Training Bankai (1)
After that in-depth conversation at the Visored's base, with the help of Shinji Hirako and others, Liu Ziyun finally obtained the opportunity to train in Bankai World of the Living this human Base far away from Soul Society and Aizen's eyes and ears.
In the following days, he did not rush to begin cultivation, but instead chose another approach—to completely relax and immerse himself in the rhythm of World of the Living life.
During the day, he would wander alone through the streets of Karakura Town, like an ordinary tourist, experiencing this world that was so different from Soul Society. He would buy snacks at convenience stores, sit on park benches watching children play, and order a cup of coffee at a café, sitting quietly for an afternoon.
This seemingly leisurely behavior is actually his way of adjusting his state. Bankai training is different from Shikai; it is the release of the deepest power of the Zanpakuto, a complete resonance between the Soul Reaper and the Zanpakuto's soul. In this process, any distracting thoughts, any hesitation, or any unstable emotions can lead to failure or even bring unpredictable dangers.
Liu Ziyun needs to achieve a state of absolute tranquility and peace in his mind.
Meanwhile, Kisuke Urahara was also working tirelessly. As the former director of the Technology Development Bureau, he possessed an understanding of Reishi technology and Barrier construction far beyond that of ordinary people. Deep underground in the Visored's base, he began constructing an "Absolute Isolation Space" specifically for Liu Ziyun Bankai.
The requirements for this space are extremely high—it must not only be able to completely isolate internal Reiatsu fluctuations to prevent energy leakage during cultivation from being detected by certain beings in the Soul Society or the World of the Living; it must also be sturdy enough to withstand collisions of power at the Captain-level or even higher; more importantly, the internal environment of the space must be stable and cannot fluctuate due to external interference.
Kisuke Urahara used almost all of his reserves and knowledge. He used precious materials brought from Soul Society, combined them with the most advanced technology in the World of the Living, and even incorporated some fringe technologies from "Hōgyoku" research that only he had mastered.
Three days later, when Liu Ziyun in the World of the Living,"Kisuke Urahara had finally completed the project.
"Mr. Liu, the space is ready." Kisuke Urahara stood at the entrance of the newly built training room, his face unusually serious. "However, I must remind you—although this space is theoretically capable of withstanding the power of Captain-level, if your power exceeds your expectations by too much, there is still a risk of it collapsing. Therefore... please be sure to control your power."
Liu Ziyun nodded. "I understand. Thank you, Manager Urahara."
He didn't say much, but took a deep breath and stepped into the newly built Cultivation Space.
The Cultivation Space is a huge spherical space, about one hundred meters in diameter. The walls are made of a special Reishi Alloy, and the surface is engraved with dense Kidō Runes. These Runes shimmer with a faint silver light, forming a complex, multi-layered protective network. There is no light source inside the space, but the walls themselves emit a soft glow, illuminating the entire space clearly.
As Liu Ziyun entered, the heavy metal door closed silently behind him. He could feel that the entire space was completely cut off from the outside world—not only physically isolated, but also absolutely shielded at the Reishi level. In this space, no matter what happened, no information would leak to the outside world.
At the edge of the space, Kisuke Urahara, Yoruichi Shihōin, Tessai Tsukabishi, and all the members of the Visored were observing the situation inside through a special observation window. This window was one-way, allowing observation from the outside but not from the inside, ensuring that it would not cause any interference to the cultivators.
Liu Ziyun stood in the center of the space, looked around, and then slowly drew his Zanpakuto from his waist.
The blade shimmered with a dark red and gold hue under the soft light, a state achieved through the Complete Fusion of Life-Taker and Tulu. He could feel the blade trembling slightly, as if it too was anticipating the trials to come.
"Begin, Life-Taker, Tulu."
Liu Ziyun's voice echoed in the empty space.
As soon as he finished speaking, a strange whirlwind suddenly swirled around the Zanpakuto. The wind was not a real airflow, but an energy storm composed of pure Reishi. The storm spun and condensed in front of Liu Ziyun, eventually transforming into two human figures.
