Starting in The Boys to Become the Ultimate Lifeform.

167. Chapter 167: Muzan, Nearly Insane! A Foul Demon's Feast!!

It turned out her worry was not unfounded.

"Hiss..." Muzan turned his head to look at the wound on his left arm. Wisps of white smoke rose from between his fingers, and the intense, lingering burning sensation contorted his face in pain.

"Useless, all of you are useless!"

Muzan roared in a low voice, his facial muscles spasming continuously from the pain.

Splatter! Thick, crimson blood slowly dripped from the tip of his right finger onto the wooden floor.

Tap tap tap... Muzan's eyes were blood-red, and his teeth ground together. As his bluish, sharp fingertips sank into the flesh and blood above his left arm, soon, with a tearing sound, large chunks of burnt flesh and blood, mixed with streaks of blood, were flung in front of Nakime.

Nakime, kneeling on the floor, didn't even dare to look. She trembled all over, her single eye, hidden by black hair, filled with panic and fear.

"Get up!" After tearing off the damaged flesh and blood, new flesh and blood began to sprout from Muzan's left arm. Although the pain somewhat decreased, his inner anger intensified.

Nakime, holding her biwa, tremblingly stood up. She lowered her head, not daring to make a sound.

Bang! A left hand instantly pinched her neck, lifting her into the air. A current of air formed by anger wantonly destroyed the surrounding wooden rooms.

"Reason?!"

Facing Muzan's questioning.

Blood seeped from the corner of Nakime's mouth. As the strength in Muzan's hand continuously increased, darkened bulging veins like a spider web spread upwards from her jaw until it covered half her face.

Her large pupil burst with streaks of blood at a speed visible to the naked eye. "Gurgle..."

Because her mouth was filled with blood, Nakime was unable to make a sound.

Seeing this, Muzan slightly loosened his hand.

Only then did she have a chance to speak.

"Infinity Castle... the speed of movement is too slow... gurgle." Blood continuously surged from Nakime's mouth. Forcing back the pain, she continued, "It's all my fault... Master."

"It's not your fault? Could it be that my decision was wrong?!" Muzan's expression was cold and sinister.

Nakime knew Muzan could pry into the hearts of demons; how could she dare think otherwise?

"Master's decision is not wrong. It's that I couldn't keep up with Master's pace and delayed the opportunity." Nakime knew Muzan's personality very well. If she didn't take the blame herself, then she would be the next to die.

"Consider yourself somewhat self-aware."

Muzan used his other hand to brush aside the black hair covering Nakime's eyes. Just when Nakime thought she had escaped death.

Suddenly, Muzan's fingertips exerted strength, directly stabbing into her neck.

The sudden intense pain nearly suffocated Nakime.

But soon, she felt a stream of cold liquid continuously pouring into her body.

Gurgle... gurgle. Bulging veins protruded and writhed on the back of Muzan's hand. As the blood vessels continuously contracted, a large amount of blood flowed along his fingertips into Nakime's body.

"Hantengu is dead. You will take his place." Saying this, Muzan raised his right hand and, with his sharp index finger, carved the characters [Upper Rank Four] into Nakime's eye. The entire process was extremely painful, but fearing it would displease Muzan, Nakime didn't make a sound the entire time.

After Muzan finished carving the characters.

She fell to the ground. Splatter! A large amount of blood and fragments of her tongue were spat out by her.

"Summon all the Upper Ranks to me!"

Muzan didn't even glance at Nakime out of the corner of his eye, and sat alone on a chair, closing his eyes tightly, checking the damage within his body.

Nakime picked up the biwa from the ground with trembling hands.

"Plink plink..."

The melodious and crisp sound of the biwa, like ripples in water, spread outwards. In an instant, the buildings centered around her began to flip and fold.

Swish!!

Figures suddenly appeared in various parts of the Infinity Castle.

In the Northeast direction, Lotus District, a figure with white-oak colored hair and smiling eyes stepped from the air onto a short bridge. He lightly fanned himself with an iron fan in his hand, on which were carved several blooming white lotuses. "How surprising. That Hantengu fellow was actually killed."

Although he spoke of accident, the expression on his face didn't change at all.

A gentle smile hung on the corner of his mouth.

But the next second, space flickered, and he vanished from the spot.

In the Southeast direction, inside a dojo, a man with peach-pink short hair and his upper body covered in dark blue tattoos was punching the air. His red short-sleeved shirt was open, revealing his muscular body. Bang! Every punch he threw caused the air to explode.

