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

Chapter 243 Collapse of Jade
Late at night, in the 12th Division's laboratory
Mayuri Kurotsuchi tapped his fingertip lightly, looking at the information on the screen.

"They really are willing to spend money..."

After a long while, Mayuri Kurotsuchi expressed his heartfelt feelings, which included a hint of admiration.

This was the "deposit" that Aizen Sousuke sent him after they finalized their collaboration—a research document about the Hogyoku.

Although it is only a partial result, the concepts and technical details it contains are enough to drive any scientist who seeks the mysteries of the soul crazy.

After all, Aizen used a lot of Shinigami, Hollows, and commoners from Rukongai as research materials in order to create the Hogyoku.

Although he didn't approve of this research method, the data was indeed quite valuable...

Aizen's purpose in giving him this information was not simple. On one hand, it was bait set for him by the other party, and on the other hand, it was Aizen explaining his own purpose.

He created the King's Key using the Hogyoku, and then... went to the Spirit King's Palace to personally pull down the being that resided high in the sky and was revered as the cornerstone of all things.

Just like that line in the original work, he will stand high in the sky.

Of course, the benefits of cooperating with Aizen are obvious, but the troubles are also numerous.

However, Mayuri Kurotsuchi had already made her decision.

After all, Soul Society simply doesn't provide the environment for his research. Unless he abandons his research, the consequences will be far more severe than just the death penalty.

On the contrary, Hueco Mundo is actually more suitable for his research...

"Yinmeng".

Thinking of this, Mayuri Kurotsuchi spoke without turning his head.

"Yes, Lord Mayuri."

Nie Yinmeng's figure appeared silently behind him, as calm as ever.

"Delete all the original data of the [Soul Materialization] project, as well as Plan Thirteen regarding the 'Property Soul' modification."

"In addition, we will organize all the technical data left behind by Kisuke Urahara and prepare for its transfer."

Mayuri Kurotsuchi gave the order: since they were preparing to escape, he would naturally take anything of value with him.

"All of them?"

A barely perceptible ripple flashed in Nie Yinmeng's eyes.

"All."

Mayuri Kurotsuchi offered no explanation, but simply issued an unquestionable order.

"learn."

Nie Yinmeng nodded without asking why.

As an artificial life form, the greatest significance of her birth is obedience.

……

In the days that followed, just as the original story had unfolded, the invasion of Ichigo Kurosaki and his companions turned the entire Seireitei upside down.

Alarms and the roar of battle filled the air, the captains of the Gotei 13 were overwhelmed with work, and the entire Seireitei was in complete chaos.

This chaos provided the perfect backdrop for Aizen's plans.

When the news of the assassination of Aizen Sousuke, the captain of the Fifth Division, arrived, Mayuri Kurotsuchi was in his laboratory debugging a sophisticated instrument.

He glanced at the emergency notification that popped up on the screen, and a mocking smile appeared on his lips.

Next, it's his turn to appear...

As agreed, he needed to assist the "deceased" Aizen in completing the most important part of the plan.

Before the execution of the verdict by the Central 46th Chamber, the Hogyoku, which had been hidden by Kisuke Urahara, was removed from Rukia Kuchiki's body.

The tool in his hand was a completely new creation, combining the technology left behind by Kisuke Urahara and his own research findings. ...

On the eve of the execution, the moonlight was as pale as frost.

The towering Palace of Repentance, reaching into the clouds, resembles a white sword piercing the sky in the night, and the surrounding air is filled with a sense of solemnity and oppression.

Two figures silently passed through the layers of ghostly barriers, as if they had merged into the shadows.

Aizen Sousuke, walking ahead, still maintained his gentle captain demeanor, but his pupils behind his glasses flowed with unfathomable calm and confidence.

Mayuri Kurotsuchi followed behind him, watching Aizen's actions with great interest.

Aizen's Zanpakuto, "Kyoka Suigetsu," possesses a completely hypnotic ability that is truly a bug-level power.

As they traveled, the guardians of death they encountered ignored them, as if they were merely two invisible wisps of air.

Inside the cell where Rukia Kuchiki was imprisoned, there was an eerie silence.

The girl huddled in the corner, looking extremely haggard from days of imprisonment and inner torment.

She heard news from the outside world that her companions in the human world had come to Soul Society to save her.

Because of her, her companions might very well die...

Why... is it like this...

Before Rukia could figure out what was happening, the demonic barrier around the cell suddenly opened.

Two figures then appeared; they were Aizen and Mayuri Kurotsuchi.

"what?!"

Rukia Kuchiki was startled, but before she could react to what was happening, Aizen had already made his move, pointing a finger at Rukia's forehead.

The spiritual energy seeped in gently and precisely, instantly plunging her into a deeper state of unconsciousness.

"Keep watch for me, Captain Nie."

As Aizen spoke, he took out a test tube from his pocket; it was a potion for separating the Hogyoku from the spirit.

"Tsk tsk~ They really know how to order people around~"

Mayuri Kurotsuchi shook his head and looked in another direction. If he wasn't mistaken, that spiritual pressure should belong to Byakuya Kuchiki.

……

the other side.

Kuchiki Byakuya was rushing over at all costs. He had received a secret report from his confidant that someone had used abnormal means to trigger the highest level barrier of the Palace of Penitence.

Fortunately, he lingered nearby to accompany Rukia on her final journey...

He pushed his Instant Step to its limit, and almost instantly upon receiving the news, he traversed a thousand meters and appeared outside the prison cell.

The scene inside the cell, however, left him stunned, and for the first time, a look of astonishment appeared on his perpetually icy face.

Aizen Sousuke, the captain of the Fifth Division who should have been "dead," was squatting on the ground, seemingly groping for something inside Rukia's body.

Meanwhile, Mayuri Kurotsuchi, the captain of the 12th Division, known for his madness and eccentricities, was watching him with great interest...

Why? Why didn't Aizen die? Why did Mayuri Kurotsuchi collude with him? What do they want to do to Rukia?!

Countless questions exploded in my mind, but were instantly replaced by overwhelming rage.

Whatever the reason, there is only one fact: someone is in front of him, trying to harm his only family member!
The next moment, Byakuya Kuchiki's figure disappeared from the spot. Driven by anger, he pushed the Shunpo technique, personally taught by Yoruichi Shunshin, beyond its limit.

Without any time interval, the silver blade flashed like lightning tearing through the night, carrying endless killing intent, and went straight for Aizen's neck!
However, faced with this fatal blow, Aizen didn't even turn around, because there was no longer any need for him to intervene.

The next moment, Mayuri Kurotsuchi appeared in front of Byakuya Kuchiki, pinching the blade of Byakuya's sword with two fingers...
