Being Able to Edit Skills in Another World, I Gained OP Waifus

Chapter 88: The ‘4 Concept Cheat Skills’ Had A Safeguard On Them

The entrance to the cave was hidden by tall trees.

According to Rafilia’s (vague) memory, the cave was also built as part of the Valley of Mist. Its purpose was for the “welfare” of the Ancient Elves and Demons who were involved in the creation of the valley. It was a restroom that absorbed the mana of the surrounding and kept itself clean.

However it was not as amazing as the Valley of Mist. The rooms just got a little warmer when you pour mana into them, and the cave had tricks to keep monsters away. It was difficult to find and there was also a bathing cave a little higher up the mountain as an accessory facility.

‘We are just going to spend the night, though.’

Rafilia explained with a smug look on her face, “The main Valley of Mist has collapsed, so it will eventually lose its function and become just a cave.”

I checked inside, but the cave was just a passage with a few small rooms. There were no relics, no magic tools, nothing. It was totally empty.

The only thing I got out of it was the murals of the Heavenly Dragon.

There were three pictures on the wall. One was of a pure white Dragon with its wings spread out soaring through the sky, the other was of the same Dragon turning into a platinum blonde girl, and the third was of the Dragon falling after her wings were cut off.

Underneath the last picture was a huge weapon staring at the heavens and black figures crowding around it.

I wondered what it was.

I decided to research the legend of the Heavenly Dragon after returning.

“Well, let’s take a break for a while, and then we’ll set up camp.”

After dropping off our bags at the entrance of the cave, we decided to go about our business.

Rita took a look around the cave.

Aine started preparing for the meal.

Cecile stood guard at the entrance of the cave. I left Reggie with her, as support.

And I…

“Well, then, please, … big brother.”

“Please do as you wish with me, Master …”

I was with Iris and Rafilia in the back room to ‘stabilize’ their skills.

I had used [Quick Restructure] on Iris and Rafilia.

Besides, it was my first time creating ‘4-concepts cheat skills’, so I didn’t know how long it would take to destabilize. I wanted to stabilize it as soon as possible.

“This feeling of being connected with Master is not so bad.”

Rafilia touched the [Mana Thread] that was connected to her chest.

The [Mana Thread] was a side effect of [Quick Restructure], and was only three meters long.

As long as it was present Iris, Rafilia and I couldn’t be separated. To put it bluntly, we had to bathe and change clothes together.

‘That’s all well and good, but … no, I’m still uncomfortable.’

Iris was holding her cheeks in embarrassment, and Rafilia looked… kind of happy, but that was it.

“Well, after you, Iris.”

“Can I go first?”

Pointing at herself, Iris shook her head.

“Brother created your skill first, didn’t he? If so…”

“I’m an Ancient Elf, albeit a Replica. The fact that a part of the Master trembles inside my body… is not a reward… nor is it what I want…”

“Ok then, Rafilia, I will stabilize you after Iris.”

Rafilia turned around and I could see her red nape as she sat on the ground, holding her ears with both hands.

“Iris will be embarrassed if I’m looking at her. That’s why I’m turning my back.”

“Master…”

“I can’t leave this place because of [Mana Thread]. Iris, since this is your first time, you might be nervous about a lot of things. So I’m going to pretend that I’m not here … and I’m not here … and Iris and Master are going to leave me here in this state …Hmmm, hmmm, hmmm…”

Rafilia refused to budge.

‘It can’t be helped. Let’s respect her wishes here.’

As a matter of fact, it was the first time I had restructured Iris’ skill, and I didn’t know how her Dragon Blood would react. Besides, she was still small and weak. I wanted to stabilize her as soon as possible.

“Well, Iris. Come here.”

I sat down, leaning against the wall of the room.

“… Yes. Big brother.”

Iris sat down with her back to me and her knees together between her legs, as if she was afraid.

Her tiny head was around my shoulders.

Iris was wearing a “traveler’s dress” that she had bought before the quest. It was a thick cloth and had more protection than her usual dresses.

“If I knew I was going to have my ‘first time’ with my… brother, I probably should have worn my usual dress.”

Iris pinched her dress and sighed.

“… I am not as mature as others. I am tiny … while also dressed like this, brother must be disappointed.”

“No matter how you dress, you will still be Iris. You are my slave.”

“But… this dress makes the poor me even poorer.”

“No, of course not.”

I stroked Iris’s disheartened hair.

“This appearance is proof that you have become one of us. Or do you want to go back to living in the back of a mansion, wearing clean and tidy dresses every day?”

