I'll kill you after I finish this game!

"Ugh——!"

The roar of the monsters echoed through the sky, and the power of the God-Slaying Tool, the creation of monsters, manifested once more!

This is about creating various magical beasts through imagination; the stronger the imagination, the more diverse the magical beasts created.

Kokushibo gripped the Demon Blade tightly in his hand, his eyes fixed on the imposing demonic beasts around him, his heart sinking to the bottom.

It seems this time, it's going to be a fight to the death.

P.S.: Please vote and recommend. There are quite a few people on the forum who want to read about time travel, but it's easy to get involved in that kind of thing, so they all remind me to be careful if I write about it.

I remember Hedgehog Cat had a really popular chat room called Mrs. Lie, though I didn't really watch it...

Chapter 73 The Collapse of Causality! Neptune's Dissatisfaction

"Damn it!!! Damn it all!! These damned rebels!!!"

Muzan Kibutsuji, who was leisurely watching the battle from the Infinity Castle, was enraged when he saw his demons being crushed and annihilated at a visible speed.

Even the Twelve Demon Moons of the past are losing their blood ties with him one by one.

The beautiful women clad in steel armor displayed abilities that were not part of Blood Demon Arts, shocking and enraging Muzan.

At this moment, Muzan exuded an immense aura that made the surrounding space groan, and his eyes were bloodshot with boundless rage.

What was originally an attack with a fairly high success rate has now resulted in extremely heavy losses for him.

Moreover, all the fighting power and effort he had accumulated over the past hundred years was about to be completely destroyed.

Large swathes of Japan are no longer under the control of Muzan's demons; humanity has begun an organized rebellion against him. Even the notifications from his supernatural treasure system have made Muzan's mood sour...

[Ding! An abnormal situation has been detected in this world. Please proceed with further action. 8@＃U$*＆@$@＃*@@@........]

"What exactly is going on!?"

Seeing the jumbled gibberish on the interface that only he could see, and the cold system notification in his mind turning into a muffled crackling sound, Muzan's face immediately turned extremely ugly.

This is the extraordinary treasure that transformed him into the perfect being he is today! How could such an unknown situation occur at this time?!

Heartache, anger, hatred, unease, and many other emotions were mixed in Muzan Kibutsuji's heart, but the greatest fear was of the unknown and uncontrollable situation.

"So the problem was with you after all, you scoundrel Muzan..."

A sudden exclamation came from not far behind Muzan Kibutsuji, causing Muzan and Nakime beside him to widen their eyes.

"What the hell!?"

Muzan and Nakime turned around and saw a boy with black hair, blue eyes, and a somewhat eerie smile on his face.

Reiji's eyes gleamed, and the power of Nep within him automatically surged into his eyes, allowing him to clearly see the true nature of Muzan, inside and out, as well as the foreign object residing within Muzan's body.

When Muzan opened the Infinity Castle portal, Reiji already knew Muzan's coordinates. After arriving there, Neptune immediately released another force to interfere with something.

Now it seems that it must be that thing inside Muzan's body.

Moreover, Raiji also sensed an aura emanating from Muzan that was attractive to him.

That looks like... the Blacklight virus?

Lei Zhe sensed the slight reaction of the cells within his body and was certain that Muzan's body contained a viral progenitor that had evolved in a different direction.

"Tsk tsk, I really don't know if the standards for cheating have been lowered these days, even someone like you gets approached by the system."

After confirming that Muzan was the singularity of this world, Reiji revealed an amused smile and said.

The words he uttered immediately made Muzan's eyes widen.

Why would he do that?!

"!!"

Muzan suddenly bulged out his eyes, his vision receding rapidly, and his once-decent face immediately collapsed.

"Hey!"

At this moment, the sound of the floor cracking finally broke the silence, and Raize took the initiative to test Muzan.

Ignoring Muzan's words, he swiftly channeled his monstrous strength—enough to sink an island—into a single point and slammed it into Muzan's face.

"pound--!"

The late-arriving sonic boom cloud exploded, forming a terrifying gale-force wave that swept over Nakime, who was still unable to react, shredding the defenseless demon's body into minced meat that scattered everywhere.

Boom boom boom boom boom boom—!

Muzan's body, like a train, crashed through paper doors and walls at a terrifying speed.

The fist that could have sent Muzan flying over a hundred kilometers lost its terrifying power midway through the fight, disappearing without a trace as if it had sunk into the sea, much to Raizer's interest.

Blood Demon Art? No, that doesn't seem like it at all... It's caused by the other person's unique physical characteristics!

"You bastard! Whoever you are, die!!!"

The dents on Muzan Kibutsuji's face healed in the blink of an eye, his original black hair suddenly turned silver, and his pupils turned a strange dark gold.

The guy opposite him who attacked him and knew his secrets was undoubtedly an enemy, and Muzan could sense that.

Moreover, the power in the opponent's fist was beyond human capabilities. Muzan dared not be careless in dealing with this unknown enemy and used all his strength to annihilate Raize.

With a ferocious and malevolent expression, he swung his fist at Lei Zhe, as if the immense and terrifying power within him had found an outlet, which was then unleashed through his fist.

“Rumble——!!!”

