Chapter 13 – A Man and a Woman Who Gain Magic When They Do Naughty Things (Crystal) #3

As soon as I opened my eyes in the morning, I read the magic book and started practicing hand seals.

‘If it was like the old days, I would have just taken a nap until noon.’

After getting my hands on the magic book, my destructive lifestyle changed.
The old me lived a lazy life as an incubus, a trash race.
I didn’t live very hard because I was stuck with a sense of defeat like ‘I can’t do anything because I’m an incubus’.
But the chance to learn magic gave me hope.
Maybe I can escape the damn bottom life too? It is hope that
Motivation to practice magic with all one’s strength is working properly.
Of course, you can’t starve to death while only practicing magic.
In the afternoon, he planned to go to the Adventurer’s Guild to find a new request.
However, as time passed and they were about to depart for the guild building, they had a reason to cancel the plan.
It was because a familiar guest came to the inn room.

Smart!
An urgent knocking sound.

“Luke. He’s inside! Hurry up and open the door!”
“Rebecca?”

When I opened the door, I met eyes with a red-haired female swordsman standing in the hallway of the inn.
Rebecca, who had parted coolly last night, reappeared.
I thought we would never meet again.

“Bar, can I go into the room?”
“Did you leave anything behind yesterday?”
“No, that’s not it… I have something I really want to ask you. Please give me some time..”
“For a moment, it doesn’t matter.”

Even if you tell them not to come in, they will forcefully push you in.
I gladly allowed Rebecca to come into her room.
Soon after, Rebecca knelt on the floor in her room and explained what had brought me back.

“Something strange happened to my body today.”

Could it be because of pheromones?
Is your body still in heat and you still feel dirty?
I don’t think I’m particularly excited about that.

“Don’t be shy and tell me quickly. What’s strange?”
“You know what mana is? First of all, you’re a wizard. You must have learned how to feel mana.”
“Of course.”
“I also learned how to feel mana from my master. Unlike you, I learned how to practice swordsmanship.”

Of course, I must have learned how to feel mana.
Rebecca’s teacher would be a swordsman, that is, a sword master, but he couldn’t have taught his pupil how to respond to mana.

“Now I realized, the mana in my body has increased. It’s great.”
“That’s a good thing. Should I congratulate you?”

I see Rebecca talking about the increase in mana with a very happy expression.
I clapped because I thought I needed a reaction.

“Awesome. Very awesome. Rebecca-sama’s mana increased. I also increased my mana while training this morning. Congratulations.”
“It’s different with you.”

What is the difference between circumstances?
The increase in mana is a natural phenomenon.
It is common sense that wizards get mana by training magic, and martial artists get mana by training martial arts.
Last night, fighting Lawton’s gang, she must have accumulated mana thanks to her actual battle.
Even I, who had no relationship with Mana, knew this level of common sense.

“My body is constitutionally incapable of accumulating mana.”
“What?”

However, after hearing the following words, she changed her mind.

“Because the nerves that accept mana are broken. It is impossible to accumulate new mana other than the mana you have had since birth.”
“Is it a peculiar constitution?”
“It’s like that. There is a special organ in the human brain that controls mana, and the more developed the organ, the easier it is to feel mana. But the nerves in my head are only half that.”

Rebecca raised her finger and tapped her forehead.

“It is possible to feel mana, but it is impossible to accumulate mana. The brain refuses to accept outside mana into the body. So I am destined to never increase mana for the rest of my life. Even if I swing my sword enough to break my wrist, That means you can’t become strong as a warrior.”
“Hmm…”

I didn’t fully understand what you meant.
It’s the first time I’ve heard of a brain organ that controls mana.
However, I understand that Rebecca is originally a peculiar constitution that cannot accumulate mana.

“My mana, which hadn’t increased even after training all my life, suddenly increased today. It didn’t change at all when I came back after completing the request. Then there’s only one thing I can think of. Something happened between us last night.”

Was there something
All I did with him last night was drinking, fighting outside, and having an accident because of pheromones.

