I'm a monster in Demon King's Castle

"What are you doing?"

Shadow followed Li Yue through several caves, similarly dismantling a few other Imagined, and then watched as Li Yue found more than a dozen broken skeletons, repeatedly stabbing them, turning the entire cave into a smoky mess like a construction site.

Finally, the two demons arrived at the cave where the old mage was.

"Hey, if you don't speak up, I'll kill you," Shadow's arrow pointed at the twitching old mage. "You're clearly dead, are you whipping a corpse? But even whipping a corpse doesn't do any damage, what are you busy with? Just kill him and let's find a place to wait for Boodibooger."

Shadow thought Li Yue's actions were unnecessary.

"This is the place," Li Yue looked around the empty cave. "We'll kill Boodibooger right here."

Shadow couldn't understand how this was related to whipping a corpse.

"If you were Boodibooger, severely injured, and saw your home blown up like this, what would you do?" Li Yue asked Shadow. "By the way, Boodibooger is a very timid guy, I've already scared him away twice before."

"Scared away?" Shadow's curious and warlike nature meant he wasn't very timid, so he couldn't understand why a high-level demon, a Lord of Brains… would be scared away from his own library.

"Once was when he returned after his first night in the arena, and once was after Kele Ke'er died…" Li Yue briefly recounted his two encounters with Boodibooger.

"If that's the case… if I were Boodibooger, seeing this place blown up into caves and being injured, I would be very scared…" Shadow tried to put himself in Boodibooger's mindset, but accidentally strayed from the point, "Bosh and the others were also severely injured, you… do you like taking demons' lives when they're injured so much?"

Li Yue also felt that he was becoming a bit of a finisher addict.

"Weakness is a sin," Li Yue nodded to Shadow, firmly believing that in the dog-eat-dog world of Demon King City, doing so was perfectly fine.

"Weakness, fear… but at this time, the battle is not over yet," Li Yue brought the topic back on track. "Those skeletons, they just helped us create an atmosphere that the battle is not over, right?"

"Right," Shadow thought about the lively caves.

"So what should Boodibooger do without a safe area and nowhere to hide? Of course, find helpers!" Li Yue had almost predicted Boodibooger's reaction. "The closest helpers are his own Imagined…"

"So we want to kill his Imagined to cause him trouble?" Shadow hesitated. "But what if he can fix them quickly, then we've done nothing."

"Two situations, but neither affects him coming to us," Li Yue said firmly. "One is that he can't repair them, so he needs to confirm whether all the Imagined have been destroyed, and whether there are any survivors; the other is that he can repair them, but when one of the Imagined is abnormal, he must come to check."

"So… you want this old mage to be 'abnormal'?" Shadow understood Li Yue's plan.

"Yes," Li Yue transformed into the appearance of the old mage, extending three fingers from his left hand and pressing two fingers against his right hand, drooling and rolling his eyes, starting to twitch.

"Look, is it similar? Is there any problem?" Two identical old mages, one inside the cave and one at the entrance, twitching indistinguishably.

Shadow was stunned.

"Your plan has a flaw," Shadow thought along with Li Yue's performance. "Why do you think… Boodibooger won't be able to tell you and the Imagined apart?"

"Maybe he doesn't even need to get close to find out you're a fake."

"Oh, I've tried it, he didn't see it," Li Yue transformed back into the Book Demon. "At that time, neither Boodibooger nor his Imagined noticed."

"But it won't work with this skin," Li Yue transformed into Boodibooger's semi-incomplete form, and the old mage in the cave suddenly reacted, trembling and raising his hand, as if to hold the filthy heart in his hand higher, to unleash a vicious spell.

"You see, that's how it is," Li Yue transformed back into the old mage. "The Imagined's ability to distinguish is consistent with Boodibooger's, this is my speculation."

The images of those who had faced Boodibooger were firmly remembered in Li Yue's mind, constantly reviewing them, constantly "extracting" those extremely easily overlooked pieces of information, and finally piecing together the current ambush plan—Li Yue never gave up thinking about Boodibooger's life.

"But how can you be sure? There are too many speculations and assumptions in your plan," Shadow disagreed.

"In the Brain Spirit's perception, 'location' is a very important part," Li Yue had not yet announced the complete plan. "So we also have to ensure that this Imagined is not very far from me, and completely loses its combat ability, with no possibility of being repaired…"

"Shadow, control him and don't let him move, leave the heart."

