I'm a monster in Demon King's Castle

"Did I just mutate?" Copper Spoon looked at his two bare, severed hands, feeling a throbbing pain. "How strange, why? I didn't even feel it..."

Li Yue almost lost the chief engineer of the Library, feeling lingering fear. He continued to hold Copper Spoon's shadow in place, afraid that the guy's head would swell up again.

Egg was busy forcing Copper Spoon to heal, watching with interest as the dwarf's severed hands slowly grew back.

"What are these?" Having just grown back a few bones and bits of flesh, Copper Spoon couldn't wait to point to the Icefire Wheel and Demon Ribbon displayed before him.

With Copper Spoon's craftsman's eye, he could naturally see the potential of these two materials—just the Icefire Wheel alone could become a new ammunition element for bone bullets, expanding the types of ammunition...

And the simplest thing was that if the elemental damage of ice and fire could be resolved, it could be directly used to replace the wheels of the Copper-0 tank, flattening all obstacles on the road.

The Demon Ribbon, being light and飘飘, could obviously be used in some way to wrap around various creations, offsetting some of the weight brought by the high-density self-healing bone belt.

Copper Spoon didn't yet know that Li Yue had completed the soaking, and from now on, he could directly produce materials with the "lightweight" effect already applied from the Demon Encyclopedia template.

Li Yue quickly explained the uses of the two materials to Copper Spoon, and the chief engineer of the Library was already itching to get started, perhaps because his hands were growing back.

"Besides these two, I also brought you some upgraded parts for the steam machine soldiers and clockwork warriors..." Li Yue said, dumping various scattered parts from the shadow space, spreading them out in front of Copper Spoon. "See if there's anything you can use, or anything you can't reference."

Copper Spoon occasionally pointed out a few things. The steam machine soldiers and clockwork warriors were also lying flat on the ground, being pieced together into a silhouette.

"But the Icefire cannonballs are still needed!" Copper Spoon instructed, "If we don't enrich the types of cannonballs, our elemental strikes will regress."

"In the near future, the Tass Empire will attack Demon King City," Li Yue wrote.

After all, there's no telling when Yi He will arrive at Demon King City. The Library needs practical and readily available responses.

"What he should be considering is... how to either draw Yi He into the Library, or make me notice the Library," Copper Spoon said, getting to the heart of the matter.

"Hmm..." Copper Spoon nodded slightly, pondered for a moment, and then grabbed Da Harry by the collar with his bone hand. "The Tass Empire's air force has a lot of potential. You need to quickly find a way to eliminate us..."

"Hmm... You should learn to target one of the elements he uses and set up some defensive strategies, like the simplest being to hang up a bunch of tentacles." Copper Spoon thought for a moment and said, "But if you only defend against elemental regression, there are also ways to break through. If what he uses is truly a small magic guide, then at that level, he won't care too much about the interaction and restraint of elements, etc..."

Copper Spoon dragged Da Harry away from the reception room. Li Yue recalled the recent "mutation" and still felt lingering fear.

At this time, the banquet had just begun, guests were entering, and the Tass Empire had served another appetizer.

"What are you planning to do?" Yingying knew it was time to sort out the Library's future—the approaching Imperial army, the Library's inexplicable knowledge, the Oogey Boogey hidden in the shadows...

【What are you looking at? It has nothing to do with you?】

"Yes, it is it." Li Yue wrapped up the two Demon Sons and left.

Copper Spoon listened and watched quietly.

"By the way, humans are about to attack. What do you think?" Fang Ying asked about the craftsman apprentice's feelings.

"That's also the seventh thing I wanted to say..." Li Yue told Copper Spoon about Yi He's abilities, and also asked Egg to transmit the scenes of the two encounters with Yi He to the dwarf.

Deceiving Yi He also requires a massive amount of magic power and cannot cope with certain crises, but it will be the norm.

"Later, I will give you a new list of parts. The existence of the ribbon and the Icefire Wheel will, of course, require a completely new upgrade to Brain-0, Bone-0, Evil-0, Copper-0, Rice-0, and the bone bullets and bone-guided cannons. In the later stage, of course, Li Yue needs to provide support with templates other than the Demon Encyclopedia.

