I'm a monster in Demon King's Castle

That was the first time Li Yue, Yingying, and Egg Egg went shopping in Death Town, Desler, and robbed an invitation to a demon masquerade after raiding the auction house.

The invitation was imprinted with the emblem of a "wine glass" in blood, representing the Interlude of Delight.

They hadn't used it since they snatched it back then. Yingying had been storing it away as if it were at the bottom of a box in her shadow space, and it was almost integrated with it—after a long expedition, the invitation was already somewhat torn, but unexpectedly, the writing gradually filled in, turning back into a complete invitation.

Li Yue discovered this when he was going in and out, carrying the bone guide cannon, and felt that it might be useful.

Oogie Boogie might be hiding in the Interlude of Delight, and the invitation to the demon masquerade is undoubtedly a proper ticket to the Interlude of Delight.

"To welcome the upcoming year 300 of the Kai calendar…" Li Yue read the words on the invitation and realized that the New Year of the Chaos Continent was approaching without him realizing it.

When he first arrived in Demon King City, it was the third full moon of Kai calendar 299. At that time, he was just a small brain spirit trapped in the arena; now, more than half a year has passed, the library is thriving, the spine of the continent has collapsed, the expeditionary army has collapsed, and humans are about to attack Demon King City.

But the demons in the city are still in the mood to dance.

"Also, to celebrate the victory of the expeditionary army, we will start a demon masquerade with no time limit…" The invitation was created by demons and is not limited to a specific masquerade at a specific time, but rather a right to enter the masquerade, with no expiration date.

"Endless fine wine, inexhaustible beauties…"

"Sincerely invite lovely people, monsters, and demons to attend…" Li Yue pondered this line and realized that the demon masquerade was not limited to demons only, and it was possible to meet humans and heroes at the masquerade?

Even nobles, royalty?

However, the nobles of the Tas Empire are currently busy taking over the power of the Holy See, so they probably don't have time to participate?

"Here, you can convert to demon worship, exchange sacrifices, and exchange slaves…" Obviously, the demon masquerade is not just about dancing.

And the slaves exchanged here will definitely exceed the quality of those seen in the demon market.

No wonder there weren't many big shots at the demon market auction, at most just a few second-generation skeleton scions…

It turns out that the really rich guys are all in the Interlude of Delight.

"Of course, there are also dances that are absolutely not pure, the most prestigious guests, and the most novel ways to play, to satisfy all your expectations for enjoyment, socializing, and pleasure!"

Seeing that the dance was not pure, Li Yue suspected that this might not be attractive to the Skeleton Clan.

He also didn't know if the demon masquerade was brain spirit-friendly.

"This is an exchange, but also a grand event! We are waiting for you, in the Interlude of Delight~" At the end of the invitation, there was a nightmare succubus shape outlined in blood, winking at Li Yue.

The nightmare succubus winked, flapped her wings and stretched out her hand, constantly flipping her palm, as if it were some kind of invitation.

"Go!" Egg Egg had played with Nate Meier during the closed-door war training, and at this moment was very much looking forward to what kind of joy the demon masquerade could bring.

"Go." Yingying looked back at Demon King City.

The Interlude of Delight was originally where Oogie Boogie might be, and since there was an invitation, of course they had to go.

Li Yue had almost finished cutting up the meat bun on the ground, and also analyzed some monsters such as Venus flytraps, brain-eating insects, and leaf people, but he didn't see anything interesting drop, and didn't receive any demon points.

Li Yue first left a line of words for the Forest Keeper, indicating that when sending sacrifices next time, there was no need to send duplicates, saving time.

"Let's go, let's go!" Egg Egg urged.

"Don't worry, it's a masquerade, you have to prepare." Li Yue has never had a sense of security, and this time he was going to the Interlude of Delight controlled by the nightmare succubus. The shadow was fine, but the brain was quite dangerous.

