Bu in Kyoya's eyes, this thing that can kill people is actually an item that could increase his training efficiency?
Was this even human logic?
However, as unbelievable as it sounded, Kisuke didn't doubt Kyoya's words.
Having once witnessed Kyoya smash a Sekkiseki Mine with his bare hands in the Rukongai, Kisuke was one of the few in the Seireitei who knew the extent of Kyoya's monstrous physical prowess.
And according to Kyoya himself, he hadn't even reached his peak yet…
Kisuke glanced at Kyoya and suddenly understood.
He had forgotten that, although Kyoya had been the Captain of the 11th Division for over a decade, Kyoya himself was still a 'boy' under thirty years old.
For a Shinigami, this period was indeed the stage of fastest growth.
"I understand, Captain Kyoya."
At that moment, Kisuke said, "I'll look into the progress of the gravity device research as soon as possible and do my best to complete its development in the shortest time possible."
That said, Kisuke wasn't doing this just for Kyoya.
From Kyoya's description alone, the gravity device was undoubtedly an excellent training aid.
Especially for Shunpo training, it would have a significant boosting effect.
Even if others couldn't train under ten times gravity like Kyoya, practicing in two or three times gravity would still greatly improve their efficiency.
Once they returned to normal gravity, their speed would see a qualitative leap.
Moreover, under higher gravity, a Shinigami's spiritual body could also be tempered, increasing their physical strength and allowing them to contain more Reishi… directly enhancing their combat power.
"Captain Urahara, how long do you estimate it'll take to complete the gravity device?"
"W-Well…"
Kisuke pondered for a moment, "Around fifty to a hundred years, I'd say."
Though he wanted to finish the research left behind by Kirio quickly, Urahara also had his own projects to work on. He couldn't possibly devote all his energy to this.
If not for not wanting to let Yoruichi break her promise to Kirio, Kisuke, who was far from a people-pleaser, wouldn't have bothered entertaining someone like Hiyori.
"Too long."
Kyoya shook his head.
'Fifty years? Even Charlotte Linlin became one of the Four Emperors in less than fifty years.'
While Shinigami lifespans were different from those in the One Piece World. In One Piece World, aside from the Five Elders and Imu, most people lived no longer than a century, and the oldest known person was Dr. Kureha of Drum Island, who is currently 141 years old.
But Shinigami?
For Captain-level Shinigami, unless something unexpected happened, a thousand years was nothing.
Yamamoto, for instance, was already over three thousand years old.
Fifty years might seem like nothing to other Shinigami.
But Kyoya, having lived two lifetimes combined, was only around that age. And now that Kisuke had become the captain of the 12th Division, Kyoya had no intention of waiting fifty years.
If he couldn't fully unlock the potential of his Steel Balloon Physique, Kyoya would feel like he was wasting his luck.
That's right… in Kyoya's view, the value of the Steel Balloon Physique far surpassed that of the three types of Haki.
Unlocking Haki required long, arduous training.
But the Steel Balloon, an invincible physique, was something that placed its wielder at the pinnacle of the world from birth.
Even after Charlotte Linlin gave birth to over eighty children, draining her vitality, she still remained one of the Four Emperors!
Yet, with Kyoya's current physical strength, ordinary training barely did anything for him.
"How about this, Captain Urahara."
"Please put a little more effort into the gravity device."
"For now, could you make me some weighted training equipment?"
"Things like wrist weights, leg weights, a weighted vest, and so on."
Hearing Kyoya's words, Kisuke stroked his chin.
Admittedly, Kyoya's mind worked fast.
Though weighted gear couldn't compare to a gravity device, until the latter was completed, weights were indeed the most cost-effective and suitable alternative.
"If it's just about weight..."
"Three days. At most, three days, and I can finish them."
After some mental calculations, Kisuke gave Kyoya his answer.
"Three days? Not bad."
Kyoya nodded in satisfaction.
He knew Urahara's capabilities.
If even something as simple as weighted gear took Urahara too long, Kyoya might just have to give him a little 'musclehead shock therapy'.
"Oh, and Captain Urahara, don't worry about whether I can handle it or not. Just make it as heavy as you possibly can."
"Understood."
Kisuke nodded.
Who is he joking?
Someone who could smash a Sekkiseki mine bare-handed was hardly someone he needed to worry about being crushed by the weights he made. What he should be worried about was whether, if he failed to meet Kyoya's expectations, this guy might decide to train inside the 12th Division's barracks.
