Bleach: Starting with Marrying Retsu Unohana

He seemed to have always lived under the watchful eyes of others, never letting his guard down for a moment. Now, thinking about it, since he was retired anyway, he might as well take advantage of this invasion by the traveling monsters and have some fun! He could also give that wretched apprentice, Araki, who had been causing him trouble every moment during his time as captain-general, a good dressing down!

"Master! You are the captain, how could you do such a thing?"

Yoruichi was stunned; she hadn't expected things to turn out this way.

So, Master Yuan Liuzhai planned to join these young people in their antics?

Isn't this utterly ridiculous?! It's like a bright but foolish college student taking his over-100-year-old great-grandfather to a disco, claiming it's to let his great-grandfather be trendy before he dies...

"The captain? He's retired!"

Upon hearing this, Yuan Liuzhai smiled.

"Don't call me Founder or Master; just call me Yuan Liuzhai."

"While I was fooling around with you, I wasn't Yamamoto Genryusai, nor was I Genryusai Shigekuni; I was just a simple Genryusai without any surname or identity..."

"Little Yoruichi, you can understand what I'm saying, can't you?!"

Yuan Liuzhai's words seemed to carry a hint of threat.

"Yes, we all understand!"

Yoruichi nodded vigorously, moving her head up and down repeatedly.

"What are your plans next?"

Yuan Liuzhai asked Yoruichi directly, inquiring about her next plans.

"Take Ichigo Kurosaki to learn Bankai."

Yoruichi dared not hide anything and answered truthfully.

"Really? Let's go then~"

As Genryusai spoke, he had already lifted up the unconscious Kurosaki Ichigo, Ishida Uryu, Chad Yasutora, and Inoue Orihime from the ground, and urged Yoruichi onwards.

"Sigh, my secret base is doomed!"

Upon hearing this, Yoruichi sighed with a sense of wanting to cry but having no tears left.

"Would you like to go?"

Yuan Liuzhai urged him on, clearly dissatisfied.

"Go, go, go! Of course we'll go..."

Yoruichi dared not say more and immediately used Shunpo to lead the way for Genryusai.

"Ok!"

Genryuzhai nodded in satisfaction after watching Yoruichi's actions.

In an instant, the two, like ghosts in broad daylight, stealthily made their way towards the Hill of Twin Demons! Although the Gotei 13 was fully mobilized to capture the Ryoka, not a single one of them noticed Yoruichi and Genryusai's whereabouts...

Apart from Aizen and others.

"Lord Aizen, Ichigo Kurosaki has been kidnapped by Lord Genryusai."

When Aizen returned to the laboratory he had established in 'Yūkigai', he heard Tōsen, who had been staring at the computer screen, calling out anxiously.

"what?!"

Aizen was stunned by what he heard.

"What should we do next?"

Tosen looked at Aizen and asked softly.

"Rest assured, everything is under our control."

Aizen was verbally trying to persuade Tosen, but in reality, he himself didn't know what to do.

He knew the whereabouts of all the captains of the 'Gotei 13', but the problem was that Genryusai was not a captain of the 'Gotei 13'!

At the same time, Genryusai was one of the few in the Seireitei who hadn't been hypnotized by Aizen's Kyosuigetsu. After all, Aizen didn't have a suitable reason, nor dared to release his Zanpakuto in front of Genryusai. He couldn't just go to the Spirit Arts Academy, pat Genryusai on the shoulder, and say, "Hey, old man, are you still in class? Stop class! What's the point? You're too old for that; you should rest. Come on, I'll put on a show for you during break—watch me release my Zanpakuto!" Saying something like that would get you burned at the stake! In other words, Genryusai was a so-called uncontrollable factor.

"Sigh, Ichigo, good luck to you~"

Aizen, who was acting as the 'godfather', didn't know what to do at the moment. He hadn't obtained the Hogyoku yet, so he dared not fight Genryusai.

At this moment, Aizen could only place his hopes on Ichigo Kurosaki, hoping that Ichigo could protect himself and prevent his experiments, which he had conducted for over twenty years, from being disturbed because of Genryusai.

Meanwhile, Aizen didn't have time to deal with Ichigo Kurosaki's situation; he had more important things to do, and it was time to start recovering the Hogyoku.

On the other side, Yoruichi and Genryusai soon arrived at the training base that Yoruichi Shihouin and Kisuke Urahara had built at the foot of Sōkyō Hill.

"Oh! This is the place where you and Kisuke Urahara, along with Shinji Hirako and the others, hid from the pursuers in the Soul Society before you defected from the Gotei 13, right? It's spacious and unique, with everything you should and shouldn't have!"

Genryusai left Kurosaki Ichigo and the others in the hot spring in the center of the cave, then chuckled and spoke. This generous and unique form of address was a compliment to Urahara and Yoruichi.

"Thank you for the compliment."

Yoruichi didn't dare say anything and could only nod repeatedly like a chicken pecking at rice.