“────!”

Iris shook her head vigorously.

She touched the Dragon scale choker on her neck, looking up at me.

“I belong to you, big brother.”

“Yeah.”

“No matter how small I am, no matter what I am wearing or what I look like.”

“That’s what I’m talking about.”

“It doesn’t matter what I wear, does it? I should give my all to my brother without holding back.”

Iris squeezed my hand and smiled.

“And if I could get brother to …, maybe I will grow up a little.”

“There’s no need to rush. Iris, stay put.”

It was just like Iris to go out of control.

“No. That won’t help me get closer to my brother, will it?”

“I don’t think there’s any distance anymore.”

Iris was in my arms, pressing her body against my chest, which was tickling me.

We were in close contact with each other. And to be honest, with zero distance between us.

“We’re not united.”

But Iris shook her head, unhappy.

“I see. Then let’s be one.”

I put my hand on Iris’s chest.

“Iris.”

“Yes, … big brother.”

Iris, red up to her ears, nodded.

“Come inside Iris, please. Soul Brother.”

With a thump, Iris’s heart raced.

I could feel her body heat through the fabric of her dress.

“Activate [Skill Restructure LV4].”

I activated my skill and saw Iris’s [Fantasy Space LV1] in the window.

[Fantasy Space LV1]

‘The skill to ‘visualize’ ‘images’ in your mind and ‘around’.

The characters and concepts were a little off.

It showed just how unstable the skill was a precursor to destabilization.

“… big brother is coming in from … my chest.”

Iris mumbled, her face red.

“He is in the center of my chest slowly, coming down towards my stomach… legs … ahh it feels so warm. His hands … reaching deeper, …He’s touching me.”

Iris began to mumble, her eyes blurry.

“My chest…stomach… is tingling. My navel area is itching. It’s gentle and soft and … like my brother is infiltrating in.”

“Iris?”

“Huh…?”

Iris opened her eyes, which were almost closed.

“What were you doing?”

“I was explaining where your mana came from.”

“Oh, no. I’m so embarrassed.”

“You can keep explaining, but I’m going to touch on your skill now. Are you ready?”

“Ah… of course.”

Embarrassed and holding her mouth with both hands, Iris nodded repeatedly.

“I, Iris Hoffimier, may be tiny, but I am the Sea Dragon’s Shrine Maiden. I will not make the same mistake again!”

“I’ll do it slowly. Just let me know if it gets hard.”

“…, yes.”

‘It is a ‘4-concept cheat skill’, it is a little different from others.

‘I want to put as little strain on Iris as possible.

Let’s start from the bottom.’

I touched ‘mind’ that was off…

“Aah!”

Iris’s legs shuddered.

“Ahh…ahh…ahh… What’s … this?”

Iris squeezed her beautiful toes, opened them, and…

“Brother is rubbing my… legs… between his fingers…rubbing …his…fingers…”

“Legs?”

I touched ‘mind’ again…

“No, no … same place … not … there. It’s bad… between the yips… hey…”

I saw Iris getting goosebumps on her legs, which were slightly cherry red. She rubbed her knees together sadly. Sometimes, her toes were tipped away, legs stretched out, hips lifted - then the hips relaxed-

Realizing that she was making a sound, she held her mouth… but couldn’t stop making sounds…

She rubbed her knees together again - and again.

I was touching the fourth “concept,” but Iris seemed to feel that she was being stroked all over her legs.

The response was different from the usual stabilization I used to do. I wanted to check it out.

“Detailed disclosure of Iris’s condition.”

When instructed, a full body view of Iris appeared in a separate window.

On that window… I saw that the mana flowing in both her legs was getting stronger.

The fourth concept I was tinkering with was ‘mind’.

‘If I lightly pinch “around” with my finger…?’

“Aaahhhh!”

Iris’s buttocks quivered.

“Oh, my dear, …, no. Weak point … is all over … And … in my head … tick tock … hyaaah!

Iris screamed.

I just lightly pressed my finger on the concept ‘around’.

Iris, holding the base of both her legs, shrank her body.

Her back was twitching and cramping because of a touch of mine.

I double-checked Iris’ full-body view.

The moment I touched the third concept, the mana from above Iris’ knees to her lower abdomen became stronger. Specifically, what used to be a skin color became a cherry color. Then, when I touched the second concept - she said ‘in my head’?

“… Hmm! Oh … Ha.”

When I lightly pinched the ‘image’, the area from the top of Iris’ navel to the bottom of her chest was stained cherry red.

