I'm a monster in Demon King's Castle

"What cloak? What's the benefit?" Egg and Shadow each trembled. Li Yue suppressed his shock and asked.

How did Fusi know there was a cloak in the library? Why did he say he could open it within three days? What's inside?

The blue-purple cloak next to the Soul Altar had always been a question in Li Yue's mind, and it was also one of the two major mysteries of the library, along with the Thirteenth Archive Room. How could it be solved as soon as he encountered the Fire Ember Valley Prophet?

"I don't know about this…" Fusi was also very cautious in controlling his prophecy. "If I probe further… I will die…"

[Unknown… what… cloak… ]

Fusi's thoughts relieved Li Yue's worries a little, and he turned to think about the reason for the change in the cloak—Li Yue had been exploring the cloak, but after obtaining the Brain Core's 'acceleration,' the cloak seemed to sense the prying of intent and became even more tightly sealed. Even now, Li Yue has not been able to probe the core.

Of course, part of the reason was that Li Yue had been very busy in the middle and had no way to explore at all times, but now that Fusi said it so lightly, it always felt like there was a problem.

"Otherwise?" Li Yue continued to ask, "I mean, what if it's not opened within three days?"

"Otherwise, you will die," Fusi said with certainty.

Li Yue's brain furrowed.

But no matter how Li Yue asked, Fusi would not explain further—anyway, the contract had been signed, and Li Yue had to send him to the Demon Market.

"Alright…" Li Yue led Fusi to the Sixth Archive Room, preparing to put the Fire Ember Valley Prophet back through the toilet pit.

On the way, Fusi also very sensibly burned away the memories of all of Li Yue's questions again. His mind was empty as he drilled into the toilet pit, turned into a cluster of flames, and left.

The Brain Core Fire sensed Fusi's passing aura, its interest waned, and it returned to the middle candlestick to continue 'soaking.'

And Li Yue didn't know whether Fusi would be caught again by the merchants in the Demon Market and auctioned off, or whether he would die on the Black Slope outside the town… but these had nothing to do with him.

Li Yue now just wanted to soak the Magic-Powered Motorcycle and Magic-Powered Cannon as soon as possible, and by the way, probe what exactly was inside the blue-purple cloak within three days—Fusi said that unlocking it within three days was most beneficial, which also meant that if it couldn't be unlocked within three days, there might be variables.

Thinking about it, Li Yue suddenly felt a sense of crisis, and he also felt that things were becoming more numerous—probing the cloak, new sensed objects, completing enhancement and advancing, the approaching Butler, the coveting of the library's authority in the dark…

There were also Egg and Shadow, who were about to join the Demon Expeditionary Force, the survivor Tom, who had already collapsed inwardly, and Mini and Minnie, who had the opportunity to leave Demon King City and return to their hometown to get married…

The library seemed to be about to undergo a major change again, in a short period of time.

Li Yue was silent, going over the things he had to do in his mind over and over again. Shadow suddenly displayed writing next to him.

"You want to take the 'Hellfire'?" Shadow asked.

"Yes, O'Keefy has tampered with it. I will have a battle with him sooner or later. If I kill him… Hellfire will be very useful." Li Yue only knew today that the 'Hellfire' was in the Abyss Maw, otherwise he would have asked Shadow long ago.

"I haven't been to the West Third Vein of the Blood Cocoon. When we go back, I can help you take a look," Shadow volunteered. "But if you want to explore the Abyss Maw in a short period of time, I want to be with you too."

[I can help you… ]

Li Yue certainly knew what kind of role a demon could play on its home field, but there might be problems in terms of time—if he went to find the 'Hellfire,' he must be fully prepared, at least to complete the next level of advancement to be safe; and what if the Demon Expeditionary Force had already set off before that, could Egg and Shadow still accompany him?

Moreover, the Abyss Maw was the territory of pure-blooded demons, and it was also when the expeditionary force was about to set off, so it must be heavily guarded. How could he just go whenever he wanted?

It would be best to explore after the Demon Expeditionary Force set off, when the Abyss Maw was relatively empty…

Li Yue was thinking, and Shadow, seeing that he had no reaction, suddenly wrote a line of striking and surprising words: "By the way, do you remember the 'door' in the upper cave? I guess… it leads to the Abyss Maw."

