Two days later.
In the laboratory.
"This power.."Gantenbainne lay on the operating table, similarly covered in various wires, awaiting the results of the final test.
"Hoh hoh, your cells have completely transformed into entirely new cells."
"Congratulations, you have become one of the kings of Hueco Mundo a Vasto Lorde." Mayuri Kurotsuchi smiled, seeing the data detected on the screen before him.
What a huge harvest.
With this experimental data, Mayuri Kurotsuchi had too many research achievements that could be improved, and even his own body, as well as Nemu Kurotsuchi's body, could undergo a certain degree of re-modification.
And this was all brought about by Kuchiki Shinji.
His palm brushed across his chest.
The mechanism controlling his life, left by Kuchiki Shinji, was located there.
But now, Mayuri Kurotsuchi was not unwilling to accept this mechanism he even felt that its existence was truly brilliant.
Because only in this way would Kuchiki Shinji trust him.
And only then would Mayuri Kurotsuchi be qualified to participate in Kuchiki Shinji's experiments.
"The feeling of rebirth, the feeling of power constantly surging forth, it's truly wonderful." Gantenbainne sat up, tearing off the wires on his body the crackling currents running wildly could not cause him the slightest harm.
After evolving into a Vasto Lorde, their defense once again increased geometrically.
Now, Gantenbainne finally understood what kind of power the top four Espada possessed.
"you're not satisfied with just this, are you?" He said to Cirucci.
"I will never be satisfied."
"As long as I can continue to evolve, I'll do anything." She looked at Shinji, and at Nelliel.
A hint of jealousy flashed unnoticed in her eyes.
Since she participated in this experiment, and Shinji and Mayuri Kurotsuchi discussed many things in front of them, Cirucci was very clear.
She and Gantenbainne were just the beginning of the plan.
The two of them served as a safeguard for Nelliel.
As long as Cirucci and Gantenbainne successfully evolved without any side effects, Kuchiki Shinji would immediately initiate a new evolution, allowing Nelliel to transcend the Vasto Lorde-class and become the only Menos Grande to surpass a Vasto Lorde.
Cirucci was filled little jealousy, feeling that she had seen through Nelliel's true intentions, she clearly knew that Kuchiki Shinji had the ability to make Menos Grande evolve, which was why she stayed by Kuchiki Shinji's side.
"Tsk tsk, how greedy, but it's understandable, the instinct for evolution is what Hollows pursue." Mayuri Kurotsuchi chuckled, walked to the other side, and pushed a switch.
Then, a cylindrical Training vessel slowly rose, and Szayelaporro's corpse lay floating gently in the compartment filled with nutrient solution.
To ensure the "activity" of the corpse, Mayuri Kurotsuchi had put in a lot of effort.
"Szayelaporro, that bitch, I will crush him little by little with my own hands, sooner or later." Looking at Szayelaporro's corpse, Cirucci's eyes suddenly turned cold.
Her grudge with that madman Szayelaporro wasn't a day or two old.
Szayelaporro, that madman who liked to insult her and constantly called her a prostitute Cirucci would have killed him long ago if she hadn't been concerned about her own strength.
But now, she was different having evolved into a Vasto Lorde, she possessed a level of power entirely different from before.
"Since the experiment has been successful, and Cirucci and Gantenbainne have both successfully evolved without any adverse reactions, Nelliel's evolution can now officially begin."
Shinji stood up and looked at Mayuri Kurotsuchi "Give me a room, a completely sealed room."
"No one is allowed to enter or approach during that time, until I come out or call you."
Hearing this, Mayuri Kurotsuchi was slightly surprised "Do I not need to preside over this experiment?"
This was an experiment to break through Vasto Lorde and evolve to an entirely new dimension!
Mayuri Kurotsuchi's thirst for knowledge kept telling him in his mind that he had to participate in this experiment, he had to join this experiment, to personally witness the birth of a Menos Grande beyond Vasto Lorde.
But reason was telling Mayuri Kurotsuchi to listen to Kuchiki Shinji.
His life was completely in Kuchiki Shinji's control.
Moreover, as long as he continued to work for Kuchiki Shinji and gained enough of Kuchiki Shinji's trust, then even if he couldn't participate in the experiment today, he would sooner or later have the opportunity to participate.
