I'm a monster in Demon King's Castle

Just as Li Yue took advantage of the Brain Spirit Master going to the Slaughter Cup and blew up his home with the Heart of Purgatory, didn't the other demons think of that?

If you want to invade the library, what better time than when the Brain Spirit Master is participating in the Slaughter Cup?

Even if the Brain Spirit Master has the Demon Child to help, today is the full moon, the graduation class of the closed warfare training, how could there be a Demon Child guarding the library?

Having figured this out, Li Yue even guessed where tonight's crisis came from—wasn't it Oogie Boogie? This burlap sack demon... probably had this idea when he forced Boody Borg to participate in the Slaughter Cup.

This way, even if Boody Borg survives in the finals, his home will be stolen.

His demon cocoon... no wonder Oogie Boogie had to snatch the Staff of Deception—with the magic nourishment of the arena, plus the authority of the library, even the City Lord of Deception might be...

Li Yue suddenly stood up, murderous.

"Hehe... there should already be gladiators fighting at your doorstep, right?" Mento raised his hand to let him pass.

"By the way, one last question." Before leaving, Li Yue turned and asked, "Which pillar of the Demon King City are you, which authority?"

Li Yue looked at the worms on Mento's chin, always suspecting that this Demon King tutor was inseparable from the Abyss Maw.

"My authority is not here, not in this world." Mento smiled, signaling Li Yue not to guess, and to get lost quickly.

Li Yue looked at Yingying and Dandan, who were freezing in place, and didn't delay their graduation class. He turned and ran back to the Gate of Chaos—no matter what rank the gladiators who came were, Li Yue would turn them into minced meat.

Seeing Li Yue fly away, Mento stroked the worms on his chin and conjured three other cards out of thin air—each card still had worms on it, one invisible, one wearing a mortarboard, and one holding a small hammer to repair things.

After thinking about it, Mento pulled out the one with the mortarboard and stuffed it into Dandan's eggshell.

...

When Li Yue returned to the library, Garralick, who guarded the gate, had already been beaten into a pile of broken bones and debris, almost to the point of having his ashes scattered. It was just unknown whether the soul's lodging place had been damaged.

Garralick also fulfilled his duty as a gatekeeper—even if he was smashed to pieces, he still blocked the invaders' footsteps, which made Li Yue feel silent for a while.

The bloody corridor on the first floor had also been activated by the Mini Minis, and at this moment, it was tightly pressing down on the corpses of three gladiators, allowing the blood they continuously left behind... to nourish the land of the library.

Among the three corpses, one had both hands firmly grasping a Flying Dagger, even frozen into a blood clot, still wanting to stuff this demonic relic into his pocket.

Outside the gate of the library, there were four other gladiators busy—they were carrying a large bag of ritual materials, wanting to dig a tunnel in the closed bloody corridor, leading to the upper level, to carry out the ritual of stealing authority.

And beside them, there was naturally a group of flies surrounding them, constantly posing the word "death" in the common language of demons, urging them to hurry up.

Two of the four gladiators were digging, their hands covered in blood and pus, constantly complaining—the soil layer was full of bone spurs and demon wolf teeth, and digging a little would cut them open, causing a "bleeding" effect, greatly slowing down their actions.

And the remaining two gladiators didn't help, each watching from behind, as if they weren't suitable for this kind of heavy work—there were a total of seven gladiators invading, each with a strange appearance. Li Yue didn't know their ranking, but combining their appearance and analyzing the experience of demons, Li Yue could roughly see what tasks they were shouldering.

The three who died in the bloody corridor were all combat types, and now they had been smashed into minced meat, so naturally there was no need to say more; among the remaining four, two were combat types, and the two digging were wearing demon armor, probably similar to "Patrolling Sword" Paladin, both humans who had fallen into the arena, and their status was relatively low, suitable for heavy work like digging.

But even with the protection of the demon armor, the demon wolf teeth in the soil layer still caused them a lot of trouble, and the speed was not fast.

