Chapter 186: Mayuri's Proposal
Over the next two days, Satoru was unusually well-behaved.
Aside from his daily training, he just lazed around and teased Suì-Fēng.
He didn't cause any trouble, not even leaving the Seireitei.
Seeing his disciple acting so out of character, Yamamoto was initially quite alarmed.
But as time passed, he grew accustomed to it.
And so, the Soul Funeral Ceremony concluded without any major incidents.
On the surface, it appeared to be just a normal memorial service.
Only a select few knew that behind this funeral, three Captains' souls had been permanently sent to hell.
During the ceremony, Aizen's expression was one of profound grief.
Seeing him like this, Shinji couldn't help but be puzzled.
He had always thought his Vice-Captain was the cold, unfeeling type who didn't care about anyone except Satoru.
But the sorrow he displayed now didn't seem feigned.
Was this... the complexity of human nature?
Shinji scratched his head, lost in thought.
Meanwhile, Aizen silently gazed at the sky.
Farewell, my three premium research subjects.
After you go to hell, live well and strive to be researched by me again someday as denizens of hell...
On the night the ceremony ended, Aizen rushed to the Second Division, grabbed Satoru, and left immediately.
Donning cloaks, they secretly left the Seireitei under cover of darkness, arriving at a remote location.
Aizen created a barrier to prevent their Reiatsu from leaking.
Then, he opened a portal to Hueco Mundo.
Back when he first traveled to Hueco Mundo with Satoru, he had been somewhat nervous.
Now it felt like going shopping on the next street over—not a ripple of emotion in his heart.
Skillfully crossing through the spatial layers, they returned to the endless landscape of Hueco Mundo.
After confirming there were no Hollows nearby, they nodded to each other and headed for their previously marked location.
After nearly two hours of running through the desert, they finally reached their destination.
At the foot of a small hill, they dug out a stasis pod.
Inside the large glass container, Kōga Kuchiki floated silently.
The nutrient solution in the glass container had become quite murky by now.
The indicator needle for anesthetic concentration had already entered the danger zone.
After double-checking everything, Aizen breathed a sigh of relief.
"Good, we made it in time."
"All parameters are still within controllable ranges... If we had arrived one day later, it would have been uncertain."
As he spoke, he took out various prepared medications and began changing Kōga Kuchiki's solution.
Satoru stood by, keeping watch for Aizen.
Originally, they had planned to transfer Kōga after establishing the Hueco Mundo branch of the Technical Department.
However, the Soul Funeral Ceremony arrived too quickly. To prevent Kōga from being discovered, they had no choice but to hide him along with the containment tank.
After changing the water and adding the medication, Aizen gave a slight nod.
"Four days should be fine."
He sounded somewhat resigned as he said this.
Changing the water every four days wasn't particularly troublesome for him.
The real issue was that keeping Kōga here represented a massive waste of resources.
All sorts of experiments related to him had been forced to postpone.
Unless he could establish a laboratory in Hueco Mundo, this situation would persist indefinitely.
Moreover, his frequent trips back and forth would inevitably draw attention sooner or later.
If Kōga were discovered and taken by someone else, he would become a complete fool.
Establishing a laboratory in Hueco Mundo was urgently needed!
Aizen gazed at the endless silver dunes.
If his power were greater, there was one approach—
Directly establish a faction in Hueco Mundo, gather a group of Menos Grande, and rival Las Noches.
Unfortunately, the world wasn't filled with so many "ifs."
For now, he could only take things one step at a time.
Satoru stood nearby without saying a word.
After dealing with Kōga, the two hurried back to Soul Society.
Returning to the Second Division barracks, Satoru went straight to the Technical Department without hesitation and found Kisuke Urahara and Mayuri Kurotsuchi.
"How's progress on the secret base I requested last time?"
Satoru got straight to the point with them.
Kisuke was momentarily taken aback.
He pulled out a folder: "Thanks to the materials you brought back last time, Mr. Satoru, we've basically completed the rapid construction aspect."
"But... regarding concealment, I'd like to confirm something."
"Mr. Satoru, exactly what level of concealment do you need?"
"Looking at the subsequent requirements you provided, it seems you're planning to create a secret laboratory?"
"To achieve the rapid construction effect, the base's outer walls aren't a single solid structure. Completely isolating Reiatsu would be quite difficult."
"Without a clear concealment level requirement, it's hard to find the right balance."
Hearing this, Satoru thought for a moment.
"You could roughly understand it as... building a laboratory near Seireitei, but it must absolutely not be detectable by the Gotei 13 captains. That level of concealment."
"?"
Kisuke typed out a question mark.
Even Mayuri was having trouble keeping a straight face.
Was this really a request made by a human?
After a few seconds of silence, Kisuke said, "Just to be safe, let me confirm something."
"Does this laboratory right next to Seireitei have any cover identity? Like a perfectly normal-looking shop or something?"
Satoru showed a smile: "No, there aren't any households around at all."
"Sorry, can't do it, farewell."
Without hesitation, Kisuke started to get up.
But he only managed to rise halfway before Satoru grabbed him by the neck and forcibly pressed him back down—
"Kisuke, let me be blunt!"
"Today, whether you can do it or not, you're going to do it!"
"I protest! This is bullying!" Kisuke struggled fiercely.
However, he soon discovered to his surprise that he couldn't put up any resistance against Satoru at all.
Although he had always been well aware that his strength was inferior to Satoru's,
he was at least older and had been a Shinigami for longer.
No matter how much weaker he was, he should at least be able to struggle a bit, right?
Yet, Satoru's arm was like steel reinforcement—even using both hands against Satoru's one, he couldn't budge it at all!
This guy... what kind of strength monster is he?
For a moment, Kisuke couldn't help but feel like he wanted to fuck Satoru.
Watching his miserable state, Mayuri grinned.
He loved seeing Kisuke suffer—it felt great.
However, now wasn't the time to screw with Kisuke.
If he couldn't dissuade Satoru from his idea, he might be the next one to suffer.
Amid Kisuke's "Hng ah ah ah ah!" screams of agony, Mayuri spoke up:
"Lord Satoru, I believe your request is almost impossible to fulfill."
"Unless you can develop some new technology to directly create a separate space, avoiding observation from the outside."
Hearing Mayuri's words, Satoru, who had been tormenting Kisuke, suddenly paused.
Creating a separate space...
That didn't seem impossible?
