All Heavens: Transcending Dimensions Starting with the Uchiha

The overwhelming paternal love and unwavering determination to protect that surged forth in that instant were like a needle, piercing through the chaotic shell of devouring and instinct within my subconscious.

"No...don't burn down my house..."

Another Kyrian unleashed a Cero, and as the beam struck a vengeful spirit composed of countless charred faces, a flood of shrill cries and images of burning houses rushed into its mind.

Its massive body trembled slightly, and what it emitted was no longer a simple roar, but a faint whimper.

This phenomenon spread like a plague on the battlefield.

The undead in the underworld are souls that have been refined and reshaped under the laws of death. They retain some memories and emotional fragments from their previous lives, but are dominated by the cold will of death.

When the power of the Hollows collides with them, especially when the Hollows' attacks touch these memory cores, those forgotten fragments of past lives are unexpectedly activated and infused into the Hollows' consciousness!

"What...what is this?"

A wielder (not a Espada) who had just torn apart a Death Knight's mount looked at his hands covered in bone fragments, his eyes filled with astonishment and confusion.

Fragments of memories that did not belong to the Hollows but to a human warrior kept flashing through his mind: the vow under the cherry blossom tree, the passion on the battlefield, the unwillingness before death... These clear memories clashed fiercely with his instinct to devour as a Hollow.

On the battlefield, more and more Hollows began to appear, their movements hesitant and their roars meaningless.

Their attacks were no longer purely efficient; their eyes were filled with struggle and confusion.

Some of the weaker-willed Kylian even clutched their heads, emitting painful howls. The power of the void within them clashed violently with the resurrected human memories, causing their spirits to become unstable.

"Hmph, weak!"

Grimmjow swatted away a subordinate whose movements were sluggish due to memory confusion with a single claw, his eyes full of disdain.

But he himself felt a strange sense of irritation as he tore apart a death knight who exuded a strong sense of knightly honor.

High in the sky, Aizen silently surveyed the battlefield, his gaze behind his glasses as sharp as an eagle's.

His powerful spiritual senses clearly detected the unusual "mental fluctuations" on the battlefield and the chaotic state of his subordinates.

The Hogyoku felt slightly warm in his arms, conveying a greed for this world governed by the laws of death, while also keenly analyzing this phenomenon of "memory feedback".

"I see……"

Aizen's lips curled into a knowing smile, not a mocking one, but rather a hint of pleasure at discovering new experimental data.

"The laws of the Underworld grant souls the form of 'orderly death,' preserving the 'remnants' of memories. The attacks of the Void, on the contrary, become the key to unlocking these remnants, stimulating the echoes of 'humanity' that had long been devoured within these 'inferior products' of its subordinates."

He saw chaos, but he also saw something deeper—those phantoms that had regained some of their memories, though their movements became hesitant, had a new kind of "spirit" in their eyes that they had never seen before.

It was a complex will based on memory and emotion, a fighting will that... transcended pure instinct!

A Void that has regained some of its former combat skills and teamwork is far more threatening than a monster that acts solely on instinct.

Beneath this "chaotic" appearance lies enormous potential for enhancing overall combat effectiveness, provided that... it can be guided and controlled.

"Summon all Espada and Legion Commanders."

Aizen's voice calmly reached the ears of every Arrancar below.

Soon, the Espada and key officers gathered at a makeshift "command platform" constructed from giant skeletons at the rear of the battlefield.

They all bore the marks of battle to varying degrees, their expressions differing: Grimmjow was impatient, Ulquiorra was calm, Szayelaporro observed his subordinates still in disarray in the distance with great interest, and Zomalia Lulu stared at Aizen with fanaticism.

Aizen's gaze slowly swept over the crowd, and his invisible authority calmed the commotion.

"Gentlemen, are you confused? Are you puzzled by the unusual behavior of your subordinates?"

Aizen's voice carried an all-knowing composure.

"No need to worry, this is an inevitable phenomenon resulting from our first step into a new world, and it is also... our opportunity to change our destiny!"

He raised his hand, pointing to the smoke-filled, deathly pale battlefield of Bone Plains, as if piercing through space itself, pointing towards Hueco Mundo:

"Did you see that? The souls of the Underworld, after death, did not become those pathetic beings in our Hueco Mundo, struggling in hunger and madness, ultimately devouring each other. They are here, following some cold order, 'existing' in another form. Although they have lost most of their selves, at least... they no longer suffer that endless pain of their souls being torn apart and devoured!"

