Death: This Death is a bit unorthodox.

The reason this child is facing off against Oni Ichijo Kenpachi is so that his subordinates can escape, and he chooses to stay behind to cover their retreat.

They are ruthless to their enemies, but loving to their loved ones.

The former is the reason why I was feared a thousand years ago, and the latter is what I lacked a thousand years ago.

Looking at the young man in front of him, Yamamoto's gaze softened unconsciously.

This child might be able to do even better than me.

As he was pondering, Yamamoto suddenly looked up and gazed at the entrance of the dojo.

"I'm going to remove the barrier now," Yamamoto reminded him.

Seeing that Aozaki Mayuki made a "shut up" gesture, he tapped his cane on the ground.

The soundproof barrier covering the dojo dissipated as spiritual particles.

A figure appeared beside the mountain with a "whoosh" sound, kneeling on one knee.

He was a member of the Riding team responsible for relaying the message.

The Riding team members also spotted Aozaki Mayuki, suppressing their excitement as they lowered their heads, their eyes flashing with admiration.

—This is Aozaki Mayuki, who killed Kenpachi. He is the third seat officer of the Second Division and the pride of the entire Second Division!

Seeing that Aozaki Mayuki was present, he did not rush to speak, but waited quietly for Yamamoto's instructions.

Seeing the performance of the Riding team, Yamamoto was not angry, but rather pleased, and said without changing his expression:

"It's alright, just say it."

The members of the Riding team nodded and whispered, "Reporting to the captain, the order has been conveyed to all captains!"

Yamamoto responded, "Very good. Inform the vice-captain of the Sparrow Club to prepare for the captains' meeting in a week."

"Yes!" The Riting team members nodded emphatically, their figures flashing and disappearing from the office.

"A captain's meeting?" Aozaki Mazuki looked at Yamamoto curiously.

“That’s right, the captain’s meeting,” Yamamoto nodded. “You’ll be attending too!”

Chapter 113 Experiment

The sky gradually darkened.

Aozaki Mayuki left the First Division barracks.

With Yamamoto's permission, he no longer needed to return to the Fourth Division for hospitalization and observation, and thus gained some rare free time.

However, he still returned to the Fourth Division to inform Retsu Unohana, Yoruichi, and the others before leaving Seireitei.

Thieves and thugs mingled in the East 62nd ward of Rukongai at night. The streets were peaceful, and the starlight and moonlight illuminated the dark world.

Aozaki Mayuki stood in the cabin deep in the forest, silently observing. The rustling of the leaves in the wind reminded him of a few years ago.

About four or five years ago, it was also in the woods, but in another woodland in the distance.

Under the beautiful moonlight, a bespectacled man stood in the shadows under a tree, looking at me with a gentle smile on his face.

Aozaki Mayuki stretched out her hand toward the ground, the light of her spiritual pressure like fireflies in the night.

Ripples appeared on the ground, the wooden cabinet trembled slightly, the floorboards shifted and rearranged like building blocks, and the ground seemed to have been torn open.

Aozaki Mayuki stepped inside and walked down the long staircase to a dimly lit small room.

The room was filled with various sophisticated equipment.

The place was originally very rudimentary, and it only began to resemble a laboratory after Aozaki Mayuri looted his experimental equipment.

Press the mechanism on the wall.

The walls cracked, and dozens of wooden panels overlapped outwards, revealing the hidden collection within.

The interior of the walls was illuminated by a dim blue light, revealing a row of bottles and jars.

"The maggot's nest is a good place!"

Looking at the fruits of her labor, Aozaki Mayuki couldn't help but sigh.

The transparent bottle was filled with black jade beads, from which wisps of purple smoke rose; there were nearly a hundred beads in total.

These are the experimental materials collected by Aozaki Mayuki.

The jade bead is a container for souls, containing the souls of the Grim Reaper or those with the potential to become Grim Reapers.

More than half of them come from maggot nests.

The souls produced there are of very high quality, and the occasional disappearance of one or two will not arouse suspicion.

After all, that prison was never short of inmates who committed suicide due to mental breakdowns.

Aozaki Mayuki walked to the middle of the wall and took out the most important experimental material—

The soul of Oni Kenpachi!

His soul jade bead contains the largest fragment of the Spirit King among all the experimental materials.

Taking into account its inherent soul strength, its value can be equivalent to dozens, or even hundreds, of soul jade beads!

Aozaki Mayuki stood in front of the experimental table, operated the machine for a while, and the platform that held the soul extended out.

