Death: Starting as the Guardian of Avici Hell

For example, the Red Fire Cannon, which was used most frequently.

Even with the incantation broken, Naraku's Crimson Fire Cannon remains undamaged and is even stronger than others' fully incantated versions.

This can only be achieved by perfectly comprehending a demonic path.

If it were just one or two, Aizen wouldn't be too surprised, but Naraku has been able to achieve this standard with all the Kido he has released since the start of the battle.

This was somewhat unexpected.

However, just as Aizen was surprised, he suddenly realized that something seemed off about the floor beneath his feet, and in the instant he subconsciously looked down to check—

A dazzling flame shot straight into the sky, and in an instant, a rumbling thunder followed, the blazing light engulfing the unsuspecting Aizen.

The brilliance and splendor are condensed and bloom in splendor at this moment!

At the critical moment, Aizen instantly used the technique "Severing the Void," and a solid, invisible barrier appeared out of thin air, easily and steadily blocking most of the howling rays of light.

Some of the missed impacts were easily annihilated by the overwhelming spiritual pressure.

When everything calmed down, Aizen frowned and looked at the location where the Kido had erupted. Some Kido spiritual pressure remained on the charred floor.

Judging from the traces, it is indeed a newly constructed trigger-based ghost path.

Aizen's mind flashed back to the battle, replaying Naraku Sora's figure frame by frame. Finally, during a Shunpo dodge, he caught the abnormal spiritual pressure beneath Naraku's feet.

"Sōsuke, is the way of the demons such an inconvenient thing?"

Naraku Soryu grinned and said smugly, "Besides using my feet, I can even unleash Kido with my head, though it's not very aesthetically pleasing."

"But we Grim Reapers have never been concerned with trivial matters. Come, let's start from the beginning."

Aizen: "..."

He's now hesitant about whether to continue studying.

Chapter 70 Ishikawa Sosuke's Relief

After much deliberation, Aizen decided to give up.

Mastering trigger-based Kido is enough; releasing Kido with one's head is a bit too much of a stretch for him.

Associating with this guy is already bad enough to damage one's reputation; if I were to learn some of his unique skills, I'd probably be completely led astray.

"Let's talk about Tsunayoshiro."

Aizen's expression relaxed slightly, no longer dwelling on the matter of trigger-based Kido. With his talent, he would master this technique in no time.

As for putting that ghost's head into the ghost realm, let's put that aside for now.

"The corresponding strategy still needs time to be laid out. Before that, let's talk about a discovery I made unexpectedly."

Aizen raised his head, his calm gaze fixed on Naraku Sora. Sunlight streaming through the window shone on his thin, non-prescription glasses, obscuring the expression in his eyes.

"Kong, come with me."

As soon as he finished speaking, Aizen reached out and wiped away the remaining traces of the triggered Kido in the dojo, and a heavy spiritual pressure, as deep as an abyss, vanished in a flash.

After confirming that there were no remnants, he walked out of the dojo, and Naraku Sora followed curiously.

The two walked one after the other in the barracks, attracting greetings from many team members.

They were already familiar with this head officer of the Central Prison who frequently visited the Fifth Division.

Moreover, after hearing about the things Naraku Sora had done, many Shinigami admired him greatly.

Almost no Grim Reaper would dare to draw his sword against a nobleman.

Even if they exist, and they act in accordance with the laws of Soul Society, those who target nobles will soon disappear from Seireitei.

On the other hand, Naraku is not only perfectly fine, but he has also risen through the ranks and is now the third seat in the Shinigami Prison, making him a highly sought-after figure in Soul Society.

In addition, he is honest and doesn't talk much, so many Grim Reapers regard him as an object of their admiration.

As for Aizen, who was standing next to him, he had an even better reputation within the Fifth Division.

He is kind and composed, reliable and dependable in his work, and an expert at handling team affairs, easily resolving even the most difficult documents.

The title "Dragon of Documents" wasn't given by the captain or vice-captain; it was chosen by the unanimous approval of the team members.

No one is more deserving of this title than Aizen.

After reporting to the Shinigami stationed in the executive office, Aizen left the Fifth Division with Naraku.

On the wall of the barracks, a figure leaned against the cold bricks, a blade of grass dangling from its mouth, its long, golden hair flowing loosely, its lazy gaze watching the two figures depart.

