The Main Characters That Only I Know-Chapter 275:

It was much easier than he had expected to unleash his initial technique.

Yu-hyun was bewildered by how smoothly it went.

It was even more comfortable to move his body directly than to hear the explanation from Gu Kyul. It was a hard thing to understand logically.

[Master.]

Someone spoke in Yu-hyun’s head.

A blunt and curt voice that spoke in short sentences.

It was Darwin’s demon.

‘Darwin, huh… Ah, I see. I get it.’

Yu-hyun quickly grasped the situation.

He got up from his seat and prepared to go out.

He had an idea of why this happened, but he needed to be sure of his hypothesis.

He was thinking of doing an experiment in a place where people’s eyes wouldn’t reach, when he suddenly came up with another possibility.

‘Wait. Do I really need to go outside?’

If what he thought was true, it would not only benefit him, but also the collectors who had become too strong and had trouble with their training.

Yu-hyun immediately put on a mask on his face.

The mask of aporia, which now had a complete name.

Four red eyes floated above the mask. Yu-hyun activated the power of the third eye, Descartes.

‘The power that transcends the boundaries of all reality and fantasy.’

The scenery around him melted away in an instant and a new world unfolded.

The place where Yu-hyun was standing was a vast plain that seemed to expand the training ground by hundreds of times.

He confirmed that and lightly jumped or stomped his feet.

He felt the touch clearly, even though he knew it was a fantasy.

‘This is the power of Descartes’ demon.’

The [Wonderland] created by Descartes’ power.

It could be seen as the most terrifying power.

Laplace, Maxwell, and Darwin were limited to strengthening their own powers, but Descartes was the opposite.

This power that showed illusions to others was too delicate and immense.

Yu-hyun had entered here knowing that it was a fantasy, but what if someone who didn’t know anything experienced this place?

‘What if all the years they lived were actually false? What if they were illusions planted by someone?’ 𝗳re𝗲𝚠e𝐛n𝗼v𝗲l.c𝐨𝐦

There is a term called brain in a vat.

A hypothesis that says that one’s real self is a brain in a vat, and that all the memories and experiences they have lived so far are false ones created by some crazy scientist through electric stimulation.

Of course, this hypothesis is practically meaningless because if one is really a brain in a vat, they wouldn’t be able to come up with the hypothesis of ‘what if I’m a brain in a vat?’ but what about Descartes’ power?

‘No, that’s not what’s important right now.’

Yu-hyun wanted to experiment with his power here.

He had succeeded in using mental realm, the variation technique of Seven Demons Black Sky Divine Skill, albeit very briefly and roughly.

He had to check if it was a coincidence or not.

‘Anyway, this place is a world made of fantasy. Even if I use all my power, it won’t affect the surroundings.’

Even the special space made for collectors couldn’t withstand Yu-hyun’s power properly.

It was a waste of time and effort to look for a place where he could measure his power.

In that sense, this Wonderland was the best space where he could use his power freely.

Yu-hyun concentrated his mind. His inner energy, which was as black as ink, swayed like ripples around his body.

He felt his strength drain out of his body, and his heartbeat and filled the empty space right away.

His energy, which seemed like a dot compared to the vast space, soon became a huge wave that swept over the surrounding area.

His body settled down calmly, but Yu-hyun’s head spun fast.

His eyes were seeing something else right now.

The power that Seo Sumin showed in the fight against Chulapantaka.

The flow of that huge vortex and how it eventually converged into one point.

And how he used his luck when that happened.

Kwarurururung!

A dark energy began to swirl violently around Yu-hyun.

One, two, three… There were exactly nine whirlpools.

The nine black vortices gathered in Yu-hyun’s right hand.

-Listen well. This power of mine is not meant to be used with weapons.

Seo Sumin said that and stretched out her right fist.

-This power is originally a technique that is performed with only a strong body. Weapons are just for increasing accuracy. Of course, it’s not bad to have weapons. It’s good if you have them, and it doesn’t matter if you don’t.

So the essence of it was ultimately a physical power technique that was performed with bare hands.

-If you really want to master this power, you will be able to use it properly with bare hands someday.

As if to prove that, Yu-hyun thrust out his right hand with the nine vortices.

-That is, Seven Demons Black Sky Divine Skill.

Kwarurururung!

A thunderous noise and lightning flashed as the air around him shook violently.

The overflowing power sprayed a strong pressure like a meteor around him.

