Transpose the ancient stone slabs, and the deep secret room is recorded in the world.

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

Thousands of years have passed, and the inner workings of the original Quds Library have long since become a secret that no one knows. The uniform-sized books are like bricks that create these passages in all directions, creating a complex labyrinth throughout the interior of the Quds City Library, and it is not just a static labyrinth, and even now, the students who come and go are constantly changing the topography of the labyrinth...... This also means that even the first and second volumes of the same book may be placed more than a few hundred meters apart, and even the height difference is very large.

This labyrinth of books is exactly what the original designers wanted to achieve. Not only are there a huge number of books of all kinds, but there are also many personal belongings left behind by former students, some of which were accidentally forgotten and too lazy to find while reading, and some of which are ...... Those gadgets that suddenly make ghostly noises when someone passes by are not accidentally lost inside.

This unique and adventurous design has succeeded in attracting many Shiokai people who were not happy to run to the library, and just like the appearance, the library is indeed bigger than a building on the ground. Special materials and completely sealed packaging allow these books to last for hundreds of years without using them, and those damaged books are also remade during special maintenance work, so the books that have been piled up over thousands of years are so large that the underground part of the library is far more extensive than it feels, and even occupies a large area of the core of the Holy City.

If you don't have a clear goal, the people of Shiokai who come here can roam this huge sea of books in this library in a casual way...... Of course, if you need to find the books you want, you can't rely on this method completely, so you need to seek the help of the librarian, Miss Bai Yu. She seems to be able to search for the location of any book you need to look up, and can also directly list the candidates for classification, which is one of the important proofs of the AI school. In addition, the newcomers and even some of the regular Shiokai people had to turn to the administrator to find a way out of the library, otherwise many would probably starve to death......

Looking at the three-dimensional passage in front of her, Xiaoxi slowly slid down a slide-like passage, it was not a pleasant experience to slide down in such uneven places, and even the lighting was all thanks to the tiny devices that flickered and flew around like elves, which were also Miss Baixi's monitors and microphones.

She couldn't help but think of a popular urban legend some time ago, which was said to be a terrifying story of the stumbling upon mysterious bones in the passages of the Holy City Library, which had been piled up into a dead end. Of course, anyone who really understands knows that Miss Hakumi, who can fully monitor the state of the library, could not let the reader die in this library for no apparent reason, and that incident turned out to be nothing more than a prank...... It's just a very realistic replica toy.

However, it did succeed in scaring the discoverers at the time......

After arriving at the string of flat areas crisscrossing below, Xiaoxi looked at the passage in front of her where the terrain had become completely different from the last time she arrived, and smiled helplessly: "Miss Bai Xi, please help guide the direction, what you should know is the place before." ”

"Sure enough, are you going there this time?" A glittering miniature device floats by...... Miss Bai Yu's smiling voice came from the things that are sometimes nicknamed the spirit of the library, and the wall of the originally completely closed passage on the right side in front of her suddenly cracked slowly enough for people to pass through, from which it can be seen that the change in the terrain of the library is definitely due to her, and there are obviously many gearing devices hidden behind the passage composed of books here that can automatically change positions, "Permission has been unlocked, please follow the guide line." ”

Although it is theoretically casual, if you are given a clear goal, you can still get directions, whether it is a special place you have visited, a specific book, or someone who has asked Miss Bai Xi before...... Exit the direction of the exit of this maze of books.

Although the place she was going to was a bit special and would not easily change its location, Xiaoxi was obviously not interested in finding a new path in this labyrinth of terrain changes, but directly used the function of finding historical places, and the walls and ground were shaking along the way.

Eventually, a slender guide line raised from the ground led her to the end of a passage, where the books that made up the floor parted to the sides, revealing the smooth stone slabs below...... The components of this maze of books are all books that can be taken down, which means that as long as you have the patience to slowly take out the books that make up the passage, you can pass through the walls, but if you ask Miss Bai Yu to help find the way, she can make the books that stand in the way automatically move out of the way. Unlike the rest of the world, the floor is made entirely of stone slabs, which normally represent an impassable boundary in the library area, but the stone slab in front of it is filled with strange ancient characters and regular grooves.

