I'm a monster in Demon King's Castle

Li Yue sensed the card faces of the three cards and naturally saw three worms with different expressions and forms—one with a look of intoxication, but all the plants, trees, and insects around it had expressions of disgust, avoiding it from afar; one clinging to a planet, sleeping soundly, but in the boundless universe, countless eyes were staring at it; and the last one was under a few ferocious black mists, its body twisted and broken, as if it had been burned into a blur by something.

“Is the Blessing under your control?” Li Yue immediately recognized that these were the three Blessings of Loathing, Notoriety, and Rebellion, and immediately associated them with several very coincidental activations, questioning Mentor.

“Do you even need to ask?” Mentor retorted, “A brain spirit infiltrated a closed battle training; shouldn’t I be watching at all times?”

“A brain spirit, who luckily pierced a drop of Holy Blood in the Battle of Steel City, deserves a reward, but still has to haggle… Shouldn’t he be taught a lesson?” Mentor was also quite speechless towards Li Yue.

“You can watch, but these three Blessings are difficult to handle; I almost died at their hands…” Li Yue muttered.

Vinnie and the Magic Wolf King Fenrir were both brought about by "Notoriety," inexplicably exposing the fact that "Bosh and the Magic Wolf Fenrir were killed by Skollreik."

Li Yue felt that after the next full moon, he must use the "Sharp Boned Beauty" skin less often and kill off the identity of Skollreik.

Otherwise… he might die without even knowing how.

“If it weren’t for them, would you have your current strength? To be enveloped by hatred and chaos… This is a demon’s fortune.” Mentor's reaction was as if he had done a good deed.

“Remember what I told you… about the advancement rule that applies to all demons?” Mentor suddenly tested Li Yue.

“Mutation?” Li Yue had the memory of a brain spirit; Mentor's reminder immediately brought it to mind—strong emotional and environmental stimuli can trigger the mutation of demon creatures.

Mutation would bring unpredictable changes in form, so Mentor gave himself these three "Blessings" mainly to stimulate his evolution?

“And the known important factors that trigger mutation… are absorbing enough hatred and experiencing enough chaos.” Mentor added, “These are all very beneficial stimuli, for demons.”

“Now it seems, you still exceed my expectations…” Mentor pinched the shadow beside Li Yue, threw it aside, and sat down next to Li Yue.

The shadow seemed oblivious, probably learning one-on-one with the “Mentor” in front of it.

“I didn’t expect… you could actually break the influence of ‘Rebellion’ and bring me ‘It’.” Mentor pointed to the egg in Li Yue’s arms.

Sure enough, the “Summoning” being difficult and the Dagger of Decay repeatedly failing at that time… were all related to Mentor.

At that time, Mentor didn’t want him to kill Budibog?

While Li Yue was still thinking, the egg had already sent greetings to the Demon King instructor: “Hello, nice to meet you, I am Egg, ‘Spade’ larva, the master of the home planet, the wandering garbage of the universe, indestructible ultimate matter…”

At this time, Mentor was very patient, quietly listening to Egg finishing the introduction of its titles, ignoring all the flaws, and turning to ask Li Yue: “Where did you find it? What ritual did you use?”

As soon as Mentor asked, Li Yue couldn’t help but think of the existence of the Demon Illustrated Handbook, and quickly changed his mind—this was the only thing Mentor didn’t know; he couldn’t let him see through it…

“Oh… I really didn’t expect there to be such a thing as the Demon Illustrated Handbook; no wonder you can do those things…” Although Li Yue didn’t answer, Mentor still read the existence of the Demon Illustrated Handbook from Li Yue’s reaction, “Is this also some kind of ‘mutation’…?”

Li Yue was speechless, but no matter what Mentor said, he no longer thought about the functions related to the Demon Illustrated Handbook, but instead relived the book about the “Weaving Women” in his mind, his mood quickly calming down.

“Factory? Revolution? Weaving Women?” Mentor seemed to be able to see the associations in Li Yue’s mind, “Sometimes… I really don’t know how to evaluate you.”

“Cowardly like a mouse, yet arrogant enough to attack the Lord of Brain Spirits…” Mentor folded his hands, quite helplessly: “You don’t need to be so afraid of me at all; if I had malicious intentions towards you, you would have died in the Blood River.”

