Death: Starting as the Guardian of Avici Hell

"Third-class spiritual particles cannot enter the cycle of reincarnation, which means that those captain-level powerhouses who died must fall into hell."

"And since the founding of Soul Society, it has been a million years. Even if only a very small part of it exists, it is still a considerable number."

"If we can seize the authority of Hell, we will gain a power that is no less than that of Soul Society."

"Of course, this is the best outcome."

"At present, we still know too little about hell, and we will have to wait for new research results to come out before we can make specific plans."

Naraku Sora was dumbfounded.

While he was still basking in the glory of his unconventional ways, Aizen had already begun planning to take the entire Hell with him.

"Sousuke, you seem to be going a bit too far."

Aizen ignored the person, simply activated the device, and released Hideyuki Iwahara, the former captain of the Third Division who had been retrieved from the Great Underground Prison of the Central District.

He casually lifted the seal.

Although this person is the captain, he has absolutely no sense of responsibility that a Grim Reaper captain should have.

At first, Aizen thought that he had been persecuted by nobles or framed, which was why he was imprisoned on the eighth floor of the Shinigami Prison.

It was later discovered that Yan Yuanxiu was secretly involved in human trafficking, using extreme methods to elevate the Yan Yuan family, originally a lower-ranking noble family, to the status of an upper-ranking noble family.

His crimes are too numerous to list.

Being imprisoned in the deepest hell is not an exaggeration.

If it weren't for the fact that if the Grim Reaper cultivated to the third level of spiritual power or above, the spiritual particles that constitute his body would be unable to enter the world cycle, thus affecting the balance between the three realms.

He should have been ordered to be executed or similar punishment when he was arrested.

Fortunately, he has now found a better place to belong.

Yan Yuanxiu realized that the binding seal on his body had been released. Just as he was about to beg for mercy, he was suddenly locked onto by an extremely terrifying spiritual pressure.

The immense pressure descended like a collapsing ocean, causing even the strongest bones to creak under the strain, and the flesh to cave in, offering no resistance whatsoever.

He could only watch helplessly as this evil brat named Aizen pressed a faintly glowing gem onto his forehead.

Make the best use of resources.

Before dying, let's make the most of our last bit of energy.

The moment the Hōgyoku touched his skin, Yan Yuanxiu felt an indescribable, terrifying power surge into his body from his forehead.

An unprecedentedly powerful feeling was constantly erupting within me.

It's as if they're trying to mold it into the most powerful Grim Reaper in the world.

This feeling is so wonderful that it makes people immerse themselves in it and unable to extricate themselves.

However, it was not long before her own endurance reached its limit, and what was originally enjoyable turned into painful torment.

Yan Yuanxiu opened his mouth, as if he wanted to let out a wail to vent his unbearable pain, but no sound came out.

Thick, white chitinous liquid gushed from the eyes, ears, mouth, and nose, making a gurgling sound that was quite eerie.

Under the influence of spiritual pressure, the liquid rapidly solidified, gradually forming a hard bone layer.

It covers the entire face and half of the body from top to bottom.

This time, Hideyuki Iwahara was finally able to speak.

However, it has deviated from human nature and has instead become a beastly roar composed of multiple mixed sounds.

The trembling figure, mixed with surging spiritual pressure, spread in all directions, transforming into visible sound waves that slammed heavily into the pre-prepared demonic barrier.

Aizen calmly watched the scene before him, recording all the changes in Yan Yuanxiu, while continuously analyzing the level of his spiritual pressure.

A large amount of data flowed smoothly from my pen without any hesitation.

As Yan Yuanxiu gradually approached the level of a second-class spirit, Aizen's mood became noticeably more cheerful.

Although the success rate of the blurring experiment is still not very high, based on the results of multiple experiments, we can now try to optimize some details.

If the Hogyoku can be completely perfected, the success rate will likely be a very satisfactory number.

That's right, the Hogyoku is a semi-finished product.

After a period of research, Aizen finally realized this.

Because there was no prior experience, his discovery came a little late.

Fortunately, the impact was not significant.

Based on the parameters obtained from the research, the Hōgyū can be improved.

Furthermore, someone suggested that Kisuke Urahara participate in the research on the Hogyoku.

Aizen initially didn't care about this, but in several subsequent collaborations, he suddenly discovered that Kisuke Urahara's talent in this area was in no way inferior to his own.

Moreover, even with an insufficient understanding of power, several valuable suggestions for improvement were still put forward.

