Chapter 638 - 638 Breaking The Cocoon to Rebirth!

Neither Aizen, the 'victim', nor Unohana, who was preparing to 'sacrifice herself heroically', had clearly expected this sudden turn of events. Both looked utterly shocked.

Aizen looked down at the blade piercing his heart and said in disbelief: "Gin... I didn't expect you to..."

"The only way to escape Kyoka Suigetsu is to touch the blade before its complete hypnosis ability is activated..."

Gin turned to look at Aizen: "I don't know how many years I spent trying to find out this information..."

"But it was all worth it. The Gotei 13 thought they could kill you, Captain Aizen, with their own strength. But in the end, neither Yamamoto Genryusai nor Hitsugaya Toshiro succeeded. Now it seems that only I... am able to kill you, Captain Aizen!"

Squelch—!

Gin's extended Zanpakuto blade shortened again.

Sclick!

After Gin's Zanpakuto was withdrawn, blood gushed from Aizen's chest like a fountain.

"..."

Aizen grunted in pain and quickly covered the wound on his chest.

Drip, drip, drip...

Blood flowed through Aizen's fingers, showing no sign of stopping.

"I knew it long ago... I knew your purpose long ago... Yet I still chose to keep you by my side... Because I was very interested in how you would take my life. However..."

"...What a pity, Gin. You think an attack of this level can kill me?"

As he spoke, Aizen looked somewhat disappointedly at Gin: "In my previous battle with Toshiro-kun, I was stabbed in vital points more than once by his Zanpakuto, yet I am still alive and well..."

"To the current me, even the heart, a deadly vital point for ordinary people, can no longer cause me much harm."

But upon hearing Aizen's words, Gin remained calm: "I never thought that stabbing your heart would kill you."

As he spoke, Gin raised his Zanpakuto, which was only slightly longer than a dagger, and asked Aizen: "Do you see this? Here..."

Gin pointed to a diamond-shaped hole in the middle of the blade. "There's a gap. Just now... I left it inside your body, Captain Aizen."

Having said that, Gin pointed his left finger at Aizen.

"What?" Aizen's heart tightened.

"I told you about my Bankai's ability before, didn't I? But... sorry, Captain Aizen, I lied at the time. My Zanpakuto's Bankai cannot extend to 13 kilometers, nor can its extension and contraction speed reach 500 times the speed of sound. However..."

"—In an instant, the blade turns to dust, and the inside of the blade releases a deadly poison that can dissolve cells," Gin said with a dangerous smile.

Hearing Gin's explanation, Aizen instantly realized something, his expression turning very grim.

"It seems you understand. Yes, after piercing your heart just now, when I withdrew the blade... a piece of dust containing deadly poison was left inside your heart, Captain Aizen," Gin explained.

Hearing Gin's explanation, Aizen couldn't help but instinctively cover the wound on his chest, then said with a grim expression: "Gin..."

"If you have time to talk, you'd better spend it figuring out how to survive. But... well, even if you hurry, a dying person will eventually perish."

Then, Gin walked up to Aizen, placing his left hand on Aizen's chest: "Kill, Kamishini no Yari!"

As his voice fell, the deadly poison capable of dissolving cells instantly erupted within Aizen's body.

"Gin... you bastard!!!!"

"To have your chest hollowed out and die… that is what you wished for, isn't it!" Gin said in a deep voice.

Boom!

As Gin's voice fell, a large hole was instantly dissolved in Aizen's chest, nearly splitting his entire body in two.

At the center of the large hole was the Hogyoku that had been fused with Aizen.

Seeing this, Gin reached out to take the Hogyoku.

Aizen instinctively reached out to stop Gin.

Clap!

Gin ruthlessly slapped Aizen's hand away and seized the Hogyoku in his grasp.

Then Gin's figure flashed, leaving Aizen's side and appearing on a nearby street corner.

Bang!

Aizen's body fell weakly to the ground, his arm pointing towards Gin on the street corner: "Gin... ugh!!!"

The intense pain of his cells being dissolved caused even Aizen to scream.

Hum, hum, hum—!

Waves of violent and chaotic Reiatsu emanated from Aizen's body. Due to the immense pain and damage caused by the gradual dissolution of his cells, the extremely powerful Reiatsu within Aizen began to lose control, seeming as if it might explode at any moment.

Seeing this, Unohana on the other side, like Gin, quickly picked up the unconscious Toshiro and fled to a safe distance.

"Aarrggghhhhh—!!!"

Watching his own body being dissolved by the deadly poison, a huge sense of fear rose in Aizen's heart.

Then, a special power suddenly erupted from deep within Aizen's body. Under the influence of this special power, the dissolution of Aizen's body cells stopped.

The granulation at the edge of the large hole dissolved in his body turned into purple crystalline substance.

Then, the purple crystalline granulation at the edge of the large hole wriggled, and the large hole dissolved in Aizen's body by the deadly poison began to heal.

…

On the street corner.

Drip, drip, drip...

Drops of blood fell from Gin's arm.

This was an injury caused when Gin seized the Hogyoku and slapped away Aizen's obstructing right hand, being scratched by him in an instant.

"Huff, huff, huff..."

Gin was sweating profusely, breathing rapidly as he looked at the Hogyoku tightly grasped in his hand. Although the battle with Aizen had been instantaneous, that instant had cost Gin too much thought and scheming. If the slightest thing had gone wrong, Gin's plan would have completely failed.

"Huff… Huff... It's over... With this, everything ends..." Gin looked at the Hogyoku in his hand with a complex expression.

As soon as Gin finished speaking, an immensely powerful Reiatsu, as if surpassing the Shinigami limit, suddenly erupted from not far away.

"What?!" Gin looked in shock towards where Aizen was.

A powerful purple Reiatsu Pillar shot into the sky from where Aizen was, piercing the sky.

Finally, when the purple Reiatsu Pillar dissipated, Aizen's figure appeared again.

Aizen stood proudly in the void, his appearance changed once more. His eyebrows were gone, a slit resembling an eye appeared on his forehead, and three pairs of huge butterfly wings grew from his back, like a butterfly breaking free from its cocoon to rebirth.

Hogyoku Fusion Fourth State!

At this moment, Aizen had broken the Shinigami limit and evolved to a higher dimension!!
