In the entire Soul Society, Yamada Seinosuke's body alteration technique was indeed among the top.
Due to this, he was quite proficient in Kaido-related fields.
"The appearance of this Adjuchas reminds me of the previous Hollows..."
Yamada Seinosuke rolled his eyes, and he suddenly waved his hand, signaling the Seated Officers to temporarily leave the lab.
Once they were the only ones in the room, he then said.
"Captain Tokikaze should be aware of the Hollowfication incident, right?"
Yamada Seinosuke's eyes were bloodshot, completely different from his initial calm demeanor.
At this moment, he looked more like a maniac driven to madness.
"Naturally," Tokikaze said calmly. "If it weren't for that major incident, I wouldn't have become the Captain of the Ninth Division so quickly. Come to think of it, I might also need to thank Urahara Kisuke for his bold actions."
Yamada Seinosuke's eyelids twitched as Tokikaze considered the Hollowfication incident as a necessary step for promotion.
He chose to temporarily ignore this blasphemous statement.
The person in front of him was a noble on top of really strong. He was not someone a mere Vice-Captain could easily offend.
"The appearance of this Adjuchas is fundamentally similar to the Hollowfied Soul Reapers."
Yamada Seinosuke took a deep breath. "Born from the combination of the souls of hundreds of Menos, an Adjuchas was created. Through the transformation of 364 types of Reiatsu, a soul reconstruction is performed, infusing Soul Reapers powers into it."
"Such a creature would never be born under normal circumstances!"
Tokikaze nodded.
Indeed, during their first encounter with this Adjuchas, he had deduced that it was one of Aizen's creations.
It seemed that this guy analyzed for a long time only to come up with a useless conclusion.
Perhaps sensing the disdain in Tokikaze's eyes, Yamada Seinosuke gritted his teeth and cautiously said, "From this, it can be inferred that this Adjuchas is highly likely to be Urahara Kisuke's doing!"
"I'm sure he was not banished by the Central 46 and was still hiding in some corner of the Soul Society. This ambitious individual is highly likely to endanger the entire Soul Society!"
Seemingly worried that Tokikaze couldn't understand his analysis, Yamada Seinosuke elaborated a bit.
"Three years ago, when the Hollowfication incident occurred, I found out a massive secret related to it. Through the research and analysis of the residual Reishi of the involved Soul Reapers, there is a similarity between the Reishi of the Hollows and Soul Reaper. This is the key to Hollowfication."
"On that note, through this result, if Shinigami can Hollowfy, why can't Hollows become Soul Reaper?"
After this speech, Tokikaze's gaze towards Yamada Seinosuke became increasingly strange.
He realized that he had seriously underestimated this man.
Perhaps in terms of Kaido techniques, there was a considerable gap between him and Unohana Retsu. However, in other research fields, Unohana Retsu was probably far behind him.
"Ahem, Captain Tokikaze, do you have a different opinion on this?" Yamada Seinosuke, feeling the gaze of Tokikaze, asked cautiously.
Hadn't been Tokikaze a heir of Tsunayashiro Clan, he would never easily reveal his secrets as Tsunayashiro Clan was in charge of the Great Archive.
Yamada Seinosuke strongly suspected that Tsunayashiro Clan was aware of all of his moves.
In this case, the so-called secrets had lost their confidentiality value.
"Not really," Tokikaze replied casually. "I'm just surprised by how good you're at this stuff. From a certain perspective, it seems like the Research and Development Institute of the Twelfth Division might suit you better."
As these words were spoken, a look of undisguised disgust appeared on Yamada Seinosuke's face.
"They're just a group of nauseating lunatics."
"Ever since Kisuke Urahara took Mayuri Kurotsuchi out of the Maggot's Nest, the atmosphere in the Twelfth Division has changed drastically, completely different from when Hikifune Kirio was in charge. They have completely ruined the Twelfth Division!"
Yamada Seinosuke held a certain degree of respect for Hikifune Kirio, who was promoted to the Zero Division.
"Sorry, my emotions got a bit out of control."
Yamada Seinosuke sighed lightly, regaining his composure. "Regarding the connection between Soul Reaper and Hollows, I believe I'm not the only one who has noticed. But due to the strict orders from the Central 46 Chambers and the danger of related experiments, people refrained from conducting related research. Aside from Urahara Kisuke, I might be the only one in the Soul Society with a certain degree of knowledge about this."
Under Tokikaze's gaze, Yamada Seinosuke clasped his hands together and slowly opened them. Spiritual pressure formed lines, connecting several Reishi spheres, creating a pattern resembling the trajectory of stars.
At the center of the Reishi spheres, a red light gradually became brilliant, and a faint pressure filled the research lab.
"Cero?"
Tokikaze was surprised. "No, the aura is not strong enough."
He knew very well that Yamada Seinosuke was a pure Shinigami without any traces of Hollowfication.
"Just an unfinished product."
Yamada Seinosuke dispersed the Reiatsu and wiped off the sweat from his forehead.
What he just did placed quite a heavy toll on him.
"But if there is a more in-depth analysis and research on this Adjuchas, perhaps we can recreate a Cero in the future," he confidently said.
Observing the Vice-Captain of the Fourth Division, Tokikaze had a vague guess in his mind.
Yamada Seinosuke was deliberately showing goodwill.
Realizing the key point, Tokikaze smiled pleasantly. "Impressive, Vice-Captain Yamada. However, why are you putting in so much effort? What is it for?"
At these words, Yamada Seinosuke's expression stiffened. After a moment of hesitation, he slowly spoke:
"The research on the connection between Shinigami and Menos was restricted by the Central 46. I've seen how Urahara Kisuke ended up, and I don't want to become the next Urahara Kisuke. And the only one with enough authority to interfere with this is you, Captain Tokikaze..."
Tokikaze squinted his eyes slightly, reevaluating this Vice-Captain of the Fourth Division.
To be honest, although he despised Mayuri Kurotsuchi, from certain aspects, the two of them shared some similarities.
However, Yamada Seinosuke seemed to have more reservations.
To convince Tokikaze, Yamada Seinosuke took a deep breath, and with a serious expression, he said:
"On this basis, I can find out the answer for you..."
