Death: Starting as the Guardian of Avici Hell

The former's face was full of eager anticipation; as he rubbed his hands together, he didn't forget to ask:

"Is Mr. Aizen really ready?"

Aizen glanced at him and said in a deep voice, "I already observed it in the laboratory. With my current spiritual pressure level and soul strength, it is more than enough to easily contain the Hogyoku."

"Considering that I was the one who led the Hogyoku experiment, it has the highest level of recognition for me."

"With the addition of a large number of Spirit King fragments as a backup plan, there is almost no possibility of failure."

While the two were talking, Mayuri Kurotsuchi had already assembled the equipment. The device, which resembled a game console, landed on the ground and simultaneously played multiple frequencies.

This is used to capture data changes in spiritual pressure, spirit body, and soul during the fusion process, for use in future projects.

There's only one Hogyoku; once you miss it, it's gone forever.

After making a quick adjustment, Aizen opened the sealed box. After thinking for a few seconds, he finally decided to use the Hogyoku to disassemble the Soul King's right hand.

As a symbol of authority, the Spirit King's right hand possesses even greater power.

If it could be absorbed into the Hogyoku, its evolved form would be even more perfect.

This way, you won't fall too far behind someone.

As a dazzling light burst forth, Aizen raised his hand toward the Hogyoku, simultaneously conjuring up the idea of ​​fusion in his mind.

The next second, a huge, heavy beam of light shot straight into the sky, instantly shattering the clouds drifting overhead.

Visible ripples spread outwards in all directions from the center of the beam of light.

Seeing Aizen being swallowed by the pillar of light, his expression subtly changing, Kisuke Urahara said worriedly:

"Lord Naraku, is Lord Aizen alright?"

Naraku Sora pushed up his glasses, which he had pilfered from the lab, and said in a show of expertise:

"Don't worry, even if you don't have confidence in the Hogyoku, you should have confidence in Sousuke."

Kisuke Urahara thought about it carefully and realized that it did make sense.

During his daily experiments, Inzen usually presents a reassuring demeanor.

It seems that no matter what happens, it won't affect him.

However, despite saying that, Naraku Sora was already prepared to kill Aizen at the crucial moment.

In the event of an unexpected situation, stopping the experiment immediately is the right decision.

At most, we'll go to hell again and fish Aizen out.

The main issue is that the current Hogyoku is far stronger than the one in the original timeline.

Not only were there a large number of Soul King fragments mixed in, but the materials used in its creation were also mostly the souls of powerful Shinigami or Hollows.

This can be seen from the fact that the ethereal effect has almost no side effects.

The spiritual pressure beam that shot into the sky grew increasingly dim, and a heavy, profound aura surged forth, sweeping away and obliterating the earth beneath its feet.

Aizen's soul is undergoing a transformation.

The process of fusing with the Hogyoku was not as peaceful as expected. On the contrary, extreme pain erupted from the depths of the soul, as if countless blades were cutting through it.

Even with his strong will, he still found it difficult to bear.

But to avoid being laughed at by someone, Aizen maintained a calm expression throughout, as if nothing had happened.

Their determination was almost frightening.

"The soul index is soaring at an incredible rate, the spiritual pressure is completely beyond the observation range, and even the spiritual body value is constantly getting stronger."

Mayuri Kurotsuchi, who was standing guard in front of the equipment, stretched his lips to his ears, revealing a set of perfectly aligned gold teeth:

"Hehe, it'll be over soon."

As if to confirm his words, the moment he finished speaking, the enormous pillar of light completely subsided and disappeared into Aizen's body, marking the end of the Hogyoku fusion experiment.

Aizen slowly opened his eyes, a flash of incandescent light appearing and disappearing in his pupils. A suffocating pressure descended suddenly, only to vanish in an instant.

He spread his hands, carefully sensing the unprecedented abundance of power within his body.

The most obvious point is that the spiritual pressure, which was originally stagnant, is now increasing at an unbelievable speed, as if there is no limit.

"How do you feel?" Naraku Sora came closer, looking at her curiously.

After merging with the Hogyoku, Aizen's appearance did not change much, except that a faintly glowing gem was embedded in his open chest.

His eyes turned into black with golden pupils, somewhat similar to his ethereal state.

"fantastic."

