I'm a monster in Demon King's Castle

Li Yue was unaware that Oogway had already dispatched Bodley Corley, a gladiator ranked 281st in the Colosseum known as the "Slave Master," to find him, but he wasn't naive enough to think the matter would simply blow over. Google Search Read

After resting for nearly three hours, Li Yue gathered the fluctuating magic within his body and took the opportunity to recall the daily lives of the Brain Spirits, seeking a way to perfectly "integrate"—the library was the place Li Yue's main body was most familiar with, and he certainly wouldn't abandon his existing identity there to disguise himself as a skeleton soldier, attending to Oogway's every need.

Every morning, the Brain Spirits would gather in the library's hall to begin their day of translation work—the division of day and night in Demon King City was very clear, so clear it seemed like a mere concept, not based on natural arrangements.

Daytime, the period of intense moonlight, lasted 16 hours every day, without exception; nighttime, when the moonlight was dimmer, lasted 8 hours, roughly from 8 PM to 4 AM the next day, similar to human society.

During the 16 hours of daytime, the Brain Spirits were sandwiched between Mini and Minnie and the Slave Scholars, translating the endless books of the library, not much different from being in prison.

Except there were no lunch breaks, no fresh air, no need to drink water, no need to eat—that was the Brain Spirits' productivity.

What made Li Yue feel even more apprehensive and uneasy was that the Brain Spirits' translation process wasn't always smooth sailing—after all, the books in the library covered a wide range of topics, and some forbidden books contained curses with extremely strong malicious intent; a slight carelessness could cause the Brain Spirits to explode and die, making it a very dangerous job.

So yesterday, when the Brain Spirits of the Fifth Library learned they could go to the Colosseum to participate in the Slaughter Cup, each one was so brave and joyful, even though only Li Yue ultimately returned.

Yesterday's battle took place during the 8 hours of night. The defeat of the Demon Wolf Fendis was followed by a night of revelry and Li Yue's prison break and treasure theft.

This morning at exactly 4 AM, new Brain Spirits would be born from the First Library to replenish the Fifth Library's fixed number of 15 Brain Spirits—the library had 4 regularly operating libraries, namely the Second to Fifth Libraries, each with 15 Brain Spirits, totaling 60.

The Sixth Library was located in the deepest corner of the library's lower level and was transformed by the Brain Spirit Master, Buddy Bog, into a dormitory for the Slave Scholars, allocated for them to sleep—the Slave Scholars were humans, humans captured by the demons of Demon King City, all proficient in the common demonic language of Chaos, with an average lifespan of about 3-5 years.

It wasn't that the humans of the Chaos Continent only had such short lifespans, but rather that Demon King City's care for these humans was limited to this—every day, the Slave Scholars wore heavy shackles and, like the Brain Spirits, worked 16 hours a day, with half an hour for eating and excretion in the morning, noon, and evening, and then, after a busy day of work, they would return to the Sixth Library at 8 PM to rest, waiting to get up at 4 AM the next day to continue working.

Recalling this, Li Yue even felt a little fortunate that he had transmigrated as a Brain Spirit, rather than a Slave Scholar in an even more miserable situation…

Currently, there were about 40 Slave Scholars in the library, give or take… depending on whether any of them died in their sleep tonight; in terms of age, they ranged from 22 to 72 years old, mainly concentrated between 22 and 32 years old, with only three elderly Slave Scholars who seemed to have learned some magic during the translation process, enhancing their physique and survival ability, reaching the advanced ages of 67, 69, and 72 respectively.

However, Slave Scholars were not like Brain Spirits, who could be replenished from the First Library—they were all captured by the Demon Expeditionary Force from various parts of the Chaos Continent, and once casualties in Demon King City became too heavy, it would delay progress, but there was no way to prevent it, so they could only wait for the next expeditionary force to bring back some new ones.

So, in terms of status… the Slave Scholars had a slightly higher status in the library than the Brain Spirits and were more valued by the "Book Demon."

