspond to the scientific and technological inheritance of the imperial civilization that he has learned, so that Zhao Mu has gained a huge harvest in a short period of time.

The wisdom of the top scholars in China cleared the confusion of knowledge for Zhao Mu and pointed out the way forward, and this kind of help was undoubtedly very great for Zhao Mu.

Indulging in the mysterious and wonderful ocean of knowledge, Zhao Mu easily forgot the passage of time, and did not know that the Imperial Capital University had officially opened without realizing it.
