I Possessed It Instead of My Younger Sibling

121 – Side Effects

A large cavity with countless overlapping spatial expansion spells.

Chajajajajang-!!!

There, knives and knives become entangled, and a sharp noise rings out.

There are only two people making that sound.

“That’s great. My skills have improved a lot.”

“It’s all thanks to the Master.”

One is a man wearing a cloak like night.

The other is a dark blue-haired female swordsman with a cool-headed expression.

The two men, clad in blue wings, were continuing a high-speed battle, moving across the common sky.

Soaring ascents, sudden descents, right-angled turns… At speeds exceeding 300k/m per hour, the two perform a technique that would make even veteran pilots blush, and every time they intersect, they are fighting and fighting in an instant.

The sight of countless sparks shooting out in all directions each time the sword was struck, leaving a blue afterglow in the air and slowly falling down from the air, was so beautiful that even if you knew it was dangerous, you would want to get closer and look at it.

“Then let’s finish it slowly. I’ll speed up, Ezerina.”

“Yes… !”

As the man increases his flight speed, the woman accelerates as if following him.

310k/m… 320k/m… 330k/m… The speed is gradually increasing

Chaejaejaejaejaeng──!!!

As a result, the battle between the two prosecutors becomes more and more intense.

Even though the flight speed had already exceeded 400k/m per hour, it did not stop and continued to increase.

“Tsk… !”

The sword attack and defense that became more intense in proportion to it, the fatigue from the burden of high-speed flight, and the consumption of magical energy that disappeared like melting snow overlapped. The mental and physical load on Ezerina was rising rapidly.

Her face was already drenched in sweat.

Nevertheless, the man continued to increase her speed.

The moment it exceeds 450k/m.

“Oh my… !”

Ezerina’s concentration of her magic power her was nearing its limit, and the balance between her flight and attack and defense was disrupted.

“It’s a gap.”

“Ugh!?”

Puck-!

And the man who did not miss that moment delivered a heavy blow directly to Ezerina, who had a look of despair on her face.

In an instant, Ezerina’s consciousness was blown away and she was forcibly released. With that, today’s training ended.

Tub-

After I caught Ezerina from falling. She slowly descended to the ground, holding her with both hands as she was used to.

“Ah… Uh, ah… ?”

Then, her eyes met the dazed eyes of Ezerina, who seemed to have just come to her senses.

“Thank you for your hard work today.”

“Ah, no… Master… Thank you for your hard work… “

When she looked down at Ezerina in her arms, Ezerina blushed and answered in a low voice, as if she was still embarrassed, even though it had been repeated for nearly two weeks.

Ezerina, whose default expression is always calm and cool-headed, looked so shy, perhaps because it was a gap from her usual self, but it was very cute.

As I watched in silence, Ezerina opened her mouth in a hushed voice.

“Um, Master… You don’t have to sit so tight… ! You must be smelling a lot of sweat right now… “

“Hmm? You don’t have to worry that much. It’s not that bad, and I think it actually smells good.”

“~~~~!!!”

“Besides, I also sweat, so I might actually smell. I’m sorry if you felt uncomfortable.”

“Oh, no… ! It’s okay!… It’s actually nice that it’s full of the Master’s body odor… Eup!”

When I apologized, Ezerina, who had been muttering so softly that even I couldn’t hear, suddenly covered her mouth.

“Hmm? “What did you say?”

“Oh, it’s nothing. You can get off now… !”

When I questioned Ezerina for not hearing what she said, she shook her head quickly. As soon as she got to the ground, she started pattering and so quickly that I couldn’t imagine that she was in a state of magical exhaustion. After getting out of his arms her her her her.

“Seuuu0 Trivance Contrivance with Law with the word of the word Her Honor Her Her Her, “

Suddenly she took a deep breath and began to take her deep breaths.

I don’t know why, but it seemed like he was trying to calm down, so I waited for a while. When she regained her composition, she approached and spoke to her.

“Ezerina, anyway, this battle was really great. I can finish my intensive training now.”

“Ah… Thank you, Master. I’m happy even if it’s just empty words.”

