I'm a monster in Demon King's Castle

Among the three demonic relics, the Flying Dagger had the simplest and most obvious function, and Li Yue found its location immediately—on the door lintel of the library.

Just as Freina had demonstrated in the Forbidden Forest and the Colosseum, a demon who wielded the dagger could gain the ability to fly, release extremely cold air, and create extremely cold barriers.

As for the negative effects of this demonic relic… it only occasionally released ice pillars, which wasn't too bad at the door lintel height, as it wouldn't hurt the Mini Minis, and the Brain Spirits could dodge in time.

Placing it on the door lintel would not only make it convenient for the library's demons to use at any time, but it would also directly deter some lost creatures, stopping flies or bugs—after all, many Mini Minis had complained about too many bookworms in the library, which not only ate books but also often went to the warehouse to steal food.

Moreover, the current defensive works of the library mainly relied on physical damage such as Demon Wolf Fangs, Bone Spurs, and Thick Earth, adding some magical damage like cold air… would be more balanced.

Li Yue also found a temporary job for Galarick, who had come to join him—guarding the gate. So this Flying Dagger… basically belonged to Galarick, while the Brain Spirits and Mini Minis could use it as needed.

As for the bones that had been shattered by Oogway Boogie, Li Yue was trying to use the "Self-Healing Bone" to repair them, on the one hand, to re-endow Galarick with a skeleton, and on the other hand, to indirectly control the Skeleton Knight.

With just a thought, if Li Yue wanted Galarick to dance, he couldn't ride a horse.

Of course, the Self-Healing Bone itself was also built on Galarick's remaining body, additionally supplementing the bone matter that had been gnawed away by flies and insects, so Galarick could still move freely.

Being able to obtain the bone matter of "Skorzy", Galarick only felt supreme glory. Now, the only regret he still had was the issue of his mount.

Li Yue didn't have time to care about what he wanted to ride. Anyway, with the Flying Dagger, Galarick could fly, so the mount could be resolved later.

Having found a home for the Flying Dagger, Li Yue began to study the "mutated" skin of the Freak, and called on Yingying to join him—after all, the Freak Puzzle was a simulation battle reward from the Shadow Demon. Li Yue was even willing to give Yingying the Lamont Relic, so naturally, he wouldn't swallow it.

Anyway, they were all his own demons.

"What's different?" Li Yue telepathically asked Yingying while letting her carefully sense the changes in the Freak Puzzle, hoping that this demonic relic could meet his requirements.

Having not found a suitable skin, Li Yue could only appear as "Skorzy" most of the time. Now that the "uninhibited bony trendy man" had already made an appearance in the Colosseum, it was no longer suitable for concealing his identity.

If the Freak's skin could really hide things under the skin and change its shape, as Masna had shown, it would undoubtedly solve the two major issues of concealing identity and hiding things, and could become a second layer of buffer "between Transfiguration and Demonic Blueprint creations", creating more surprises.

Moreover, Li Yue had also discovered in battle that this skin had good resistance to petrification, electric shock, and other effects—if this skin was draped on the outside, it could even enhance the protection of his own Brain Spirit body!

It was a must!

These thoughts of Li Yue surged towards Yingying's consciousness like waves, making Yingying suddenly feel that her existence had become sacred—the Lord of the Library was praying… this was the powerful demon's obsession with becoming stronger…

Waiting anxiously, Yingying gave the answer: "Just like you thought, it can squirm into the skin you want and store the things you want to store inside…"

Yingying talked about the changes of this demonic relic, which were similar to what Li Yue had sensed. It was worth mentioning that the skin could be split into a maximum of eight parts, and its strength would also decrease depending on the number of splits…

One person playing a whole show? Li Yue had already imagined eight skeletons wearing eight skins, with eight clones performing Snow White.

But soon, Yingying then mentioned the negative effects of this demonic relic, which were also related to splitting—the human skin worn by Mandena added more "living" characteristics to the Freak Puzzle. The more times it was split, the greater the influence of the Freak Puzzle in this demonic relic, and it would eventually become eight Freak individuals, no longer able to be worn.