"This hot spring is remarkably similar to the recovery spring created by that kid Kirinji using Uno Retsu's Zanpakuto, except that its recovery effect is considerably weaker..."

Yuan Liuzhai stood by the hot spring and, with just a glance, revealed the original form of the hot spring.

"Hehe, this was indeed created by Kisuke Urahara in imitation of the hot springs at Kirin-ji Temple."

Yoruichi nodded slightly in response, offering no rebuttal.

"What is that thing?!"

As Yuan Liuzhai spoke, he seemed to be drawn to something else. He looked at the props that resembled human rubber models by the hot spring and asked a question.

"That's the Transcendental Body! It's a tool developed by Kisuke Urahara specifically for training Bankai. That kid Urahara used this thing called the Transcendental Body to master Bankai in just three days, which is quite an impressive achievement!"

Upon hearing this, Yoruichi immediately began to introduce Genryuzhai.

"Oh? Interesting..."

"If it's really that effective, then it's worth promoting!"

Genryusai never expected that this seemingly ordinary rubber model would have such amazing effects. After a slight pause, he immediately spoke to Yoruichi.

"In fact, this item called the Transcendent Body also has certain limitations, namely, those who lack sufficient spiritual power cannot successfully cultivate Bankai..."

After hearing what Genryusai said, Yoruichi spoke awkwardly.

Yes, the Transcendent Body only allows those who are already capable of cultivating Bankai to cultivate it faster, but it cannot allow those with seventh or eighth-rank spiritual power, who haven't even scratched the surface of Bankai, to actually cultivate it.

"..." Upon hearing this, Yuan Liuzhai remained silent for a moment before trying to find a way to add, "That's great! At least from now on, anyone who reaches the captain level of spiritual power can successfully cultivate Bankai, which can be considered progress."

At this point, Genryusai himself didn't know what he was saying anymore. What did he mean by saying that anyone with a Reijutsu level of Captain could successfully master Bankai? So far, there doesn't seem to be a single case of someone with a Reijutsu level who couldn't complete Bankai, right?! (Zaraki here has already mastered Bankai.)

"..."

For a moment, Yuan Liuzhai fell silent, and Ye Yi also fell silent.

The two were too far apart in age and had nothing in common.

And so, time flew by in silence...

About four or five hours later, Kurosaki Ichigo, Ishida Uryu, Chad Yasutora, and Inoue Orihime, who had been soaking in the hot spring, slowly opened their eyes.

"My head hurts so much, what happened?"

"I only remember being knocked down by an old man..."

"Not only you, but I, Inoue, and Yasutora were all killed!"

"Taotora was probably the first to be taken down, Kurosaki Ichigo, you were the second, Inoue was the third, and I was the last! I don't know what happened after I was defeated, but it seems we were rescued. To be honest, that old man's strength was on a completely different level from ours, so losing to him is quite normal..."

When Ichigo and the others opened their eyes, they were greeted by an unfamiliar ceiling and surrounded by warm pool water. The four of them soaked in the warm water, constantly recalling the events that had occurred before they fainted...

It seemed that none of them noticed that Genryuzai was sitting not far from them, quietly brewing tea, and Ishida Uryu's words stopped abruptly the moment he saw Genryuzai.

"Go on, don't mind this old man~"

When Yuan Liuzhai noticed that Kurosaki Ichigo and the others had suddenly fallen silent, he knew that they must have found him. Yuan Liuzhai calmly poured himself some tea, then turned around and smiled at the people in the pool.

"What's your purpose?"

These words were spoken by Yulong.

"What do you mean?"

This sentence was spoken by Ichigo Kurosaki.

"Sir, did you save us?"

Orihime Inoue's first concern was not whether Genryusai had attacked them, but whether Genryusai had saved them afterwards.

"..."

Chado Yasutora watched Genryusai silently, wary and without uttering a word.

"Let me do them one by one..."

"First of all, I have no ulterior motives!"

"Secondly, it was indeed me who saved you, and I saved you simply because I wanted to!"

Genryuzai looked at Ichigo and the others and answered softly.

"..."

However, Genryusai's answer clearly failed to convince Ichigo and the others, and they continued to look at Genryusai Shigekuni with wariness.

"Let me explain the details of this matter."

Just then, Yoruichi Shihouin, wearing an orange tracksuit, walked up to the group and comforted Ichigo Kurosaki and the others.

"Who are you?"

To everyone's surprise, after glancing at Yoruichi, Kurosaki Ichigo had absolutely no recollection of her and asked her a question.

"Bang! Bang! Bang..."

Yoruichi's eyes twitched slightly in anger at Ichigo's words, and she punched each of Ichigo and the others hard on the head.

Then, she said, "How rude of you! Have you even forgotten your own teacher? It's me, Yoruichi Shihouin..."

"Eh?!"

"Are you Mr. Yoruichi?"
