Ultimate Evolution, Final Evolution (Continued)

Shortly after his birth, he had been struggling in the Rukongai, killing countless enemies and even establishing the Gotei 13, a group of assassins.

Over the years, he had dealt with many opponents, but he had never encountered one like Aizen who was impossible to kill.

His extensive combat experience told him that he absolutely had to turn the man in front of him to ashes in one strike.

Otherwise, if this continues, it could very likely lead to even more serious consequences.

He rushed to within a meter of Aizen, and stomped his right foot so hard that the entire ground shattered under Riden weight.

The intense, tangible flames scorched Aizen's skin.

Those eyes, filled with absolute killing intent, pierced Aizen's nerves.

But Aizen did not back down or run away. Instead, he also raised his Zanpakuto, ready to clash head-on with Yamamoto.

At such close range, the Zanjitsu Gokui, which had once killed Aizen, was no longer able to break through Aizen's skin, which had now evolved to the third stage.

Genryūsai Shigekuni Yamamoto unleashed a powerful and heavy slash.

Although Aizen had no intention of running away, he still used his Zanpakuto, Kyōka Suigetsu, to block the Zanka no Tachi at an angle, thus deflecting its power.

The moment the Kyōka Suigetsu touched the blade, a tiny nick appeared on the blade, and a chunk of flesh abruptly disappeared from the right arm.

But that's all.

Both the nicks in the Kyōka Suigetsu blade and the wounds on the arm were completely healed in an instant.

This terrifying regenerative power far surpasses the regenerative abilities possessed by the Arrancar.

Genryūsai Shigekuni Yamamoto's eyes narrowed, and he let the sword smash into the Riden.

The ground instantly turned into charcoal, spreading in all directions, and even the sky looked as if it had been scorched.

A foul odor instantly filled the air, and the space within a radius of several kilometers underwent a dramatic change.

The sky turned gray, filled with dust particles, and the ground was scorched black, as if it had been ravaged by fire for countless years.

Extremely hot lava erupts from those cracks from time to time.

Seeing this, Aizen laughed and said, "Are you planning to burn me to ashes with endless flames?"

He guessed why Genryūsai Shigekuni Yamamoto used such a domain-like technique.

However, he wore a smile on his face, showing no fear whatsoever. "Interesting, let's give it a try."

As he finished speaking, a skeletal hand suddenly emerged from the cracks in the scorched earth.

The hand was not white bone, but rather emitted a blood-red light, like molten steel.

He grabbed the scorched ground beside him and suddenly leaped out of the crack.

Snap! Another skeleton like this emerged from another crack.

One, two, a hundred, a thousand.

In an instant, the entire area was filled with these skeletons emerging from the ground, as if demons from Hell had been released into the wild.

"Zanka no Tachi, South, Kaka Jūmanokushi Daisōjin"

Genryūsai Shigekuni Yamamoto raised his sword with one hand, his eyes blazing with murderous intent as he stared at Aizen: "I have awakened the ashes of those who died by my blade; they will transform into endless flames until they burn you to ashes."

The charred skeletons, who had been wandering aimlessly, suddenly lunged at Aizen with bared teeth and claws. They moved so fast that Aizen didn't even have time to react before he found himself being grabbed by the skeletons.

The lower leg that was being held was now emitting black smoke, and a burning pain came through the skin.

Clearly, the temperature of these charred skeletons had risen to a level far beyond what the Zanjitsu Gokui could match.

Even Aizen couldn't help but marvel at how Genryūsai Shigekuni Yamamoto's strength had still managed to improve to a higher level even now.

He casually swung his Zanpakuto at the charred skeletons, and to his surprise, he easily shredded them into pieces.

But it was all in vain; the skull, chopped into pieces, instantly regenerated and continued its advance towards Aizen.

Not long after, a giant sphere made up of charred skulls formed, with Aizen encased at its center.