"Is there any way to deal with that kind of element and elemental combination magic... to ensure the absolute safety of the Library?" Li Yue wanted to hear what suggestions the chief engineer had when facing the ninth-order elemental mage, Yi He.

Seeing "Tass Empire," Da Harry didn't seem to have any reaction—during those days staying in the Library, the newspaper boy had already learned some basic Demon Common Language.

"No, it's not a prophecy, it's my guess, but it will inevitably happen." Although Li Yue didn't have the ability of the Fire Burning Valley prophet, some big shots, including the Demon Kings, were busy digesting the flesh and blood of the Heavenly Spine, and no demons could stop Yi He and the Tass Empire's military might, so the Tass Empire attacking Demon King City was only a matter of time.

"Do they also fly with propellers?" Copper Spoon asked about Imperial technology. Fang Ying immediately asked Egg to transmit the scenes seen in the Holy City ruins to the dwarf.

"I'm leaving! Take your time!" Copper Spoon pulled Da Harry up again.

"Is there anything like... aircraft wreckage?" Copper Spoon looked at the parts laid out on the ground and raised his head to ask Li Yue.

"Okay, let's do that." Li Yue realized that all he could do now was this.

Li Yue didn't expect Harry to act so quickly, it seemed that Copper Spoon was quite satisfied with this craftsman apprentice.

"When the time comes, we can test-fire the bone-guided cannons, so you can make a little more first." Li Yue used his shadow to place a group of bone-guided cannons on the ground, "Anyway, they don't need to be lightened, and they don't need to be fitted with Icefire Wheels."

"Ah? A prophecy?" Copper Spoon frowned.

"Take it easy, take it easy, it's just a pair of hands, it's not a big deal to heal. I've long disliked them and wanted to replace them with a new pair." Copper Spoon raised his bone hands, seemingly preparing to give them a small modification before they grew flesh.

"It doesn't matter... I'm very happy here." Da Harry's Demon language was still very rusty, with many ungrammatical errors, "If possible, if the Imperial army comes, please... let me fire the first shot."

Li Yue agreed with Copper Spoon's view—if he could annex the Colosseum and be promoted to a major pillar, the Library would have more magic power and it would be much easier to deal with.

【Oogey Boogey?】

"As for the kind of destruction magic you just showed me... I will set up a layer of bone walls and tentacles on the inside of the Library, which should have a certain defensive effect."

"No." Li Yue hadn't encountered any plane crashes on the way back, presumably because the defeated expeditionary force was only a scattered unit and not worth the Empire mobilizing its air force.

Li Yue felt that taking the Library out of Demon King City... should be more difficult than confronting Yi He head-on.

"I know what to do..." Fang Ying had already thought out the next step, "After everything is over, we have to find that guy first..."

"You also hurry up and find a place. I want to test-fire the tanks and bone-guided cannons to verify their effectiveness..."

Copper Spoon felt the pressure brought by the competition, silently examining the parts all over the ground, and suddenly plugged the pituitary gland into the bone wall: "Harry? Come here!"

"Wait a minute, don't rush. I have some news to tell you." Li Yue used his shadow to separate Harry and Copper Spoon, "And also help him heal his bone hands first, otherwise he won't be able to work well..."

Not long after, Da Harry, as Copper Spoon's apprentice, ran into the Library with his head lowered. He didn't greet the eight Demon Sons, but directly started piecing together the parts on the ground like assembling toys, as Copper Spoon had said.

Copper Spoon had never been clear about creations and didn't value human technology. Li Yue also told the dwarf about the Tass Empire having developed airplanes.

It was estimated that when Yi He arrived outside Demon King City, he would see the Empire's air force again.

But this was not something that could be done very quickly.

"The foundation of everything is 'strength'." Copper Spoon concluded, "If strength is not enough to stop Yi He, everything is in vain, and in the end, you will die."

"Or simply, let's escape." Copper Spoon scratched his beard with his bone hand, "Anyway, his target is Demon King City, not the Library."

Egg asked.
