Li Cheng Yi and the other two entered through the gap on the side of Zhou Lu and the others. As they passed, Zhou Lu suddenly paused slightly, his eyes glancing sideways at Li Cheng Yi.

He seemed to have sensed something, but it wasn't clear. At his current level, he could step into the Holy position and become a Saint at any time.

A Saint is indestructible, eternally unique. After self-containment, they achieve a position that transcends cause and effect. As long as they are within the blind spot of their sanctification, they are invincible.

This realm is actually equivalent to minor omniscience, so it was normal for him to be able to sense the subtle differences in Li Cheng Yi.

"What's wrong, Senior Brother Zhou? Could it be that you've felt something and gained some insight?" A tall junior sister with purple flower ornaments in her hair said softly.

"Nothing, let's continue our previous topic." Zhou Lu said blandly, "Regarding the type classification of stress responses in basal cells, I divide them into seventeen major categories and sixty-five minor categories..."

The group began to discuss earnestly again, their voices undisguised, making Li Cheng Yi, who was passing by in front, feel a headache coming on.

"Let's go, let's go inside first." Chun Fan pulled him from the front.

The two followed behind Que Ru, who was at the very front, and entered the library together.

As soon as he entered, Li Cheng Yi's pupils contracted slightly.

The entire library was no different from ordinary ones in terms of layout, but the key was the books on the shelves.

"By the way, you should know the taboos of Yao Garden, right? If you do, please remind them for me." The black-skirted woman said softly.

Chun Fan also patted Li Cheng Yi, signaling him to follow suit.

"Yes, thank you for the reminder, Senior." Que Ru was the first to lower her head and thank her.

Both of them placed their waist tokens on it.

There were sparse people inside the library, but most of them were looking for books, not reading them.

Looking at Que Ru, a hint of nostalgia flashed in her eyes.

Li Cheng Yi was surprised to find that his waist token had somehow returned to its original state. The cracks on it had automatically disappeared long ago.

This library seemed completely different from what he had imagined.

Inside the library, a beautiful woman with a semi-transparent figure and a long gray-black dress was quietly holding a book, sitting behind the counter to the right of the entrance, flipping through it.

"Do not touch books that are degenerating and becoming transparent. This represents that the system within is being questioned, resulting in system collapse, and they may become false books. Once you absorb knowledge from false books, it will cause huge cognitive distortions."

"Work hard. Your mother and I were best friends back then, but unfortunately, she lost sight of the bigger picture and missed a great opportunity, stopping short of becoming a Saint..." the black-skirted woman said in peace.

"Yes." Que Ru bowed again.

After bowing earnestly, she led Chun Fan and Li Cheng Yi towards the aisle inside the library.

Que Ru walked to the counter and gently pushed forward her Ziyun Pei (Purple Cloud Pendant) waist token.

The other two followed suit.

Leaving aside the covers of these books, the main point was that some of their physical forms were semi-transparent, looming in and out of sight. Some were slowly burning, charred halfway through.

Still others were covered in mold, looking yellow and green, quite disgusting.

Even more books had small mushrooms growing on their covers, colorful, with tiny insects flying around.

The woman in the gray-black dress raised her head, revealing a pure face that somewhat resembled an Eastern European. Her dark eyes swept over the three of them.

"Yes." Que Ru nodded again.

Li Cheng Yi carefully observed and found that many people took books and walked directly towards the deepest part of the library.

Obviously, there was a place to read there.

The three of them walked along the aisle. The gloomy library hall was wide and deserted.

The temperature was very low and very dry. Because everyone was communicating through sound transmission, there was no sound, so if you didn't see it directly, you couldn't tell how many people were actually here.

Several times, they encountered several people looking for books around a corner, and Li Cheng Yi couldn't even detect them.

It was deserted because this hall was the size of an entire football field, and the ceiling was hundreds of meters high, and the walls were densely covered with bookshelves.

Countless books were stacked layer upon layer, constantly moving forward and backward silently and slowly.

Those moving backward were becoming more and more transparent, while those moving forward were the opposite, becoming more and more solid, and might even emit light.

The further they went, the clearer these changes became.

Countless books on the bookshelves on both sides were constantly moving in and out, some appearing and some disappearing completely.

The alternation of old and new, the renewal of all things, this scene inexplicably aroused a trace of emotion in Li Cheng Yi's heart.

"Okay, you can freely find books here. All the prerequisite knowledge information needed for forbidden knowledge can be found here. You can freely search for the books you want to read. You all know the steps required for Divine Fire, so make up for what you lack.

I would also like to mention that there is an auxiliary learning secret realm here called Yao Garden. It is a special blind spot containing the Dao of Cataclysm, and the flow of time is extremely fast. Be sure to be careful when you enter, lest your own flaws be magnified." Que Ru reminded.

"Thank you for the reminder." Chun Fan was obviously prepared. After saying hello to Li Cheng Yi, he went to find the books he wanted to read.

Li Cheng Yi was a little confused and continued to ask Que Ru.

"May I ask, Senior Sister, what is this Yao Garden?"

"To put it simply, it's a time-accelerating secret realm." Que Ru had already learned about Li Cheng Yi's background and was not surprised by his ignorance, but explained patiently.

