I'm a monster in Demon King's Castle

It was a perfectly round and flawless “egg.”

The egg was silver, with a metallic feel, and surrounded by tiny particles that flowed back and forth, forming a bowl shape, then constantly combining into faces or skeletons, all in extremely bizarre forms; in the middle, Skorrlick's skull face even appeared faintly, leading Li Read to suspect that this “egg” could sense him.

As the small particles decomposed and combined, a sound close to a murmur echoed within the cavern, from ear-piercing cries to common demonic speech, as if it were calibrating its language.

What is this?

Is it a demon from another world, or even another era?

Li Read examined the “egg,” feeling an indescribable sense of strangeness—was this a complete entity? Or some kind of demon cub? Should he destroy it?

Can it be eaten?

[Consume 1 Demon Point to cancel the interdimensional transfer?]

When Li Read began to analyze the demon before him with the Demon Illustrated Handbook, he was suddenly startled by a line of text that popped up in his mind—he could transfer back?

And this 1 Demon Point was obtained just now by killing Budibog, and it was also Li Read's only accumulated Demon Point, which could be said to be very precious.

Since he could cancel the transfer, Li Read felt a little more confident, thinking that he might be able to communicate with this “egg,” perhaps saving his only 1 Demon Point…

Of course, even if he really wanted to transfer back, he would have to prepare in advance, lest he be as late as he was during the summoning, not only failing to use it as a shield but also leaving behind a small problem that had to be solved.

In any case, this “egg” could be considered an alien species, and it obviously couldn't just be left on the upper level of the library—Li Read analyzed it with the Demon Illustrated Handbook while pondering its disposal.

“What is this?” Shadow circled the egg, curiously touching the ever-changing particles, even stroking the silver eggshell.

“An egg, a demon's egg.” Li Read thought that if this egg were to suddenly attack, he would obviously need Shadow's help, so he briefly explained it to him, “Don't get too close, it might be dangerous.”

“Egg? Dangerous?” Shadow was startled, “Did you lay it?”

What was this operation? Fighting with Budibog while also laying an egg?

“It's from another world.” Li Read suppressed the turmoil in his heart, barely answering.

“You just went to another world?” Shadow was even more surprised—even though he was born in the Maw of the Abyss, he had heard about it from the demon expeditionary forces… how much magic it took to break through a spatial barrier.

Had this brain spirit unknowingly left him far behind?

If he had this level of magic power, directly pouring it into Budibog's body would be enough to blow up the Lord of Brain Spirits, right?

Or was it that this brain spirit, like him, greatly enjoyed the pleasure of battle?

Li Read had no time to pay attention to Shadow's inner thoughts, and it was difficult to explain to him, so he defaulted to it: “In short, it may be dangerous, do not touch it.”

Shadow hurriedly stepped aside.

Li Read analyzed the egg's composition while observing the strange particle flow, thinking that it was fortunate that the egg had not yet taken any other actions against him.

Sensing the spatial fragmentation in the core area, Li Read wanted to take the opportunity to look for any surviving forbidden books—the analysis progress was very slow, this egg was obviously not ordinary.

Unable to bear wasting time, Li Read used his mental power to wrap the silver egg, wanting to drag it along to take a look—no matter what it was, he would take it away first, and decide whether to send it back after the analysis was complete.

But just as he wanted to lift the egg, Li Read realized how heavy this egg was.

Like a mountain.

No matter how hard Li Read tried, with his current half-baked mental power, he couldn't move it even a tiny bit!

“What are you doing?” Shadow noticed Li Read's mental fluctuations.

Li Read pretended to be nonchalant: “I haven't decided… whether to send it back.”

Could it still be sent back? How many trump cards did this brain spirit still have?

Clearly exhausted, he could still break through space and send the egg back?

Shadow was in awe.

And so, a brain spirit and a shadow demon stared at the silver egg in the center of the cavern, not speaking to each other, as if thinking about whether to boil or fry the egg.

At the same time, in a chaotic space, the Demon King Mentor Mento also pushed aside the fog, watching the egg from afar.

“To actually be able to break through reality and summon…” Mento had of course been observing Li Read from beginning to end, and he was completely shocked by this—how many things did this brain spirit still have that he didn't know?

He could not only transform into various demon forms, but also read the minds of demons, and now he could even bring alien objects to break through space?

No wonder he had been evasive, seeming to be hiding many secrets…

Mento had lived for thousands of years, and even though he had seen a lot, he was shocked by Li Read's endless methods, and couldn't help but become even more excited—if this brain spirit became a Demon King, how much impact would it have on this world?

Could his wish finally be fulfilled?

Mento thought of the brain spirit's cautious yet reluctant attitude to help, and decided to temporarily not provoke him, continue to observe slowly, until the next time he fell asleep… then have a good talk with this brain spirit.

Moreover, the next “Advancement Studies” class seemed to have directly usable content—Mento stroked the scorched “Rebellion” card, pinched it between his fingers, and tucked it into his sleeve.

“Have you decided? Do you want to send it back?” Shadow waited for a long time, his patience finally running out.

Generally speaking, shadow demons are very patient, after all, most of them have spent thousands of years of solitude in their birthplace.

But this time was different—Shadow and Li Read had joined forces to kill Budibog, and then he saw Li Read put away the pituitary gland, then summon the alien egg, and then… he stopped moving?

This was too different from Shadow's expectations—for some reason, Shadow always felt that something else would happen.

“Haven't decided.” Li Read would of course wait for the analysis to be completed before making a decision—this was an alien demon, who knew what materials it would drop?

Moreover, Li Read suspected… that this was originally the intention of the Demon Illustrated Handbook to summon alien demons—the ecology and time state of a world are relatively fixed, and “summoning” alien demons is a supplementary means to enrich the Demon Illustrated Handbook.

He had to take advantage of the fact that this “egg” was relatively calm to fully complete its analysis.

However, up to now, the egg had not produced any malice against Li Read other than calibrating its voice and simulating forms with tiny particles, which was why Li Read had been waiting patiently until now.

“Do you have any suggestions?” Having nothing to do, Li Read asked Shadow.

“Me? I haven't eaten eggs.” Shadow had actually thought about this question, “But pure-blooded demons say that eggs are best eaten raw, no matter what the species.”

“Not eating.” Li Read didn't even have a mouth, and didn't have this need.

Moreover, Li Read also suspected that this “egg” was not a carbon-based lifeform at all—how could a carbon-based lifeform have such a mechanical feel on its skin, and be overweight in the egg stage?

“Like this, you go take a look at the core area…” Li Read, seeing that Shadow was idle, made a suggestion, and also told him his guess—the “little cloak” in the core area was the soul altar of the library, and the brain spirits would be resurrected from it at the beginning of each green time.

The remaining pages of the forbidden books should also be stored in the core area.

“Will Budibog be resurrected?” Shadow immediately perked up—recalling just now, Shadow was not satisfied with his performance of always paddling, and how much he hoped to have another performance like in the Blood River simulation battle.

Li Read let Shadow go to the core area to guard the corpse, not mentioning that when Budibog returned, he would no longer be the Lord of Brain Spirits, but only an ordinary brain spirit with fragmented memories.

Shadow left and never returned.

Just as Li Read was expecting to see the full state of the “egg” from the Demon Illustrated Handbook, the egg suddenly “spoke.”

“Hello?” The broken particles gathered around the egg, undulating and condensing into sound waves, standard demonic speech.