“────! ────! Aah! …”

And her reaction changed.

Iris turned her chest and grabbed the hem of my jacket, squeezing it. She had hollow eyes, but her mouth was open. I touched her nape as I was worried but it resulted in her making a sweet “Hyan” sound.

‘I found out the secret of the 4-concept cheat skills.’

Each of the four concepts were linked to a part of Iris’s body.

From the bottom, ‘toes to knees,’ ‘above the knees to below the navel,’ ‘above the navel to the chest,’ and ‘chest to head’. It was as if the skill had become Iris’ alter ego.

And when I touched one of the four concepts, the corresponding place in Iris’ body reacted.

The mana was flowing into that area and stimulating Iris… or something like that.

“… So this is the power of [Skill Restructure LV4] … It’s pretty dangerous, huh?”

To put it bluntly, it’s was a skill that… allowed someone to completely dominate their slave.

If the 4-concept cheat skills were the slave’s alter egos, then by controlling them, the Master can control the slaves however he wants. But that’s assuming he has the [Skill Restructure LV4] skill.

In exchange for making the slave stronger, the Master gets tighter control over them.

The [Skill Restructure] was equipped with safeguards like that…

‘… I don’t intend to completely dominate my slaves, though.

‘Let’s just say that this effect is just to make your skills more efficient and stable.

‘If the ‘concept’ of the skill is linked to Iris’ body, I can tell her where the stimulus will go. That way, Iris will be able to prepare herself.’

I was about to stabilize the third concept ‘around’ and the fourth concept ‘mind’.

“Iris, listen to me for a second.”

“… wow … yes. Brother.”

Iris looked at me with downcast eyes.

She was rubbing her toes and knees.

“Brother was exposed to …my… What should I do? … It’s embarrassing. Touch me. I want … it … but…”

“It’s okay. I don’t think it’ll be too much of a burden anymore.”

“…Huh? Hmm. Oh, …”

I nuzzled her neck to reassure her, and Iris closed her eyes pleasantly.

“I figured out how to stabilize your skill efficiently. Iris, your skill’s third and fourth ‘concepts’ are unstable, so I just need to focus on those.”

“… so, is that …?”

“Yes. It corresponds to the area from your toes to your navel. So you just need to be prepared for stimulation in that area. I’ll take care of the rest.”

“Yes, … please., big brother? Please.”

Iris looked at me with a bright red face.

“From … toes to … my navel is … my toughest… Oh. Wait. If you do that now, … I will…”

“… What will happen Iris?”

“… I don’t know!”

Iris puffed up her cheeks.

“I… understand. Big brother will fix my skill which will stimulate my body from my navel to toes. …Please like it me…, no, it’s not that I don’t like it, brother …, it’s just that …”

“I see.”

Iris was clearly conscious and seemed to be okay.

I resumed stabilizing her skill, pressed on the ‘concept’ and poured mana into it.

“…Brotttthhheeeer!”

Iris’s legs start to shake.

“Ahhh! It’s a little … different from what I was expecting, but it’s … amazing … I… I am… ah.”

“Can you continue, Iris?”

“Mmmmmmm!”

Iris held her mouth and shook her head repeatedly.

‘Okay. Let’s go as efficiently as we can.

‘If I take too long, Iris might not have enough energy.’

While watching Iris’s condition monitored in the window, I decided to fix ‘mind’ which was at the bottom first…

“──── Hmm.”

I then focused on ‘mind’ with the tips of my fingers.

“Brother… that’s my … finger … one by one … squishy. Fuuu… oh. No.”

‘Okay, ‘mind’ has moved a little bit back to its original position.’

I then looked at the third concept, ‘around’ which corresponded to the area from Iris’ knees up to her navel.

“Hmmm, ────────!”

Bikkun!

Iris’s small body bounced.

“Brother! Don’t make me blank… out. Don’t ──── stop …, don’t ──── stop ──────… again.”

Iris arched her back and rubbed her little butt against my body.

“Just hold on a little longer, Iris.”

“I am going to melt… melt… into… big… brother… and…become… one…”

The “concepts” that had been out of place were fixed.

The word “Stable” slowly appeared in the window.

“Brother’s… mana is coming… from my toes… legs… my navel…aaaaahhhhhh ──────!

Sweat raised the “Dragon scales” on Iris’s shoulders.

It reacted to Iris’ and my mana, and began to glow pearly.

Iris was shaking her body in small increments. My mana was flowing deep into her body. It spreads to Iris’s whole body figure, which I was monitoring. The skill had stabilized.

