The Oldest Hero King of Humanity! (Seeking Follow-ups!)

Sosuke Aizen.

Kaien Shiba and Isshin Shiba were, of course, familiar with this name.

So much so that the moment they heard it, the image of Sosuke Aizen immediately surfaced in their minds.

In their impression, although Sosuke Aizen was the captain of Squad 5, he lacked any airs of authority; he was humble, gentle, and kind to others, known throughout the Thirteen Court Guard Squads as a genuinely good man.

They did not know why the black cat held by Gilgamesh would mention the name of Sosuke Aizen.

Could it be that Sosuke Aizen was the mastermind behind the scenes trying to deal with the Shiba Clan?

As soon as this thought appeared, they dismissed it.

Don't joke around.

Sosuke Aizen was born in the Rukongai and was not of noble status; it was impossible for him to have a conflict with the Shiba Clan.

Furthermore, Sosuke Aizen's strength was not particularly outstanding among the captains, so how could he possibly make someone as powerful as Isshin Shiba feel helpless?

Most importantly, it was Hollows that killed their wives; how could Sosuke Aizen possibly command Hollows?

It must be said that Sosuke Aizen had cultivated his daily image so well that both Kaien Shiba and Isshin Shiba were willing to trust him.

Yoruichi Shihouin regretted it the moment the name slipped out.

Now was simply not the time to deal with Sosuke Aizen.

This was not only because of Sosuke Aizen's strength but also because he hid his true nature too deeply.

Yoruichi Shihouin knew that even if she exposed the truth, no one would be willing to believe her.

Otherwise, she and Kisuke Urahara would not have defected from the Soul Society decades ago.

Right now, under the suspicious and probing gazes of Kaien Shiba and Isshin Shiba, Yoruichi Shihouin knew she had to find a way to gain their trust.

Otherwise, she might alert the enemy and startle Sosuke Aizen, causing the plans she and Kisuke Urahara had spent decades crafting to go down the drain.

However, would Kaien Shiba and Isshin Shiba be willing to believe her?

Just as Yoruichi Shihouin was feeling anxious, Gilgamesh reached out and gently stroked her small head, saying warmly, "This is not the place to talk. You should have a secret underground base nearby; take us there."

Yoruichi Shihouin was stunned; she did not know how Gilgamesh could have known about this.

One had to know that this secret underground base was a secret between her and Kisuke Urahara, and no one else should have known about it.

But soon, as if Yoruichi Shihouin had thought of something, she muttered to herself, "The future..."

Gilgamesh did not explain.

He had not seen the relevant future, but in the future of the original Bleach storyline, Yoruichi Shihouin did indeed bring Ichigo Kurosaki into the secret underground base to train for his Bankai.

Yoruichi Shihouin had absolute trust in Gilgamesh.

Yoruichi Shihouin said to Kaien Shiba, "The secret underground base is a bit far from here; you should take us there using Flash Step."

Kaien Shiba's heart was already filled with doubts.

In order to resolve these doubts, and to learn more about the future related to himself from Gilgamesh, he followed Yoruichi Shihouin's instructions.

Guided by Yoruichi Shihouin, Kaien Shiba and Isshin Shiba traveled rapidly using Flash Step.

Soon, they arrived at the secret underground base.

Looking at the vast space of the secret underground base, Kaien Shiba and Isshin Shiba were stunned, their hearts filled with shock.

They had never imagined that there would be such a large space underground; even when they looked as far as they could, they could not see the boundaries.

At the same time, they were curious about who had created such a vast underground space—was it that black cat?

But how could that black cat have created it?

Come to think of it, why could that black cat speak human language?

Amidst their confusion, Yoruichi Shihouin jumped down from Gilgamesh's arms to the ground, and then a puff of smoke rose from the black cat form of Yoruichi Shihouin.

Under the probing gazes of Kaien Shiba and Isshin Shiba, the smoke dissipated, revealing a fully dressed Yoruichi Shihouin.

Seeing Yoruichi Shihouin, Kaien Shiba and Isshin Shiba were both stunned, their eyes filled with disbelief.

As the former captain of the Second Division and now a wanted criminal who had defected from the Soul Society, they naturally recognized her.

Among them, Kaien Shiba even had a deep friendship with Yoruichi Shihouin.

But they never expected that the black cat Gilgamesh had been holding would actually be Yoruichi Shihouin.

Under normal circumstances, even with their past friendship, Kaien Shiba and Isshin Shiba would likely have been on guard, perhaps even prepared for battle.

But things were different now; compared to that, they were more concerned about the future related to themselves.

After Isshin Shiba reacted, his brows furrowed involuntarily, and he said in a deep voice, "Yoruichi Shihouin, what is going on here? I hope you can tell me."

Kaien Shiba did not speak, but his gaze was also fixed tightly on Yoruichi Shihouin.

Seeing this, Yoruichi Shihouin hesitated, her heart still full of concerns, unsure whether she should reveal the events of that year.

Gilgamesh spoke up at this moment, "Speak, it is fine. The enemy of an enemy is a friend; whether they like it or not, they will become your allies in the future."

Gilgamesh's words were like an adrenaline shot for Yoruichi Shihouin.

Yoruichi Shihouin took a deep breath, her eyes turning suddenly cold as she looked at Kaien Shiba and Isshin Shiba and began, "Fine, I will tell you everything."

"Back then, it was Aizen who triggered the Hollowfication of Shinji Hirako and the others."

"In truth, he had been researching how to break the barrier between Soul Reapers and Hollows for a very long time; Shinji Hirako and his group were merely Aizen's test subjects."

"Because Soul Reapers and Hollows have always been opposing existences, and Hollowfication is something that is never permitted to exist."

"That is why Central 46 listened to Aizen's words and ordered the execution of Kisuke, Tessai, and Shinji Hirako's group."

"As for what happened afterward, you should already know: I broke into the trial chamber to rescue Kisuke and Tessai, and assisted Shinji Hirako and his party in fleeing to the Human World."

Yoruichi Shihouin's words were so absurd that Kaien Shiba and Isshin Shiba could not help but exchange a glance, both seeing the skepticism in each other's eyes.

Empty words carry no weight.

On one side was a wanted criminal who had defected from the Soul Society, and on the other was the current captain of Squad 5, a well-known "good guy" of the Thirteen Court Guard Squads; any normal person would choose to believe the latter.

Yoruichi Shihouin knew it would be like this, and a look of helplessness could not help but appear on her face.

She did not know how to convince Kaien Shiba and Isshin Shiba.

It was at this moment that Gilgamesh spoke up: "Since you are unwilling to believe her, would you be willing to believe me?"

Gilgamesh's words drew everyone's attention toward him.

Only then did Kaien Shiba and Isshin Shiba suddenly realize something they had been ignoring all along.

That was, why was the black cat that Yoruichi Shihouin had transformed into so docile while being held by Gilgamesh, and why did she seem to enjoy his petting so much?

This appearance was exactly as if she had been conquered by Gilgamesh.

Originally, they had assumed that Gilgamesh's background was that of a noble, but now they no longer thought so.

After all, which noble could conquer Yoruichi Shihouin?

One must remember that Yoruichi Shihouin herself hailed from the Shihoin House, one of the Four Great Noble Clans.

So, who exactly was Gilgamesh?

Kaien Shiba could not help but ask this question: "Who exactly are you?"

Before Gilgamesh could answer, Yoruichi Shihouin spoke in a tone filled with pride, arrogance, and reverence: "He is the oldest King of Heroes of humanity, and the archetype of all human mythology!"