"Captain-Commander Yamamoto, you're starting to bother me. How about I put aside the matter of Riden and help you deal with Aizen?" Tokoyo Misao, looking up.

In fact, he wouldn't mind eliminating Aizen at this time.

Genryūsai Shigekuni Yamamoto snorted coldly, "Captain Tokoyo, you just continue doing what you're supposed to do. My battle is none of your business."

"Are you really not letting me get involved? You might die." Tokoyo Misao wasn't joking, nor was he intentionally cursing or looking down on Genryūsai Shigekuni Yamamoto.

Even disregarding his past memories, Aizen will evolve again and eventually become an immortal being.

Through the charred skulls, Eternal Eyes could see that Aizen's Spirit Ribbon was beginning to disappear.

This does not mean he is about to die, but rather that he is getting closer to breaking through and becoming Transcendent.

In the end, Soul Reaper Shigekuni Yamamoto-Genryūsai, will only face defeat.

"If I die here, it will only prove that this is all I am capable of, nothing more." Genryūsai Shigekuni Yamamoto was not angry when he heard Tokoyo Misao's words, but said in a deep voice.

"This also proves that future eras will no longer need this old man."

He has always maintained the balance of the Three Worlds with unparalleled power.

If Aizen were to truly kill him, it would prove that he could no longer support the Three Worlds.

So from now on, we can leave it to those who are capable of supporting us.

He has worked hard for over a thousand years, and it's time for him to retire.

The premise is that Aizen truly has the ability to kill him.

I don't know how much time passed; maybe a minute, maybe ten minutes.

The enormous sphere, encased in charred skulls, had skulls that were still trying to pry and push their way inside.

But at that very moment, everything suddenly stopped.

Then a purple power burst forth from within.

This purple hue is quite peculiar and profound.

In the instant it appeared, it shattered this Hell domain.

Aizen's figure reappeared, and this time his appearance had changed drastically.

Its hair grew longer, wings appeared on its back, and Hollow Hole appeared on its chest. The Hōgyoku lay quietly in the center.

Compared to the second form, where the body is completely enveloped like a larva, this state has a feeling of emerging as a butterfly, achieving an evolution at the level of life.

He raised his right hand, smiled, and said, "Thank you, Shigekuni Yamamoto-Genryūsai."

Because of your power, I have finally broken through the realm of Soul Reaper.

"Look, the Hōgyoku has determined that I no longer need my Zanpakuto; Kyōka Suigetsu has already merged into my body."

This time, Genryūsai Shigekuni Yamamoto's brow furrowed even more deeply.

He took a deep breath, gathering his strength.

Tokoyo Misao was also carefully observing Aizen's current situation.

In his Eternal Eyes, the red color representing the Soul Reaper still remains. If one really had to use a stage to describe Aizen now, it would be most appropriate to call him Half-Step Transcendent.

Furthermore, the fact that it fused with the Zanpakuto also made Tokoyo Misao frown.

In fact, he had thought before that the formation of Zanpakuto itself was a process of nurturing it by infusing it with his own soul.

The Arrancar of Resurrección involves Zanpakuto back into the user, allowing it to revert to its original form.

Could Soul Reaper be the same way?

Only after Zanpakuto back into oneself does it reach its true form.

"You seem a little confused, Brother Misao," Aizen said. "Although I don't know what you're confused about, my path has already been achieved. Soul breakthrough is the path of evolution, not the physical evolution you chose."

Tokoyo Misao gently shook his head and replied, "I did not choose physical evolution, but merely made the body a vessel for the soul, evolving together."

As for you, your current state hasn't reached a complete breakthrough yet, so don't rush to refute me, because you'll soon find out."

Aizen shifted his gaze from Tokoyo Misao to Genryūsai Shigekuni Yamamoto, whose chest was slowly rising and falling, still gathering his strength.

"I see. Do you still think I could be killed by Genryūsai Shigekuni Yamamoto at this point?"

