I'm in Bleach, starting with Unlimited Blade Works.

However, this means that Shirayuki's freezing ability cannot be fully utilized.

After all, no matter what, Sode no Shirayuki is a "top" among them, and can be considered on par with Ryujin Jakka, Hyōrinmaru, and Genryōmaru.

Moreover, unlike Hyōrinmaru who condenses moisture in the air into ice, Sode no Shirayuki is the coldest being, capable of freezing everything she touches.

In theory, Sode no Shirayuki is not countered by Ryujin Jakka.

If Rukia's spiritual pressure were to reach the level of Captain-Commander Yamamoto, she would be someone who truly has the ability and strength to threaten Captain-Commander Yamamoto.

Of course, the stronger Sode no Shirayuki's abilities, the higher the requirements for using her.

If the user is not careful, they will be severely injured by Sode no Shirayuki's abilities.

However, if Rukia learns "Data Swordsmanship," these weaknesses of Sode no Shirayuki will not be an obstacle for Rukia at all. On the contrary, they will allow Rukia to control Sode no Shirayuki's abilities better and faster.

"Rukia, although I didn't draw my sword during our fight just now."

“However, from the very beginning, I used my ‘data swordsmanship’.”

“Under my ‘Data Swordsmanship,’ you have no secrets from me.”

"And this is what I'm going to teach you."

"What? This is 'Data Swordsmanship'?"

Rukia looked up in surprise.

At that moment, all the fear in her heart turned into excitement.

Only by personally experiencing that kind of despair can one know just how terrifying this so-called "data swordsmanship" truly is.

"of course."

Erin nodded and chuckled, "However, Rukia, mastering true 'Data Swordsmanship' is no easy feat."

"If you fail to learn 'Data Swordsmanship' in the end, your future swordsmanship will not only fail to improve, but may even cause you to lose your ability to fight in close combat, turning you into a Grim Reaper who can only fight using Kido."

"So, Rukia, with such serious side effects, are you sure you still want to learn swordsmanship?"

Erin wasn't deceiving Lucia by saying that.

If one learns "data swordsmanship" but lacks the ability to quickly gather intelligence, one will easily be distracted by gathering intelligence and defeated by the opponent.

If one cannot change their "mindset" over time, they will become completely isolated from close combat.

Of course, even so, using Kido with the ability of "Data Swordsmanship" can greatly enhance Rukia's strength.

"Yes, teacher, I want to learn!"

"Please teach me, teacher."

Rukia picked up the asahi that had fallen to the ground and put it back in her waistband, then bowed to Erin.

"Haha, this is exactly what I was going to teach you. I'll teach you anytime you want to learn."

Next, Erin and Rukia returned to the cherry blossom tree and sat down. Then, Erin began to describe the training method of "Data Swordsmanship" to Rukia.

"Rukia, everything in 'Data Swordsmanship' is based on 'data'."

"The so-called 'data' is to quantify everything in the world in a way that we can understand."

"For example, if you swing your sword now and leave a one-millimeter mark on the killing intent stone, then I will rate the power of your sword strike as 1..."

“During combat, if your movement speed and dodge speed are ten meters in an instant, then we will also quantify this speed of ‘ten meters in an instant’ as 1…”

"In terms of defense, we convert the amount of damage that can harm the body into our own defense, also represented by 1..."

"In this way, we can quickly obtain our own accurate data."

"The essence of 'data swordsmanship' is 'know yourself and know your enemy, and you will win every battle'."

"Once we have our own intelligence data, the next step is to gather intelligence data on the enemy..."

So, under the cherry blossom tree, Erin was speaking, and Rukia was listening attentively.

When Erin explained something Rukia didn't understand, he would pause and use examples from the Soul Society to deepen Rukia's understanding.

While giving her explanation, Erin didn't notice the passage of time.

Rukia, eager to strengthen herself, didn't notice the change in the weather.

During this time, Haruko Kuchiki came once. Seeing how engrossed Erin was in teaching Rukia, she didn't disturb him any further and went back to arrange for Toshiro Hitsugaya to stay.

"oops……"

Erin stretched and realized that he had unknowingly gone overtime in his teaching session.

He didn't really care, but he had already said enough today. If he continued, Rukia wouldn't be able to absorb and digest it, and it would just be a waste of time.