"Chaotic Style, Empty Style, Leg Style, Shattering Style, Destroying Style, Final Style."

The man's attack was precise and rapid. In every move was his understanding of ancient martial arts. As the final style fell, the entire dojo and the stone slabs on the ground were completely destroyed. After hearing the floating biwa sound, his feet, adorned with prayer beads, stepped on the scattered wood and tiles and walked towards the center of the Infinity Castle.

On the way, a colorful pot painted with floral patterns just happened to roll in front of the man.

With a clang, the colorful pot bounced up and stood upright on the wooden floor.

"Oh my, oh my, what a coincidence. It makes me so happy to see you're still so energetic. Truly delighted. Speaking of which, it's been almost ninety years since we last met, hasn't it?" A wisp of black smoke emerged from the mouth of the pot and quickly condensed into a physical body. His entire body was white, and his appearance was quite bizarre.

One could see his mouth was located where his eyes should be. His green lips opened and closed.

Akaza ignored Gyokko and continued walking.

The corridor in front of him was like a Rubik's Cube twisting randomly. Soon, he and Gyokko arrived at the center of the Infinity Castle.

"Master Doma, it's truly a pleasure to see you." Gyokko had a vertical yellow eyeball on his forehead. On it were carved the characters for Upper Rank, while his other eye was on his tongue, the characters within it were Five!

"Gyokko, this new pot you've got looks quite good. Didn't you give me a pot before? I used that pot to plant a woman's head. I have to say, it makes a fantastic decoration." Doma laughed heartily.

Under the light, his pupils were actually rainbow-colored. On the left and right, respectively, were carved the characters for Upper Rank and Two.

"Pots aren't meant for planting human heads... However, it seems doing that isn't so bad either." Although Gyokko was a little unhappy, in his opinion, his pots were the most beautiful works of art in the world. How could they be used for anything else? But then he thought again. A beautiful woman's head resting on the mouth of the pot must be quite excellent.

Thinking of this, several pairs of small arms extended from his neck, applauding Doma's brilliant creativity. "Masters, I'm not late, am I?" A fellow with messy, grass-green hair pushed aside a wooden door and walked out from it. The color of his skin was light gray, and he was extremely thin, especially his waist, which was only about a fist's width, as if it would break if the wind blew on it.

His appearance was relatively ugly, with black spots covering his face and body.

"Ah, it's Gyutaro. I think this is your first time coming to the Infinity Castle, isn't it?" Doma said with a smile.

"That's right, Master Doma."

Gyutaro was especially respectful towards Doma because it was Master Doma who saved them when he and his sister were at their wit's end and stepped in and saved them. He and his sister Daki coexist. Generally speaking, he usually fuses into Daki's back and only appears when Daki is in danger.

But now it's different. Facing the summons from that master, Gyutaro took it quite seriously.

"Oh right, does any of you know how that Hantengu fellow died?" Doma very familiarly put his arm around Akaza's shoulder.

"Let go."

Akaza said expressionlessly.

"What?"

The next second, Akaza punched him in the chin. As a mouthful of blood sprayed out, several cracks appeared on Doma's chin. But Doma didn't care. The smile on his face never disappeared. "Yo-ho, your strength seems to have increased a bit. You haven't been secretly eating women behind my back, have you?"

Because Doma felt that the nutrients contained within females could even allow them to conceive a baby, he believed that females were much more nutritious than males.

Thus, Doma liked to consume females for no other reason than to quickly become stronger.

Furthermore, he also had a cabinet specifically for displaying beautiful heads.

Akaza, on the other hand, was completely different from him. After becoming a demon, he lost all his memory, leaving only the obsession to become stronger in his heart. In order to continuously become stronger, he became someone who only liked to fight against the strong and even utterly detested the weak. At the same time, based on his adherence to the strong's creed, he never killed or ate women. Furthermore, only when he was extremely hungry would he choose to eat people to fill his stomach.

So he and Doma were considered two extremes.

Towards the other's behavior of only consuming the weak, Akaza felt deep contempt.

Therefore, his relationship with Doma was not good. In fact, one could say it was very bad.

"I don't know. Perhaps he was surrounded and attacked by those few Hashira. One certainly wouldn't be enough. I think the entire Demon Slayer Corps must have mobilized. Otherwise, master wouldn't have urgently summoned us," Gyokko guessed.