"What?" Li Yue didn't expect that bombshells would come one after another—Shadow had already said that the broken space outside the upper layer was a 'door' when he killed Budi Borg earlier, but he didn't expect it to lead to the Abyss Maw.

Was this fate arranged long ago? Or was it a coincidence?

Li Yue had a bit of a stress reaction—why was the library connected to the Abyss Maw? These two places were obviously unrelated. It would be understandable to say that it was next to the laboratory…

"I'm guessing, because I'm very familiar with the aura of that place, and I'm only familiar with the Abyss Maw," Shadow remembered this only after hearing about Hellfire. "So we can try… to go directly from the upper layer…"

[Before the expedition… I want to be with you every moment… ]

"By the way, when are you and Egg… going to join the army?" Li Yue asked, hearing Shadow's thoughts.

"I have already received the summons from the Abyss Maw, ordering me to report within three days…" Shadow wrote, pulling out a piece of lava full of information from the shadow space.

Wait a minute, three days again?

Could it be that the change in the blue-purple cloak… is related to the Demon Expeditionary Force?

Li Yue was full of doubts again, thinking that perhaps only by unlocking the cloak could he figure out the relationship between the Abyss Maw, the library, and the Demon Expeditionary Force.

"Okay, I understand…" Li Yue roughly sorted out the current situation—exploring the Abyss Maw was a must, but the time was not so urgent yet, at least he would consider it after he completed his advancement and the library's defense was worry-free.

Li Yue had no way to control this. If it really didn't work, he could only give up Shadow and Egg's company and go to the Abyss Maw by himself.

But Li Yue didn't think… that he would have the ability to bring back the 'Hellfire' just by taking a trip to the Abyss Maw.

The first time was exploration, not robbery. Without understanding the real situation of the Abyss Maw, there was no need to consider it so carefully; instead, the piercing project of the blue-purple cloak needed to be placed after the advancement, as the second priority, to reach the most 'beneficial' situation first.

"We'll kill the Butler, and when we come back, you'll help me 'advance,'" Li Yue telepathically conveyed to Egg and Shadow—Shadow had shown Li Yue the danger of the first advancement, and Li Yue felt that it was still very necessary to have these two demon sons protect him.

And in case a Butler with a dagger came to kill during the 'advancement' process, it would always be troublesome, so it would be better to solve it first, and then try in a relatively safest environment.

As for the library's defense during the advancement… it could only be handed over to the closed Bloody Corridor, and Budi Borg, who could barely call the library's magic power, plus the Staff of Deception.

Failure in 'advancement' would naturally lead to death, but if it succeeded, Li Yue could soak the Magic-Powered Motorcycle and Magic-Powered Cannon while Egg and Shadow watched, and open the blue-purple cloak that he had been curious about for a long time.

"Oh, kill the Butler… you don't need to do this kind of thing. You prepare well here, we'll kill him now and come back to find you…" Shadow wrote, and added another line.

"By the way, we will also bring back his dagger for you," Shadow remembered Li Yue's habit of collecting demon relics.

"Yes! Friend, you just prepare the bath pool and wait for me to come back for a hot lava bath!" Egg didn't quite understand what Li Yue and Shadow had just said, and didn't care, only knowing that something very interesting seemed to be about to happen.

Li Yue pondered for a moment and agreed to Shadow's arrangement—compared to advancement, the cloak, Hellfire, and the future transformation of the library… a Butler from the Demon Market was already the most insignificant thing, and there was no need to waste time.

"It's not necessary to have the dagger. You solve him and come back as soon as possible," Li Yue let Egg and Shadow go, moved to the Bone Chamber reception room, and arranged the advancement scene for a while.

Li Yue stuffed the Magic-Powered Motorcycle, Magic-Powered Cannon, Staff of Deception, and other things into the Freak Jigsaw, threw them into the middle layer of the library, avoiding any unnecessary interference, and then floated in the Bone Chamber reception room, leaving only the Bone of Self-Healing, Bone Sword, and Brain Core Pituitary Gland as sensed objects, and materials produced by the Demon Illustrated Handbook such as Demon Wolf Fang, Binding Thread, Lava Right Hand, and Octopus Tentacle, to deal with possible problems during the advancement process.

"You sleep, I'm going to conduct a cruel—cruel scientific experiment on you," Li Yue summoned a fragmented Galarec and ordered him to sleep.

"This is my glory," Galarec waved his tattered arm and saluted.
