I'm a monster in Demon King's Castle

“Buzz—”

The Holy Whip struck Egg, shattering a ground of flies.

Oogie Boogie's body exploded from a triumphant balloon into a chaotic mess of rags.

The compound eyes, bodies, and wings of the flies shattered together. The particles on Egg's body, at the instant of being struck by the Holy Whip, dispersed into countless metallic lines, spiraling outward from Oogie Boogie's center.

Ultimately, they formed an extremely regular "spiral" shape, sweeping away the sackcloth, chainmail, and dark human legs.

Simultaneously, the Bone Sea, at the moment Oogie Boogie was deceived, purged all footprints from its periphery.

Although large patches of self-healing bones became diseased, proliferated, and decayed, they quickly returned to their translucent white.

As for the scattered flies in the room, they were kneaded into meat paste by Shadow.

【How could I… I clearly won…】

The Colosseum King's invitation ticket also reset to zero at this moment. The casino did nothing, yet became the absolute winner.

Oogie Boogie died.

No materials dropped.

The Demon Illustrated Handbook did not pop up a kill success notification, and the Demon Points remained at 4.

Clearly, this was just a clone of Oogie Boogie in the casino. The three Demon Sons exhausted all their abilities, and could only defeat one in a frontal battle.

But the Demon Sons' emotions were high.

After all, this was Oogie Boogie enhanced by the casino.

If it weren't for the hundreds of thousands in funds bolstering him, Li Yue felt that a three-on-one fight would have a very high chance of winning.

However, he also had to consider whether Oogie Boogie had combination tactics or even more powerful sackcloth bodies.

In short, this time they won.

They won big.

Because the Colosseum was out of money.

“Are you okay?” Shadow rolled to Shadow's side, asking Li Yue.

Shadow was mottled and oozing white fluid. Li Yue also twisted Shadow constantly, fighting against the red and white plague.

“I'm fine, just need some time.” Li Yue instructed Egg to strengthen self-healing.

“What's that?” Egg ran to the spiral Egg body, rubbing it with its brain.

“Maybe it's your mature form?” Yingying was forcibly beaten into a spiral shape by the Holy Whip. Everything was determined by the body. At the time, all she could think about was shocking Oogie Boogie to death.

After the whip, the Egg body returned to its previous round shape.

“Let's switch back!” Upon hearing 'mature form,' Egg immediately didn't want to stay inside the brain anymore.

Having gone through the recent battle, Egg realized that it instinctively resisted the brain spirit's fighting methods.

What kind of fight is it if you can't charge up and ram?

“Who wouldn't want to switch back?” Li Yue also realized that in the recent battle, his control over Shadow's body was far less powerful than Yingying herself usually was.

He guessed that Yingying in the Egg had also noticed this.

“No matter when we switch back, before that, you must try to deconstruct more.” Yingying was very strict.

“Okay…” Although Li Yue looked forward to switching back to his body, he had to admit Shadow's convenience—while they were talking in the room, the Shadow Space was already constantly exchanging King Electric Horns.

Yingying and Egg tacitly took the King Electric Horns, threw them back into the Shadow Space, and stuffed them into the invitation ticket seed, working hard to help Li Yue repay his debts.

“How's the Library?” Unable to leave the casino for the time being, Li Yue asked Egg.

Finally, he still had to face Harry's fate.

“See for yourself…” Egg transmitted a broadcast to Li Yue.

The outer wall of the Library's upper level had closed. Beside the dozen or so Bone Guidance Cannons on display, Galarick, Mini Minnie, and the brain spirits surrounded a pool of magma, trying to pile the remnants of Harry together.

Menmen was opening the door, seemingly going to find Tom and the copper spoon to see if there were any other solutions.

But Li Yue already realized that Harry would not come back to life.

A gamble far away in the casino caused the death of a craftsman apprentice in the Library—the battle with demons was so irrational.