"Do as I say, No one is to come in, otherwise, you will truly die." Shinji said very seriously.
Nelliel's evolution would not be a minor affair like Cirucci and Gantenbainne's.
Shinji was going to directly use the Hōgyoku to Nelliel's evolution, rather than extracting part of the Hōgyoku's power and using it through secondary injection.
Shinji did not want anyone to know about the existence of the Hōgyoku.
And among those present, besides Nelliel, Shinji trusted no one else.
So this was not a warning, but simply a statement of fact.
"Tsk, what a pity."
"You don't need to worry about what's outside, With me and these two newly evolved Vasto Lorde Arrancars, no one will disturb you."
"Follow me." Mayuri Kurotsuchi pouted and walked towards the wall ahead.
He inserted his Zanpakuto into a crack.
The wall slowly opened, revealing a dark passage.
"This is a secret room I left many years ago."
"It's a warehouse used to temporarily store some forbidden research items in case of extreme necessity."
"The surrounding walls have all been reinforced with special materials even a Captain Zanpakuto strike cannot cut through them in one go."
"So it's absolutely safe."
Tapping the metallic-sheened wall in front of him, Mayuri Kurotsuchi looked at Shinji, the corners of his mouth upturned "Then, Captain Shinji, I wish you success in helping Vice-Captain Nelliel evolve in advance."
The Zanpakuto was pulled out, and the door gradually closed.
Mayuri Kurotsuchi's half-smiling expression completely disappeared.
In the darkness, a large number of lights immediately illuminated the entire warehouse.
This was a medium-sized warehouse, about several hundred square meters, and because it hadn't reached what Mayuri Kurotsuchi called "extreme necessity," it appeared empty, with nothing inside.
Barrier after Barrier opened.
Finally, white light flashed in Shinji's eyes.
Super Reiatsu Wall!
The heavy Reiatsu Barrier completely covered the Barrier, creating a double safeguard.
"Are you ready, Nelliel?"
Then, Shinji took a breath and looked at the green-haired girl beside him, who was holding his arm and resting her head on his shoulder.
"Mhm mhm, I'm already ready." Releasing his hands and standing in front of Shinji, Nelliel's eyes were gentle "After the evolution is complete, will you be the first person I see, Shinji?"
Hearing this, Shinji nodded "Yes, I will stay here these days until your evolution is complete."
Shinji had already informed Matsumoto Rangiku and the Captain Commander.
So, even if he disappeared for ten days or half a month this time, there wouldn't be any problems.
All preparations were complete, and the Hollow's evolution was thoroughly proven to be without any danger or side effects.
"Then Shinji, let's begin."
"I will definitely Succeed so I can help Shinji even more." Nelliel smiled gently, looking at Shinji's slowly extending hand, and said softly.
Then.
A faint, almost inaudible hum sounded.
The power of the Hōgyoku, through Shinji's palm, continuously poured into Nelliel's body.
The evolution, Had begun.
Instantly.
Nelliel lost consciousness and floated directly in the air.
The Reiatsu around her instantly compressed to an astonishing degree, and within the constantly compressing Reiatsu, Nelliel rapidly transformed.
"Indeed, my thinking was correct even if the Hōgyoku is used, as long as the quality and purity of the power output from the Hōgyoku are controlled, the evolution will manifest in different ways."
Unlike the defective products used for Cirucci and Gantenbainne, those were merely diluted and degraded products of the Hōgyoku's power.
But this time.
What Shinji used for Nelliel was the true power of the Hōgyoku, its purest essence.
The perfect power released by the perfect Hōgyoku also brought about a perfect evolution.
Standing in front of Nelliel, Shinji could clearly feel Nelliel's Reiatsu growing at an extreme speed.
"Evolving again, what will a Vasto Lorde Hollow ultimately evolve into?" Shinji's gaze was deep as he withdrew his hand.
At this point, there was no need to maintain such an unnecessary action.
His chest felt scalding.
The light emitted by the Hōgyoku even penetrated his shinigami uniform and white captains haori coat, illuminating the entire warehouse, emitting an exceptionally mysterious fluctuation.
Invisible but real tentacles constantly extended, but this time the Hōgyoku actively bound them.
With a master, it no longer needed to peek into the hearts of surrounding creatures and fulfill their wishes.
