I'm a monster in Demon King's Castle

“Ah, eee! Itchy, itchy…” Mini was giggling, holding the cable that constantly released electric sparks, under the influence of “Self-Healing.”

“You… you aren’t afraid of electricity?” Leylin was stunned—not only was she like a rubber person when fighting and working, but even her texture was similar?

Also, because of this delay, the left and right guardians of the library heard Leylin's thoughts and scurried over.

Seeing Mini giggling while holding something they had never seen before, and Leylin staring blankly at her, Lulu felt that perhaps her companion had caused trouble, and hurriedly pulled the little one behind her, poking her fingers nervously.

“Brother, what happened?” While Lulu was asking, a group of potato heads gathered at the iron gate of the upper cave entrance, watching the excitement together.

I have to remember to close the iron gate on the upper level of the library in the future…

Thinking like this, Leylin first used his mind to close the iron gate, then withdrew the simple cable he had just made, and looked at the left and right guardians, still a little speechless.

Mini and Mini were actually full of treasures, which Leylin had not expected—if he were a real demon, he would have peeled off their skins to make cables, right?

It could also be considered a way to support the construction of the library in another way.

But Leylin was different.

Lulu reached out and brought a large cushion and several pieces of stored Self-Healing Bone from the darkness of the lower cave—this was all you and Leylin had in the library; the rest had been eaten.

The scene of Feifei Minis wailing and peeling each other's skin was deeply imprinted in Donghui's mind.

“Is the switch ready to break?!” A kingly electric horn hung on the wall of the Bone Chamber reception room. Lulu shouted at a Feifei Mini below the Bloody Corridor.

“Will it hurt a lot?” Since Lulu had clearly stated her position, Mini would certainly not be polite with us, but still felt a little heartache.

The eight hundred skeleton soldiers were arranged by me in an orderly manner, yet extremely uncultured. They usually ignored any strange things that happened in the library, like a majestic background wall; only when a hero arrived would they step out of the background and chop the hero into mincemeat.

“You… continue to wait!” Lulu waved her hand, and the Feifei Minis and Brain Spirits at the inner door of the Bone Chamber reception room watched together, casting their gazes towards the main entrance.

Mini, together with Galarick and seventy skeleton soldiers, stood on the inner side of the Bone Chamber reception room, anxiously anticipating the performance of the electric tower.

Holding the cable in one hand and entwining Leylin with the other, Lulu swung the cable over Leylin from head to toe, crackling, but without causing any harm.

“Well, it’s not finished yet.” The Feifei Mini was at a dangerous distance, and Mini had not suppressed the lightning pool. At this moment, his back was covered with menacing lightning.

“What about you! Old thing, are you ready?!” Lulu greeted the old Horned Demon in the center of the Bone Chamber reception room—this was not the first combination of the old Horned Demon and the discharge device, but also the first attempt to test the power of the electric arc.

“Fortunately, you are gifted, otherwise this little thing would have been electrocuted.” Clearing up his mood, Donghui comforted the Feifei Mini, floated over and touched the little ones' heads with his tentacles, canceling the Self-Healing buff.

Donghui certainly couldn't bear to see these things, and wanted to stop the plan several times, but Lulu and the other Donghui Minis shouted and scolded, forcibly pushing it forward.

“Ready!” In that Donghui Mini's hand, he held the most luxurious bone switch, which was actually just using the Feifei Mini's skin to block the current, and turning it on to conduct electricity, without even controlling the voltage.

The only volunteers who offered their skin were Lulu and Leylin, but soon, all the Feifei Minis were inspired by the left and right guardians and voluntarily joined this grand action.

“Here it comes! The hero is here!” Budibog suddenly appeared from the library's main door, his back shining with holy light.

“Good! I announce! The first power-on test firing of the library's electric tower officially begins!” Lulu's mouth stretched wide.

And Lulu's rhetorical question made Mini also recall the scythe that had scraped his head when he had just crossed over.

He didn't expect that the little ones would use this thing to choke him.

Without the enhancement of "Self-Healing," it would be possible to avoid killing the chicken to get the eggs, and to pry it from the Mini Minis intact.

“Why not? Brother, you can heal injuries, then you can peel off our skins to make cables, and then heal us.” Lulu's intelligence has also been greatly developed. Without much thought, she found a feasible method.

This also made Donghui even more admire Galarick's leadership skills.

During this period, Mini, of course, worked day and night to strengthen the Self-Healing of the Feifei Minis in the library room, almost consuming all the magic power allocated to the library every day; Galarick also put the eight hundred skeleton soldiers into the daily management of the library, assigning patrol and emergency response groups, and constantly imparting skills to the Feifei Minis who loved swordsmanship and fighting.

Amidst a chorus of wails, the Feifei Minis completed their contribution to the library.

Even if it really is a very good plan…

“Brother goes to the arena to fight, to avenge the red-skinned demons for us, doesn’t it hurt?” Lulu stiffened her neck.

It was just too cruel. As soon as Leylin saw the pitiful appearance of the three little ones in front of him, he silently denied the plan in his heart.

And the old Horned Demon brought from the Forbidden Forest had long since recovered his vitality. After signing a soul contract with Mini, he completely obeyed orders and became one of Mini's important experimental subjects.

“You can’t.” Mini shook his head and pulled back the cable.

“Alright.” Having said what needed to be said, Mini couldn't forcibly stop the Feifei Minis from contributing to the library. Moreover, the value of an electrical system was unparalleled, and it was the top priority for the library's next step of development.

Lulu's heartfelt voice was extremely firm, and she even hated Leylin along with it. Mini was both amused and annoyed.

“We can.”

But the skin of the Feifei Minis was limited, and Mini's time was also limited, so he had not yet replaced the eight hundred skeleton soldiers with Self-Healing Bones, nor had he separated the skin of the Feifei Minis and stuffed it into our soul lodgings to help us control the Horned Demons—these two things were not urgent, and the eight hundred skeleton soldiers were already strong enough.

…

Seeing that Mini was still shaking his head, Lulu got angry on the spot: “We've already said it, let us help the library. Brother, if you don't need us, then we might as well go back to our hometown. We'll leave right now.”

Mini spent eight days cutting skin from the Donghui Minis to make cables, finally completing the laying from the lightning pool in the lower cave to each room, and even didn't have time to go to the arena to search for the Kingston family's relic left there by Jesse—the magic mirror.

The little one who mistakenly took the cable was watching from the side, completely unaware that the little hand that was stretched out for fun would cause such a big change and a qualitative leap in the library.

“Brother, are you making cables?” Lulu saw that Mini didn't react, observed for a long time, and also saw what Mini was going to do—early on, it was you and Mini who translated the library's books about "textile workers," and had a certain understanding of human industry; recently, she had listened to the blond Tom a little more, noticed the lightning pool constantly discharging behind Donghui, and immediately understood.

“We can.” Lulu repeated, her eyes blinking fiercely at Mini.

【Really leaving, not staying, brother doesn't need us… If he dares not follow me, I will never let him touch me…】

After completing the laying of the cables, Mini chose to test the results today.

Among them… of course, there were also heroes who strayed into the library.

He also recalled the scorching cold death intent when the Purgatory Heart exploded.

Also, in the days before the Demon Expeditionary Force set off, some heroes began to appear sporadically in Demon King City, rushing to the throne room without regard for their own safety.

“Brother, you need insulation.” Lulu was not confused by Mini's actions, stretched out her arm, grabbed the simple cable that was still releasing electric sparks, and shook it.
