I'm a monster in Demon King's Castle

The alarm bell of the Demon King's castle was very distinctive—it came from the flickering candle flames on the walls, constantly emitting an air of gaiety and joy as they swayed, as if something good was about to happen.

When the alarm sounded, Li Yue had just left the area where the vault was located and was still three corridors away from the main body's library. Then, Li Yue saw the bone piles in the corners of the walls tremble instantly, then assemble into one skeleton soldier after another…

They drew the knives and swords casually stuck in the cracks of the walls, ready to embark on a slaughter.

Li Yue, fearing that taking the Supreme Magic Stone had triggered a trap, cursed his misfortune and hurriedly stuffed the Supreme Magic Stone into his skull. He then subtly adjusted his transformed form, disguising himself as a nameless skeleton soldier who had just awakened from a corner.

"Hey? Where did you come from? Why are you sleeping here?" The skeleton behind him was very dissatisfied with Li Yue's position and squeezed him.

"Too much to drink, too much to drink… Wasn't it a carnival tonight… What happened…" Li Yue pointed to the wine stains on his chest and stood up straight, imitating the skeleton behind him.

"Wait, wait for instructions…" The skeleton behind him chattered his teeth—he wasn't very energetic after just waking up.

At this moment, Li Yue had already analyzed its weaknesses and body shape, ready to knock on its soul's dwelling place and replace it—in case the alarm was triggered because the tray skeleton's identity was exposed…

"Little ones! The carnival never ends! The vegetables from the vegetable garden have run out!" A skeleton riding a bone horse ran past Li Yue with a "clip-clop-clip-clop" sound, not even looking at Li Yue, only caring about bringing the news to the farther corridors.

And the skeletons who had just awakened immediately perked up when they heard this, just like the second half of a wine party, all eager to move in an instant.

The vegetables from the vegetable garden?

Li Yue subconsciously thought of Lockefell, thinking that she was the one who was exposed… Then Li Yue remembered that he had given the female thief the whole bunch of keys before leaving, and comforted himself that maybe it wasn't her, but other unprepared prisoners… or pigs.

Immediately afterwards, the skeletons heard that the vegetables from the vegetable garden had run out, and immediately abandoned the formation, rushing towards the corridor where Li Yue had come from in a swarm; Li Yue was also swept back the way he had come, and was stunned to find when he turned the corner… that the vault was gone.

The corridor no longer had golden light, nor armor in the shadows, and led straight to the stairs to the "vegetable garden", as if the golden door had never appeared.

The vault will be hidden when the alarm is raised?

Li Yue was both glad that he had stolen the Supreme Magic Stone and had a new understanding of the Demon King's Castle—Li Yue, who was running slower and slower, fell to the end of the team, and then took advantage of the skeletons' inattention to shrink into the shadows.

Groups of skeletons ran past, and after an unknown amount of time, there was finally no sound; Li Yue also hid in the shadows, and returned to the fork in the road leading to the library according to his memory.

The corridor was quiet, and the skeletons walking in the lower levels of the Demon King's Castle were all attracted by the "vegetables" and ran away; Li Yue didn't expect that releasing Lockefell would bring such benefits, and unhesitatingly pushed open the wooden door of the library and escaped back to the "home" in his memory.

The alarm bell behind the door did not affect this place, and the library was peaceful under the moonlight at this moment—Li Yue took off his disguise the moment he passed through the wooden door, restored his original brain spirit form, and then tightly clamped the Supreme Magic Stone in his brain grooves, and silently floated back to the fifth library.

A hourglass stood safely on the desk in the fifth library, as if it had been enchanted, and the flow rate was slow; at the same time, a reassuring wave lingered in his mind, and Li Yue returned "home".

Floating carefully, Li Yue did not sense any other brain spirits, guessing that the fifth library had been wiped out by Oogey Boogey, and not a single brain spirit was left.

The atmosphere was peaceful, and Li Yue almost had the urge to take a nap.

But the Supreme Magic Stone was still slowly emitting magic power. Li Yue knew that although the skeletons could not sense this thing, the brain spirits were more sensitive to magic power. He must complete the absorption now, otherwise it would be difficult to explain if he met the brain spirits from other libraries tomorrow…

Choosing a dilapidated hole in the wall of the fifth library, Li Yue drilled into it, used his mind to control the Supreme Magic Stone to float in the air, and operated according to the "eating" method in his memory.

The moment he saw the Supreme Magic Stone, Li Yue's main body's memory had a great effect, telling the newly promoted demon how to absorb the magic power in the magic stone.

