I'm a monster in Demon King's Castle

“Finally out…” The two magi-armored knights entered first, gazing at the grim bone-chamber reception room, and for a moment felt something was off—this and the library the master described… seemed a little different?

Shouldn't there be stairs after passing through a corridor? Stairs leading to the middle and upper levels?

As the two magi-armored knights were thinking, the gray robe and the beholder aberration also entered with a group of fly-bugs, followed by the closing of the bone door behind them, and then its disappearance—Li Yue was remodeling the terrain of the bone-chamber reception room in real-time, not even leaving them a door.

The fly swarm was momentarily confused, forming a giant question mark.

After that, their attention was drawn to the bone throne—the throne sank, and a cavern appeared, taking up almost a third of the reception room, then a giant brain rose from the cavern, and as it revealed its full form, the cavern closed directly, and the bone-chamber reception room returned to its sealed state, with no entry or exit.

At the same time, Li Yue used "Deception" to temporarily cut off the fly swarm's shared vision with Oogway, which also consumed a large amount of magic from the library.

【Buddy Bog… ?】

The fly-bugs swarmed chaotically, and Li Yue read the horror in their hearts.

The four gladiators were also stunned, of course—wasn't the Brain Lord in the arena? Then who is this in front of them?

Moreover, if a comparison were to be made, the Brain Lord on the bone throne was clearly more real, right? The bones embedded in the flesh, the brain grooves inlaid with magic wolf teeth, the abruptly existing "Heavy Armored Maniac"… all reminded the invaders that their doom had arrived.

Li Yue didn't use Deception this time when he appeared; his main body was sitting inside the Brain Lord, his bony hand gripping the Staff of Deception.

At the thought of facing the Brain Lord in the library, the four gladiators felt it was beyond their capabilities, unsure of how to react, and all looked towards the fly swarm behind them.

Li Yue's appearance achieved its purpose—to overwhelm with a show of force.

And the horror in Oogway's heart hadn't dissipated—he could only confirm that Buddy Bog was participating in the Slaughter Cup tonight, but he couldn't determine what this was in front of him.

Could it be that the Brain Lord had learned to split his body? Or was it the effect of the Staff of Deception?

Oogway was filled with suspicion, and Li Yue didn't give him much time to react, simply using the Staff of Deception to teleport a short distance, suddenly floating above the fly swarm, and then pouring endless lava from the bottom of the brain!

Yes, first kill Oogway, then slowly deal with the four gladiators.

The fly swarm naturally scattered at the sight of the lava, but just at this moment, the ground moved, as if a bowl-shaped hand stretched out from below, lifting the entire fly swarm from below, actively reaching up towards the lava, completing a baptism of the fly swarm.

When the bowl was filled with lava, the fly-bugs inside stuck together, buzzing as they floated up and exploded, about to be completely wiped out; at the same time, the four gladiators eagerly wanted to sever the earthen bowl to rescue their master, but the magi-armored knights' weapons were blocked by the "Heavy Armored Maniac," and the beholder's various rays all landed on the tentacles' suction cups, dyeing the tentacles in various colors.

【What is this… lava… damn…】

Oogway was in disarray, knowing he could only rely on his own strength to escape, so the fly swarm wrapped into a fist, constantly tumbling around a red fly at the core, determined to smash a path through the lava!

And as the red fly broke out of the lava, about to regain freedom, Li Yue immediately activated "Dirge of the Dead" to grab the fly, and without hesitation used "Thorn of Decay" to annihilate the red fly.

The fly swarm was annihilated.

The four gladiators only saw the Brain Lord tear open its flesh to release lava, followed by a dark light shooting out from the brain grooves, withering their master's red…

【Too powerful…】

Li Yue used his strongest methods as soon as he attacked, coupled with the authority of the library, the Staff of Deception, and the bone sword, instantly beheading the leader who invaded the library, leaving only four gladiators to die.

From the moment Oogway entered the bone-chamber reception room to his death, it didn't even take a few seconds—this was the overwhelming advantage of an authority holder on their own battlefield.