“Stabilize!” Execute ‘[Skill Restructure LV4]”

Gakun

Iris’s small body trembled so much that I thought it might break.

Then, she slumped and relaxed.

[Fantasy Space LV1]

The skill to ‘visualize’ ‘images’ in and ‘around’ your ‘mind’.

‘Good. Skill stabilized.’

Just to make sure there were no loose ends, I ran my fingers over the whole thing…

“… haha. Ah …”

Iris’ body shuddered again.

The ‘4-concept cheat skills were very close to the slave itself.

It’s as if the concepts had become part of their body itself.

‘Once I’ve ‘restructured’ them, I’d better not take it out again at … Let’s just keep it stable.’

“Brother… I… feel… hot…”

“Yes. Then I’ll ask Cecile to bring you some water…”

“It’s hot at … It’s hot.”

“Y-yes, Iris?”

Plop, plop, plop!

Iris unbuttoned her dress as if she were trying to rip it off.

Then she put her hand on her skirt and pulled it all the way up to her head.

“If I wear this …, I’ll go … crazy. …it’s so hot …”

After shedding her clothes, Iris laid down against the wall.

When I checked Iris’ status in the window, it said “Releasing Mana Residue”.

It looked like she needed to release the mana I had put into her.

“I hope you don’t catch a cold.”

I put my jacket on Iris, who was lying beside me.

Iris shook off the underwear that was stuck to her legs, hugged my jacket, and began to breathe soundly.

Her status was: … “Releasing Mana Residue: Steady”

‘There doesn’t seem to be any problems.’

“Well, now, Rafilia.”

“Oh, I’m fine, I’m fine.”

It was an absolute lie.

There were beads of sweat on her neck, and her cherry pink hair was stuck to her forehead.

“Rafilia Grace is an excellent slave of Souma Nagi. It doesn’t matter if her skills remain unstable. Even if it stays like this for one more day…”

“Okay, okay. Let me ‘stabilize’ it quickly.”

Without question, I touched Rafilia’s chest to check the state of her skill.

Rafilia’s [Dragon Whirlwind LV1] was…

[Dragon Whirlwind LV1]

‘Control’ the magic to ‘tornado’ ‘freely’ ‘create’ and.

It was pretty much a free-for-all.

“… Come on, Rafilia.”

“It’s nothing, really. It’s nothing. There’s still more to come.”

“So why are you trying to escape?”

“But a little more … neglect play has its own flavor.”

“What are you talking about? You are a descendant of the legendary Ancient Elves. Come on, don’t run away!”

I summoned the [Mana Thread] from the window and tied up Rafilia’s [Dragon Whirlwind LV1].

“Oh, what? I can’t move my body.”

At the same time, Rafilia’s movement, which had been trying to escape, stopped.

She was still on all fours, stiff as a rock.

But it was also a good thing.

“It’s not funny. I have to stabilize your skill.”

The 4-concept cheat skills are deeply connected to their owners.

So it seemed that if I restrained the skill, the user couldn’t move either.

When I explained that, Rafilia’s slightly wet eyes narrowed.

“I see. Even slaves who have acquired powerful skills can never go against their Master.”

“You’re not listening.”

“But, well, you know…”

“It’s bad, isn’t it, Level 4?”

“It’s a reward for me, though.”

Rafilia turned red, even the tips of her pointed ears, when she said so.

I sat Rafilia, who couldn’t move, against the wall. Her hands were on her knees. I spread her knees apart so that I could get close to her.

Rafilia’s sweat-soaked body moved as I wanted it to, as if it were being controlled by an invisible thread. It was like she was being forced to do something on command.

‘I will only do this if they really resist.’

I mean, the only person who would resist ‘stabilizing’ would be Rafilia.

“Hey, Master.”

Rafilia looked at me with a lonely look in her eyes.

“I was made, wasn’t I?”

“I know. I just told you earlier I don’t care.”

“I know. But there may be others like me, you know?”

“I will think about it when we find someone.”

We didn’t know if they were supposed to start moving in the same time period, and we didn’t know how many Replica existed in the first place.

Of course, I was going to protect them if I found one.

“If any of Rafilia’s sisters are working black, I’ll help them as much as I can. Don’t worry about it.”

“Master will? But even if you find other replica’s I will be the happiest of them all, you know.

Rafilia then put her pure white palm on my hand.

“I’m the only one of my type who knows the joy of being touched by a Master. That’s why this Rafilia Grace is the strongest.”

“You’re the strongest?”

“I am already the strongest. It’s super invincible!”

