Aizen Was the Mastermind?

Wang Xun dispersed the Black Coffin in his palm, and the lingering black Reiatsu slowly dissipated into the air.

Tessai Tsukabishi stood still, the complex emotions in his eyes gradually turning into a solemn expression.

He glanced at Wang Xun, then turned to Kisuke Urahara, the name he had just heard replaying in his mind.

Fifth Division Vice-Captain, Sōsuke Aizen.

In his limited memory of him, he was a gentle and proper man.

After a long silence, he finally spoke.

"Urahara, on the way here, you told me that there is an unseen darkness hidden within the Soul Society."

Tessai Tsukabishi's voice was low and heavy, the solemnity in his tone was palpable.

"Are you referring to Aizen?"

Kisuke Urahara put down his notebook, leaned against the lab bench, and crossed his arms.

He didn't answer immediately, his gaze fixed on the distant rock face, as if he were choosing his words.

"Yes."

After a long silence, he finally spoke in a deep voice.

"That's also the main reason I called you here today."

Tessai Tsukabishi's brows furrowed slightly.

"You said before that someone in Soul Society was secretly hunting down the souls and Soul Reaper of Rukongai. Was all of this his doing?"

"That's right."

Urahara's voice was calm.

He took a document from under the lab bench and handed it to Tessai Tsukabishi.

"Tessai, you've been with the Kidō Corps for so long, you might not know these things."

"In recent years, the number of missing souls in Rukongai has increased significantly."

"Furthermore, the number of accidental deaths and disappearances during Soul Reaper's missions has also increased significantly, and all of this data is included."

Tessai Tsukabishi took the document and turned to the first page.

His gaze swept over the densely packed numbers, and his brows furrowed deeper and deeper.

"I haven't really paid much attention to these things."

"That's normal. Besides, this has nothing to do with your job, and moreover..."

Urahara leaned against the edge of the lab bench.

"These cases were all handled very cleanly; each one appeared to be a fake attack, a normal combat casualty."

"If it weren't for a dedicated investigation, the problem would be completely undetectable."

He paused, then glanced at Wang Xun.

"And I was able to discover the truth behind all this because of Wang Xun."

Tessai Tsukabishi raised his head and looked at Wang Xun.

"Oh?"

Wang Xun nodded.

"During the previous joint mission, I personally witnessed Aizen's people taking things from the souls of girls in Rukongai."

"This was not a feint, but a meticulously planned hunt."

Tessai Tsukabishi fell silent.

He closed the file, placed it on the lab table, and glanced back and forth between the two men.

"So, what is your conclusion?"

Urahara and Wang Xun exchanged a glance.

"Sōsuke Aizen is the mastermind behind all this."

Urahara said, word by word.

"He's conducting Hollowfication Experiment, using living people as test subjects."

"He is cultivating his own power base and infiltrating the Gotei 13. His goals and ambitions are immeasurable."

The cave was so quiet you could hear the wind.

Tessai Tsukabishi stood still, motionless.

He kept his hands tucked into his sleeves, and after a long while, he finally spoke.

"Now that we have evidence, why not report it directly to Central 46?"

"Let them order the arrest. With Captain-Commander Yamamoto's strength, what can he possibly do in Seireitei?"

Urahara did not answer immediately.

He turned around, his back to Tessai Tsukabishi, and looked at the distant rock face.

"Based on the intelligence we currently possess, directly exposing ourselves is not a good option."

His voice was soft, yet it carried an indescribable meaning.

Tessai Tsukabishi frowned.

"You mean..."

"What I mean is, if we choose to report this, Aizen will most likely get the news immediately."

Urahara turned around and looked into his eyes.

"Aizen's Zanpakuto abilities are extremely troublesome; his Kyōka Suigetsu is a hypnotic Zanpakuto."

Tessai Tsukabishi frowned.

"Kyōka Suigetsu, a form of hypnosis?"

"Good."

Wang Xun's voice came from the side.

"The ability of 'Kyōka Suigetsu' is Complete Hypnosis, manipulating the five senses; he can make anyone see what he wants them to see."

Tessai Tsukabishi fell silent.

This ability, if it falls into the hands of a cunning person, can indeed be exceptionally troublesome.

"So, what are you going to do now?"

Urahara walked over to Wang Xun and patted him on the shoulder.

"Using Wang Xun as a benchmark, he has successfully infiltrated Aizen's inner circle."

"What we need to do is let him continue to infiltrate Aizen's inner circle, gather evidence, and wait for the right opportunity."

Urahara paused.

"During this time, I will investigate Aizen's Kyōka Suigetsu, and try to find a way to break it."

"When the time is right, I will entrust the solution to a trusted captain, and then, taking advantage of the situation, we will defeat Aizen."

Tessai Tsukabishi remained silent for a long time.

His gaze lingered on Wang Xun for a long time.

"If what you say is true, then it is indeed a formidable enemy."

"Wang Xun... actually got involved in such a dangerous thing?"

Wang Xun nodded.

"Indeed, Aizen has his eye on me. Rather than passively waiting to die, I might as well take the initiative and join the fray."

Tessai Tsukabishi remained silent.

He recalled the miniature Black Coffin from earlier, and what Wang Xun had told him about Aizen's teachings.

"He certainly values you; he's willing to teach you this level of Kidō."

Tessai Tsukabishi's voice was somewhat complicated.

Wang Xun shook his head.

It was just a coincidence.

Tessai Tsukabishi fell silent, then turned to look at Urahara.

"You're right. If reporting to the Central 46 would alert them, then this approach is understandable."

"Tell me, what do you need me to do?"

Kisuke Urahara's eyes lit up.

"Is the Great Kidō priest willing to help?"

Tessai Tsukabishi nodded, his gaze becoming deep.

"With such a terrifying enemy lurking within the Soul Society, it is our duty to join forces and fight against them."

His words were brief, but the meaning was clear.

Urahara smiled, walked to the lab bench, took out a small Reishi communication device from the drawer, and handed it to Tessai Tsukabishi.

"If there's any movement from Aizen's side, or any news from the Central 46, we'll use this to contact them."

Tessai Tsukabishi took the communicator, studied it for a while, and then put it into his sleeve.

"I understand. Is there anything else?"

Urahara thought for a moment.

"That's all for now. Great Kidō, you can go back first. We'll contact you anytime if anything comes up."

"But this matter should be kept secret for now; don't let anyone else know."

Tessai Tsukabishi nodded and turned to walk towards the cave entrance.

When he reached Wang Xun's side, he suddenly stopped.

"Wang Xun, the situation is dangerous, please be careful."

"Based on your current understanding of the Kidō, I can later teach you some more profound things."

Wang Xun was taken aback upon hearing this.

Something even more profound...?

Tessai Tsukabishi looked at him, his gaze carrying a rare hint of gentleness.

"I have traveled far on the Kidō. With your talent, perhaps you can understand what I have mastered."

"I hope you take good care of yourself in this matter."

Wang Xun a warmth in his heart.

Thank you.

Tessai Tsukabishi nodded and strode away.
