"Ah... uh..."
While Toshiro and Aizen were fighting fiercely, Phoenix on the other side, who had been blasted and bruised by Toshiro's #88 Hado earlier, had already regenerated under his super-speed regeneration ability and was once again charging towards Toshiro as he fought Aizen.
Sensing Phoenix charging at him again, Toshiro frowned.
Whoosh!
Toshiro's figure flickered, temporarily creating distance from Aizen, and prepared to use Kido again for a long-range attack, to deal with Phoenix first before focusing entirely on Aizen.
However, this time Aizen would not let Toshiro succeed so easily.
Whoosh!
Just as Toshiro was about to use Kido, Aizen's figure flickered and rushed up to interrupt him.
Although his speed was not as good as Toshiro's, as an existence who had reached the limits of a Shinigami in Zanjutsu, Hakuda, Hoho, and Kido, Aizen's Shunpo were not slow either.
At this moment, while Toshiro was entangled by Aizen, Phoenix took the opportunity to rush up.
Seeing this, Toshiro snorted coldly: "Hmph! Aizen, today I'll show you what speed is that even [Goddess of Flash Yoruichi] has to concede to!"
Shunkuho!
Toshiro let out a loud shout, then began to exert his self-created footwork, Shunkuho, to its fullest.
Whoosh! Whoosh! Whoosh!
When Toshiro pushed his proud speed to its limit, countless afterimages instantly appeared out of thin air.
Then, 'one Toshiro' was seen in front of Aizen, using Zanjutsu, Hakuda, Hoho, and Kido to fight fiercely with him, while 'another Toshiro' stood proudly in the sky, looking down from a height using Kido to attack Phoenix from a distance.
In fact, both the Toshiro fighting Aizen and the Toshiro attacking Phoenix from a distance with Kido were real, not afterimages or anything like that.
Of course, this wasn't Toshiro using some kind of shadow clone technique. It was simply because Toshiro's speed was too fast.
With speed pushed to its extreme, almost teleportation, Toshiro would exchange blows with Aizen in one instant, and then in the next instant move to another location to use Kido for a long-range attack on Phoenix.
So, although in name Toshiro was fighting two against one, dealing with both Aizen and Phoenix simultaneously, in reality, Toshiro was simply using his nearly invincible speed in the entire Shinigami world to conduct two separate one-on-one fights with Aizen and Phoenix respectively.
Boom! Boom! Boom!
While 'one Toshiro' fought with Aizen, 'the other Toshiro' continuously used Kido from the air to bombard Phoenix from a distance.
Although high-level Kido required some preparation time, making it difficult to use while simultaneously dealing with both Aizen and Phoenix, even if he could only use low-to-mid-level Kido like Shakkaho, with a sufficient quantity, they could still pose a serious threat to Phoenix.
Boom! Boom! Boom!
Under Toshiro's relentless bombardment with one Kido after another, Phoenix was blown to pieces, drenched in blood, covered in wounds.
Although he could continuously regenerate using his super-speed regeneration ability, his regeneration speed could not keep up with Toshiro's attack speed. At this rate, before long, Phoenix would be completely blasted to smithereens by Toshiro's long-range Kido attacks.
And although Aizen wanted to save Phoenix, he was blocked by the 'Toshiro before him' and simply could not break free to deal with the 'other Toshiro'.
After Toshiro exerted his nearly invincible speed to its fullest, although Aizen's reaction speed was sufficient to handle Toshiro's attacks, he had no remaining energy to continue helping Phoenix.
'If this continues... Phoenix will definitely be blasted to death by Hitsugaya Toshiro. And if Phoenix dies like this, the seal on Hyorinmaru will gradually be released. Then, things will probably become even more troublesome...' Watching Phoenix being unilaterally brutalized by Toshiro with Kido, Aizen frowned and thought to himself.
If Phoenix were simply blasted to death by Toshiro like this, then the point of Aizen having created Phoenix, this special modified Arrancar in the first place, would be completely lost. So, Aizen absolutely would not let Phoenix be blasted to death by Toshiro with Kido.
'What should I do in this situation? Can I only have Phoenix prematurely detonate the ice-cold power he absorbed from Hitsugaya Toshiro?'
'No, right now Hitsugaya Toshiro is only attacking Phoenix from a distance with Kido, not giving him a chance to get close. If he detonates under these circumstances, with Hitsugaya Toshiro fully prepared, it would be hard to cause him any fatal damage. Moreover, if he detonates now, even I might be affected...'
Facing the current situation, Aizen frowned as well, pondering somewhat troubled.
'There's no choice. It seems I have to use the last resort. Heh, I didn't expect that little thing I made casually back then would actually be put to use...'
Seeing that Phoenix was almost unable to hold on under Toshiro's Kido bombardment, Aizen seemed to make a decision, hesitating no longer.
Whoosh!
After Toshiro bombarded Phoenix with Kido once more, in the next instant he appeared before Aizen again. At this moment, the afterimage of Toshiro in the air had not yet disappeared, so it looked like two Toshiros were attacking Aizen and Phoenix simultaneously.
"Ha!"
Toshiro let out a loud shout, punching towards Aizen with the force of thunder.
However, this time Aizen did not block with his Zanpakuto as before. Instead, he suddenly extended his left hand towards Toshiro.
Then, a purple-black cube appeared in Aizen's hand.
"That is!?" Toshiro said with a start.
Hum—
A pure black light, as pure as a black hole, suddenly burst forth from the purple-black cube. Then the purple-black cube suddenly expanded, enveloping Toshiro, Aizen, and even Phoenix in the distance.
The black light flashed and disappeared, and then Toshiro, Aizen, and Phoenix, along with the purple-black cube, vanished.
Then, Hueco Mundo, which had been shaking violently due to the battle between Toshiro and the others, suddenly became quiet.
Whoosh—
A gentle breeze blew, kicking up a sky full of wild sand, and then returned to calm.
However, the figures of Toshiro, Aizen, and the others could no longer be found anywhere in all of Hueco Mundo. Only the pitted, scarred earth bore witness to the earth-shattering battle that had once taken place here.
Within a certain chaotic, dark space.
"Where... is this place?" Toshiro surveyed his surroundings and murmured unconsciously.
Just now, Toshiro had felt a black light suddenly burst forth, and then, after a dizzying spin, he came to his senses and found himself here.
"This is the dimensional space of the Caja Negación."
A voice suddenly rang out. Toshiro turned and saw that Aizen had also appeared here at some point.