The Hōgyoku only needed to fulfill its master's wishes and demands.
"The fusion with the Hōgyoku is deepening rapidly." Shinji clutched his chest, his palm immediately feeling the Hōgyoku's high temperature.
In just this short amount of time.
It had already increased to a noticeably perceptible degree.
Developing the Hōgyoku's power and using the Hōgyoku's power continued, as always, to promote Shinji's evolution.
And helping Nelliel evolve, required the Hōgyoku to release a large amount of power and resources, which directly caused Shinji's fusion rate to increase rapidly.
"Judging by the current speed, it's likely that not long after Nelliel evolves, I will also be nearing the.. 4th fusion stage." Shinji looked at Nelliel in front of him, the corners of his mouth gradually turning up..
Seven days later.
In the Tenth Division Barracks, in the captain's office.
"Today is another busy day." Matsumoto Rangiku, sitting on a chair, stretched lazily.
Rukia's eyes sparkled, filled with envy as she looked at Matsumoto Rangiku's chest and her alluring body that made one blush.
Then she looked down at her own flat figure.
Instantly, she felt her life turn dark.
She felt inferior, truly inferior.
This was too much of a blow.
"Huh, why did Rukia-chan's expression suddenly become so dejected?" Matsumoto Rangiku propped her chin on her hands and blinked as she asked.
"I also want.." Rukia mumbled weakly.
"So Rukia is bothered by that." Matsumoto Rangiku shook with laughter as she comforted her "Don't worry, you're still young, you'll have it all later."
"Besides, being tiny like this is also very cute."
Matsumoto Rangiku gently comforted her, unable to resist walking over and hugging Rukia, pinching her face.
"Don't do that, Miss Rangiku, my hair is getting messy."
Whenever Matsumoto Rangiku and Nelliel appeared in his sight, Shinji's gaze would always focus on them.
Through that she understood, Shinji's type.
"You really care about Captain Shinji." Matsumoto Rangiku couldn't help but imitate Shinji.
Rukia's face suddenly turned crimson, her body seemed to freeze, unable to move, only allowing Matsumoto Rangiku to pet her.
"Speaking of which, where did Captain Shinji go to? He hasn't made a peep for a whole week." Matsumoto Rangiku looked out the window, her eyes filled with worry.
Although Shinji had specifically told her that he would disappear for a while this time.
She still couldn't help but feel a little anxious.
Could it be that something happened?
Thinking of this.
Matsumoto Rangiku put her hands under Rukia's armpits, turning her to face herself
"By the way, Rukia, did Captain Shinji tell you where he went to?"
"Always being mysterious, leaving us two here to handle division affairs for him."
"When he comes back, I'll definitely make him pay dearly."
"I want to go to the Human World to drink, and without ten or eight times, don't even think about appeasing me."
"Girls who aren't satisfied can do very terrifying things." Matsumoto Rangiku snorted coquettishly.
Rukia: "???"
What kind of shocking words were those?
Kuchiki Rukia gave her a blank look, considering that she was truly no match for this 'fallen' older sister type, and silently chose to follow her heart.
-On the other side.
In the warehouse beneath Mayuri Kurotsuchi's secret laboratory.
Shinji suddenly opened his eyes.
The Hōgyoku's light began to dim, eventually extinguishing, no longer releasing any power or resources, silent as if asleep.
Ignoring the changes in his body, and temporarily not paying attention to the greatly increased fusion rate, which had almost reached its critical peak.
Shinji looked forward.
Nelliel, who had shown almost no change for seven days, suddenly began to release a large amount of astonishing Reiatsu from her body.
Bang! Bang! Bang!
All the electric lights exploded instantly!
A large amount of current was drawn by an invisible force, constantly leaping out of the circuits, but then instantly annihilated.
The air temperature rose instantly, and gusts of wind constantly blew in the confined space.
Even the Super Reiatsu Wall that Shinji had set up long ago was greatly impacted.
Pale red Reiatsu flickered continuously in the dim environment, like a beating heart.
The quality and quantity of that Reiatsu were hair-raising, almost containing terrifying energy capable of destroying everything, completely surpassing the limits of a Vasto Lorde!
That was a brand new realm!
Shinji's lips curved into a smile: "It's finally starting!"
