Death: Starting as the Guardian of Avici Hell

Compared to the tedious and monotonous daily work, Aizen prefers the feeling of exploring the unknown.

He originally thought it would take him a long time to get to this point.

But ever since they reached a cooperation agreement with someone, the research progress has been advancing at breakneck speed.

Materials that used to require a lot of time and effort to find and capture can now be obtained in a single trip.

For example, Captain-level Shinigami, Arrancars who have broken through their own soul limits, Gillian who is about to evolve into Adjuchas, and Zanpakuto that can copy the power of other Zanpakuto...

Speaking of which, Naraku Sora had mentioned before that once things calmed down, he would borrow Muramasa from Kuchiki Hibiki River for a while.

Aizen was also very interested in that being that could materialize or even turn the spirits of other Zanpakuto.

If he weren't worried about revealing his identity, he would even have considered seeing what the materialized version of Mirror Flower Water Moon would look like.

I've heard that some biological Zanpakuto can be modified, but I wonder if the materialized Zanpakuto spirits possess this capability.

In fact, with the moves that guy taught him, the value of "Illusory Flower in a Water" seems to have diminished considerably.

As Aizen thought about it, he quickly calculated the relevant values ​​in his mind.

Yes, there shouldn't be any omissions.

Just as he was about to finish the final result, the swishing sound of writing suddenly stopped.

Aizen's smile froze, and he suddenly looked up at the window.

An overwhelming spiritual pressure, like the collapse of the heavens or the eruption of a dormant volcano, suddenly appeared within the Seireitei, sweeping outwards in all directions with overwhelming force, suffocating all who beheld it.

At first, Aizen didn't pay much attention to it.

Even if a traveler or a Hollow breaks into the Seireitei, other captains will take care of it.

Even if all else fails, there's still Captain-Commander Yamamoto.

There's no need for him to worry about it at all.

But just as that spiritual pressure swept past, he sensed a peculiar aura.

He was extremely familiar with this.

Failed!

How could that guy's aura be mixed with this overwhelming spiritual pressure?

Could it be that this is the trouble he caused?

Aizen narrowed his eyes and released his spiritual pressure to sense her.

No one in the barracks can detect his spiritual pressure now, so they can act with complete peace of mind.

After confirming it several times.

Aizen opened his eyes, a conflicted look on his face.

Although he didn't know who the owner of that unfamiliar spiritual pressure was, judging from its undisguised brutality and malice, the situation on the scene might be even worse than he had anticipated.

A wisp of white lightning erupted from his palm, instantly destroying the data he had painstakingly calculated.

The next moment, the Kido spiritual pressure covered his body, and Aizen's figure flashed and disappeared from the steward's room.

……

……

Naraku Sora stared in shock at the drastically changed person before him.

No, to be precise, it can no longer be called a human being.

The severed head of Tsunayo Taketaka, covered in black mud, was shakily repositioned at the broken end.

Looking at the scene before him, Naraku was a little numb.

You said if you place it neatly, it's fine, but even if it's a little crooked, it's acceptable.

How the hell could you stick the top of your head into your throat?!

Although the process was wrong, the result was good.

Tsuna opened his eyes, and the multiple pupils looked quite oppressive. Even a casual glance from him gave one the illusion of a heart palpitation.

The darkness is boiling.

The dark shadows stirred up ripples, and amidst the sounds of countless joints rubbing together, eyes slowly opened.

The immense spiritual pressure was receding.

It has switched from the original full power mode to energy saving mode.

This is a fundamental shift, moving from unlimited coverage to focusing on one person, and then moving into a deeper realm.

It was like a transformation of some giant of light.

At this moment, accompanied by frantic twisting and turning, spiritual pressure surged, frantically draining the endless power from this body, and a brand new heart began to beat.

Sharp horns, resembling a bull's head, sprouted from the black mud, their shadows spreading and intertwining, then clinging to the deformed body, forming a massive, half-human, half-beast shape.

