Szayelaporro didn't show up; these people were just minor figures working for Tōsen, and there was no need to waste his time on them.
Knowing he could not fully control Hueco Mundo, Szayelaporro became completely absorbed in his research on perfect life during this period.
Following Tōsen, they arrived at a room that was very clean and tidy. There was only one instrument and a huge jar, inside which the Void was located.
He was asleep; the Reiatsu emanating from him, Vasto Lorde-class Menos Grande, was enough to make the group tremble.
"Such powerful Reiatsu! Can I instantly become stronger by fusing with it?" Taze Kiriko exclaimed excitedly.
Tōsen glanced at him sideways and said indifferently, "Not necessarily. If the soul cannot withstand his power, it will collapse and die, turning into Reishi and dissipating."
"Uncle Taze, don't think too much about it. Your Reiatsu level is far beyond what you could possibly achieve with a Hollow of this caliber." Ryūsaki also smiled and reminded Taze not to dream of swallowing an elephant whole.
"Are you jealous? I've heard that Hollowfication is a deadly poison for your race." Taze had been a member for over a year and knew a lot about it.
"I'm not interested in taking risks for such a small improvement. With the talent of our race, we can all reach the strength to fight the Captain with normal growth."
Ryūsaki's words left Taze speechless. They had sparred many times, and Taze had never won against Ryūsaki.
Ryūsaki is indeed unable to Hollowfication due to his own reasons. If he were to forcibly merge with a Hollow, his power might actually be damaged. The so-called impact on his family's bloodline is only a secondary concern.
Quincy, who primarily use Reishi in combat, will have little impact on their power unless they use their own methods to transform Hollows into Reishi and then absorb them into their bodies for a temporary power boost. Once the Hollows' Reishi are used up, they will be largely unaffected.
Any Reiatsu from a Hollow will affect them, such as being severely injured by a Hollow or having Hollow Reiatsu remaining in their wounds.
Quincy are too sensitive to Reishi and are completely opposed to Hollows. There is no balance point when Hollows merge with them; they will only fight each other until they all head towards destruction.
Aizen actually hoped that Ryūsaki would accept Hollowfication as a pioneer of Quincy Hollowfication Experiments, but Ryūsaki wasn't stupid and politely refused Aizen, saying that he would only take the risk when the experiment was under control.
Two technicians with remnants of masks on their faces entered, bowed to Tōsen, and then helped him operate the instrument connected to the tank.
Under their manipulation, the nutrient solution inside the jar began to shrink, forming a concentrated mass that surrounded the sleeping Menos Grande. The concentrated mass continued to shrink until the Menos Grande itself became an egg the size of a basketball.
Ten needles connected to tubes appeared, slowly piercing into the egg, extracting its power and transforming it into Reishi.
"Don't worry, your Reiatsu has been injected into its body for a long time. At the very least, it will be close to you. You need to win its favor in your Inner World."
Tōsen began explaining to Ginjo the process of acquiring Hollowfication power, while Ginjo was placed on an operating table nearby and secured, with ten needles slowly approaching him.
After confirming the location, the needles were inserted into several important acupoints on Ginjo's body, and the Reishi particles were injected into his body.
"You all wait here! Don't touch him, he has at least an 80% chance of succeeding..."
After leaving those words, Tōsen turned and left. He hadn't been to Hueco Mundo for a while; he still had a lot of work to do, such as keeping up with the progress of other Hollows.
A male technician with remnants of a mask around his eye was writing rapidly in a notebook, while a woman with a barely perceptible ear was constantly typing on a keyboard.
Ginjo's Reiatsu also began to change. Originally, the power representing the Soul Reaper was mixed with the power representing the Hollows, but now the power of the Hollows suddenly surged, breaking the balance.
A mask revealing closed teeth quickly covered Ginjo's face, screaming as it opened and closed, "Ughhhhh... Roar!"
In just a few seconds, Ginjo turned into roars.
The violent and rampant Reiatsu emanated from the protective shield on the operating table. Coupled with the terrifying mask and the Menos Grande that seemed to tear Ginjo's body apart, Taze and Jackie took a few steps back in fright.
Ryūsaki remained motionless, squinting as she observed carefully, while Aura's bright, lively eyes were also filled with curiosity.
