Bleach: From the moment I was invited by Squad Zero.

"The captain of the 11th Division," Yanagawa couldn't help but mutter to Shiba Isshin beside him, who was also browsing and whose expression had become quite interesting.

"It all seems a bit unusual."

From the first captain Retsu Unohana to Kenpachi Kuruyashiki, who refused to join the Zero Division, and Sōya Azumashiro, who attempted to reform the residents of Rukongai, the succession of the Eleventh Division captains is practically an encyclopedia of abnormally strong individuals.

"It's more than just unusual!" Shiba Isshin said in a low voice, his expression strange.

"It's practically a concentration camp of lunatics! Thankfully, the current Kenpachi Zaraki, while also a battle maniac, is at least... uh, at least relatively simple-minded?"

He himself became a little unsure by the end.

Yanagawa shook his head, putting aside for the time being these shocking pieces of information about the past Kenpachi.

He continued to focus his attention on other historical records, especially those related to Squad Zero and technological development.

Soon, another familiar name came into view.

"Captain of the 12th Division, Kiryu Hikifune. Achievements: He pioneered the basic theory of 'Gi-soul' and based on it, he initially constructed the conceptual framework of 'Gi-boku'. Due to his pioneering contributions, he was promoted to a member of the Zero Division."

I will probably meet this senior in the Spirit King Palace soon, Liu Chuan silently noted.

Chapter 18 Transformation into Divine Body

"The Kuchiki Hibiki River Sealing Incident..." Yanagawa's gaze lingered on this record.

Information indicates that Kuchiki Hibiki, son-in-law of Kuchiki Ginryu (the grandfather of the current 6th Division Captain Kuchiki Byakuya), was sealed in the present-day Karakura Town by Captain-Commander Yamamoto and Kuchiki Ginryu after killing three colleagues.

The record ends here, concise, cold, and in accordance with the standard format of official archives, but Liuchuan felt puzzled at this moment.

"To kill three colleagues, would it require Captain-Commander Yamamoto to personally intervene and join forces with the head of the Kuchiki family, one of the five great noble families, to seal them away?"

"This record is far too evasive, and even somewhat of a cover-up."

Based on his understanding of Captain-Commander Yamamoto, a typical internal murder, even one involving nobles, would never easily alarm the Captain-Commander to personally carry out the sealing.

Unless, the things that this "Kuroki Echo River" has done, or the power or threat he represents, have become so serious that they could shake the foundations of the Seireitei.

Or it may have touched upon some taboo that must never be made public. And the charge of "murdering three colleagues" is likely just the tip of the iceberg, the most insignificant part of the story.

"The fact that Captain-Commander Yamamoto and Kuchiki Ginrin could join forces... suggests that this involves far more than just a simple murder."

Yanagawa silently noted down this suspicious point. The Kuchiki family, one of the five great noble families, and the truth they were covering up in collusion with the Captain-Commander... This pool of water is much deeper than it appears.

Continue browsing the chapters about the Quincy, which carry a more grand yet also more cruel sense of "inevitability".

Since the birth of the Quincy, the Soul Society has been trying to appeal to the Quincy to hand over the power to deal with Hollows to the Shinigami for many years.

The Quincy refused to accept this situation, and as time went on, their numbers increased, making the cycle of souls even more unstable.

This forced the Shinigami to eliminate the Quincy in order to maintain the balance of the world, and the remaining small number of Quincy were also closely monitored.

To "maintain the balance of the world." Yanagawa pondered these words.

This is undoubtedly an explanation that is both necessary and justified from the perspective of the Soul Society and the Shinigami.

The Quincy's method of completely eliminating Hollows disrupts the cycle of souls and threatens the stability of the three realms, therefore they must be eliminated.

Logically, it seems impeccable, but what is revealed between the lines is the cold and resolute nature of genocide and the victor's one-sided writing of history.

Then, a record of an event that was more recent in time and had a more far-reaching impact captured his full attention.

