Death: Then stood in the sky.

"Is this the kind of medicine you researched that can unleash power exceeding one's spiritual pressure limit in a short period of time, but has the side effect of causing weakness for a period of time after the effects wear off?" Unohana Retsu's eyes showed a hint of surprise. Although she had known about the existence of this medicine for a long time, this was the first time she had seen it in person.

Aoshi nodded.

"Then I'll accept it." Unohana Retsu said succinctly, about to put the medicine away.

But a hand pressed down on hers, stopping her from moving.

Unohana Retsu was somewhat puzzled.

Aoshi: "This is the upgraded version."

Upon hearing this, Unohana frowned deeply.

Aoshi continued, "There are no side effects."

Unohana Retsu's gaze suddenly sharpened.

Is it possible to unleash power exceeding one's spiritual pressure limit in a short period of time without any side effects?

Has Aoji's R&D capabilities really reached this level?

But... that's not all.

Aoji further explained: "And its effect is no longer to unleash power exceeding one's own spiritual pressure limit in a short period of time, but rather to break through one's own limits to a certain extent and increase spiritual pressure slightly."

Qing Si enunciated each word clearly: "Permanent."

This time, Aoji finally saw a look of disbelief on Unohana Retsu's face. Her eyes were filled with shock and disbelief, and she lost control of her emotions on the spot.

Aoshi looked completely satisfied.

That was awesome!

It's already incredible that Unohana Retsu could break down her expression to a certain extent, considering she's the greatest female genius and the greatest villain in a thousand years.

Even when facing Aizen, who instantly killed Toshiro Hitsugaya, he always maintained a gentle, smiling demeanor.

More breakdowns are only available to VIP members; they can be described here, but there's no need to.

Aoji's gaze was fixed on the medicine.

This is a new spiritual pressure amplification potion that Aoji obtained after fusing with the Hogyoku, using his own blood and the power of the Hogyoku as materials, and mixing it with various rare materials. It has been officially renamed the Weak Spiritual Pressure Limit Breaking Potion.

The drug's effects are also simple and direct.

Break the limits of death!

【Name: Weakened Spiritual Pressure Limit Breaking Drug】

[Attribute: After use, it can forcibly increase one's spiritual pressure slightly, regardless of one's own spiritual pressure limit, based on one's own talent and potential, without any side effects.]

[Note: Due to material limitations, we can only push the limits to a limited extent, but you have found a whole new limit.]

Chapter 13 Woman, Your Aggressiveness Is Too Strong

Death has its limits.

Once the so-called limit of spiritual pressure is reached, even the strongest Shinigami, no matter how outstanding their talent, will not make any further progress.

That was the strongest Shinigami of the millennium, Captain-Commander Yamamoto Genryusai Shigekuni.

As a fellow Grim Reaper who has reached almost the same limit, Unohana Retsu understands the authority of this conclusion better than anyone else.

As for ways to break the limits of the Grim Reaper's power... there are actually ways.

but......

“You are touching the power of Hollowfication.” Retsu Unohana’s gentle expression vanished completely, and her gaze toward Seiji became aggressive, instantly activating her battle stance.

If Aoji really touches that dangerous power, she doesn't mind taking a moment to make him realize that he shouldn't touch that thing.

"Hey, hey, don't spread rumors!" Aoshi almost pointed at someone like a husky, explaining, "Yes, but no."

There is generally only one way for Death to break through the limits.

That is—virtualization.

However, Hollowfication is a power that is strictly forbidden by the 46 Chambers, and no Shinigami is allowed to touch it. Violators will be considered traitors to Soul Society.

It's not that the 46th Chamber is heartless, but rather that the process of becoming a Voidling is far too dangerous, with a survival rate so low as to be negligible. Once the Voidling fails, it is completely irreversible, and one can only become a true monster.

The one that "Unohana Retsu" is referring to is clearly this.

Decades ago, a scandal occurred in the Soul Society that could be considered a major event for nearly a thousand years.

That is, several captains and vice-captains became ethereal monsters.

This includes the former 5th Division Captain Hirako Shinji with the watermelon head, the extremely strong but talkative former 3rd Division Captain Rojuro Horibashi who likes to tell others about his weaknesses, and the former 7th Division Captain Aikawa Raobu who has little presence.

And finally, the main attraction: Kensei Muguruma, who possesses titles such as the Soul King's Pocket Watch and the Shinigami's power level measurement unit.

Even captain-level Shinigami can't withstand the corrosive effects of Hollowfication and can't break through their own limits by mastering the power of Hollowfication, so you can imagine how dangerous this process is.

“This [Weak Spiritual Pressure Limit Breaking Potion] is not the same as the Hollowfication essence you understand.” Aoshi pointed to the sealed potion that emitted a faint blue-purple light: “Although I did mix in some Hollow power, it has been completely neutralized.”

