The white rock prism is inclined to the spire, and the maze of books follows the edge.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The Holy City, in terms of its size, is nowhere near the size of an industrial city, and there is only one building called the Library in one of the most spectacular cities of our time, located in the core of the city. It is an undersea structure made entirely of some kind of white rock, and it is said that even after only a few simple renovations from the establishment of the Holy City thousands of years ago to the present, it is definitely one of the oldest artifacts.

From the outside, the library is in the shape of an elongated polyhedron that rises diagonally on the ground, gradually widening from the section of the ground, reaching the limit of its width in the air and then gradually shrinking and finally converging into a sharp vertex, while the overall outline looks like a slender white crystal slanting into the floor of the Holy City, giving the impression that part of the library's structure follows the contours of the whole and extends into the ground.

Of course, even the library of the Holy City was flooded with sea water like the rest of the buildings of the Shiokai people. The Shiokai can be separated from the sea for a short time, but this is like letting the Moon Prayer Dive into the sea is a short action of holding your breath, and it is impossible to stay in this state all the time. Therefore, it is obviously unrealistic to use paper books to preserve information in an environment completely flooded with seawater, and ordinary paper will quickly rot and be destroyed. At the same time, because of this environmental problem, it is impossible for the people of Xihai to write information normally in the sea water with pen and ink, and if all the books in the library are stored electronically...... So what else is this library going to do?

The girl named Xiaoxi stopped in front of the building that looked quite impressive in the near distance, looked up, and vaguely seemed to hear the words that had been spoken when she had been here......

"Big liar, I've asked the other students what kind of secret place the library is! Teacher, you were obviously deliberately deceiving people before, right? ”

"Now, this is not a joke, when you have learned all the knowledge of the first year, the teacher will take you to the secret base in the library."

"Eh, is there really a secret room? Aren't you really lying to me this time? ”

She looked up at the white building in front of her with a faint smile, until the light of the artificial sun in the sky made it impossible for her to look directly at the high spire anymore, and vaguely she seemed to understand why there were lighting devices everywhere in the Holy City, but many Xihai people still liked to go out into the street to feel the light of the artificial sun.

Ten years, one hundred years, one thousand years...... From the past to the infinite future......

Perhaps compared to the bases that have been operating for hundreds of millions of years and can constantly maintain themselves, this nuclear fusion reactor that has only been in operation for thousands of years is nothing, but for the people of Shiohai, whose natural lifespan generally does not exceed two hundred years, this artificial sun, which has been shining over the holy city for thousands of years, is as deeply rooted in the hearts of the people as a real miracle. The faint white light bears witness to the development of the city, from the humble frame on the barren seabed to the holy place where countless people from the Xihai Sea come and go today, this is a chapter in history.

Although this seems to have no scientific explanation, emotions are such a thing, just like the ancient scale sculpture in the square, these monuments that have become a microcosm of history themselves can clearly feel the breath from ancient times.

She retracted her wandering thoughts and checked the small bag at her waist...... In fact, her behavior will not attract any attention at all, and many Shiokai people will be in a daze in front of the library every day, which seems to have become a special local landscape. Now, the girl naturally knows that the place where no one came when Teacher Sugi said at the beginning definitely did not refer to the library itself, as a landmark building in the Holy City, there are definitely a lot of Xihai people coming and going here.

Different from the Moon Prayer Man or the Xinyu Man, the evolution of the Shiohai people in terms of body genes is more alternative, because of the exoskeleton structure of systemic protection, they naturally do not need to protect their bodies from environmental damage through clothing, so the Shiohai people actually do not need clothes, and the exoskeleton structure of their outer body has played a protective role. However, some decorative or functional things still exist, such as waist bags to store personal belongings. Of course, unlike the Moon Prayers, the Shiokai do not need any help to secure the wrapped things, and the gaps in their own carapace can be firmly stuck in the strap under conscious control.

Xiaoxi took out the student ID card of the Holy City from the waist bag she was carrying...... This thing can also be used as an ID card in this library, and she walked to the library entrance, and as she walked through the entrance, she placed the card near the scanning device next to it, and a door on the wall in front of her that looked like an elevator entrance slowly slid open.

That's right, the entrance to this library isn't a fully open door as many people think, but is made up of many elevator entrances, and the interesting part is that you will arrive at one of dozens of random entrances, and most of the time newcomers won't be able to figure out where they are.