The remaining two gladiators were more special. One was wearing a robe, guarding the large bag of ritual materials, obviously preparing a complete set of rituals to usurp authority, waiting to go to the upper level to implement it—the bag even contained the flesh and blood that Boody Borg had been torn off in the first match of the Slaughter Cup, and the ritual materials were complete.

The gladiator at the very end was a beholder inlaid with countless eyeballs, looking impatient: "Hey, can you guys do it or not? Lord Oogie Boogie called me here to remove Boody Borg's imaginings, but you guys are so slow, when can we go back? There are still many female demons waiting for me to help them examine their bodies..."

"Say that again, how to remove..." The gray robe in charge of the ritual seemed more interested in this kind of thing, "I didn't understand before."

"You still won't understand if I say it again." The beholder had nothing to do anyway, so he didn't hesitate to explain, "The Brain Spirit Master has many imagined helpers. As long as they realize that they are imagined, their power will also be weakened. Understand?"

"No." The gray robe shook his head.

Li Yue was surprised by Oogie Boogie's preparation—not only had he prepared Boody Borg's corpse materials, but he had even come up with a countermeasure to solve the imaginings?

This guy must have coveted the library for more than a day.

"Bite my demon butt... but... the Brain Spirit Master actually prepared this kind of thing... was he prepared?" Urged by the fly swarm, the two demon armor knights switched to using swords to chop and axes to smash, and soon smashed the soil wall into flying debris, invading the middle section of the bloody corridor.

"Of course, after all, those who hold authority, who wouldn't be prepared?" The beholder's countless eyes rolled around, observing the situation in all directions, "The seven of us are the best choice for secret operations. Any more might attract unnecessary attention, and today is the final, the master doesn't have that many troops to spare for us... You guys work harder, don't shame Lord Oogie Boogie..."

The beholder seemed to be saying it to the fly swarm beside him.

"Yes, we have to be faster, before he dies or comes back, take the master to complete the ritual of authority transfer together..." The gray robe tightened his cloak, covering his ears and urging repeatedly.

The fly swarm flew around beside him, impatiently, seemingly about to drill into his ears if they couldn't see the progress.

Time was limited. After learning that the invaders were only these seven gladiators in front of him, Li Yue tried to analyze the strange beholder at the very back of the team as soon as possible—among the four surviving invaders, this beholder seemed to be the most special existence, and he needed to study it carefully before taking action.

So Li Yue analyzed and obtained the first demon with a "17" beginning—1797, the beholder aberration distributed in the "laboratory."

Its skills, in addition to the beholder's common X-ray vision and petrification ray, also included creating illusions, true vision... and its drop also had a resounding name—Eye of Aberration.

Come if you want, and bring a gift?

It just so happened that the eyeball didn't drop when killing the beholder Elana, and this time it can be made up for.

Just as the first-floor bloody corridor was about to be killed through by the two demon armor knights, encountering the slave scholars of the Sixth Library, Li Yue prepared to take action.

"Brother, what should we do? The instructor is dead." A large number of Mini Minis wearing bone armor gathered in the middle level of the library, Lulu's eyes were tearful, and she asked with a sword in her hand—at the first moment of the invaders' arrival, the Mini Minis and Brain Spirits were driven back to the middle level by the skeleton knights, facing the seven gladiators alone.

Not only the Mini Minis, but also the Brain Spirits were wandering beside, waiting for Li Yue to put on the "Slaughter Sea Butterfly" for them.

"I don't need you, I hate this kind of bastard who steals homes in the chaos the most, and actually stole to my head, I won't leave any of them... kill them all, to avenge Garralick." Li Yue prepared, and summoned the Brain Spirit Master's chariot that he had just finished making last night.

Then, Li Yue drove the library's authority to move the soil layer, recovered the Flying Dagger, and moved the bone room reception room to the end of the first-floor bloody corridor, choosing the battlefield.

The demon armor knights' eyes suddenly widened.
