Bleach: Starting with Marrying Retsu Unohana

After resting on the ground for a while, Aizen slowly stood up. He took a breath and adjusted his breathing and state before respectfully addressing Araki.

"Hehe, one day you will reach my level."

Upon hearing this, Araki gently touched his chin, then smiled faintly at Aizen, who was putting on an act.

"Ha ha……"

Aizen didn't say anything about this, but simply smiled lightly, just like Araki.

"Sousuke, let's go..."

"Come practice with me outside~"

Just as Aizen chuckled, Araki tossed him a wooden training sword and said with a smile.

"Um?!"

Aizen stared into thought at the wooden sword in his hand, his smile abruptly vanishing.

"Araki-sensei, could it be that you intend to..."

Aizen's hand, which was holding the wooden sword, trembled slightly at first, and then he looked at Araki and asked.

"Just as you expected, next I will teach you the slashing technique from 'Slashing Fist and Walking Ghost'!"

Araki looked at Aizen and explained.

"Araki-sensei, is it a bit... a bit... to spar with you right now?"

Aizen gripped the wooden sword in his hand, feeling that it was too early to fight Araki now.

"Aizen, you can rest assured! I have plenty of time. As for the work of the 'First Division,' I have entrusted it all to your Vice-Captain Saito. Don't worry that I will overwork myself by sparring with you."

Araki looked at Aizen's wry smile, and his own smile became incredibly bright.

"Teacher Araki, you've misunderstood me! I meant that my understanding of swordsmanship is extremely superficial. All my learning about 'slashing' was only superficial at the 'Spiritual Arts Academy'! I haven't had any in-depth or systematic training. With my half-baked swordsmanship, wouldn't it be a bit too early for me to start a fight with you?!"

Aizen addressed Araki with the most tactful words he could muster.

"It's getting late..."

Araki listened to Aizen's words, smiled, walked up to Aizen, and gently patted Aizen's shoulder.

"Aizen! You need to have confidence in yourself, you're a genius!"

"The teaching of geniuses is about being different from the norm."

“If it were someone like Kyoraku, Ukitake, or Tokina, I would make them train their fundamentals for a full hundred years, but you don’t need that! You can spar with me right from the start! I have high hopes for you…”

Araki was making grand promises to his beloved apprentice.

"I……"

"Thank you so much, Araki-sensei!"

Aizen remained silent for a long time before finally expressing his heartfelt gratitude to Araki.

"Hehe, it's nothing~"

"Who are we to each other? You're my beloved disciple!"

"It is my duty to teach you with all my heart! You don't need to say thank you to me!"

Araki said, pulling the person in front of him along, and mentally speaking a lot of words to Aizen, who was speaking in a mosaic-like manner, before leaving the captain's room of the 'First Division'.

Double Killing Hill...

Since the two monsters were crippled by Araki's sword, this place has become an empty space!

As for the Twin Blades that Araki had severed, Araki naturally sent them to the Zero Division and entrusted them to the Sword God, Wang Yue, for repair. In response, Wang Yue looked at the enormous Twin Blades and said, "Araki, you are my true friend!"

Araki ignored Wang Yue's dissatisfaction and gave him something to do...

With the Sōkyū Hills temporarily without Sōkyū, it became the most suitable place for Araki to teach Aizen.

"Sousuke, make your move!"

After Araki and Aizen set up their stances on this desolate hill, Araki did not launch an attack first. Instead, he politely smiled at Aizen.

"Suck……"

After hearing Araki's words, Aizen took a deep breath. He stared intently at Araki, showing no intention of attacking. He was currently searching for Araki's weaknesses. Facing a monster like Araki, he dared not be careless, because any carelessness would lead to his immediate defeat.

"Araki-sensei, please go first~"

After a moment, Aizen looked at Araki, who was full of flaws yet had no weaknesses, raised his wooden sword and assumed a defensive stance. Since he couldn't find Araki's weakness, he might as well launch a counterattack.

"In that case, I'll go first..."

