I'm a monster in Demon King's Castle

In that instant, Li Yue vaguely felt a tremor in the Colosseum's space, and this tremor… was extremely similar to the shattering when he first encountered the altar on the upper level!

[Deception… ]

Manderna had indeed launched Deception, but Li Yue was still one step behind in noticing.

In a flash, Li Yue saw the scene near the gnoll camp and was stunned to discover… that the cave entrances were all barren soil! The barren soil of the Colosseum!

Truefire poured onto the barren soil, roasting a real wild boar, emitting a fragrant aroma…

Thinking of Manderna's "switching" deception, Li Yue couldn't help but guess that Manderna had directly folded a part of the Forbidden Forest… into the Colosseum?

Misunderstood, the scope is not small—Li Yue brought the Son of Evil to participate in the battle, while Manderna directly moved the home field over?

Next, the barren soil of the cave entrance slightly overlapped with the forest in the arena, and the wild boar appeared, who was none other than the mind gnoll Manderna—his mane also transformed into the Staff of Deception, held in the old gnoll's hand.

The old gnoll was about to break free from Yingying's restraints, and only needed to take one step back to retreat into the cave entrance of the gnoll camp.

The only good news was that the death aura of the bone sword was entangling Manderna's thigh, still spreading continuously; it was just that when Manderna took that step back towards the cave entrance, it suddenly converged and gradually showed signs of fading.

Escape?

Obviously, if Manderna took this step back, the effect of the Thorns of Decay would also be about to end—next, Manderna could choose to return to the Colosseum to participate in the battle, or hide deep in the cave, no longer giving Li Yue another chance to kill him.

What a powerful demonic relic…

"Throw the egg…" Li Yue only had time to transmit this thought to Yingying.

With the same spatial shattering, Li Yue chose the same method of handling it, just to see if Dandan could understand.

And Manderna could exchange space, Yingying could also, like the Forbidden Forest, send Dandan to the old gnoll's side in an instant—Li Yue thought… this was also a kind of belated arrival.

"Don't even think about leaving!" Dandan had already experienced it once, appearing next to Manderna like a magic needle that holds the sea, firmly suppressing the shattering of space while enduring the baptism of wind, thunder, and Truefire.

[Huh?]

Finally, for once, Li Yue instantly received Manderna's thoughts.

He panicked?

[They… are with Boodiboog… the Son of Evil!]

[Malice +7444]

On the other side, the gnoll leader's wolf tooth club and Galarick's octagonal club clashed again, emitting a loud bang that also cracked Boodiboog's killing sea butterflies.

The dark brown brain spirit dripped out of the stone shell, twitching and scurrying everywhere…

But strangely, not a single killing sea butterfly went to rescue it, as if it were the most ordinary brain spirit.

[Boodiboog… that's Boodiboog… is it… could it be… this?]

Manderna couldn't understand the brain spirits' actions—clearly all the brain spirits acknowledged that it was Boodiboog, but there was no rescue, which could only mean… Boodiboog was no longer the master of the library!

And when Manderna shifted his gaze to the unruly skull in front of him, he vaguely understood who was leading this battle.

This was just the mind gnoll's lightning-fast thought; now that he knew he had chosen the wrong opponent, he had no choice but to protect his life.

[There's no way… I can only… deceive… Death… ]

Even if he moved a corner of the Forbidden Forest to the Colosseum, Manderna had no way to find any helpers, and could only face the constantly sweeping death aura alone, unleashing his final strength—the Staff of Deception flickered again, and Manderna shed the skin of the gnoll, and in an instant, his bones were exposed, as if he had changed into another species.

But Li Yue, with the bone sword in hand, used the False Seat Authority to suppress this change at the first moment—even if Li Yue couldn't distinguish who Death was, the bone sword knew.

"You chose the wrong object to deceive…" Li Yue transmitted the thought, octopus tentacles wrapped his entire face to prevent Manderna from fighting to the death, while simultaneously increasing the strength in his hand, the bone sword pierced the mind gnoll's thigh!

[Skull… Authority… Scourge Rick!]

[The brain spirit has become a slave of the skull… is it… ]

[Malice +5444]

This was Manderna's last thought—immediately afterwards, the death aura spread to the mind gnoll's entire body, gradually completing his devouring and decomposition.

