Death: This Death is a bit unorthodox.

For a moment, he exuded an unparalleled sharpness, like a sword about to be drawn, making people afraid to look directly at him.

Standing in front of the mirror, Aizen Sousuke carefully examined his reflection.

At that moment, he did indeed look like a gentle, kind, and approachable old man.

However, only a few people know what kind of scheming and cunning lies behind this mask.

Kuchiki Hibiki pushed open the door and stepped into the room, then paused in surprise.

Aizen Sousuke stood there straight, a bright smile on his face.

Normally, this man always had a gentle smile on his lips, but that was just a disguise he used to cover up his true emotions.

He rarely showed such a genuine smile.

Such a situation is truly rare, and Kuki-no-Kawa couldn't help but feel puzzled.

That smile wasn't exactly ugly, but it was disgusting, and it was far more unsightly than the usual fake smile!

What good thing happened to this man that made him so excited that he couldn't even control his facial expressions?

At that moment, he seemed to have become a child, gazing at the toy he had always dreamed of, his face full of longing and anticipation.

For a moment, Kuki-no-Kawa didn't know how to react, so he silently led the bull-headed Wastodd into the house.

After entering, he carefully closed the door and checked the lock to make sure no one would suddenly break in.

Then, Kuchiki Hibiki silently stood behind the man, slowly taking off his blood-stained black robe with one hand, while tightly clutching his injured shoulder with the other.

It's only a hundred miles from Tsunayo's house to the laboratory, but in order to avoid the ubiquitous surveillance of the Gotei 13's stationed area, he had to take a detour, specifically traveling from the remote suburbs all the way here.

At this moment, the wound on his shoulder had begun to scab over, but it would tear open again with the slightest movement, and a small stream of bright red blood would slowly flow down his arm.

He took out the first-aid kit from the metal container, saying that he could only rely on these simple medical tools to treat his injuries for the time being.

He was a true man who had been through the baptism of war; he could endure this minor physical pain and had suffered much more serious injuries. He finished bandaging the wound in less than a minute.

Kyoga Kuchiki changed into a clean Shinigami outfit, tied the Camellia armband representing the Sixth Division to his shoulders, and wrapped a red Kazekasa veil around his neck, so that nothing seemed amiss.

He stood in front of the mirror, carefully examining himself. His appearance seemed normal, but his face was slightly pale and lacked a rosy hue.

Without hesitation, he threw all his blood-stained clothes into the incinerator.

Their experiments are related to biology, making such facilities specifically designed for waste disposal essential.

After doing all this, he conducted a meticulous inspection of the entire laboratory to ensure that not a single clue was left unchecked.

He knew he must not let anyone discover anything, because Kuchiki Hibiki was a completely different person after leaving the laboratory.

An existence completely unrelated to Aizen Sousuke.

He is a model son-in-law who listens to his father-in-law's teachings, loves to study kendo with his close friends, cherishes his wife in life, and never has affairs.

Sometimes, even Hikari Kuchiki himself would sigh that he had disguised his true self so perfectly that he was no longer the person he used to be.

However, it was precisely this image that won the hearts of his father-in-law and wife.

If they were to understand their own actions, they would probably never be able to love themselves again, and might even see themselves as monsters.

I felt really good when I wiped out the Tsunayo family!

No one likes monsters, and Kuchiki Kyoga knew this perfectly well. He himself didn't like them either, and he didn't harbor any resentment.

He chose to hide his true self and continue to conceal his cruel side.

Because Kuchiki Hibiki doesn't want to lose them, that's all.

Aizen Sousuke wrapped the coal ball in a strange metallic membrane, and as his spiritual pressure flashed, the metallic ball became transparent.

"How were the results of the experiment? Judging from your expression, they don't seem very good."

"Yes, it's the same as always. Those with weak spiritual pressure collapse, while those with strong spiritual pressure turn into Hollows." Kuchiki Kyoga nodded. "This experiment has undoubtedly failed... You don't seem surprised at all?"

"We've already done so many experiments, shouldn't we have been prepared?"

"So, does this experiment have to be terminated again?" Kuchiki Hibiki asked, frowning.

"No, I've already found a solution." Aizen's lips curled up slightly, revealing a confident smile.

His eyes were firm and bright, as if he had already seen through everything.

This statement implies that the experiment will not stop there, and outdated technologies will be discarded.

Upon hearing this, Kuchiki Hibiki's eyes widened suddenly, a hint of surprise and doubt flashing in them, but he quickly regained his composure.

He nodded, indicating his understanding: "Yes, I understand."

Kuchiki Hibiki had no doubt about the intelligence of the man before him.

This man has created many amazing and unimaginable achievements.

Although previous Hollowfication experiments may not have been entirely successful, being able to transform a Shinigami into a Hollow and greatly enhance its power is already an extraordinary achievement.

If this man is allowed to continue his research, he might actually realize his dream someday.

"You're looking forward to it too, aren't you?" Aizen suddenly turned to look at Kuchiki Kyouga and said softly.

"Expecting?" Kuchiki Kyoga was taken aback, wondering to himself what he was expecting.

Aizen gently shook his head.