In Li Yue's main body's memory, the Book Demon was a huge book, controlling all the power in the middle and lower levels of the library—the fragmented papers translated by the Slave Scholars would be thrown into its giant mouth by Mini and Minnie.

After chewing, the Book Demon would bind the scattered papers into volumes, thus becoming complete, translated demon books, which would then be sent to the Seventh to Twelfth Libraries for the demons to borrow or "desecrate."

Yes, desecrate—demons never read books elegantly; some demons even came to the library to borrow books… just because they didn't have enough toilet paper.

The Demon King City's library had a total of thirteen libraries. The First Library was the birthplace of the Brain Spirits, the Second to Fifth Libraries were Brain Spirit dormitories, the Sixth Library was the Slave Scholars' territory, and the Seventh to Twelfth Libraries were storage rooms…

Li Yue had little impression of the Thirteenth Library; he had never been inside and only remembered that there was a menacing bone door blocking all the demons, even the Brain Spirit Master Buddy Bog himself couldn't enter.

If the Book Demon was the manager of the library hall, then Buddy Bog was the power of the library itself—Li Yue had never faced this Brain Spirit Master directly, only knew that it occupied the upper level of the library and hadn't interacted with anything in the lower level for nearly ten years, not knowing what it was busy with.

Thus, under the watchful eye of the Brain Spirit Master, the Brain Spirits, Mini and Minnie, and the Slave Scholars on the lower level of the library translated day after day, bound by the Book Demon's giant mouth, eventually perhaps becoming the knowledge with which the demons ran rampant, or perhaps becoming their toilet reading or even toilet paper…

This was the basic ecosystem of the library.

As an insignificant link in the food chain, Li Yue decided to go to the First Library before 4 AM this morning, "born" with the new Brain Spirits, join the library's translation army, and become a Brain Spirit again.

At exactly 4 AM, the red sand in the magic hourglass flowed, turning green on time—the magic hourglasses in Demon King City were usually set to flip every 8 hours, and the color of the sand at the three time points was different: green from 4 to 12, blue from 12 to 8 PM, and red from 8 PM to 4 AM the next day.

Li Yue left the wall hole, came to the door, and after confirming that there was no one in the corridor, instantly sped away and waited at the entrance of the First Library.

Creak!

The iron door of the First Library rumbled, like a giant mouth opening, revealing the magic-filled darkness behind it; the newborn Brain Spirits were born on time, and they floated out in a rush, fourteen of them, forming a complete squad with Li Yue.

At the same time, the Brain Spirits in the Second to Fifth Libraries in the corridor also floated out—they were half-awake, numb and ethereal, gathering into a tide of the walking dead, surging and filling the corridor, heading towards the library hall.

This scene inexplicably reminded Li Yue of the subway during rush hour in his previous life.

No Brain Spirit noticed Li Yue's specialness, or perhaps in their perception, Li Yue was nothing special—they all stared blankly ahead, as if trying to glimpse the future like lambs to the slaughter.

Only the newborn Brain Spirits were a little restless, but the newly surged enthusiasm was quickly washed away by the numbness of their peers, drifting with the tide.

However, Li Yue subconsciously wrapped his perception around his peers, only to remember that he had already collected 5 kinds of "demons" here, but he hadn't even looked at the Brain Spirit's own information?

[Analyzing… 80%… ]

Having absorbed the Supreme Magic Stone, Li Yue's Demon Illustrated Handbook's analysis speed was obviously enhanced; the Brain Spirits' teams hadn't even reached the hall yet, and they had already become a constantly looping animation in the Illustrated Handbook.

Weakness… everywhere?

Even though Li Yue already knew that Brain Spirits were weak, he didn't expect the description "everywhere" to appear not only under "Distribution" but also under "Weakness."

Thinking this, Li Yue hid in the team of 60 Brain Spirits and arrived at the library hall, like workers arriving at the factory on a bus.
