Demon Slayer: The Journey That Began When I Became Yoriichi's Sister

Chapter 588 The Weaknesses of Instantaneous Strike

"..." The atmosphere was silent for a moment before Yoruichi's voice rang out softly, "Is there any connection between the two?"

Yuko explained in a serious tone, "This means I can concentrate on my thoughts."

Yoruichi was stunned by her twisted logic, which seemed to make some sense, but not much.

Yuko continued, "If I want, I can generate multiple brains in my body to process more information."

Recalling his sister's previous instructions, Yushiro suppressed the urge to delve deeper.

What does it mean to generate multiple brains within the body?

Is it the literal meaning?

Is this something Death can do?

He seemed to have only heard of such methods from Hollows; he had never heard of a Shinigami being able to generate multiple organs within their own body. Even the Zanpakuto's ability was far too bizarre.

Yoruichi gave a thumbs-up in admiration: "That sounds a bit disgusting, please don't say it."

Yuko's lips twitched, which is why she didn't do that.

After exchanging a few casual words, Yoruichi steered the conversation back on track: "What did you mean by the circulation of spiritual energy within my body?"

“Hmm~” Yu Zi pondered for a moment, then innocently raised her head, “I’m actually not quite sure either.”

"……what?"

Veins bulged on Yoruichi's forehead.

Is this some kind of joke?

Seeing this, Yu Zi quickly added, "I'm just not sure. If I could watch it again, it should be about right."

Yoru's eyelid twitched: "Almost what?"

"You should be able to understand the principle by now."

Yoruichi raised an eyebrow and narrowed her eyes slightly: "Understand...the principle?"

Yu Zi replied straightforwardly, "It's meant to be used."

"So arrogant?" Yoruichi gasped. Was this idiot really that shocking?

Although she understood that the so-called transparent world allowed Yuko to see the movement of spiritual particles within the soul, if she only saw it a few times and knew the principle, and then wanted to use it, wouldn't the Shunko, which she had painstakingly developed but had not yet, seem too useless?

Let's keep things separate. You don't see many people becoming mathematicians just because they know a formula.

Yoruichi was quite confident in her abilities.

Yu Zi paused for a moment, then asked, "Arrogant? Is it arrogant?"

"Isn't that cool?" Yoruichi raised her eyebrows even higher.

Yushiro stood aside, awkwardly laughing. The interaction between the two was still as amusing as ever.

"Fine, I'll see what kind of mess you're up to." Yoruichi crossed her arms. "You've been a teacher for a few days and you're already thinking of instructing me."

Yu Zi did not respond, but instead carefully put away the exaggeratedly long scroll.

She stood up, clapped her hands, and said to Yoruichi, "Then after dinner, we'll go to the training ground..."

"Why are you still eating? Come with me!" Before she finished speaking, Yoruichi pulled her towards the dojo.

Inside the dojo.

Yoruichi stood in the center of the dojo, took a deep breath, placed her hands in front of her in a Hakuda stance, and her spiritual pressure began to rise rapidly.

"Look closely, Yuko!"

With a low shout, Yoruichi's surging spiritual pressure suddenly erupted. The highly concentrated Kido was wrapped around her back and shoulders, and the explosive spiritual pressure even tore the clothes on her back apart, with faint sparks of lightning spiritual pressure splashing out.

The terrifying captain-level spiritual pressure swept across the dojo, causing Yushiro's heart to skip a beat. Although he had witnessed the two fight countless times, he still found it difficult to withstand the suppressive power of the spiritual pressure.

Wow, you two are really amazing!

The turbulent spiritual pressure created a strong gust of wind that whipped Yuuko's white hair, and her golden eyes flickered with several streaks of light. In her vision, Yoruichi's body became a semi-transparent outline. Her skin, muscles, bones, and even internal organs were clearly visible.

As it turns out, having X-ray vision isn't anything special.

Being able to see through clothes is a skill; seeing through too much is like X-rays, which are completely imperceptible.

Yuko calmly watched the flow of spiritual energy within the Night Body.

As far as she knew, all matter in the mortal world was made of particles, while everything in the Soul Society, or rather the Shinigami, was made of spirit particles, whether it was the Shinigami's body or anything else.

In her view, the power of the Grim Reaper is the power of spiritual pressure.