Aizen's words struck like a heavy hammer against the hearts of every Arrancar.

The eternal hunger of Hueco Mundo, the destiny of devouring or being devoured by companions, the despair of struggling on the edge of madness... these are the painful memories deeply ingrained in the bones of every Hollow, from Gillian to Vastod.

"And what about us in Hueco Mundo?"

Aizen's voice suddenly rose, carrying a mixture of pity (disguised) and anger (guided).

"We are seen as 'evil' by Soul Society and ruthlessly purified by the Shinigami! But who has ever thought about why we became 'Hollows'? It is because our fragile 'integrity' could not bear the pain and obsession of the mortal world and fell into depravity! It is because Soul Society's seemingly fair but actually rigid and corrupt reincarnation system abandoned the 'integrity' who could not enter Rukongai in Hueco Mundo, leaving them to mutate in despair!"

He precisely struck at the deepest pain and resentment in everyone's heart.

Even Grimmjow suppressed his impatience, his eyes turning fierce.

Ulquiorra's eyes flickered slightly.

"We are not inherently evil! We are victims abandoned and distorted by that world, by the order defined by the so-called 'Spirit King's' will!"

Aizen's voice was incredibly seductive, portraying him as the spokesperson and avenger for all Hollows.

"Look here! The Underworld has proven that the fate of souls is not limited to the two tragic ends of purification or becoming nothingness! There is a third path—a path to escape hunger, madness, and the fate of purification! A... a new 'order of death' that we ourselves control!"

He pointed to his subordinates who were still struggling, but whose eyes were beginning to show a glint of "thought" rather than pure "hunger":

"The chaos you see is not a disaster! It is the harbinger of awakening! It is the first cry of the souls of Hueco Mundo to break free from the endless cycle of suffering! The laws of the Underworld are like a key, awakening the 'self' buried by pain and instinct within our fellow beings! Even if it is just a fragment, it is a fragment of hope! It gives us a power stronger than pure instinct—wisdom, emotion, and cooperation! This power will help us conquer this place and establish a new order for the Hollows!"

Aizen's words were like a raging fire, igniting the long-suppressed desires and hatred for the Seireitei in the hearts of the Arrancar.

Even the ruthless Ulquiorra had to admit that the vision Aizen depicted was incredibly captivating.

"Conquering the Netherworld is not just about plunder!"

Aizen's voice was like a divine pronouncement.

"This is to prove! To prove that the meaning of our Hollow existence is not merely to be purified! To prove that we have the ability to establish a new order that is more rational than the Soul Society and freer than the Underworld! This is to save! To save the billions of our compatriots in Hueco Mundo who are still struggling in hunger and madness! To create a paradise for them to escape their fate and find their 'self' (even the self in the form of death)!"

He surveyed the crowd, his gaze behind his glasses filled with a sense of mission akin to that of a "savior":

"This is our ideal! This is the meaning of our battle! For the future of Hueco Mundo, for all our brethren to no longer suffer the pain we once endured! Let this Netherworld become the cornerstone of our new world! Those who are willing to follow me and pave this path of 'redemption' for our brethren, then grip your swords tightly and let the enemy witness the true power of Hueco Mundo—a power that originates from pain and will ultimately transcend pain!"

"For Lord Aizen! For Hueco Mundo!!"

Zomali Lulu was the first to roar wildly.

"So that there will be no more hunger and madness!"

A broken-faced commander, who had just regained some of his memories and recalled the tragic death of his child, roared with tears in his eyes.

"Hmph...that sounds more interesting than just hacking and slashing."

Grimmjow licked his lips, a renewed fighting spirit igniting in his eyes.

"Establishing a new order...an interesting topic."

Szayelaporro adjusted his glasses.

Ulquiorra nodded silently, signifying his approval.

Aizen's speech cleverly packaged a war of aggression into a great holy war to fight for the "redemption" and "future" of the entire Hueco Mundo race.

He exploited the Hollows' deep pain and resentment towards the Seireitei, and took advantage of the "awakening" opportunity brought about by the laws of the Underworld, to successfully transform the individual chaos caused by the revival of memories under his command into a collective fanaticism with a unified goal and even a certain "noble" sense of mission.

Aizen's positioning as a "savior" and his promise of the Underworld as a "new home" had an immediate effect.