“It’s not an empty word. My swordsmanship is now within the realm of a master, and the waste of magical power that was lost in vain when I went crazy and couldn’t be controlled when using [Fight] Has almost completely disappeared. And The sense and skill of fighting while flying at high speeds seems like I have completely mastered it.”

Approximately two weeks after taking Ezerina under her command. In the meantime, she spent most of her time working as the mercenary Mist Tail training Ezerina.

This is because there is no news of additionally discovered Demon God Church, but the faster Ezerina’s skills are raised, the more power she will have to help in the war against the Demon God Church.

Therefore, even if I wanted to improve my skills as quickly as possible, it was inevitable that the training schedule would be so difficult that the word Spartan would be meaningless…

Ezerina silently followed my training without showing any signs of hardship.

Thanks to this, Ezerina’s outstanding potential and talent allowed her to hold the title of the 8th Bishop in the future, and her skills grew so quickly that the words “Ilchwiwoljang” Were meaningless.

Therefore, I praised her for following the training to the end and with satisfaction for her improved skills, but after hearing my praise her, Ezerina opened her mouth in a slightly gloomy mood.

“… However, I failed to follow the master until the end. “My skills are still lacking.”

“No, your skills are already sufficient. The reason you couldn’t keep up until the end is simply because you don’t have enough magic power. If it weren’t for that, you would have been able to keep up until the end. And it just so happened that something that could solve that problem was completed not long ago. “

I took out a book from subspace and handed it to Ezerina.

“Accept it. This is the mind method you will use from now on.”

After leaving the library. It was made just before I came here and was completed less than 3 hours ago, so it was literally a recently made piece.

“…This… Could it be that the Master made it himself?!”

“Yes. … Ah, even if I made it myself, you don’t have to worry. It’s at least an S-rank technique.”

“…Huh? S-rank…!? You can’t make something like that so easily…! …Oh, no, but if you’re the master… Huh…? But the master met me before half moon…?”

Ezerina was confused, looking back and forth between the book in her hand and me.

I motioned to Ezerina to read the book in silence.

Ezerina reflexively opened the book at my gesture,

“This is…”

In an instant, his complexion changed and he began to concentrate deeply on the contents of the book.

She must have realized it instinctively.

The mind method written in the book is perfectly suitable for you.

The name of the mind law written in that book is [Cheonik Simbeop (天翼心法)]

Focusing on the field of wind, which is part of the Valhalla advanced mind method created in the library, we synthesized the main structures extracted from more than a dozen high-grade wind attribute mind methods and analyzed them through observation to further optimize the form, nature, and constitution of Ezerina’s magical power. It is a mental method created only for Ezerina, after careful tuning.

[Heavenly Ik Simbeop(天翼心法)]

Difficulty of acquisition: A+

Operation Difficulty: A+

Magic attribute increase rate: S

Attribute value increase rate: S

Physical stat increase rate: S

Main magic attribute: Wind attribute

Main rising stats: (Dexterity, Senses)

Special note: When used by ‘Ezerina Wiz’, the difficulty of acquisition and operation decreases by 3 levels.

-When used by ‘Ezerina Wiz’, magic power, attributes, and stat increase rate increase by 1 level.

-〈magic attribute information engraving〉: Acquisition speed increases 4 times.

Perhaps thanks to optimization, when Ezerina uses it, the difficulty of learning and using it drops from A + to B +, and otherwise rises to S +.

There, imitating the technique of the first great wizard I had experienced just a few hours before, I mixed the ink used to write the book with ‘〈 Magical power containing the essence of Heaven’s Heart 〉’ and wrote it down.

Just by reading the book, the structure of the mind will penetrate into your mind and your understanding of the mind will quickly increase.

‘It’s embarrassing to compare to the Great Wizard, who contains decades’ worth of information in a single dot, but it’s still worth using.’

If I keep honing this skill, I think I can use it in many ways.

At that time, Ezerina, who had finished reading her book, raised her head and opened her mouth with a slightly flushed face.

“Master, this is truly an amazing mind technique! It is very deep, yet has effects that easily exceed expectations, and is surprisingly easy compared to it. At this level, you can master it in two months… No, one month.”

“It’s been a month…”

I stroked my chin and spoke.