Zanpakuto, Kido, Shunpo—these abilities all highly depend on the intensity of spiritual pressure, or in other words, the intensity of spiritual particles. The higher the level of spiritual pressure, the higher the density of spiritual particles.

The principle of Shunko is to enhance the destructive power of the technique by combining Hakuda and Kido, but in the end it is still related to the operation of spirit particles.

In her Shunko state, Yoruichi was filled with explosive fighting power, her frenzied spiritual particles filling the entire dojo, and golden lightning spiritual pressure gradually being guided from her back and shoulders to her limbs.

Yuko stared at Yoruichi without saying a word, her left hand resting on her right, her right hand against her chin, occasionally frowning.

Time passed second by second, and the spiritual pressure within Yoruichi began to become unbearable under the intense stimulation and started to become disordered.

Cold sweat began to bead on Yoruichi's forehead, and she couldn't help but ask, "Did you understand?"

She's about to give up!

But in front of Yuko, she would never admit that she was incapable.

Yu Zi snapped out of her daze and nodded: "More or less."

Yoruichi breathed a sigh of relief, deactivated her Shunho form, and walked towards Yuuko: "How was it, Yuuko-sensei? Did you understand the principle of Shunho?"

Look at this guy, he actually dares to give me instructions.

Yuko still frowned, seemingly deep in thought: "The general direction should be correct."

It must be said that Yoruichi's development of the Shunko ability was ingenious, combining Hakuda and Kido to unleash a combat ability far exceeding that of either.

Yoruichi nodded with a look of satisfaction, thinking that at least this guy knew how to say nice things.

Before Yoruichi could even feel happy for two seconds, Ikuko said, "However, it's still a bit rough around the edges."

As time goes on, spiritual pressure will gradually become out of control.

This is not to say that Yoruichi's control over spiritual pressure is poor, but rather that the combination of Hakuda and Kido is not yet perfect.

"Rough?" Yoruichi's face darkened; she had expected at least a slightly better review.

How could you say it's rough?

This is a skill she developed!

Provocation! Utter provocation!

This is intolerable!

Seeing that Yoruichi was about to explode, Yuko quickly raised her hand to interrupt: "Don't be angry."

Yoruichi's face darkened: "Do I look angry?"

“It’s not like…” Yu Zi paused, then changed the subject, “Let’s get back to the point.”

"The principle and use of Instant Harshness is a powerful combat enhancement ability, but the current situation is that you can't use this ability for a long time. You could even say that it's only in its rudimentary stage, and even the power of the enhancement is quite limited."

"I think the explosive power and intensity of Instant Roar can be further improved."

Yoruichi paused for a moment, then raised an eyebrow: "Not bad, you actually figured it out."

"Indeed, the current development of Instantaneous Strike has not yet met my expectations, especially in terms of burst strength."

Yoruichi wasn't really worried about the length of time she would use it.

Sometimes, a special skill can turn the tide in an instant, and she is confident that she can perfect it over time.

However, in terms of explosive power, it did not meet her expectations at all, and she didn't even have a clue how to improve it.

Yoruichi teased, "What? Does Professor Yuuko know how to improve this?"

Yuko is indeed very talented, but she still doesn't quite believe it. Understanding something and being able to use it and improve upon it are two different things.

Yuko didn't respond immediately. Instead, she walked to the center of the field while pondering something, making a gesture of ignoring the challenge.

Yuko closed her eyes slightly, recalling how the spiritual particles within her body operated when Yoruichi entered the Shunko state.

Yushiro looked shocked: "Could it be..."

Yoruichi's expression also turned serious.

Yuko murmured with her eyes closed, "I remember... this is how spirit particles should work."

She hadn't actually studied Kido systematically, but Yoruichi and Kisuke Urahara had demonstrated some Kido techniques to her when they first introduced her to spiritual pressure.

Yuko has also successfully used a low-numbered Kido.

As for fighting for free... how could you not know how to do that?

In the game "Zanken Zouki," Yuko's strongest skill is currently Zanken, which is based on hand-to-hand combat and swordsmanship.

Yuko can be considered a master in this regard.

“First, my back and shoulders…” Yuko closed her eyes tightly, slowly exhaled a long breath, and controlled the movement of her spiritual particles according to the details she had seen from Yoruichi.

Using the body to withstand the first step of combining Hakuda and Kido is a very clever idea; it would be difficult to spread it directly to the limbs.

A faint crimson spiritual pressure poured out from Yuko's body and spread instantly.

