On the other side of the upside-down bookshelves, on the opposite side of this layer of invisible matter, there is another row of bookshelves that are contrary to the previous gravitational force, and if I want to say it, I want to compare this layer of invisible matter to a sphere, in which the shell and inner wall are placed exactly the same bookshelves, and further inside is a layer of invisible matter, and the inner wall and shell are also full of bookshelves.

In short, in this way, these bookshelves are lined up in rows in the innermost space, stretching inward for dozens of kilometers until they are closest to the center.

In the center, a pale green ball is floating silently.

Not far from the pale green sphere is a white platform of nearly 1,000 square meters, which is roughly in the shape of a disc, like a planet orbiting a star, slowly rotating around the pale green ball at a uniform speed.

As for the decoration and arrangement on the surface of this white platform, it is extremely simple.

A wooden table, a single sofa, a few books, and a wooden mug are pretty much everything on this white platform.

At this moment, a young man is sitting on this sofa.

He held an unknown book in his hand and seemed to be reading quietly, while beside him, a tall brown-haired woman stood respectfully.

"This is it. ”

After the oasis brought Mo Ren to the deepest layer, he also smiled and said to Mo Ren: "This is the library of Lord Answerer, and I still have some topics to finish, so please go over by yourself." ”

"Hmm. ”

Mo Ren nodded, there was nothing wrong with that.

"See you later, Your Excellency. After seeing Mo Ren nodding, the oasis side also turned around directly, and then left this incomparably huge library.

After the oasis left, Mo Ren looked at the spot for a moment, and after seeing that the answerer and the tall brown-haired woman did not move, they flew towards each other on their own, and the translucent material used to support the bookshelves did not stop Mo Ren, they looked like illusory images, Mo Ren easily passed through them, and flew towards the most central position layer by layer.

Although the entire library could almost be said to be unusually large, it was nothing to Mo Ren, so it could almost be said that in the blink of an eye, Mo Ren landed on the white platform.

And when Mo Ren's feet just stepped on the platform, he clearly felt the strange changes in the gravitational field, the white disc under his feet was like a planet with a real gravitational mechanism, so that when he looked up, it was as if it was not the platform rotating, but the platform was stationary, and the entire library began to slowly rotate.

"You came earlier than I expected. ”

When Mo Renzheng was looking around with some curiosity, the person who answered also put down the book in his hand and said to him lightly.

"There's probably a lot to do next, but there's still plenty of time to spare. ”

After hearing the words of the answerer, Mo Ren also shifted his attention to the other party, but although his attention was completely focused on the other party, Mo Ren still couldn't see the other party's true face as always, and could only vaguely feel that the other party was a young man, and he couldn't see anything else.

"Good. ”

The answerer nodded, handed the book to the brown-haired woman next to her, and asked, "So what do you want to know?"

"All of it. ”

Mo Ren replied.

"It's good to be inquisitive, but you shouldn't have enough time to learn about it all. ”

The answerer shook his head slowly, and then he didn't see any movement, and suddenly another sofa appeared on the other side of the wooden table: "Sit down first, you should have at least sixty-eight hours and thirty-two minutes to stay here, which is enough for me to tell you something important." ”

"Hmm. ”

Mo Ren nodded, and then sat directly on the sofa.

"I can tell you have a lot of confusion. ”

As soon as the answerer raised his hand, a book flew over from a bookshelf a few kilometers away, and then he handed the book to Mo Ren: "You can take a casual look at these books first, I think this should solve a doubt in your heart." ”

"Good. ”

Mo Ren took the book with mental power, and then directly put it in his hand and read it carefully.

This is not a book of exercises, nor is it a secret book, when Mo Ren turned the first page, the top of the table of contents reads' The Metal Smelting Manual of the Ancient Istanbulka Tribe', and when Mo Ren opened the second page, it was basically densely filled with all kinds of smelting techniques, and then all the contents were similar, such as the mining and sorting of ores, cleaning and screening, the ratio of soil for building the smelting furnace, the height of the flame, the method of charcoal firing, a lot of mess, and there were even a lot of fine illustrations.

It can be said that even a fool with unsound intelligence, as long as he can do the honest things recorded in this book, he can smelt the metal tools of the ancient Istankas tribe.

However, this smelting technique is not a very advanced thing, and it can even be said to be something completely meaningless to Mo Ren.

So, the focus of the book is clearly not the content.

“……”

Realizing this, Mo Ren flipped through the book from the beginning again, and began to turn his attention to something other than the content.

Soon, Mo Ren discovered the problem in this book.

"The book ......"

Mo Ren carefully pinched a page with two fingers, and his brows furrowed slightly: "The thickness of each page is completely equal, and the accuracy value even exceeds the molecular level, are you doing this on purpose?"

"It's just one characteristic. ”

The answerer didn't know where to take out the other two books and handed them to Mo Ren: "You look at these again." ”

"Hmm. ”

Mo Ren nodded, and then took the two books handed over by the answerer, found one casually and immediately flipped through it.

The name of the book is "DRP-9421 Plant Observation Record", but it does not contain many contents, only a few dozen pages, but the book is the same thickness as the "Handbook of Metal Smelting of the Ancient Istanka Tribe" that I saw before, but the number of pages has decreased, which means that none of the pages have changed in thickness, and these pages look like cardboard.

