I'm a monster in Demon King's Castle

"I was wrong."

Sensing Li Yue's anger, Shadow, like a child who had made a mistake, drooped its shadow and curled up at Li Yue's feet.

Li Yue was certain that Norell's suppression of it was still in effect—it seemed that the parent-child relationship was enough to suppress the crown.

This was a good thing.

"Knowing you were wrong is enough. Quick, take me to Tom and Copper Spoon," Li Yue ordered.

Shadow faithfully executed, instantly bringing Li Yue to the Great Hollow.

The dark environment was very desolate. Perhaps it was because the Slaughter Cup had taken away too many war-loving Underworld demons, but this side of the underground city was almost silent.

A huge mock library reconstruction was pulled into the center of the Great Hollow by binding threads. The outer walls and bone armor were not inlaid, the entire structure was hollow, similar in shape to the small model Li Yue had just received from Acheng.

The difference was that the small model of the library only had an outline, while the mock library was fully equipped, including the Thunder Pool and the Bloody Corridor, as well as bathhouses, warehouses, and so on, equivalent to all the structures of the library.

The Copper Clan dwarf's throne was placed in Copper Spoon's workshop, inside a huge petri dish—the petri dish was filled with blood, and a huge iron sphere hung above, filled with Copper Spoon's blood.

Li Yue ended his advancement.

"How is it?" Shadow solidified into Norell's appearance, swaying slightly as it walked behind the workbench, speaking according to Tom's instructions.

"Aggregation! As long as there's no aggregation, it can reach 87%! Or even less!" Yu Yi violently waved the illusory pages in her hand.

Waiting only for real materials to fill it.

Shadow slowly drilled back into Li Yue's body, controlling his shadow.

"Um… it should be Fourth Order now," Copper Spoon seemed quite eager to dissect Yu Yi's head to study its structure, to determine if he could pry out more designs.

Could it be the lifeline…

"Am I advancing?" Yu Yi wasn't too sure, asking through Shadow's mouth.

"Speak quickly, one at a time, what's going on?" Shadow was quite imposing.

Was this a coincidence?

The Sky Ark hadn't yet become Li Yue's new subject, and the sudden arrival of aggregation directly ended his advancement ceremony.

Copper Spoon sat, directing Big Harry to busy himself; Harry wielded his spine, trying to adjust a pillar to Copper Spoon's satisfaction.

Regardless of whether it was the Time Mark or Fate, Tom couldn't go against it, clearly having aggregation but not using it.

To break away from Demon King City, aggregation was necessary and had to be used.

Li Yue's head also became huge at that moment.

Obviously, Big Harry had even received an invitation to the Slaughter Cup, staying in the Great Hollow only to complete the tasks assigned by Copper Spoon and Norell.

Although his attitude was a bit arrogant, Tom didn't care too much—now that he wore the crown, which demon wouldn't have a bit of a temper?

Then there was no need to dwell on it.

Tom, of course, began to be suspicious.

Copper Spoon himself was inserted with various tubes, the tubes leading directly to the iron sphere, constantly nourishing the Dwarf Throne.

[This, you help… ]

With the concept completed, Li Yue forcefully propped up his huge head, sitting on the ground under the control of Shadow, his eyes vacant, staring straight at the Sky Ark.

And aggregation hadn't yet been applied to this concept. As long as it was filled with raw materials, it could be realized.

Immediately after, Tom remembered that the research lab was no longer sending knowledge to the library, what was sending knowledge was the Time Mark…

"Where are the materials I need? The materials? If the seventh test flight fails, I'll immediately find the reason and proceed with the eighth! The ninth! I need enough materials!" Copper Spoon tore off the tubes inserted into his body and rushed over.

The knowledge related to aggregation within the illusory pages rapidly expanded, occupying Li Yue's mind.

But his footsteps were faltering, rolling on the ground like a ball.

Tom didn't want the library's only scholar to become inexplicably distorted like that.

"Ha… what Order am I now, who knows?" Yu Yi's brain squeezed out a smile, almost laughing out loud, asking through Shadow's mouth.

Just feeling hungry, and someone's stuffing souls into your mouth?

Combining it with the fragmented sky he saw in the Slaughter Cup, Tom felt that it wasn't impossible that this was a gift from the Time Mark to the library?

Big Harry didn't speak, silently helping Copper Spoon, his palm stroking his spine—the spine lit up with a powerful candlelight.

"What method?" Tom didn't know what knowledge could suddenly increase it so much.

Yu Yi was puzzled—aggregation was something good that she had just discussed with Acheng through the Fate Dice not long ago, and before she had mentioned it for long, the library had more knowledge related to it?

"Is this angle right? Are you sure? I must be sure, this angle can withstand the pressure brought by the takeoff. We must calculate every bit of weight. I don't want the next test flight to fail again…"

"Did you hear that? If there's no way to get aggregation, we're far from success!" Li Yue really wanted to complete this project, and seeing that Shadow didn't respond, he urged repeatedly.

Every detail had text labels.

Copper Spoon, Li Yue, and Big Harry looked up together, and seeing that it was Shadow, they unleashed a torrent of output.

"By the way, what did you say just now? What materials do you need?" Tom turned to ask Copper Spoon.

"Alright, alright, give it to you, aggregation," Shadow waved his hand impatiently, took the small model from Tom's brain, and stuffed it into Li Yue's hand.

This time, Tom, Shadow, Copper Spoon, and Big Harry were stunned.

Beside them, Li Yue was constantly verifying the tall blueprints at the workbench, and also using illusory pages to simulate the various situations that the Sky Ark might encounter when it took off, ensuring that everything was covered.

And in addition to the initial design of the Sky Ark, the knowledge Li Yue revealed during this advancement even included several stages of the Sky Ark—from the initial start with only the library, to how the Forbidden Forest would be integrated, and then to radiating aggregation, absorbing the research lab into the library's authority…

These contents and designs were pasted as a whole onto the mock library in the center of the Great Hollow, marking the position, texture, and precautions for each part and material.

"Yes, I'm advancing." Shadow had the impression from Norell that the magic flow would change during advancement, and at this moment, the magic power in Li Yue's head matched this change.

"The seventh test flight is almost ready, the success rate should be around 36%," Li Yue said first, "But through the knowledge I recently obtained, I found a way to increase the success rate to 87%!"

Advancement complete, Yu Yi needs to rest.

A huge ship, based on the mock library and composed of illusory pages, was displayed in the Great Hollow, perfectly integrated and lifelike.

The illusory pages began to rustle.

"Why are you only coming now? Do you know how much knowledge has been added recently?" Scholar Li Yue unfolded the illusory pages with a rustle, the entire Great Hollow was almost filled, filled into the shape of blood vessels made of stacked books inside the library.

At the same time, massive amounts of illusory pages revolved around Li Yue, then gradually became transparent, turning into blueprints, and then virtualizing the outlines of the pages, leaving only the content and design.

"What do you mean? You want aggregation, don't you…?" Li Yue fiddled with the small model haphazardly, about to throw it away, and then suddenly fell into a daze.

After thinking for a moment, Tom came to the conclusion that—there was no way.
