Death: Starting as the Guardian of Avici Hell

With his current level of scientific research, he is not yet capable of reaching that level.

Moreover, resurrection was not part of his research project, so it's normal that he doesn't know much about it.

After briefly explaining the principles involved in resurrection to someone, Aizen seemed to suddenly realize something, and frowned, saying:

"You don't mean to let me or Kisuke Urahara know the method of resurrection so that we can go around courting death without any worries, do you?"

"If this is your idea, then I advise you to give up as soon as possible."

"The essence of resurrection lies in the soul. Perhaps only a Spirit King from millions of years ago could achieve it."

"Moreover, the forced resurrection by gathering spiritual particles also has limitations. Once the soul is erased, it will completely disappear from this world."

Hearing Aizen's prejudice, Naraku retorted in a powerful voice:

"Do you really think I'm such a reckless person?"

"Correct."

Nai Luokong: "..."

You could at least have hesitated for a moment; your instant reply made me lose face.

Ignoring Aizen's slander, Naraku Sora stretched out his right hand, snapped his fingers, and grinned:

"As everyone knows, my wisdom is astonishing."

“Unlike that guy who mocks others the moment we meet, I, Kong, have come with the latest research results.”

"Not long ago, I had a sudden inspiration and developed a method of resurrection that could bring the dead back to life."

Aizen looked at the talkative guy with a strange expression, and even suspected that Naraku Sora had been beaten too much by Yamamoto, causing him to have mental problems.

Seemingly sensing Aizen's presumptuous idea, Naraku Sora didn't bother to argue with him.

Seeing is better than hearing.

Instead of wasting so much breath, let's just have a real demonstration.

This is a perfect opportunity to give Aizen a little shock with a forbidden technique.

Naraku Sora pulled out a list he had prepared in advance and then selected a less important test subject in the laboratory.

He was previously imprisoned in the Shinigami Prison, but was later given to Aizen as material for his experiments.

It doesn't have much value now.

Aizen took the list and read it carefully.

It was filled with complex demonic incantations, and even with his level of demonic cultivation, he found it difficult to understand.

Could it be that this guy has actually developed a forbidden technique for resurrection?

Aizen raised his eyes and just in time to see someone release his material from the container, then rub his hands together on his head and chin, rendering it useless.

Then, another artificial skeleton was moved out from another laboratory.

This is the tool used by the Grim Reaper when he walks through the human world. It can be used as a container to protect the Grim Reaper. Different manufacturing methods will give the artificial body different effects.

The most basic thing is to isolate spiritual pressure and restore spiritual power.

"Sousuke, watch carefully and learn well."

Naraku Sora stood before the corpse, hands clasped together, and said earnestly:

"Now comes the moment to witness a miracle."

"The Impure World Reincarnation Technique!"

The moment the words fell, Aizen's eyes widened in surprise as he saw a Kido barrier centered on a Gikai unfold on the ground.

With a burst of intense white light, the artificial body that contained no death slowly stood upright, as if it had come to life, constantly twisting and struggling.

Countless grayish-white dust particles were stuck to the artificial body like paper.

Then, within the range of spiritual pressure perception, the originally dissipated spiritual particles were forcibly gathered into the artificial body by some kind of force.

Something incredible happened.

The material that had already died was resurrected on a prosthetic body, and even unleashed a spiritual pressure comparable to that of its living self.

"What... happened to me?!"

The Grim Reaper looked completely bewildered, having no idea what had happened.

Even Aizen frowned, a strong sense of confusion flashing in his eyes.

To be honest, I didn't understand what just happened at all.

This guy simply made a few hand gestures, then set up a fake body, and then resurrected the dead.

If this was indeed researched by Naraku Sora, then this wisdom can truly be described as astonishing.

Even he would feel inferior to him.

"How did you do that?"

Naraku Sora grinned, a smug look on his face.

"Of course, it was a forbidden technique of the ghost path that he developed with his extraordinary wisdom."

