I'm a monster in Demon King's Castle

According to Budibuger's memories, the Brain Spirit Master's skin during its peak period reappeared in the upper level of the library, in a large size.

Moreover, after Egg and Shadow's suggestions, this Brain Spirit Master, besides a huge brain, was also sewn with three Slaughter Sea Butterflies, a heavily armed macho man, sixteen octopus tentacles, and four or five brain grooves covered with "Magic Wolf Teeth." The bottom of the brain was also covered with dozens of pairs of lava right hands, like some kind of reptile…

All usable materials were used, and the binding threads were sewn several layers thick to barely sew them together.

Functionality isn't the optimal solution, but it looks lively enough.

Tearing open the Brain Spirit Master's outer skin, you can stuff a lot of good things inside—at the core, Li Yue piled up a large Slaughter Sea Butterfly, enough to fit an entire "Uninhibited Bony Trendy Man," completing a matryoshka doll of matryoshka dolls of matryoshka dolls.

Now, not only can Li Yue wear this "Brain Spirit Master," but Egg and Shadow can also control it with particles and shadows, and Budibuger can even barely drag it with his thoughts.

Of course, the mechanisms inside are a bit complicated for them. Extra effects like the lava right hand and octopus tentacles require Li Yue to control them.

But that's enough. As long as movement isn't a problem, Li Yue can make the "Brain Spirit Master" exert 100% of its combat power within a certain range.

"Friend, you've had your fun. Come out, it's our turn."

Egg was urging Budibuger to leave the Brain Spirit Master so it could jump in and play.

Budibuger emerged from invisibility and hesitantly asked Li Yue, "Master… the Slaughter Cup tomorrow night… can I not go?"

"No."

"Then can I… wear this outfit?"

"No."

Li Yue shook the tentacles on his head. "Whether you can survive tomorrow depends on your good fortune… I suggest you give up those useless fantasies and get familiar with how to escape."

Although Budibuger rediscovered his sensory object, Li Yue didn't think he was valuable enough to risk himself again—at worst, he'd die and start over, perhaps gaining a deeper understanding of escape.

【Escape… I must escape tomorrow night… escape as soon as the battle starts…】

Budibuger recognized reality.

"Think of it positively, at least the moment you participate in tomorrow night's final, you won't owe Ogibugi anything anymore, and you can live in the library in peace."

Li Yue also comforted Budibuger, "It can also be considered atonement for occupying the Brain Spirit's promotion channel for so long. Be calm and embrace death."

Li Yue drove Budibuger away, and after test-driving the Brain Spirit Master one last time and fine-tuning the handling, he came out, confirming that this skin was in perfect condition.

It looks ugly, but it's very useful.

In the following time, Li Yue silently calculated the possible changes in Demon King City tomorrow night, while sorting out the books in the library, sorting out books related to combat, military formations, breeding, and chaotic cuisine, to be used to set up new courses for the Brain Spirits and Mini Minis after tomorrow night.

Since Isaac of "Hero Studies" said that Demon King City might launch a new expedition, no matter what position the library occupies in the demon expeditionary army, strengthening its own combat power is still imperative.

Galarek can teach combat, and Big Brother Pig can teach demon cuisine.

While sorting out the books, Li Yue was also sorting out his thoughts—in Promotion Studies, clarifying Mentor's attitude, clarifying whether he will launch an expedition, clarifying the current situation in Demon King City…

What level is the authority of the library, what are the uses of the high authorities seen in the "Hero Studies" graduation class, what exactly does the King of the Arena want…

Li Yue has many questions to ask Mentor, enough to list a long letter.

During this period, the demon merchant Mai Mai also returned with profits as he wished. After deducting Reed Cote's share and Mai Mai's commission, the library's assets reached 270,000 gold coins, obediently piled in the chef's stomach bag—100,000 was the profit from the library's own inventory, and the other 170,000 mainly came from Reed Cote's principal.

