Chapter 309: Kore ga, Saigo no Getsuga Tensho
"Is this the power you have right now? How ridiculous!"
After several evolutions, Aizen's appearance at this moment was enough to be called ferocious. He looked at Ichigo and spoke with a voice full of disdain.
Admittedly, Ichigo right now had his reiatsu completely gone for some reason, and the power of his attacks were really good.
But in Aizen's view, this was indeed extremely ridiculous.
Whether it's shinigami or hollow, their battles were essentially battles of reiatsu.
Once all the reiatsu disappears, even though one had gained great strength in a short period of time, this way of becoming stronger was obviously flawed.
For Ichigo, there might be another reason, that is, he was now on a higher-dimension compared to Aizen, and thus his reiatsu was not being perceived by him.
Aizen also thought about this kind of conjecture, but he rejected it immediately.
'Impossible!'
He obtained his current strength with the help of Hōgyoku, and successfully evolving several times. What about Ichigo? Without Hōgyoku, it was obviously impossible to obtain a higher level of evolution than him in such a short amount of time.
So the final conclusion he reached was that Ichigo really gave up all his reiatsu and in exchange, he gained short-lived strength.