Of course, Li Yue couldn't allow this situation to occur, thinking that one piece was enough, at least the strength could always be maximized. Even if it became Isaac's grandson… no demon would see through it, right?

Anyway, that guy was originally very durable.

"Then… this demonic relic…" Li Yue stammered telepathically to Yingying.

"It's yours." Yingying was very generous, taking out the Lamont Relic from the Shadow Space and playing with it.

Li Yue was also not polite, stuffing this mass of human skin into his chest cavity, and then placing the Staff of Deception in front of him—the treasure of the Jackalwere family, a demonic relic that Oogway Boogie wanted to possess, was now about to bloom with light and heat in the library.

"Friend, hit me with it." Egghead called for Galarick to hammer him, but the Skeleton Knight ignored him.

With a touch of his mind, Li Yue understood the function of the Staff of Deception.

It was very simple, it was "deception", deceiving perception, deceiving reality… and could even hide one's own thoughts to a certain extent, like Mandena's slow half-beat.

The application was extremely wide, but Li Yue knew after a slight sense that he couldn't exert the limit of this staff for the time being—as soon as he had the thought of casting a spell, Li Yue felt that all his magic power had been sucked away, and if it weren't for the library's authority providing magic power supply, Li Yue would have almost been sucked into a brain stem.

And the magic consumption of deception was also proportional to its effect—for example, swapping a corner of the Forbidden Forest with the Colosseum, or deceiving Oogway Boogie, making him believe that the Jackalwere family had not taken action…

These all required a huge amount of magic power consumption, which also prevented Mandena from completing the "deception of Death" quickly at the end, and Li Yue used the Skeleton King's vacant authority to pull him back, killing him under the Thorns of Decay.

"I can't use it." Although Yingying had abundant magic power, she could only admit that she couldn't do it when she saw the Staff of Deception.

Egghead couldn't either—its main function now was to be beaten, and it hadn't quite figured out how to use magic power yet.

"It doesn't matter, as long as we find the right way to use it, it can still play a big role…" Li Yue could call upon all the magic power of the library, so he could naturally use the Staff of Deception to a certain extent.

It was just that… the content of the deception needed to be carefully considered. Although it couldn't be taken outside the library for use, it was enough to use it temporarily inside.

Li Yue decided to carry out different degrees of deception against different intruders.

For example, creating some illusions, or making intruders get lost, or using the Staff of Deception to lure enemies to the Bone Room reception room…

Damn, if he had Mandena's level of control, Li Yue could even "deceive" space, using this staff to go to the place he wanted to go?

Go to the vault? Go to the throne room?

Li Yue also admitted that he was thinking a bit too much—how could Mandena not have thought of it? Obviously, his strength was insufficient to reach these high-level places.

However, with the magic power support of the library, there were many ways to use the Staff of Deception. As long as he grasped the mindset of the intruders, he could play however he wanted…

When the time came, he would "deceive" himself with a layer of skin, transform with a layer of skin, add a layer of skin from the Freak Puzzle, and a layer of skeleton… who the hell could know that the one holding the power of the library… was a Brain Spirit from the Fifth Library?

Li Yue was overjoyed. Although he couldn't "normalize" these deceptions, it was better than being ever-changing, greatly enriching the possibilities of the library.

He could just verify it in the storm the night after tomorrow, proving that the library was already a very terrifying area…

Li Yue took the Staff of Deception back to the upper level of the library, while adjusting the Freak Puzzle to make new skin, and waiting for Mai Mai to return with his profits.

But before Li Yue waited for Mai Mai, he first waited for Piggy and Lulu Feifei, who had gone to the Colosseum to eat limited-edition ice cream—the left and right guardians of the library came back fully loaded with a pig and a small cart of ice cream.

Seeing Galarick guarding the door, the two little guys snatched two of his ribs, dipped them in ice cream, and shouted that it was delicious; Piggy was also interested when he heard this, moving all six hands and pouncing on the Skeleton Knight.

Li Yue had a flash of inspiration and "deceived" Galarick into Skorzy, playing with the little guys.