On average, it takes approximately 2 years to fully learn the B-level mind technique.

If you think about it, one month can be said to be an exceptionally short time, but…

To be honest, I didn’t wish I had learned it a little faster.

‘Should I use ‘that method’? If so, you could use it right away…’

After thinking for a moment, I decided to ask her partner, Ezerina.

“Ezerina, if there was a way to use the Mind Technique right now, would you do it? This might be dangerous for you…”

“I will.”

“… That’s an immediate answer.”

Ezerina nodded her head immediately without any hesitation at my words.

“If I can use mental techniques quickly, it will be of even more help to the master. If so, there is no reason not to do it.”

“Okay. Then just sit back and relax.”

After making her sit down on her ground, I took out her elixir from her subspace and handed it to her.

She sat behind her, placed both her hands on her back, and opened her mouth.

“Ezerina, from now on, I will ‘put’ my magic power into you and melt the magic power of the elixir into your body, and at the same time, I will use that magic power to directly use the Heart Law until 〈 Heavenly Wing Heart Law 〉 is absorbed into your body.”

“That… It was clearly an act that my teacher had done in the past that was tantamount to suicide…”

“Yes. It is an external method that was used by noble families in the past but was abandoned because it was too dangerous, and is now almost a taboo.”

The magic power inside the body, that is, the magic power that has an owner, has the property of violently repelling the magic power of others. A representative example of a technique that utilizes this property would be a penetrator that forcibly penetrates both the impact of a blow and one’s own magic, turning the inside into a mess.

And what I’m trying to do now is a technique that is at least dozens of times more difficult than that penetrator.

It is a technique that is close to the pinnacle of magic manipulation, in which you insert your magic power into the opponent’s mana rod, suppress the backlash with that magic power, and use your mind instead.

The Mana Rod is an extremely delicate organ similar to a type of nerve. Therefore, if any rejection occurs at the moment of inserting and operating magical power, the Mana Rod will be injured, and the owner of the Mana Rod will be in excruciating pain as if his nerves were being ripped out.

In severe cases, the mana rod may be damaged, resulting in permanent inability to use magical power, or death from shock.

Even if a direct blood relative with almost similar innate magical properties becomes the caster, it is an extremely dangerous technique with a failure rate of over 70%.

Adding that you can stop now, I conveyed this information to Ezerina without omission.

Ezerina──

──Gulp

──I swallowed the elixir in my hand without saying a word.

That was her unspoken answer filled with firm intention above all else.

It would actually be rude to her to dissuade her any further.

I closed my eyes and increased my concentration.

To repay her trust her, you must never fail.

… And well, even though I was very scared, I wasn’t confident in myself.

You are the one who will fail.

Ugh-!

Just before the pulled up magic passes through the palm and flows into Ezerina.

I twisted my magic power and converted it to be completely ‘identical’ to Ezerina’s original magic power.

The nature of magical power, purity, ratio of attribute values, concentration… In fact, even if there were a device that could observe magic power at the molecule level, it would change it to the same extent that it could easily be deceived.

Through the miracle of combining my extreme magic power manipulation ability with 〈 observation eye 〉, my magic power succeeded in settling gently into Ezerina’s heart without the slightest resistance.

‘This is halfway there.’

Now, all that remains is to manipulate magical power to use the Cheoniksimbeop and absorb the magical power of the swallowed elixir into the body without any loss.

I slowly moved my magical power──

“Hiya… ?!”

… Hiyat?

I stopped my magic when I suddenly heard a completely unexpected feminine sound, opened one eye and slowly looked ahead.

“… ?!… ?”

There was Ezerina, her face blushing for some reason, covering her mouth with both hands in embarrassment, breaking her usual cool expression as if she, too, was started by the sound coming from her her own mouth her her her.

“Did you have any pain, Ezerina?”

“Oh, no… There was no pain… But, uh…”

I asked her if she felt any pain from the movement of my magic power, but Ezerina denied it, but somehow she did not speak as clearly as usual and muttered her mouth.

“Ezerina?”

“Well, that is…” ” . So that is…”

“Ezerina, tell me clearly what you felt. If something unexpected happened, you should stop right away. Was there pain? Or numbness or burning? If not…”

“Oh, no, there was no pain at all! … It’s just that… “

“Just?”

