Crossover Anime: Starting with Bankai from Demon Slayer

Chapter 410 A New Mission, A New World

A deep blue light flickered in the empty hall.

Nichika sat cross-legged in the center of the main hall, her face pale and her forehead covered with fine beads of sweat.

Within her spiritual energy network, complex patterns, resembling circuit diagrams, pulsed and constantly emitted strange fluctuations.

With each breath, these patterns shimmer in sync with the heartbeat.

"How are you feeling, Hinata?"

Aizen Sosuke sat not far away, his hands elegantly folded in front of him.

Rika didn't answer directly; she tried to concentrate and muttered something under her breath.

A small cloud of water mist condensed in the air, slowly rotating and transforming into a water ball the size of a thumb, which floated in her palm.

But it only lasted a few seconds before the water sphere shook and broke apart, splashing up a few drops of water.

...It's amazing, like a completely new channel has been opened up in the cracks of my soul...I can feel an energy that is different from spiritual power, yet very similar..."

'

"...This is a magic loop?" Nika frowned, looking at her palm with some discouragement. "It's too weak, and it consumes a lot of spiritual energy. It feels like I should just use Kido directly..."

'

"You're right."

Aizen stood up and strolled over to her: "From a purely practical standpoint, these inferior magical circuits on you are indeed utterly useless."

"Even if you exhaust all your energy, the magic you can perform is like child's play in front of the Death God of the Kido Class."

However, he did not show any disappointment; on the contrary, the smile on his lips deepened.

"But you must understand that the true value of this is not in how much power you gain, but in the fact that it exists."

Aizen's voice was deep and magnetic, carrying an irresistible persuasive power: "The laws governing the operation of the Soul Society, the Human World, and Hueco Mundo have long been fixed by the existence of the Soul King."

"All power is a system derived from the fundamental concept of spirit particles."

"But now, a new answer has emerged."

He placed his hand on Rixiang's shoulder, which made the girl's pretty face turn red instantly.

"The Hogyoku can materialize the wishes of those around it, but only if those wishes fall within the framework of laws the Hogyoku can comprehend, and if the person making the wish possesses the ability to materialize them..."

"Since the Hogyoku was able to successfully create a magic circuit within your body, no matter how inferior it may be, it undeniably proves one fact: 7"

"The laws of power in different worlds are compatible in this world as well."

"It is even possible to achieve dimensionality reduction or isomorphic reproduction through this method, which we have not yet fully analyzed."

This is what truly excites Aizen.

This poorly constructed magic loop is like a tiny crack that pries open the door to a new world.

Although only a sliver of light can penetrate now, as long as that sliver is there, he can completely destroy the entire door.

"Go and rest, Nika." He whispered in Nika's ear.

"Your body needs time to adapt to these external forces. Next, I will have others conduct more in-depth field investigations."

After Nichika left with a flushed face, Aizen walked out of the laboratory and came to the spacious reception room of Las Noches.

Not long after, accompanied by two distinct spiritual pressure fluctuations, the door to the reception room was pushed open.

Leading the way was Soujiro Mochi, who, despite having defected from the Spirit Court, still wore impeccable noble attire and had a cold, stern expression.

His eyes remained calm and still, and even his footsteps were barely audible, as if he had become one with the surrounding air.

Zhicheng naturally found a chair and sat down. He neither bowed nor spoke, but simply waited quietly for what was to come.

He was not Aizen's subordinate; the relationship between the two was more of an alliance based on mutual exploitation and a shared set of ideals.

Behind Mole City stood a tall, upright young man with scarlet eyes and sapphire-blue hair.

Machiri Zorgne after her face was broken.

Having experienced the cycle of life and death, he is now one of Aizen's personal guards in Hueco Mundo, the Zero symbolizing [obsession].

"Lord Aizen."

He was much more respectful to Aizen than to Soya Azajo.

"Sit down, Machiri." Aizen smiled and gestured to the chair in front of him.

After Machiri was seated, Aizen got straight to the point.

"Gentlemen, I need you to go on a long journey."

Have you ever heard of the city of London?

Mole City shook his head; he actually rarely even went to the real world.

"Ah, what a nostalgic name," Machiri chimed in. "It's been a century since I've been back there. I wonder how much it's changed..."

'

Aizen nodded: "I only learned about this city called London in the West many years ago through some channels."

"There exists a small world separate from Soul Society, known as the West Frontier Bureau's alternate dimension."

"I've heard that the laws there are very different from ours, and that they use a power called magic."

"Now that Nika's magic loop is basically complete, it needs some corresponding power to cooperate..."

'

He looked at Machiri and smiled, "Machiri, I need you to confirm whether this power is the same type of magic you are familiar with."

"In addition, if possible, it would be best to bring back some substantial samples."

"Whether it's the corpse of one or two magicians, a spellbook that records the logic of power, or their [dragons], it's all acceptable."

Upon hearing this, the atmosphere in the reception room momentarily froze.

This is a reconnaissance and plunder mission that delves into unknown territory and is fraught with risks.

Machiri lowered his head almost without hesitation: "I obey."

Even if this wasn't Aizen's order, purely out of curiosity, he really wanted to see what the difference was between the West Coast Bureau that Aizen spoke of and the London he knew.

Aizen nodded, then looked at the silent Sōya Azashiro.

"And what about you, Shuang too?"

"Your Dew-laden Pomegranate has the ability to merge with all matter and spiritual particles, making it the best choice for carrying out covert reconnaissance missions... Only with you traveling with Machiri can I be absolutely certain that everything will go smoothly."

Mochijo looked directly at Aizen, remained silent for a moment, and then spoke: "I can go."

"Observing a completely new system of laws might also help improve my Bankai. But Aizen, I must say this upfront."

His voice was completely emotionless: "I know nothing about the danger level of that world, and I don't know if there are any beings there that could threaten me."

"If we encounter any unknown danger, I will not go all out for your experimental data, let alone risk my life."

"My top priority will be self-preservation, do you agree?"

If these words were spoken by the Espada, it would undoubtedly be tantamount to treason.

But in Mochi Castle, Aizen showed an understanding smile.

"This is natural, it is a pair."

"I sent you there only to gather intelligence. If there's any risk, you can of course choose to avoid it."

Aizen's tolerance was not a pretense, but stemmed from his absolute confidence and rationality.

He knew Sōya Mochijō's personality very well; he was an extremely rational and pragmatic man.

Getting him to agree to go to an unknown and mysterious realm was already Aizen's goal.

"Since neither of you has any objections, let's talk about how to travel."

Aizen opened the drawer and took out a small envelope.

"Because that world is self-contained and not connected to the dimensions of Soul Society and Hueco Mundo, I cannot open the Black Hole to send you there."

With that, Aizen handed the envelope in his hand to Sōya Azashiro.

Upon opening it, there were no complicated runes or information scrolls inside, but rather two beautifully printed pieces of cardboard.

Several lines of text were clearly printed on it in English and Japanese.

Those were two international flight tickets from Japan to London Heathrow Airport in the UK.

Moreover, it was first class.

Aizen rested his hands on the table, smiling as he watched the two people with their different expressions.

"Wishing you both a safe journey."