So Erin stood up and said to Rukia, "It's been so long since I've taught a student this carefully. I got so engrossed that it's almost dawn..."

"Next, Rukia, the first thing you need to do is successfully 'digitize' everything about yourself."

“Once you have completed your own ‘datafication,’ I will teach you the next step in the cultivation of ‘data swordsmanship’.”

"is teacher."

Although Rukia wanted to know more about "Data Kendo," she knew that after more than ten hours of intense study, she had reached her limit.

If you fully understand what the teacher said today, you will be able to truly embark on the path of "data swordsmanship" after completing your own "datafication".

……

With Aizen Sousuke, the Fifth Division Captain who was Erin in disguise, not causing trouble in Soul Society, Seireitei remained as peaceful as ever.

Occasionally, Erin would also take the time to give pointers to the Shinigami who had joined Aizen's ranks, helping them to steadily improve their strength.

In recent years, Erin has devoted most of his energy to Hueco Mundo.

After all, using the "Hogyoku" to increase one's spiritual pressure is easier to do in Hueco Mundo.

In Hueco Mundo, neither Nnoitra nor Szayelaporro dared to disregard Arryn's words.

The two scoured Hueco Mundo in search of a new Espada who could replace Neneel.

Finally, Neutra did indeed have a candidate in mind.

She was a female Vasto Lorde-class Hollow, so powerful that even Nnoitra had been defeated by her before she became an Arrancar.

However, this female Vastod did not kill Nnoitra, nor did she devour Nnoitra's body; instead, she spared Nnoitra.

……

Fifth day of intensive updates!

Chapter 208 Hao Libei

Now that Nnoitra has become an Arrancar, his strength has increased tenfold compared to before. He believes that if they meet again, he will definitely be able to defeat that guy.

This time, Neutra is determined to teach that guy what "survival of the fittest" really means!

……

Hueco Mundo, within Las Noches Palace.

After finishing today's training, Erin opened his eyes.

Beneath the throne, the 40th Espada, Ulquiorra, stood quietly, neither making a sound nor causing a disturbance.

"Lord Aizen."

Upon seeing Erin open his eyes, Ulquiorra bowed slightly and greeted Erin.

"It's Ulquiorra. You came to me on your own initiative. Have you found a suitable candidate for the Espada?"

"Yes, Aizen-sama."

"Oh?"

“Bring him up, Ulquiorra.”

"I'm very curious, what kind of being could possibly gain your approval?"

After receiving Erin's permission, Ulquiorra turned and left. Not long after, Ulquiorra returned with a giant caterpillar.

The moment Erin saw the caterpillar, he knew that this one was definitely the only Espada who could change his number after releasing his Zanpakuto.

The Tenth Espada, Yammy Rialgo!

"Hey, Ulquiorra, you brought me here just to see this Grim Reaper?"

The caterpillar followed Ulquiorra into Las Noches, and the moment it looked up and saw Erin, it was instantly enraged.

It raised its head high, making its body appear even larger.

"Yammy, this is Lord Aizen. You mustn't be so rude."

"Huh? Ulquiorra, you actually want me to call a Grim Reaper?"

Yammy lowered his head, glanced at Ulquiorra, and seeing that he made no move, Yammy became furious.

"Damn it, what exactly did you do to Ulquiorra?"

"Oh?"

When faced with Yammy's question, Erin chuckled.

"Why do you think I did something to Ulquiorra, instead of believing that Ulquiorra followed me willingly?"

"Is that even a question? You're a Shinigami, and we're Hollows. How could a Hollow willingly follow a Shinigami?"

"Shall we make a bet? If you still hold onto this idea after a while, I will give you a chance to fight me fairly and take Ulquiorra from my side."

"But if you change your mind, you must be unconditionally loyal to me and obey my orders, how about that?"

The reason Erin spoke to Yammie in this way was because Erin had some knowledge of Yammie.

This guy loves fighting and is particularly fond of killing.

Even though he no longer needed human souls as food or to evolve, he still used the ability of "soul absorption" to devour human souls on a large scale, causing great casualties in the mortal world.

But this guy has an advantage that none of the other Espada possess.

That is, Yammy Rialgo is the only Espada among the Espada who possesses the attribute of "loyalty".

Of course, it's not that Yammy particularly agrees with Aizen; it's just that Yammy is the kind of reckless man who would rather act than think, and once he has someone to serve, he won't even consider betraying them.