“Did your mana increase while drinking? Or that you woke up while giving fists to the beastmen.”
“I don’t think it’s either. Even when I was in my hometown, I drank well and punched a lot.”

It’s a life of drinking and punching a lot.
You’ve had a pretty rough life, Rebecca.
Are you Doo-Han Kim of the Kingdom of Jakarta?

“I’m telling you in case you misunderstand me, but I had a reason to get hit by all the fanboys. Most of them started fighting with me first. I’m not a bully who runs after anyone.”
“That’s right.”
“Why are you using honorifics all of a sudden?”

Momentarily, Rebecca gave off an Iljin woman force, so I was scared.
I quickly changed the topic, scratching my cheek.

“Maybe the incubus pheromones stimulated the brain.”
“Pheromone?”
“Aside from everything else, there’s only pheromones. Didn’t something happen to your brain during the 20 minutes you were enchanted by pheromones yesterday and went into heat?”

I don’t know too well, but I just said what came to mind.

“Maybe you’ll find out if you use pheromones on your body again. What does pheromones have to do with changes in you?”
“That, to have such an embarrassing experience again…”

Rebecca shook her head, mumbling at my suggestion to take her pheromones again.
It’s understandable to be hesitant to sniff pheromones and force them into heat.
It must feel like torture to remain in heat without being able to reach your peak.
I got an erection while watching fucking porn, but wouldn’t it be painful if it was impossible to take off one leg?
If you don’t like it, there’s no reason to use pheromones.
Instead, I, a second-year resident of Joensuu, thought of another method.

“Let’s go to the library.”

I said while supporting my chin with my thumb and forefinger.
I think it’s a pretty cool pose.

“If you have any questions, you can go to the library. There you can find out everything except what is not in the books. Isn’t it really amazing and mysterious?”
“You say things for granted while keeping your form.”
“Maybe I can get some form. Anyway, there’s a big library in Yoensuu. The lord of this town is a terrible bookworm, so he built it with tax money. Let’s go and look through all the books about the incubus.”
“Okay.”

Rebecca nodded her head eagerly.
Even if I stay still, the question won’t be solved anyway.
In this medieval land, the library is the surest place to get new knowledge.
In fact, since I was reincarnated, most of my knowledge about this world has been accumulated through books.

“Thank you for thinking with me. I’ll have another drink later.”
“Can I order food more expensive than 10 coppers then?”
“Yes. You can empty my wallet and eat something delicious.”
“Haha, that’s fucking good.”

*

Joensuu Municipal Library.
It was the place where Rebecca and I had arrived after leaving the inn.

“You’ll have to read a book about the incubus. Go through the books on the bookshelf over there.”

Going into the library, Rebecca and I randomly gathered books related to the Incubus.
After a while we sat across from each other and began serious reading.
Of course, you don’t have to read all the books you picked out from cover to cover.
All we want to know is the connection between the incubus’ psychic powers and mana.
You only need to focus on the part where Mana is mentioned.

“No?”
“Not here either.”

I checked most of the books piled up like a mountain, but there was no special result. Time passed and I brought a new book from the bookshelf, but I couldn’t find the information I was looking for.

A case in which the mana of a woman possessed by an incubus increases.
I just wanted to find one among the countless books. Only useless knowledge has increased.
Like the knowledge of the 48 position developed by Incubus.
I was almost taken aback by the bad illustrations.

“After…”

The investigation failed.
After checking the last book, Rebecca let out a sigh of regret.

“I can’t help it when this happens. I’ll have to take another look at your pheromones.”
“Didn’t you say you didn’t like it earlier?”
“But there’s no way. Rather than holding on to you, I’d rather drink some cool pheromone and check it out.”
“I like it because it’s like a gifted woman.”
“What’s a bonus woman? Anyway, let’s get out of here. Go into something that looks like an inn and shoot me a pheromone.”

Eventually, after much thought, Rebecca chose to take on pheromones once again.
Judging from the fact that she chooses the path of the horny girl that she hated so much, it seems that she has a fairly strong obsession with mana.
Well, that’s a lot faster than going through a book.
But there is only one book left to read.

