Chapter 128 The Disturbance in the Shadows

Chapter 128 The Disturbance in the Shadows

At the top of a skyscraper not far away.

Tosen gripped the hilt of his sword tightly, his spiritual pressure already in turmoil due to his emotions: "Lord Aizen... Experiment White has been completely destroyed. And the power that Shinigami displayed was far beyond normal limits!"

"Should we take action now to capture him? That person's soul is extraordinary; it must hold a secret that transcends realms!"

Aizen Sousuke stood at the edge of the rain curtain, his deep brown eyes fixed on Shiba Isshin, who was helping a flying bird up below, and the Quincy girl tending to her wounds.

He is thinking.

Number 78 was a little devil he accidentally acquired while secretly collecting wandering spirits in Rukongai.

The reason it was an accident was because one of his former subordinates was quite capable; he managed to trick the kid into coming to the lab right in front of the 46th Bureau of Investigation and Statistics.

It's hard to imagine... if I'm not careful, my plan might be exposed prematurely.

In gratitude for this guy's recklessness, Aizen has already fused his soul into his own experimental subject.

Why would the 46th Chamber go to such lengths to search for a kid of this age in the Tora Ward, and not just once or twice...? Aizen made many guesses.

Illegitimate children, theft, family scandals... anything is possible for these corrupt individuals.

Whatever the reason, Aizen felt that perhaps this No. 78, who refused to tell him his name, was the person Room 46 was looking for.

Therefore, when carrying out his own [Hogyoku] experiment, he always paid special attention to this kid, replicating his latest experimental results on him.

But the more he experimented, the more confused Aizen became.

This kid's body is like an abyss; no matter what material you use on him, you won't make a ripple.

This fueled his growing interest, and he resorted to increasingly extreme methods.

He could certainly sense Number Seventy-Eight's hatred; after all, he was a very perceptive person. But so what?

This little devil is destined to be just a piece of the puzzle in finding the ultimate answer on his own.

Until one day, number seventy-eight disappeared.

There was absolutely no warning.

Aizen's laboratory was extremely well-hidden and was sealed with a high-level Kido seal. He believed it was impossible for anyone to sneak in silently and rescue this mysterious brat.

But it happened anyway, and no trace of number 78 could be found.

To prevent such an absurd situation from happening, Aizen even left a fragment of spiritual pressure deep within his soul as a backup plan to sense his location.

But now, even that fragment can't be found.

Even though such a bizarre event occurred in Soul Society, it makes one wonder if it's a ghost story.

But as time went by, decades passed in the blink of an eye, and Aizen gradually let go of the matter.

Perhaps he had used too much material in one of his experiments... He comforted himself by thinking of it as a failed experiment.

But today, when he saw the bird again, his body involuntarily twitched.

Those were fragments of his spiritual pressure, detached from Asuka's soul, rushing towards him.

A flood of memories rushed into his mind, and even though Aizen was a man of great experience and ambition, he couldn't help but freeze in place.

"Another world? Another world with a complete life form, yet completely detached from the spirit particle cycle??"

"How did Number Seventy-Eight manage to do that? Why did he open the door to another world? Is it possible to go to that world again? What are the conditions?"

Countless questions kept bombarding Aizen's mind, but he could not find the answers.

Because even birds don't know.

Moreover, this memory only extends to the time when Asuka was fighting on the Mugen Train.

Aizen knew nothing about his later experiences, including how he opened the gate.

Compared to this matter, things like Xu Bai seem less important now.

"Captain Aizen? Are you alright?"

Silver-haired Gin Ichimaru approached with a smile, noticing that Aizen was unusually quiet today, seemingly lost in thought.

Is it an opportunity?

He thought about it for a while, and finally shook his head at himself.

Aizen realized he had lost his composure, let out a soft sigh, and regained his composure, even sporting a meaningful smile.

"No need, it's not the right time yet."

Aizen gently pushed up his glasses, a cold glint flashing across the lenses: "Look over there..."

"That is..." Tosen Kaname tilted his head slightly, his expression turning serious.

In the center of the battlefield, Shiba Isshin was struggling to carry the unconscious Asuka on his back.

"Hey, little girl, can you still walk?" Ichishin turned back to look at the girl whose shoulder was bleeding, his voice filled with worry. "By the way, what kind of power do you have? It looks really amazing!"

The girl paused, seemingly struggling with her thoughts for a long time before finally speaking: "My name is Kurosaki Masaki, and I'm a Quincy!"

The Quincy are the mortal enemies of the Shinigami, and there exists an irreconcilable feud between them.

Masaki hesitated for a long time before giving this answer, but in the end she chose to be honest.

Upon hearing this answer, Shiba Isshin was clearly stunned, which made Kurosaki Masaki a little nervous.

"Really? So you're a Quincy. This is the first time I've ever met one. I feel like I've hit the jackpot!"

? Didn't you mean...

"My name is Shiba Isshin! Anyway, Quincy girl, thank you so much for today!" Isshin bowed gratefully and quickly added, "Shouldn't you see a doctor? This injury..."

"I'm fine, Mr. Shiba... Compared to me, your companion seems to be dying..."

"

Isshin also noticed this.

Asuka's current situation is extremely strange; his spiritual pressure is rapidly declining.

What he just displayed... was practically captain-level spiritual power, but now he looks as weak as...

who!

Just as he was about to use Shunpo to take Asuka away, two figures wearing black cloaks suddenly blocked his way.

"Oh dear, Shiba, if you fight in this state, you'll get wrinkles."

A voice, both extremely frivolous and yet exuding an unparalleled sense of composure, rang out in the rain.

The cloak was lifted, revealing a green and white striped hat.

Kisuke Urahara lowered the brim of his hat, obscuring most of his face, and the folding fan in his hand covered the corner of his mouth, leaving only his sharp eyes flashing in the shadows.

"Who are you?" Shiba Ichishin didn't recognize the person in front of him and looked at him warily, but his wariness vanished instantly when he saw another face.

"Night... Night One, the boss!!"

As a member of the Shiba family, he naturally recognized this famous commander of the four noble families.

"Yo! You brat from the Shiba family!"

Another cloak was also lifted, revealing a head of signature long purple hair and golden vertical pupils.

Yoruichi Shihouin crossed her arms, looking down at him with a smug grin, revealing her fangs, her tone as authoritative as ever: "Long time no see. You're still as reckless as ever!"

"I didn't expect it to be Kisuke Urahara and Yoruichi Shihōin... So they're in Karakura Town... It seems there are more spectators tonight than I thought."

Aizen turned around, his cloak billowing in the wind and rain: "It's not the right time yet. It's better not to expose ourselves to them."

"Is it okay? As long as we act together, maybe..."

"No need, Gin." Aizen interrupted him with a smile, his gaze deep. "I want to see what changes will occur in Number 78 under Urahara Kisuke's observation."

"Although we deviated from our original goal, we also surpassed it..."

'

"Let's retreat. Tonight's experiment... has yielded data more valuable than we expected."

Three figures, concealed by cloaks of spiritual pressure, vanished silently into the darkness, as if they had never existed.
