I'm in Bleach, starting with Unlimited Blade Works.

"This world underwent a tremendous change a million years ago when the Soul King created the three realms of the Human World, Hueco Mundo, and Soul Society, thus dividing life and death."

"But since then, this world has fallen into the same situation as the previous world."

"The nobles wield power, standing high above, while ordinary people grovel on the ground, barely clinging to life..."

"The history of Soul Society over millions of years has been monotonous, never changing in the slightest..."

"In my view, this is not fundamentally different from the chaotic world before."

"Because they are all at a standstill, with no sign of progress whatsoever."

"Whether it's me or you, we are all people who pursue evolution and transcendence."

"The current state of Soul Society is incompatible with ours."

"We are the wind that brings forward the stagnant world, turning the world's windmills forward."

"On the road to changing the world, we will either change the world or be crushed by it."

"Captain Aizen truly lives up to his reputation as the one who created the strongest Zanpakuto of the Genjutsu type. His eloquence and control over other people's emotions are far beyond my reach."

With a casual wave of his hand, Erin caused the black bandages on Aizen's body to transform into Kido runes, which eventually shrank into Aizen's heart, leaving only a small black dot.

"boom!"

With the seal broken, Aizen opened his arms, and immense spiritual pressure emanated from his body, creating waves of spiritual energy within Erin's Reality Marble.

"Oh?"

Erin was slightly surprised to sense the intensity of Aizen's spiritual pressure.

He never expected that Aizen, whom he had sealed away for over twenty years, would have such a powerful spiritual pressure that it was much stronger than it had been twenty years ago.

Aizen's spiritual pressure has now reached the limit of a captain who has been in power for a hundred years.

It was only a hair's breadth away from the Shinigami's limit of spiritual pressure.

Aizen stretched out his hand towards Erin, and the next moment, a crystal emitting blue light rose from Erin's arms, eventually transforming into a streak of light and flying towards Aizen.

"boom!"

With the help of the Hogyoku, Aizen's spiritual pressure finally broke through its shackles and reached the limit of a Shinigami.

"Clap clap clap clap..."

"Beautiful, Captain Aizen."

Erin clapped his hands in admiration, "I never imagined that Captain Aizen and the Hogyoku had such a close connection. Moreover, the power of the Hogyoku could actually affect Captain Aizen within my Reality Marble in Soul Society..."

"It seems that I underestimated both Captain Aizen and the Hogyoku."

Seeing Aizen's breakthrough, Erin knew perfectly well that even if he hadn't agreed to release Aizen Sousuke, one day in the future, under the influence of the Hogyoku's power, Aizen's spiritual pressure would break through the limits of a Shinigami, and he would naturally be able to break free of the seal on his own.

Of course, breaking free from the seal is one thing, but whether one can escape from the inherent barrier of Erin is another matter entirely.

However, if Aizen possesses the power to break free from the seal but chooses not to, he could still cause Erin significant trouble when Erin encounters an enemy that requires the use of a Reality Marble.

Furthermore, if Aizen had only intervened at the most crucial moment in Erin's battle with the enemy, Erin might have ended up at Aizen's hands.

"No, it's all thanks to Captain Erin always carrying the Hogyoku with him that I was able to draw power from it through his connection with this space."

Aizen Sousuke carefully put away the Hogyoku, withdrew his spiritual pressure into his body, and slowly descended in front of Erin.

Aizen wasn't wrong about what he said.

The Reality Marble Infinite Blade Works is the space created by Erin's Zanpakuto.

The Zanpakuto within this space can all communicate with Erin through the connection between Erin and his Zanpakuto.

Aizen was imprisoned in Erin's soul space, and in some ways, he was no different from the "spirit" of his Zanpakuto.

After all, the earliest Zanpakuto were forged using the souls of Hollows or Shinigami.

Erin's clone always carried the Hogyoku with him, which gave Aizen an opening.

"Very good. Captain Aizen's breakthrough has further increased my confidence in him."

"Next, I will show Captain Aizen what has happened during this time, so that he won't become out of touch with the world."

After saying that, Erin drew his Zanpakuto from his waist under Aizen Sousuke's questioning gaze.

"Shatter, you illusion, you mirage!"

For a fleeting moment, a glimmer of light flashed in Aizen's pupils.

Then, many images appeared in Aizen's eyes.

Entering Hueco Mundo, she commands the power of the Espada, the new 30th Espada, Hauribel…

In Soul Society, Hollows were accidentally born from experiments involving the Hollowfication of Shinigami, possessing the fighting instincts of Shinigami...

He went to the Shinigami Academy to teach the students the Four Shinigami Techniques and showcased his Zanpakuto, Kyoka Suigetsu...

As the proctor for the sixth-year students of the Shinigami Academy, a student's selfish actions led to the addition of a new rule to the Shinigami Academy's graduation exam...

Over the years, everything Erin did under the identity of Aizen Sousuke has come to light in Aizen Sousuke's eyes.

