I'm a monster in Demon King's Castle

Too late to deal with the flies, too late to look at the "Octopus Morph" in the Demon Illustrated Guide, and regardless of the "Action Prediction Success Rate," Li Yue quickly found the attack route of the Earth River, driving the Self-Healing Bone and Binding Thread, forcibly shifting Buddybooge's main body by an inch.

Just one inch, avoiding a fatal blow.

"Poof…" The Self-Healing Bone was pierced like paper, as was the audience stand behind the Bone Cabinet, where Li Yue was.

The arena seemed to freeze for a moment, all the demons hearing that soft sound, and then seeing the Bone Cabinet, which had shrunk by more than half, fall apart and crumble.

Immediately afterward, cracks began to spread on the walls beneath the audience stand, creaking and groaning, the platform trembling slightly; from Corey's perspective, for a moment, he could see the eerie moonlight outside the arena through the pierced Bone Cabinet.

"Awoo—" The demons in the audience thought Buddybooge was dead and began to scream wildly.

But they didn't hear Oogey Boogey's announcement, and only then did they turn their attention back to the vicinity of Li Yue's audience stand, and saw, within the layers of peeling Bone Cabinet, a dark brown Brain Spirit floating alone, stripped of all external possessions, leaving only a Bone Sword.

At this moment, no demon doubted that it was a Brain Spirit participating in this battle; however, in the middle level of the audience stand, a burly skeleton seemed to sense something, and his body trembled.

"Kill him, kill the Brain Spirit!" The audience clamored again, repeating only these two sentences over and over.

Corey, having broken through the Bone Cabinet, finally breathed a sigh of relief, but did not relax his attack—as a seasoned gladiator, he would never let his guard down even when his opponent was at their weakest, nor would he give his opponent the slightest chance to breathe.

【No more shell… You're finished, Brain Spirit… Come… Let me hear the delightful sound of you shattering…】

Corey, with half his body buried in the earth, instantly scooped away a piece of barren soil, and the remaining four intact tentacles released gravel again, stirring up a gravel storm beneath the audience stand.

And Li Yue had already read Corey's reaction in the Demon Illustrated Guide, even before the gravel was released, he had replaced Buddybooge with a brand new "Heavily Armored Strongman"—since the Bone Cabinet had seven layers, then there wouldn't be just one "Heavily Armored Strongman."

After a burst of crackling and shattering sounds, the Brain Spirit did not die as they wished, but the audience stand swayed precariously under the intense attack, dust flying everywhere, and when the dust cleared, an even more horrifying scene appeared to the demons…

Three Bone Cabinets stood side by side beneath the audience stand, although the outer layers were battered and unrecognizable by the gravel, the main bodies were undamaged, and even trembled, as if taunting Corey.

【What's going on… This kind of mutation…】

Corey himself had experienced the "mutation" of demons, so he subconsciously considered the same possibility, but his lack of imagination made it impossible for him to associate everything that was happening before his eyes with a certain skeleton upstairs.

"Ha—too bad—this is the first round—" Oogey Boogey's voice sounded at the right time, filled with strong pleasure and satisfaction—Buddybooge was really good, fighting vividly, quite tense.

Hearing Oogey Boogey's announcement, the audience stand was naturally filled with wailing, and some clumsy demons even began to calculate silently, thinking that in this way… the Brain Spirit could at least last until the fourth round, and hurriedly went to add bets to the Fly Demons in the stands.

And Li Yue, taking advantage of the gap between the two rounds, went through Corey's information in the Demon Illustrated Guide, focusing on looking at "Weaknesses," and was stunned to find that this "Octopus Morph" had 4 hearts, even more than pure-blooded demons.

Two of the 4 hearts could be fatal—one was the octopus's "Body Heart," responsible for supplying blood to the octopus parts of his body, and the other was Corey's human heart, responsible for supplying blood above the chest cavity, while the remaining two "Gill Hearts" filtered and absorbed matter and magic, and discharged impurities.

As for the "Earth River" that was extremely similar to the Elephantine Siege Beast, Li Yue also found its origin in Corey's "Birth History"—the demon relic that Corey absorbed came from the Abyss's Great Maw, the excrement of a certain Siege Beast that had undergone a "mutation," and was transported to the vegetable garden where Corey obtained it, also helping him successfully complete the leap from Vegetable Person to Gladiator.

Li Yue didn't have the leisure to think about why a "Demon-level" demon would have a Birth History, what he was thinking about was how to quickly return him to nothingness.

Heart, huh… Li Yue aimed at Corey's "Body Heart," preparing to send the "Octopus Morph" on its way in the second round.

This break was different from Li Yue's debut, it seemed that Oogey Boogey had deliberately extended it in order to let the demons place their bets, so Li Yue also had plenty of time to predict and plan, and unprecedentedly comforted Buddybooge.

"Boss… Head of the family… Can… Can all this… be over… I… I can't take it anymore…" Buddybooge transmitted tremblingly—although he could know from his limited memories that he would win in the second round, he was also very uneasy after experiencing so many terrifying attacks.

"How are we going to… cooperate with Oogey Boogey… how to cooperate… with it?" Buddybooge signaled Li Yue to look at Corey.

Through Buddybooge's perception, Li Yue "saw" a fly in Corey's right shoulder, turning from transparent to red.

And having endured the restrictive first round, Li Yue breathed a sigh of relief: "Yes, don't worry about that fly, you just need to open your heart and accept my control over you."

Finally… it was time to fight back.

At this moment, Buddybooge was under the audience stand—this distance was enough for Li Yue to directly control the Lord of the Brain Spirits, and also directly control the three "Heavily Armored Strongmen."

It seemed that the demons had placed enough bets, and Oogey Boogey's voice came again, the long-awaited sentence for all the demons, "The second round begins."

The three "Heavily Armored Strongmen" pressed towards the "Octopus Morph" not far away like three small mountains, while bone spurs shot out in all directions, attempting to consume Corey's mucus; Corey sank into the barren soil to change direction, dodging the downward pressure of the three Bone Cabinets, while stirring up a gravel storm, both interfering with the direction of the bone spurs and weakening the Bone Cabinets' defense, while searching for the Brain Spirit's true form.

The battle entered a white-hot state the moment it began, with no more probing or dodging, purely a close-quarters life-and-death battle.

And Buddybooge, riding in the "Heavily Armored Strongman," was like riding a roller coaster, sometimes finding himself outside the storm, and sometimes drilling into the eye of the hurricane, with absolutely no control.

The audience also didn't expect the Brain Spirit's counterattack to come so fiercely, as if completely changing its fighting style, and for a time could only see bone fragments and gravel flying around the arena; only a few with sharp eyes saw the countless wronged souls rising in the center, and the Bone Sword that stabbed straight at Corey's heart.

"Undead Lament" and "Withered Thorn," Li Yue used them all.

When large swathes of mucus were torn off by the countless wronged souls gathered in the arena, when the main body of the "Octopus Morph" Corey was dragged out of the barren soil and twisted in mid-air…

That Bone Sword, surrounded by deathly aura, found a path through the intricate bone spurs, stabbing Corey's heart from the air!
