Then, Yamamoto controlled his own Reiatsu to meet Toshiro's.
Boom! Rumble!!
A series of violent air explosions rang out continuously, far more imposing than their previous clash of presence.
And, as Toshiro expected, Yamamoto still held a slight advantage.
'Truly worthy of being the strongest Shinigami. His Reiatsu is indeed a bit stronger than mine. To win, I can only hope my techniques surpass his...'
Toshiro thought to himself.
Considering this, Toshiro immediately decided to strike first.
"Frozen Kingdom!"
Toshiro chanted softly.
As his voice fell, an immensely powerful, seemingly all-freezing chilling intent radiated from Toshiro's body.
Then, within a radius of hundreds of kilometers, snowflakes actually began to drift down, transforming the area into a frozen kingdom in moments.
Simultaneously, Yamamoto, within this area, felt his power being greatly suppressed.
"This is..."
Yamamoto exclaimed in surprise.
"This is my [Frozen Kingdom], similar to a domain."
Toshiro explained: "Within my Frozen Kingdom, all enemies' power is greatly suppressed. Conversely, my own power is significantly amplified."
Naturally, this Frozen Kingdom was something Toshiro recently developed.
After his breakthrough, Toshiro discovered that his Reiatsu, imbued with partial divinity, could actually influence the surrounding environment.
Regardless of the original environment, under the influence of his Reiatsu, it would gradually transform into a world of ice and snow.
Moreover, in such an environment, Toshiro's own power would be greatly enhanced, while being extremely repulsive to other foreign energies.
Thus, Toshiro seized the opportunity to develop the Frozen Kingdom technique.
"Frozen Kingdom, huh? Truly impressive. However, trying to weaken my power is impossible!"
Yamamoto declared.
Then, Yamamoto lightly swung his Zanpakuto.
Boom!
A massive amount of highly condensed flames erupted from Yamamoto's Zanpakuto, enveloping his surroundings.
Although it couldn't completely negate Toshiro's Frozen Kingdom, the power of Toshiro's Frozen Kingdom also couldn't affect Yamamoto in the slightest.
Seeing this, Toshiro frowned. 'As expected, just relying on Frozen Kingdom can't weaken Genryusai-sensei's power?'
However, Toshiro soon dismissed it. 'Well, forget it. Even if I can't weaken Genryusai-sensei, it still amplifies my own power. That still increases my chances of winning against him.'
'As for whether I can win, that depends on the upcoming direct confrontation.'
Toshiro mused.
Whether weakening the opponent or strengthening oneself, ultimately, it comes down to a head-on clash.
Thinking this, Toshiro took the initiative.
Then, an ice-blue light flashed behind Toshiro, and a pair of massive ice wings appeared on his back. With a flap, he instantly soared into the air.
"Thousand Years' Ice Prison!"
Toshiro then chanted softly.
As his voice faded, the originally chaotic, dim Dangai was suddenly overcast with dark clouds from nowhere, shrouding the sky above.
Then, a pillar of ice-blue Reiatsu shot skyward, and within the dark clouds, an ice-blue void abruptly appeared.
Subsequently, the ice-blue void continuously expanded, covering the area below where Yamamoto stood and its surroundings.
Then, endless snowflakes cascaded down from the ice-blue void like an avalanche.
Below, Yamamoto, watching the snowflakes falling towards him, couldn't help but frown.
Yamamoto could sense that these seemingly beautiful snowflakes harbored a lethal threat.
Instinctively, he wanted to evade, but he stopped himself.
The moment Yamamoto prepared to move, he also sensed the ice-blue void in the clouds above him shifting accordingly.
Thus, unless he could instantly teleport hundreds of kilometers away, beyond the cloud cover, no matter how he moved, he couldn't evade.
"Can't dodge it? Fine. I don't even remember the last time I encountered something that threatened me. Let me directly crush this technique!"
Yamamoto declared solemnly.
"Zanka no Tachi, West: Zanjitsu Gokui!"
Yamamoto's immense Reiatsu instantly transformed into terrifying flames matching the 15 million-degree temperature of the sun's core. These flames then cloaked Yamamoto's body and blade.
At this moment, Yamamoto resembled a god draped in the blazing sun… powerful and seemingly invincible.
Now, the snowflakes of Toshiro's Thousand Years' Ice Prison silently vanished into nothingness as they neared Yamamoto's vicinity.
As more and more snowflakes fell, they eventually completely enveloped Yamamoto within.
However, seeing this, Toshiro felt no joy. Because the ice flowers hadn't bloomed, meaning Yamamoto was unharmed, merely buried under the snowflakes.
Boom!
Fierce flames suddenly erupted from within the snowflakes, instantly reducing the snow of Thousand Years' Ice Prison to nothingness.
Then, the unscathed Yamamoto spoke: "This technique is called Thousand Years' Ice Prison? Truly a remarkable move. But under the might of my 15 million-degree flames, it's useless."
"Genryusai-sensei is indeed formidable. This is the first time my Thousand Years' Ice Prison has failed."
Toshiro said, somewhat astonished.
When Toshiro was only Captain-level with an immature Bankai, Thousand Years' Ice Prison was his ultimate technique. As his strength continuously progressed, Thousand Years' Ice Prison's power also kept increasing.
So even now, Thousand Years' Ice Prison remained one of Toshiro's strongest ultimate moves.
Toshiro originally thought that even if Thousand Years' Ice Prison couldn't cause substantial damage to Yamamoto, it would at least freeze him for a while.
He never expected Yamamoto to emerge completely unscathed.
"If Thousand Years' Ice Prison is useless, then let's test the power of this move."
Toshiro said with a serious expression.
"Four Elements Freeze!"
After Toshiro's words, he flapped his ice wings and instantly descended towards Yamamoto below.
Then, as he closed in on Yamamoto, he thrust his sword straight forward!