"Sousuke, don't be too nervous, relax! I won't take it too seriously. After all, this isn't a battle between us; this sparring is mainly for teaching purposes."

Araki looked at the extremely nervous Aizen Sousuke and couldn't help but laugh.

"call……"

"I wasn't quite in the right mindset, and I hope you'll forgive me, Araki-sensei!"

Upon hearing this, Aizen's expression changed slightly. Just as Araki had said, Araki, as his teacher, would definitely not take him seriously! With this in mind, Aizen's previously anxious heart relaxed a little.

"Here I come..."

As Araki spoke, he brandished his wooden sword and slashed at Aizen.

And it was precisely at the moment of Araki's operation...

Aizen's pupils widened infinitely at this moment.

In Aizen's eyes, Araki became a blur, appearing before him in an instant, his wooden sword raised high above his head, poised to strike Aizen with a steady slash...

But Araki's ordinary wooden sword kept magnifying in Aizen's eyes, and magnifying it again and again...

In the blink of an eye, it became as vast as heaven and earth!

"I'll die! If I get hit by this blade, I'll definitely die!"

Cold sweat poured down Aizen's forehead. At this moment, his body was no longer under the control of his brain. He had completely forgotten about hiding his true strength and instinctively retreated backward.

"boom!!"

It was precisely because Aizen used his exquisite Shunpo technique to retreat that Araki's blade landed steadily on the ground in the instant he retreated.

Immediately afterwards, that half of the hill vanished without a trace before Aizen's very eyes.

"Sōsuke, why are you running away?!"

"Our lesson today is about slashing techniques, not some kind of instant step!"

Araki looked at Aizen as he fled and said with a chuckle.

"Um, Araki-sensei, do you really think I could have blocked that stab just now?"

After hearing Araki's words, Aizen looked at the severed hills, sweating profusely, and asked Araki a question.

"Of course! I believe you can do it..."

Araki smiled slightly upon hearing this.

"I'd be a fool to believe you!"

Aizen's eyelids twitched slightly after hearing Araki's words. That old geezer Araki is really wicked!

They just know how to deceive this ignorant and young child who is not even a hundred years old!

That wretched Araki Commando! I was too young and powerless!

"Sousuke, are you distracted during our battle?"

Just as Aizen was thinking, Araki, who was originally hundreds of meters away from Aizen, was now in front of him, with one finger pressed tightly against Aizen's forehead.

"I……"

Before Aizen could think any further, Araki had already launched the projectile at him.

"Oh!"

With a deafening roar, Aizen's body exploded in mid-air, creating a sonic boom, before crashing into the hills below, creating a huge crack in the hills.

"Cough cough..."

Aizen lay in the crevice, coughing up blood continuously.

"This old guy is serious!"

Aizen roared at Araki in his heart.

"Shh!"

Before Aizen could think further, Araki had already released his Zanpakuto. A shimmering, azure light descended from the sky, helping Aizen recover from his injuries and regain his strength. It even subtly altered Aizen's body, elevating his physique to a new level.

"call……"

Aizen breathed a sigh of relief. It seemed that Araki-sensei did not intend to kill him. Rather, this was Araki's teaching method, which involved his students constantly struggling between life and death before breaking through.

"Araki-sensei, didn't you say today was a lesson on swordsmanship? That wasn't swordsmanship just now!"

After letting out a sigh of relief, Aizen turned to Araki in front of him and asked a question.

The ability that Araki just displayed was clearly physical combat!

"Huh? Sousuke, is wielding a sword such an inconvenient thing?!"

Upon hearing this, Araki addressed Aizen with a lecture.

"I……"

Aizen's mind was in turmoil at this moment.

"'Slaying Fist and Slaying Demon' are inseparable! Since you're a genius, Sousuke, let's train together! Sousuke, if you want to become a true strongman, you can't have any weaknesses..."

As Araki spoke, he threw his second punch at Aizen.

"I……"

Aizen was clearly prepared for Araki's punches, and he dodged them with a simple sidestep.

"boom!"

And at that moment, the cracked earth behind Aizen completely shattered into countless fragments...