Shadow didn't know what Li Yue was going to do, his shadow merged with the old mage, completely controlling the old mage's actions; and the filthy heart also fell on the ground, bouncing.

Like a crash, the twitching old mage suddenly froze, and at the same time Li Yue suddenly rushed towards him—this time, Li Yue did not use the bone sword to stab, nor did he release the skeletons to act, but instead unleashed the Lava Fist with all his strength!

The range of the lava expanded with Li Yue's thoughts, and then wrapped the old mage!

In a burst of sizzling sounds of barbecue, the old mage was completely covered in lava, trembling as he burned, shrinking, and finally froze into a round, bulging stone pier, blending in with the cave.

"In this way, Boodibooger can sense that the Imagined is here, at least it can deceive him for a moment," Li Yue said, transforming into the appearance of the old mage, picking up the dirty heart from the ground, and starting to twitch.

"But I still don't understand," Shadow was completely unaffected by the lava, retreating from the shadow of the stone pier to the edge of the cave. "For a sneak attack, it would be better for you to enter the shadow space, it would also scare Boodibooger."

"If you can scare him three times, why only scare him once? Anyway, he's timid," Li Yue was creating more opportunities to strike, more possibilities to kill Boodibooger. "When Boodibooger comes here, you kill him from the shadows, I kill him from here, who comes first?"

"Of course it's you," Shadow actually had multiple considerations. "If this causes a war, you will definitely be the one to bear the demons' anger, not me."

Although Shadow was warlike, he wasn't stupid.

"No problem, I, Skullrick, will not shirk my responsibility," Li Yue patted his chest while twitching his trembling hand—I've endured the Demon Wolf King's malice, who else am I afraid of?

Moreover, Li Yue sincerely didn't think there would be any existence protecting Boodibooger, otherwise this Lord of Brains wouldn't be so afraid, and wouldn't be forced by Oogey Boogey to fight in the arena.

"Then what if Boodibooger is so timid that he doesn't die after being attacked, and wants to escape?" Shadow thought carefully. "For example, escape to there?"

Shadow pointed to the core area where the "cloak" was located—at this moment, Li Yue was almost completely certain that it was the resurrection altar of the library.

"It's very simple, if he wants to go there, we must not let him go there; if he doesn't want to go there, then we can force him to go there," Li Yue said quietly.

Shadow didn't understand.

Li Yue's logic was very simple—Boodibooger had been in the upper layer of the library for decades, he should be the demon who knows the resurrection altar best, if he actively wants to go there to save his life, then Li Yue will stop him; if he is afraid of going to that area, then it means there is a great danger there, which can be used to force Boodibooger to die when necessary.

And with the help of the Demon Illustrated Handbook, Li Yue has a more than 50% success rate in predicting Boodibooger, which is enough to repeatedly verify Boodibooger's attitude towards the core area.

"Next, we still need to do this…" Li Yue counted the remaining bones, barely gathered ten skeletons to release, and then each held two barbed nets, walking into the shadows on the side of the cave.

"Keep my trump card safe," Li Yue instructed Shadow. "When you rush at Boodibooger, throw them out, maybe they can be of some use…"

Li Yue imagined Shadow attacking Boodibooger, and at the same time summoning this team of skeletons from the shadow space, whether it was a sea of bones or a barbed net, they could become a brain-breaking method.

"This scene must also be perfect…" Li Yue used the last remaining bones to piece together a few broken skeletons, and dinged and clanged at the stone pier under his feet with the blunted bone sword.

Li Yue used all his trump cards, striving to kill Boodibooger—Withered Thorn, bone sword, barbed net wolf teeth, lava fist… as long as one can hit Boodibooger's main body, it should be able to get rid of him.

After all, the Brain Spirit's weakness is "everywhere."

Li Yue's only worry was Mento's blessing, most afraid of "rebellion"—but this was not within Li Yue's control, the only contingency plan was that if the "rebellion" took effect in the heat of the battle, he would summon otherworldly demons to create chaos.

Let's all die together.

Finally, Li Yue and Shadow each took their positions, the cave where the old mage was located returned to calm, Li Yue performed the twitching meticulously, until the phantom body really had some spasms…

Boodibooger returned.