"Specifically, Yao Garden is equivalent to an extremely violent time-accelerating secret realm. The time adjustment within can be determined by you, no matter how long or how fast. But because of this, it has great dangers."

"You mean, the time flow rate is adjusted too quickly?" Li Cheng Yi frowned.

"Yes, someone once adjusted the time to one second inside and a million years outside in order to catch up on missing knowledge points urgently. And then..." Que Ru shook her head and didn't continue.

Li Cheng Yi felt a chill in his heart. This was truly hair-raising. What was the concept of a million years passing in one second? He was only a hundred years old in this life and his previous life combined.

"Now you understand, right? Don't be greedy when adjusting the flow rate." Que Ru shook her head. "We are cultivators of the Dao. What is the Dao? It is the path. The path is long and dangerous. Do not be arrogant or impatient. Only by advancing peacefully can you go further in the long run."

"Thank you for your guidance, Senior Sister." Li Cheng Yi sincerely cupped his fists and bowed.

"Go ahead. I hope we can meet again." Que Ru said lightly, then turned and left, soon disappearing among the other bookshelves.

Leaving Li Cheng Yi alone, standing in this wide hall with its dark and black main tone, looking at the constantly moving bookshelves, he felt somewhat at a loss.

He casually took out a black book on the left.

*Observing the Changes of All Things from the Perspective of Plant Life*, Author: Ausgaria Lieder (Golden City).

"Hmm..." Li Cheng Yi was a little surprised. He randomly pulled out a book and it turned out to be from the Golden City he had visited.

Putting it back, he walked forward a few steps and randomly pulled out another book.

*Evolutionary Theory*, Author: Huang Shanzi (Lian City).

He opened the book and flipped through it casually. It described the evolution of the sky.

He glanced at it and wasn't interested, so he continued forward.

According to the various knowledge systems he had absorbed in both lifetimes, the best thing for him to look for this time was basic scientific and technological knowledge of modern science and technology routes.

This would also save a lot of time on preliminary basic understanding.

Following the bookshelves, Li Cheng Yi quickly discovered related books in the technology category.

Without thinking twice, he searched for a pile and moved towards the direction everyone else was going, holding them in his arms.

Before long, at the deepest end of the library, a black circular door embedded in a space in the wall appeared before Li Cheng Yi.

Inside the circular door was a rotating, viscous black-purple liquid, and it was not known what material it was made of.

One reader after another was coming in and out of here.

No one spoke. Everyone quietly held their books, coming and going, without boasting or comparing. Most people's faces revealed a kind of rationality, indifference, and perseverance.

'That's right, those who can get to this point must be extremely persistent, heaven's proud children who have put in countless efforts and hardships.' Li Cheng Yi thought to himself.

Gathering his thoughts, he also walked to the circular door. Before he had completely approached, a message entered his mind.

'Do you want to adjust the time flow rate? (Please be careful of your own purification. If the flow rate is too fast, your own hidden dangers will also be magnified and become more serious.)'

Li Cheng Yi's heart tightened. He looked at the door in front of him, holding a pile of books, and stepped inside.

Hiss!

A flash of white light flashed before his eyes.

He entered a pure white, empty space with no furnishings.

The space was square, without even a table, completely empty.

A message entered his mind.

'Please select the flow rate ratio and state it verbally. The format is: Please adjust the time to a ratio of one to xxx.'

Li Cheng Yi thought for a while and slowly opened his mouth.

"Please adjust the time to a ratio of one to one hundred."

One hundred days here was equivalent to one day outside. He could accept this time flow rate.

'Adjustment successful. The current time speed of the space bookstore you are in is one hundred to one.'

After confirming this, Li Cheng Yi let go of the books in his hands, allowing them to float around him at will, and casually picked up a book about how basic particles construct metal-like material structures and began to read.

Although he had the Talented Flower Whisper talent, he hadn't used it yet, but the number of times he could use that Flower Whisper was limited, and it would be more cost-effective to save it for knowledge and experience that was not available in this place.

For knowledge that he could learn and absorb on his own, there was no need to waste such precious indicators.

Time passed little by little.

A large amount of knowledge began to rapidly integrate into his mind.

With his current consciousness strength and reaction speed, how fast was his knowledge absorption?

The powerful consciousness power blessed by the Thousand Faces Sword Sutra made Li Cheng Yi's memory and comprehension far surpass ordinary people.

He could finish reading a difficult work of hundreds of thousands of words in just a few minutes.

Under such terrifying efficiency, after ten minutes, he realized that he had taken too few books, so he left again to fetch new books from the outer hall.

He also checked whether the time flow rate adjustment was successful.

Just as Li Cheng Yi was earnestly studying hard in the forbidden library.

Deep in the Black Sea, Lian City.

Since some unknown time, because of the various unknown threats and dangers in the Black Sea.

Life groups have divided the known range they have explored into three positive and seven negative, a total of ten huge forces.

Although the known has continued to expand, become larger, and wider. As a result, these ten territories have become smaller and smaller than before, and their proportion in the known range has also become smaller and smaller.

But this division of three positive and seven negative is still used by all life groups.

Lian City is the headquarters of the All-Knowing Society.

This joint organization, which only powerful forces that have cultivated omniscient experts are qualified to join, represents the highest position of all life groups in the Black Sea.
