"Who dares to violate the Commander's ban in Seireitei and release their Zanpakutō's Bankai?"
Ailin's spiritual pressure soared into the sky. Almost everyone in Seireitei could feel Ailin's vast and majestic spiritual pressure.
In an instant, all the Soul Reapers in Seireitei turned their gazes towards the Kuchiki family's direction.
How could they have imagined that in less than six years since the rebellion incident where someone violated the Commander's ban, there would be another Soul Reaper violating Commander Yamamoto's ban and releasing their Zanpakutō in Seireitei.
How bold, not afraid that violating the Commander's ban repeatedly would incur Commander Yamamoto's great wrath?
"Oh? This spiritual pressure, it's Captain Ailin?"
"The location is at the Kuchiki family too, what's happening?"
The Captains guarding Seireitei immediately recognized Ailin's identity upon sensing this immense Reiatsu.
After all, over five years ago, it was Ailin who defeated the traitor Koga, saving Seireitei from a great disaster. It was just everyone's first time sensing Ailin's full power spiritual pressure.
"Oh my, I didn't expect that Captain Ailin had reached such a level."
In the 8th Division, Shunsui Kyoraku secretly took a sip of alcohol behind his vice-captain Lisa Yadōmaru’s back and sighed in surprise, "It's just strange, no one's fighting Captain Ailin, so why would he suddenly release his Zanpakutō?"
Aside from Shunsui Kyoraku, Jūshirō Ukitake in the 13th Division also raised his head in surprise.
In his childhood, Jūshirō Ukitake had suffered from a serious illness, nearly dying. As a minor noble family, the Ukitake family also knew about the Soul King being torn apart by the ancestors of the Five Great Noble Families. Hence they coincidentally found out about the whereabouts of the fragmentation that became "Mimihagi" after the Soul King's right arm turned into the "Demi-God of the Right Arm". In order to save Jūshirō Ukitake, his parents secretly brought him before "Mimihagi".
Afterwards, Jūshirō Ukitake's lungs were offered as a sacrifice and he became the "Right Arm of the Soul King", allowing him to survive.
Through the "Right Arm of the Soul King", Jūshirō Ukitake could obtain some visions of the future seen by the Soul King. This ability was called "Divine Possession" by Jūshirō Ukitake.
However, at this moment, Jūshirō Ukitake also had some doubts on his face. When Seireitei was facing its greatest crisis, Jūshirō did not see Ailin's figure in his visions.
At that time, he assumed it was because Ailin's strength was insufficient and had stepped down from his position as the 6th Division Captain after Byakuya Kuchiki grew up.
But from Ailin's erupting spiritual pressure right now, although Ailin's spiritual pressure might be slightly weaker compared to himself and Shunsui Kyōraku, it wasn't too big a gap.
How could someone so powerful be invisible during that great battle?
He would have to investigate later to see if Ailin was being punished for violating the Commander's ban this time, causing him to be absent from the battlefield. Otherwise, with Captain Ailin demonstrating such power presently, if he harbored any resentment towards Seireitei, he would become a huge threat...
"Bankai—Unlimited Blade Works!"
Accompanying Ailin's final chant, his true Bankai appeared in the Soul Reaper world for the first time. The endless barren land, fiery red sky, as well as the gigantic rotating gears acting as space partition...
Countless Zanpakutō were stabbed into the ground. The hilts of all the Zanpakutō were slightly tilted towards the Sword Hill, seemingly paying homage to the Emperor residing upon the hill.
There were also sparsely scattered Zanpakutō stabbed atop the Sword Hill. These Zanpakutō seemed to form steps, adding some layering to this tall and independent hill.
Everything demonstrated to Byakuya Kuchiki that the space he was currently in was no longer Seireitei.
Byakuya Kuchiki raised his head to look at the master of this space.
At the highest point on the hill stood a lonely figure. The crimson ceremonial kimono fluttered in the wind. Beneath the white Captain's haori he wore was not the black shihakushō, but a red holy shroud.
Byakuya Kuchiki stared blankly. The powerful spiritual pressure emanating from Uncle Ailin made him feel like even breathing was difficult. His body seemed to have gained a will of its own, resisting his control.
Byakuya Kuchiki uncontrollably swallowed a mouthful of saliva. Big beads of cold sweat rolled down his forehead. He did not understand why Uncle Ailin was using his Bankai to train him.
"This is my world..." Standing atop the hill, Ailin spread open his arms and embraced his world for the first time.
Unlimited Blade Works!
This was Ailin's biggest secret in the Soul Reaper world besides himself. According to Ailin's past thinking, this Reality Marble was absolutely not something he could reveal to others. Anyone who forced Ailin to use this move would either die or perish.
However, because of Haruko Kuchiki, Ailin would remain in Soul Society for at most another three months. Revealing some things wasn't an issue. Moreover, all he revealed was his spiritual pressure. The existence of Unlimited Blade Works was only known by Byakuya.
Of course, Ailin only wanted to use this space to train Byakuya. He did not plan on explaining anything regarding his Reality Marble's abilities to Byakuya.
"Byakuya, do you know of my Zanpakutō's abilities?"
After venting his emotions for a bit, Ailin lowered his arms and turned to look at Byakuya Kuchiki below the hill.
"Mm. I heard from grandfather that Uncle's Zanpakutō ability is sword creation."
"Correct. My Zanpakutō's ability is crafting swords. This space is where I forge swords. It is also where I store the swords I've crafted. All the swords within this space were made by me. I have absolute control over the swords I've forged." After speaking, Ailin snapped his fingers.
In an instant, all the Zanpakutō in the space aside from those on the hill floated up from the ground. They circled in the air in neat rows, surrounding Byakuya Kuchiki in the middle.
This scene was somewhat similar to Byakuya's future move "Senbonzakura Kageyoshi".
Even Byakuya Kuchiki felt some unease being surrounded by so many swords. His eyes darted left and right.
The next moment, Ailin's figure flickered as he appeared inside the arena formed from thousands of swords after descending from the Sword Hill.
"Byakuya, I've told you before that I hope you don't turn this 'surprise' I have for training you into 'fright' too quickly. I only have three months to train you. To allow you to gain the most from it, my training for you only has one item— Battle!"
Ailin reached out and one of the Zanpakutō comprising the arena directly flew over into his hand from its position.
"Here, I will keep my spiritual pressure, strength and speed all at a similar level to yours... Draw your sword, Byakuya!"
