"What?"
"A Kido barrier?!"
The watching captains were instantly stunned,
then immediately understood what was going on and turned to look at Aizen inside the barrier,
clearly, Aizen had set up this barrier in the training ground beforehand. He had prepared for this long before the captaincy challenge began.
He would never let himself fall into a disadvantageous position.
"It's an extremely powerful Kido barrier..."
Byakuya Kuchiki looked grave,
even Head Captain Yamamoto's strike couldn't break through it. Clearly, the barrier Aizen had set up in advance was incredibly powerful.
Head Captain Yamamoto furrowed his brow and swung Ryūjin Jakka once more, striking the barrier,
but the barrier merely trembled, showing no sign of collapsing.
"I put a great deal of effort into preparing this barrier."
Aizen had regained his composure at the center of the barrier, evidently confident in its strength,
"Even Head Captain Yamamoto won't be able to break through it in a short time."
"Unless Head Captain Yamamoto uses Bankai."
Aizen looked at Nara Dan with a faint smile,
his meaning was clear: Head Captain Yamamoto obviously wouldn't use Bankai just because of a newly appointed captain.
As the Zanpakutō with the widest attack range, Head Captain Yamamoto's Bankai would inevitably kill the fragile Spirit Bodies in Soul Society's Rukongai, and might even have a huge impact on Soul Society as a whole.
For Head Captain Yamamoto, unless it was absolutely necessary, he wouldn't casually use a weapon as devastating as Bankai.
"So..."
"Now you have a choice..."
Aizen faced Nara Dan, his threat plain to see,
"Either surrender..."
"Or try to resist..."
"Then watch as I crush you without effort."
Looking into Aizen's deep eyes, Nara Dan knew
that Aizen's real goal wasn't to capture him alive, but to force him to reveal his trump card.
