I'm a monster in Demon King's Castle

An operation targeting the Brain Spirit Lord, Budi Bogg, was underway, but Li Yue in the library was completely unaware—first, the sensory objects needed constant soaking, leaving no time to be distracted; second, all the Abada demons' actions were aimed at Budi Bogg, and since they couldn't find the brain's location, there was naturally no movement for the time being.

Returning to Li Yue, the soaking progress was being rapidly accelerated. By the time the green hour arrived, the binding thread, the magic wolf's tooth, and the lava right hand had all become new sensory objects, leaving only the mutated eye and the octopus tentacle not fully soaked.

Li Yue thought that it might be because these two materials were somewhat related to demon relics, so they took longer to soak?

After these three materials became sensory objects, whether it was the sharp, bony handsome man or the rebellious, bony trendy man, they could move like ghosts in the bone chamber reception room, with extreme speed, and even slapped Dandan's eggshell…

There was a white bone handprint on the eggshell.

"Huh? What's going on? Again, again!" Dandan was in pain from the slap, not expecting Li Yue's palm to deliver such power.

Li Yue dispersed the particles surrounding the bone hand. Although the self-healing bone and lava right hand inside were crushed, that one blow had fully verified that with the increase in sensory objects, the overall strength of each template had greatly improved, even enough to crush iron walls.

After testing the movements, Li Yue casually threw out that "sharp, bony handsome man" and tested the superimposed effects—the binding thread used to bind and sew different materials or objects together, which undoubtedly required piercing. But after becoming a sensory object, the thread ends could directly connect to the target, eliminating the "piercing" step.

Although this was an inconspicuous change, only Li Yue knew how useful "superimposition" would be on this basis—from now on, not only could the material between various substances be ignored when planning templates, but the binding thread could even become a "spider silk"-like existence, directly acting on external objects for adhesion and splicing!

To some extent, it not only became Li Yue's own fascia but even occupied part of the "tentacle's" work… If the book demon that was casually killed in the beginning knew that it would occupy such an important position in the library in the future, it would definitely be surprised.

Under the connection of the binding thread, countless thin threads first adhered between the two "sharp, bony handsome men," and then Li Yue used the library's magic power to "superimpose" a trace of sewing effect on the binding thread, and the two skeletons were seen merging together, face to face, bone to bone, forcibly merging into one!

The density doubled, intertwined with each other.

This was the effect of the binding thread sensory object and the "superimposition" effect—Li Yue also, to some extent… possessed the ability to "sew," making it more convenient to create traps and items, and no longer needing to be too concerned about the structure.

After Li Yue studied the binding thread almost thoroughly, Li Yue turned his attention to the "magic wolf's tooth," and was disappointed to find that this material did not have any superimposition effect. After becoming a sensory object, it was only more convenient to control.

For example, Li Yue could now bite a piece of self-healing bone, keeping his upper and lower jaws still, completely letting the magic wolf's tooth complete the chewing and grinding, which looked very cartoonish.

During the trial process, Li Yue couldn't help but imagine that if he used his thoughts, or combined it with certain mechanisms, the magic wolf's tooth would not only be a tooth, but a meat grinder-like existence, used to enhance the destructive power of the bloody corridor.

Finally, there was the lava right hand that Li Yue was doubly looking forward to.

At the sensory object level, the lava right hand was similar to before, able to splash lava with Li Yue's telekinesis, and could also shoot out, playing some movements similar to flying fists or fission, but after slightly trying "superimposition," Li Yue was disappointed to find that the lava right hand did not have any superimposition effect, and could not give substances "heat."

Not only the lava right hand, but most of the remaining materials did not have "superimposition" effects, only the octopus tentacle, after fusion with photon pigments, had a little change—in addition to being able to change color according to the environment, it could also vaguely give items some "color-changing" effects when superimposed, but the remaining magic power in the library was insufficient for Li Yue to further experiment. These two things were also completely bound together, becoming a "color-changing octopus tentacle" in the demon illustration list.

