Watching Cang Du leave in high spirits, the girls—other than Yoruichi—had huge question marks practically floating over their heads.
Rukia couldn't help asking, "Hey, Cole. What did you say you were going to teach him? Why did he get that happy?"
In terms of spiritual pressure alone, Cang Du's was noticeably stronger than the others. Even in the Seireitei, he'd be considered captain-class.
It was hard to imagine someone like that getting so excited from just one sentence.
"Well…" Cole scratched his head, a little exasperated. "You've seen the Blut I used before, right?"
"Blut?"
"The blue lines that appeared on your body?" Soi fong looked thoughtful.
When those blue patterns had appeared on Cole's skin, his defense had skyrocketed—his skin had become harder than a zanpakuto.
She'd wanted to ask back then, but one thing after another kept delaying it.
Unohana also recalled it.
Cole nodded and, without hiding anything, explained the principles behind Blut Vene (Static Blood Armor) and Blut Arterie (Flowing Blood Armor). He lifted his arm and said, "Because of Blut, my combat power increased by at least twenty to thirty percent."
The girls were immediately shocked.
Cole was already insanely strong, yet this Blut could still raise him by that much.
Unohana instinctively reached out, channeling a large amount of spiritual power through her body.
Soi fong and Rukia also looked eager to try—this kind of miraculous power was something they wanted to master too.
Yoruichi, lounging lazily, said, "You might as well give up. I've looked into this before. This isn't an ability Soul Reapers can learn."
Soul Reapers were dead souls. No matter what, it was impossible for them to channel spiritual power into blood vessels.
In other words—
This was an ability designed specifically for the living.
Unless Faux Body technology advanced to the point where Soul Reapers could possess true flesh bodies… but then they wouldn't really be Soul Reapers anymore.
Unohana and the others looked disappointed, but then they suddenly thought of something and stared at Cole nervously.
"Cole, if you give them an improved Blut, isn't that helping the enemy? What if they get stronger?"
Cole chuckled. "Honestly, if they can really learn it, I'll respect them."
As he spoke, he headed toward the training grounds.
The girls hurried after him, keeping their expressions cold while secretly taking in the scenery around them.
It really was a strange new experience.
The Invisible Empire's scenery was beautiful in its own way—there was a strong "foreign travel" vibe to it.
But when they reached the training grounds, they tensed immediately.
Because there were several powerful spiritual pressures gathered here.
"Legion Commander! Are you finally going to teach us those two improved techniques?!" Giselle Gewelle waved at Cole happily.
Bazz-B laughed loudly, waving with fanatic enthusiasm.
"Legion Commander, I won't disappoint you! Once I learn it, I'll help you go beat up Haschwalth!"
Since he and Jugram were "friends," betraying him came with zero psychological burden.
In fact, Bazz-B had wanted to beat Jugram up for a long time.
Meninas McAllon put her index finger to her lips and said innocently, "Legion Commander, I'll work hard too."
The others spoke up one after another, their eyes burning as they stared at Cole.
It wasn't surprising they were excited.
The Blut Cole had displayed was too powerful—powerful enough to make them so fired up they could barely sit still.
Even in the Invisible Empire, the law of the jungle still ruled.
It was even harsher than the Seireitei by dozens of times.
A Quincy who lost could very well be executed on the spot.
For example, a few hundred years ago, a Sternritter invaded Hueco Mundo and was crushed by an Adjuchas-class Hollow.
He barely escaped back alive…
Only to be judged as having "stained their honor" and executed on the spot in Silverframe City.
So in the Invisible Empire, the Quincy hunger for power was far greater than the Soul Reapers' in the Seireitei.
If they could master these two improved abilities, their strength would increase by at least thirty percent.
Under everyone's gaze, Cole's expression stayed cold as he told them to quiet down.
Instantly, the whole field fell silent.
In that atmosphere, Cole slowly displayed Blut Vene (Static Blood Armor) and Blut Arterie (Flowing Blood Armor), bringing out the blue patterns on his skin.
"Whether it's Blut Vene or Blut Arterie, in essence, it's a technique that compresses spiritual power into the blood vessels."
"It's just that Blut Vene, because it's 'static,' has a stronger compression than Blut Arterie."
"So what we need to think about is this: how do we fuse more spiritual power into the blood vessels without making them burst?"