Twelve arms emerged from behind, cradling the moon like stars around the chest—

A bizarre bone face.

Then, it was placed on the upside-down head.

The deformed creature stood upright, lowered its head, and its two pupils on the bull's head quickly roamed before finally locking onto Naraku Sora.

A jet-black spiritual pressure surged up from its body.

The silent hissing spread out from Yuqian Hall.

Driven by instinct, Naraku raised his right hand and released the Thirty-Nine Binding Spell Round Gate.

The invisible sound waves materialized, tearing everything in their path to shreds with their unreasonable and violent power. They struck the oval shield head-on, instantly producing a creaking sound.

In the distance, Jushiro Ukitake held a sword in one hand, absorbing all the impact of the sound waves. Behind him lay the unconscious Sentaro Tsubaki.

Such intense aftershocks of battle were still a bit too much for this Grim Reaper who wasn't even a vice-captain.

"Kong, don't hesitate, run!"

"These are fragments of the Spirit King that Tsunayoshi Taketori secretly collected. Driven by some unknown force, they went completely berserk."

"And its spiritual pressure is locked onto you alone!"

Jushiro Ukitake coughed up a mouthful of blood, but still insisted on finishing his sentence in one breath.

He was afraid that his junior brother would act recklessly like before.

It's important to understand that the power of the Soul King is completely different from that of Gosuke and Tsunayoshi Taketori.

Naraku Sora took a deep breath, his expression gradually becoming serious.

It was pretty much as he had guessed; the scene he had just witnessed did indeed resemble the image in his memory.

Yhwach absorbed the Soul King's body, and the excess power spilled out into the Soul Society, instantly transforming into an endless torrent of monsters that devoured the Shinigami in the ruins.

How was it resolved back then?

Before he could think any further, the bull's head drooped, and its two eyes and four pupils simultaneously fell upon Naraku Sora.

The moment their eyes met, an eerie fluctuation began to spread.

It felt as if an invisible blade had pierced my soul; intense pain erupted instantly.

It felt like someone was violently stirring inside my head with a knife.

"cough--"

Naraku Sora, his body hunched over, vomited a pool of dark red blood.

By the time he had finally recovered, a massive shadow had already enveloped and enveloped him.

Eleven arms were raised, and the remaining arm picked up the Zanpakuto that Tsuna had thrown down, unleashing a barrage of attacks.

In an instant, Nai Luo Kong was submerged.

The suppression he had previously achieved through numerical superiority was now being returned to him without reservation.

The spiritual pressure surged like a tide, and the dormant black shadow became active again, gathering on the arm and blasting out without any error.

The figure was sent flying backwards in an instant, shattering the barracks and sending up clouds of dust.

With both arms bent as if drawing a bow and arrow, a large amount of spiritual energy gathered to form a deep blue spiritual bow and arrow.

Fully charged, unleash!

The arrows whistled as they pierced the air, falling straight into the collapsed ruins.

Just as the arrow was about to hit Nai but missed, a familiar, undisguised voice suddenly rang out nearby.

"Binding Path No. 81: Severing Emptiness".

An invisible, solid barrier descended from the sky, blocking the arrows without any doubt.

The shattered spiritual particles were directly deposited on the broken void.

Unwavering.

Naraku Sora turned around in surprise.

A figure enveloped in curved light emerged from the darkness, its familiar brown wisps flashing by before being enveloped once more by the light of the Kido.

"Don't just stand there like an idiot."

An urging voice rang in my ears, "Seireitei is not suitable for our all-out battle. Let's take it to a secluded spot in Rukongai first."

"Let the other captains handle this mess."

Despite the disguised voices that followed, Naraku Sora immediately recognized Aid's identity.

In such a desperate and life-threatening situation, his good brother disregarded the risk of his identity being exposed and rushed to his aid immediately, which was truly touching.

"Next time the prison canteen has a new tofu dish, I'll definitely send it to you as soon as possible."

"?"

Are you sick?

Is this the time to talk about this kind of nonsense?
