Aizen Was Stunned
Aizen's Zanpakuto ability was called Suigetsu. It could influence other people's senses, but it could not create something from nothing; it was more like a sleight-of-hand technique.
For example, when he had still been the vice-captain of the 5th Division, he had used Suigetsu on Sōsuke Aizen, then had an ordinary squad member follow him, making him think that person was Aizen.
Because of Suigetsu's formidable ability, not only had he fooled Sōsuke Aizen, but he had deceived the other captains as well.
It was precisely because that attempt had been such a complete success that Aizen had dared to use fake death to pull off Golden Cicada Sheds Its Shell this time.
But playing dead was no easy matter. A Bleach's Spiritual Pressure was like an ID card—everyone's was different. That made it impossible to use someone else as a stand-in.
More importantly, Aizen was now the captain of the 5th Division. A captain's death was no trivial matter. The captain of the Fourth Division would certainly come personally to inspect the body. If he used someone else as a substitute, he would inevitably be exposed.
Therefore, Aizen had decided to use his own Zanpakuto as his stand-in, and there were two advantages to doing so.
First, a Zanpakuto was a product derived from a Bleach's spiritual power, so their Spiritual Pressure signatures were completely identical.
Second, with Aizen's Zanpakuto, Suigetsu, serving as the foundation of the illusion itself, the illusion would be stronger and harder for others to detect.
Aizen's idea was not wrong. In fact, in the original plot, he had indeed successfully fooled everyone with this move.
Unfortunately, he had run into Zhang Miao this time.
Zhang Miao had originally been content to watch the show and had not intended to make things