"You have to lie to yourself first, you are not the Lord of the Authority of the Library." Li Yue instructed Egg Egg.

Li Yue was already familiar with how to bypass the iron law of Demon King City.

In order to help Egg Egg get into character faster, Li Yue even took out a bit of faith source that he had saved up—most of the malice collected from the Forbidden Forest these days was used to make creation materials, and he only saved this much.

"I am not the Lord of the Authority? Then who am I?"

"You are Hannibal, from the banks of the Rund River in the north. You are a doctor who came to Demon King City to improve your medical skills and is very familiar with the arena…"

Li Yue felt that since it was a masquerade, they definitely couldn't just go in and be silent like three autistic people. He thought of some small talk in advance, so at least others wouldn't suspect their intentions as soon as they came up.

And Hannibal was indeed very familiar with the arena.

"What about me?" Yingying asked about her background story.

"You are Don Quixote, once a Celestial Dragon… oh no, that's not right…" Li Yue almost switched channels, "You are a knight, the knight Don Quixote from the banks of the Rund River, also a ranger. You are dissatisfied with the injustice in the world… oh no, you believe in justice a little bit, but you have realized that you can't shatter all the injustice in the world with just the javelin in your hand…"

"A fallen knight, is it?" Yingying found Li Yue long-winded.

"Yes."

"Also from the banks of the Rund River in the north, very curious about the arena, because that is the final destination of knights." Yingying automatically supplemented Don Quixote's persona, "This way, it will be more convenient to inquire about the whereabouts of the King of the Arena."

"Wonderful! That's what we'll say!" Li Yue very much enjoyed this feeling of not having to use his brain too much, and also missed the days when he had the "Completion" card.

"What about you?" As companions, the three naturally had to understand each other's stories.

"I am Van Helsing, a demon hunter from the banks of the Rund River." Li Yue used his shadow to control Van Helsing's skin, "When I was still an Iron Bucket in the arena, I teamed up with Jesse to smash the lounge and seriously injure Beelzebub!"

Identity is fake, but achievements are real.

Li Yue felt that not hiding Van Helsing's identity would make it easier to arouse the attention of some demons related to the arena—this time he was going to the demon masquerade not to dance, but to find Oogie Boogie, so of course he had to be efficient.

Otherwise, was he going to accompany humans and demons to dance and celebrate the New Year?

"It's just that I was injured at the time and rested for a while. Now I'm back and looking for the King of the Arena!"

"Okay!" Egg Egg was very excited after hearing this, "Let's go!"

"Hannibal, you have to be careful, especially of the nightmare succubus." Li Yue felt that he still had to tell Egg Egg before leaving, "Don't enter their dreams, otherwise if they read your memories, they may notice something…"

Li Yue wasn't sure what was in Egg Egg's head now, and he wasn't sure how far the nightmare succubus could see.

"Heh…" A foolish smile appeared on Hannibal's square face.

Li Yue panicked even more, and firmly grabbed Hannibal's shadow, ready to separate his brain from his body at any time—once inside the Interlude of Delight, even if Egg Egg accidentally fell asleep, he could wake him up directly and put him in the shadow space, which should ensure safety.

At least with the malice prompt from the Demon Illustrated Handbook, he could prepare for danger in advance.

Bone spurs pierced into a stone, Li Yue marked a new teleportation point on the demon navigation route, and also left a message for the Forest Keeper. With everything prepared, it was time to go to the Interlude of Delight.

Right, how to get there?

The Interlude of Delight was an unfamiliar area. The map that Jesse initially bought didn't mark it either. Li Yue only knew that there was a wine glass emblem on the door of the entrance.

"Touch her hand." Egg Egg seemed to understand the lip language of the stick-figure succubus on the invitation, and signaled Li Yue to raise his hand.

Li Yue used his shadow to connect the three sons of the devil, and his fingertips touched the small blood hand.

Then he immediately fell asleep and was dragged in by the succubus.
