67. Qualifications of a Successor (3)

“Are you… telling me to serve you at night?”

Aylin’s expression was the same as usual when she said that. But I noticed that Aylin was inwardly flustered.

Because when Aylin is flustered, she unconsciously grabs the hem of her maid uniform apron.

‘Come to think of it, I’ve been holding back from Aylin’s service lately.’

From the joint training to Cardinal Grius’s banquet. It was quite a strain, and there wasn’t enough free time to rest.

Moreover, the Devil’s Grimoire, Remegeton, has already been absorbed into my body. Because of Riel’s legacy, which is in the form of sheet music, I’ve been busy even in my dreams.

‘Even for me, I’m tired.’

If I don’t do it at all, I wouldn’t know. But once I start, I get too fired up.

My age is in its prime, and my stamina is excellent. And the heroines around me are so attractive that they make me squeeze out that stamina to the limit.

Recently, I’ve been holding back from her service again. My body is fine, but I held back for my sanity.

“No. I’m not telling you to serve me.”

“I see. I understand.”

Aylin let go of the hem of her skirt that she was unconsciously holding. Her expression is still the same, though. She seemed a little disappointed.

‘Aylin expresses her affection to me through service.’

Aylin always draws a line as a faithful maid. So she could only express her feelings that way. But Aylin, who hid her disappointment, continued.

“Then… why did you tell me to sleep in Young Master-nim’s room…”

“There’s a song I want to sing to you. If possible, I want to sing it directly in your ear.”

At those words, Aylin couldn’t hide her expression this time.

“Yes…? A song…”

Her cheeks flushed red.

[Hooh. Falling asleep while listening to a song sung by a lover is a romantic thing. Especially for a woman.]

As Erti said, I could feel what Aylin was thinking.

[But that maid is also pitiful. You are a person who is far from such romantic things. She misunderstood.]

Ignoring Erti, who was chattering, I climbed onto the bed. I had already finished preparing to sleep a long time ago.

“Aylin. Come up to the bed quickly.”

“Yes? Yes… I understand, Doryeon-nim.”

She had an expression that she didn’t know what I meant. Still, I could feel that Aylin was inwardly expecting something.

Because the quick-witted Sylph told me Aylin’s heartbeat. That intensified heartbeat was conveyed to my ears.

‘Hmm… this is troublesome.’

In fact, as Erti said. It wasn’t exactly for a romantic thing.

Actually, I have plenty of feelings for Aylin too. But right now, it was Remegeton. Opening that Devil’s Grimoire was the priority.

‘Stupid father. Why did you make that Devil’s Grimoire into sheet music of all things.’

I recalled memories of my past life after a long time. The name ‘Remegeton’ that I sometimes encountered in games or web novels.

A famous king who appears in history and the Old Testament. The Devil’s Grimoire, said to have been written by Solomon, that name was Remegeton.

Of course, it’s a separate item from that Grimoire. But since there is a commonality that it is a Grimoire for summoning devils. The game company did a good job of naming it.

‘Then you could have just given it to me as a normal Grimoire…’

That book, which was in the form of a Grimoire, was absorbed into my body as soon as the quest was over. And the contents of that Devil’s Grimoire remained in my head as sheet music-shaped memories.

Of course, my father committed more than one or two eccentricities. Even making that Devil’s Grimoire into sheet music like this seemed like something he would do.

‘He’s a crazy Demon King who pretended to be human and impregnated a Saintess.’

Anyway, all preparations were completed.

Aylin and I lay side by side on the bed. I had already changed into comfortable clothes to wear when sleeping. Aylin was still wearing her maid uniform, so I whispered in her ear.

“Aylin. You can change your clothes if you’re uncomfortable.”

“It’s okay, Doryeon-nim.”

I thought she was just like her. If she changed her clothes here. It would be difficult for Aylin to maintain her composure.

I hugged Aylin, who was turning her back without being able to face me, from behind.

She didn’t say anything. But soon her nape turned bright red.

She was already in a defenseless position, entrusting her body to me. Although she didn’t spray any separate perfume. Her sweet peach-like body odor stimulated my lust for a moment.

‘Hoo. It’s hard to hold back.’

But there’s something I need to do first right now. Stopping my hand that was unconsciously reaching for her chest, I said to Aylin.

“Then I’ll sing a song for you.”

Aylin nodded shyly.

---

I sang to Aylin exactly as the sheet music that came to mind.

It wasn’t ordinary sheet music. Clearly, I would be able to make contact with devils, especially Archdevils, through the music contained in this sheet music.

‘Cecilia failed to contract with an Archdevil… I can’t do that.’

Lucifiel’s legacy to prevent that failure is this Remegeton. So I had to open this Grimoire quickly.

‘So I’ve been practicing singing according to this sheet music diligently for the past few days.’

However, Remegeton was not opened just by me singing that song alone.

Riel was a genius minstrel. Perhaps this Grimoire doesn’t recognize my singing skills.

“How was my song, Aylin?”

“Well… that’s…”

Aylin couldn’t answer easily. She became a sacred priestess of Hesus, the god of art.

In addition, Aylin, who is blessed by that god. Aylin was the person who would evaluate my song more coldly than anyone else.

[Hoo… I can’t bear to listen to it. Your face resembles Riel’s, but your singing skills don’t even come close to his toenails.]

Aylin’s reaction was the same as Erti’s. I tried to take a peek at Aylin’s expression, but Aylin turned her body and completely curled up.

[Do you have to see it to know? That faithful maid can’t control her expression because of your song.]

[Was it that serious? Maybe there’s a problem with the sheet music, not me?]

[The song Riel made is considered the most high-level song in Isrand’s music history. There’s no way Riel would make a sloppy song, right?]