The Quincy in the field looked like their eyes were glowing green.
Yes.
This was exactly what they wanted to know.
How in the world did Cole cram that much reishi into his blood vessels?
Were his blood vessels harder than steel?
Cole ignored their thirst and continued.
"I thought about this problem many years ago. I ran a lot of experiments. In the end, I turned my attention to the Soul Reapers…"
"Soul Reapers?!" The Quincy stared in shock.
They never expected this to have anything to do with Soul Reapers.
Seeing Cole speak so smoothly, the girls' expressions almost cracked. Soi fong whispered, "If I remember right… this brat is only sixteen."
Many years ago?
Were you researching this in diapers?
Rukia also wanted to laugh. Cole talking nonsense like this was weirdly entertaining.
Cole remained serious.
"That's right—Soul Reapers."
He covered his body with a dense layer of spiritual power.
"The reason Soul Reapers have such strong defense is because they use spiritual power like an exoskeleton, coating the outside of the body."
The Quincy looked thoughtful.
Then Cole smiled, drawing the spiritual power on his body back into himself.
"If that's the case, then why can't we coat the outside of our blood vessels with reishi and strengthen the blood vessels' defense?"
"At the end of the day, Quincy are the masters of reishi. We can dominate it like it's an extension of ourselves."
"Soul Reapers can't do that kind of delicate control, but Quincy are different—we can do micro-control down to the cellular level…"
Hearing Cole's "nonsense," the Quincy all sucked in a cold breath.
Cang Du even raised his arm, staring at the faint vessel outlines that seemed to surface beneath his skin. His voice turned hoarse.
"Coat blood vessels with reishi to reinforce them… can something that insane really be done?!"
Even with his "Steel" Schrift, he felt suffocated in that moment.
Because it sounded absurd.
Coating the outside of the body with spiritual power was crude and simple.
But blood vessels?
They were far too thin—especially the smallest capillaries. The slightest disturbance could make them rupture.
Trying to coat capillaries with reishi—
Was like using a thread thousands of times thinner than a hair to wrap a bacterium you couldn't even see with the naked eye.
The difficulty was hell-tier.
And even if you somehow could do it…
How many blood vessels did the human body have?
About twenty-five billion.
The combined length of arteries, veins, and capillaries could reach roughly one hundred thousand kilometers—enough to circle Earth's equator two and a half times.
Just imagining coating that much vasculature with reishi made your scalp go numb.
Even Cole felt a little horrified inside, but he still forced a stern expression.
"Only the weak think like that. If it couldn't be done, then what do you think my fused Blut Vene and Blut Arterie are?"
The Sternritter all stared at each other, looking like they were about to cry.
How did you do it?!
We can't do it!
We're Quincy, not reincarnated microscopes!
Then Bazz-B suddenly seemed to realize something. He looked at Cole in delight.
"Legion Commander, I get it! You mean we should advance step by step—starting with the main arteries first, right?"
Cole froze for a moment.
And after hearing that, Cang Du's eyes lit up as well.
"Right! We don't have to coat every vessel from the start. We can begin with the largest arteries, then gradually extend into the veins!"
After Cang Du said it, the others also understood.
"Yeah, capillaries are way too fine—but arteries are different. That actually might be possible…"
"We can start with the largest arteries. If we succeed, our strength will already rise…"
"Right. Even if the power of Blut Vene is hard to change, Blut Arterie will definitely increase a lot…"
"Start with arteries, gain experience, then extend to veins, and only then try capillaries…"
The Sternritter got excited.
They didn't even need Cole to explain anymore.
After a short exchange and some brainstorming, they'd already come up with several "workable" plans.
Meninas lifted her head, looking at Cole with admiration.
"Legion Commander, you're amazing. You even thought of something like this. We never would've dared imagine such a dangerous method."
Cole's mouth twitched. He turned his head away and coughed a few times.
"Exactly. That's what I meant. Not bad—you do have some talent, managing to figure it out yourselves."
Rukia and the others had dark lines on their foreheads.
Sure, different fields were different worlds.
They didn't really understand Blut Vene and Blut Arterie.
But they understood Cole's reaction perfectly.
This sixteen-year-old high schooler was absolutely bluffing.
It was just that—
His bluff somehow became a prophecy.
If these guys really researched something out of it…