Those who have recovered some of their memories and experienced the taste of "awakening," especially the middle and lower-ranking officers, have seen their fighting spirit and efficiency rise rather than fall!

They began to consciously apply the combat skills they had learned in life, and even spontaneously organized simple teamwork.

More importantly, an unprecedented sense of mission has taken root in their hearts.

"We must let more of our fellow Hueco Mundo know! We must bring them here!"

This thought spread through the awakened humility.

During lulls in the fighting, some of the stronger and more determined Arrancar even volunteered to Aizen: "Lord Aizen! Please allow me to return to Hueco Mundo! I want to tell more of my fellow Arrancars the truth about this place, and your ideals! I want to bring them to join this great war!"

Aizen readily agreed and even offered some methods to temporarily open a return portal using the residual power of the beacon.

As a result, small black cavities began to open in reverse from the battlefield of the Underworld, connecting back to different areas of Hueco Mundo.

The departing Arrancar, like fervent missionaries, spread Aizen's concept of "redemption" and the vision of "hope" in the Underworld throughout Hueco Mundo.

Throughout Hueco Mundo, more and more Hollows are drawn to the vision of "escaping the fate of hunger," "finding themselves," and "establishing a new home," and actively pour into the Underworld through these black cavities.

Aizen's army grew like a snowball, increasing the pressure on the Underworld.

Chapter 279, The Tremors of the Soul Society's Seireitei

Such a large-scale spatial anomaly and the unusual gathering of Hueco Mundo's elite forces could not have escaped the Seireitei's monitoring.

Inside the Technology Development Bureau, piercing alarms blared incessantly.

On the massive spiritual monitoring screen, it was clearly shown that multiple and continuous spatial anomalies had appeared in the Hueco Mundo area near Aizen's former laboratory.

Its scale far exceeds any previous large-scale Hollow mass action, and... its direction is not towards the human world or the Soul Society, but towards a completely unknown spatial coordinate!

"Unknown coordinates in another dimension! Energy reaction... with strong death attributes, but the system is completely different! Aizen... what is he doing?!"

Mayuri Kurotsuchi stared at the screen, his eyes flashing with a frantic desire to study and a deep sense of apprehension.

First Squad Barracks.

Captain-Commander Yamamoto Genryusai Shigekuni, leaning on his cane, listened to the report, his brows furrowed, his rock-solid face becoming even more solemn.

Every move Aizen makes signifies a massive conspiracy and disaster.

"We must find out Aizen's movements and objectives!"

Captain-Commander Yamamoto's voice carried an unquestionable authority: "An unknown alternate dimension, a large-scale mobilization of virtual hordes... this threat may far exceed our expectations!"

Just then, Byakuya Kuchiki stepped forward, his cold voice ringing out: "Captain-Commander, this matter involves the depths of Hueco Mundo, and Aizen is exceptionally cunning. Sending a large number of Shinigami to investigate in depth would easily alert him and could also lead to an ambush by his main force. I propose that we send a small, elite team to conduct covert reconnaissance."

He paused, his gaze calmly sweeping over everyone: "Rukia has given her power to humans without permission before, although she has done so before, she is relatively familiar with the human world and the edge of Hueco Mundo."

His sworn brother, Ichigo Kurosaki, is quite powerful and has the ability to enter Hueco Mundo. Moreover, his 'existence' is highly concealed and unpredictable, and he has interfered with Aizen's plans on multiple occasions.

I believe the safest and most effective solution at present is to have Rukia redeem herself through meritorious service, and then form a reconnaissance team with Ichigo Kurosaki and Uryu Ishida (whose Quincy powers are sensitive to Other energies) to investigate the anomaly in Hueco Mundo.

Byakuya's suggestion was reasonable. It gave Rukia a chance to redeem herself, and it also took advantage of Ichigo Kurosaki as a "variable" and Uryu Ishida's investigative abilities to avoid the risks of a large-scale operation.

Captain-Commander Yamamoto pondered for a moment and slowly nodded: "Granted. Rukia Kuchiki, you are hereby ordered to go to the Hueco Mundo anomaly point immediately, together with Ichigo Kurosaki and Uryu Ishida, to investigate Aizen's movements and the truth behind the spatial anomaly! Be extremely cautious, and report back immediately if you discover anything. Do not act on your own!"

"Yes, Captain!"

Rukia knelt on one knee, her voice firm. The opportunity to redeem herself, especially by working alongside Ichigo and the others, filled her with determination.