Then I can only tell you, Brother Misao, the information you received Tosesato has probably led you to make the wrong judgment.

Aizen was extremely confident. At this moment, he could feel that he had arrived in another dimension, and it was impossible for Genryūsai Shigekuni Yamamoto, Soul Reaper contend with him.

He stood there arrogantly, waiting for the other party to build up their momentum.

"What an arrogant brat!" Genryūsai Shigekuni Yamamoto exhaled slowly, speaking in a deep voice.

The next instant, flames erupted from his body, and he swung his sword from the spot.

"In the north, the Tenchi Kaijin!"

This strike Aizen.

But his body gradually turned into black ashes as the blade slid along.

By the time Genryūsai Shigekuni Yamamoto swung his sword towards the sky, Aizen had already vanished.

After slashing the Zanpakuto, Genryūsai Shigekuni Yamamoto Zanpakuto into the ground to steady himself and coughed lightly a few times.

At this moment, the Zanka no Tachi had returned to its original state, and he had released his Bankai.

That last strike was his final, desperate attack, a blow that risked his very soul.

Even when he was young and strong, he could only manage one strike.

He took another deep breath, braced his hands on the Zanpakuto, straightened his body, and stared blankly into the empty space before him, saying in a deep voice, "How ugly!"

After saying that, he murmured softly, "From now on, I'm leaving it to you."

A clear and distant exhale echoed in the empty space.

The next moment, a Hollow appeared... No, although he looked like a Hollow and his power leaned towards Hollow, he wasn't. He was Aizen, who had evolved once again.

At this moment, his form changed drastically again. His hair had grown long enough to touch the ground, there were three Hollow Holes in his chest, his entire face was covered by a black mask, and he had three pairs of fleshy wings on his back.

It has eyes on its wings, and the tips of its wings are illusory masks.

Even his tailbone had three long tails growing out of it, making him look exactly like a ghost.

The moment he straightened up, the masks on those fleshy wings suddenly opened and bit down hard.

Genryūsai Shigekuni Yamamoto's body was gnawed off at the waist out of thin air.

He coughed up blood, fell to his side, and landed with a thud on the floor of the Riden, closing his eyes.

At the same time, Tokoyo Misao finally found the thing in the Riden that had been drawing spiritual energy from the Soul King Palace.

That was a black seed, and the fundamental reason why Ichibē Hyōsube could keep reviving.

As long as this seed Riden, it will continuously draw upon the power of the Soul King from the Soul King Palace, thus making it immortal.

This black seed, like a parasite, worked in conjunction with Riden to parasitize the Soul King.

Tokoyo Misao raised his right hand. "Wait a moment, it'll be over soon."

Although Aizen's evolved form at this time was no different from a Hollow, and looked terrifying, he possessed complete rationality.

He stood still, not launching any attack on Tokoyo Misao, and waited quietly.

Tokoyo Misao's palm, pressed against the ground, revealed a section of a red-wrapped blade tip. He slashed into the Riden, aiming for the black seed at its center.

With a crisp "plop," the black seed was severed.

This Riden no longer draws power from the Soul King Palace.

Tokoyo Misao stood up, clapped his hands, took two steps, came to the body of Shigekuni Yamamoto-Genryūsai, and extended his fingertip.

Spiritual energy threads emerged from his fingertips, rapidly reassembling Genryūsai Shigekuni Yamamoto.

Then he bent down, picked him up, walked to the side of the Riden, released his hands, and let Genryūsai Shigekuni Yamamoto's body fall towards Soul Society.

"Ah, I almost forgot." Tokoyo Misao turned back and grabbed Ryūjin Jakka: "I'll have to throw you down too."

That was his original plan, but the moment he gripped the knife tightly, the blade began to vibrate and emit a soft buzzing sound.

Tokoyo Misao was taken aback.

Logically speaking, if Soul Reaper dies, the Zanpakuto nurtured from his soul should also perish.

But there are always exceptions.