“Wait for a sec.”
“Yes?”
“There’s something I want to check. There’s a book I haven’t read yet. Wait here.”
“Yes, bring it or-“

Rebecca let me go without any expectations.
I quickly took out a book from the library.
This is a book that I have been looking for every time I go to the library.
I thought I should read it someday when I have time, but I didn’t know it would be today.

〈 Origin of the Incubus 〉.

It was the title of the book I chose.
As she returns with the book, Rebecca sees the thickness of her book and opens her eyes wide.

“Oh, it’s a very thick book. If you hit it with a corner, people will die.”
“As thick as it is, I can’t get anything out of it.”

I was thinking of ending my last investigation with this.
Me and Rebecca sat down and looked through a book together.

“Quickly pass it on. I want to go out and finish it with pheromones.”
“Yes, yes.”

I told Rebecca that I would read it quickly, but in fact she had no intention of skimming it.
〈 Origin of the Incubus 〉 is a book I’ve been wanting to read for a long time.
I thought I should read it every time I came to the library, but I hesitated to read it because it was so large.
I started reading it carefully, starting from the front.

– Incubus is originally a demon born in a dream. In a completely different dimension from this world, there is a dream world called DreamLand, where the incubus were originally residents.

– The female residents of Dreamland called themselves Succubus, while the male residents called themselves Incubus. Both the succubus and the incubus are treated as the same dream horse, but in this text, the male dream horse, the incubus, will be dealt with in detail.

“This is another novel story. My race was born in a dream?”

Only a fantasy-like story about the birth of a species.
Is it normal because it’s a different world?
All young children on the continent are receiving home education as a fantasy.

– It is unknown why the Dreamers abandoned Dreamland and crossed over to the continent. However, according to the records of the old books, one interesting hypothesis can be established.

– The different races of the continent who enter the dream world through sleep every night. The ancient dreamer clan ate heterogeneous tribes by questioning and answering questions, but from a certain point on, they could no longer be satisfied with only dream sex. The dreamer clan wanted to be impaled and impaled by living creatures.

“Hemmy, Sifal…”

Suddenly, the contents of the main text are interesting to read.
It was because every page had a fucking raunchy illustration.
A succubus swaying on a ride while making ahegao,
Like dream demons mingling together and chewing as a group.
Is it possible to play anything because it’s a dream?
In the illustration, there was even a scene where a woman was poked through by an incubus that had turned into tentacles.
If this wasn’t a public place, I’d already pulled one.
Are you a dreamer who knows a little about tentacle play?

“Huh…!”

I looked at the illustration for a long time and was surprised.
It was because Rebecca poked me in the side in the seat next to me.

“Bye, you pervert-! Why are you staring at a painting like that!”
“Calm down. Illustrations are pictures to help understand the main text. If you look closely at the illustrations, you can understand the book more deeply.”
“What do people do when they see it here?”
“Is it time to pay attention to what others are staring at? What if I miss something while reading it roughly? Shouldn’t I read it thoroughly because it’s the last survey?”
“Anyway, you’re good at talking, Hoo.”

Rebecca had her face covered with the palm of her hand at an obscene painting that appeared out of nowhere.
However, the fact that she glanced at the book through the cracks of her fingers suggests that she also has some level of curiosity about sex.

“Hick.”

It is very cute to see a surprised reaction whenever you see an illustration full of abnormal sexual desire.
I continued reading through the book.
In the book, the incubus’ hypertrophied libido was explained.
As Rebecca studied the book beside her, she gradually realized the identity of her people.

“Your species are very open-minded. It’s the dreamer tribal custom to wean off virginity before the age of 10. I think I’m going a little crazy. I feel like my common sense is twisted.”

In the book, I was able to find out various characteristics of Incubus that I did not know.
Of course, all of them are vulgar characteristics, so there is no point in explaining them with words.

“Ah, I found it.”

