I'm a monster in Demon King's Castle

“What… what happened…” Finally, Budiboge's voice echoed in Li Yue's mind.

Following that, Li Yue saw the grand staircase leading to the upper level of the library instantly enveloped in shadow, obliterating the moonlight and candlelight.

“Skor… Rick…? ” The voice in his mind continued, accompanied by a wave of pressure. Li Yue saw an irregular, blob-like object appear on the grand staircase, slowly moving towards the entrance of the thirteenth archive room.

When the blob-like object was illuminated by the moonlight and eerie white bones, Li Yue finally saw the full appearance of Budiboge—a dark brown brain spirit embraced and enveloped by layers of corpses and skeletons.

The corpses and skeletons seemed to retain consciousness and emotion. As Budiboge questioned, they squeezed out expressions of pain and confusion, all opening their mouths to inquire, causing the sound of doubt to reverberate throughout the middle level of the library.

“Skorrick… what… Rick… what happened… what are you doing… doing… the Gate of Chaos hasn't opened yet… you shouldn't be here… here…” The voices overlapped, mournful, filled with infinite resentment.

Li Yue noticed that the corpses embracing Budiboge were not only human, but also included magic wolves, lesser demons, and even female demons, all appearing in turn from Budiboge's main body, as if their wills had been unified.

“What’s… it to you? Huh? Budiboge?” Li Yue dispelled the fear in his mind, stabilized his emotions with the greatest willpower, and chuckled, “I came here to wait… for the opening of the Gate of Chaos. Do you have any questions?”

Budiboge did not answer, which made Li Yue feel very flustered—this Lord of the Brain Spirits must have sensed the tremors that had occurred here, so he came to investigate in person.

Fortunately, Skolrick's shattered bones had lost their light, revealing not too many traces of his past existence, and the bone sword was in Li Yue's hands, with the "Summon" button in Li Yue's mind.

“I just… had a nightmare.” Li Yue tried his best to perform Skolrick's arrogance and unruliness, “This lousy place of yours… really should be renovated properly…”

“A nightmare…?” Budiboge's voice echoed in Li Yue's mind again, “Do… skeletons also dream?”

What's going on? Li Yue really didn't know if skeleton soldiers could dream.

“Don't use your humble thoughts to pollute my brain anymore…”

Li Yue imitated Skolrick's tone, impatiently interrupting Budiboge, confronting him sharply.

Budiboge was silent for a moment, driving the corpses around his body, murmuring in unison: “My humble thoughts…?”

【Malice +382】

“Are… you… really… Skolrick? …?” The uneven voice completely surrounded Li Yue.

“What? Is it that you think my entourage isn't big enough? Want to arrange more servants for me? Or do you want me to call out the Skeleton King to have a good talk with you?” Seeing that the other party was suspicious, Li Yue had to bring out Skolrick's backing.

Although Li Yue didn't even know the Skeleton King's name.

After mentioning half of it, Li Yue was still a little afraid that it wasn't enough, so he exhausted all his known resources to put pressure on Budiboge, adding: “Or when you go to the arena tomorrow night, I'll find the Skeleton King to meet you?”

【Malice +463】

“Hmm…” Budiboge was obviously hesitant, but the amount of malice made Li Yue feel that it had no intention of attacking—he could still act.

At the same time, Li Yue also concentrated his mind, trying to use the Demon Illustrated Handbook to analyze Budiboge's mentality.

【Analyzing… 2%…】

Unexpectedly, even though Li Yue had included the Brain Spirit in the Demon Illustrated Handbook, he did not get Budiboge's information immediately. Obviously, this Lord of the Brain Spirits had transcended the scope of Brain Spirits and had its own unique "Name."

“Your aura… is somewhat chaotic…” Budiboge only said half of his words, also not sure of Li Yue's situation.

Li Yue knew the reason for the chaotic aura… Perhaps it was the explosion when Skolrick just died, or perhaps it was the tension of facing a high-level demon alone. He hurriedly calmed his mind and tried to think of a way from Skolrick's persona.

Arrogant and persistent, handsome skeleton, loves music, understands Soul Releasing Song…

“I don't expect you to understand the cultivation of skeletons…” Li Yue still held the bone sword, and at the same time picked up the lute on the side, “Nor will I explain to you what the Soul Releasing Song is, what the Song of Decay is…”

Hearing “Song of Decay,” the skeleton surrounding Budiboge moved, its palm turning blood red instantly, but it quickly disappeared.

“If you don't have any other nonsense to say, then get lost. I hope you can survive tomorrow night.” Li Yue tried to issue an eviction order, and also had a bit of confidence in Budiboge's departure—as the rib of the Skeleton King transformed, the Demon Son who was about to participate in closed-door training, Budiboge had no reason to attack Skolrick.

Moreover, Budiboge was about to go to the territory of another powerful demon. In theory, he should be very nervous now and would not waste his energy on some meaningless places.

Most importantly, Budiboge's malice had not reached the level of taking action, which was why Li Yue dared to continue acting and did not immediately “Summon.”

Although Li Yue didn't know what he could “Summon.”

“Ugh…” Budiboge groaned, seemingly not wanting to be subjected to Li Yue's mental attacks any longer, and left the entrance of the thirteenth archive room, retreating from where he came.

However, although Budiboge retreated from the middle level, the oppressive thought that enveloped Li Yue did not dissipate, still firmly surrounding Li Yue—Budiboge did not end his gaze.

The continuous analysis of the Demon Illustrated Handbook also proved this point.

Li Yue didn't panic. First, he casually cursed “idiot,” then collapsed on the large sofa, put down the bone sword, and began to play the “Song of Decay” according to his memory.

Acting, he had to act the whole part.

The sound of the playing rang out, the moonlight changed, and by the time it cycled to the fourth time, Li Yue's analysis progress had reached 6%, and the oppressive feeling finally disappeared into nothingness—Budiboge had really left.

【Analysis interrupted… Save record… Failed…】

【Overwrite existing record?】

The Demon Illustrated Handbook popped up a new prompt. Li Yue thought for a moment and discovered the problem—at this moment, the system saved the analysis progress of the Demon King, the Lesser Demon Secretary, and the “Slave Owner” Bode Kerry, reaching 3…

Could it be that 3 is the upper limit?

Who to delete?

The Demon King's definitely couldn't be, after all, he had met him few times and the record was the most precious. As for the remaining two… Li Yue thought for a moment and felt that only the analysis difficulty of “Slave Owner” Bode Kerry was not high and could not be saved; Budiboge was the owner of the library, and analyzing him earlier would definitely be most helpful to recent actions…

So Li Yue deleted Bode Kerry's record and retained the records of the Demon King, the Lesser Demon Secretary, and Budiboge, understanding the logic of the Demon Illustrated Handbook even more—encouraging the host to collect more demons, providing the function of transforming and even summoning otherworldly demons, but also having times when its ability was limited.

For example, saving records, for example, the form transformed into, although it was a physical entity, it was not completely “real”—according to Li Yue's understanding of the Song of Decay, this Soul Releasing Song had a body-washing effect on the bones of the skeleton race, but when playing, the transformed bones had no reaction to the Song of Decay, obviously Li Yue had no way to improve through this method.

After confirming that Budiboge was no longer watching him, Li Yue stopped playing, picked up the magic emblem that had just fallen under the corridor, and looked back at the bone sword by the sofa, examining the spoils of this battle.