Xiaoxi stood at the edge of the stone slab, looking at the ancient words carved above...... It is said to have been written thousands of years ago when the first holy city was founded. However, the so-called language and writing are nothing more than tools invented to facilitate people's lives, and they will inevitably be affected by the times and produce a series of changes, so the writing used by the people of Xihai today has already undergone earth-shaking changes from the words that were originally taught, and this kind of writing called ancient Chinese characters has also become a ghost in the eyes of many Xihai people.

However, she knew these characters, and because she had to study them, after studying some ancient Chinese materials in the library, Xiaoxi could already read the ancient Chinese characters carved on this stone tablet very fluently, which was a poem that seemed to have a special meaning.

"The first god sounded the ancient trumpet outside the Nine Heavens,"

"The second god came from afar in the bright starlight,"

……

"The thirty-seventh god stood in front of Tian Yuan and stared for a long time, turning the entire starry sky into a phantom with a wave of his hand......" Xiaoxi slowly finished reading this passage that had been read many times, and just after her last sentence fell, the stone slab in front of her slowly moved to the side, revealing a slender staircase leading to the bottom, "What do these words mean?" ”

Looking at the slender stone staircase passage, Xiaoxi seemed to remember the mysterious appearance of Teacher Shanfeng when she first came here, and she couldn't read these ancient Chinese characters at that time.

"No, teacher, do you really know what kind of secret room there is?"

"It's a secret that can't be easily revealed." At that time, Teacher Shanfeng was obviously very satisfied with Xiaoxi's shocked appearance, "It's up to you to learn ancient Chinese characters well, otherwise even if you remember the password to open the door here, you won't be able to get any valuable gains from here." ”

She slowly stepped into the slender stone staircase, the stone slab that served as the entrance slowly closed behind her, and the low vibration outside indicated that the books that had been removed were slowly moving back into place. If it weren't for the guidance of Teacher Sugi, she probably would never have discovered this special secret room, after all, she needed to dig exactly to the bottom of the maze of the sea of books, and be familiar with the ancient Chinese characters, and be able to accurately read the words depicted on this stone tablet here.

This kind of coincidence, I'm afraid that in thousands of years, few people have been able to completely rely on themselves to discover this secret room, and this is not in the area where the Holy City Library can be directly searched, Miss Bai Xi will not directly take people to a place that they have not been to and do not know at all.

The lighting fixtures that floated in the sea also flew with her to this hidden space underground, illuminating it as brightly as the light of an artificial sun...... It's easy to tell it's different from the rest of the library, because there's something like a bookshelf there. Presumably because the books here are not as large as the maze of books above, far from fully constituting the walls, floors and ceilings, and in this seemingly spacious and bright room, only a few wide bookshelves can be seen in the middle, on which are stacked some books made in the same uniform sealed box as outside. It's a place where very few people come, at least so far, Xiaoxi has only seen her and Teacher Shanfeng come to this place, so she doesn't even need to worry about books being messed up.

Of course, it is easy to see that this place is still under the purview of Miss Bai Xi, but compared to the books in the outside world that have changed their characters with the development of the times, the books here are completely printed in ancient Chinese, and there are no annotations or translations in them, which is one of the reasons why Xiaoxi had to learn those ancient Chinese that she can barely use on her own. She now had a vague realization that this was definitely more than a simple library room, and that the contents of those books were more like fiction stories than popular science books, but those seemingly unfounded stories were too real to be easily denied, even if they were so shocking.

She stepped out of the stone staircase and stepped on the floor of what appeared to be made of white rock, which seemed to be the same material as the library, gently stroking the books that looked exactly the same on the shelves in front of her. The books are very old, and the boxes that were completely sealed on the surface have shown signs of corrosion, but the names of the books that have been sprayed with special paint on the sides of the boxes are still clearly recognizable.

These books seem to have been left a long time ago, and even the names are very similar in format: "Heavenly Dream - The Origin of the Creation of the Star", "Memories - Penglai of the Night", "Dawn - Prayer for the Moon for a Thousand Years", "Star Sea - Notes on the Abyss", ......

And what these ancient books have in common...... Author: Xinglan.