While they were talking.

A wooden screen slowly slid open. Nakime, holding her biwa, appeared before everyone.

At this moment, her injuries had completely recovered. Only on her pale blue and translucent hand back were there still some bulging veins twitching.

This was because she hadn't completely digested the demon blood Muzan injected into her body. That blood contained immense energy.

If it were an ordinary human, or a foul demon not among the ranks, after continuously receiving a large amount of Muzan's blood, their body simply couldn't withstand the speed of mutation, leading to cell collapse.

Fortunately, Nakime's own talent was good, and she had absorbed Muzan's blood before, so she could barely withstand it.

"Biwa Woman, where is that fellow?" Akaza said coldly.

"Master Upper Rank One was the quickest to reach the center. He is currently being received by Master Muzan."

As soon as Nakime finished speaking.

The house above everyone's heads instantly inverted.

"This..."

Gyutaro and a few others looked up together. Unexpectedly, the scene they saw made his pupils tremble violently! They saw a figure kneeling on the ground was actually pierced through the chest by a blood vessel. A crimson, writhing blood vessel emerged from Muzan's palm.

The figure wore a kimono with purple snake patterns interspersed with black patches. His dark red long sideburns covered the back of his neck. The long saber tied at his waist, crafted from his own flesh and blood and bone, the blade was covered in bizarre patterns and orderly arranged eyeballs.

Master Muzan is actually transferring his own blood! Even a trace of astonishment flashed in Akaza's eyes. The strength of the Upper Ranks, especially Upper Rank Four and above, it's already difficult to become stronger by absorbing blood.

Unless the quantity is exceptionally large. But ordinarily, how could Muzan possibly infuse them with large amounts of blood? This is simply too abnormal. What on earth did Master Muzan experience recently?!!

"Hmph!" Suddenly, Kokushibo, with his six eyes tightly closed, a large amount of bulging veins surged on his face. His surface muscles slowly expanded. The dark red patterns on his neck and face, driven by the movement of the skin, appeared particularly ferocious and twisted.

"Master, it's the limit." On both sides of Kokushibo's face, six eyes with blood-red sclera and golden-yellow irises simultaneously opened. These three pairs of eyes almost filled his entire face, while in the left and right eyes in the very center, were carved, respectively, Upper Rank and One.

Whoosh! The blood vessel in the air was instantly retracted by Muzan.

Although he contained a large amount of blood within his body, he couldn't withstand such consumption. However, if his plan succeeds, then this amount of blood is nothing.

The blow and sense of defeat Xia Shang brought to Muzan this time was simply too great.

In order to obtain the Blue Spider Lily and kill Xia Shang, Muzan was already nearly insane. The first sentence he spoke after shifting his gaze towards the others startled everyone greatly.

"Three days later, I will have Nakime move the Infinity Castle underground in Tokyo Prefecture. The millions of people living inside will fall into the Infinity Castle and become my blood food. During this period, my blood will turn into a blood rain. I want to see how many foul demons I can create!" Muzan understood that even using quality might not be enough to kill the opponent.

Since the opponent's recovery ability is not strong, it's better to use endless foul demons to slowly wear down the opponent's strength.

Furthermore, by then, I will have millions of blood food to recover my stamina.

Inside the Infinity Castle, sunlight cannot shine in. Inside, it's almost impossible for him to die!!

"Master... You plan to kill everyone in the entire Tokyo Prefecture?" Although Gyokko was a psychopath, he had never thought of such a heinous action. Millions of people. Capturing them one by one would take a very long time.

"Can the Infinity Castle expand to such a large range?"

Akaza also didn't quite approve of Muzan's action, but he didn't say so explicitly.

"No."

Muzan replied.

"But don't forget, the Infinity Castle can move. In one day, the range it passes through is enough to cover the entire Tokyo Prefecture." Muzan's purpose in doing this was very simple. He wanted to use the lives of everyone in the city to threaten the Demon Slayer Corps and the Nihon Government to help him find the Blue Spider Lily and hand it over to him.

If he could obtain the Blue Spider Lily, then he would stop the action. One could say his purpose since becoming a demon has never changed.

That is to overcome his last flaw and become an undying and immortal perfect creature.

If he doesn't get it, his plan will proceed normally.

In Muzan's view, as long as he devours Xia Shang, he can still gain the ability to resist sunlight.
