Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 286 Items that Break Dimensions

As the crystal completely integrated into Sleep No. 8's body—

The once calm, pale green nutrient solution began to ripple with constant vibrations.

From the very beginning, Aizen had already planted a time bomb within this perfectly cooperating life form.

Virtualized factors.

Glug... Glug...

The nutrient solution began to boil, the originally clear liquid turned turbid, and a dark red color began to spread inside the chamber.

The sleeping beauty, curled up, suddenly began to tremble violently with her eyelids.

Beep—beep—beep—!!

The alarm lights in the laboratory flashed, and a piercing buzzing sound shattered the eerie silence in an instant.

"What's going on?!"

"High-energy reaction reported from the special laboratory! Spiritual pressure is rising!"

"Damn it! It's the director's Sleep Project test subject! Who's on duty today?! Quick! Cut off the spiritual energy supply!!"

The Technology Development Bureau, already overwhelmed by the anomaly in Hueco Mundo, is now plunged into even greater chaos by this unexpected situation.

The researchers who remained rushed to the control panel in a panic, trying to contain the out-of-control force.

But it was all too late.

Snap!

The special glass, which was strong enough to withstand the spiritual pressure of a captain, was covered with spiderweb-like cracks the moment Sleep No. 8 opened his eyes.

What kind of eyes were those?

There were no whites in their eyes, no pupils, only two bottomless black abysses.

It was a chaotic mixture of the Shinigami's spiritual pressure and the Hollow's fury, catalyzed by Aizen's crystal.

boom-!!!

A huge explosion resounded underground.

The culture chamber shattered completely, with glass shards flying everywhere!

Nichika had already retreated into the shadows before the alarm sounded.

She gently drew her Zanpakuto from her waist, her eyes gleaming with azure light: "Show your might, Bishamon."

As she chanted, her Zanpakuto began to change.

Her hilt transformed into an octagonal piece of plain bronze, with a layer of pale purple-gold aura surging along the blade. Although the shape of the blade remained unchanged, it was impossible to see the blade clearly, as if looking at flowers through a fog.

Then, she placed her hand on the blade and spoke again: "Fu Jitian."

Upon hearing this, a heavy, purplish-gold spiritual pressure emanated from the sword, quickly covering her entire body.

In the blink of an eye, Nika's figure completely disappeared from the laboratory.

"Phew... I hope I don't get caught..."

She pressed herself tightly against the corner of the wall, her heart pounding wildly.

This is the Zanpakuto ability she has developed so far, capable of achieving near-perfect concealment of her aura.

Unless it's a powerful Shinigami like Aizen, no one would notice anything unusual.

The smoke and dust cleared.

When Nika saw the small figure hovering in mid-air, its body covered in broken tubes, she couldn't help but swallow nervously.

Several researchers who had just rushed in witnessed this scene, but before they could even speak...

roar-!!!

Sleepy No. 8 suddenly opened its mouth and let out a violent roar.

Dark red spiritual pressure ripples then swept across the entire laboratory.

not good!

Seeing the anomaly three seconds later through her future vision, Nika reacted quickly, ducking to avoid the impact of the ripples.

But others weren't so lucky.

"Ah! Damn it, it's the pollution of the void!"

"What is this?! Help!!"

The researchers were swept by this spiritual pressure wave, and their bodies began to undergo strange changes.

White bone masks forcibly grew from their faces, instantly swallowing their consciousness.

To blur or obscure.

The crystal that Aizen gave to Nika was actually a catalyst to stimulate the Hollowfication factor in No. 8's body.

It is spreading the ethereal pollution throughout the entire space through the medium of Sleep No. 8.

"Please all leave."

A flat, emotionless command came from the entrance of the passage.

The black skirt of the Shinigami uniform swayed slightly as she moved quickly, and a woman's figure appeared at the laboratory door.

"This spiritual pressure composition... is Hollow." She analyzed the situation of Sleeping Number 8 in front of her with the calmness of a machine.

She is none other than Mayuri Kurotsuchi, the vice-captain of the 12th Division.

Sleep No. 7 · Nirvana Dream.