The ground where Yu-hyun was standing cracked and shook roughly.

The nine swirling vortices soon twisted and merged into one.

I compress and condense them, weaving and mixing them together.

Nine whirlpools of power, each retaining its own strength, but amplified into a single thrust.

I unleash it.

A strike that pierces the existence of a star.

‘With all my might.’

What I envision in front of me is the Chulapantaka I saw back then.

The man who recited verses on a lotus, radiating brilliant light. I imagine him as an illusion.

The illusionary Chulapantaka recited his final verse.

And then, Yu-hyun’s mental realm collided with that light.

─────!!!

A fierce flash that shook the world and a thin black line that cut through that flash.

When everything disappeared, what remained was the still intact figure of Chulapantaka and.

The power of mental realm that scattered without piercing the light.

As I watched it, the illusion of Chulapantaka crumbled and vanished.

The broken world returned to its original form. This Wonderland even had the function of automatically restoring itself.

“Tsk.”

Yu-hyun clicked his tongue in disappointment.

He had tried his best to follow it, but he still couldn’t match the real thing.

He felt frustrated that he didn’t get the expected result, but if Seo Sumin had seen this spectacle, she would have been stunned.

Yu-hyun had almost perfectly performed mental realm, which Seo Sumin had displayed, without proper instruction and only hearing the name.

The biggest foundation for that was the ‘experience of seeing with his eyes’, but that was something that no one could imitate.

He saw it with his eyes and performed the same skill.

What made it possible for Yu-hyun was his incredible cognitive ability to not forget anything he saw once and.

‘A body that moves as it expresses what it thinks.’

Yu-hyun looked down at his body for a moment.

Underneath the suit that fit his body perfectly was the ultimate physique that Seo Sumin had mentioned in the past.

‘So this is why she called it the ultimate physique.’

The ultimate physique was not a name given simply because it was powerful.

It was more than sturdy and free of any waste in the body, and it could accept and manipulate any energy.

Not only that, but anything he saw once or came to his mind.

If he tried to implement it, his body would naturally move along with it.

People often say that they see and know, but their bodies don’t follow.

Knowing something and doing it are different things, and to learn something with your body, you have to repeat it hundreds of times through repetition learning.

But Yu-hyun was different.

If he saw something with his eyes or knew something in his head,

He could do anything with this body.

That was the ultimate physique.

The power possessed by Darwin’s Devil.

‘Beyond the insane vitality and unbelievable physical strength, being able to do anything with your body as you please. That’s a talent that would make any martial artist’s eyes roll back.’

It was not a level of physicality given by heaven. Even a genius who appeared once in a thousand years could not match Yu-hyun now.

Yes. If he had to put it into words, this was

Literally a devil’s talent.

“Laplace. Maxwell. Descartes. Darwin. All of you come out.”

As soon as Yu-hyun’s command fell, black letters clustered like bugs and revealed four devils.

The eldest Laplace stepped forward and bowed his head.

[Our master. Give us any command.]

“It’s not a command per se.”

Yu-hyun smiled slyly at the four devils.

“First of all, I need to test your power.”

***

After finishing all his training and returning to reality, Yu-hyun almost collapsed on the spot from the exhaustion that ran through his body.

‘Damn. Did I train too hard?’

What was more surprising was that even though he trained in the Wonderland, the effect of the inside affected reality when he came out.

‘It’s because of Descartes’ power. It’s not a simple illusion.’

What he did and experienced in the illusion was also ‘real’. If he used up his energy there, it was the same as using up his energy in reality.

The same goes for getting hurt in the Wonderland. The physical body in reality did not get exactly the same wound, but the pain and impact of the wound were real.

‘It’s dangerous either way, but it’s also much more efficient than doing it in reality.’

Above all, he spent more than six hours in the Wonderland, but when he came back to reality, less than an hour had passed.

The flow of time was much faster in the Wonderland, which caused this to happen.

The ratio of flow may not be that big now, but if he can handle this power more properly.

‘It might be possible to spend an eternity in the illusion while it’s only a moment in reality.’

Of course, he would have to raise his level more than now to do that, but it was enough to make him smirk at the fact that it was not impossible.

This settled how he would train the collectors of White Flower Management.

All that was left was to clear the way for his colleagues to go forward without stumbling on any rocks.

‘I’ve almost cleared up the Twilight Curtain and Hanul. The religious groups are getting noisy again lately, but they’re not annoying enough. The only thing left is Unleashed?’