"The Central Prison?"

"Tch, friendship? I don't envy that kind of thing at all..."

With that, the man jumped down from the wall and walked into the barracks.

However, after they left, the two figures heading towards the True Central Prison disappeared into the air like bubbles, never to be seen again.

It was as if it had never existed.

Runlin'an, outside the city.

Naraku Sora curiously surveyed his surroundings.

The bright and clean room was filled with sophisticated equipment and instruments that were rarely seen even in the research labs of the Shinigami Prison.

Inside the enormous container, filled with a dark green liquid, floated a familiar figure that should have been shattered into dust, eyes closed, its body covered with numbers and patterns completely incomprehensible to the average person.

Naraku Sora grinned upon seeing this, saying, "Isn't that Ishikawa-kun who attacked us before? I remember I completely shattered him, didn't I?"

"Sousuke, I didn't expect you to be able to do super assembly."

Aizen: "?"

Before bringing this guy here, he had thought that Naraku Sora might not be human, but he didn't expect him to be this sick.

What is Super Assembly?

"Actually, I brought you here mainly to tell you some things."

Aizen suppressed his agitated blood pressure and said seriously, "I started preparing for scientific experiments back when I was in the Spirit Arts Academy."

"Because the research topic is too taboo, the laboratory was built in the outer area of ​​Rukongai."

"Do you have anything to say about these things?"

In fact, he had the idea of ​​revealing his true colors as early as when Naraku Sora taught him all his demon sword techniques, but due to certain reasons, he had not found a suitable opportunity for a long time.

Now that he had received this gift from him once again, Aizen made up his mind to tell him all these forbidden things.

As for how Naraku Sora will choose, Aizen has already made preparations.

At worst, leaving Soul Society for the human world or Hueco Mundo is also an option, it just takes a little more time.

Was the attack clean?

"?"

"I mean, no one else noticed?"

"..."

Naraku Sora's thought process was so peculiar that Aizen's brain momentarily went blank, and he didn't know how to answer.

He took a deep breath, calmed himself, and said seriously:

“Using Shinigami for experiments is a taboo under the laws of Soul Society. Violation of this law can result in the loss of all spiritual power, exile to the human world, or being banished to the other world.”

"In severe cases, they may be imprisoned in the Avici Hell or executed."

"As the warden, aren't you going to do anything after seeing all this?"

Naraku spread his hands and said helplessly:

"The regulations also prohibit disrespecting superiors and infringing upon the interests of nobles. Do you see me doing that?"

“If we were to act in accordance with the law, we shouldn’t have taken action against the Araki family back in the Paradise House. Instead, we should have reported to the 46th Chamber and waited for the secret order to be issued.”

"Sousuke, do you think I'll wait?"

Aizen remained silent.

"Besides, the people you're using for research aren't just anyone, they're our old acquaintances."

Naraku Sora stood beside the container, patted the outer wall, and grinned, saying, "If Ishikawa-nii knew this from beyond the grave, he would surely be pleased."

"By the way, why is there another arm here?"

Just as Aizen was deep in thought, Naraku Sora noticed a thick arm floating in the dark green liquid.

"Takeda Satoru".

Aizen gave someone a complicated look, then simply changed the subject:

"I was the one who attacked him earlier. I underestimated this guy's strength, which is why I couldn't finish him off on the spot. But at least it wasn't a complete loss."

"And that's exactly what I wanted to tell you."

As he spoke, he approached the equipment, his ten fingers moving swiftly across the sophisticated surface, blurring into a blur of motion. Soon, a massive light screen appeared in mid-air.

In the image, Takeda Satoru's arm is dissected and broken down, from hair to blood vessels, and then to the deeper distribution of spiritual particles.

The corresponding positions also include detailed specifications for various parameters.

"After a period of research."

Seeing that Naraku seemed genuinely unconcerned about the so-called forbidden research, Aizen regained his composure, his glasses reflecting an inexplicable light, and a faint air of confidence emanated from him.

“I found phosphorus in his arm.”

Chapter 71: Lacking a memory compared to others

Phosphorus?

Naraku Sora frowned, a thoughtful expression on his face.

I feel like I've heard of it somewhere before, but it doesn't really stick in my memory.

My past life memories are a jumbled mess, including many taboo books related to death. I may have seen this concept somewhere before, but it's been too long.
