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

The spiritual pressure emanating from Unlimited Blade Works was also telling Erin that this was a weapon no less powerful than a Captain-level Zanpakuto.

After exiting the Reality Barrier, Erin drew his Zanpakuto from his waist. With a thought, the Zanpakuto in his hand instantly transformed into a katana.

Then, Erin swung the katana at his own hand.

"Shh!"

Like a phantom, the katana pierced through Erin's arm.

However, in Erin's perception, an unusual spiritual particle appeared in his arm. This spiritual particle seemed to carry his memories and was under his control.

Soon, through these spiritual particles, Erin also sensed spiritual particles within his own body that shared the same origin as his power.

Those spiritual particles seem to be invading my own spiritual particles, trying to write some information into my soul.

With a thought, the spiritual particles controlled by Erin instantly merged with Erin himself.

The next instant, the world spun around...

……

Zhenyang Spiritual Arts Academy, first-year class C.

Ten-year-old Erin was looking around with great interest at this place that only existed in her memories of her past life.

From today onward, I will study here and become a powerful Grim Reaper.

I just wonder when my cheat code will arrive, since I'm a time traveler?

Is it about absorbing the first wisp of spiritual energy yourself, or refining the first wisp of spiritual power?

Or perhaps you need to obtain a Zanpakuto yourself before you can activate it?

However, as long as it's not the kind of thing where "I've already become the captain, and then the cheat code comes along," that's fine.

Looking around at her classmates, Erin didn't find any familiar faces among them.

But Erin understood after thinking about it. The time when he transmigrated to the Shinigami was more than two hundred years before the start of the story. The people he knew had either already joined the Gotei 13 or hadn't even been born yet. How could they possibly be here?

However, when Erin saw a boy with medium-length black curly hair sitting in the front row, his pupils suddenly contracted.

That person—

Although he was much younger than she remembered, having gone from an adult to a minor, his appearance and the book in his hand unmistakably announced to Erin that the person's name—

Hidekuro Tsukishima!

"How is this possible? Tsukishima Hidekuro actually appeared in Soul Society at this time, and he's even in my class?"

She covered her face with her hands, trying to calm herself down so no one would notice the change in her expression.

"Something's wrong, so wrong."

"If my memory serves me right, Tsukishima Hidekuro was adopted by the first substitute Shinigami, Ginjo Kugo, and later formed the Xcution organization with Ginjo Kugo..."

"At this time, even the substitute Shinigami, Ginjou Kugo, might not have been born yet. How could Tsukishima Shukuro possibly be in Soul Society?"

With a thousand thoughts racing through his mind, Erin finally had a flash of inspiration when he thought of Tsukishima Hidekuro's abilities.

"By the way, Tsukishima Hidekuro's ability is to insert his own existence into the enemy's past, change the enemy's attitude towards him, and treat him as a 'friend' for whom he would give his life."

"Could it be that my future self is currently fighting with Hidekuro Tsukishima? And has already been slashed by him?"

At this moment, Erin, whose face was covered, didn't know whether to be happy or frustrated.

What makes him happy is that he will become a Shinigami in the future and live until the end of the Aizen arc.

Frustratingly, it seems my own strength isn't very high.

Erin remembered that Tsukishima Hidekuro's strength would be around captain level in the future. If he could fight Tsukishima Hidekuro, then he would most likely be the captain of one of the Gotei 13 divisions.

However, this guy slashed me, thus intruding on my existence, which means that my strength is probably similar to that of Tsukishima Hidekuro.

Perhaps in peacetime, such strength would allow one to live quite well.

However, just a few years after the Aizen arc came the "Thousand-Year Blood War".

Can I survive the attacks of those Quincy?

That day, Erin was in a daze and didn't even pay attention to what the teacher was saying.

That night, Erin lay in her dormitory, worrying about her future.

However, Erin suddenly rolled off the bed.

"No, that's not right, I still have a chance to change my destiny!"

Erin remembered that after Tsukishima Hidekuro became involved in other people's lives, he would also train with them, learn the enemy's weaknesses, and bring out the strength he had gained during the time he spent in his memories.

What if I start practicing diligently right now?

If my liver doesn't die, I'll train like crazy. In this way, when my memories return to the time when I fought Tsukishima Hidekuro, will my strength also become stronger?

Thinking of this, Erin took a deep breath.

"Give it a try. Anyway, things can't get any worse than this, can they?"

"Although I don't know what my 'current' strength is, in the battle of the Grim Reaper, besides various powerful abilities, the art of slashing is of paramount importance."

"If I could become a captain without Tsukishima Hidekuro's interference, I must be familiar with Shunpo, Hakuda, Kido, and Slash Techniques."

