They traveled through time at the same time, but the villainous scientist

The war that began in Chapter 449
The next day.

Soul Society, Seireitei.

It was an ordinary afternoon, the sun was shining brightly, and a gentle breeze rustled through the white walls and black roof tiles; everything seemed so peaceful and serene.

The team members patrolled and trained at their respective posts, and everything was in good order, just like every day for the past thousand years.

However, this tranquility was shattered in the next second.

Without any warning, the sky above Seireitei was like a giant curtain, suddenly torn open with a hideous rip.

That was no ordinary portal, but a bottomless black rift that stretched across the sky—a massive "black cavity".

An ominous, chaotic, and violent spiritual pressure, like a flood bursting its banks, poured down from the crack and instantly enveloped the entire Seireitei.

"Woo——!!"

A piercing, high-pitched alarm blared through the sky—the highest level of emergency signal.

Countless figures soared into the sky from the barracks of various squads, staring in disbelief at the apocalyptic scene above.

"what is that……"

A young team member's voice trembled, and his face turned pale.

"Enemy attack! It's a top-level enemy attack!"

The experienced veteran drew his Zanpakuto, cold sweat beading on his forehead.

"Wow...what an amazing spiritual pressure!"

Under the horrified gaze of all the Grim Reapers, countless figures poured out of the black cavity like locusts. They were dressed in white, with shattered masks on their faces, and each of them exuded a terrifying aura far beyond that of ordinary Hollows.

At the very front of the Arrancar army were ten figures. They simply hovered there silently, without even deliberately releasing their spiritual pressure, but the natural presence they exuded was like ten towering mountains, making the Shinigami below almost unable to breathe.

Ten blades.

Immediately afterwards, three figures calmly walked out of the black cavity, the one in the lead being Aizen Sousuke.

He still wore that gentle smile, with Gin Ichimaru and Kaname Tōsen following behind him.

"The entire army is on alert!!"

The captains of the Gotei 13 appeared in their respective areas of responsibility at almost the same time, their expressions extremely solemn.

"Gin Ichimaru...Kaname Tosen...and Aizen!"

Hitsugaya Toshiro gritted his teeth, the veins on the back of his hand holding Hyōrinmaru bulging.

"Wow, wow, this is quite an impressive sight!"

Kyoraku Shunsui pulled down his straw hat, his usually lazy eyes now sharp and piercing.

The battle erupted in an instant.

"kill!"

With a command, the Arrancar legion roared and charged towards the streets and buildings of Seireitei, while the ordinary Shinigami members fearlessly met them.

The clash of swords, the flashes of ghostly magic, and the power of holographic flashes instantly transformed this peaceful city into a brutal battlefield.

Meanwhile, the captain-level combatants tacitly faced off against those ten breathtaking figures.

Soi Fon's figure blurred into a streak as she charged straight at the second blade, Barragan.

Hitsugaya Toshiro's chill met the moisture of the 30th Espada, Halibel.

Byakuya Kuchiki's Senbonzakura then faced off against the Sixth Espada, Grimmjow...

The entire Seireitei has been transformed into a massive, chaotic meat grinder.

While everyone else was caught up in the chaos, Aizen Sousuke, like an outsider, strode leisurely toward the heavily guarded forbidden area in the center of Seireitei.

His goal from the beginning was not destruction, but to reach that supreme throne.

However, he stopped in his tracks.

Not far ahead, an elderly figure stood quietly, leaning on a wooden cane.

He did not release any earth-shattering spiritual pressure, but the air around him was visibly distorted, as if even space itself was bending in front of this aged body.

Captain-Commander of the Gotei 13, Yamamoto Genryusai Shigekuni.

In that instant, all the noise on the battlefield seemed to disappear.

Both the Grim Reaper and the Arrancar felt a shiver originating from the depths of their souls.

It was a kind of scorching heat and awe, like facing the rising sun; it was the purest violence and majesty that had been accumulated over thousands of years of Soul Society history.

"That's enough, Aizen Sousuke."

Yamamoto Genryusai slowly opened his eyes, his turbid pupils burning with a fury powerful enough to incinerate everything.

"Captain-Commander Yamamoto, it's been a long time. You're still as energetic as ever."

Aizen stopped, his smile unchanged.

Before he could finish speaking, Yamamoto's figure suddenly vanished from the spot.

There was no spiritual trajectory of Instant Step, no energy fluctuations whatsoever, just pure speed.

Aizen's pupils contracted almost imperceptibly as he turned to the side, almost instinctively in battle.

boom! ! !
With a deafening crash, Yamamoto's fist grazed Aizen's cheek and landed on the ground behind him.

A terrifying force erupted instantly, and the earth was as if it had been struck by a meteorite. A huge crater appeared with a roar, and spiderweb-like cracks spread wildly. Buildings along the way were directly blown away and crushed by the shock wave!
The mere force of the punch caused a stinging sensation on Aizen's cheek.