Li Yue seriously suspected that if Buddy Bog hadn't used all the library's magic to heal, wanting to kill him on the upper level… would have been an impossible task.

The four gladiators stood frozen in place, as if their minds had been taken away; Li Yue slowly floated down beside them, saying nothing, just quietly watching, watching the beholder aberration, as if admiring a display.

The two magi-armored knights felt an immense threat, subconsciously gripping the weapons in their hands, and then immediately discovered that they had been "swallowed" by the Brain Lord.

Their hands were cut open by the "Magic Wolf Teeth," causing a bleeding effect. Li Yue thought this might be their destined way to die, so he directly sandwiched them in the brain grooves, chewing them thoroughly.

The strength of the freak patchwork wasn't something the magi-armored knights could break through in a hurry—soon, under the squeezing of the magic wolf teeth and the binding of the stitching, the magi-armored knights burst with blood from the brain grooves, their flesh and blood devoured, dripping onto the floor of the bone chamber.

That sound seemed to be knocking on the souls of the gray robe and the beholder aberration, causing their hearts to fluctuate sharply—the two magi-armored knights, who were good at melee combat, were eaten by the Brain Lord just like that?

The gray robe and the beholder aberration dared not make any movements.

"Pa!" Li Yue drove the Brain Lord, spitting out the magic armor, like spitting out a few melon seeds.

"Oogway… what did you want?" Li Yue finally stopped being silent, telepathically conveying his thoughts to them.

"Sorry… we were acting under orders… Oogway… Oogway wanted to seize the authority of the library…" The gray robe and the beholder aberration couldn't argue, throwing down the bag of ritual materials, trying to clear their relationship as much as possible.

"Oh…" Li Yue floated around the two gladiators, "So what about now? What do you want to do?"

"Uh… we… disturbed the Brain Lord's rest… we deserve to die… we'll leave now…" The beholder aberration immediately apologized, its eyes darting around, but it couldn't see any way out.

"How can you leave?" Li Yue stopped in front of the beholder aberration.

"Can't… I?" The beholder saw more messy bones, teeth, and threads inside the brain through the cortex of the brain in front of it, and didn't even know which one to target for a desperate fight.

"You are my eye." Li Yue prepared to wrap up the beholder and slowly kill it until it dropped the "Aberrant Eye"—anyway, this guy has so many eyes on him, stabbing them one by one should increase the drop rate, right?

Of course, the main reason was that Li Yue wanted to vent his anger—the library that he had managed to arrange was broken through in the bloody corridor; Galareck, a usable talent that he had finally subdued, was torn apart by them so that not even the corpse could be found?

"Do you want the arena to fully attack the library?" Seeing that Li Yue hadn't made a move, the gray robe thought there was still a possibility of negotiation, "Let, let me go back, I will report what I have seen to the master, and quell our conflict…"

And Li Yue's conversation with them was actually just enriching the Demon Illustrated Handbook.

"No, you won't. You'll just bring more idiots and attack the library even harder, just like Bodekoli." Li Yue still remembered the resentful emotions and malice of the "Slaver" at parting.

Other things were hard to say, but Li Yue also used the brain's memory on "holding grudges," and was quite talented at it.

As Li Yue spoke, the tentacles moved in unison, first petrifying the gray robe, then twisting it into a pile of mud.

"I'll fight you!" The beholder aberration knew its days were numbered, and finally mustered the courage to resist, and then suddenly found that it was dark.

Li Yue wrapped the beholder aberration with tentacles, covering all the eyes; between the gaps of the tentacles, bone swords or bone spurs were constantly inserted, piercing the aberration's eyeballs one by one.

The tentacles began to be stained with various colors, which was the beholder aberration's feeble resistance; Li Yue mechanically stabbed like this, and before the Demon Illustrated Handbook could prompt him, he suddenly found a skull falling out of the Brain Lord's brain grooves.

"Master?"

"Are you helping me get revenge?"

"Or are you playing?"

Galareck gathered a few pieces of broken bone, trying to create a clattering sound.
