I'm a monster in Demon King's Castle

Li Yue walked out of the library hall and transformed into the “Book Demon.”

Since he was going to the upper levels of the library, Li Yue had already planned to make further contact with Boodiborger in the guise of the Book Demon—the Book Demon would "supervise" the hall every green hour and blue hour.

The Miniminees had no idea where he went the rest of the time, and Li Yue could only guess that as one of the managers, the Book Demon would rest in the upper levels.

Finding the Book Demon's gait in the Demon Illustrated Handbook, Li Yue tried his best to imitate it, and finally mastered the method on the way from the lower level to the middle level—the Book Demon's way of moving was mainly by fanning pages.

The huge body appeared very clumsy, and the frequency and strength of the fanning determined how far a "step" could go.

Having adapted to the Book Demon's movements, Li Yue jumped to the middle level, and then was taken aback—teaching the Miniminees to make barbed wire below, teaching them swordsmanship and fighting, Li Yue had temporarily forgotten that the current situation in the middle level was so bloody.

The walls and floors of the corridor were covered with cracks, some caused by Finley's wolf claws, and some caused by Li Yue's bone river; following the scattered bones on the ground, there was a large pool of blood at the entrance of the eleventh library room, which was now covered with a layer of gray haze, but still grinned ferociously on the ground.

The front of the Gate of Chaos was even more shocking.

The walls, ravaged by the scorching magma and the Wild Hunt's bone river, no longer had their original solemn appearance, only a sword mark on the ceiling remained deep…

Ke'er was cut in half by Li Yue here.

After a little sensing, Li Yue knew that Bosh shouldn't have been here since Ke Li and Ke'er died, otherwise it would be impossible not to search the library for Scolerick…

When the blue hour comes, what new power will this guy bring?

Thinking, Li Yue collected the bones of self-healing along the way to clean up the scene, deliberately creating a false impression—in this way, whether it was Bosh or Boodiborger, it would be difficult to judge whether Scolerick was dead or not.

The road from the middle level to the upper level of the library was very quiet.

When Li Yue climbed up the stairs and stepped on the steps of the second floor, he suddenly sensed that the magic power contained in the air here was extremely strong, which was obviously Boodiborger's doing.

This also confirmed that the Book Demon would rest in the upper level of the library during the red hour—as the only high-level demon in the library other than Boodiborger, the Book Demon must have been nourished by magic power on weekdays, so it could only be the upper level.

This was a very simple deduction.

"Tsk tsk… If these magic powers were distributed to the Brain Spirits and Miniminees, perhaps more high-level demons would appear in the library."

Thinking this way, Li Yue finally jumped over the last step and came to an iron gate.

In a certain version of "A Brief Introduction to the Demon King's City Tour," the library was introduced as a whole—the origin of the library was similar to Li Yue's guess.

It was originally a library of a certain magical civilization before the Kalis Era, and was forcibly brought back to the Demon King's City during a raid by the Demon Expeditionary Force and embedded into the Demon King's City.

In the original structure, the top floor of the library was the forbidden book area, displaying a considerable amount of magical knowledge; however, after thousands of years, many books had been broken to pieces, and more had been scattered everywhere.

At this moment, the iron gate on the top floor was tightly closed, and did not automatically open because of Li Yue's arrival; many magical inscriptions with unclear meanings were carved on the iron gate, and Li Yue only slightly touched it with his mind, and felt that a lot of messy thoughts were stuffed into his consciousness, and hurriedly moved his mind away.

Next to the iron gate was a huge oil painting, which seemed to be a scene of a group of scholars entering the library—the scholars were painted vividly, with longing for knowledge, bowing their heads and entering.

However, upon closer inspection, Li Yue was startled by some details—some scholars had special postures, their robes drooping in a very irregular outline, with a small section of tail tip exposed at the hem of the robe, which was obviously not human; some scholars had goat horns hidden in their hair, which looked no different from ordinary people at first glance, and could only be seen upon closer inspection.

The scholars in the oil painting seemed to sense Li Yue's mental power, and glanced at Li Yue, causing Li Yue's scalp to tighten, fearing that the scholars in the painting were related to some inexplicable existence.

