I'm in Bleach, starting with Unlimited Blade Works.

But this time, he didn't sense Erin's presence until Erin was right next to him.

With just the skill of "concealment," Erin is no less capable than himself.

Has Erin made such great progress in such a short time?

Although he had doubts, Furuta Aoki didn't say anything.

They are a pack of hyenas in the shadows, specializing in dealing with the shady dealings of Soul Society. As long as it doesn't involve themselves, who cares about anything else?

As one of the squads with the highest casualty rate among the Gotei 13, their task is to survive each mission.

"Whoosh..."

"Whizzing……"

A series of black figures moved swiftly up and down in the barracks of the Second Division. Soon, before the emergency assembly order had even stopped, the five large divisions and fifty small squads of the Execution Army, totaling two hundred and fifty people, had all assembled neatly in the vast training ground.

"call out!"

With a whooshing sound, two figures suddenly appeared at the very front of the Second Division's training ground.

The two figures were: one was Yoruichi Shihouin, the captain of the Second Division, who wore a yellow and black vest, black leather pants, and had medium-length purple hair.

The other one had slightly messy, pale yellow hair and hazy eyes, and seemed uninterested in anything.

This is Kisuke Urahara, the current vice-captain of the Second Division and also the captain of the supervisory team overseeing the Worm's Nest.

Even with Erin's current abilities, he only heard the sound of wind breaking after the two of them appeared.

"Everyone, recently many souls have disappeared without a trace in Rukongai. The Captain-Commander has ordered us to find out the reason for the disappearance of the souls as soon as possible."

"The First Brigade is responsible for investigating the eastern district of Rukongai."

"The second squadron is responsible for reconnaissance of the western district."

"The Third Brigade is responsible for the southern area."

"The Fourth Brigade is responsible for the North District."

"Fifth Squadron, come with me to investigate Seireitei."

"Yes!"

After receiving their respective tasks, everyone quickly transformed into streaks of light, using Instant Step to rush to their assigned areas to investigate.

Erin's squad belongs to the Fourth Battalion, and their reconnaissance area is the northern district of Rukongai.

The Rukongai has four districts, each divided into eighty-one wards, with the order becoming increasingly chaotic as you move down the list.

Perhaps due to Erin's increased strength, this time Furuta Aoki assigned Erin the exploration area of ​​the 61st and 62nd wards of Rukongai.

Compared to the area in front of Seireitei, the residents' homes in the blocks behind number 60 have become extremely dilapidated.

Furthermore, there are no fixed trading venues here, and fights break out frequently.

"Whoosh!"

Erin's figure appeared in the shadows of a corner of a room. With his aura completely concealed, no one in the room noticed that there was another person around them.

Having noted down the spiritual pressure of these people, Erin continued to travel between North 61st and North 62nd Districts, recording their spiritual pressure.

These ragged, skeletal wandering souls were clearly not the culprits responsible for causing souls to disappear without a trace.

But they are the souls most suitable for "disappearance" in the eyes of the culprits.

After Erin recorded their spiritual pressure, he was able to sense it within a certain range and use it to judge their condition.

The most profound memory Erin has of his soul disappearing without a trace is the incident of Aizen Sousuke developing the "Hogyoku".

However, it is clear that the timing is wrong.

Or perhaps it's because this is the real world, and Aizen Sousuke researched the Hogyoku even earlier than he knew?

Erin focused his mind, maximizing his sensory abilities, sensing the spiritual pressure around him while pondering the root cause of this incident.

Having spent the last thirty years in Soul Society, Erin has roughly figured out where he is in the current timeline.

This is about two hundred years before the Bleach storyline begins.

The captain of the 2nd Division is Yoruichi Shihouin; the captain of the 3rd Division is Rojuro Ootorihashi; the captain of the 5th Division is Shinji Hirako; the captain of the 7th Division is Rabu Aikawa; the captain of the 9th Division is Kensei Muguruma; the captain of the 10th Division is Isshin Shiba; the captain of the 11th Division is Kenpachi Azajo; and Kiryu Hikifune is still the captain of the 12th Division.

Suddenly, a thought flashed through Erin's mind—

Before Aizen, Kisuke Urahara had already successfully created an incomplete "Hogyoku".

Could it be that this incident of soul dissipation was orchestrated by Kisuke Urahara?

Why did Captain Yoruichi send the Second Division to investigate Rukongai in such a high-profile manner, while he and Kisuke Urahara investigated Seireitei? Was he doing this to clean up after Kisuke Urahara?

Think about it carefully, why were those nobles in the Central 46 so certain that the Hollowfication experiment was done by Kisuke Urahara more than a hundred years later?

The only possibility is that Kisuke Urahara has a criminal record!

Thinking of this, Erin paused for a moment.

