Killing You All in the Dark!

As Gaoyu placed his hand on his face, he felt a surge of power from the depths of his soul.

This power was destroying his soul, causing another power, opposite in nature to his current one, to emerge.

A touch of white gradually appeared on his face, spreading rapidly until it formed a mask on Gaoyu's face.

In an instant, an extremely evil, black and red Reiatsu erupted from Gaoyu's body!

BOOM!

Gaoyu felt his Spiritual Power swell several times over at that moment, but this surging power didn't make him lose his mind. He felt no different than before.

When other Hollows underwent Hollowfication, they were truly fighting for their lives against the power of the Hollow, to prevent losing themselves. But Gaoyu was different. Gaoyu was using a Soul Ability. Unless the ability description mentioned some kind of side effect, it wouldn't harm him.

The duration of Hollowfication was related to the strength of one's soul. The stronger the soul, the longer it could be maintained.

With his current soul strength, he could maintain it for about five to six minutes. While not comparable to the elite members of the Visored, it was much better than Ichigo Kurosaki.

After the Hollowfication ended, the mask on Gaoyu's face disappeared.

However, the boundary between the souls of a Shinigami and a Hollow had been permanently broken by him.

From now on, as time passed, Gaoyu would eventually be able to Hollowfy at will.

But this Hollowfication wouldn't be like this Soul Ability. This Hollowfication would be similar to that of the Visored, with a risk of losing control.

Unless he could raise White Hollow's affinity to eighty, he could then use risk-free Hollowfication.

"Not bad."

Gaoyu smiled. He had only been in this world for a year since his transmigration, and he already possessed the ability to protect himself.

Even if the Quincy invaded in the future, he was confident he wouldn't be cannon fodder.

Seriously, if he couldn't defeat the Sternritter, couldn't he defeat the Quincy foot soldiers?

Was he, a Vice-Captain, supposed to fight the Sternritter?

Or was he supposed to fight the Royal Guard?

Or perhaps...

Really?

Was he supposed to fight Yhwach?

Thinking of this, Gaoyu smiled again before falling asleep.

The next day, on his way to the division, Gaoyu saw a familiar face and greeted her.

"Miss Nanao, good morning. Coming to the Fifth Division so early, is something the matter?"

Gaoyu raised his hand in greeting.

That's right, he saw the Vice-Captain of the Eighth Division, Nanao Ise.

Nanao seemed a little surprised as well. She said, "Vice-Captain Gaoyu, please check the time. The entry period has already passed. You're late."

"Huh?" Gaoyu scratched his head sheepishly. "Captain Aizen wouldn't care about such a small matter anyway."

"You're here, so there must be something, right?"

"I have some information to give to Captain Aizen, and I also need to go to the Fifth Division Library to borrow some books."

"Going to the Fifth Division Library." Gaoyu rubbed his chin and exclaimed, "As expected of Vice-Captain Ise. You can even read those obscure academic books in the Fifth Division Library."

Within the Gotei 13, each division had a medium-sized library within its jurisdiction.

The libraries were directly managed by their respective divisions, so they generally stocked books that the divisions were interested in.

For example, the Fourth Division stocked many medical books, and the Sixth Division stocked books on noble etiquette and clan rituals. Most of the books in the Fifth Division Library were placed there by Aizen.

Aizen had somehow procured a pile of serious academic books, making it so that not many people in the Fifth Division area actually read them. They wouldn't understand them even if they did.

"I'm an honorary member of the Shino Academy Library, don't underestimate me."

An honorary member of the Shino Academy Library was a title awarded to Shinigami who borrowed over a thousand books within a year. So, Nanao Ise was indeed a person who loved to read.

Because Gaoyu occasionally went drinking with Shunsui Kyoraku, he was quite familiar with Nanao Ise, although she didn't have a good impression of him.

This was because Nanao Ise hated Shunsui Kyoraku drinking, and Gaoyu insisted on taking Shunsui Kyoraku out for drinks, which touched a nerve.

Gaoyu understood this, but he couldn't help it; he had to raise Shunsui Kyoraku's affinity.

However, he also wanted to raise Nanao Ise's affinity. Her Soul Ability, 'Mirror Reflection,' was something Gaoyu had coveted for a long time.

So, after a moment's thought, he asked, "Vice-Captain Ise, what kind of books are you looking for?"

"Hmm?" Nanao blinked, seemingly surprised that Gaoyu would ask such a question. However, she replied, "I'm looking for books on Kidō techniques. The Eighth Division Library doesn't have relevant books, so I thought perhaps the knowledgeable Captain Aizen might have some."

"I see. Then I recommend these three books: The Blank Soul, The Birth of Kidō, and On Abandoning Incantations. They are all in Section B on the second floor of the Fifth Division Library. Vice-Captain Ise should be able to find them easily." Gaoyu smiled faintly.

"!"

Nanao Ise was stunned. She hadn't expected Gaoyu to say something like that.

In her impression, Gaoyu was just a lucky guy who killed a strange Menos Grande and became a Vice-Captain.

Moreover, this lucky guy would go drinking with Captain Kyoraku, and he was reportedly undisciplined in the division, not working seriously every day.

For someone like her who took her responsibilities seriously, she didn't have a good impression of Gaoyu.

But now, Gaoyu was showing a completely different side of himself compared to the rumors.

"Th... Thank you."

After a moment of stunned silence, Nanao Ise quickly expressed her gratitude to Gaoyu. She said, "I'll go take a look."

"I'm glad I could help Vice-Captain Ise. Alright, I need to get back to the squad too. If I'm any later, Captain Aizen will have something to say."

Gaoyu greeted her with a smile and then hurried back to his squad.

He was a top student!

Don't think you can stop studying just because you've transmigrated. How could you not study? Don't you know that science and technology are the primary productive forces?

Don't you know that scientists are given preferential treatment in this world?

Look at Kisuke Urahara and Mayuri Kurotsuchi, those two. Just because they're scientists, haven't they always been incredibly powerful and full of trump cards in every fight?

Gaoyu was very envious.

Studying can change your destiny!

The books Aizen had acquired in the Fifth Division's library were incomprehensible to others, including Gaoyu at first.

But that didn't matter. If you don't understand, just read more!

If you read enough, you'll naturally understand!

Did you really think he was slacking off in the squad every day?

Wrong!

I'm going to secretly outwork all of you!

I'm the king of grinding!