"The involvement of Hidekuro Tsukishima will only give him more time to spend with me. So, even if I don't have any contact with Hidekuro Tsukishima, I will make sure he is within my sight."

"Then, I will devote all my time to practicing swordsmanship!"

With the plan in mind, Erin abandoned other subjects and focused solely on slashing techniques during his time at the True Central Spiritual Arts Academy.

In Erin's mind, as the captain, he might lack a powerful move that could kill with a single blow. Therefore, in the past hundred years, he must master the strongest ultimate move.

Erin had originally thought he would have to specifically look for Tsukishima Hidekuro, but after Erin started cultivating, he suddenly realized that he didn't need to specifically look for him; as long as he started cultivating, Tsukishima Hidekuro would appear in his peripheral vision.

Now, Erin was completely relieved.

"My future self, when you recall this period of your life, please don't forget my sacrifices..."

In the blink of an eye, four years have passed.

Erin went from being a first-year student to a fourth-year student.

Naturally, because of Erin's unconventional ways, he also became an oddball at the True Central Spiritual Arts Academy.

He doesn't cultivate the demonic path, doesn't practice free fighting, and doesn't learn the Instant Step. Even when it comes to slashing techniques, he only cultivates slashing techniques.

At first, Erin would follow his teacher to practice basic swordsmanship. Later, Erin gradually abandoned everything else and only practiced one strike—the slash.

With each swing of the sword, he unleashes all his strength, even beyond his own.

This resulted in Erin consistently achieving the worst score in each year's promotion assessment.

The scores for the other three subjects were all zero.

Only his slashing technique was somewhat better. After three years of training in slashing, Erin had actually developed some skills. In the entire fourth-year Class C, there were no more than three people who could withstand a single strike from Erin.

Because Erin knew Tsukishima Hidekuro's purpose, he focused solely on training for the past four years and never spoke to him.

On several occasions, when Erin was training, Tsukishima Hidekuro would stand by and offer advice to correct Erin's training posture. Erin would try it, and if it worked, he would make the necessary adjustments and continue his training.

Its main selling point is getting things for free.

On this day, Erin continued practicing his sword-drawing technique when he suddenly shuddered, and his gaze instantly became incredibly sharp.

"Is this where I was still studying at the True Spiritual Arts Academy?"

"I succeeded!"

A slight smile appeared on Erin's lips, but he quickly composed himself, closed his eyes, and began to examine his memories.

Because his movements were a little slower than Tsukishima Hidekuro's, Erin realized from his memories that Tsukishima Hidekuro appeared in the year he entered the Shinigami Academy.

Although he was only less than fifteen minutes slower than Tsukishima Hidekuro in reality, Tsukishima Hidekuro's spiritual particles had already infiltrated the information to the extent that Erin had been a fourth-year student at the Shinigami Academy.

However, Erin, who had absorbed "her own" memories from the past four years, couldn't help but complain.

How much did my past self distrust my future self?

How could someone think that Hidekuro Tsukishima's abilities could threaten them?

In order to prepare a killing move for himself, he even planned to keep this "slashing technique" in front of Tsukishima Hidekuro and hone it into his ultimate killing move.

Stroking the knife at his waist, Erin's lips curled into a slight smile.

"Alright, since this is 'my' wish, then I will fulfill it for 'my' sake."

"For over a hundred years, I've only honed this one sword technique!"

With Erin's current swordsmanship skills, the sword strike that the previous "Erin" had practiced for the past four years was only about the same.

But this is a treasure left by my "past" self to my "present" self...

"Don't worry, I will hone this strike to its full potential and make it one of my strongest finishing moves in the future."

With the activation of Unlimited Blade Works, Erin instantly absorbed all of his training experience from the sword, accumulated day after day and year after year.

Chapter 161 An unexpected surprise

Then, Erin stopped using his abilities and instead honed his sword by following the path that "he" had previously planned.

To hone this strike into his own trump card is Erin's promise to his former "self".

Erin closed her eyes and relaxed her body.

Then, in a single instant, all the strength in his body became completely unified, rising from the ground beneath his feet, coordinating with his body, and converging in his right hand. Then, along the scabbard, he drew a white streak of light.

"Shh-"

Under a large tree by the playground, Tsukishima Hidekuro suddenly looked up, staring at Erin in shock.

Not far ahead of him, the boy had already sheathed his sword.

The wooden stake, broken in two, demonstrated the power of the man's strike.

"how is this possible?"

"Just a short while ago, he still needed my guidance in his cultivation. How come he has already succeeded in his cultivation now?"

Hidekuro Tsukishima quickly turned his gaze to the "Book of the End" in his hand, which contained the more than one hundred years of life of "Erin".