The figure on the left is tall and slender, wearing a platinum robe, with long hair like a waterfall, and a gentle yet holy face—that is Life-Taker. The figure on the right is sharp and fierce, wearing dark red armor, with short hair like thorns, and eyes as sharp as knives—that is Tulu.
The two sword spirits materialized completely, standing in front of Liu Ziyun, each conjuring Zanpakuto identical to the one in Liu Ziyun's hand.
"Ziyun, now that you're ready, let's begin." Life-Taker voice, though gentle and calm, carried an undeniable authority.
Tulu didn't speak, but gripped his knife tightly, his sharp eyes fixed on Liu Ziyun, as if searching for any possible flaw.
Liu Ziyun a deep breath, adjusting his breathing and Reiatsu. He could feel that this training was different from any of the previous ones—it was not a simple battle, nor a test of strength, but a true trial concerning the essence of existence.
"So..."
The three spoke almost simultaneously, their Release Phrase echoing and overlapping in the space:
" To Existence Is to Change Fate, to Life-Taker!"
"Killing is just an impromptu game, Tulu!"
The moment the words fell, the Reiatsu of the three erupted simultaneously. Platinum and dark red light intertwined, forming a dazzling pillar of light that shot straight to the top of the space. The Kidō Runes on the walls flickered violently, beginning to absorb and disperse this massive energy with all their might.
The battle began the next second.
Liu Ziyun the first attack. He didn't use any fancy techniques, just the simplest and most direct straight slash. But the power contained in this slash made the air in the space groan in pain.
Life-Taker and Tulu came simultaneously. Unlike Liu Ziyun, who fought individually, they formed a perfect team—one focused on attack, the other on defense; one provided cover, the other counterattacked. Their coordination was so seamless, as if they were the left and right hands of the same person, without any flaws.
Liu Ziyun had no choice but to go all out. He used all the skills he had mastered— his Hakuda, his Shunpo, his Zanjutsu, and his Kidō —to the fullest extent. His figure flickered in the space, leaving afterimages with every movement; his blade drew complex trajectories in the air, tearing through the air with every swing; his Kidō were precise and powerful, causing the protective Runes in the space to flicker violently with each release.
Even so, he could only barely withstand the combined attack of the Life-Taker and the Tulu. The two men's coordination was so perfect that it was almost flawless.
Those watching the battle from outside the space through the observation windows were all stunned.
"That annoying bald guy..." Hiyori Sarugaki muttered to herself, her voice filled with disbelief, "How can he be so strong? And his Zanpakuto... is amazing too."
Shinji Hirako stared intently at the battle scene, his expression unusually serious. "So he's Two-Sword Style... and these two swords can even materialize separately, forming independent combat units. It seems that when he fought us, he not only didn't use his full strength, but he probably didn't even use half of his power."
As the Fifth Division Captain, Shinji Hirako possessed exceptional insight. He could clearly see that the strength Liu Ziyun was currently displaying was on a completely different level compared to when they fought before. If Liu Ziyun had used such power back then, they probably wouldn't have lasted even a minute.
Kisuke Urahara pushed up his hat brim, his eyes in the shadows gleaming with thoughtful intent. "They don't seem to... have given it their all yet."
"What?" Kensei Muguruma turned to look at him. "Even after all this, you still haven't tried your best?"
"Look at Mr. Liu's breathing," Kisuke Urahara pointed to Liu Ziyun in the image. "Although the battle is intense, his breathing remains steady, and his Reiatsu flow is not erratic. This indicates that he is still controlling his power and has not fully released it. As for those two sword spirits... although their coordination is perfect, the rhythm and force of their attacks seem to be holding back."
These words caused everyone to gasp in shock.
If even this level of fighting is just a "test," what will it be like when both sides unleash their full power?
Just as everyone was in shock, the battle inside the space took a turn.
After a violent collision, the three of them jumped backward simultaneously, creating distance between them.