The space behind him seemed to be torn apart by a pair of invisible hands, revealing a huge oval-shaped black hole.

The cave was filled with thick fog, giving it a mysterious and unpredictable feel.

Black cavity!

This is a void spatial passage, equivalent to the Grim Reaper's portal to another dimension!

What emerged was not an illusion, but the voice of Tosen Kaname!

Without even glancing at Kuchiki Heikawa, he lifted the transparent metal sphere and stepped into the dark cavity.

"Aizen has even figured out the Hollow's black cavity!" Kuchiki Kyoga exclaimed in surprise.

Chapter 224 Voluntary

"As expected of your twisted sense of humor."

Yan Luojing gently smoothed the strands of hair behind her ear, then slowly raised her head, her eyes clear and bright, as captivating as autumn water.

"From what you're saying, do you know me very well?" Aozaki Mayuki blinked, a hint of doubt on her face.

"Yes, I understand. I am your Zanpakuto now. I get along quite well with those girls, and they like you quite a bit."

Yan Luojing sighed softly, her voice as light as a gentle breeze.

"Someone's coming."

"Don't worry, she's very gentle." Aozaki Mayuki playfully stuck out her tongue.

"You don't need to worry about me too much, I'm perfectly fine..."

"To be honest, I never do business at a loss. By letting you stay here, it's like you're renting my place."

"Logically speaking, you should be paying me rent."

"It's too early to say all this now," Yan Luojingdian chuckled. "Besides, you haven't really taken this matter seriously."

"Hmm... I see. So you want me to give you my true heart?" Aozaki Mayuki hesitated for a moment, her fingers gently gliding across the water's surface, creating ripples. "You want to establish a spiritual connection with me?"

Yanluo Jingdian lowered her head silently, leaning over Aozaki Mayuki. She didn't speak, but simply reached out her slender hand and gently stroked the face full of doubt.

"Goodbye," Yanluo Jingdian said softly.

"Goodbye," Aozaki Mayuki replied, her gaze fixed on the woman who was gradually becoming blurry and illusory before her until she disappeared.

Just then, a figure gently pushed open the door and slowly stepped into the room.

She lowered her head, gazing at the steaming pool, gently smoothing her cascading hair, which was incredibly beautiful. Then, with graceful movements, she untied the sash around her waist, removed her yukata, and stepped towards the bath.

Aozaki Mayuki quietly opened his arms, waiting for the woman who was walking towards him.

Finally, she arrived in front of Aozaki Mayuki and gracefully sat down in the warm pool.

In the misty air, the two were so close that they could clearly feel each other's breath.

Retsu Unohana's bright eyes were charming and alluring, seemingly blending into the surrounding transparent pool water, making her appear even more gentle.

She looked up at Aozaki Mayuki, whose already gentle and graceful face was now made even more beautiful by a faint blush.

The rain outside intensified, with torrential downpours pounding against the wooden windows and splashing up countless tiny droplets.

The torrential rain lashed violently against the ground, splashing up sprays of water, and the world was instantly shrouded in a misty rain.

“You look very happy.” Retsu Unohana leaned against Mayuki Aozaki, her eyes gazing up at the ceiling. The misty bathroom made her feel as if she were in a fairyland. “It seems things are going very well.”

“Very smoothly.” Aozaki Mayuki adjusted her posture, letting Unohana Retsu lean on her shoulder to make her more comfortable. “The experiment was a success. I personally witnessed those old guys turn into crazed beasts.”

"A wild beast?" Unohana Retsu frowned.

She is a master of the highest level of skill; turning into a beast is not the desired outcome.

“This is only the first step in breaking the boundary between Hollows and Shinigami.” Aozaki Mayuki was silent for a moment. “After breaking the boundary, you still have to overcome the Hollow within yourself before you can control this power.”

Unohana Retsu rolled her eyes: "You knew how to become intangible from the beginning, didn't you?"

Aozaki Mayuki smiled. "Hey... I certainly have the theoretical foundation, but practical experience is just as important! Those old guys from Tsunayoshiro died a very fitting death."

Unohana Retsu leaned against the man's chest, looking at the torrential rain outside, and sighed:

“I know about your feud with the Tsunayo family… but I never expected you would actually take action against them. After all, they are one of the five great noble families that rule the Seireitei.”

The rain pattered down, like a melodious piano piece, but Aozaki Mayuki did not respond. Unohana Retsu was also speechless, and the two remained in a silent stalemate.

“Today…you’ve been with me the whole time,” Retsu Unohana suddenly broke the silence.

"Retsu is so good to me!" Aozaki Mayuki scratched her head and smiled slightly. "In that case, I can't let Retsu down."

"The virtualization experiment definitely needs to be accelerated. Let's continue the experiment tomorrow. I just happened to find two volunteers who are willing to participate in the experiment."

Since fusing with the Hogyoku, Aozaki Mayuki has been patiently waiting for his evolution, but because he cannot feel intense fear, his evolution speed is relatively slow.

However, Aozaki Mayuki does not intend to use fear to drive his own evolution.

Aizen's monstrous fusion state made him feel that it was not a successful evolution at all.
