The Alchemist in Bleach

Yes, they still haven't grasped the brilliance of Ichiro's move.

As mentioned earlier, both the Hollow Chamber and the Transcendental Gate essentially borrow the power of Hueco Mundo or Soul Society to travel between worlds, but there is a prerequisite.

The entire process of traversing this world must involve that world.

For example, the Black Hole that Ichiro is currently using can be used to travel from Hueco Mundo to the Human World, the Dangai, the Soul Society, etc., but you cannot use the Black Hole directly from the Soul Society to the Human World. You can only go through Hueco Mundo first and then go to the Human World, because the essence of the Black Hole is the power of Hueco Mundo, not the ability of a single Hollow.

This is also why Soul Society has achieved so little in its research on Hueco Mundo over the years. Hueco Mundo has a shielding effect on other worlds, making it difficult to even detect, let alone borrow its power so easily.

Not to mention turning this power into one's own; in essence, this is the highest level of simulated world!

Going further up, one enters the realm of creation, which is naturally not so easy to succeed in. This is why Ichiro said that even if the energy level of the Kido Techniques developed by Hikifune and the others were several levels higher, it wouldn't work; the gap was simply too great.

What Ichiro is doing now is to open a black cavity from the Universal World, a black cavity that is directly connected to the black cavity they came from. The whole process does not actually reach Hueco Mundo.

This means that if we go further back in our research, Ichiro could very well make history in the Soul Society once again!

However, they misunderstood. With the help of the Spirit King, Ichiro might have a chance to accomplish this, but it's only a chance. He is actually just using the characteristics of the Myriad World itself, which can be considered another development of the Myriad World for him.

Simply put, the Universal World is temporarily simulated to resemble Hueco Mundo, thus directly connecting with the Black Hole from which they came. The reason for not opening a new one is that since the Universal World is now simulated to resemble Hueco Mundo, it would trigger the alarm system of the Thirteenth Division, which would be creating trouble for no reason.

However, these brutes from the Eleventh Division didn't know that; all they knew was, "Awesome!"

It's just awesome!

Everything I say is awesome!

Don't ask, I'm out of words!

However, upon returning to Soul Society, they discovered something even more outrageous, something that even they understood was enough to be recorded in the history of Soul Society!

No one died in this battle!

The most serious injuries were only minor!

Since the establishment of the Thirteen Teams—no, since the creation of Soul Society—there has never been a battle of such scale with zero casualties!

Even today!

For a moment, the Grim Reapers, realizing this, fell silent. At that moment, they all remembered what Ichiro had said on the way there. He said that he would not participate in this battle directly, but would act as an assistant so that they could fight with peace of mind and make the most of their abilities.

At the time, they still felt quite regretful, because based on Ichiro's Kido strength that they had seen, as long as they held the line, Ichiro would definitely be able to play a huge role!

As for support, isn't that the job of a medic?

How useful can it be?

However, Ichiro made them realize what truly makes a great support player...

At this moment, everyone suddenly realized that what had happened in the battle just now seemed to be something they could probably do as well.

Because these effects seem to be similar to both the Return Path and the Binding Path, with the Return Path having the most. The Eleventh Division doesn't know much about the Binding Path, but they do know the Return Path. In fact, in the current Seireitei, very few Shinigami don't know the Return Path; they remember that there are Return Paths with similar effects.

Does this mean that even without Ichiro, they can still fight a satisfying battle like this?

After returning to Soul Society, they didn't rest for long before throwing themselves back into battle against Hollows. The difference this time was that without Ichiro's buff, they felt a bit strained.

As the saying goes, it is easy to go from frugality to extravagance, but difficult to go from extravagance to frugality. Now, although they have only been separated for a short time, they have already begun to miss Ichiro, which has accelerated the spread of the feat of zero deaths in this battle.

In just a few days, the concept of auxiliary treatment has taken root in people's hearts, and a complete set of standardized theories has been quickly compiled. There are three reasons for this rapid progress.

First, this battle resulted in zero casualties, a first in the history of Soul Society, setting a precedent and demonstrating to all Shinigami the dominance of powerful support abilities on the battlefield.

Second, the Soul Society itself has auxiliary abilities and tactics, such as the Binding Path, which is mainly for support. However, unlike Ichiro, it does not entrust it to a Shinigami to be responsible for, making it independent.