Li Yue was also a little surprised that this red robe… does the red-robed bishop have so many valuable things that casually rummaging through them exceeds the entire library's net worth?

With these 270,000 gold coins, it is enough for Li Yue to splurge in the demon market—Li Yue's initial idea is to find some器具 or materials that can improve the overall combat power of the library, silently looking forward to the demon market trip.

By the way, while delivering Reed Cote's profits, Li Yue also used the Demon Illustrated Book to analyze the "Red-Robed Bishop" completely, and found that it was generally similar to the red-robed priest. After inquiring, Li Yue learned that Reed Cote had mastered more rituals. If he wants to "advance" to the next level, he should look for believers and synchronously conceive his own doctrine.

Not wanting to be persuaded by Reed Cote, Li Yue hurried away, and incidentally handed Reed Cote a bone card made of self-healing bone, with a cloak shape engraved on it, ready to try communication immediately.

"Staff of Deception?"

When Li Yue appeared again from the bone card as soon as he left, Reed Cote, who was proficient in various rituals, still had his eyes lit up and understood Li Yue's magic.

"Yes, contact me like this in the future."

Li Yue hurriedly cut off the spell, and felt sorry for the library's magic power loss—Li Yue only transmitted a figure, but the library's magic power for the day was instantly drained, leaving not a trace.

It only takes 20% to deceive Reed Cote, and Li Yue guessed that the remaining magic power consumption may be caused by the "Gate of Chaos," and he has a deeper understanding of the Staff of Deception.

But fortunately, the experiment was successful, and Li Yue was in a good mood. While watching Egg and Shadow driving the Brain Spirit Master and having a great time, he made a lot of bone cards.

Some of the bone cards were engraved with chains, some with wings, some with pig heads, some with rings… Li Yue was going to take these as graduation gifts for the closed combat training and distribute them to the "surviving" demon sons.

That way, even if the closed combat training is over, Li Yue can still maintain communication with the demon sons and learn about the major and minor events of Demon King City through them…

Even remote transactions are possible.

I believe they won't eat this weird bone card either.

When the moon was full, the fourth full moon of the Keel calendar 299 finally arrived. Budibuger rushed to the arena as scheduled to participate in the Slaughter Cup final, as if going to the execution ground; Li Yue and Egg and Shadow entered the Gate of Chaos together, each with their own thoughts, to participate in the graduation class of the closed combat training.

Li Yue has a lot of questions to ask Mentor, while Egg and Shadow expect the Demon King mentor to have some different "graduation" play methods, and to reap some good things and good nutrients.

Promotion Studies has not yet started, and the demon sons gathered together waiting for the class to start. Li Yue also took the opportunity to distribute the bone cards.

"I… am I the first to get it?"

Reed Cote's expression was a little strange when he saw the familiar bone cards, "Could it be… are we friends?"

"No, don't think too much."

Li Yue was a little afraid of Reed Cote's ritual that could only be completed by sacrificing friends, and shook his head to explain.

"So 'friend' is this feeling…"

Reed Cote seemed not to have heard, stroking the bone card in his sleeve, immersed in it and unable to extricate himself.

Taking the bone card, the reactions of the demon sons were different—Big Brother Pig swallowed it directly, as if he didn't want to leave the library; Damon Benben and Mai Mai exhausted all means to check it, without finding any abnormalities, unable to figure out how Scourge Rick would use this bone to complete the communication.

"I will definitely save it, save it in my most… important… place,"

Nate Meier was very greasy, and Li Yue pretended not to hear it.

When the red hour arrived, Mentor also appeared as scheduled, and without waiting for the students to speak, he divided them into seven groups, each teaching the demon sons, while the main body waved to Li Yue.

"You, come here."

Mentor greeted, and Li Yue obediently walked over, pulling at his list of questions.

"Listen, time is limited, very limited."

Unexpectedly, Mentor was a little anxious, but the worms on his chin showed a smiling expression, making Li Yue vaguely feel something was wrong.

What is this old thing happy about?
