Only I know the plot of the anime.

The day before the assessment.

Su Jin sat cross-legged in the training room, his Zanpakuto lying horizontally on his lap.

After entering the True Central Academy of Spiritual Arts.

The academy will assign each student a [shallow strike].

Then everyone would carry it with them at all times, whether eating, attending class, or going to bed, maintaining this practice regardless of the weather.

By continuously infusing their essence, Shinigami can transform Asauchi into their own Zanpakuto!

Su Jin had already succeeded.

The Grim Reaper's next training goal is the first stage of sword liberation.

Its name is 【Shikai】!

After activating Shikai, not only will the appearance of the Zanpakuto change, but it will also gain various unique abilities.

For example, Rukia's Sode no Shirayuki can release cold air and freeze enemies.

Although the actual principle.

It freezes objects by continuously lowering the temperature of the holder's flesh.

Or perhaps it's Renji Abarai's Hebimaru, which can transform into a snake-belly shaped blade that can extend and retract freely.

And then there's Ikkaku Madarame's Hozukimaru, whose Shikai transforms his longsword into a flexible three-section staff and spear—well, let's not even go there, it just makes it easier to break.

It is far inferior to Kuchiki Byakuya's "Senbonzakura".

After its initial release, the blade can break down into thousands of blades, invisible to the naked eye, and when activated, it resembles a shower of cherry blossoms.

However, even among the Shinigami of the Gotei 13, most still wield swords and slash with Natsume Tomoe.

Only a minority will be able to understand it.

As for mastering the [Shikai] during one's time at the Spirit Arts Academy, that's something only geniuses can do.

......

Just then, a female voice, devoid of any emotion, suddenly rang out.

"Your initial release is a similar version of the Decade card."

"By making friends and gaining their approval, you can make your Zanpakuto transform into their Shikai. But you don't think that will allow you to sweep away all enemies, do you?"

"The battle between Shinigami is a battle of spiritual pressure!"

"Your problem is that you're too young. At best, you're a Shinigami who's been training for less than a year. And a Shinigami's growth and the increase in spiritual pressure require a lot of time. So right now, you're in an even more awkward position than Toshiro Hitsugaya."

"Should I congratulate you, you genius, and celebrate that you've gotten the script for Yanqing and Dongshilang? You're probably going to suffer endless setbacks later."

Having potential and having strong ability are two different things.

"After all, even someone as powerful as the Heavenly Emperor had his bones dug out when he was a child."

Su Jin's lips twitched slightly.

He looked at the person who spoke, who resembled the character "Long Night Moon" from a certain six-character game. She was holding an umbrella and staring at Su Jin with her lifeless and indifferent eyes. Suddenly, she closed the umbrella and took out a camera instead.

I just took a picture.

The girl was deeply moved.

"World traveler, camera, oh right, my name is Long Night, I don't have a moon, after all, I am essentially the [spirit] of your Zanpakuto, born because of you. I have nothing to do with the one in the game."

"Tsukasa's sister is named Sayo, and I also have the character 'Yo' in my name. Perhaps this is a kind of fate."

"But perhaps, the long night also corresponds to your fate."

"Because your spiritual pressure is too low, the future is destined to be a long, dark night. Oh dear, I hope you can face it bravely."

After saying that.

She disappeared.

Su Jin's forehead creased with annoyance.

This guy's personality is definitely not like mine; there's a hint of schadenfreude in his tone. It's really disgusting.

Although what she said wasn't wrong, the growth period of the Grim Reaper is too long, often taking hundreds of years.

When the Bleach storyline officially began, Rukia was over a hundred years old.

Her performance speaks for itself.

Even according to Byakuya's statement, based on the timeline of Rukia's appearance, he found Rukia the year after Byakuya's wife, Hisana, passed away fifty years ago, even though Hisana couldn't be found before.

What a tragic couple!

So, from mastering Shikai to mastering Bankai and becoming a captain, Shiro spent a full 40 years training.

Unfortunately, he is the youngest captain in the history of Soul Society.

It broke previous records.

The most genius.

So what about myself?

From Su Jin's perspective as a human, several decades is already a very long time.

In this regard.

He didn't say anything, but continued his practice.

Through his senses, he discovered a space inside the Zanpakuto, Nagayo, where Su Jin's own human body was quietly floating. This was much better than Kurosaki Ichigo's situation, where he had to constantly rely on the [Modified Soul] to control his body.

Human death gods are just that troublesome.

The soul leaves, but the body remains in the same place.

Just like Kamen Rider W, when Philip transforms by combining with Shotaro Hidari, his body is often dragged away by Akiko Narumi.

Su Jin then sensed it.

This space, well, it's not very big. It's enough to fit a few pieces of clothing at most.

Something is better than nothing.

.....

the next day.

Su Jin looked at Rukia opposite him.

"I didn't expect it to be you."

"Looks like I'll have to hold back a bit; I can't let you lose too badly."

Rukia's eyes widened.

"You jerk, don't get too cocky!"

"You are clearly the challenger."

Instead, they adopted an attitude of complete confidence.

Who do you think you are!

"Bring it on, let me see your full strength. After all, I deserve some credit for your demonic arts level."

The students standing at a distance on both sides were clear about it.

Su Jin and Rukia were old acquaintances.

Rukia even lent him her notes on the Kido (Demon Path) technique.

at this time.

The former drew his Zanpakuto.

"Full strength?"

"Then watch closely as I demonstrate my efforts and awareness during this period."

Even if I lack experience, even if I am too young.

They still have their own methods.

"One-Sword Asura!"

As soon as he finished speaking, Su Jin's spiritual pressure suddenly surged, exceeding five times, ten times, and dozens of times his original state!

The surging power spread instantly.

Cover this entire area!

The faces of everyone present changed drastically. They were all immobilized by the pressure, and many were forced to lie on the ground, struggling to lift their heads in disbelief.

"What incredible spiritual pressure!"

"How could that be?"

Even the teacher looked shocked.

What kind of move is this?

Why can Su Jin's spiritual pressure change so drastically in the blink of an eye?

For Rukia, almost instantly, everything went black and she lost consciousness.

She was completely unaware that Su Jin was already standing behind her.

He then slowly sheathed his sword.

In this regard.

Su Jin helped Rukia to her feet and helped her fall to the ground safely.

His expression was calm.

He muttered to himself.

"This is my answer."

Su Jin already knew about the problem of being humiliated that the sword spirit had mentioned.

Although my personal information is the same as Rukia's.

They are refugees from Rukongai.

But in reality, as a Gaia, I am indeed young and have low spiritual pressure. With so little spiritual pressure, how can I fight?

So when Su Jin discovered that the Grim Reaper's body was actually not much different from the human body's structure...

He suddenly had an idea.

Life can suddenly unleash power far exceeding normal levels during a crisis. If this power is unleashed, even for just a short moment, it can still generate tremendous strength.

Just like that Ikki Kurogane.

I will use my weakest strength to defeat your strongest!

Therefore, Su Jin focused his energy on this aspect during this period, refining the [Return to the Dao] and the human body, exploring potential, and combining it with his knowledge from his previous life, thus creating this move.

Do you really think you're the same idiot who jumped into the river and committed suicide?

He's not that shameful.

And [One-Sword Asura].

As the name suggests.

Within one minute, I can fight with all my might. After that time, I will be in a period of severe weakness and will not be able to use this move again for the rest of the day.

This is an alternative way to compensate for the low spiritual pressure.

It keeps popping up like a crescent moon in the sky.

So, it's not too much to just unleash a devastating attack myself, is it?