"Through an ultimate understanding of the return path, a spiritual particle cycle is simulated and transformed, and then..."

"Um, I forgot the rest."

"In short, this is the advanced technology I have developed."

"If you want to learn, I can teach you."

Aizen couldn't help but roll his eyes.

You figured it out yourself, but you can't even explain the underlying principles, right?

Although his words were incoherent, he had a vague guess.

It's mostly related to Naraku Sora's special ability; his mastery of Hollowfication probably came from this.

With that in mind, he stopped worrying about the origins of the forbidden ghost arts and began to think about the benefits and changes that "resurrection" could bring.

"Based on my observation just now, the basic operating principle is to forcibly bind the spiritual particles that are about to enter the cycle into the artificial body, and then, through arrangement, create a body that is exactly the same as the original."

"It all comes down to the soul."

"From this perspective, it seems that the Gikai was born to be prepared for this forbidden Kido technique."

Naraku snapped his fingers: "As expected of Sousuke, whose wisdom is second only to mine, he guessed the correct answer in just a few words."

Aizen: "..."

Why am I not happy at all even though I received praise?

If the previous guesses are true, then the value of this guy needs to be reassessed.

Or rather, this is the fundamental reason why Hyosube Ichibei and the King of Souls are paying attention to him.

Considering the various unusual things someone has done in the past: their exaggerated and outrageous talent for cultivation, their perfect intangible form, their powerful Zanpakuto, and their astonishing wisdom that is so simple it's all made of muscles...

Aizen suddenly calmed down.

It seems that nothing is surprising when it comes to this strange guy.

"If it's just about resurrecting someone who has just died, then this forbidden technique isn't very valuable. At most, it's comparable to forbidden techniques like time stop and spatial teleportation."

"After all, whether it's a Shinigami or a Hollow, once they die, their souls will merge into the cycle. This is the underlying logic of the world."

"But there is one exception."

Aizen adjusted his glasses, a strange light flashing across the lenses.

“A spirit particle of third-class spiritual power cannot return to the cycle and will continue to drift in the Soul Society until the Soul Burial Ritual is held and it falls into hell completely.”

"So here's the question: can the dead, who have fallen into hell, be resurrected by this forbidden demonic art?"

Upon hearing this, Naraku's eyes lit up.

"Since it won't have any impact anyway, we might as well give it a try first."

Aizen pondered for a few seconds.

Considering that there are no death gods of level three or above dying at this stage, the soul burial ritual will not normally be held, so there is no major risk.

Therefore, he readily agreed.

The two hit it off immediately and pulled out the only precious material related to hell, Zomali Lulu, from the deepest part of the laboratory.

Just in case.

Zomary was covered in various binding spells, from number one to number ninety-nine, binding him completely, including Aizen's own sealing demonic arts.

Noticing that the person who had beaten him was right in front of him, Zomal immediately let out a whimper, trying to warn the person not to mess around, as his value was not what it used to be.

Naraku Sora ignored the guy's howls and began preparations for the second round of Impure World Reincarnation.

It was still a prosthetic body as a backup, and several restrictive Kido spells were also applied to prevent it from breaking free of control after resurrection.

Then, under Zomari's incomprehensible gaze, Naraku clasped his hands together:

"The Impure World Reincarnation Technique!"

A powerful gravitational force erupted, and the artificial remains on the ground emitted a dazzling white light.

To Zomali's horror, he discovered that his body was constantly colliding with the outer layer of binding seals, and within seconds, more than a dozen binding seals were shattered.

then.

As if it had been turned into sand, its body shattered completely, turning into countless tiny spiritual particles that broke free from the binding spell and rushed into the artificial body.

When Zomali regained consciousness, he was suddenly shocked.

The powerful suppressive force that had been acting on the soul inexplicably disappeared, replaced by a completely different power.

Following the direction of my senses, I found myself face to face with Naraku Sora.

Zomali frowned, completely bewildered as to what had happened.

But judging from the current situation, it seems to be a good thing.

He was freed from his hellish state and regained his freedom.