He was propelled backward dozens of meters by that overwhelming force, his feet carving two deep furrows in the ground. "Oh dear?"

Gin Ichimaru opened his narrowed eyes a crack, revealing a hint of surprise.

Yamamoto's figure reappeared in front of Aizen, another fist enveloped in terrifying power, already within arm's reach.

too fast.

It's so fast that even thinking has become a luxury.

Aizen was struck by a punch and flew backward like a kite with a broken string, crashing through seven or eight buildings before finally embedding himself deep into the ruins of a high wall, stirring up clouds of dust.

An eerie silence fell over the entire battlefield for a second.

Everyone was stunned by this unreasonable and pure violence.

This is the strongest Shinigami. He doesn't even need to unleash his Zanpakuto; he possesses such world-destroying power simply through his bare-handed fighting.

However, Yamamoto Genryusai's expression did not relax at all. He remained in a punching stance, his gaze coldly fixed on the ruins.

Amidst the smoke and dust, the figure of "Aizen" that had been knocked away shattered silently, like a mirror, turning into countless points of light and dissipating.

Flowers in the mirror and moon in the water.

"What a terrifying force."

A gentle voice sounded behind Yamamoto.

Yamamoto turned around abruptly and saw Aizen standing there unharmed, holding his Zanpakuto in his hand, with that calm and unhurried smile on his face.

"In terms of pure power, you truly stand at the pinnacle of all death gods."

Aizen softly praised, "However, Captain-Commander, power alone cannot change anything."

Before he finished speaking, the Mirror Flower Water Moon in his hand had already transformed into a cold light, aimed straight at Yamamoto's throat.

Ding!
A crisp sound of clashing weapons rang out. Yamamoto had somehow already drawn his wooden staff and used the seemingly ordinary scabbard to steadily block Aizen's slash.

Meanwhile, on the other side of the battlefield, the situation is quietly changing.

"Devour, Devourer of the Void!"

"Soar, Blackwing Demon!"

"Pray, Holy Crying Mantis!"

With each cry of release, the Espada released their Zanpakuto and entered their Resurrección state.

A terrifying spiritual pressure surged into the sky, and figures of various shapes, filled with the aura of death and destruction, appeared on the battlefield.

The captains, who had initially been able to hold their own, were instantly put on the defensive. In the clash between ice and water, Hitsugaya's ice wings were instantly vaporized by Harribel's "Scorching Sea Current";
Byakuya Kuchiki's "Senbonzakura Kageyoshi" sea of ​​blades was also corrupted by Zomari Luna's strange "love" ability, leaving him temporarily restrained.

On the side of death, signs of defeat are already emerging.

"Did you see that, Captain?"

While engaging in a high-speed sword exchange with Yamamoto, Aizen spoke in a calm tone,
"This is the world you protect, so fragile, so vulnerable."

You possess the power to incinerate the sky, yet you are bound by rules and responsibilities, afraid to use it, and powerless to change it.

Has the Soul Society changed at all in the past thousand years?
No. It's just slowly decaying.

Yamamoto's face grew increasingly grim, and he increased the force in his hands, each strike carrying a scorching wind that baked the surrounding ground black.

He never expected that Aizen could gather such a terrifying force in such a short time, and he never expected that he would dare to directly attack Seireitei.

Was it Mayuri Kurotsuchi... that madman, who created the portal that allows him to freely enter and exit Soul Society?

A hint of regret flashed through Yamamoto Genryusai's mind.

In order to keep the Seireitei running, he tolerated too much of the existence of darkness, and now, these darkness have come together and turned into a torrent that is enough to overturn the entire world, and is coming back to haunt him.

Just as Yamamoto Genryusai's heart wavered, another black cavity was torn open in the sky.

But this time, the spiritual pressure emanating from it was neither that of a Shinigami nor a Hollow. It was a power that was a mixture of both, filled with contradictions and a violent aura.

A figure with orange hair leaped out of the black cavity and landed in the center of the battlefield.

It was Ichigo Kurosaki who had entered his Bankai state.

Behind him, members of the Visored, including Shinji Hirako and Hiyori Sarugaki, also appeared one after another.

"Hey, looks like we're not too late."

Hirako Shinji revealed his signature smile, his gaze fixed directly on Aizen.

"Long time no see, have you joined this boring farce too?"

Upon seeing the person who arrived, Aizen's smile deepened.

At that very moment, Ichigo Kurosaki suddenly raised his left hand and covered his face.

"Roar--!"

A roar, inhuman and filled with savagery, erupted from deep within his throat.

Black spiritual pressure surged forth like ink, quickly condensing on his face into a hideous white bone mask with red stripes.

Blurred!

A surge of power swept across the entire area in an instant. Ichigo Kurosaki's figure transformed into a black lightning bolt, instantly bridging the distance between him and Aizen. An ominous black crescent moon condensed on Zangetsu.

"Crescent Moon... Sky Slash!!"