"Welcome to the Holy City Library for the 18th time this month, Xiaoxi."

When the entrance door, which could only be entered by one person at a time, slowly closed at the rear, a gentle female voice sounded in this small room with an interior similar to that of an elevator, and Xiaoxi was no stranger to her.

"Good day, Miss Bai Yu." Even though she knew that the other party was not here at all, Xiaoxi responded politely to the wall in front of her.

Contrary to what most people think, the Holy City is not really a serious place, but a place full of interesting things. It is said that this tradition was passed down from the first students of the Holy City, who completed their studies and participated in the expansion of the Holy City, and it seems that the ancestors of that group of ancestors were ...... Some of them are out of line, so much so that they have left all kinds of strange black history for future generations, such as the gates of the Holy City, which are changed every month, the floor tiles on the square that have been engraved with code symbols since they were first built, and even the very incomprehensible and out-of-time shape of the Holy City Library is also the handiwork of the original group of Holy City students.

In this case, there seems to be nothing strange about some of the urban legends circulating among students. One of the most famous urban legends is about the librarian of the Holy City named Bai Yu, who is a very enthusiastic and righteous female Shiokai person, but no one has ever seen her true face...... Although every student who has been to the Quds City Library has heard her voice, and even has access to her help.

No one knows how old Miss Bai Xi is...... Even this is what she asked her students to call her, and all that is known is that the mysterious librarian never seems to be old, and that the grandparents they know also studied in the Holy City Library with the help of this administrator. She seems to know everything about the location of every book in the library, and is able to communicate with several students at once. One of the most reliable and popular speculations among students is that Miss Bai Xi is actually the artificial intelligence responsible for managing the library.

Of course, this conjecture has never been directly confirmed, and every time a student tries to ask the truth of the incident directly, Miss Bai Xi will smile and refuse to answer: "This question is forbidden!" ”

Of course, one of the reasons why the AI speculation is not completely confirmed is also because Miss Bai Yu's performance is too human, completely different from most of the intelligent service robots in the Holy City, and she even cares a lot about some sensitive issues...... For example, whenever a student asks her age, she always replies with a weird smile, "Ah, I'm a 17-year-old girl." Or she is unexpectedly sensitive to her own name, and she can't tolerate others mispronouncing her name, but her name is easy to be mispronounced......

But at this time, Xiaoxi didn't think too much about other things, after her greeting, the completely closed cabin began to move, and she closed her eyes and carefully sensed the direction of the cabin's movement, front, left, up, right, front, left, down, front......

Eventually, when the cabin had completely stopped moving, she opened her eyes again, and the direction of movement she had just remembered was quickly compared with the map in her memory, and she looked confidently ahead: "Entrance 6 of the North Zone." ”

"Clever boy, it looks like the labyrinth entrance to this library is about to lose its effect on you." Miss Bai Yu's voice rang out again from the hidden speakers around her, and at the same time, the door in front of her slowly opened, revealing a narrow passage full of protruding and sunken lattices, "Good luck then, Xiaoxi." ”

Xiaoxi took a few steps forward and left the confines of the chamber, the door behind her quickly closed again, and she looked into the library in front of her, the uneven circular passages were like passages in the space station, extending irregularly in every possible direction, and if you looked closely, you could see that the floor, walls, and even the ceiling here were made up of countless square boxes of exactly the same size, which were sometimes concave and sometimes protruding.

There's more to the Al Quds Library than just the strange librarians, because in the seawater immersion environment, it's certainly impossible to keep the books neatly on the shelves like the terrestrial libraries. The pages are all made of a special plastic, and the books themselves are made into uniform-sized sealed boxes that can be connected to each other by embedded magnets. The entire passage inside the library is made up of countless books connected together, which is really random and irregular, and the borrowed books are returned to wherever they can, after generations of students have repeatedly tossed and turned, the interior of the library has completely become a labyrinth of books, and it is said that many personal belongings forgotten by students are missing. So, with the acquiescence of the teachers, it was eventually made into a place full of adventure, and even the location of entry was changed to a random entrance. It's not that no one thinks of marking the entrance, but there are still some who like to remove the mark......

This is the rather wonderful labyrinth of books in the Holy City Library.

(Na, the update speed of this book is often not because I am too lazy to code words or have no time to code words, but because the plot development speed can't keep up.) Therefore, it is useless to try to urge by rewarding, and the update speed is irregular, and it is completely casual to say~)
