At this time, although Renji couldn't stomp the ground dozens of times in an instant, he could manage four or five times.
Because of this, Renji's running speed was two to three times faster than before.
However, correspondingly, Renji's physical stamina consumption also increased exponentially.
Coupled with the weights Renji was wearing, his consumption became even greater.
In fact, if Renji removed his weights to practice [Soru], his training speed would be faster.
But, Kyoya had told Renji that if he practiced while wearing weights, once he mastered it, with the same number of stomps, the explosive power he could unleash would be several times greater than if he practiced without weights.
Furthermore, while the Rokushiki are combat techniques, they are also physical training methods.
The process of practicing the Rokushiki is also a process of training the physique.
Anyone who has trained with weights knows how effective it is.
If Renji had high demands for his own future, he naturally wouldn't do such a 'shortcut' thing.
On the other hand, after instructing Hitsugaya, Kyoya came to the playground and saw the students training.
It wasn't just Renji who was working hard… the other students without Reiatsu were also putting in effort.
However, compared to Renji, the others fell short not just by a little, whether in training volume or intensity.
There was nothing even Kyoya could do about this point.
Not to mention the gap brought by Reiatsu, just in terms of physical talent, Renji was above the other twelve students in the class without Reiryoku.
In Kyoya's view, by the time they reached sixth grade, most of the other twelve students would probably only be able to learn Soru, with a small minority learning two or three of the Rokushiki techniques.
After graduation, they might pass the Baltigo Academy's assessment and qualify to join the Revolutionary Army.
As for Renji, he could at least complete the training of the Rokushiki, and his strength would be considered elite even among the soldiers of the Revolutionary Army.
Moreover, if Renji's talent was sufficient and his training diligent enough, it wasn't impossible for him to comprehend one or two 'secret techniques' of the Rokushiki, allowing his strength to reach the cadre-level of the Revolutionary Army.
The cadres of the Revolutionary Army are powerful individuals capable of rivaling the seated officers of the Gotei 13.
So far, the number of cadres in the Revolutionary Army hasn't exceeded a hundred.
Most of them are former members of the 11th Division who left the Seireitei with Kyoya over twenty years ago.
In the Bleach World, the upper limit for ordinary people is just too low.
No!
Actually, it's not just the world of Bleach.
Even in the One Piece World, Naruto World, and many other 2D Worlds, the upper limit for ordinary people is pitifully low.
The protagonist of One Piece, Luffy, has a grandfather who is a Marine Hero, a father who is the leader of the Revolutionary Army, and two brothers: one is a division commander under the world's strongest man, Whitebeard, and the other is the second-in-command of the Revolutionary Army.
The one who led Luffy onto the path of a pirate was Red-Haired Shanks, one of the Four Emperors.
The Devil Fruit he ate is the [Sun God] Nika.
As for the protagonist of the Naruto World, his father was a Hokage, his mother was the Jinchuriki of the strongest Tailed Beast, the Nine-Tails, and his teacher is a legend...
Meanwhile, for the protagonist of the Bleach World, his father is the head of the Shiba Clan's branch, one of the oldest noble families in the Seireitei, his mother is a Quincy, and he also possesses the power of White, a Hollow created by Aizen using a fragment of the Soul King's power...
It can be said that Ichigo was born as the Soul King, possessing Shinigami power, Hollow power, Quincy power, and Fullbring power!
One can only say that the Japanese's Anime Worlds are really very unfriendly to ordinary people.
If Kyoya didn't possess the [One Piece Achievement System], which allowed him to gain power from the One Piece World by achieving certain accomplishments, then Kyoya would have, at most, become a seated officer in one of the Gotei 13's divisions in the future.
Forget the Thousand-Year Blood War… Kyoya wouldn't even have much confidence in whether he could survive the battles between ordinary Shinigami and Hollows.
After all, even in peaceful times, the casualty rate among the Shinigami of the Gotei 13 is not small.
Especially the Shinigami of the 13th Division stationed in the living world… if they encounter a powerful enemy and can't hold out until reinforcements arrive, they truly have no choice but to die in the line of duty.