He was here to check Boodiborger's condition in order to judge the possibility of assassination, and Li Yue certainly didn't want to cause any trouble.

And probing Boodiborger's situation was something Li Yue had to do—killing Finley and Ke Li and Ke'er had caused such a big commotion, killing Bosh would inevitably be more intense, so this trip either completely solved Boodiborger's gaze, or he needed to ensure that he would not be disturbed by him before the blue hour.

Fortunately, the scholars didn't suspect anything when they saw it was the Book Demon, and opened a gap in the iron gate for Li Yue to enter and exit.

"Book? Why… why are you back?" Boodiborger's familiar thought came, and Li Yue knew he had been discovered immediately.

However, this was not beyond Li Yue's expectations—Boodiborger was healing and was fully alert to Scolerick.

With Li Yue's current ability, apart from directly using the blessing of "Stealth," there was almost no way not to be discovered by him.

"Something happened…" Li Yue jumped into the crack in the door, and then displayed a line of words on the page, "Scolerick fought with the trainees in the closed combat training in the middle level, three trainees died, and Scolerick disappeared."

The handwriting on the page was rigid and serious, no different from the font commonly used by the Book Demon.

This was also the confidence that Li Yue dared to impersonate the Book Demon to contact Boodiborger—the Book Demon's communication was not in the form of sound or thought, but in the form of text, so as long as the handwriting was imitated closely enough, Boodiborger would hardly notice the difference in the identity of the visitor.

And jumping into the iron gate, Li Yue almost thought he had gone to the wrong place—the terrain here was extremely close to the middle level of the library, except that the seventh library room was replaced by the thirteenth library room, and the numbering seemed illogical.

Along the corridor, first was the thirteenth library room, and then the eighth library room, the ninth library room… until the seventh library room at the end.

Moreover, the thirteenth library room was not a bone gate, nor was it so hideous, and it was no different from other library rooms.

This is… the former library?

Or… is it the library in Boodiborger's impression, the library in his imagination?

Are these all his imaginings?

Li Yue wondered to himself.

The only thing that was more conspicuous was the huge table abruptly placed at the entrance of the thirteenth library room—the table took up about half of the corridor, inexplicably matching Li Yue's current width; the desk was slightly tilted, and the bottom was lined with a horizontal bar, which was just enough to accommodate the Book Demon.

Li Yue suspected that the Book Demon rested here during the red hour, just like the famous rare books displayed at the entrance of the library, but it was quite simple, so simple that it was a bit hasty.

At this moment, a mass of mud was spreading outward from the door of the seventh library room, until the mud solidified into a head, Bode Collie's head.

Boodiborger appeared.

Compared to the last time they met, Bode Collie's facial features were more distinct, and the originally sunken cheeks had completely healed.

At this moment, he was lifelike, but his expression was still a little dull—it seemed that although he had not absorbed today's Brain Spirit, the Lord of the Brain Spirit was still continuing to recover his energy.

"Scolerick… Demon Wolf… What exactly is happening in the closed combat training…" Bode Collie slowly opened his mouth, "Do the Miniminees… know?"

Li Yue couldn't help but want to laugh, but he couldn't post emoticons on the page—Boodiborger really asked the right person, no demon knew more about the closed combat training than himself.

"Scolerick had a conflict with the pure-blooded demon Bosh in the combat training.

There may be some restrictions in the combat training that caused the pure-blooded demon Miniminees to attack, and the Miniminees suffered heavy losses…" Li Yue started with the truth first, and then gradually guided Boodiborger's thoughts.

"The conflict spread to the middle level of the library, affecting the Brain Spirits, and all of today's Brain Spirits died…" Li Yue lied, first ensuring that Boodiborger would no longer attempt to absorb the Brain Spirits, solving the biggest threat.

As for the abnormal wolf howling that occurred in the Forbidden Forest, Li Yue did not mention it.

"Lord Boodiborger… How is your condition?" Li Yue didn't dare to ask too directly, but hoped that Boodiborger could talk about some of his situation and recent itinerary.

However, it was not Boodiborger, nor Bode Collie, who answered Li Yue's question.

"Are you asking me… I'm fine… and not fine…" The voice of an old human suddenly sounded behind Li Yue, startling Li Yue's brain.

Who is it?

Why is there no perception?