As the memory came, Li Yue also read from it that after the brain spirit absorbs a magic stone of extremely high purity, its mental power, aura, and form will undergo certain changes, which will help to hide its identity—otherwise Li Yue would not have taken such a big risk to sneak into the vault and perform so hard to steal it back…

The magic stone is the condensation of magic power. The better the color, the purer the magic power it contains. Completing the absorption will also bring more magic power improvement—of course, for powerful demons like the Demon Secretary or the King of the Arena, the "Supreme Magic Stone" is just a broken stone, but placing it in front of a weak brain spirit is undoubtedly a feast that is difficult to swallow in one bite.

Using his mind to wrap the Supreme Magic Stone layer by layer, Li Yue tried to "knead" it, connecting the magic power contained in the core of the magic stone—the stable magic power crop would change according to the needs of the absorber, transforming into a form more suitable for "taking".

Of course, this method is limited to demons, and is one of the "conveniences" brought about by Li Yue's becoming a demon—if he were a human, he would need to use more magic potions, but Li Yue had no way of knowing what they were.

After an unknown amount of time, the black color of the magic stone gradually spread, flashing with flowing phantom light, and became a mass of "liquid" floating in the air.

Activated—Li Yue followed the instinct of his main body and sprinkled the "Supreme Magic Stone" liquid on his body, and then waited quietly.

The black liquid flowing with phantom light seeped into Li Yue's brain grooves, still flowing down continuously, gradually covering his whole body, and then seeping into his brainstem and medulla…

Until Li Yue was completely black, and there was not a single drop of the Supreme Magic Stone's liquid left, all of it was attached to the brain with its crisscrossing grooves.

At this moment, Li Yue seemed to have opened every cell in his body, opened all his body and mind—the memories of the previous life and the memories of this life, human logic and the instincts of the brain spirit all spread in an instant, and then dissolved, preparing to merge into something completely new…

Those bloodthirsty, numb, active, and entangled thoughts were tightly intertwined. Li Yue seemed to see a silent drama being staged in his mind. It could be said to be a dream, or it could be said to be the reconstruction and divergence of the present moment.

The scene was the home of his previous life, somewhat like a living room, except that what was hanging in the living room was not a clock, but the swaying demon fire of the Demon King's Castle; Li Yue "saw" his mother bring dinner out of the kitchen, it was his favorite beef stew with potatoes, but the soup was thicker, and there were some bones floating in it…

Many "people" were sitting around the dining table. Dad was sitting in his seat watching the news. On both sides of him sat a skeleton, each with his arm around Dad's shoulder, drinking wine with wooden cups; the news was reporting on the vegetable garden riots in the Demon King's Castle. Countless prisoners escaped and were arrested, and even more prisoners were torn apart by the mosaics in the picture.

After Mom put down the beef stew with potatoes, she raised her head and looked at Li Yue, her face full of worry, and then turned into the "angry" expression that often appeared on her face, as if she was blaming Li Yue for not returning home for a long time, and as if she was saying "take care of yourself"…

Li Yue wanted to reach for the chopsticks on the table, but he couldn't see his hands. Only the chopsticks floated in the air out of thin air, carefully avoiding the bones in the soup, and picked up a piece of marbled beef.

He picked it up, but couldn't bring it to his mouth, as if there was an invisible wall blocking all language and reality. Only the light of the skeletons and ghost fire traveled freely between the walls, revealing endless mockery.

Mom turned around to get another dish, but looked back before entering the kitchen, and a string of tears fell from the corner of her eye.

Mom!

Li Yue wanted to say it, but he couldn't convey this sound even with all his thoughts.

Then the wall shattered, the dream shattered, and all thoughts merged into one.

Li Yue was in a daze for a long time, and then came back to his senses, only to feel that the world was different, and his body had also undergone subtle changes.

The brain spirit was still the same brain spirit, but the color was a little darker—the medicinal power had stabilized, and the dream was over.

Like all those who wake up from a dream, Li Yue was still unsatisfied, but had to return to reality; the fifth library was still quiet, but the moonlight seemed to be brighter, maybe a long time had passed?

The surrounding walls were more concrete, and Li Yue seemed to be able to sense every tiny bump, but he never saw familiar faces again.

The magic power has been improved, but the "Supreme Magic Stone" has not been completely digested yet—Li Yue realized himself, and thought so.

I must become stronger—Li Yue spread out.

Strong enough to become the Demon King, to see through the mysteries of this world, to control everything here, maybe he can find a way back—Li Yue made a decision.

"You… are you back?" Li Yue heard a soft and glutinous double echo as soon as he regained his senses.
