Bleach: From the moment I was invited by Squad Zero

"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's brows furrow slightly.

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

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

Based on his understanding of figures like Yamamoto Genryusai Shigekuni, ordinary internal murders, even those 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.

"For Captain-Commander Yamamoto to join forces with Kuchiki Ginrin... this is probably more than just a simple murder."

Liu Chuan silently noted down this suspicious point. The Kuchiki family, the head of the four noble families, and the truth they were covering up in collaboration with the Captain-Commander... This pool of water is much deeper than it appears.

Continue browsing the chapters about the Quincy, which carry a grander yet 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 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, Wo Ling Tiezhai, and the deputy demon master, You Zhaotian Bo Genjun, were implicated in this 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 and threat to 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 virtual transformation 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 four noble families, the captain of the Second Division, betray Soul Society to save him... is definitely not just an ordinary genius or madman.

"The simultaneous involvement of the Grand Master and Deputy Grand Master of the Ghost Cult resulted in the Ghost Cult being leaderless; nearly half of the captains and deputy captains were implicated; and it ultimately ended with the four 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 an 'experimental accident' or 'personal ambition.' The forces and secrets involved are probably beyond imagination."

Unfortunately, almost all of the parties 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 engage in high-density, physical communication and battle with its wielder."

Theoretical benefit: It greatly shortens the time required for Shinigami to comprehend, master Shikai, and even reach the threshold of 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 the surface of a lake where a stone had been thrown in, suddenly creating ripples!

The mystery of Hyōrinmaru's "twins" lies in the incomprehensible 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 record about the "transformation of the 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 something like this! Let the Zanpakuto explain itself!"

He rubbed his hands excitedly: "But this is something that Kisuke Urahara came up with, the technology must be amazing, and it's under control. Where are we going to get it? The Technology Development Bureau? Mayuri Kurotsuchi, that madman, is not easy to deal with."

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

"The Technology Development Bureau is an essential step. But before that, we need more information on Kisuke Urahara's other related research."

"That makes sense!" Shiba Ichishin nodded vigorously.

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 take advantage of the "Transformation God Body," they can't get around the Technology Development Bureau no matter what.