To be precise, it was optimized through alchemy, perfectly combining with the power of the Hogyoku and Aoji's own blood.

Unohana Retsu lowered her eyes, as if she had realized something.

She gently shook the potion, and its ingredients seemed to be stimulated by her action, suddenly becoming active and bursting with a brighter glow.

It feels...like it's alive?

"How long will it take to take effect?"

"In an instant."

"Help me guard the door and don't let anyone in."

"it is good."

After a brief exchange, Retsu Unohana tilted her head back and drank the entire vial of medicine.

It's thick and concentrated, but not fishy.

Her pale throat bobbed as she swallowed.

A few seconds later, although she already knew the effects of the drug and completely trusted Aoji and was not worried that he was deceiving her, Unohana Retsu still showed a look of astonishment.

Her spiritual pressure is really rising!

Furthermore, because Shinigami are highly aggregated forms of pure spiritual pressure, the increase in spiritual pressure also brings about a comprehensive improvement in physical qualities.

Strength, speed, stamina, and defense.

All attributes related to physical qualities benefit from the increase in spiritual pressure.

This medicine?!

It actually can increase the spiritual pressure of the Shinigami, and there are no side effects!

"How many people know this?" In the instant her reason returned, Retsu Unohana's gaze fell on Seiji, her eyes filled with icy coldness.

No, are you that aggressive?

Aoshi knew that this sudden outburst of murderous intent was not directed at him, but that precisely illustrated the problem.

Unohana Retsu had the idea of ​​helping her clean up the mess.

Aoji had no doubt that if he simply uttered a few names, Unohana Retsu, the greatest villain of a thousand years, would go and kill him.

"Commander-in-Chief Yamamoto."

"???"

"Ahem, just kidding."

Having nearly been beaten, Qing Si's expression turned serious: "You, and me."

That's it?

"That's all."

A smile appeared in Retsu Unohana's eyes as she crushed the opened container in her hand and nodded to Seiji.

Aoshi placed his thumb on the hilt of the Zanpakuto and slightly drew it from its sheath.

next second.

The sudden burst of lightning reduced everything to ashes, leaving no trace.

It was lightning?

Noticing this, Retsu Unohana said, "Your mastery of the Zanpakuto has deepened."

Seiji: "Compared to a Zanpakuto, I actually prefer..."

Unohana Retsu flashed a business-like smile: "No, you don't want to."

Hey woman, what's wrong with me thinking? Is thinking a crime?

I just want to, I'm determined to think about it, I not only want to think about it, I'll dream about it tonight...

Retsu Unohana probably knew that Seiji was thinking dirty thoughts. Although she had no evidence, she didn't need evidence. She narrowed her eyes and said, "You'll get a beating."

How could you say such vicious things with such a gentle appearance, woman?

Aoji gave in.

It is beyond repair.

Wait until I get my hands on Kisuke Urahara... no, I mean, I'll get my hands on the Hogyoku from Kisuke Urahara's body.

"Don't tell anyone about this drug that breaks your spiritual pressure limits," Retsu Unohana earnestly reminded Seiji, "not even the Captain-Commander."

It's not that Captain-Commander Yamamoto is untrustworthy, but rather that Seireitei and the 46th Chamber are untrustworthy.

Once this drug that allows Shinigami to transcend all risks and side effects is exposed, it's unimaginable how much shock and trouble it will cause throughout Soul Society.

After giving these instructions, Retsu Unohana finally asked a question that concerned herself: "Can it be used multiple times?"

She still cares so much about fighting.

Aoshi gave an obvious conclusion: "No, it can only take effect once, and using it more often will not produce any more effects."

Unohana nodded, as expected.

This thing has such a terrifying effect that it can help Shinigami break through limits and increase spiritual pressure. It would be truly exaggerated if it could be used infinitely.

but......

Retsu Unohana asked again, "Since it's a weak type, then there must be other types, right?"

Qing Si shrugged.

They're as vigilant as ever.

I knew she would notice the word "weak" that I mentioned.

"Yes, but due to material limitations, I can't make it for the time being, and even the weak spiritual pressure limit-breaking drug can't be mass-produced."

Blood, Qing Si has no shortage of, one gold for ten blood, rounded up to the nearest whole number.

But what fused with Aoshi was just a flawed and cracked Hogyoku that wasn't even a half-finished product. It had to help him repair his body, increase his spiritual pressure, and evolve, and it also had to spare some for him to experiment with. Even cattle and horses don't use it like this.

Aside from Rangiku's hair, the other materials are also uncommon.

For example, the spiritual pressure and mask of the Great Void.

It's very difficult to obtain these materials if you stay in Soul Society.

After saying goodbye to Retsu Unohana, Seiji returned to the 13th Division and received a message from Kaien Shiba.

Rukia Kuchiki has joined the 13th Division.