It is even directly related to the Oni-do sect to which he belongs.

"Kisuke Urahara's Hollowfication Experiment Incident".

Key figure: Kisuke Urahara, former captain of the 12th Division and director of the Technology Development Bureau, who leads dangerous "Hollowfication" experiments.

Direct participants/victims include: Captain Hirako Shinji of the 5th Division, Lieutenant Hiyori Sarugaki of the 12th Division, Lieutenant Lisa Yadomaru of the 8th Division, Vice-Chief Kido Ushōda Hachigen, Captain Kensei Muguruma of the 9th Division, Lieutenant Haku Hisanami of the 9th Division, Captain Raibu Aikawa of the 7th Division, and Captain Rōjūrō Otorihashi of the 3rd Division...

This list is truly shocking, encompassing almost a third of the high-ranking combat force of the Gotei 13 at the time, including several captains!

The great demon master, Kōrō Tessai, and the deputy demon master, Yūshōda Hachigen, were involved in the matter, and later both disappeared.

The incident was characterized as follows: the experiment went out of control, resulting in the Hollowfication of several captains and vice-captains, which was regarded as a major betrayal of Soul Society.

Subsequent developments: Kisuke Urahara was sentenced to a heavy prison term.

At a critical moment, Yoruichi Shihōin, the head of the Shihōin family, the then captain of the 2nd Division and commander-in-chief of the Onmitsukidō, openly broke into the Central 46 and forcibly rescued Kisuke Urahara. The two then defected and their whereabouts are unknown.

All the other victims of the phasing out have also disappeared.

As Liu Chuan read this information, a slight ripple stirred within him.

He had heard about this matter when he joined the Ghost Path Clan, but the details were so horrifying and the implications so wide that they were beyond his imagination.

Kisuke Urahara... someone who could alarm so many captains to participate in his dangerous experiments.

Finally, someone who could make the head of one of the five great noble families, the captain of the Second Division, betray Soul Society to save him... is no ordinary genius or madman.

"The involvement of both the Grand Master and the Deputy Grand Master resulted in the Ghost Path Sect being leaderless; it affected nearly half of the captains and deputy captains; and it ultimately ended with the five noble family heads breaking out of prison and defecting..."

Liu Chuan quickly reviewed the situation in his mind.

"The Central 46th Bureau's final handling of this matter seemed swift and decisive, but the disappearance of many key figures was a factor."

"The true motives behind the incident, the specific content of the experiment, and the detailed process of the loss of control are all vague and unclear in the records."

"This cannot be simply summarized as a 'laboratory accident' or 'personal ambition.' The forces and secrets involved behind the scenes are probably beyond imagination."

Unfortunately, almost all of the people involved have disappeared or lost contact, making it impossible to conduct an in-depth investigation.

Yanagawa temporarily shelved this enormous mystery, but the name Kisuke Urahara, and the dangerous yet advanced wisdom he represented, were deeply imprinted in his mind.

He continued browsing other technical records related to Kisuke Urahara.

The former head of the Technology Development Bureau left a rich legacy, with a dazzling array of ingenious ideas and inventions.

Suddenly, a brief description of an invention flashed through Yanagawa's mind like a bolt of lightning in the darkness.

"Transformation God Body. Inventor: Kisuke Urahara. Original design purpose: Through a special structure and spiritual particle activation, the 'body' of the Shinigami's own Zanpakuto is temporarily materialized in reality, forcing it to communicate and fight with the wielder in a physical form."

Theoretical benefit: It greatly reduces the time required for Shinigami to master Bankai.

Note: This technology places extremely high demands on the user's spiritual power, mental strength, and compatibility with their Zanpakuto, and carries the risk of backlash. The specific manufacturing technology has been classified as a controlled item.

To materialize the Zanpakuto itself?

Liu Chuan's gaze was fixed on these few lines of description, and his thoughts were like ripples spreading across a lake after a stone was thrown in!