The one he had to be most wary of was Jin Cheong-woon.

He was the one who possessed the same golden fragment as himself.

Even with Laplace’s power, he couldn’t glimpse his future, and he also had a power similar to Laplace’s, called ‘prophecy’.

‘He’s not going to do anything right now, but he’s dangerous beyond words when I think about the future.’

The five-fold mental realm that happened in Japan was just the beginning.

Ever since that man appeared in Korea, Yu-hyun had anticipated that something much more serious than the five-fold mental realm would explode in Korea someday.

He had to be fully prepared for that time.

***

The next morning of Yoo Il.

As soon as the day broke, Yu-hyun ordered the four collectors to gather with all their preparations.

They thought they might go to another mental realm and prepared accordingly.

They all held weapons and checked their outfits.

After confirming that they were all gathered, Yu-hyun introduced something they couldn’t understand.

“The reason I gathered you all here is because I found a good place. You will be training in the Wandering Realm from now on.”

“The Wandering Realm?”

“What is that?”

“Is that the name of a Mental realm? Bro?”

Everyone expressed their curiosity, but Yu-hyun only smiled and did not answer.

He just put on a mask. A devil-shaped mask with four red eyes.

“Don’t resist and just look into my eyes.”

The group did as they were told. They did not think Yu-hyun would do anything bad to them.

As they relaxed their bodies and stared into the eyes of the masked Yu-hyun, their heads spun for a moment.

When they came to their senses, they realized that they were standing somewhere other than reality.

“Wha, what? Where is this?”

“What is this? Where are we?”

A world so vast that the end was not visible. But it was also so barren and monotonous that nothing existed.

Everyone was bewildered by the appearance of this world.

“Calm down. This is the Wandering Realm that I created.”

Yu-hyun said that and explained that this place was a fantasy world created by illusion.

And in this place, time flowed slower, they could train without worrying about the aftermath, and the training here would also affect them in reality.

The group was skeptical at first, but they seemed to believe everything as Yu-hyun explained it one by one.

Even if they didn’t, they would find out after experiencing it today.

“But, if this place is a fantasy world, can we create anything we think of?”

“Of course. Well, technically I create it with my power.”

“Can you make something like a cake as big as a mountain?”

Kang Hye-rim asked with curiosity. She had been enthusiastic about reading books lately, which was Yu-hyun’s homework for her, so she was paying attention to her sugar intake.

She must have made a lot of money. Kang Hye-rim bought and ate all the sweet desserts she had wanted to eat until now.

Yu-hyun did not answer and snapped his fingers.

To everyone’s surprise, a giant cream cake over 20m high appeared right next to Kang Hye-rim.

Kang Hye-rim tasted it with her fingertip and was amazed by the flavor.

“Oh my god. It really tastes real.”

“As you can see, you can feel all your senses here. You can also use the power you have in reality. And this world is very sturdy, so even if the ground breaks, it will be restored and it won’t be destroyed easily.”

So there was no better place to train than this.

Everyone’s eyes finally lit up with intensity. Except for one person.

Yoo Young-min.

“Uh, if you say training, I…”

Yoo Young-min’s way of getting stronger was different from others. He earned points and made skills with them, and he got stronger with those skills.

It was a method that suited Yoo Young-min, who was full of tricks.

So he was not very familiar with the process of training.

The best way to get stronger was to go to Mental realms and hunt Phantasms or get clear rewards.

“That’s okay.”

He heard that voice next to him and felt his whole body shiver.

Seo Sumin.

The beautiful girl with white hair smiled at him.

“I’ll teach you everything.”

Seo Sumin was especially excited to come to the Wandering Realm.

She had felt like she had to restrain her own power lately, but thanks to Yu-hyun, she got a chance to let loose.

And for Yoo Young-min, Seo Sumin’s joy could only mean a huge despair.

“Sister Heavenly Demon?”

“Well then, good luck everyone. I’ll be back later.”

“Huh? Bro? You’re leaving?”

“I have something to do for a while.”

“Wa-wait! Sis! Sis!”

Yoo Young-min called out desperately, but Yu-hyun left the Wandering Realm without looking back.

Yoo Young-min became speechless.

“Ee-eeek!”

“Come on. Let’s start our hearty training.”

“Save meee!”

Yoo Young-min, who had dressed up in a nice coat for once thinking he would go to a Mental realm together, was dragged away by Seo Sumin without any resistance.
