I'm a monster in Demon King's Castle

Before the appointed time, Li Yue had already placed Budiboge, clad in the "Slaughter Sea Butterfly," on the throne in the bone chamber's reception room. He himself donned the octopus head and blended into the bone chamber's walls, directing from afar.

In any case, the "Slaughter Sea Butterfly" was originally Budiboge's preparation for the fourth round of the Slaughter Cup, so it didn't matter if it was revealed to Damen Benben now.

With Egg's warning, Li Yue certainly wasn't comfortable letting Budiboge perform this scene alone. Moreover, this former Brain Spirit Lord only wanted to escape, so Li Yue had no choice but to directly take over his consciousness—just like he did with "Octopus Shapeshifter" Keli.

Therefore… this negotiation had completely become a negotiation between Li Yue and Damen Benben, and the location was also Li Yue's home turf.

Damen Benben and Nete Meier arrived on time, hand in hand, floating into the reception hall. Looking at the bone spurs and demon wolf teeth on the ceiling, floor, and walls, they couldn't find a place to stand and could only continue floating.

And when he saw Budiboge wearing the "Slaughter Sea Butterfly," Damen Benben was momentarily unsure if he had found the right demon. Nete Meier was also a bit dumbfounded.

Li Yue, using Budiboge, transmitted a thought to the two Demon Sons: "You are very punctual."

"Oh, my esteemed Lord Budiboge, it is an honor to finally meet you…" Damen Benben felt the Brain Spirit's thoughts and hurriedly greeted the seashell on the throne. Nete Meier couldn't find a target to flirt with and could only stare blankly at the "Slaughter Sea Butterfly."

Li Yue responded with the bone spurs in the room, which landed with a "clang" above Damen Benben and Nete Meier's heads.

"Ah—" Nete Meier screamed and clung to Damen Benben, but Damen Benben forcibly restrained himself from moving.

The bone spurs narrowly avoided causing them harm, outlining two extremely delicate three-dimensional shapes in the room.

【Vault… Father… He wouldn't dare…】

Damen Benben also pretended to be calm, invoking his father's name in his heart.

Li Yue established his authority, declaring his absolute dominance in this room.

"You are indeed even more powerful… Have you obtained a new power?" Damen Benben pointed to the bone spurs all over the room. "How many are there? 66, 96…"

Damen Benben's tone was relaxed, as if just chatting casually, but he started counting on his own.

Remembering the Demon Secretary's "twisting" and "tampering" with numbers, Li Yue immediately dismantled dozens of bone spurs, instantly covering the ceiling densely again, and they fell once more.

The bone spurs were about to pierce Damen Benben again, but stopped—Li Yue didn't intend to really kill the two Demon Sons, as long as he ensured they wouldn't be detrimental to him, he could allow some degree of probing.

After all, he had already killed Bosh and his group and Finley. If he killed Damen Benben as well, the Library might become the target of public criticism.

"Oh, oh, I'm sorry, I made you misunderstand…" Damen Benben gave up counting and looked seriously at Budiboge in the Slaughter Sea Butterfly. "It seems you have obtained some ability from the Skeleton Race. Are you cooperating with that guy Skollreik?"

Damen Benben was afraid that he had aroused Budiboge's hostility and hurriedly added, "I am also a Demon Son, the Demon Secretary who controls the Vault. Perhaps… we can talk about some more in-depth cooperation?"

"So that's why you appeared here." Li Yue controlled Budiboge and transmitted his thoughts to Damen Benben and Nete Meier together, while the six bone spurs moved in unison, displaying an uncontrollable appetite.

After testing each other, the two sides entered the main topic.

"I want to know… how you will win in the fourth round of the Slaughter Cup." Damen Benben fiddled with the chains around him, still looking nonchalant. "Name your price."

"You can also leave the Library? You guys?" Li Yue meticulously played the role of a Brain Spirit with unequal information—Li Yue knew that Mentuo had opened the restriction, but Budiboge didn't.

However, even though he didn't know, it didn't affect the Brain Spirit Lord "guessing" Damen Benben's purpose.

"The fourth round of the Slaughter Cup, you also want to bet, so you came to me in advance to ask for inside information?"