The mystery of Hyōrinmaru's "twins" lies in the inexplicable repetition of the Zanpakutō itself.

Existing investigations, whether by interviewing those involved or reviewing history, all revolve around the human element.

But what if we could communicate directly with the core of the problem, the Zanpakuto Hyōrinmaru itself?

What if we could replicate or improve Kisuke Urahara's "Transformation Body" technique, not to aid in training, but to "summon" Hyōrinmaru's true form?

Let that (or those two?) Zanpakuto, which is said to be the strongest ice-type sword, speak for itself and explain why it chose two masters at the same time.

Or at least, can we discover the truth from its concrete form and expression?

Once the thought arose, it spread like wildfire in Yanagawa's heart.

Compared to blindly guessing, directly talking to "Hyourinmaru" is undoubtedly a more direct and closer approach to the essence of the matter!

Although it is technically difficult and risky!

“Captain Isshin.” Liu Chuan suddenly spoke, his voice exceptionally clear in the silent corridor.

"Hmm? What's wrong? What did you find?" Shiba Isshin, who was idly counting the glowing grids on the wall, immediately came over.

Pointing to the passage about "transformation into a divine body," Liu Chuan quickly and clearly explained his concept:

"...If we can manage to reproduce or understand this technology and apply it to Hitsugaya and Kusakabe's Hyōrinmaru, we might be able to bypass all the intermediate steps and seek the answer directly from 'Hyōrinmaru' itself."

Zhibo listened intently, his eyes widening as the boredom on his face vanished, replaced by intense astonishment, which then transformed into strong interest and agreement.

He slapped his thigh: "Yanagawa! What's wrong with your brain? How could you even think of such a trick! Let the Zanpakuto explain itself!"

He rubbed his hands excitedly: "However, this is something that Kisuke Urahara came up with, so the technology must be quite advanced, and it's under control."

Where are we going to get it? The Technology Development Bureau? That madman Mayuri Kurotsuchi is difficult to deal with.

Liu Chuan's gaze calmed down as he quickly weighed the options in his mind.

After leaving the Great Spirit Book Corridor, it's time to meet Mayuri Kurotsuchi, the captain of the 12th Division, who is known as the "mad scientist".

If anyone wants to get their hands on the "Transformation God Body," they simply can't get past the Technology Development Bureau.

Chapter 19 Technology Development Bureau

When Yanagawa and Shiba entered the Technology Development Bureau, the wide corridor was no longer lined with traditional team quarters, but with individual laboratories separated by high-strength transparent materials or special force fields.

The staff inside wore uniform white research coats and were equipped with strange glasses, masks, and other auxiliary devices.

Some of them were performing complex calculations on the floating spirit particle model on the control panel;

Some were recording data on the strangely shaped biological samples in the culture tank;

Some people are even conducting physical collision experiments that look extremely dangerous.

Noisy, busy, and chaotic, yet it possesses a morbid efficiency and frenzy.

Here, there is none of the discipline common to other divisions of the Gotei 13. Instead, there is an extreme pursuit of knowledge and an exploration of the unknown.

Occasionally, researchers would rush by carrying boards covered with crazy formulas, completely oblivious to the arrival of Yanagawa and Shiba Isshin, utterly absorbed in their own world.

"Tsk, every time I come to this place, it feels like I've entered another world."

Shiba covered his nose, trying to avoid a plume of purple smoke coming from the ventilation vent next to him.

After identifying themselves, they were led deep into the Technology Development Bureau by a researcher with a blank stare.

The laboratories here are larger and have more stringent protective measures.

Finally, they arrived at a huge metal door with an extremely exaggerated style.

The gate opened, revealing a spacious interior.

The place is filled with countless instruments, test tubes, culture jars, mechanical debris, biological specimens, and screens displaying crazy amounts of data.

In the center of the room, a cylindrical transparent container immersed in an unidentified green liquid stands out, seemingly containing some kind of special object.

The bubbling sound of liquid echoed in the air.