The Third and Fourth Divisions' instigation also played a role. Although Ichiro sometimes gets carried away and likes to act recklessly, most of the time he prefers to plan carefully before acting. The concept of support was something he had planned long ago, which is also reflected in the return journey. After all, this can greatly improve the status of the Fourth Division, and incidentally, the status of the Kido Sect is also improved.

Of course, Ichiro benefited the most from this incident. As the one who proposed the concept of support, and given the terrifying performance of Ichiro's Zanpakuto on the battlefield, it is considered the strongest support Zanpakuto in Soul Society!

Don't let the name fool you; it's a huge honor in Soul Society. Currently, only the Captain-Commander's Ryujin Jakka has received this evaluation—the strongest fire-type Zanpakuto in Soul Society. (Note: At this point, Haku should not have awakened yet.)

However, none of this concerned Ichiro, and he knew nothing of these matters. Upon returning to Soul Society, he and Urahara Hikifune immediately rushed back to the laboratory, partly for experiments, and partly to verify a troubling suspicion in his mind…

......

In the 12th Division laboratory, Ichiro and Urahara watched the images formed by the information transmitted back from the seal, remaining silent.

"So, you mean this isn't his real appearance?" Urahara frowned, pointing at the thin man in the image, somewhat troubled. The other party wasn't that stupid; he didn't take the Hueco Mundo fragment directly, and the cut was quite clever, just avoiding the positioning spell set up with the Soul King's power.

I thought I'd at least get a good appearance, so it wouldn't be a complete loss, but who knew...

"Hmm, no, did you see the two Zanpakuto at his waist?" Ichiro frowned as well. He had noticed something was wrong in the black cavity. The slightly chubby Shinigami he had been focusing on disappeared the moment he entered the black cavity. That's why he had this idea. "There should be a mimic Zanpakuto in there. Its ability is transformation, and a very high degree of transformation at that!"

Even in my current state within the myriad phenomena world, I couldn't discern his true nature!

"Why did you have to invent a mimicry Zanpakuto? Isn't that just aiding the enemy?"

"Is it my fault? Try defending against the Great Spirit Book Corridor! Besides, you invented the Transcendental Body; isn't that thing even more influential?" Ichiro had long anticipated that the appearance of the mimicry Zanpakuto would attract Aizen's attention, but he hadn't expected that guy to obtain it so quickly, and even improve the technology...

"However, on the other hand, isn't it true that a mimicry Zanpakuto can't simulate the rule system? You can't possibly not distinguish between a simple illusion or a Kido system in the Universal World. The only thing that can do that is the rule system, and only a rule system that has evolved to a certain level!"

"So, this is the enemy we're facing."

Their strength, intelligence, and strategy are all top-tier; they're truly difficult to deal with...

Chapter 162 The Dilemma of Squad Zero

Although Aizen's keen insight was somewhat beyond Ichiro's expectations, it was still alright, because from the very beginning, Ichiro did not believe that he could follow the original plot and kill Aizen.

Responding to each move as it comes, isn't that the most basic thing?

However, what Ichiro was curious about was how Aizen managed to create a rule-based mimicry Zanpakuto and achieve such an incredible speed of evolution.

He was very envious of this technology, which is exactly what the current mimicry Zanpakuto desperately needs. If he could forge a rule-based Zanpakuto, many problems would no longer be problems. For example, rule-based Zanpakuto—immunity to illusions, and the Great Remnant of Kyoka Suigetsu!

For example, within a certain area, life forms are not allowed to evolve, resulting in a massive collapse and destruction!

For example, in a certain area, the Kido technique cannot be used. Blue... well, this Ichiro is seriously injured, we need to find a way to avoid this situation.

Aside from the rule-based mimicry Zanpakuto, there's another one that accelerates the evolution of Zanpakuto, which is also very useful to him. With his current strength, the Demon Dragon and the Southern Bird Sparrow are gradually falling behind him. The Southern Bird Sparrow is alright, but the Demon Dragon is seriously lagging behind. If this continues, it will really become a means of transportation.

While this isn't bad, it's always good to have something stronger.

However, this needs to be done gradually; there's no rush for now.

Actually, exchanging with the Tsuna-Yayo family is the fastest and easiest way, since they have access to the Great Spirit Book Corridor, and Aizen's technology is also inside.

However, this could easily expose Aizen's existence. Nobles, you never know what they're thinking. What if they're colluding with Aizen?

This is not impossible...