"There's no way to deceive Death, huh?" Li Yue chuckled, accepting this malice, plus the malice of the gnoll family.

[Killed a high-level demon… ]

In the Demon Illustrated Handbook's prompt, Manderna fully withered, gradually generating exudates; Li Yue changed the angle of the tentacles on his head, expanding the coverage of wind, thunder, and Truefire, trying not to let other gnolls disturb him.

Dandan also took a happy bath inside, knowing that next, he could just kill them at will.

These were just the changes that took place in the Colosseum in a short period of time—the audience only saw an egg suddenly appear in the shadow, and the wild boar turned into a hunched old gnoll, and then died in a blaze of thunder and fire.

After the old gnoll died, the forest in the arena also turned back into barren soil, and also brought a fragrant roasted wild boar—the magic effect of the Staff of Deception dissipated.

Li Yue seized the time, taking the bone shell and "biting" towards Manderna, and while killing him, he also wanted to take the Staff of Deception and the materials he dropped into his bag.

But at this moment, a sudden change occurred—the human skin that Manderna had been draped behind him… suddenly窜out of the coverage of wind and thunder, and floated towards an inconspicuous human on the barren soil!

Yingying, on the other hand, fell silent after controlling and transferring Dandan in an instant, unable to help Li Yue freeze the human skin.

Li Yue knew that it was the gnoll trickster Masna, the Masna who had the "Skin of the Weirdo" drop—was the human skin his? What happened?

At the same time, the battle finally entered the white-hot frontal stage, with Galarick and the gnoll leader fighting intensely, constantly scattering bone matter; the gnoll family still believed that the dark brown brain spirit was the Brain Spirit Lord Boodiboog, and two hundred of them launched a siege together.

The red-robed priest Reidkort had only just prepared the ritual, and at this moment, he was chanting words and walking counterclockwise around the arena; and the minotaur who was released by Yingying in the second place, at this moment, seemed to have finally found his target and pounced towards Galarick, who was fighting fiercely with the gnoll leader.

The battle fully unfolded, and Li Yue also completed the positioning of Flayner, Elana, and Masna, only wanting to quickly snatch back the human skin behind Manderna, and also get Masna's "Skin of the Weirdo"—although Li Yue didn't understand what was going on, he was sure that both skins were good things.

For Li Yue, the remaining battle was not difficult, and the killing sea butterflies' formation had been practiced for half a month, and they could exert their maximum effect with a little guidance; on the contrary… collecting the spoils was the most important thing.

The gnoll family's demonic relics, the dropped materials… all had to be taken.

When Li Yue killed Manderna and began to busy himself in the arena, the audience finally no longer needed Oogie Boogie's live broadcast, and finally got to see a blood-splattered war as they wished—constantly, tricksters' skins were torn apart, gnolls were dismembered into eight pieces, and bone shells were crumbling under the gnolls' bites, embedded in the barren soil like death.

Overall, it seemed that the gnolls were at a disadvantage, like a group of insects趴伏on the barren soil, leaving lines of accusations with blood; only one brain spirit was being chased by twenty gnolls, repeatedly leading the gnolls into the killing zone composed of six bone shells.

That was Boodiboog, Boodiboog who was focused on running away.

Only a few special gnolls and a minotaur were fighting well, one of the gnolls could fly, constantly freezing those seemingly invisible bloodlines, slowing down the bone shells' actions; and there was also a gnoll whose eye demon on his shoulder seemed to be one with him, able to emit various rays…

It was just a pity that every ray was blocked by an egg, making the egg make noises, happy noises.

"Huh? Boodiboog? Changed the way of playing?" Oogie Boogie was not sure that the one scurrying around in the arena was the Brain Spirit Lord, and he increasingly couldn't understand the battle of the Slaughter Cup.

And Li Yue himself was chasing Masna vigorously—Manderna's human skin had already been draped behind Masna, killing one to get two, he must take it down…

Strangely, the human skin seemed to have fused with Masna's skin to some extent, and the surging magic power also made Li Yue increasingly anxious.

Could it be a "mutation"?

And on the other side, a "mutation" was already happening.
