"Alright, I won't tease you anymore."

Deng chuckled and shook her head.

"I know what you want to ask about, it's nothing other than the matter of the 'Calamity Demon', right?"

Although Deng's tone always gives a slightly irritating feeling, there is no denying her strong ability to read people. Yun You had no way to refute it and could only nod gently.

"What exactly is this Calamity Demon? Why do Zhao Xuan and the others think that just by seeing my eyes, I must be that Calamity Demon..."

Listening to the girl's question, Deng grinned.

"The Calamity Demon... well, as the name suggests, it's a demon that brings calamity."

"Red eyes are the hallmark of the Calamity Demon; normal people do not have such colored eyes, so of course they can recognize your identity at a glance."

"As for where the Calamity Demon actually came from or what it signifies, well..."

Deng paused slightly, then blinked and showed a cute but somewhat provoking expression.

"I'm sorry, I have an agreement with someone not to directly disclose the ins and outs of this matter to others."

"However, your master, Jin, should know something, just like Zhao Xuan, so you could ask him, and maybe you'll get an answer."

"And even if you end up getting no answer, it doesn't matter because one day you will understand everything."

Yet another puzzle master.

Even though Yun You was mentally prepared for Deng not to speak normally, she couldn't help but feel disappointed when Deng indeed didn't.

"Alright then..."

She shook her head, then waved the book in her hand, asking, "And what's the deal with this book? How can a few strokes from you turn an ordinary book into something capable of taking down a Quasi-God Strong Person?"

"Ordinary book?"

Hearing this, Deng grinned and shook her head.

"You misunderstood; this is by no means a regular book. In the Cosmic Library, there has never been anything ordinary."

She took the book, pointed to the sparse words on it, and explained, "What I'm about to say might sound unbelievable. You can take it as truth or merely a joke~"

"Firstly, every word in this book doesn't just record the life of that guy Zhao Xuan, but rather countless independent... infinitely vast universes existing in another dimension."

"The rules of this universe world are completely consistent with reality, and its scale is identical. You can think of it as parallel worlds. However, these worlds exist because of Zhao Xuan's fate, centering around him."

"You may have heard that every decision in a person's life holds infinite possibilities. This is no exaggeration, but a fact."

"For instance, when you first sought revenge and faced the decision of how to kill Yang Lie, you created countless possibilities. And each possibility, from a more objective perspective, creates a real existing parallel universe. A collection of countless parallel universes forms... a word in this book."

Deng pointed to the first word on the page, and Yun You looked carefully. At first glance, the word seemed beautiful, with clear strokes.

But the more attentively she looked, the more strokes she discovered, unable to count them—it was indeed infinite.

Yun You had no idea how Deng managed it; it seemed like something out of a fairy tale to her—an infinite-stroke word, how could it possibly be written?

Yet Deng did it, and seemingly without difficulty.

"Actually, a page in the book often contains infinite words."

Deng continued to explain, "Because on a microscopic level, a person can create countless possibilities every moment, even the smallest change spawns infinite possibilities."

"And this thing called time is actually without a lower limit. Some people believe the smallest time in the universe is 'Planck time', or 10 to the negative 43 seconds, but this is merely the smallest time humans can detect; it essentially divides infinitely down."

"Therefore, a page in this book represents the number of parallel universes generated by a phase of his life's changes."

"Now, Little Youyou, go ahead and flip through the book."

Deng handed the book back.

Yun You took the book, lightly flipped through a few pages as instructed.

Soon, she discovered that the seemingly around hundred-page book was essentially unending when flipped through.

Its number of pages also exhibited an 'infinite' status.

"This book is the parallel worlds a person has created throughout their life."

"And then..."

Deng gently waved her hand, causing the bookshelves around Yun You to gradually part, unveiling the vast, star-like infinity of books.

"The book I gave you is just a version written in one language. In reality, the same book exists in infinite versions written in infinite languages. Moreover, with each smallest unit of time, these books claim an infinite number of entirely different era editions, which also contain the aforementioned... real existing infinite universe worlds."

"All these books combined represent everything about Zhao Xuan here in the Cosmic Library."

"And the words I wrote in that blank book were to give Zhao Xuan an 'ending', stripping him of all possibilities. In defeating him, I also destroyed all the books he created and those parallel universes, drawing a complete 'full stop' for him."

"Well, that's the gist of it."

After saying this, Deng licked her lollipop, sporting a playful, innocent little girl demeanor, totally unlike the super strong being who just with a flick of her hand destroyed a Quasi-God and parallel universes.

Regarding the string of concepts Deng mentioned, Yun You was left utterly perplexed, not quite comprehending.

After all, she hadn't received much education, so her understanding of parallel universes and infinity stayed only at the level of some common sense and media depictions.

But she sensed that Deng was undoubtedly powerful, unbelievably powerful—capable of destroying universes with ease.

Such strength, in the real world, she couldn't even imagine how formidable it would be.

However, Deng seemed to have her own concerns, so she didn't interfere much with the real world.

Moreover, apart from Deng herself, this Cosmic Library was quite extraordinary.

Yun You turned her head, looking at the bookshelf beside her.

Like the book itself, a single bookshelf's collection appeared inexhaustible, never-ending, despite showing just a few dozen books on the surface. In essence, it probably held 'infinite' books.

Noticing that the bookshelf was constantly changing, growing, spawning more new books moment by moment.

And such bookshelves, every layer within the library had infinite ones, while the library itself possessed infinite paths and infinite spiral staircases leading to infinite directions.

In summary, the library took the concept of 'infinity' to its extreme.

"Quite something, isn't it?"

Deng smiled, speaking softly, "The essence of the Cosmic Library is the root of the worlds, the ultimate mystery that most Death Gods of the past sought. Whoever controls this place has the opportunity to control everything."

"It's a pity though..."

Saying this, Deng's voice suddenly became a bit low.

"Even grasping it, there remain mysteries in this world beyond our comprehension. Perhaps this is what they say, 'knowledge is ignorance'. "

Deng once again became a puzzle master.

Yun You sighed helplessly, already used to Deng spouting things she couldn't understand.

"So, is there a book of mine here?"

Yun You glanced around for a moment, then casually asked, "If there is, can it change my destiny?"

"..."

Hearing this, Deng, lost in self-indulgence, suddenly fell silent.

She stared straight at Yun You, a strange gleam flashing in her eyes.

"You know, Little Youyou."

"Normally, everyone in the world has their own book in the Cosmic Library."

"But..."

"The Calamity Demon, however, is an exception."

"Here, there are no books about the Calamity Demon. Your destinies always float beyond... the observable range."