Although they obtained 260,000 equivalent Summoning Luck, eliminated a clone of Oogie Boogie, slowed down his pace of spreading the plague, and cleared out the Colosseum's assets as desired…

The three Demon Sons couldn't be happy seeing such a scene in the Library.

“Are you preparing to leave?”

The figure of Red-Robed Priestess Otrna appeared at the door.

This casino automaton had fled the gamble at the start of the battle, only returning after it was over.

“Yes, the goals have been achieved, we'll leave after repaying the debt.”

Li Yue stared at the amount on the invitation ticket, waiting for it to go from a long string of negative numbers to zero—the casino's debts seemed more reasonable than the merchant's, not so prone to skyrocketing interest.

“And you… are you still preparing to sacrifice yourself?” Li Yue asked Otrna.

“Of course.” Otrna finished speaking, picked up a splintered piece of wood from the ground, and directly stabbed it into her throat.

No blood spurted out.

Otrna was like a nail inserted into a wall crack, her body suddenly contracting, turning into a red coin.

A worm was carved on the coin.

At the same time, Li Yue's debt increased again, the amount being one hundred thousand.

“His Demon Cocoon… as expected, I still have to pay the bill…” Li Yue increased the level of exchanging King Electric Horns, accelerating debt repayment.

Fortunately, he gained a lot of malice in the battle with Oogie Boogie, otherwise just repaying the debt would be enough to give the Demon Sons a headache.

“Can this coin summon Old Butt?” Egg stuffed the coin into a brain groove for safekeeping, lest it accidentally fall into the Shadow Space.

“If she says it can, then it can, huh?” Li Yue draped the velvet-robed skeleton skin back on, covering the gurgling white fluid and cracks on Shadow's body, lest Yingying feel distressed.

“After all, she's a corner of the Grand Altar…”

Being in the casino, having just killed Oogie Boogie's clone and destroyed the Colosseum's underpants, Li Yue deconstructed the coin and suddenly realized that he seemed to have come into contact with the core circle of Demon King City.

Even a corner of the Grand Altar, a former Demon Son, was asking him to help ask the Demon King mentor questions. The King of the Colosseum was also shocked to death by a spiral. Perhaps it would be difficult to hide in the shadows of the Library and stir up trouble again.

Not to mention the near future, the fate of the three Demon Sons had already been connected to the casino, the dream between joy and pleasure had also spread to the Library, plus the contract with the Forest Keeper, the coveting of the Colosseum…

Everything was gradually becoming uncontrollable.

“Once that Old Butt is summoned, what do you want to eat?” Egg was now a brain, but already thinking about ordering dishes.

“We don't necessarily need to summon Mentor… If the Summoning Luck we won is useful, we shouldn't meet him.” Yingying wasn't as impulsive as Egg.

Firstly, because Yingying's "Advancement Study" was already clear, without additional questions; secondly, the Chaos Flower in the banquet gave Yingying a great sense of unease.

Clearly, Mentor also needed a source of faith.

The Demon King mentor was willing to share the source of faith with Egg, but that didn't mean he wouldn't extract the source of faith from Shadow's body and absorb it himself.

Especially since Li Yue's Shadow body was infected with the plague and needed a lot of time to heal.

Some time had passed since that banquet, and no one could determine whether those big shots had eaten their fill.

“Hopefully 260,000 Summoning Luck won't disappoint us, and can summon an 'absolutely neutral soul'…”

Li Yue looked at the Summoning Luck in the status bar, then looked at the 4 Demon Points he had obtained this trip, and looked forward to tomorrow's summoning results.

“Oops, forgot one thing, forgot to ask her… how to use this Summoning Luck.”

Li Yue wasn't sure if each summoning would consume a certain amount of Summoning Luck, or if it would just hang there, permanently valid.

Otrna definitely knew.

“I know how to use it.”

The room suddenly rolled, the six walls flowed, twisted, as if something was about to drill out.

【Parsing… 2%…】

The Demon Illustrated Handbook popped up a notification.

“Hey, now that you're here, don't you want to say hello before leaving?”
