Muzan Stood Up

Soul!

From the moment Mireimaru came into contact with Oboro, Muzan became very concerned about those two words.

He had a vague feeling that the secret about that man was related to the soul.

Why is it that after turning a person into a ghost, the other party can ignore the control of their own blood?

He was more concerned about this point than what method Oboro used to transform into a demon.

Without this bizarre detail, all the inheritors today would be like the ghosts under his command, following his every command.

Muzan has been living a very frustrating life these past few years. The successor wants to hunt him down, and the Demon Slayer Corps is also searching for him everywhere.

This made him dare not show his face at all. Of course, what he feared most was Oboro.

The Ubuyashiki Clan had long been aware of Oboro's intentions, Muzan had also noticed them... He was constantly collecting everything related to Oboro.

And today, he finally succeeded!

In the Infinity Castle, the three Upper Moons, Kokushibo, Akaza, and Doma, are gathered together, along with Nakime holding a biwa (a traditional Chinese lute).

Under their watchful eyes, Muzan was inserting his fingers into the skull of a successor.

Blood flowed from the other's brow, and his body trembled violently, Muzan closed his eyes.

Deep within his consciousness, Muzan once again saw that familiar, blurry figure, the soul power of Oboro remaining in the blood of the inheritor.

It's also a regret.

Staring directly at the obscure shadow in front of his mind, Muzan felt a terrifying pressure on his soul. Even though it was just a lingering remnant, the impact and fear it caused him were the same as when he first experienced it, making him feel uneasy and apprehensive.

However, he has neither escaped nor returned to reality, nor severed his mental connection.

Because, after countless attempts, Muzan finally sensed his own 'ideology,' which is his soul.

From initially observing Oboro's soul without daring to move a finger, to now being able to calmly gaze into its eyes, it took him a full century. Before this, Muzan didn't know what a soul was. From his perspective, he thought it must be related to an individual's spirit or will. He could guess that, but he couldn't truly feel it.

Without sensing the 'form of the soul,' he was unable to attack Oboro's will.

After countless attempts, he finally pushed open this mysterious door. Unlike the first time when it only appeared in his mind as an 'image', Muzan can now concentrate his scattered thoughts, form his own soul image, abandon external physical perception, and reach a deeper dimension of life.

For this reason, over the past century, he has searched far and wide, explored many avenues, and conducted extensive research in biology, trying to create methods to strengthen his own spirit.

Although he hasn't yet developed a systematic training method, he's no longer a complete novice.

Each time he touched Oboro's soul, he gained a lot, even though the process was very painful.

The more Muzan understood this power, the Muzan obsessed he became, because he discovered the horror of the soul.

This power is a far more transcendent existence than his blood.

He even had a feeling that the power of the soul... did not belong to this world.

The soul has always existed in the world, but it is elusive and no one in this world can truly develop it.

He lived longer than Yoriichi Tsugikuni, over a thousand years, so if anyone knows more about the origin and evolution of this world than him, he dares to say he is second, and no one can say he is first.

He became increasingly curious about Long.

How did this man even appear?

And who created this power? "I've had enough of your gaze..."

Muzan stared at the illusory figure in front of him with his crimson eyes and said coldly.

He still couldn't make out Long's face, but the familiar gaze from the shadowy figure made the veins on his forehead bulge.

This time, he can finally retaliate.

After speaking, his right fingernails suddenly grew larger and immediately swung towards Long's lingering resentment.

With a whoosh.

As the sharp light swept past, Oboro's soul was instantly torn to pieces, dissipating like smoke and vanishing without a trace.

Hahahaha...

Seeing Oboro's will being eradicated, Muzan felt an unprecedented sense of accomplishment, which immediately made even the usually cold-faced man smile.

"Even if you created a method for cultivating soul power and didn't leak it out, you shouldn't provoke me. What I can do is beyond your imagination... At least, from the perspective of biological evolution, I am the most perfect in this world."

Muzan whispered excitedly.

Long underestimated him.

He is the progenitor of demons, the ultimate life form unlike any other species. Just because others cannot do something does not mean he cannot.

Even without instruction, he can touch the soul and gradually master this power.

"It's time for you to pay the price."

As soon as he finished speaking, Muzan's consciousness returned to his body, and he opened his eyes in reality, pulling out the finger that had pierced the inheritor's brain.

The inheritor fell to the ground.

Muzan merely glanced at it, and the next second, the inheritor's flesh swelled up and burst open like a balloon.

If Oboro's will is eliminated, then as the successor of the demon, he can be slaughtered at will.

With just a single thought, the cells in its body can multiply indefinitely, eventually breaking apart.

The upper moons in the distance had different expressions.

Akaza looked surprised.

He had gone to great lengths to capture this successor, and had even been injured in the process... He was well aware of the successor's level.

Furthermore, as Muzan's subordinates, the Twelve Kizuki have all learned about the events of the past few years, and it seems that Muzan has no way to deal with the successors.

Now, this balance has been broken.

"Something interesting seems to be about to happen."

Standing beside him, Doma smiled slightly.

As time passed and their physical bodies recovered, they broke free from the Blood Demon Art that Oboro had placed on their brains, and remembered their past 'nightmare'.

Muzan slowly turned around and stared at them.

When his gaze swept over him, even Kokushibo couldn't help but hold his breath, as if in an instant, he heard extremely brutal and dense roars, causing his mind to tremble violently.

This is... an auditory hallucination caused by mental pressure.

As for Akaza and Doma, their limbs instantly stiffened like stone sculptures, as if even their thoughts had been frozen.

Lord Muzan... has become different.

"That God of Imperial Martial Might... heh... he's still alive. I want to see him... he has something that interests me." Muzan smirked and muttered to himself.

Outsiders may not know who the legendary God of Imperial Martial Might is, but how could they not know? After saying that, several huge fleshy lumps suddenly bulged up from the shadows around Kokushibo and the other two, and several tentacles shot up, piercing into the necks of the three Upper Moons like needles, and began to inject large amounts of blood.

"I bestow my spiritual power, along with my cells, upon you... Be reborn from the ashes, and then go and find him."

Muzan spoke coldly, word by word.

As blood was injected, the three Upper Moons became dazed and their faces contorted, with Akaza and Doma convulsing incessantly.

Dense veins appeared on the skin's surface, pulsating like tiny snakes.

Muzan wanted was not just the secrets about the soul that Oboro possessed.

And... the Blue Spider Lily he had always longed for.

Because... that man must know something.