Probably only after Aizen completed his rule over Hueco Mundo, using most of the Menos Grande as experimental subjects, did the Menos Grande disappear from the living world, making the task of the 13th Division's Shinigami stationed in the living world relatively safe.
Otherwise, Byakuya wouldn't have allowed Rukia to not serve as a seated officer of the 13th Division, but instead go to the living world as an ordinary Shinigami for station duty.
Shaking his head, Kyoya pressed down the thoughts in his mind and stopped watching the training of Renji and the others, turning to leave.
From their training, Kyoya knew that both the other twelve students and Renji needed a certain amount of time to complete the training content he had previously assigned them.
Barring any accidents, he now had about a month of free time.
'Well, then, let's go take a look at the other classes!'
Since he had decided to stay at Baltigo Academy for a few years, it didn't make sense to devote all his time to the children in the class without Reiryoku.
He should also occasionally go and provide guidance to the other classes.
After all, among these students, aside from those who only saw Baltigo Academy as a stepping stone into the Seireitei, intending to become superior to others, most of the students were still leaning towards the Revolutionary Army in their hearts.
The improvement of their strength was also equivalent to the increase in the Revolutionary Army's power.
As for the others...
Well, at least, before the Thousand-Year Blood War, Kyoya did not plan to turn against the Gotei 13.
These people joining the Gotei 13 could also become an indispensable backbone force during the Thousand-Year Blood War.
...
Time flew by, and several more decades passed in the blink of an eye.
Seireitei, 10th Division.
"Captain Shiba, these are today's division affairs..."
Rangiku pushed open the Captain's office door, carrying a thick stack of documents, and placed them on the desk.
"Huh? Why are there still so many?"
Seeing this pile of documents, Isshin's face immediately turned pale.
"Heh, who told you to go out and play so much recently, Captain? The leftover division's affairs naturally piled up."
"Rangiku, as the Lieutenant, don't you feel guilty making your Captain work so hard?"
Isshin looked at Rangiku with a pained expression: "I've always considered you as a Captain Candidate, and I've said long ago that if I'm not around, all affairs of the 10th Division are to be handled by you, Rangiku."
"How can you be so cruel as to make me handle so many squad affairs alone?"
"Ha, Captain Shiba, you've been saying that in my ear for decades now. How much trust do you think I still have in you?"
Hearing Isshin's words, Rangiku snorted coldly.
In the past, Rangiku, in order to be of help to Isshin, did believe his smooth talk and helped him handle division's affairs for a period of time.
But later, Rangiku also realized that while Isshin might have been somewhat sincere when he said that, more than anything, he just wanted to be lazy and dump all the division's affairs on her.
So, after a period of effort that didn't help much regarding Gin or Kyoya, Rangiku also gave up and slacked off.
If Isshin dared to sneak off to play, she dared to leave the non-urgent documents untouched and hand them all to him when he returned, letting him taste the flavor of overtime work.
"Rangiku, I really do want to train you as a Captain Candidate..."
Isshin cried injustice.
The reason Shiba came to the Seireitei and became the Captain of the 10th Division was, in a way, a probe from the Shiba Clan to see if the current nobles of the Seireitei would allow a member of the Shiba Clan to return to the Seireitei.
Or, to see if Captain-Commander Yamamoto of the Gotei 13 could protect a member of the Shiba Clan under the threat of the nobles.
There was no other way.
For the nobles of the Seireitei, what the Shiba Clan's ancestors did undermined the 'legitimacy' of their rule over the Soul Society.
Under such circumstances, how could they possibly tolerate the Shiba Clan?
For hundreds of thousands of years, the Shiba Clan had been subjected to the siege and pursuit of the Seireitei's nobles, brutally reducing the once-great one of the five great noble families of the Seireitei to just a few remaining members.
Out of necessity, the Shiba Clan split into the main family and branch families, using the lives of the branch family members to protect the main family.
Even so, the Shiba Clan suffered heavy casualties and was nearly wiped out.