She was supposed to be in the Technology Development Bureau's maintenance room, monitoring the anomalies in Hueco Mundo according to Mayuri Kurotsuchi's instructions.

But a few seconds earlier, her neural connections sensed an anomaly in the spiritual pressure fluctuations belonging to her younger sister, Sleep No. 8, inside the laboratory.

When she saw Sleep No. 8, suspended in the air, exuding an aura of emptiness, wreaking havoc.

She pressed one hand against the wrist of one arm, making a clicking sound: an unauthorized foreign object intrusion had been detected, and the structural stability of No. 8 had fallen below the warning threshold.

'

Once in combat mode.

Yinmeng's figure vanished from the spot in an instant.

The next second, she was already directly above Sleep No. 8.

"Target locked, begin elimination."

She compressed all her spiritual pressure into her right foot and unleashed a powerful downward slash, colliding with the berserk Sleep No. 8.

boom-!!

Countless researchers suffered as a result, forced to flee in panic to avoid being caught in the aftermath of the battle.

The entire underground laboratory was in complete chaos.

And this was the opportunity that Rixiang had been waiting for.

While Nie Yinmeng was locked in combat with the rampaging Mianba, and everyone's attention was drawn to her,

Nika dodged the aftershocks of the repeated bombardments and quietly slipped out of the laboratory.

However, her goal was not to escape.

Instead, it's located deeper within this laboratory, in a private archive room of the director that ordinary researchers are completely unaware of.

"It's all unavoidable... Don't blame me, it's all for a better world..."

L

As Nika recalled the map Aizen had given her, she raced forward through the intricate and complex path.

Finally, she arrived at a black metal door.

"This is... the final challenge."

Rika took a deep breath, pulled out a seemingly ordinary piece of white paper from her pocket, and stuck it on the demon mask's forehead.

Buzz—

The white paper instantly burned to ashes, transforming into a complex ghostly magic spell that burrowed into the ghost mask.

That was a forged pass created by Aizen when he secretly analyzed Mayuri's spiritual pressure wavelength during their collaboration.

Click click click...

The heavy metal doors slowly opened to both sides.

Behind the door was a small space.

There were no mountains of documents, nor the expected bizarre specimens.

The bookshelves on both sides didn't have many classic books, but each one seemed to exude a dangerous aura.

In the very center of the room, there is a transparent light dome suspended in mid-air, and inside the dome floats an ancient scroll that is sealed layer by layer.

That's what Aizen-sensei wanted.

Rixiang quickly stepped forward, not daring to delay for even the slightest moment.

She reached out and carefully touched the light shield, only to find that she couldn't move it even an inch.

...Indeed, it's a special protection mechanism.

She wasn't surprised; she simply held the purple-gold Zanpakuto, Bishamon, and spoke again:

'

"A treasure chest in the heavens."

A heavy pressure surged up again.

The aura that had enveloped Nisaka disappeared, transforming into a golden ball of light that eventually coalesced into a small treasure box pagoda in her palm.

As the tower rotates, the light shield begins to slowly distort and become illusory.

Taking advantage of the opportunity, Nika quickly reached out and grabbed the reel.

The moment your fingers touch the reel, a cool sensation spreads throughout your body.

"Got it..."

'

She didn't open it to look, nor did she have time to.

However, she still caught a glimpse of a line of small characters written in ancient script at the seal of the scroll.

Although it was only a glance, those two words seemed to possess some kind of magic, deeply engraved in her mind.

[Wang Yin]

"I'm sorry, Captain Negi... I'm sorry, everyone in the Technical Bureau."

Nika quickly stuffed the scroll into her bosom and hid it close to her body.

After removing the Treasure Chest Pagoda and activating the Aura Concealment once more, he turned and vanished into the shadows...

However, Nika was simply too focused on stealing the scroll...

Unbeknownst to them, a sophisticated camera was flashing red light in the corner of the laboratory, recording everything.

Wearing a strange hat, Mayuri Kurotsuchi stood in the monitoring room, digging his temples with his long, thin fingernails: "It wasn't for nothing that I sacrificed Number Eight as bait. I've finally let you show your true colors, Aizen."

So, this is your purpose? To find out the whereabouts of the royal seal?
