As the Auswählen progressed, Yhwach, the ancestor of the quincies, gradually recovered all his strength. Since he led the quincy masters to attack the Soul Society thousands of years ago, he will attack Soul Society again without a doubt.
The Ishida family is a quincy family, and Soken was once a member of the Sternritters, so he knows a lot of things. He knows better than anyone else, the quincies' blind faith in Yhwach, and hatred for shinigami and the Soul Society.
The reason why they are still hiding now is just because they are not ready for war. Once the war starts that have been planned for a thousand years, the unaware Soul Society will never be able to resist the quincy's revenge if it is not on guard. As for why Soken is willing to tell Mazuru and Aizen about these things.
One is because after walking on the edge of death, he let go of many stubbornness in his heart.
The second is to protect everything he can and wants to protect.
When his grandson Uryuu asked him why his father gave up the glory of quincy for earning money, his answer was: "The things people want to protect are different, so relative disputes might arise for it. One day you will understand, and when you do, you should be able to understand what you really want to protect."
Uryuu didn't understand his father at that time. But Soken, as Ryuken's father, how could he not understand what Ryuken cares about was never money, but the people around him.
Kanae and Masaki obviously did nothing wrong, but they died one after another because of the Auswählen. How can Ryuken let go of this matter easily, after learning the truth, it is understandable that he would hate Yhwach, and the power of the quincy master itself. Similarly, his grandson Uryuu saw hollows' havoc in the world of living very early on, and wanted to protect the human beings, so he didn't mind teaching Uryuu the skills of quincy masters.
For Soken, the meaning of the quincy powers has never been for taking revenge on shinigami, nor to rule the three realms, but to protect the weak.
What the shinigami couldn't protect, the quincies will!
That's all!
So immediately, Soken shared information about the Wandenreich and the Sternritters. After sharing the information he knows, what these two ambitious shinigami will do to him, Soken doesn't know, but after sharing the secret that has been buried in his heart for many years, he just felt a lot easier.
Leaving Soken in the room, Mazuru and Aizen left from there together.
Mazuru glanced at Aizen, "Does Mr. Aizen believe what he said?"
Aizen replied bluntly, "What he said seems to be true. Of course, whether the existence of the Wandenreich is true or not needs to be verified."
For researchers like Aizen, no matter how hidden the Wandenreich is, since they are known to be present in the shadow of Seireitei, there must traces to follow and clues to be found and once the existence of the Wandenreich is confirmed, the authenticity of Soken's words can be regarded as confirmed. Aizen even hoped that what Soken said was true.
In addition to Soul Society and Hueco Mundo, there is also a group of quincies that can compete with Soul Society. That way, he might be able to find more interesting things. After all, the world is too monotonous and boring for him. The ancestor of the quincies, Yhwach, may be a good opponent for him.
…
Soken was left in Las Noches.
Aizen and Mazuru returned to Soul Society. The main purpose of their coming to Las Noches this time was to kidnap Soken, the last pure-blooded quincy master in a way that does not attract the attention of the Soul Society.
Soken died at the hands of Menos Grande and became their food, this reason is very good.
Originally, Aizen wanted to study the secrets of the quincies using Soken, such as the source of its power, etc... But after he learned about Yhwach and the Wandenreich, his interest immediately turned towards Yhwach and Wandenreich.
If what Soken said is true, then in Wandenreich, there should be many powerful quincy masters hiding. The research value of those quincy masters is much greater than that of Soken, an old man who was deprived of most of his power by Yhwach's Auswählen.
…
In the Las Noches.
Soken soon realized that Mazuru and Aizen had left. He still doesn't understand what these two people did in Hueco Mundo which allowed them to control Menos Grande and kidnap him.
"It's confusing, isn't it."
A somewhat indifferent voice sounded beside Soken's ear.
Soken immediately looked at the speaker, who had red hair and a pair of glasses with bone frames on his eyes.
"Human…? No, he's not human!"
Immediately, Soken recognized the special reiatsu on the other party - hollow!
'Hollow without a mask, what exactly is this?'
'What happened in Hueco Mundo?'
"Let me introduce myself, my name is Beelzebub, and I am the leader of the Espada created by Aizen-sama — the Cero (0) Espada. I will be responsible for your daily life in Hueco Mundo."
Beelzebub first introduced himself and then warned Soken, "Besides, if you want to fight against me, you should rather commit suicide. I have hundreds of ways to make you beg for death."
"Let's talk about the simplest method, for example…"
He looked at Soken with a cold smile, "I heard you have a grandson."
Soken's complexion changed, he understood very well that he can't do anything against their will unless they destroy the things Soken strived to protect.
…
Soul Society.
Aizen started eagerly finding traces of Wandenreich. On the other hand, after Mazuru returned, his peaceful daily life resumed.
Going with dates with Nanao, going to Sui-Feng's place from time to time, watching Rangiku getting back to her usual self, and also many things that he previously didn't payed mind to.
Admittedly, there are many bad things in Soul Society. For example, the disgusting Central 46, the aristocrats high above, and the strict and unfair hierarchical order. But in addition to these things, there are actually still good places in the Soul Society.
'If what Soken said is true then…'
The Wandenreich has been hiding in the shadow of Seireitei for a thousand years. While helping their ancestor, Yhwach recover, they are actively preparing for war and take revenge on Soul Society.
'Will the Soul Society really be able to counter these enemies that have been preparing for a thousand years?'
'And can I protect the things around me?'
Mazuru couldn't help thinking about it.