Aizen slowly closed his palms, and a milky-white, tangible spiritual pressure surged out, instantly covering his body.

It forms a layer of white armor, like an insect cocoon.

In this state, his spiritual pressure continued to rise, just like his blood pressure when facing Naraku Sora.

Having prior experience with Hollowfication, Aizen was very adept at controlling this process.

With the addition of the Hogyoku's power, he easily became familiar with the surging spiritual pressure.

Click!

A crack appeared in the white bone armor covering the body, and as if it were some kind of signal, countless cracks appeared, and the sound of breaking rang out one after another.

A completely new Aizen appeared before Naraku Sora's eyes.

Brown hair fell down, and his eyes had a black background with golden pupils. A hole with a Hōgyoku (a type of jewel) inlaid in the center appeared on his chest.

The most exaggerated feature is the three pairs of wings that are fully spread out behind it, making it look like a real god.

"?"

Naraku asked, a question mark appearing on his face.

What happened?

How did we skip the first three stages and arrive directly at the fourth stage in our memories in the blink of an eye?

Sousuke, have you opened it yet?

"Would you like me to help you get used to the strength?"

Naraku Sora was eager to try.

Aizen glanced at him, then refused expressionlessly:

"With the Hogyoku, I can perfectly control all my abilities and powers without having to adapt."

Despite surpassing this guy in spiritual pressure once again, the rules of the Shinigami simply do not apply to Naraku Sora.

Spiritual pressure cannot be used as a standard to measure combat strength.

If a fight really breaks out, the outcome is hard to predict.

Most importantly, he could clearly sense that the evolutionary process had not ended and that the Hogyoku was still playing a role.

As the level of integration increases, there should be one or two more phases to come.

We'll settle the score when we've truly reached the end of evolution.

He wanted a close, evenly matched battle, not a one-sided, crushing defeat.

I just don't know if this guy will suddenly become stronger again by then.

Logically speaking, the stronger an entity is, the more difficult it is to improve its strength.

For example, Hyosube Ichibei, Yamamoto Shigekuni...

But Narakuku obviously cannot be judged by common sense. This guy is a complete monster, and his purpose in appearing is to negate the conclusions that others have painstakingly researched.

Aizen's feelings were inevitably complicated.

However, this feeling of chasing after others seems pretty good.

Thinking of this, a barely perceptible smile appeared on the corner of his mouth.

……

……

For the next period of time, Naraku's life became dull and boring again.

He eats, sleeps in the Second or Fourth Division, gives pointers on the training of other Shinigami, and occasionally practices on his own.

Take Kenpachi Zaraki for example.

After gaining the power of etherealization, his already terrifying strength surged once again.

Let alone ordinary Shinigami captains, even Kyoraku Shunsui would find it difficult to confront him head-on without using his Bankai.

However, considering that Kyoraku is not the kind of reckless player, it is understandable.

It's worth mentioning that, perhaps because she went to the Second Division too many times, Yoruichi was worried that she was being overexploited.

So, during a hot spring bath, she recommended her own dowry maid to him—

Soi Fon.

Naraku Sora initially refused, declaring that he would only love Yoruichi in his life.

Yoruichi scoffed, coldly pointing out that someone was clearly uninjured, yet frequently stayed overnight at the Fourth Division, and not in the general medical facility, but in the captain's room.

After being exposed for her scumbag behavior, Naraku stopped pretending to be a gentleman and invited Soi Fon to share the burden with Yoruichi that very night.

To be fair, although Soi Fon is inferior to Yoruichi in terms of figure, she has her own advantages.

Because of years of consistent exercise, the body is extremely flexible and can be posed in various ways, which is fascinating to watch.

In addition, the skin is smooth and firm, with an excellent feel.

During the intense battle, her round, glistening toes curled slightly, gripping the bed sheet, her insteps arched, revealing a beautiful sight.

The only drawback is that as their strength increases, the two of them combined can't defeat him alone, and they are utterly routed every time they fight.

pity.

In the early morning, Naraku Sora left the Second Division barracks feeling refreshed and returned to the Central Prison in a pleasant mood, intending to ask Urahara Kisuke how the remaining Arrancar's second Resurrection was progressing.

However, as soon as they reached the gate, they saw a figure pacing anxiously, as if waiting for something.
