Death: Starting as the Guardian of Avici Hell

Naraku Sora took the paper, stuffed it into his pocket without even glancing at it, and grinned:

"I have my own ingenious use for it!"

Chapter 235 You are the mastermind!

Recently, Kisuke Urahara has been in a terrible mood.

As the fourth seat of the Shinigami Prison, he was not like the seat of the Gotei 13, who was busy with various squad affairs files and document organization.

There are no rules or regulations to follow on a daily basis.

His direct supervisor had only one requirement for him: to do his research well and to make the most of his extraordinary wisdom, which was second only to that of someone else.

They developed all sorts of cutting-edge technologies to benefit the Soul Society and the Seireitei.

Because of his love for research, he initially enjoyed it immensely.

But as time went by, when what used to be a hobby turned into work, it became somewhat torturous.

Especially since their own boss is petty and can't tolerate idlers.

They often assign tasks that seem far-fetched to ordinary people, with work periods that can be as long as months or even years.

Kisuke Urahara lodged a strong protest, stating that if things continued this way, he would unleash the invincible Benihime to overthrow the Heavenly Generals.

Then he was severely punished by someone, retaliated with an iron fist.

Although life is somewhat depressing, it's not too bad overall.

As time went by, Kisuke Urahara gradually got used to this kind of life, and even took the initiative to devote himself to some research tasks that were not his responsibility.

When he came to his senses, he couldn't help but feel a little terrified.

Kisuke, Kisuke, how did you become so unfamiliar?

You, who consider slacking off as your life motto, were actually manipulated by some brute?

Don't do this kind of thing!

Just as he was trying to accept this disheartening fact, Naraku suddenly brought a new companion to the Technology Development Bureau.

Formerly the third seat of the 5th Division, now the vice-captain of the 5th Division, Aizen Sousuke.

Kisuke Urahara initially didn't take it seriously.

In his view, Aizen may have some talent in scientific research, but he is definitely not as good as him and Mayuri Kurotsuchi, who have been working in the scientific field for many years.

However, as their contact deepened, Kisuke Urahara was shocked to discover that this man named Sosuke Aizen was anything but simple.

Both in terms of talent and ability, they are top-notch.

Looking across the entire Soul Society, there are few people smarter than him.

No matter how complex the topic or project, as long as it is handed over to Aizen, it can be completed in just a few days, and even more perfectly than expected.

Even Kisuke Urahara couldn't guarantee he could do better.

It was originally thought that the three members of the Technology Development Bureau, with their combined strength, would embark on an epic and inspiring scientific research journey in Soul Society.

However, as they continued to get to know each other, Kisuke Urahara discovered Aizen's wolfish ambition hidden beneath his gentle and humble exterior.

This man is definitely not as simple as he appears.

Given his close friendship with Naraku Sora, the two spent all their time together.

Most importantly, Naraku Sora never doubted Aizen's words.

Thinking about it, that makes sense. Your boss's brain is all muscle, maybe with a tumor at most. He definitely wouldn't be able to see through the true nature of such a cunning person.

Aizen could easily outmaneuver him with a simple trick.

It might not be apparent in the short term, but once the other side reveals its true ambitions, it will surely drag the Seireitei and even the Soul Society into an abyss of no return.

Subconsciously, Kisuke Urahara already regarded Aizen as an equal.

He knew all too well the terrible crisis that would result if someone like him deliberately committed evil.

In order to nip the danger in the bud, he began to investigate Aizen.

However, the other party acted extremely cautiously, making it impossible to find any clues at all.

All indications suggest that Aizen is merely a Shinigami with a slight talent for scientific research, and has no real power whatsoever.

Urahara Kisuke was originally prepared to give up, but during the process of welcoming Naraku Sora back, he suddenly sensed a spiritual energy fluctuation from his leader that did not belong to the Soul Society.

It's a dotted circle!

Urahara Kisuke was stunned.

No wonder he couldn't find Aizen's whereabouts; it turns out he had hidden all his evil deeds within Hueco Mundo.

The most terrifying thing is that one's own leader has been bewitched by the other party and has completely become an accomplice.

This is no ordinary villain.

We must strike hard.

