I'm a monster in Demon King's Castle

Li Yue thought it was perfect—he had taken a trip to the Forbidden Forest and had a good idea of what the Killing Cup was all about, so it was the right time to talk to Oogway Boogway about how to fight this battle.

"Master, you're back…" Of course, the letter was delivered directly to Budibooge here, so next to the altar floated the former Brain Spirit Master, plus Lulu and Feifei, the left and right guardians of the library.

The two Mini Minis each pinched a headless fly, running over covered in sweat to claim credit: "Brother, according to what you said, no idle monsters allowed, but these two flies delivered a letter and were still acting suspiciously, so we killed them."

The Mini Minis, who can stretch their arms, are no less capable than the tiger-striped gecko when it comes to catching flies. Li Yue was very pleased—looking at the flies with their heads cut off just right, Li Yue suspected that Lulu and Feifei's swordsmanship had reached extraordinary heights.

"The letter, open it." Li Yue flattened the two flies and their remaining heads as if stepping on beans, signaling Budibooge to read the letter.

Opening the letter, there was another series of magical fly explosions, leaving Oogway Boogway's message: "Third round, hand the battlefield over to the Gnoll family. Only in the third round can you kill them."

"Read and burn…" Just like last time, the letter turned into an invitation, dirty and grimy.

Li Yue chuckled—Oogway Boogway never tires of the routine of "getting beaten first and then reversing the situation." He must be planning to absorb a lot of bets in the first two rounds and then have a bulging wallet in the end.

But this time, Li Yue didn't plan to follow Oogway Boogway's rhythm—during tonight's observation and learning, Li Yue fully realized that the Gnoll family should not be underestimated, especially Mandena, who wields the "Staff of Deception," which could easily add a lot of variables to this Killing Cup.

If they were given enough time and opportunities, once the library's side fell into a disadvantage, it might never be able to reverse the situation.

"Come, Left Guardian, help me write a letter." Li Yue called out to Lulu. Lulu's eyes lit up, and she leaned over happily.

At the same time as approaching, Lulu stretched out a hand to the distance, dragging a quill and tattered stationery from the pile of debris in the cave, sitting upright next to the bath and starting to write.

"Greetings…" Li Yue read, Lulu wrote, "Fourth match, we will kill the entire Gnoll family in the first round…"

Li Yue had only written half of the letter when Yingying and Dandan were both a little touched and had some reactions of their own.

"As expected… this crazy guy… wants to kill the whole family in the first round." Yingying bulged slightly, looking forward to it even more.

"Really? The first round…? Shouldn't we slow down a bit?" Dandan was afraid that one round would not be enough.

"Remember, it's the first round, the rest is up to you." Li Yue's letter was very short, and it was finished in a few words.

From beginning to end, no one cared about how the Brain Spirit Master himself wanted to reply.

Lulu carefully folded the stationery, suddenly got stuck, not knowing how to deliver it, and then threw it into Feifei's mouth: "You send it…"

"Wait, wait…" Li Yue also realized this problem and took the letter from Feifei's mouth—Oogway Boogway obviously relied on flies to deliver letters, and should have also added some kind of magic, which he didn't know how to do.

"I'll go!" Dandan understood Li Yue's hesitation and volunteered, having long wanted to go to the arena to get beaten, "Shadow friend, do you know where the arena is? Take me there!"

It was indeed impressive to have the Demon Child deliver the letter, but they had just made a big fuss in the Forbidden Forest tonight, and if they were to ask the same Egg and Shadow to deliver the letter again… it wouldn't be good, it would affect business.

"It can't be you." Li Yue was prepared to gamble all the materials in the storage room, so before the war started, he still couldn't reveal the true strength of the library.

"Redcoat?" Yingying thought of the deal proposed by the red-robed priest—this priest must have a way to directly throw the letter into the arena like Oogway Boogway.

Li Yue also thought of the same channel, but hadn't yet decided whether to help Redcoat with this favor…

Right, help Redcoat with the favor, he seemed to have a great obsession with holding a "ritual" in the arena.