Fortunately, a thousand years ago, after the invasion of the Quincy from the Lichtreich, Yamamoto forcefully entered the Seireitei, established the first line of defense for the Soul King Palace, and formed the Gotei 13.
After repelling the invasion of the Lichtreich, Yamamoto, with the power of the Gotei 13, seized the 'military power' from the nobles, renamed his Genji School to Shin'o Academy, and made it the academy for training orthodox Shinigami.
Thanks to the establishment of the Gotei 13, the Shiba Clan got a chance to catch its breath over the past few hundred years.
As the strongest remaining member of the Shiba Clan, Isshin rightfully entered the Seireitei.
Over the many years, Isshin also came to understand that as long as Yamamoto was still around, no matter how much killing intent the nobles harbored towards him, they could only hide it.
As long as he didn't make any fundamental mistakes, Yamamoto was the Shiba Clan's greatest backing.
A few years earlier, after receiving Isshin's assurance, the head of the Shiba Clan's main family also entered the Shino Academy.
Originally, Shiba Kaien was also supposed to join the 10th Division and eventually take over Isshin's position as Captain of the 10th Division.
However, 13th Division's Captain, Ukitake, worried that his health condition wouldn't allow him to properly perform his duties as Captain, went directly to the Shin'o Academy to invite Kaien to join the 13th Division after learning of his talent, and promised him the position of Lieutenant.
At that time, the Lieutenant of the 10th Division was already Rangiku.
In terms of strength at that time, Kaien was still considerably weaker than Rangiku.
Even if Kaien joined the 10th Division, he would, at most, have to settle for the third seat.
Under such circumstances, Kaien directly accepted Ukitake's invitation and became the Lieutenant of the 13th Division.
As for the remaining members of the Shiba Clan, both main and branch families, having experienced hundreds of thousands of years of pursuit, they would not stake the lives of their entire clan on others.
So, for now, only Isshin and Kaien were in the Seireitei.
This was also one of the reasons why Isshin strongly supported Rangiku as the 10th Division's Captain Candidate.
On the other hand, Isshin knew about the relationship between Kyoya and Rangiku.
He also knew that over the years, Kyoya's Baltigo and the Revolutionary Army had grown in the Rukongai to a point where they were almost comparable to the Seireitei and the Gotei 13.
Most of the currently surviving members of the Shiba Clan were still living in the Rukongai.
In fact, Isshin even knew that Kaien's sister from the main family had hidden her surname and joined the Revolutionary Army, and was currently a Division Commander in the Revolutionary Army.
Shaking his head, just as Isshin was about to start dealing with the division's affairs, his expression suddenly changed.
"Rangiku, I sense a Hollow's Reiatsu."
"I'll go check it out first. You handle these division's affairs for now!"
After saying that, Isshin directly opened the window of the Captain's office, jumped out, and flew towards the location where he sensed the Hollow's Reiatsu!
"Hey, Captain Shiba-"
Seeing Isshin do this, Rangiku immediately shouted: "Don't think you can dump this stuff on me!"
Immediately, Rangiku didn't bother with the pile of documents on the Captain's desk, her figure flickering as she ran after Isshin.
Neither Isshin nor Rangiku were worried that their actions would cause any serious consequences regarding these division's affairs.
After all, both of them were just lazy, not stupid.
The important documents and matters were inevitably dealt with immediately.
The remaining documents were merely written reports submitted by the 10th Division's members regarding some incidents they handled during patrols.
These things, even if piled up for a month or two, wouldn't matter.
After all, their existence was only to let the Captains have a general understanding of the affairs handled by their division's members, and to judge which members were good at handling which matters based on these reports, so they could make adjustments when needed.
However, having looked at this stuff for decades, both Rangiku and Isshin had a concrete understanding of everyone in the division.
Even without looking at these, they could roughly guess how any given Shinigami would react to certain incidents.
As long as it didn't involve nobles, basically nothing would happen.
The only ones that needed attention were the newcomers who had joined the division in recent years.
"This Reiatsu, it's so strong!"
Not long after following Isshin, Rangiku also sensed a strange, powerful Reiatsu.
