I'm a monster in Demon King's Castle

Now, Li Yue truly mastered this bone sword, and only then did he realize how lucky he was to have killed Scollerick back then—the bone sword sealed three high-level demon-level abilities. If Scollerick had managed to use any one of them at that time, the one who died would not have been the Skeleton Prince, but the No. 7 Brain Spirit of the Fifth Repository.

Vacant Authority, Withered Thorn, Dirge of the Dead.

Vacant Authority came from the Skeleton King Liddrick, and it was a token of the "Grave of Light" in the underground area of ​​the Demon King City. It was the grave of all the "light" that shone on the Demon King City, and it was also the burial place of various demons, inhabited by a large number of undead demons, such as ghouls, zombies…

The Vacant Authority is the authority of the Skeleton King. As long as it does not violate the will of the real Skeleton King, when Liddrick is not around, the demon who masters this bone sword is equivalent to the Skeleton King himself in terms of rank.

The skeletons of Demon King City and the undead demons in the Grave of Light… must obey the will of the holder, and can be immune to most undead magic damage.

Withered Thorn is a powerful attack that extracts the holder's magic power and transforms it into the "Withered" attribute—Li Yue has not yet experimented with the specific effect, but with the Brain Spirit's magic power reserves, it can only be used once a day.

Dirge of the Dead is a range spell that does not require the holder's magic power to be consumed, but directly summons unowned vengeful souls from the realm of the dead. The specific effect is not fixed, but combined with the Vacant Authority, it can be understood as a range-based attack magic, with the possibility of causing enemies to be slowed, confused, driven mad, or even killed.

With these three abilities, Li Yue's tactical space has been greatly enriched. A bloody plan gradually took shape in his mind. The biggest variable was not Bosh and his lackeys, but Mento's blessing.

Taking the "Dirge of the Dead" as an example, once it takes effect with "Reversal," the scene may become extremely out of control.

However, this point is difficult to avoid. Mento's blessing has advantages and disadvantages. It is impossible to only enjoy the benefits of "Absorption"—perhaps this is the result of bargaining with the demon.

In addition, Li Yue vaguely sensed from the bone sword that after becoming a sensing object, it could no longer harm his Brain Spirit body; and… it was not only a weapon, but also a key.

It's just that Li Yue couldn't judge for the time being what kind of door it could open—tsk, there wasn't even a map or anything.

The Demon King City is so big, which door will this bone sword open? The Grave of Light? Or what?

What's inside? Maybe Scollerick's entire fortune?

As the Skeleton Prince, Scollerick can't just have a bone sword as a treasure, right?

After carefully investigating with his mind for a moment, Li Yue still couldn't find out the specific location of the "door", and could only hope that if he really stood in front of that door one day, the bone sword could give a hint.

"Is Bosh going to die?" Yingying interrupted Li Yue's thoughts and talked about Li Yue's immediate crisis.

"With your and my current state, it is no different from being sent to his mouth as meat, and the kind that has no chewiness at all." Yingying gave a pertinent evaluation of the current state of the two demons.

"Of course, we have to rest first…" Li Yue kept improving the plan, and at the same time tried his best to calm down, and eliminated the sequelae of just soaking in the bone sword through meditation.

At this moment, let alone using the bone sword to subdue the enemy, even manipulating the skeleton was a problem for Li Yue.

"What about after the rest? How to kill? I'll help you control Nete Meille, Mai Mai, and them, then what?" Yingying was a little anxious for Li Yue, "Bosh and the three of them are still waiting for you outside…"

"Don't worry… I'm not worried, why are you worried? This is not a duel, but a war of attrition. It is impossible to eliminate Bosh and the three of them plus Finley all at once… so there must be killing and stopping, and find a good rhythm…" Li Yue said, while also combining the new abilities obtained from the bone sword to sort out his thoughts.

The outside of the library is very large, and there is a lot of room for display, and the scene is also very large—Li Yue's initial idea was to include the Brain Spirit, Mini Mini, the Book Demon… and even Budibogg, killing them upside down and making them restless.

During the meditation, Li Yue outlined a map of the library in his mind, Brain Spirit, Mini Mini, Book Demon, Budibogg… even Finley could be a chess piece—as long as it is placed in the correct position, it can be crushed.

In endless trial and error, Li Yue was looking for the possibility of a "comeback", and the plan gradually became fuller—although it was full of dangerous moves, but relying on the "Stealth" and "Withered Thorn" and other trump cards, Li Yue felt that it was almost time, and he could give it a try.

The details of the plan are not as valuable as the framework of the plan. Li Yue firmly remembered the key points, and finally adjusted his state—Yingying would never have thought that this time he went out of the mountain, he would bring such a terrible plan…

"How long have we been here? Have you counted?" Li Yue devoted himself wholeheartedly, and had long forgotten the years in the room, and even didn't know that he had opened up his subconscious mind in the process of promotion, which made Yingying even more impressed.

