According to what Guangta said.

There is a wall built in opposite substances between each area, which is used to isolate the special effect of taboo knowledge.

The so-called "transcendent material" is the ropes Anle has always cared about, the materials contained in the walls and the ground.

However, they are not actually made of 100% transcendental matter, but are just a little mixed in.

This seems to be a valuable and expensive material.

Even if the Guard Department is rich and powerful, you cannot squander it at will.

On each wall, there is a door for passage.

Hearing this, Anle couldn't help asking, "Who will manage the switches of these doors?"

"Without any restrictions, wouldn't anyone have access to the most dangerous areas?"

Guangtai was not surprised by this question at all: "You will know soon."

The first door of the library is not far away.

The gate is more than three meters high, as tall as the walls, connecting the ceiling and the ground together.

When I walked in, Anle realized that this door was more like a mirror than it was called a "door".

It looks very rough on the surface, but they clearly reflect their appearance. The corners of the mouths of the people in the mirror seem to have a strange smile.

"Don't think about anything, just walk in."

Guangtai took the lead in taking action, took steps, and his body passed through the door without any stagnation.

In just a few seconds, it disappeared.

Only ripples like water waves were left on the door.

Anle walked in as he did.

When the toes first touched the door, a strange touch was transmitted to the peaceful nerves through the shoes, and a slight throbbing began to spread.

A bit like... going through security check?

This mirror-shaped, but unreal-touchable substance is scanning his body and soul.

Before Anle could think too much, he had already passed through the mirror and arrived at the other side of the door.

‘Huh? It seems nothing is wrong.’

Anle looked back and saw the ripples on the mirror slowly dissipating and soon returned to peace, as if nothing had happened, dispelling his doubts.

But the two didn't know.

At this moment, the other side of the mirror suddenly trembled violently.

The originally quiet water waves were like waves rolled up by typhoons, manic and violent.

This restlessness lasted for a long time before slowly calming down in the darkness.

And in front of Anle at this moment, there are rows of neat bookshelf.

Similar to previous feelings.

Even though the light was on above my head, the light was particularly dim, and the corners seemed even darker, and the strange aura spreaded silently.

It seems that the books on the bookshelf are quietly swallowing the light.

An idea emerged for no reason in peace—

‘This library is like a... prison?’

A prison where taboo knowledge is imprisoned!

At the same time, the feeling of desire in Anle's mind became stronger and stronger, and the flame in his brain burned even more vigorously, driving him to read and absorb.

Guangtai didn't notice Anle's abnormal mood, pointed to the door that looked like a mirror and explained to Anle.

"This is an extraordinary relic - the "Mysterious Door Mirror", which is one of the most friendly extraordinary relics."

"Not only have I never heard of its record of hurting people, it can also automatically supervise this library to prevent people with insufficient strength from entering...it seems to be its own requirement."

Resisting the desire to rush forward to study, Anle listened to Guangta's explanation silently.

He raised his eyebrows.

During this period, Anle also gained a certain understanding of the extraordinary relics.

If you really want to say something, a small pure white sculpture can be regarded as an extraordinary relic.

He thought to himself: "No wonder no one needs to manage it internally, it turns out that there are such extraordinary relics."

‘What is this? Good self-management ability?’

Guang Tai paused and continued, "I don't know very well. What exactly is its judgment principle? It seems to be related to mental tolerance? It refuses to let you in, indicating that you cannot bear deeper taboo knowledge."

His expression suddenly became serious, warning Anle.

"However, don't take its judging criteria as truth. It is extremely dangerous to rashly penetrate into the C or B areas."

"On the periphery, people still gain knowledge."

"But when you get to the depths... it turns into knowledge cannibalism."

Anle nodded, suppressing the heat of restlessness and thinking: "You say less, I'm about to...can't help it!"

"Call me if you encounter any emergency."

Guangta finally finished the explanation, waved his hand and walked towards the dark bookshelf.

The back gradually disappeared into the dim light and was no longer visible.

Seeing this, Anle showed the old farmer's simple smile when the harvest was about to be harvested and walked straight to the deeper area.

‘Honest it, bear it again.’

He finally came here for a while, so he naturally had to try his best to maximize his interests.

Although the outermost e-level area is also very attractive, it is definitely the internal taboo knowledge that can be exchanged for more filthy and rationality.

It is also very important to learn to be patient.

After a while, Anle walked to the end of the e-level area.

It is also a "mysterious door mirror", but it is slightly different from the moment.

When Anle walked to it, the figure reflected from the mirror was no longer himself, but a completely strange man.

He was wearing an old-style windbreaker, a bit like a medieval detective or gentleman.

His face and figure were blurred, as if hidden in a shadow.

Anle guessed: ‘Does the mirrors look different from each mirror?’

At this time, the man in the mirror took off his hat and made a standard and gentlemanly hat-taking ceremony, and disappeared behind him.

‘He is saluting me?’

Anle became more and more surprised.

But he didn't give too much explanation around him, and he didn't have time to study this problem at this moment, so he soon stopped thinking about it.

After passing through the door mirror, Anle is looking for suitable targets in the D-level area.

In fact, it is not a bad idea to directly enter the C-level area, but Anle is still very cautious. First try whether you can accept D-level knowledge, and then explore in depth to make it safer.

The surroundings are even deeper than before.

The lights are sucked away by something, just like an invisible black hole in the air.

Anle looked at things a few meters away, and they were all swept by darkness and could not see clearly.

And in the shadow of darkness, there seems to be something always watching happiness?

‘Is it taboo knowledge?’

They are active beings, and it is normal for them to act like this, just like small animals in the forest, they will be curious about humans who have mistakenly entered it.

Anle thought, and the smile on her face became brighter and brighter.

‘It’s exactly what I want.’

His mind was as hot as a soldering iron. He had reached the extreme of patience and was time to release it.

Anle strode towards the bookshelf and murmured softly.