The materialized energy fluctuations, like a tsunami, transformed into pillars of light, destroying buildings along the way in Infinite City with earth-shattering force, and roared toward Reiji.

The destructive power of Muzan Kibutsuji's attack far exceeded that of Raizel's previous strike. Raizel, with a pleased smile on his face, charged forward without any fear, raised his hand and formed a blade with his palm, unleashing a Heavenly Demon Crimson Blade filled with killing intent.

laugh--

The terrifying beam of light unleashed by Muzan was sliced ​​in two, and the resulting distorted power created a terrifying wave that swept in all directions.

Rumble!

The entire Infinity Castle was collapsing and shaking violently. Reiji himself, amidst Muzan's wide-eyed stare, sliced ​​through Muzan's energy pillar with lightning speed and stood face to face with him at close range.

"It seems you're indeed no match for those Demon Slayer Corps guys, but is that all there is to it?"

With a light laugh, Reiji sensed Muzan's extraordinary strength. Muzan's Absolute Domain power had been reduced to eighty percent, and he unleashed a series of Yata no Crow attacks.

Raiji's hands danced in front of Muzan, their blood-red, ferocious claws slicing through Muzan's body like chainsaws.

puff puff!

His powerful body was torn open, leaving a bloody gash, and the tangible killing intent emanating from the claws inflicted even more pain on Muzan.

"Ahhh!!!"

Muzan's face contorted in agony, and for the first time, he let out a scream.

But Lei Zhe narrowed his eyes and sensed that something was wrong.

The moment his first punch landed on Muzan, he knew how strong Muzan's physical abilities were. Logically, his Yagami-ryu technique should have torn Muzan's body apart on the first strike.

However, when Raiji's powerful martial arts technique struck Muzan, its force was reduced by nearly 90%, and the remaining 10% was insufficient to completely destroy Muzan's body.

"Get out of my way!!!"

Muzan roared, and another massive, tangible shockwave erupted from his body.

Like an enhanced version of Pain's Shinra Tensei in Naruto, the shockwave unleashed by Muzan exploded for hundreds of meters, turning the Infinity Castle into a ruin-like environment.

"I see, it can absorb kinetic energy... no, it should be all energy."

Raiji was affected by the shockwave from Muzan, but he was completely unharmed. A look of understanding flashed in his eyes, and he immediately saw through the secret of Muzan's body.

"So what if you know?! The perfect me is invincible!!"

Muzan grinned and raised his hand. A ball of fire, the size of a basketball and resembling a miniature star, was held by Muzan. The fireball contained a temperature of 15 million degrees Celsius, which made Reize raise an eyebrow.

This is equivalent to the terrifyingly high temperature inside the sun; if it were to erupt on Earth, it would be enough to vaporize and evaporate everything.

Muzan not only overcame the weakness of the sun, but his arrogant and conceited nature made him feel as if he were holding the sun in his palm. Even though he hadn't become a god, he already considered himself one.

The sphere of fire floating above his palm seemed to be Muzan's authority, proudly and arrogantly proving his power and perfection to the world.

Look! I, Muzan, have not only conquered the sun, but I also possess power that rivals the sun!

Muzan's ability to absorb all energy is also a reward from the system.

That was a superpower from the mutant Black King Sebastian Shaw.

Its power characteristic is that it has the ability to absorb all forms of energy and convert them into its own energy, and it can release the energy.

Muzan can absorb kinetic energy, solar energy, electrical energy, and even nuclear energy. While he was happily basking in the sun, he was also storing and compressing a lot of energy in his body.

He possesses many Blood Demon Arts superpowers. The flame-type Muzan devours the demons he creates, constantly fusing them and extracting their essence while discarding their dross.

The all-encompassing and fusion nature of ultimate life forms allowed Muzan's evolution speed to accelerate at a rocket-like pace.

Now he possesses the power to do whatever he wants on Earth.

"Oh~, that's pretty good power, why don't you unleash it?"

Reiji smiled merrily at Muzan's gloomy face and raised his hand, indicating that Muzan could directly unleash the flames that were enough to evaporate everything.

"court death!"

Muzan was furious when he saw Raiji's indifferent and contemptuous face. That kind of expression should only appear on him to others. How could he allow a lower-class creature to look at him with such a face and eyes?

Muzan Kibutsuji hurled his little sun at Raize, then grinned maliciously before disappearing silently into the Infinity Castle.

Muzan Kibutsuji instantly teleported away, fully aware of the destructive power that would follow.

In an instant, Muzan teleported to a location a hundred kilometers away. Standing near the coast, he looked out at the distant sea with a disdainful gaze.

In the distance, under the pitch-black night sky, the sea level in front of Muzan suddenly dropped by more than a meter, and a blinding and intense light appeared ahead.

That was the intensely hot light of flames, the light that wiped everything away.

The Infinite City alternate dimension lies beneath the deep sea, and the world seems to have frozen in time.

The brilliant flames raged across the sky, cleansing the earth, clearing away the clouds, and rapidly evaporating the boundless seawater.

At that moment, pure white and blazing firelight filled everything, annihilating all of it.

A few seconds later, or rather, tens of seconds later.