Everything Erin had done over the past twenty years was completely transmitted to Aizen in just a few dozen breaths.

Erin believed that even if Aizen Ko hadn't done these things, Aizen Sousuke would still assume that he had done them after seeing them.

Aizen's understanding of people's hearts and human nature far surpasses that of Erin.

"Wonderful!"

"It seems I was right about you, Captain Erin."

"You and I are the same kind of people."

“We are not like Kisuke Urahara, who is complacent and blindly foolish.”

"If he is willing to serve such a Spirit King, then let us send the Spirit King off on his final journey!"

Having witnessed Erin's actions over the years, especially the Hollow he had bred that possessed the fighting instincts of a Shinigami, Aizen was truly amazed.

This Hollow was nurtured from the spiritual particles of a large number of Shinigami who had been corrupted into Hollows, and it was born with the potential to possess the powers of both Shinigami and Hollows.

It can be said that this Hollow's potential is far greater than that of the Hollows Aizen saw in Hueco Mundo.

If he were to continue nurturing this Hollow, it would undoubtedly be of great help to his research on how to break through the limits of a Shinigami.

"No, Captain Aizen, we are not on the same path."

When Aizen still insisted that he and Aizen were on the same side, Erin quickly raised his hand to signal him to stop.

The reason he did so many things was to ensure the birth of the protagonist, Ichigo Kurosaki, based on the memories in his mind.

This is Erin's safety net for the world.

Unexpectedly, Aizen took everything Erin did as Erin's thoughts and ideas, and viewed them almost exactly the same as his own.

Erin tucked the Kyoka Suigetsu back into its scabbard at his waist and threw Aizen's Kyoka Suigetsu, scabbard and all, to him.

"Aizen, this is the first time I've let you go, and it's also the last time I'll let you go."

After Aizen put Kyoka Suigetsu back into his waistband, Erin continued speaking to Aizen.

Chapter 243 Yoruichi's Worries

"You know perfectly well what you did to be imprisoned by me."

"If I discover that you have any intentions toward those around me again, then I'm sorry, Aizen..."

"I will personally kill you, so that your soul will not even have the chance to go to hell!"

Aizen's smile flickered slightly.

In this world, many people know that hell exists.

However, very few people truly understand the nature of hell.

Unfortunately, Aizen Sousuke was one of them.

After all, the people and events that happen in Soul Society are recorded in the "Great Spiritual Library," and Aizen, who possesses the Kyoka Suigetsu, is a frequent visitor to the "Great Spiritual Library."

Many of the secrets of Soul Society were learned by Aizen in the "Great Spirit Book Corridor".

This includes the "King's Key," which is necessary to access the Spirit King's Palace, and the method for creating the "King's Key."

Hell is a world that was born at the same time as this world. Unfortunately, the "god" who created the world of death left after creating it halfway through, for some unknown reason, leaving the world of death as a "half-finished" world.

At that time, the world was in chaos, and there was no boundary between life and death.

After some time, the world evolved, and one soul fell into the void, beginning to grow by devouring other souls.

Unfortunately, in that world, neither the living nor the dead possessed any special power to stop this void from devouring more souls.

If this continues, this void will devour all the souls in this world, and the world will become a giant void.

Perhaps it was the world's instinctive awakening that led to the world giving birth to its own "god"—the Spirit King—after this void had almost devoured half of the soul.

The Soul King, born from the will of the world, used the power of annihilation to destroy the Hollows, and then used his omnipotent power to create the three worlds of the human world, Hueco Mundo, and Soul Society, thus dividing life and death.

At that time, everyone thought that the world had been fully formed. The five noble ancestors who had gained power by following the Spirit King ultimately betrayed him.

However, after sealing the Spirit King and using it as a wedge to stabilize the world, everyone discovered that this world actually had another side—Hell.

Hell is the other side of this world. In the beginning, Hell was very small and belonged to a very insignificant world.

However, Hell can grow by devouring souls.

However, Hell can only devour the souls of evil people, so Hell grows very slowly.

But no matter how slow the growth is, when the timeline is stretched out, the growth of hell never stops.

Over the past million years, Hell has grown to half the size of Soul Society.

Furthermore, in order to grow faster, the will of hell exerted some influence on the Soul Society.

The most famous example is the "team funeral ceremony" for captains and above.

The so-called "team funeral ceremony" is because the spiritual pressure of powerful individuals at the captain level or above is too strong, and their bodies do not transform into spiritual particles to return to the world after death.

So, after a series of rituals, the Grim Reapers cremated the bodies of the deceased captain-level powerhouses, allowing their corpses to return as spiritual particles.

However, the Grim Reapers were unaware that their so-called "team funeral ceremony" was not about returning the spiritual energy of a captain-level powerhouse to the world, but rather about sending the spiritual pressure of a captain-level powerhouse to Hell through the ritual.