He held the soul of Oni Kenpachi in one hand and took out a long-sealed soul in the other.

Aozaki Mayuki had witnessed Aizen's soul-fusion process, where unrelated souls were placed into a common jewel using special filtering equipment.

Jade beads themselves have the function of storing and absorbing souls.

He tried to contain the soul directly within the same jade bead, but the result was always the jade bead shattering and the soul dissipating.

The failure of the soul fusion experiment made him realize that he was a complete novice in the field of science.

So he didn't rush into experiments. Instead, he learned scientific research techniques from three other geniuses he knew, and at the same time, he summarized the various mistakes he had made in his previous attempts.

Kiryu and his two companions readily accepted Aozaki Mayuki's request to learn scientific research.

He is an advisor to the Technology Development Bureau, so it's understandable that he wants to learn about scientific research.

Because the development of the Hogyoku violated ethics, Aizen was entirely self-taught, and much of the information was collected, organized, and learned by himself.

Aizen didn't seem to have much intention of hiding anything. Apart from the core data of the Hogyoku itself, he let Aozaki Mayuki browse through the rest of the research data.

Perhaps it was because he had absolute confidence in his own intelligence...

He himself had not been able to obtain any useful research results, and he did not believe that Aozaki Mayuki could catch up with him under the same conditions, let alone surpass him.

Therefore, Aozaki Mayuki is essentially following in Aizen's footsteps.

Fortunately, Aozaki Mayuki not only has a genius friend but also a genius prisoner.

There is also Kiryu Hikifune, whose research on the soul is currently unmatched by anyone.

Shingetsu concealed the true nature of his research on the Hogyoku, but he still managed to gain some insights by subtly inquiring about technical issues.

Aozaki Mayuki had always left a bad impression on them.

Aside from being amazed that this imaginative guy could come up with some good ideas, the three of them had no doubt about his true purpose.

Aozaki Mayuki benefited greatly from simply flipping through Aizen's research notes in his lab and asking Kiryu and the other two for answers to their questions.

Soon, as his studies deepened, he figured out the conditions for soul fusion.

While summarizing what she had learned, Aozaki Mayuki began to plan the next step of her experiment.

With the equipment in his current laboratory, he can barely attempt a soul fusion experiment.

After a moment's thought, he put down the soul of Gui Yancheng.

Just to be on the safe side, he took out another soul jade bead containing a fragment of the Spirit King.

Since the captain's soul was extremely rare, he decided to start his experiments with some less precious souls.

In Aozaki Mayuki's plan, the main part of the Hogyoku is still the Soul King fragment, which is the key to soul fusion.

However, these souls must be filtered through several instruments to remove the external spiritual particles mixed in, allowing the souls to return to their most essential state.

Many of these instruments were among the experimental equipment Mayuri Kurotsuchi left for Mayuki.

Before he went to prison, his main research subjects were Quincy, who were all living people.

In order to study them in Soul Society, it is necessary to turn them into dead people in the absence of a spirit particle conversion device.

Not to mention soul filtering devices, they even have devices for capturing Quincy souls.

After a Quincy dies, their soul returns to Yhwach, the progenitor of the Quincy, and this genius snatches people from Yhwach's grasp!

There were only two real challenges in the entire plan.

First, how to filter the impurities in the soul and make it pure; second, the experiment requires fragments of the Spirit King.

Both difficulties have now been resolved.

Crushing the jade bead without any fragments of the Spirit King, Aozaki Mayuki emitted purple energy from her hand, stabilizing the dissipating soul before placing it into the filtering device.

Filtering souls is a delicate task, and because he was not yet very skilled, it took Aozaki Mayuki two whole hours to complete it.

After examining the two final soul-storing vessels using a high-precision X-ray vision device...

Aozaki Mayuki discovered that both souls were damaged to varying degrees, but the extent of the damage was negligible.

Next, Aozaki Mayuki infused the two souls into the Soul Jade Bead and then quietly awaited the result.

After a short while, the jade bead emitted a faint sky-blue luster.

Aozaki Mayuki remained calm as she observed the jade bead through the instrument.

As the luster gradually fades, the surface of the jade bead begins to become uneven, and its size increases slightly.

Simply put, its shape is changing from a smooth jade stone to a lump of coal.

Chapter 114 Baoyu

It was expected that the Hogyoku would turn into a "coal ball," so Aozaki Mayuki was not disappointed at all, but rather delighted.

This shows that the experiment is progressing in the right direction!