Li Yue thought that if he received even a little malice from you… I would run away.

“In short, since my ‘Blessings’ have been broken by you, then let them be a gift for you to use as you please.” Mentor threw the cards in front of Li Yue’s desk, and then folded his hands again, looking at the egg, as if he was repaying Li Yue for sending the “Otherworld Demon” as a return gift.

The egg seemed to be picked up by a hand, separated from Li Yue’s embrace, and placed on the table.

“How to use them?” Li Yue knew he couldn’t defy Mentor’s will, temporarily giving up guarding the egg, and sensing the three cards on the table, vaguely feeling that his fate was closely related to them.

“You can understand it as a kind of demon relic; when you need it, just turn the card face to the front.” Mentor introduced the use of the three Blessings, “Of course, suppressing the card face is also very important at ordinary times; they want to merge into reality at all times, so they will also secretly turn themselves over when you are not paying attention, acting on the master…”

“If time goes on, they will stay with you forever, never to be dissolved, until you die.” Mentor seemed to be reminding Li Yue that the cards were alive, “Remember, hatred and chaos can be a curse, but often, they are also gifts, graces from this world…”

“They only act on me?” Li Yue didn’t pay much attention to what Mentor said later, asking the most critical question.

“Of course not; demon relics never belong, only see who has a way to control them.” Mentor showed Li Yue his power, “There are not many in this world who can bestow blessings on you across space and control your destiny.”

“Understood, that’s great.” Li Yue quickly conceived the simplest use of the three cards—flying cards; whoever they fly to will be “Loathed,” whoever they fly to will be “Notorious,” whoever they fly to will be “Rebellious”...

“Then what about the remaining three?” Li Yue reached out again, asking for “Concealment,” “Absorption,” and “Completion.”

Mentor was always stunned by Li Yue’s greed: “Those three… are my magic, not yours.”

“Okay.” Li Yue now seriously suspected that the “Blessings” could only last until the next full moon, which also led Li Yue to indirectly guess… Mentor’s activity cycle in the library was only for such a period of time.

Without Mentor, the library would truly belong to him—he had to figure out a few key questions before then.

Advancement, authority, and Mentor’s purpose—he had no malice, but what benefit would he get if he became the Demon King?

“Is this my ‘Advancement’?” Li Yue returned to the original intention, “In addition to those of the brain spirit itself, to embrace loathing, notoriety, rebellion… to obtain ‘mutation’?”

“Aren’t you already practicing it? Provoking and killing everywhere…” Mentor said dumbly, “And also vying for the authority of the library?”

“Then I would like to ask about your purpose… At that time, you didn’t want me to kill Budibog?” Li Yue finally couldn’t help but throw a fastball at Mentor—this Demon King instructor always thought highly of himself, even casting spells to send fatal “Blessings” and demon relics; what exactly did he want to do?

Since he had no malice, it would be better to speak frankly now and stop guessing.

“I…” Mentor tilted his head slightly, the worms on his chin trembling again.

But just at this moment, a voice rudely interrupted the conversation between Li Yue and Mentor—Egg.

“Hey, it’s very impolite not to answer when others are introducing themselves.” Egg had been ignored by Mentor for a long time, and finally couldn’t bear it anymore, “You old fart.”

Li Yue was a little dazed—daring to say that to Mentor? Yingying had already explained it very clearly before; the Demon King instructor was obviously the top combat power of this planet; were the Spades all so reckless?

However… maybe it was intentional—Li Yue thought of Egg’s “obsession” again.

“Your understanding of ‘politeness’ is very superficial.” Mentor was not angry at all, “Did you hear it?”

As he said that, Mentor stretched out his hand and wiped the egg, and the fine particles of the egg combined into a bowl shape, like a small radar.

“Right? Just like this, learning the language, writing… and politeness of this world.”

“So what? You old fart.” Egg became even more presumptuous.

【Hit me… hit me quickly…】

Hearing Egg’s inner voice, Li Yue suddenly remembered something and made a move that surprised Mentor again.

Taking out the Bone Sword, shrouded in death energy, Li Yue gave Egg a “Dagger of Decay”!
