Facing Genryūsai Shigekuni Yamamoto's attack, Aizen's lips curled into a faint smile. He did not take Genryūsai Shigekuni Yamamoto's attack seriously at all.
Because, in Genryūsai Shigekuni Yamamoto's eyes, Captain Ailin was Aizen Sosuke!
Sure enough—
"Wait—"
"Captain-Commander Yamamoto!"
"Captain Ailin!"
Amid the captains' cries of alarm, Genryūsai Shigekuni Yamamoto's attack was not directed at Aizen, but at Captain Ailin!
"Oh?"
Ailin glanced at Aizen Sosuke.
Ailin had wielded Kyoka Suigetsu for some time as well.
So, when Aizen controlled Genryūsai Shigekuni Yamamoto and muddled his perception of spiritual pressure, Ailin had already guessed Aizen Sosuke's intentions.
He merely wanted to use Ailin to buy time.
However, Ailin was also looking forward to Aizen Sosuke's growth, so he allowed Aizen Sosuke to proceed as he wished.
Genryūsai Shigekuni Yamamoto's attack was likewise within Ailin's expectations.
Likewise, faced with Genryūsai Shigekuni Yamamoto's Futsuri, Ailin did not hold back. Cold, biting frost radiated from the Zanpakuto in his hand as he swung it at the charging Genryūsai Shigekuni Yamamoto.
"Slash!"
"Boom!"
One horizontal, one vertical!
The horizontal strike was Genryūsai Shigekuni Yamamoto's Futsuri, containing six thousand degrees of heat.
The vertical strike was Ailin's slash, suffused with boundless freezing energy.
Red and white spiritual pressure intertwined above Sōkyoku Hill. The collision of ice and fire was like a miniature nuclear explosion.
The shockwave erupting from their Zanpakuto spread outward, sweeping across all of Sōkyoku Hill.
Fortunately, every Soul Reaper currently on Sōkyoku Hill was a powerhouse with captain-level strength.
Even the injured Vice-Captains, along with Ichigo Kurosaki and Shino Madarame, were shielded behind Retsu Unohana and suffered no significant effects.
"Bang—"
The collision between Ailin's and Genryūsai Shigekuni Yamamoto's spiritual pressure shattered the spiritual pressure Aizen had used to control Genryūsai Shigekuni Yamamoto's five senses, restoring the true scene before his eyes.
