Under the vault of the Temple of Ravenclaw, in the finished library of the Temple.

The library is housed in a separate space similar to that of Responsive, and is seemingly composed of an indefinite number of equilateral triangular rooms, with each floor in the center of the room being hollowed out without ceilings and floors, and used as ventilation ducts, surrounded by low fences, from which one of the fences looks outward, upwards, to distant heights, down to the endless abyss, but it can be seen that each floor is divided into identical and identical rooms.

The problem of lighting is emitted by some crystal balls made of stars suspended in the air in the room, these celestial crystal balls are called according to the names of the celestial bodies that illuminate the sky, and move slowly in a certain trajectory in each triangle, the light they emit is continuous but does not sting the human eye, all the light is just right and comfortable, and can be adjusted to a certain extent according to the needs of the reader - In fact, these magical creations inspired by Arthur's Muggle smart lighting have become widespread in the Floating City, and the difficulty of creating and using them within the confines of the Cores is almost negligible compared to the traditional methods.

Each triangular room is filled with bookshelves on each wall, and each wall has a doorway in the center of the store, and the next triangular room is exited from any of them. Each floor has an infinite number of triangular rooms, and these are arranged like a beehive.

Nearly every façade of each triangular library was filled with bookshelves, and every now and then there were extra books on the shelves—the priests and wizards of the temple were replenishing the newly built library, marking them according to the various classifications of wizarding and Muggles, and placing them on the shelves on the walls, and the books would be immediately transported to the corresponding triangular room shelves.

Whether wizarding or Muggle, the Ravenclaw Temple was trying to collect as many publications as they could, and when a triangular room was full, new books would move on to the next, and there was even some hidden sinister staircase-like snack from the gods.

The catalogs of the library, and the contents of the fake catalogs, and the proofs of the fake catalogs, and the proof that they are fake, the proofs of the truth, and so on, are nominally designed to exercise the ingenuity of the readers who come to them—as if around every doorway in every library room, surrounded by the lenses of the Mirror of Eris, the mirror is unmistakably the most urgent and intense longing of your heart.

A creature that floats in the air with a Ravenclaw pendant around its neck, a cloak, and a whole body that looks like it has been soaked in water, has a scabbed palm, and its whole body is rotten like it— The Dementors, the Eris Dementors modified by Ravenclaw with a triangular mirror shard embedded in each of their palms, are patrolling up and down the ventilation ducts as guards and service personnel, and all the pleasure they use is drained of happiness wherever they pass and does not affect the library area outside the fence.

Readers can ask for the services of the Dementors who can create illusion symbols with their lenses, such as asking them for the only drinks and snacks available here to eat Coke and pudding, provided that you are clever enough to decipher and understand the logical meaning of the riddle-like symbols emitted by these creatures and communicate with them - although in reality the creatures can actually communicate directly with the English alphabet, their owners apparently forbid them to do so.

In addition, readers seeking this service should not be disgusted that your imported items will be touched by Dementors with crusted palms, and they will not answer the question of why the Ravenclaw Temple only serves these two foods, one of which is still a Muggle drink.

To enter any of the libraries, they must wear a Ravenclaw pendant, and prior to entering, they must obtain prior application and permission from the Temple Librarianship, and they can only view the categories of rooms that are open or allowed to enter, such as those that provide the temple in return and are allowed access to secret knowledge.

The reader wears a pendant to ensure that when they walk through the entrance opening, the triangular room they stay in is the one where they need the most knowledge, and the location of each room in this library is not fixed, as long as it takes a while, each room will teleport and change to another position, just like each piece of a puzzle can be swapped in the same way.

This is forbidden, and the apparition shifters and the teleportation methods of the elves or phoenixes cannot be directly teleported into it, and if you want to violently break through this defense mechanism, you will be immediately detected by the temple.

Intruders who want to use something like the Transfiguration Charm directly from the entrance, even if they are strong enough to evade the guards' defenses, will be trapped in a room in the Infinity Library waiting for the temple to be apprehended and punished by the temple for not wearing a licensed pendant and those readers who are trying to read the books that have not been licensed.

These violators will never find the right way out, and even if they are lucky enough to see the entrance, they will be crossing

The doorway is randomly teleported to another room - and the entire library is in the Ravenclaw Temple, and everything that happens here is in the hands of the Ravenclaw in the vault at the top of the temple.

Overall, the ever-expanding library of the Temple of Ravenclaw contains all possible books, whether it is future prophecies or past history, magical or non-magical, true or false knowledge, and so on - the theoretical upper limit of the number of books in this library is truly infinite, and it is the ultimate library containing infinite knowledge and all the books.

And now, on the edge of the fence of a triangular room in the Infinity Library, a well-dressed old man with pale skin and hair, and a well-dressed young wizard with pale skin and hair, who was lying on the fence and vomiting downward, patted his back to prevent him from choking on the carbonated drink and pudding mixture he vomited.

"Your library is a product of the gods, emphasizing the eternal existence of the library and giving it a sacred and mystical color... It is the general product of the infinite universe of infinity. The old man's frustrated voice began to be sarcastic, "But Alan... I didn't expect you, as a Quidditch star, to have motion sickness... Why do you have so many extravagant gimmicks... Ahh

The old man pulled Alan from vomiting on the fence, so that he would not be touched by the vomit that he had spit out and fell underneath and then appeared from the top of the top, and the Dementors were flying from the layers to the hollow in the middle, each picking up a trash can to try to catch the remaining vomit, many of which appeared to be drenched.

“... I just ate a little more... Sorry, Gatler... Let's go out and visit the university..."Although Alan was remarkable, he was embarrassed by the fact that he was embarrassed by the library he and his mother-in-law co-designed, and he wanted to get motion sickness, "This library still has a lot of room for improvement..."