As for delivering the letter… it wouldn't be impossible for the Brain Spirit to deliver it—with Oogway Boogway's fly corpses protecting him, from the Maze Corridor to Moonlight Path, and then to the arena, there shouldn't be any short-sighted monsters daring to stop him.

What's more, the skeletons in the Maze Corridor… had already been trained by the "Little Noisy" to run away when they saw the Brain Spirit.

"Or… why don't you go and deliver it?" Li Yue stuffed the fly corpses and letters into Budibooge's brain grooves, scaring the Brain Spirit Master into convulsions on the spot.

"Wait! I know a Brain Spirit who can! It's perfect!" Lulu suddenly slapped her forehead and jumped up high.

"Who?" Li Yue had been focusing on creating the "Killing Sea Butterfly" template and preparing for the Killing Cup, and hadn't paid attention to the Brain Spirits' situation for a long time.

"Menmen!" Lulu shouted, the sound amplified several times by the cave, falling directly into the middle layer of the library.

Li Yue also used the library's authority to locate where Menmen was, and was stunned to find that this guy was repeatedly opening "doors" in the middle and lower layers of the library, sometimes drilling into the toilet of the Sixth Library, and sometimes floating out, which was unpredictable.

Hearing the Left Guardian's call, Menmen first rubbed his brain on a doorknob, and after confirming it, he opened the door and drilled out of the door of the Twelfth Library, coming to the upper cave.

"Did you finish it?" Li Yue transmitted his thoughts to Menmen, asking about his "soaking" progress—Li Yue didn't expect that there would be a Brain Spirit who would complete the "soaking" of the sensory object in more than half a month.

It may be related to the magic power allocated by the authority, which accelerated Menmen's progress—after completing the ritual and seizing the library's authority from Budibooge, Li Yue allocated half of the library's magic power to the Brain Spirits and Mini Minis, and now they were visibly growing strong.

Even so, from the outside, Menmen was still a thin Brain Spirit, who, before being assigned the "soaking" task by Li Yue, liked to drill in and out of the cracks of several broken doors in the library, honing his brain.

"It's done." Menmen trembled his brain. Although he was thin, he was much more majestic than Budibooge in terms of momentum.

Li Yue also learned about its progress from the thoughts transmitted by Menmen—"door" had become Menmen's sensory object, and as long as he moved his mind, he could complete the transfer between door and door.

"Doors without magical seals can currently be used." When Menmen introduced his abilities, his thoughts also revealed stability, "However… only 'doors' can be used, walls are not yet possible, and ranges beyond a hundred meters are not possible either."

"What, do you want to deliver a letter?" Menmen guessed Li Yue's thoughts when he saw Lulu pointing at the letter and winking, "I can run a few more times."

"Aren't you afraid of death?" Li Yue had never understood Menmen's inner world, and didn't expect him to be much more powerful than Budibooge.

"I'm not afraid." As a curious baby who often shuttled through various door cracks, Menmen was very different from Budibooge, "And I want to try… after I die, will 'door' still be my sensory object."

Li Yue looked at Menmen with new eyes—General Doorman?

"Okay, I'll leave this task to you. You can jump through a few more doors, but the letter must be delivered before tonight, and then come back." Li Yue instructed Menmen a few words, "Don't die, if you die, you have to 'soak' again."

Li Yue made this judgment based on Budibooge's current state—the Brain Spirit Master must have 'soaked' a lot of things before he died, but now he was still clean and smooth, so the answer was obviously no.

"Okay." Menmen nodded his brain, "Everything is as you wish…"

Li Yue didn't know where Menmen learned this word from, and waved his tentacles to let him leave.

All the communication between the two Brain Spirits was done through telepathy. Yingying, Dandan, and the left and right guardians only saw a brain suddenly come and go, with a back view that was quite determined, admiring Li Yue's leadership ability.

"Okay, let me think…" Li Yue shrank into the ground, combining today's illustrated book update, "immersively" thinking about how to fight the fourth match.

"Yingying, I have something to tell you." Li Yue had only shrunk down for a short time before climbing up again.