Judging by the sheer scale of Kyoya's training sessions, the 12th Division wouldn't survive the aftermath...
Three days meant three days!
Seeing Kyoya blocking the entrance of the 12th Division, Kisuke felt a surge of relief.
Thankfully, his Bankai was more than capable enough to produce the heaviest metal he could possibly create.
Otherwise, if he hadn't finished Kyoya's weighted gear today, he might not have even made it out of the 12th Division's front gate.
"Hahaha, Captain Kyoya, I was just about to go look for you."
"Is my gear ready?"
"Yes."
Kisuke nodded, "However, Captain Kyoya, once this thing was completed, even I couldn't move it."
"So, you'll have to retrieve it yourself."
"Perfect."
Hearing what Kisuke said, Kyoya grinned: "Then lead the way. I can't wait to put this thing on."
Under Kisuke's guidance, Kyoya arrived at a laboratory.
At the center of the lab lay a black Shihakusho.
The ground around it was cracked and sunken, as if it had collapsed under the sheer weight of the Shihakusho.
"This is it."
Kisuke rubbed his temples and said, "This thing is made of the heaviest metal I can make at the moment."
"I used a total of 0.5 cubic meters of osmium to make this."
"In terms of weight alone, it comes out to 11.25 tons."
"Very good."
Kyoya was even more pleased hearing this.
11.25 tons… that was 11,250 kilograms.
His current body, enhanced by both Kuma's bloodline and Big Mom's constitution, weighed a staggering 96 kilograms despite only being just over 160 cm tall.
A Shihakusho weighing over ten thousand kilograms was roughly equivalent to Kyoya training under over a hundred times normal gravity.
'No wonder he said that even he couldn't lift the thing once it was finished.'
Kyoya stepped forward and reached out, gripping the black Shihakusho.
"Not bad!"
Feeling the weight in his hands, Kyoya's excitement grew.
He exerted force, slowly lifting the weighted uniform.
Crack… creak…
As the Shihakusho gradually rose, its weight shifted onto Kyoya's body, causing his feet to sink into the ground. Tiny fissures spread outward from beneath him.
'Is this guy even human?'
Even though he had expected this, Kisuke's eyes still widened in disbelief.
If he had to destroy a ten-ton boulder, Kisuke could easily manage it… whether with Kido or a slash from his Zanpakuto, but lifting something this heavy with pure physical strength, like Kyoya was doing now?
Kisuke shook his head, deciding not to dwell on it.
Still, his curiosity about Kyoya deepened.
Kyoya was a genius… that much was acknowledged by every Shinigami in the Gotei 13.
The sheer skill required to unleash Kenatsu purely through Zanjutsu was something only a handful in the entire Gotei 13 could replicate.
But from what Kisuke understood, 'genius' was only one aspect of Kyoya.
Kyoya's body was even more astonishing than his Zanjutsu.
Three days ago, when Kyoya had caught Hiyori's Zanpakuto bare-handed, Kisuke had been plenty shocked.
But compared to this, Kyoya's feat three days ago seemed like nothing.
Without hesitation, Kyoya removed his Captain's Haori and regular Shihakusho, then slowly donned the weighted uniform before draping the Captain's Haori back over it.
"Not bad."
Feeling the pressure coming from his body, Kyoya was satisfied.
After walking a few laps around the lab, Kyoya finally adjusted to the suit's weight. Using Life Return, he fine-tuned his body to counteract the load… keeping himself in a constant state of training while ensuring he didn't crack the floor with every step. Two birds with one stone.
"However, Captain Urahara, I estimate this suit hasn't reached my limit yet."
"Next, I'd like you to make another one just like it."
"For the design, model it after a standard division Captain's Haori."
"Sure, no problem."
"You can come back in three days, Captain Kyoya."
"Thanks, Captain Urahara."
"Once the gravity training equipment is ready too, I'll owe you a favor."
With one training hurdle cleared, Kyoya felt a weight lift from his mind… figuratively, at least.
Whether it was weighted gear or gravity devices, both would enhance his training efficiency.
That would significantly cut down on his required training time.
After all, unlike the instant mastery granted by achievement rewards, progress in the Bleach World demanded real, sweat-and-blood effort… every punch, every slash, earned through sheer repetition.