It can only be said that tying Kisuke Urahara to someone's side was definitely one of the most correct decisions someone ever made.

When Aizen realized that Yan Yuanxiu's consciousness had completely spiraled out of control and was about to commit suicide, a sharp arc of electricity seemed to flash across his eyes.

The terrifying spiritual pressure solidified, crushing the solid outer layer of bone.

Next comes the skin, flesh, nerves, and bones.

One second, it was a complete person; the next second, it shattered into tiny spiritual particles, drifting in the air.

Seeing this, Naraku Sora, who had been guarding the instrument, pressed a button.

To accommodate someone, Aizen specially designed the device to be easy to operate, with only two buttons from top to bottom: one to start and one to stop.

Even if Kylian were to come, he could have completed the operation.

It's impossible for it to make a mistake.

A strange fluctuation unfolded, and the Hogyoku placed on the instrument emitted a dazzling light, like a lighthouse, instantly covering the surroundings and enveloping all the spiritual particles left behind after Yan Yuanxiu's shattering.

"During this period, I specifically studied the differences between Hellfire Rinnegan and Soul Society Spirit Particles, and discovered that they are related."

Aizen explained calmly.

"Based on this connection, and combined with the power of the Impure World Reincarnation technique, it is possible to convert third-class spirit particles, forcibly stripping away the spirit particles belonging to Hell, and causing the dead who originally fell into Hell to be returned to the embrace of Soul Society."

"Alternatively, one can directly activate the Impure World Reincarnation technique. All that is needed is a prosthetic body to revive the dead."

"This is the first step in seizing control of Hell."

The moment the words fell, a rumbling sound rose from the sky.

The interplay of black and red resembled congealed blood, and thick clouds shrouded the entire sky, as if the end of the world had arrived.

An ancient door slowly appeared, with skulls on both sides pulling it open.

A massive black vortex appeared, with electric arcs twisting wildly within it, and an immense suction force erupting from it.

However, after sucking for a long time, he didn't get anything at all.

It's as if something that should have belonged to it was intercepted halfway.

What happened?

Red light shone from the skull's eyes on the Gates of Hell, and an immense, indescribable pressure instantly descended upon the mountains and forests.

The ground cracked with a sound, and fissures like those in an abyss appeared one after another.

Aizen stared intently at the door in the sky, trying to capture it with his spiritual pressure.

Just as we guessed.

Yan Yuanxiu was a heinous criminal with a spiritual power level of three or higher, so when he died, he would summon the gates of hell.

However, he had already purified its spiritual particles ahead of time, causing what should have belonged to Hell to return directly to the cycle of Soul Society.

This also prevented the Gates of Hell from capturing Hideyuki Iwahara's spirit particles.

After a fruitless search, the terrifying noise slowly dissipated, and the Gates of Hell shattered like a bubble, disappearing completely from the sky.

"Success."

Aizen breathed a sigh of relief. "Next, we need to continue our research in the current direction and then influence Hell in reverse, taking away all the captain-level Shinigami who have fallen into it."

Upon hearing this, Naraku thought for a few seconds:

"Does what we're doing amount to defying hell?"

Aizen: "?"

……

……

After they stormed Hell together with Aizen, nothing strange seemed to happen, and Soul Society remained unchanged.

The air was quiet and peaceful, just like always.

A few months later, Naraku received some unexpected good news.

Gin Ichimaru and Byakuya Kuchiki both graduated early.

Moreover, they submitted their application to join the team to the Shin-O Prison immediately.

Looking at the two people in front of him who were only slightly shorter than him, Naraku scratched his head.

Gin Ichimaru's choice to go to the Central Prison is fine, but why did Byakuya Kuchiki have to get involved?

You're a member of the Sixth Division, born and dying a member of the Sixth Division.

If that old bastard Kuchiki Ginryo finds out he's kidnapped his precious grandson, he'll definitely come to Zhenyang Prison with a knife and fight to the death.

However, an old man simply doesn't understand what bonds are.

If Kuchiki Byakuya stays here, with the lashing of Ichimaru Gin and others, he will only become stronger and more ferocious.

Naraku Sora happily took the two into his ranks, adding two more powerful warriors to the Shinigami Prison.

The future is expected.

After casually tossing the two men to Komamura Sajin and the others, Naraku returned to the steward's office.

As soon as I entered, I saw Kisuke Urahara working at his desk, with a small mountain of documents piled up on the table next to him.