Tsukishima was very nervous. He had been given a task by Ginjo: when Ryūsaki judged that Ginjo's body could not withstand it, Tsukishima would go up and use the 'Book of the End' to embed a 'never-injected Hollow' past into Ginjo.
"How is it? Is Ginjo capable?" Tsukishima whispered in Ryūsaki's ear.
Ryūsaki observed that Ginjo's physical condition was normal, and raised an eyebrow Kaido, "You should ask him that yourself. How can a man say he can't?"
"Wasn't it for you to make the judgment?" Tsukishima's heart sank, and he gripped the small Bookmark tightly in his hand.
Aura laughed, "Don't tease Tsukishima. He's very concerned about the boss and will take it seriously."
With a sigh, Ryūsaki could only say seriously, "He's alright for now, but the structure of his Reishi is beginning to change."
He could see at a glance that the Reishi of Ginjo were changing, constantly intertwining and combining with each other. This meant that Ginjo would not collapse, but would only become stronger after the Reishi merged.
Of course, there is another possibility: the consciousness controlling this stronger body is no longer Ginjo, but has become that unknown void.
After roaring for a few minutes, Ginjo's raging Reiatsu began to subside slowly, his mask fell off, and finally, as the whites of his eyes returned to normal, Ginjo finally took the first step and successfully Hollowfication.
"The Hollowfication is over, he succeeded." One of the staff members, whose face was still partially masked, reassured the group before turning and leaving.
Unlike the methods Hirako used to control Hollowfication, Ginjo's fusion method was the culmination of Aizen's years of hard work. Aizen eventually entrusted this project to Tōsen for further research, while Ginjo focused on improving it to suit his own needs...
Except for Tsukishima, Ryūsaki and the others didn't stay in the room any longer; they all went out with the technicians.
When the technicians went into a nearby Laboratory to report to Tōsen, Taze, unable to contain his surging power, followed them...
"Taze seems a little dissatisfied with you!" Aura sensed the subtle tension between the two.
"That's normal. He 'Taze very confident in his own strength, and I've been dominating him in training, so it's inevitable that he'll feel jealous. It's a very common human emotion," Ryūsaki said with a smile, revealing Taze's inner thoughts.
That's right, just as he said, Taze wouldn't allow a little brat to keep crushing him.
However, Ryūsaki didn't take this minor conflict to heart. Based on Taze's basic skill level, even if Hollowfication, he would still be nothing but trash.
The soul has its limits; if these limits are exceeded, it will collapse. The level of Hollowfication that Taze can withstand within his soul's limits, even if successful, would at most be that of Captain-level.
Taze followed the staff to the adjacent Laboratory. After the two finished their reports, Tōsen finally said to the silent Taze, "Is Ginjo alright now? Is there anything else?"
Taze bowed slightly. "I would like to ask Tōsen to also tailor-make a Hollow for me, as I also wish to obtain the power of Hollowfication as soon as possible."
With an expression of certainty in his eyes, Tōsen said, "So that's what it is!"
"It's a minor issue. We've been working on it since you agreed to Hollowfication, but your own strength isn't enough, Artificial Hollow you can inject won't be very powerful."
Upon hearing this, Taze paused for a moment, then said, "I already knew that, which is why I want to merge with the Void that possesses the ability to absorb, and become a new soul..."
Tōsen smiled and was about to speak when Ryūsaki, who was eavesdropping outside the door, praised, "A smart person. Knowing that his talent is definitely not good enough, he wants to evolve by absorbing others like Hollows. That's a good idea."
"We call this kind of Void that retains the ability to devour others 'Growth-type.' It's not absolutely safe; it's currently under research, and it's very likely that it will be replaced by other consciousnesses during evolution."
As Tōsen spoke, he pointed to the Hollow currently in the jar and continued to the two, "This is a Vasto Lorde in its early stages. It has a strong potential for evolution, and I've equipped it with the ability to freely choose its host."
"The next step will be to conduct experiments in the World of the Living, letting it attack and devour Soul Reaper first. If a suitable target appears, it will transfer to that target and continue to evolve. What I need to do is observe the rate of its evolution after it transfers to a new host."
Ryūsaki looked over and saw that the Hollow sleeping in the jar was entirely black, except for its white head mask with two horns and hair. The originally dark hole in its chest was now blocked by a wriggling mass of matter.
For some reason, this phantom gave him a feeling of unease.