"After asking, you will decide how to bet?"

Accompanying Budiboge's telepathy, Damen Benben's chains trembled even more violently.

【His demon cocoon… mind reading… memory reading?】

Damen Benben was frightened—he clearly hadn't said anything to Budiboge, but He knew everything?

No, did Skollreik tell him? That makes sense…

Damen Benben raised his head again: "I really didn't expect that the Brain Spirit Lord's relationship with the Skeleton Race would be so good?"

【Ask the Skeleton…】

Li Yue guessed that Damen Benben would come back to ask him—but this didn't affect the deal at hand.

"Maybe…" Budiboge didn't explain whether the Skeleton had told him, but talked about the next step of the deal, "If you can leave the Library, why not ask O'Keeffe?"

"I think that guy… would be very happy to do business with you." Even now, Li Yue didn't know whether the Gambling Demon had paid off his debt to the Vault, but it was obvious that the two sides had some degree of information sharing. Asking a question could just show the Brain Spirit Lord's omniscience and omnipotence.

"This… you are the one who dominates that battle, I choose to trade with you." Damen Benben was convinced and was secretly jealous of Skollreik—this Skeleton had not only become a family with Egg and Shadow, but even had a close relationship with the Brain Spirit Lord. No wonder he dared to kill Bosh and Finley…

"Name your price, and see if I can afford it."

"My price… is… I hope to have a good trading relationship with the Vault." Li Yue quoted the "price" he had thought about long ago.

In the transaction with the Demon Kitchen, Li Yue had accumulated a large number of redundant materials, and those that could not be used needed to be exchanged for some common currency—such as gold coins and magic stones.

In this way, whether it is in the future or in the upcoming Demon Market, he will be less restricted by the type of transaction… After receiving the reward for the fourth round of the Slaughter Cup, he can shop with confidence.

At first, Li Yue did hesitate… whether to bet with the Demon Merchant or with the Demon Secretary; but when he thought that the contract with Mai Mai had been reached, the profit was much more stable than with these guys who could "tamper" with numbers, so he didn't bother.

"But you know… the owner of the Vault's authority… is my father, Damen Kirk…" Damen Benben didn't dare to promise Budiboge a blank check—basically, Damen Benben had already determined that the Library had reached a cooperation with the Skeleton Race's Light Tomb, which could be seen just by looking at the bone chamber.

"You who have participated in the closed training… you still haven't opened your eyes?" Li Yue asked rhetorically, "In the future, won't the owner of the Vault's authority… be you? And… now, you should also have some jurisdiction over the Vault, right?"

"…Yes, okay." Damen Benben had nothing to say, and suddenly felt that having the Library as a trading partner… could effectively increase his wealth share in the Vault, a real win-win.

As for why the Brain Spirit Lord, who had rarely communicated with the outside world before, would have such a change… it was no longer something Damen Benben cared about.

"Then… let's sign a contract to ensure that the Library and the Vault trade fairly at market prices." Li Yue used his mind to control Budiboge to protrude his brain, using this agent to the extreme.

The "market price" has a huge impact, Damen Benben cannot distort it, and there is no possibility of cheating.

"Oh, right, I also want to make sure you promise… to restrain your behavior during the closed training period and not cause any chaos to the Library." Li Yue added another layer of insurance.

There were only a few days left until the next full moon, and Damen Benben didn't plan to participate in the next closed training, so he agreed and completed the signing of the soul contract.

"The fourth round of the Slaughter Cup is the Library against the Jackalwere family. In the first round, I will win." Li Yue relaxed and finally announced the situation of the fourth round of the Slaughter Cup, like a prophecy.

Damen Benben was stunned—this is the Brain Spirit Lord? Facing the Jackalwere family, he will destroy them in one round?

"Recently, the Library will have an income, please be prepared." Li Yue needs to turn everything he wins into cash at the Vault before the Demon Market starts.

"…Okay." Damen Benben was still imagining how the Jackalwere family would be destroyed.

"Okay, take her and get out." Budiboge issued an eviction order, Damen Benben's chains swayed blankly, and he left with Nete Meier.

From beginning to end, Nete Meier didn't dare to say a word.