Finally, after looking at the sensory object state and "superimposition" content of all the materials, Li Yue suddenly fell silent, gathering his thoughts on the magic guide motorcycle and the magic guide cannon. The knowledge in his mind rolled, and the Demon King City, which was originally laid out in the shape of the Chaos Continent… suddenly lit up slightly, being re-outlined by Li Yue.

The outlined range was limited to the library of the Demon King City, and the outlining process seemed to have pauses, constantly appearing one problem after another. Li Yue, combining all the knowledge accumulated in his mind, suddenly seemed to be possessed, smashing those light spots one by one, and drawing wildly in the bone chamber reception room.

In the future vision of the library outlined by Li Yue, the Spader particles scattered to various nodes of the library became bone-like existences. These particles extended into metal, bone, and binding thread veins, and then extended to every corner of the library room, rock cave, and bone chamber, finally "pinching" the entire library into a whole!

"A city within a city…" Yingying looked at the picture drawn by Li Yue and directly understood Li Yue's thoughts—this guy was preparing to treat the library as another castle within the Demon King City.

A castle with an independent power system, magic power cycle, and defense power!

Self-healing bones, Spader particles, alloys, and soil as bones, binding threads and octopus tentacles as blood veins, the power system of the magic guide motorcycle as the heart, the firing device of the magic guide cannon as claws… Li Yue was going to build a territory that absolutely belonged to the brain spirits!

Although many details relied on imagination, and the overcoming of many difficulties only relied on Li Yue's rough adhesion, the overall idea was already quite hideous, allowing Yingying and Dandan to see completely new possibilities.

This brain spirit's idea is really bold… He actually wants to make the library… independent?

Dandan and Yingying looked at the painting, silent.

Of course, it was impossible for Li Yue to forever depend on the Demon King City for existence, and if he wanted to compete with other Lords of Authority, every inch of the library's land had to be used and become a deadly weapon.

In fact, to put it bluntly, the main problems were only three—power, materials, and design.

As for power… it was difficult to completely rely on the heat provided by the lava, so he could only find a substitute other than magic power—this point could not be solved by finding a solution through a single "promotion," so he could only continue to search in the Demon King City in the future, looking for a way to make a library-exclusive "power furnace."

The remaining two problems were a little simpler, such as materials.

Materials included not only the metal materials needed to copy and enlarge the power furnace itself, but also the materials to enhance the overall structure and defense performance of the library, as well as the materials to arm the library with magic guide cannons… With so much material demand, relying solely on Dandan's particles was obviously not enough.

Fortunately, after the particles became Li Yue's sensory object, the speed of analyzing other metal materials also accelerated, and Li Yue translated the second material problem into a new demand, a hunting demand.

That was… to search the Demon King City to find a demon that could drop usable materials and include it in the demon illustration.

In this way, Li Yue could exchange through malice, increasing the quantity and quality, and also help the library achieve this complete upgrade.

The third point, which was the last core issue, was design. This required technology-oriented talents, and endless trial and error space and time.

Li Yue could barely put forward some design concepts, but the specific production and experimental demonstration… could not be done by a single brain spirit—Li Yue already knew that some dwarves were very good at these mechanisms and the like, and the dwarves' magic guide mechanics had always been able to compete with humans, and it seemed that the Tas Empire had also borrowed a lot.

But where to find dwarves? Dwarves also have many tribes. What if the ones found are martial tribes and not technology-oriented…

Currently, Li Yue didn't have any real technology-oriented talents around him, so he could only temporarily rely on the brain spirits and Mini Minis to help, and even do it himself; as for the trial and error space, it must be solved through the collection of malice, investing a lot of materials, enough for the little guys to not eat or drink, and then using massive materials and experiments to turn the design into reality.

What new things could brain spirits and Mini Minis make together?

Li Yue was quite looking forward to it, and casually filled the bone chamber with books related to future construction, such as "Deadly Mechanisms" and "Heat Thermodynamics," written in the demon common language, to facilitate the brain spirits and Mini Minis to study.

As for Li Yue himself… of course, he also had a brand new set of skin ideas after this "promotion."

Whether it was for construction or for killing… both hands had to be hard.