But the only thing that hasn't changed is the accuracy of the thickness of each page, and the thickness of each page is almost absolutely equal, at least at the molecular level.

Frowning slightly, Mo Ren turned his attention to another book.

After opening the other book, Mo Ren also habitually glanced at the title on the first page, which read: 'Partial Answers to the Future and Principles of Speculation - Written in 2000', which looked like a book of prophecy or something, but when Mo Ren used two fingers to turn the next page, a strange question appeared out of thin air.

Mo Ren smoothly turned to the next page, but the thickness of this page was almost impossible to observe by Mo Ren, and the remaining pages did not seem to be reduced even a little bit of thickness.

“？？？”

Seeing this strange phenomenon, a rare trace of doubt flashed in Mo Ren's eyes.

In the next second, the vast thought was activated in an instant, and the transformation effect was turned on to the maximum power, strength, range, and explosion in an instant, and almost all the attributes were transferred to the accuracy by Mo Ren, and considering that Mo Ren was already a little unbelievably strong, at this moment, after the transformation, Mo Ren's accuracy could even manipulate a single atom, and even separate the electrons from the nucleus.

But even though Mo Ren had raised the accuracy to the maximum, he could not correctly grasp the precise thickness of this page.

It's a bit against the laws of physics.

The thickness of this page is almost non-existent under Mo Ren's observation, Mo Ren randomly captured a hydrogen atom in the air, and compared it with the thickness of the page, it turned out that compared to this page, the entire hydrogen atom is like a huge and boundless planet, and even if this page is a little harder, it can be directly inserted into this hydrogen atom, splitting the whole atom in two.

“……”

To be reasonable, Mo Ren's brows furrowed almost immediately after seeing this scene.

How thick should each page be smaller than the diameter of a hydrogen atom?

If the pages of this book are made of paper, then the composition of the book should be wood fiber, that is to say, its main component should be lignin, and among the tiniest components of lignin are carbon atoms, hydrogen atoms are smaller than carbon atoms, theoretically speaking, if the book is really made of paper, then its thickness cannot be smaller than the diameter of hydrogen atoms.

Not to mention its own thickness, even if there is really a technology to make such thin pages, the van der Waals force between the molecules will be too thin to support itself, and eventually lead to complete cracking and damage.

But now the page, which looked like a piece of paper, was smaller than the smallest atom in terms of thickness, and showed no signs of shattering at all.

[Is this something that was created by some kind of ability?]

Mo Ren was still holding the page in his hand, and his heart was thinking quickly.

If it is a book made by a certain ability, then it is very simple that this book can violate the laws of physics, because the vast majority of the abilities of the external system and the rule system can themselves destroy the laws of physics, so whether the book is reduced in thickness because of the way the space is distorted, or the book itself is not made of particles, it at least makes sense.

Thinking of this, Mo Ren tried to look through the contents of the book again, and found that there were many detailed descriptions of the future direction, some of which were verified, and many more were not.

But because the thickness of this book is almost small to an unbelievable realm, the actual number of pages in this book is also very exaggerated, Mo Ren can only jump and turn the page, and even so, Mo Ren spent a long time to turn to the last page, and the future direction described on this last page is the future direction of mass extinction, some black insects that just look terrifying and inexplicable poured out of the shattered space, devouring all living beings in the entire world, and then the stars began to go out, and a low horn was blown as if announcing destruction, and everything finally fell into eternal coldness and silence.

“……”

After reading the book hastily, Mo Ren frowned slightly and fell into silence.

"Looks like you're already clear. ”

After seeing Mo Ren put down the book in his hand, the answerer also said to him: "What is stored here is not a paper book in the conventional sense, if I want to, the information that can be recorded in each book can reach an almost infinite level, so at least in a short period of time, it is impossible for you to grasp all this knowledge and information." ”

"That's what you're capable of?"

Mo Ren glanced at the answerer, as if he still didn't know the other party's true ability.

"Although I can use it too, it's her ability. ”

The answerer shook his head, and then introduced the tall brown-haired woman beside him: "The Chief Recorder of the Dark Green Courtyard, she has the ability to turn things into books. ”

"Hello. ”

The brown-haired woman, or the woman known as the recorder, also nodded slightly to Mo Ren when she was introduced.

"Hmm. ”

Mo Ren responded simply.

"Unlike the way the Negative Cult uses living beings as currency or the Crimson Holy See uses bloodlines as a transaction, the trading currency inside the Dark Green Courtyard is knowledge, so this is not only a library storehouse, but also a treasure trove of the Dark Green Courtyard. The answerer said calmly: "Actually, the answer you want is basically here." ”

As he spoke, a book flew directly into the hands of the answerer: "Whether it is the research results of the six major systems of the ability, or the relevant information about the thirteen demon gods, or the exploration progress report of the underground palace, everything you want to know is here." ”

"These are really the things I want. ”

Mo Ren nodded slowly, but quickly continued, "But that's not all. ”

"I know. The answerer nodded calmly, and then a black book wrapped in plants suddenly flew to him.

"You want to know what's behind the scenes, right?"