Erti was right. If there was a problem, it was on my side.

‘Damn father. Why did you leave your legacy in this way…’

But I knew this would happen. So I bothered to call Aylin to the bed.

‘If I can’t sing this song. Aylin can sing it instead.’

As long as Remegeton is in the form of sheet music. Anyone other than me could sing it.

But Remegeton is literally a Devil’s Grimoire. If someone who doesn’t have the qualifications touches that sheet music carelessly. I didn’t know what dangerous things would happen.

And as long as the ownership of Remegeton is with me. Even if Aylin sings that song perfectly. There was a good chance that this Grimoire would not recognize it.

‘Of course, I’ve thought of everything.’

With the ownership remaining with me. A way to make even the song Aylin sings my work. I thought I knew that method.

I hugged Aylin more gently.

“Cecilia and Tricia deciphered all the sheet music my father left behind. So they tried to sing that song to me, but it’s not easy.”

“Ah, no. It’s a good enough song…”

“There’s no need to say flattering words. I know my singing skills.”

“There’s no need to blame yourself so much… Ah, then…”

As expected of Aylin, a faithful maid. She said to me.

“If you show me that sheet music, I’m not enough… but I’ll sing the song to Doryeon-nim myself. I’ve done that before…”

“No. As soon as I deciphered that sheet music, it caught fire and disappeared. Perhaps it was a legacy my father left directly to me. He didn’t want to show it to anyone else.”

“Then… I’ll just follow what Doryeon-nim sang a little while ago…”

Aylin lightly hummed and tried to sing along to the song I sang. But it didn’t work out as Aylin intended.

“Why… why the song?”

“Perhaps he composed the song so that no one else can sing along.”

“There’s no way such a thing is possible…”

“No. It’s not necessarily impossible. I asked you just in case. As expected of that epithet, my father seems to have played tricks on his legacy.”

“The Devil’s Minstrel Riel… Ah! I’m sorry. I was rude to Doryeon-nim’s father…”

“No. Rather, that would be the correct answer. Unlike my mother, Agnes-nim. My father is a person whose identity is unknown.”

“That’s…”

Aylin was silent for a moment. I knew the reason.

‘I shouldn’t have mentioned Riel’s name at the Margrave’s mansion.’

A precious only daughter. In addition, he was an irresponsible man who impregnated Agnes, who became a Saintess, and disappeared.

In particular, Margrave Wilhelm hated him so much that Riel was treated as a non-existent person in the Reinhardt family.

“Anyway, it’s a shame. I thought you, Aylin, would be able to sing along. I’m saying again that I know my singing skills are terrible. It would have been better if you sang it.”

“I’m sorry… Doryeon-nim.”

“No. There’s no need for you to be sorry. The fault lies with that irresponsible man. Well, if it’s a legacy left only to me in his own way, I can’t blame him.”

Aylin was silent. She didn’t do anything wrong. But as expected of Aylin’s faithful personality, she seemed to feel sorry for me.

And that’s what I wanted.

‘I feel a little sorry for using Aylin. But in the end, it won’t be a bad thing for her either.’

I casually said to Aylin.

“It’s late. So it’s better to fall asleep quickly like this. Maybe I can hear the song of your father singing in my dreams.”

“In a dream… you mean. Well. There’s a saying that if you desperately want it, it will come out even in your dreams…”

“There’s no need to be so serious. I’m just saying it. Let’s fall asleep quickly.”

I fell asleep while hugging Aylin as it was.

---

I was in a dream now.

But even if it was a dream, there was no difference from reality. The current dream is a lucid dream. I created this dream with the power of a succubus.

“Then what I have to do is. Wait for Aylin to fall completely asleep.”

I made a comfortable chair and leaned back on it. Seeing that Aylin wasn’t coming here soon. It seemed like she couldn’t fall asleep easily.

‘Well… it might be a little embarrassing for Aylin.’

It’s not like we’re exhausted from sharing love and falling asleep. It’s like she’s being hugged tightly by me like a lover.

And it’s actually impossible for Aylin, who is not a succubus or a magician, to enter my dream recklessly. But I put a suggestion on Aylin for that.

‘If it’s the faithful Aylin. She’ll really want to sing a song for me even in her dreams.’

Because of that intense desire, my dream and her dream will be connected. Using this method, I could invite Aylin to my dream.

“Then I can release Remegeton.”

As I talked to Aylin. Remegeton was a legacy that Lucifiel left only for me.

But even that Demon King didn’t seem to have predicted his son’s artistic talent in advance.

‘Well. Remegeton will be opened just by singing in tune and rhythm. I’m not doing that easy thing.’

So I had to get Aylin’s help, even though it was troublesome like now. If I enter her dream with the succubus trait and release Remegeton. It’s useless.

‘It’s only possible in my dream. Not anyone’s dream.’

The current lucid dream is a space that I own entirely.

If Aylin comes into this place. It will be possible to release that Devil’s Grimoire by singing a song.

‘And as long as it’s my dream. It will be judged that I opened that Grimoire.’

Also, there was one more thing I had to check. The Yin Gate that Carmen and Lucia created after their relationship with me.

If Aylin also has that Yin Gate. Perhaps I can minimize the backlash or side effects of releasing Remegeton.

‘But it’s not easy to create a Yin Gate in reality for a very faithful personality like Aylin.’

That heart alone, that she will give everything to me, cannot create a perfect Yin Gate.

Along with that heart, there must be a desire to possess me. Only when that desire is together will the power of the Yin Gate become stronger.

‘Then it would be good to give Aylin the perfect love she wants in this dream.’

Perfect love that can release all her desires. Only that love will be able to create a Yin Gate for Aylin.

The moment I finished organizing all my thoughts. Finally, Aylin entered my dream.