"Forget it, these things are beyond my knowledge and ability to handle. I'll just focus on doing my job well."

Without further thought, Erin continued recording the spiritual pressure of the wandering spirits in the two areas under his jurisdiction, and continued to move around these two areas haphazardly.

If Erin senses the disappearance of spiritual pressure, he will definitely send out a signal and escape immediately.

I've just acquired what I consider to be the "strongest" ability, how can I be willing to die here?

Fortunately, this situation continued until the end of the mission, and nothing unusual happened in the area that Erin was in charge of.

After that, the Second Division returned to peace, and Erin resumed his routine of copying other people's Zanpakuto during the day at the training grounds, and then forging the Zanpakuto he had copied during the day in his own mental space after returning to his dormitory at night.

Furthermore, by absorbing the combat experience of these Zanpakuto wielders, one's own strength gradually increases...

Chapter 3 The Tapir Knife Incident

"call!"

"Hoohoo!"

"call!"

On the training ground of the Second Division, Erin held his Zanpakuto and practiced intently.

If someone were to carefully observe all the people training on this training ground, they would find that Erin's training at this moment is very similar to that of one of these people.

This is because the Zanpakuto in Erin's hand at this moment is not his own Zanpakuto, but a projection from his own mental space.

By grasping this Zanpakuto, Erin gained all the experience of its master.

However, these experiences only appear in Erin's mind when he grasps the projected Zanpakuto.

Erin was confident that he could hold his own against those whose Zanpakuto he had copied in a short period of time.

After all, their opponent is not someone else, but themselves.

However, Erin was not content with being evenly matched with others, but instead worked even harder to cultivate, turning the experience of these people into resources for his own further advancement.

Hira-tai, slashing techniques, Shunpo (flash step), Kido (demon arts)...

Each member of the Executioner has their own signature moves or practical tips that they have mastered over decades or even centuries in the four Death Techniques.

One person's weakness may be another person's greatest strength.

Every so often during training, Erin would sheath his Zanpakuto and secretly activate his Shikai, projecting his Zanpakuto onto the Zanpakuto of other people to practice and master their special techniques.

Once Erin absorbs all of their experience, just how strong will he become?

No one knows!

Even Erin herself is currently somewhat unsure of her own position.

However, Erin was certain that Captain Furuta, whom he had previously considered very strong, was no longer a threat to him whatsoever.

Furuta Aoki was also among the top-ranked squad leaders in the Criminal Investigation Department.

According to a drunken remark he made on one occasion, Furuta Aoki said he almost became the last member of the Second Division.

In each squad, in addition to the captain and vice-captain, there are seventeen seat officers who assist in managing the squad, ranging from the third seat to the twentieth seat.

The last seat, which is the twentieth seat.

These officials were generally appointed based on their relative strength.

After all, if someone is not strong enough and is defeated in front of everyone, the winner will take over the seat of that official.

Although the Second Division has four sub-districts, the strongest of them is the Execution Army.

It's not that other squads don't have strong members, but the strong members in other squads are probably only a few squad leaders and a few squad sub-squad leaders.

Erin guessed that even if Furuta Aoki was exaggerating, his strength in the Second Division was at least in the top fifty.

Having surpassed even Furuta Aoki in strength, he might have truly gotten close to the position of the Seat Official.

"Bang bang bang, bang bang bang..."

Just as Erin and the others were practicing with great enthusiasm, the emergency assembly order for the Second Division came to mind again.

However, not everyone gathered at the training ground this time.

Because hundreds of messenger butterflies had already flown over the Second Division and stopped nearby.

Erin extended his left hand, and a hell butterfly landed on his index finger.

Upon somehow obtaining information from the Hell Butterfly, Erin dared not delay and rushed to the noble residence in Seireitei.

According to the information from Hell Butterfly, it seems that the upper-class noble family of Kasumioji has been attacked and urgently needs the Grim Reaper to come to their rescue.

"The Xia Dalu family?"

Following the guidance of the Hell Butterfly, Erin hurried towards the Kasumi family home, while recalling in his mind whether his recent mission corresponded to certain events in his memory.

"If I remember correctly, the Kasumi clan is the one that created the Baku Blade, but ultimately lost to Nimaiya Oetsu and failed to advance to the Spirit King Palace, right?"

"and……"

"The Baku-yōtō is a weapon that can directly grant the user immense power simply by providing spiritual pressure. Even someone who has completed the Shikai of a Zanpakutō may not necessarily be able to defeat someone who uses the Baku-yōtō."

Although the Baku swords do not have a Shikai or Bankai like Zanpakuto, each Baku sword possesses unique abilities, and anyone can use them as long as they provide spiritual pressure.

It can be said that the Mo Yao Blade is as solid as iron, while the Grim Reaper comes and goes like flowing water.
