Outsider

The ability to traverse space was achieved when, in the Dark Continent, through the influence of the Wishing System on Oboro's soul.

Therefore, he can always traverse space.

However, Oboro never used it.

Because of the unique nature of his soul, frequent use of it carries a certain degree of danger.

If you accidentally wander into the flow of time and space, you probably won't be able to come back.

However, since he has the will of the Demon Slayer world, and he is only making spatial jumps within a single world, he can receive a certain degree of 'protection'.

However, unless under special circumstances, Oboro should try not to urge him to activate.

He's been busy in this world for so long, and there are still many resources he hasn't collected... It's always good to be careful.

Having become familiar with Muzan's soul, I marked it.

Muzan had nowhere to hide.

"Don't be afraid, it's not your time to die yet."

Long stepped across the threshold and entered the room.

He said softly.

But judging from Muzan's expression, he didn't believe Oboro's words at all.

The Muzan was forced to use his power, even though he knew he was no match for Oboro.

The ground beneath their feet, the structure inside the house—all matter—transformed into flesh and blood in an instant.

Several walls of flesh were opened up with huge cracks, from which emerged small, deformed monsters.

These monsters have the same form as humans, except that their limbs and organs are misaligned, like failed products hastily molded by someone.

"This is incredible..."

Long's eyes lit up, and she exclaimed in admiration.

Faced with the threat of death, Muzan once again made a 'breakthrough'.

This method, similar to creating new life, is how Muzan, like a splitting cell, divided his own soul to create countless 'clones' that he controlled.

These 'dwarfs' also wield various bone-derived weapons.

Humans are born from blood, and bones are born from flesh... The soul drives changes in cells. Given that Muzan's time in soul training is relatively short, he can currently only transform cells into the 'bones and flesh' he is most familiar with. So what about the future? In the current situation, Blood Demon Art relies on the physical body, but in the future, it may rely on the soul, breaking free from the constraints of the physical body and becoming less singular.

Based on the soul, what new power systems can be derived? There are many, such as psychic Nen power, various superpowers, etc., which are then transformed into various attribute elements through cells as a medium.

Looking at the history and background of the Demon Slayer world, many techniques, such as array techniques, and the tools or items that carry these techniques can be created.

"Go to hell!"

Muzan a wild, out-of-control roar.

Immediately, a large number of monsters swarmed forward and attacked Oboro.

At the same time, the portal behind Oboro, which had completely transformed into flesh and blood, closed instantly, blocking his escape route.

The room was pitch black.

Several large hands emerged from the wall of flesh, grabbed Muzan's body, dragged him into the wall, and disappeared inside.

At this critical juncture, Muzan mustered his courage and seemed ready to fight to the death.

But his instinctive reaction was still to run away!

Ding! A pleasant sound rang out. This sound did not appear in reality, but Muzan heard it.

Because... this is a Melody unique to the soul.

Upon hearing the sound, Muzan and his schizophrenic monsters were simultaneously frozen in place.

The scene in the room looked as if it had been paused.

Oboro... finally released his soul pressure.

Muzan felt as if his soul was naked and abandoned in a vast ocean of raging waves.

He could even sense that at this moment, Oboro could perceive every thought in his mind through the examination of his soul.

He had no secrets from this man.

They have no means to resist.

He could only be swept and battered by the terrifying seawater at will; if he had even the slightest thought of resistance, he would be swallowed up by the sea in the next second.

"Get out of the way."

Oboro only had a fleeting thought.

The deformed monsters that were originally controlled by Muzan's will seemed to have changed masters, retreating to the side in unison.

"Your weak soul was given to Doma and Kokushibo. Sooner or later, they will gradually become familiar with the power of the soul and find the key, just like you, to push open the door to the soul themselves... and then pass this power on to others."

"The power of the soul will spread across this land... and for the two of them, the ultimate goal is to overthrow you."

"Because they know very well that as long as you're alive, the trouble will always be there."

"Your destiny is both connected to theirs and in your own hands."

Whether you survive or not depends on yourself...

"Hurry up and use souls as seeds to build your own forces before they catch up with you... otherwise, when that day comes, your life will also come to an end."

As Oboro spoke, he walked to Muzan, whose entire back had merged into the wall, and slowly squatted down.

Then, he raised a hand and touched Muzan's brow.

"I will take away the most essential part of your essence and blood. Of course, as a reward... I will let you see the 'beautiful scenery' you have always dreamed of."

The Oboro-like fingertips sliced open the skin on Muzan's forehead, causing a stream of bright red blood to flow from the wound.

It may not seem like much, but the 'energy' contained in this little bit of blood is Muzan superior to the quality of the blood Muzan gave to the Upper Moon.

Muzan didn't want to give it, but... his body and soul were no longer under his control.

With the power of his soul, Oboro forced him to relinquish control of his 'self'.

Muzan witnessed Oboro inhaling his blood essence through his fingers.

Then, in the shadows, Oboro, whose face had aged and weakened, began to look young, and his white hair regained its black luster.

Oboro's transformation was not as thrilling as Tanjiro's later transformation.

Because such power is too trivial for him.

As his aura changed, Muzan's mind trembled.

He realized that Oboro in front of him had evolved into the goal he had always wanted to achieve.

Flesh and blood are immortal, therefore eternal.

No longer afraid of the sun...

Even if Oboro's soul power is strong, it is impossible for her to do this.

Because the key point is the Blue Spider Lily.

Oboro clearly knew the whereabouts of the Blue Spider Lily and had already taken it.

In fact, when Oboro appeared in the Infinity Castle, Muzan noticed that some of his cells remained in Oboro's body.

In just a dozen seconds, Oboro transformed back into his youthful appearance.

A moment later, he got up and walked to the door, whereupon the bloodied and mangled wall opened on its own.

Oboro stepped out, and before leaving, he glanced back at Muzan sitting on the ground in the dark light. "If you are the one who survives in the end, instead of them... then I can grant your wish as a reward for you."

Outside the temple is a flat, open area.

Muzan watched Oboro's figure disappear into the distance.

At that moment, the first golden rays of dawn shone down from the distant horizon, landing precisely on Long's body.

Muzan was stunned when he saw this.

Isn't this... exactly what he's always longed for?

"What... do you really want?"

Muzan muttered to himself.

He really... didn't die.

Everyone... everyone is being manipulated by Oboro, him, the Demon Slayer Corps, and all life in this world.

He could sense that Long's words were intentionally driving him to 'move forward' in a certain direction.

Moreover, the stage has already been set for his Final Battle against Kokushibo, Doma, and the successors.

He couldn't refuse, nor did he have the right to refuse.

Considering everything Long has done over the years, this man clearly had premeditated this.

But... what is the purpose of all this? Is it simply to fool the masses and entertain bystanders? "Outsider... in this world, there exists another space that is unfamiliar to you... and another kind of creature."

Muzan said with certainty.

He was not only the progenitor of ghosts, but also a scholar with extensive knowledge in multiple fields.

Although he didn't know where Oboro came from, the fact that this man had appeared meant that... another dimension must exist, but for some reason, he couldn't reach it.

The world as we know it is not the whole world.