“That, s*x, s*xual pleasure…”

… Pleasure?

“…Yes, when the master’s magic moved, that part felt like a tingle…”

Ezerina explains in detail what she felt with a look of shame and embarrassment on her face.

After listening to everything she said, the conclusion I came to was…

“It’s an unexpected phenomenon, but there’s no major problem.”

“Is that so?”

“Yes. I changed my magic power to be the same as your magic power, so there is no rejection, but it is someone else’s magic power that you cannot exercise control over. When that magic power moves, it creates a feeling of pleasure in the nerves called mana rods and in the body that is closely connected to it. It must be causing unexpected stimulation to the nerves.”

An incident that occurred due to too perfect magical manipulation.

If the manipulation of magical power had been even the slightest bit clumsy, you would not have felt pleasure, but rather extreme pain as if your nerves were being squeezed out.

“Then I will assume there is no problem and proceed.”

“Well… The way to solve this is…”

“I have no choice but to endure it.”

“Yes…”

Having once given up on Ezerina, I activated her magic again.

“~~~!?!?─!!!”

Using the Mana Road as a path, like a flowing river, I flinched every time my magical power stimulated the blood in accordance with the principles of Cheonik’s Mind. I could feel Ezerina’s movements of her her body her her her trembling through her her palm her her her her.

I concentrated deeply on magic manipulation to distract myself from that.

Shoot aaa-

As I concentrated, the stream of magical power seemed to gain momentum, almost twice as fast as before.

With its momentum, it swept away all the elixir’s mana that was slowly leaking out of the body, and slowly expanded the mana rod, allowing the elixir’s mana to seep into the cells at the ends of the body, like spraying water on cracked dry land .

And that work was done for about 5 minutes.

Magic attribute: 35(D) 〉 40(D+)

Function : … New〈Cheoniksimbeop LV1〉

Ezerina’s increased magic stat and the addition of 〈 Cheoniksimbeop〉 in the function column announced that this work was completed successfully.

Looking at it with satisfaction,

“Haaah… ! It’s all over, huh…Is it… ?”

Ezerina, her face flushed, her breathing heavy, her eyes half-open, asked with difficulty, her voice trembling but conveying her relief.

I looked at her like that and without her her words her her her ──

Whoosh!

──A pile of elixir was poured out from subspace.

“Um, master… Is this… ?”

Ezerina asked, looking at me with her pale complexion…

“I’m sorry, but it would be better to increase her magic power to its limit. Hang in there, Eze Rina.”

I cruelly trampled on her wishes.

Forgive me, Ezerina.

But it’s so efficient that I can’t help it.

******

Magic attribute: 59(C+)

Function : … 〈Cheoniksimbeop LV6〉

About two hours later.

After absorbing a total of 27 elixirs, Ezerina’s magic power rose to the maximum it could raise in her current state.

“~~!!!~~!!?!?”

However, in return, Ezerina was left in a state that was beyond words.

I can’t explain it specifically, but she was in such a bad state that when she came into the community smiling brightly, you saw her older sister’s face and her face instantly turned bright red and she walked backwards and left the community. Let me just say.

‘Yes, this is prohibited from now on. I probably won’t have to use it at all. It’s too dangerous in many ways.’

I made that promise while looking at Ezerina, who was still lying on the floor and trembling.

‘Anyway, I’ve done almost everything I can now through training. I guess I’ll have to practice it a bit to get used to the new physical specifications… Are there any useful dungeons left around here? … Huh?’

Tiring-

At that time, the terminal in my pocket rang.

According to information, the sender is a black cat.

And the contents…

“… Wow, it’s perfect timing.”

I spoke to Ezerina, who was slowly coming to her senses.

“Ezerina, a new branch of the Demon God Church has been discovered.”

Flash-

At my words, Eze Lina’s eyes flashed and she immediately corrected her posture.

“Imprint them clearly. “The sharpness of the secrets was born from your cruelty.”

“──Yes, Master.”

In the depths of his indigo eyes her, a flame of murderous intent as cold as ice burned fiercely.
