Bleach: From the moment I was invited by Squad Zero.

However, the shock lasted for less than half a second. Muramasa's instincts and his extreme desire for "Ryujin Jakka" instantly overwhelmed his surprise and doubt.

An opportunity! A once-in-a-lifetime opportunity!

Regardless of how the crack came about or who created it, now that a gap has appeared in the barrier, Yamamoto Shigekuni's mental lock and the barrier's integrated defense will inevitably have their biggest flaw!

"Now!!" Muramasa's eyes flashed with a terrifying light, and he no longer cared about investigating the source of the crack.

He channeled all his mind and energy through the crack, frantically rushing into the barrier and into the depths of Yamamoto Shigekuni's consciousness!

"Listen! The imprisoned flames! Feel the resentment of a thousand years of bondage! Embrace true freedom and destruction—!!"

Muramasa's hoarse roar echoed on the soul level, pushing his abilities to the limit.

It amplifies and ignites the "dissatisfaction," "restlessness," and desire for "burning more intensely" that the Ryujin Jakka sword spirit may have accumulated over the long years!

It worked!

Although it was only a brief contact, I could feel Yamamoto Shigekuni's unwavering will, even amidst the upheavals, stubbornly resisting and attempting to close himself off again.

However, Muramasa's bizarre ability, like the most deadly virus, successfully invaded the spirit of Ryujin Jakka through that fleeting crack.

At the same time, in the instant of the intrusion, Muramasa unexpectedly captured some crucial information about the memory fragments of the "Kuchiki Hibiki" seal.

Scattered information about the exact location, state, and method to break the seal on Kuchiki Hibiki! This is an unexpected and huge bonus!

"Ugh—!" Muramasa groaned, his face turning deathly pale, blood trickling from the corner of his mouth.

Forcibly invading Yamamoto Shigekuni's consciousness, even for just a moment, resulted in a terrifying backlash, severely damaging his mental strength. Yet, his eyes gleamed with ecstatic and cruel light.

He did it! He successfully turned Ryujin Jakka to his side!

Moreover, he obtained crucial information about Kuchiki Hibiki!

However, as he endured the pain and dizziness of the backlash, he once again cast his bewildered gaze toward the "empty" corner from before.

When they tried to find the "invisible hand" that created the crack in the barrier, the place remained empty, with only rocks and shadows, as if everything just now was an illusion.

Deeper into the shadows of the cave, in a place unnoticed by anyone.

Aizen Sousuke's figure slowly emerged from his "non-existent" state.

He pushed up his glasses, his gaze behind the lenses calmly sweeping over the shattered barrier and Ryujin Jakka, who had been turned by Muramasa.

The corners of his mouth curved upwards in a satisfied arc.

"Perfect intervention point, precise force control, just the right timing..." Aizen calmly assessed his "operation" in his mind.

Using the complete hypnosis of "Mirror Flower Water Moon," he placed himself in a state of "absolute non-existence" in the "cognition" of Muramasa and Kuchiki Byakuya.

Then, he secretly broke the barrier. Although Captain-Commander Yamamoto's barrier was very strong, after analysis, Aizen found the weak point and successfully broke the barrier.

"Muramasa... he certainly didn't disappoint me."

"Next, let me see the true power of your 'strongest fire-type Zanpakuto' that has been turned against me!"

"The stage is set up, and the actors... are all in place."

Aizen's figure vanished completely into the darkness of the cave passage, leaving only a whisper that no one could hear, as if it had dissipated with his departure:

"Faced with this rampaging and out-of-control 'Ryujin Jakka', Yanagawa... as the Zero Squad, how will you 'deal with' this... surprise I prepared for you?"

"This is really exciting."

At this moment, deep inside the cave, Ryujin Jakka, who had been turned by Muramasa, was unleashing his terrifying power like an awakened volcano, which began to erupt uncontrollably!