Yoruichi frowned slightly. This was the first time she had seen Yuuko's spiritual pressure leaking out. Previously, Yuuko's control over her spiritual pressure was basically limited to the use of her Zanpakuto and the internal enhancement of her physical abilities.

The reason she frowned was that although spiritual pressure does not have an absolute attribute difference, everyone's spiritual pressure expression is definitely different. For example, when her spiritual pressure is combined with the Kido, it takes the form of golden lightning.

This is especially evident in Shinigami whose Zanpakuto are elemental, such as fire element flames, ice element cold air, lightning element golden light, and so on.

Logically speaking, the performance of a Zanpakuto should be consistent with the performance of spiritual pressure.

When Yuuko's Zanpakuto was partially released, it displayed a colorful rainbow light, but when it was fully released, its Shikai state was blue-purple, which can be roughly regarded as dark purple, and the spiritual pressure slashes it released were also dark purple.

Her spiritual pressure should also be a dark purple, but Yuko's spiritual pressure is currently showing a faint red.

Before Yoruichi could continue pondering, Ikuko had already found a balance between the spiritual pressure of combining Hakuda and Kido.

boom! !

A solid spiritual pressure suddenly erupted, and the crimson spiritual pressure exploded on her back. Her black Shinigami armor was damaged for a moment, but was immediately covered and concealed by Yuko's flesh and blood.

The solid crimson spiritual pressure coiled around Yuko's body like lightning, crackling and popping.

Yoruichi's face showed shock; she had actually done it.

Having only witnessed the instant-coaxing state a few times, and without even her guidance, he learned how to use it on his own.

As the captain of the Second Division and the head of the Shihouin family, Yoruichi always had some doubts about Ikuko's existence.

That is, is Yuuko really an existence called a demon, as she claims?

The so-called spiritual pressure level was actually deliberately concealed; otherwise, it would be too exaggerated to raise a spiritual pressure level from over ten to captain level in just one month.

While the initial release state can indeed increase spiritual pressure level, the magnitude of your increase is simply unheard of.

Although Yoruichi had a very good impression of Ikuko, he did have this thought in his heart.

But now, that last bit of doubt in her mind has been completely dispelled.

The instant coaxing technique was developed by her, and only Kisuke knew about it, and that was all.

Yoruichi was confident that even with her personal instruction, this was definitely not something that could be mastered in less than two months, let alone just by glancing at it a few times.

But then again, doesn't this just prove one thing?

Could this guy really be a genius?!

Damn it! Why does she feel so defeated?!

Yushiro was so shocked that he couldn't speak.

Yu Zi is amazing! Is there anything Yu Zi can't do?

Yoruichi put aside her distracting thoughts and carefully observed Yuuko's condition, clicking her tongue in amazement, "You really can't be judged by common sense."

"The stability of this spiritual pressure seems to be even better than mine."

Yoruichi was somewhat impressed; not only had they completely replicated Shunko, but they had even managed to make it more stable.

"how did you do it?"

"Regarding that, it's simply that my control over spiritual pressure is currently more stable than yours."

hateful!

Yoruichi gritted her teeth, unable to find a reason to refute him. This guy is just too over-the-top!

"And then it should be..." Enveloped in crimson lightning-like spiritual pressure, Yuko appeared very calm. She clearly sensed the flow of spiritual particles within her body and began to tentatively apply stimulation.

Gradually spread the spiritual energy to the limbs, then stimulate them with the power techniques of the Kido, focusing on the intensity of the applied spiritual pressure.

Yoruichi probably tried it too, but after increasing her spiritual pressure, Shunho's state couldn't be stabilized, and it might even have the opposite effect, so she limited Shunho's burst to a lower level.

This is like an uncontrollable bomb; it not only fails to help but can easily injure you.

But Yuko is different. Her understanding of the world and absolute control over her own body allow her to perfectly control the flow of spiritual particles within her body.

If we compare spirit particles to blood, Yuuko can maximize the flow of blood through the body's meridians, while Yoruichi cannot.

Just like a water pipe, the greater the water pressure applied, the higher the requirements for the pipe. However, if the water state tends to be stable, even with strong stimulation, it can be quickly connected without worrying about damaging the pipe.

At least... there should be absolutely no problem in the short term.

All that remains is to gradually improve the stability of the spiritual pressure when combining Hakuda and Kido.