It was a time when I was endlessly turning the pages of books with my fingers.
Near the end of the book, Rebecca and I found the information we were looking for.

– Very rarely, there are cases where women who mix their bodies with an incubus experience a special phenomenon. It is a phenomenon in which mana increases in the body.

“As expected, my prediction was correct.”
“Yeah, was it really there? Is it really because you’re an incubus that your mana increased?”

As soon as that passage came out, Rebecca’s eyes changed.
Rebecca opened her eyes wide and began to read her book with concentration.

– This amazing and mysterious phenomenon begins when an incubus meets a woman who is compatible with him. The compatibility here is the compatibility between the incubus and the woman’s mana. When the waves emitted by each other’s mana are in perfect harmony, the incubus’ body undergoes tremendous changes.

– At that moment, the incubus acquires the properties of a conductor that is easy for mana to pass through. At the same time as sucking nature’s mana into its body, it shoots it towards its partner. As a result, incubus and partners can enjoy the effect of increased mana after sleeping.

“Oh my god…!”

Rebecca looked surprised as she read the book.
Of course, I was also surprised.
To think that the incubus, who was only thought to be lascivious, had such an amazing ability.
It is an ability that strengthens the partner by transforming into a conductor that can easily accept mana.

– An incubus that has become a mana conductor is said to have reached a ‘trance state’ in the academic world. However, cases of finding an incubus in a trance state are extremely rare. In order for an incubus to transform, he must first meet a woman whose mana wavelength perfectly matches, but the probability is so low that it converges to zero.

After reading the book to the end, I realized why Incubus’ ability was not widely used.
It is simply a matter of probability.
It was very difficult to find a partner with perfect mana compatibility.
Moreover, it is said that it was impossible to make the incubus a conductor in any other way no matter what the scholars went through.
Rebecca asked me with her whitened face.

“So, to sum it up, you and I are good at it, right?”
“That’s right. It’s not only compatibility with the inner world, but compatibility with mana is also good. The two of us are meant to be matched in nature. We can accumulate mana just by continuing to do lewd things.”
“Nonsense…”

Rebecca looked up at her ceiling and gave her a puzzled look.
Either way, I raised my hand and felt my belly.

In the book, not only the partner, but also the incubus who entered a trance state can enjoy the mana amplification effect.
In fact, I didn’t even know my mana had increased until now.
It wasn’t long before I learned how to feel mana, so I wasn’t conscious of mana normally.

However, when I checked the sensations in my abdomen, I could see that the mana in my body had increased a little.
A small amount of mana that can be acquired by practicing magic.

“The mana I acquired last night isn’t that much.”
“You mean the efficiency is bad?”
“It’s too early to say it’s bad. We were just hanging out last night in our horns, but we didn’t do anything ‘really dirty’. No petting or penetration.”
“That’s right?”
“I didn’t do anything while in heat, but I got mana similar to training magic. Doing ‘really naughty things’ seems to be much more efficient than training magic. If you use the trance state well, you can get mana several times faster than others. Could I build it?”
“…Ah.”

Rebecca let out a sigh full of her anguish as she clutched her head.
Because of her constitution, it was impossible to accumulate mana throughout her life, but she found the only way to acquire her mana.
But that way is to do naughty things.
And that’s with some lewd-looking incubus.
Putting the book back, I said to Rebecca.

“Let’s go out and talk. Let’s make a decision calmly while getting some fresh air.”
“Yes.”

I took the confused Rebecca out of her library.

*

There is a small garden outside the library building.
Flowers were in full bloom in the garden maintained by the library’s staff.
There weren’t many people around, so Rebecca and I decided to chat in the garden.

“So, have you made your decision? Rebecca.”
“What, what decision…?”
“Didn’t you need a way to get mana? You said you couldn’t accumulate mana in normal ways because your cranial nerves were broken. Would you like to stick around with me and do ‘slutty things’?”

An incubus that enters a trance state increases the mana of its partner.
It seems that this kind of mana is forcibly injected into the body, ignoring the will of the partner.
It means that mana accumulates in Rebecca’s body whether or not the brain rejects external mana.