The flames, like a raging dragon with life, crashed wildly against the rock walls, causing the entire cave to tremble violently and melt!

Outside the cave entrance, Kyoraku Shunsui and the others felt the devastating burst of fiery energy, and their expressions changed drastically.

"Not good! Ryujin Jakka... has gone berserk!" Several angry roars rang out at the same time!

"boom--!!!!"

With a deafening roar and a terrifying heatwave, the rock wall at the cave entrance shattered!

Muramasa was the first to rush out; his face was still pale, and there was still blood at the corner of his mouth.

The backlash on his mental strength was clearly severe, but his eyes were burning with an almost manic excitement and a sense of certainty.

Behind him, several figures radiating powerful spiritual pressure followed closely behind—those were the materialized Zanpakuto that he had completely controlled.

Almost at the same time they rushed out of the cave, the captains Kyoraku Shunsui, Ukitake Jushiro, and others, who had been waiting on the perimeter, quickly surrounded Muramasa and his Zanpakuto.

The air was thick with spiritual pressure and a tense atmosphere as the two sides faced off, their tension palpable.

"Muramasa!" Kyoraku Shunsui pressed his hand on the twin swords at his waist and said in a deep voice:

"What did you do to Captain-Commander Yamamoto?! What about Ryujin Jakka?!"

"Captain-Commander? Ryujin Jakka?" Muramasa let out a hoarse, shrill laugh upon hearing this, the sound echoing across the empty wasteland.

"Heh heh heh... Yamamoto Shigekuni? He'll soon be reduced to dust in history along with his prized 'strongest fire-type'! As for Ryujin Jakka..."

"...At this moment, we are overjoyed at its new life and freedom!"

Before he finished speaking, as if to prove his words, a terrifying roar filled with violence and destruction suddenly came from the depths of the collapsed cave!

Immediately afterwards, a towering pillar of fire, like a volcanic eruption, burst through the remaining rock barrier and shot straight into the sky!

Within the pillar of fire, a humanoid silhouette made of pure flames could be vaguely seen, roaring to the sky and radiating a terrifying spiritual pressure and intense heat that could change the color of heaven and earth!

Its mere existence caused the surrounding rocks to melt instantly, and the air to twist and boil!

"That's... the materialized spirit form of Ryujin Jakka?!"

Jushiro Ukitake's expression changed drastically. He could sense just how terrifying the power contained within that fiery body was.

But what's even more terrifying is that the power is filled with an uncontrollable desire for destruction!

"It's out of control!" Retsu Unohana said in a deep voice, a solemn look appearing in her gentle eyes.

The most powerful fire-type Zanpakuto out of control has incalculable destructive power.

"Hahaha! Did you see that? Did you feel it?" Muramasa opened his arms wide, as if embracing the destructive flames, his face filled with undisguised triumph and madness.

"This is the true power of the strongest Zanpakuto! The power that has broken free from a thousand years of restraint and is about to incinerate everything!"

He suddenly pointed at the group of Death Captains in front of him, his voice excited:

"You! Gotei 13! Today, turn to ashes under this 'strongest' flame! No one can stop me! No one can stop Ryujin Jakka!"

Chapter 150 The Burning of the City

However, the moment he finished speaking—

A sword cry that seemed to command all the fires in the world came from the direction of Ryujin Jakka!

Then, to everyone's astonishment, an enormous wall of flames enveloped everyone inside!

Its flames seemed to have a life of their own, slowly flowing and swirling on the barrier, emitting a terrifyingly high temperature that burned even the soul!

The interior space was instantly heated to an unimaginable degree, the air distorted like water ripples, the ground cracked and melted, and even ordinary Grim Reaper team members found it difficult to breathe, their protective spiritual pressure rapidly depleting.

"This is... Ryujin Jakka... Burning the city?!" Shiba Isshin exclaimed, his face filled with disbelief.

As a user of a fire-type Zanpakuto, he was very familiar with the power of "Shanyue," but the fire power contained in the burning city before him far exceeded his imagination!

