"Long time no see, young reaper. You are still so interesting," Aizen turned to look at Kurosaki Ichigo and explained calmly. "The reason why I haven't used the ability of Kyōka Suigetsu on you is because it is unnecessary. Compared with other captains, you do have a greater chance of hurting me. I have long guessed that the Soul Society will regard you as a savior and let you take a risky attack. Considering this, I only need to prevent being attacked by surprise. This is very simple for me, after all, the largest visual blind spot of a living creature is the back of the neck. You don't think I would ignore this weakness and easily join this war, do you?"
Until now, these Shinigami captains still don't know his true strength. But even so, Aizen has made sufficient preparations, which can be said to be foolproof. Among them, the million shields set up at the back of his neck are one of his backup plans.
No one understands Reiatsu better than him. Aizen's Reiatsu talent is just like Yamamoto's Bankai and Zaraki Kenpachi's slashing technique, both of which are super-standard powers. Of course, this talent cannot be compared with monsters like Uehara Shiroha. But among the Shinigami, it is a ceiling-level existence.
Therefore, Aizen has an extremely terrifying Reiatsu control.
Kyōka Suigetsu is actually just the ability to control the five senses and spiritual perception. Although this ability is very strong, it is not so strong that it is completely unsolvable. In fact, as long as the Reiatsu of the person being controlled is strong enough, there are still ways to break or resist the illusion created by Kyōka Suigetsu.
However, Aizen's Reiatsu talent is too strong. Combined with Aizen's overwhelming Reiatsu, Kyōka Suigetsu has become a "field control artifact." Moreover, Aizen can also transform this Reiatsu into various powerful techniques.
Among them, the Single Shield and the Million Shields are very powerful Reiatsu defense moves. These are unique skills specially developed by Aizen to deal with warfare situations.
The Single Shield transforms Reiatsu into a glass-like solid defense, which can block the attack of a Captain's Shikai. The advantage is that it can be activated at any time, and the defense is not weak. The disadvantage is that it needs to be used consciously, requiring Aizen's direct attention.
The Million Shields combine one million layers of Reiatsu defense into one, forming an indestructible defensive barrier. The advantage is that it can be triggered passively and can defend against Bankai killing moves. The disadvantage is that it needs to be set up in advance and consumes a lot of Reiatsu.
With this Million Shields, Aizen has an extra "resurrection armor," so he naturally has the capital to be extravagant in battle. However, he was only extravagant in front of Kurosaki Ichigo. Against Uehara Shiroha, such a move is not good enough. Aizen knew this very well.
He thought he could still hold Kurosaki Ichigo. He has always been interested in this kid's special power.
As he spoke, Aizen gently swung his sword. He didn't take this blow seriously; he just wanted to repel Kurosaki Ichigo. Sure enough, facing Aizen's casual blow, Kurosaki Ichigo was like a frightened deer, quickly flying back and distancing himself from this dangerous man.
Although his Bankai Tensa Zangetsu is now restored to its original state, which means that his Reiatsu is already at its peak, Aizen's previous suppression was too strong, which caused a great shock to his young mind. Therefore, Kurosaki Ichigo was a little restrained and didn't dare to fight the opponent in close combat.
This invisibly contributed to the enemy's arrogance.
As a result, Aizen came to Kurosaki Ichigo again with a Shunpō, reached out and touched the opponent's "exaggerated" chest muscles, and exclaimed: "You have grown up very well, and you really didn't disappoint me. As a Shinigami, you are really interesting."
For him, everything is under control. Kurosaki Ichigo has really become stronger, and he is coming to his door. When the Hōgyoku awakens, he will be able to completely understand the secret of the other party's power and use this power for his own benefit. Then, he will surpass Uehara Shiroha.
This world is destined to be ruled from the top by him. The top of the sky can only accommodate one god. He is not afraid of the Reiatsu of Yamamoto, let alone Uehara Shiroha.
"What on earth are you talking about? I don't understand!" Kurosaki Ichigo retreated again and activated his "Deaf Word D" ability - his mental technique of blocking out intimidation.
He felt a little regretful that he should have used all his strength just now. After all, before this, Captain Unohana had warned him that after the battle, he would probably only have one chance to attack. If the sneak attack failed and the opponent released his Zanpakutō, he would be at a tremendous disadvantage. Once hit by Kyōka Suigetsu, he would never be able to defeat Aizen again.
But because of some hesitation in his heart, Kurosaki Ichigo only used his Bankai and did not activate his Hollowification. This allowed Aizen to escape unscathed.
Aizen said calmly: "It's not that you don't understand, you're just a little confused. Now, you must be regretting not turning on the Hollowification just now. You only had one chance to attack, but you didn't use your full strength. This is your mistake, and also your biggest flaw."