Therefore, finding a way to enter the Great Spiritual Book Corridor is the most important thing, and we also need to find a way to eliminate the Tsunayo family!

The status of the five noble families is not unshakeable. In the original work, the Shiba family was driven to Rukongai. Since one of them has to leave, why can't it be your Tsuna-Yashiro family?

However, those are all things for the future. Right now, the most important thing is to focus on the three major research projects at hand: black cavity shielding barrier, black cavity reverse membrane control technology, and virtual circle detection technology.

Because of this battle, the Hueco Mundo expedition may not be launched, which reduces Ichiro's pressure and allows him to focus on his research. However, the workload for the other two research projects is considerable, so overall, they are still very busy.

……

A week later, amidst the excited gazes of the researchers, the black cavity they had artificially opened slowly closed under the effect of the killing intent stone's simulated spell.

A smile appeared on Ichiro's face, but it wasn't time to be happy yet. Ichiro calmly continued to give instructions: "Group one, maintain the fluctuation simulation technique; Group two, check if the black cavity technique has changed."

"Yes! Ichiro-sama!" x2

……

"The procedure is working normally."

"The two surgical procedures are operating normally."

"..."

"Oh oh oh!! We did it! Hahaha! We really did it!"

After a moment of silence, everyone cheered loudly, not only because their tireless research over the past week had yielded results, but more importantly, because this research was destined to be recorded in the history of Soul Society!

This is a tremendous honor for any researcher!

How could they not cheer?

Therefore, even Ichiro did not interrupt them again. He simply stood there, quietly watching them, as if he had returned to the situation when he was conducting research in his previous life.

They were the same way back then. In addition to carrying out the tasks assigned by their superiors, they were also responsible for leading the team to study the research tasks assigned by their superiors. Every time there was a breakthrough, everyone would cheer like this.

We share our sorrows, we share our joys...

Looking back, this was the first time he had led a team to tackle a project since arriving in Soul Society. It felt pretty good. Maybe he could do one in the Fourth Division?

Ichiro kept this idea in mind, clapped his hands, and interrupted their cheers.

"Alright everyone, let's stop the cheering for now. Let's go and do the final experiment. Success here is nothing special; success in Rukongai is the real success. We're still a long way from officially putting it into use. Let's keep going!"

"Oh!!!"

After cheering like monkeys once more, everyone turned around and packed their things with smiles, preparing to head to Rukongai for the experiment. The Killing Intent Stone Simulation Technique was only in its initial stages, and a large amount of data still needed to be adjusted.

After all, the laboratory environment is only in an ideal state to ensure the development of surgical techniques. In actual use, adjustments are needed based on various unforeseen circumstances.

However, at this point, it's basically finished. The rest is just a lot of revision work, so there's no harm in celebrating.

Soon, everyone packed their things. Monkey King, no, Ichiro, led everyone to Rukongai No. 30. From here on, the influence of the Seireitei's killing intent stone barrier was almost gone. However, the Shinigami patrols here are usually quite strict, and the Thirteenth Division can sense any Hollow traces immediately. Therefore, Hollows rarely appear here.

However, a small number does not mean a lack of resources, so it is quite suitable as an experimental site.

……

In Rukongai No. 30, after a group of people had prepared their spells, Ichiro nodded and crushed the sphere in his hand. This was a spirit powder made to resemble the bait used by Quincy to attract Hollows. Normally, this thing was wrapped in a transparent object, but once crushed and dispersed, the powder inside could attract Hollows across boundaries.

This was something Ichiro made on a whim when he was looking for inspiration. It's not very effective against Shinigami, since it can only attract weak Hollows with average strength.

However, it's enough for experiments. The black cavity torn open by the Hollow is difficult to stop with just a technique; in that situation, you can only fight back.

The technique currently being developed can only prevent ordinary Hollows from opening their black cavities, thus preventing them from freely launching attacks from the small alternate dimensions attached to Hueco Mundo.

"Tear~"

Soon, countless dark cracks appeared in the sky above Rukongai, from which a large number of Hollows emerged. Hueco Mundo was already mobilizing to invade Soul Society, and a large number of Hollows were lining up to come in and die.

Ichiro's Spirit Powder is now like a lighthouse in the ocean, instantly pointing them in the right direction. Otherwise, with the effectiveness of the Spirit Powder, it might not have been able to attract so many Hollows.

"Lord Ichiro, the experiment has failed and cannot be shut down."