"Not bad!" Muramasa stood at the edge of the barrier, laughing wildly, his voice echoing within the enclosed space of flames.

"This is the power of Ryujin Jakka! Once trapped inside, if you try to force your way out from the inside, it will trigger a violent counterattack of flames, subjecting you to extreme high temperatures of over 6,000 degrees Celsius!"

Even captain-level spirits can't hold out for long! And you..." His cold gaze swept over the trapped Grim Reapers,

"Become the first sacrifices to this newborn flame, and slowly turn to ashes here!"

"Don't move!" Mayuri Kurotsuchi's voice rang out, tinged with seriousness.

"This flame barrier is not just high temperature; its spiritual energy structure contains a certain rule of 'rebound,' and brute force attacks will only provoke a stronger counterattack."

Six thousand degrees... Hmph, the data is astonishing, but it's not necessarily unsolvable. We need to analyze its spiritual energy nodes..."

Kyoraku Shunsui, Ukitake Jushiro, and the others looked even more grim.

They could sense that the "Burning City" barrier not only sealed off the surroundings, but the high temperature inside was also continuously consuming their spiritual pressure and physical strength.

Even more troublesome is that Ryujin Jakka's true form seems to be lurking and roaring outside the barrier, poised to launch an even more ferocious attack at any moment. And Muramasa…

"Muramasa! Are you trying to escape?!" Soi Fon keenly noticed that Muramasa and Byakuya Kuchiki beside him seemed to be preparing to leave.

"Escape? No, we're just going to do something more important."

Muramasa stopped and glanced back at the grim-faced Shinigami trapped in the flame barrier. A cruel and gleeful smile crept across his face.

"As for you, just enjoy Ryujin Jakka's 'warm hospitality'."

When I return from the mortal realm, perhaps I'll still see your ashes... If there are any ashes left then, hahaha!

After saying that, he ignored the angry shouts of the Shinigami and left the place with Kuchiki Byakuya. Ryujin Jakka did not stop them.

"Don't even think about leaving!" "Stop him!" Several Grim Reapers attacked simultaneously, attempting to use ranged attacks or binding spells to intercept him.

However, their attack was thwarted by the flames of "Burning the City," and they could only watch helplessly as Muramasa and his party disappeared completely from sight.

"Damn it! He got away!" Shiba Isshin slammed his fist into the scorching ground, sending sparks flying.

“The present world… Karakura Town… He really is going to break the seal on Kuchiki Kyouga!” Ukitake Jushiro coughed, his face flushed from the high temperature and anxiety.

"There's no use talking about this now!" Kyoraku Shunsui pressed down on his straw hat, scanning the surrounding flame barriers radiating deadly heat and the gigantic humanoid figure of fire beneath the brim.

"If we don't deal with this 'big problem' right now, let alone catch up with Muramasa, we'll be in trouble if we can even get out of here alive!"

"Is this... the strongest fire-type Zanpakuto, Ryujin Jakka?"

Soi Fon felt the terrifying heat that was everywhere, and even she felt a pang of fear.

A mere skill designed to trap the enemy left their captains helpless, even their counterattacks were met with heavy losses. If its true form were to launch an attack…

A shadow fell over everyone's hearts. Muramasa's arrogance was not unfounded; having mastered the power of Ryujin Jakka, he certainly had the right to be arrogant.

They are currently trapped in this deadly cage of flames, enduring the continuous scorching heat, and also facing the out-of-control fire demons outside the barrier that are watching them intently and could attack at any moment.

Without dealing with Ryujin Jakka, they cannot leave this place, nor can they stop Muramasa's plot to go to the human world.

At this moment, there are the spirits of Katen Kyokotsu, Sogyo Risa, Nikushizuki, and several other Zanpakuto with considerable strength.

Instead of attacking the trapped Grim Reaper, they followed Muramasa away from the area.