【This Brain Spirit seems to be very ambitious… This Brain Spirit is very valuable…】

Can he be used? Li Yue thought that Yingying was thinking about this.

"You asked me how long I've been here? How would I know? Is there moonlight here?" Yingying answered Li Yue's previous question—Shadow Demons calculate time through changes in light, and at this moment, she was also at a loss.

However, just as Li Yue asked this question, the candlesticks in the stone room suddenly went out, and the confinement ended.

…

In the entertainment room, Bosh and Keli and Ke'er were still in those small bodies, swimming in the air looking for any signs of trouble. Bosh's eyes were dark, but there was still a trace of joy on the corner of his mouth and his eyes were hot. Obviously, he had been entangled with Nete Meille for a long time, and his body and spirit had reached another peak of fanaticism.

The demon merchant Mai Mai's fat body was pressed on the sofa not far away, one hand covering the huge necklace on his neck, and the other hand curling his fingers in a cycle, admiring the colorful rings; the nightmare demon Nete Meille was hanging upside down on the crystal lamp on the ceiling, her face flushed and lazy, as if she thought the light was too bright and the taste in the entertainment room was too light.

The surviving Mini Mini had already put on armor. At this moment, their eyes were dull as if they had fallen into a dream. In addition to the knives and swords "traded" from Mai Mai, each of them had an extra gem on their arms. I don't know what kind of action they were brewing.

The crystal chandelier shone brightly, and Scollerick suddenly appeared under the lamp, with the bone sword in his hand and a look of vigilance.

But at the same time, the three demons of Bosh discovered the trace of the skeleton. With just one lift of their hands, countless brilliance smashed over—Mini Mini's arms stretched out like lightning, and under the blessing of the gems, the knives and swords in their hands emitted brilliance, like an inverted supernova explosion, instantly gathering in the area where the skeleton was located.

Clang!

The sound of space breaking rang out. There was not a single dead corner. The area where Scollerick was located was like a cracked mirror. Each attack pierced out new cracks, only hitting Scollerick's bones inch by inch, and then irregularly falling on the carpet.

But the attack did not stop there—the brilliance on their arms infected their whole bodies, and the gray-faced Mini Mini screamed and rushed up, grabbing the broken bones all over the ground and stuffing them into their throats.

Wrapped in brilliance, the bones seemed to be eroded into the most delicious cheese, and were soon devoured by the Mini Mini.

The sound of bones breaking continued to weaken. Halfway through chewing, the Mini Mini vomited wildly, vomiting so much that even their bodies changed shape!

But they could only spit out turbid mist, and then rolled their eyes in the dislocation of their muscles and bones, and fell into a daze again—as for Scollerick's bones… there was not a single bit left.

"Go to hell, skeleton… die…" Bosh gritted his teeth, and then a hot breath blew away the turbid mist that the Mini Mini spit out.

"Then… what if the Skeleton King investigates…" The demon merchant was still not very relieved and hesitated to speak.

"The Skeleton King Liddrick is sleeping in 'Dreamland'. Maybe it will be thousands of years before he comes out…" Nete Meille smiled triumphantly, "Even the Demon King… as long as he enters 'Dreamland', it is difficult to come out by his own will before the time comes~"

The people in the entertainment room were immersed in the joy of killing Scollerick when suddenly the crystal chandelier on the ceiling lit up again, and they just remembered that there was another trainee who had also been confined.

Yingying came back, half a beat slower than Li Yue.

A ball of shadows was lying beside Mini Mini, circling around the shadows of the little guys one by one. After the creaking sound of bones, the Mini Mini finally bid farewell to the deformity of their bodies and returned to normal.

"Scollerick is already dead, do you want to go with him?" Bosh looked at the wriggling shadow under Mini Mini.

"Pfft…" Yingying seemed to have heard a funny joke, and the faint shadow trembled into a ball.

And beside that faint shadow, a stain-like shadow was hanging extremely unnaturally under the sofa, arousing Bosh's curiosity even more.

That stain-like shadow was Li Yue—he had already included the Shadow Demon in the Blood River. Li Yue could become like Yingying, and he also "transformed" as soon as he teleported back to the entertainment room.

It's just that Li Yue couldn't control this body as freely as Yingying, and coupled with the huge mental energy consumption in the confinement room, Li Yue had no choice but to release a skeleton to attract firepower first…

Of course, it would be best if he could deceive Bosh and the others, so that he could completely turn to the dark.

"The skeleton is not dead!" Bosh's demon intuition pierced into his mind like a thorn. After seeing Yingying's unnatural performance, he immediately realized that things were not developing as he had expected.

When several pairs of eyes fell on that stain-like shadow, several malicious prompts popped up in his mind. Li Yue did not hesitate and directly chose "Stealth."

That stain was quietly erased, and no one could sense Li Yue's existence anymore.