“I want to build up mana, but-.”

Rebecca looked at me with a hesitant expression.

“It’s a little bit of entrusting my body to a man I don’t know well… I learned in my hometown that you should always be careful with your appearance.”

What stood in her way was her purity ritual in her native kingdom of Jakarta.
You must not defile your body recklessly with an outsider.
Her consciousness, which she has been taught since she was a child, is suppressing her Rebecca’s desires.

“What’s up? This isn’t your hometown. There are more skinny girls on this continent than I thought.”
“…”
“It was luck that we met. In the book, it is said that it is rare for an incubus to meet a woman who is compatible with mana. A miracle like this will not happen again.”
“That’s not enough! I’m not even a maid selling my body on the street. I want to get mana, but there’s a line that needs to be followed…”

Rebecca still couldn’t let go of her hesitation.
Watching her fidgeting with her fingers made her twitch.

That’s if you’re honest about it.
After reading 〈 Origin of the Incubus 〉, Rebecca became obsessed.
She can get mana just by doing naughty things.
It’s a creative economy that creates something out of nothing.
Besides, I had another reason not to miss Rebecca.

‘If you want to do naughty things, you’ll have to stick together. Then Rebecca will become a regular member of the party with me. Because there are party quests in the Adventurer’s Guild that can be done with two people. If I move with him, the number of requests I can receive increases.’

As an adventurer, this was a genius opportunity.
It would be unimaginable for an incubus adventurer like me to have a fixed party.
If Rebecca was together, that moment was the birth of a two-in-pot adventurer.
I don’t need to explain that a duo is 100 times better than a solang warrior.
I never wanted to miss Rebecca.
Therefore, she worked hard on her head and gave her persuasion.

“Rebecca, is it because you don’t trust me that you’re hesitating? You can’t commit yourself to a man you don’t even know.”
“Yeah, right? Working the night together is only after understanding each other deeply.”
“Then, how about this? For a certain period of time, the two of us will have time to accept each other.
“You mean the sum…?”
“When the period is over, if you don’t like me, you can leave right away.

From here, it seemed that force was needed.

Widely-!
Suddenly, I grabbed Rebecca’s shoulder.
After holding her shoulders tight to keep her from backing down, he opened her mouth with her manly vigor.

“Ugh! What are these hands!”
“Let’s make a fixed party with me, Rebecca.”

It’s like proposing to the girl you really like.
If you change the word ‘fixed party’ to ‘baby’, isn’t it a perfect confession?
I feel a little embarrassed.

“Oh, a fixed party?”
“Let’s go together for a month when you complete the quest. Actually, don’t you need someone by your side to explain this and that? There are a lot of things you don’t know since you’re a first-time adventurer. If it were me, I could teach you everything from one to ten.”
“…Ugh.”

Rebecca was in a state where her ear lobe was red from the sudden body touch.
I can’t find a place to put my eyes on, as if I’m not immune to men who openly attack me.
I can see tears forming on Rebecca’s face.

After a moment of silence,
Finally Rebecca opened her mouth.

“Ah, I understand! I understand! So let go of this hand! Please…!”
“Really? Are you having a fixed party with me?”
“Yes, yes! I’ll fix it or whatever! Please release it now…”

Success!
Rebecca accepted the fixed pot offer!
I felt a tingling sensation all over my body and raised my arms and let out a cheer.

“Yeah!”

Finally this day has come!
Luke, a lone solange warrior who wandered the continent of Midgard.
Finally Escape Solange and start a happy duo!
After entering the adventurer industry, I got a fixed pot in about 720 days!

“Give me a toast!!”

I danced a bean dance of joy in the middle of the garden.
He hummed the melody of Pocheongcheon and shook his whole body.
Because from today, I am not number 1, but number 2.
I tried to express my joy with a bean dance that matches the number.

Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam.
Ground ground.
Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam Bam.

Please take good care of me, Rebecca, who excels in martial arts.