“Mmm,” Rafilia clenched her fist.

“Besides, Rafilia isn’t ‘made in the past’ anymore.”

“What? Master?”

“I’m rewriting Rafilia. I don’t know what the Ancient Elves were thinking, but that doesn’t matter to the present Rafilia anymore.”

When I said that, Rafilia’s eyes widened, as if she was startled.

“Rafilia is my slave, customized by me.”

I didn’t know what the “Ancient Elves” who created Rafilia were thinking.

But I destroyed the bad luck skill they had created. The Rafilia that was in front of me at that moment was something else. She was thinking for herself, and working for herself. She was a new Rafilia, freed from her black mission.

“So you don’t have to worry about being ‘made’ anymore. I’ll tell you that much.”

“Master…”

Tears spilled from Rafilia’s eyes.

“But, but I… I’m grateful to the person who made me into what I am today.”

Rafilia grabbed my hand and pressed it against her soft … large chest.

It’s as if she was trying to wrap those around my hand.

“I can hold Master’s hand like this because he made my breasts so big. I am very grateful for that.”

“… I see.”

Rafilia looked refreshed at that moment. She seemed to have cleared her head.

‘I’m glad. This alone is worth conquering the Valley of Mist…’

“By the way, Master, which do you like better, big breasts or tiny breasts?”

“A good moment just got ruined in an instant!”

“It’s important, you know? All of us fellow slaves want to know.”

“… eh.”

“Come on, come on, come on, tell me.”

Rafilia kept her face close to my ear and breathed into it.

“… Any is fine. It only matters who it belongs to”

“Oh, Master’s embarrassed!”

Rafilia smiled.

She sniffed like she was proud of her victory even though her skill was shaking inside her body. She looked into my face, and smiled wryly. Then she looked at Iris.

“Iris, please listen to me! Well, Iris, you’re still fluffy. Hey, look here. Master is embarrassed. It’s very precious… ahhh? Aah!

“Okay, let’s start the ‘stabilization’ process.”

‘If we don’t, we’re not going to get anywhere. Quickly and promptly.’

“Master? You can’t suddenly pour a lot of mana into me! It’s not fair! You can’t make it stronger. You can’t shake the letters at the bottom of my skill all at once. You can’t… you can’t do that.”

I didn’t hear any of her complaints.

I couldn’t leave the 4-concept cheat skill unstable any longer.

‘Now that I know how to stabilize…’

I stabilized Rafilia’s 4-concept cheat skill with the fastest and greatest efficiency.

“Funya …”

Deflated, Rafilia laid down next to Iris.

I checked her status in the window, but there was no problem. It seemed that Rafilia was more efficient at releasing mana residue than Iris because her body was larger. She was still a bit twitchy, though.

“Good night. Both of you.”

“…Brother…I…love…this…”

“…Master… Heh. Heh heh heh.”

Both of them were doing well after “stabilization”.

‘Then let’s switch guards. Reggie (who wanted to observe the “stabilization”, so I gave Cecile the sword) is probably getting nervous.’

When I tried to leave the room, I felt something touch my foot.

Something hard and round.

It was the Heavenly Dragon Egg.

“… you, I left you with Cecile, didn’t I? Why are you here?”

The egg didn’t answer me.

“Maybe you came to check on me?”

There was still no reply.

“I’m going to keep watch and make my rounds, what do you say?”

When I started walking… The egg followed me.

“All right. But I’m only staying with you until we get you to the villa.”

With that, I picked up the “Heavenly Dragon Egg”.

Looking to the side, I saw a mural of a Heavenly Dragon on the wall of the passage. A pure white Dragon with its wings spread.

I couldn’t imagine the egg I was holding turning into that huge winged Dragon, though.

“In return, when you grow up, will you be my ally?”

When I said that, the Heavenly Dragon Egg became a little warmer.

‘I guess I’ll take that as a yes.’

***

“Master! How dare you leave me alone?

“Good work. Nagi.”

At the entrance of the cave, Cecile and Reggie, who had taken loli form, stood guard.

They were playing rock-paper-scissors to kill boredom and to stay awake as they were tired. Instead of chips, they were exchanging broken twigs. So far, Cecile seemed to be winning.

“Rita came back once a while ago.”

Leaning forward toward me, Cecile said.

“She said that there are no monsters around at all. But she still went to look around a little farther, just in case.”

“Also, the Elf girl with the big breasts said she found the cave with a bath. You might want to go there later. Or rather, take me there, Master.”

Reggie said that, as if she were screaming.