Kisuke Urahara's desire to investigate the truth has never been more urgent than it is today.

He avoided Mayuri Kurotsuchi and secretly developed a black cloak that could perfectly conceal his spiritual pressure.

In this way, they deliberately infiltrated Aizen's private laboratory within the Technology Development Bureau to find evidence sufficient to convict him.

However, despite all their efforts, they still achieved nothing.

Just as Kisuke Urahara was pondering whether to go and investigate Hueco Mundo, he suddenly discovered several documents filled with writing in Sora Naraku's office.

What is this?

Kisuke Urahara knew that his boss didn't like reading, so although he set up a dedicated office in the Technology Development Bureau, it was more symbolic than practical.

Narakuku usually used it to give orders and to make empty promises to his subordinates.

Therefore, this document must be related to Aizen!

Realizing this, Kisuke Urahara quickly checked it out.

The content is not extensive; it merely mentions that there is an undiscovered power deep within the soul of the Void.

as well as.

A wildly imaginative idea.

Gradually, only deathly silence remained in the duty room, along with increasingly rapid breathing and heartbeats.

Before long, a figure draped in a black cloak quietly left the room, concealed by the Curved Light Binding Spell.

In a corner of the corridor unnoticed by anyone, under the barely perceptible glow of the ghostly path, a figure slowly emerged.

Naraku Sora watched the receding figure and a satisfied smile appeared on her face.

Kisuke, you'll understand someday—

I'm the only one in this world who truly understands you.

……

……

For a long time afterward, Kisuke Urahara took time out of his busy schedule to study the contents of the document.

At the same time, we began collecting various materials needed for the experiment.

For example, the most important Hollow soul.

Although there is stock in the warehouse, it is all registered, and if even one item is missing, a thorough investigation will be conducted.

Therefore, Kisuke Urahara began to visit Rukongai multiple times in search of the Hollow who had accidentally invaded Soul Society.

Over the course of several months, he actually managed to acquire a few rare materials.

Although it was only the lowest-ranking Kyrian, it was enough for initial testing.

However, exploring the unknown can be addictive.

Despite Kisuke Urahara's repeated self-admonitions, this kind of private research on how to break the soul boundary between Shinigami and Hollows is a taboo that Soul Society regulations absolutely cannot allow.

But as a researcher, one simply cannot resist the exhilarating feeling of solving a difficult problem step by step.

When the materials ran out and no Hollows could be found in Rukongai, Kisuke Urahara was once again caught in a dilemma.

I rarely see my boss, and all the work has already been done. So, it shouldn't be a problem for me to take a trip to Hueco Mundo during my free time, right?

We might even discover evidence that Aizen intended to rebel!

After careful consideration, Kisuke Urahara pulled out his trump card and opened a black cavity leading to Hueco Mundo in a secluded spot in Rukongai.

Because it wasn't his first time visiting Hueco Mundo, he easily found the materials he wanted in the boundless desert.

A few Kylian birds wandering in the desert.

These enormous creatures, some tens or even hundreds of meters long, resembled giant whales in the deep sea, wandering aimlessly.

With Kisuke Urahara's strength, a few Gillians wouldn't pose any real threat.

He didn't even need to use his Zanpakuto; a few Kido attacks were enough to end the battle.

Not long after, he returned to Soul Society satisfied with the materials he had collected.

Realizing that no one was paying attention to his actions, Kisuke Urahara threw himself back into the experiment.

Having previous experience, he was extra cautious this time when studying taboos.

Not only did they not conduct the experiment within the Technology Development Bureau, they even went to Rukongai to build a new laboratory.

Once it happens the first time, it will happen again and again...

From the initial Gillian to the later Adjuchas, they are mutated Hollows with special abilities.

The harvest is becoming increasingly abundant.

Until they encountered three strange creatures that looked almost identical to humans.

"Recently, Kylian have been going missing in this area. We initially thought it was because an Adjuchas, skilled in killing, had been born, but it turns out to be the Grim Reaper."

The man who spoke had short, blue hair, an arrogant expression, and eyes that revealed an undisguised arrogance and haughtiness. He wore a white uniform and had a knife at his waist.
