Minutes after dismissing himself from the laboratory before he left out the doorway he placed a Caja Negacion in his hollow hole. The dimensional energy emitting from the cube immediately starts to envelop Izeel and then collapses inward on itself trapping him away into a pocket dimension. Although, the device used upon himself differed greatly from the ones he had made for the other current Espada in the God-King's army. This specific Caja Negacion wasn't tailored to imprison him, but quite the opposite as he got sent into a pocket dimension he constructed to conduct his top-secret experiments on and where the vast majority of his most valuable research and inventions were stored at. What he kept around in his laboratory inside the confines of Las Noches were simply replicated experiments and minor works he didn't care to lose, and after the incident with Elliora, this is also where he kept the large container of the Soul King's blood in he still used for a lot of his research. Those of the Arrancar who was paying attention would suddenly feel all of Izeel's reiatsu completely vanish away.
Walking down the corridors of his laboratory on the left and right of him holographic display screens popped up to monitor the inhabitants of Las Noches and Hueco Mundo at the current moment. On one screen it displayed the room of Emilia where it seemed an unexpected visit from Abraam looking to reclaim his rank back as Espada. A much larger screen appeared in front of him with the most alarming information displayed was the Primera and Cero Espada leaving to the World of the Living to cause who knows what amount of destruction. Another screen to his right happened to show the incident he left back in his other laboratory with Helliodoro and Guillermo conflict of opposites of personalities had taken place. Unfortunately for Guillermo his naivety ultimately ended up being his downfall where he desired to make friends and thought they were going to foolishly play a game together, while the other only wished to squish them like a bug. The fight seems to have ended for the time being, and before he carries on about that outcome he is confronted by one of his artificial hollows he keeps things running in this domain when he is absent.
"Master the preparations are ready and are going ahead of schedule for your surgical modifications. The Gigai production is exceeding our expectations, and all battles at the current moment are being recorded as you requested."
"Excellent inform them I will be there momentarily, I have some other incidents to attend to real fast. Prepare one of the special pods I set up for the worst-case scenarios."
"A-are you sure about that Master this will set back our Hooleer resources significantly you amassed over the hundred years."
He didn't bother to acknowledge the questioning of his orders with words but a singular gaze that if he spoke out of place again, it would be their last words. Getting the clue from their creator the hollow nodded his head and then excused itself away to attend to what is ordered to get taken care of. Making a simple gesture in the air the same dimensional energy enveloped him once again before it unraveled leaving his figure ominously standing directly in front of the Vasto Lorde's body left mangled within his lab. If Helliodoro had the brains to understand how bad a decision it was to leave such a being splattered in the hands of the mad scientists, he would have realized what a blundering mistake was made. Here Guillermo remains to wait for Izeel to exploit for his nefarious purposes and plans, as he pointed at him seemingly speaking to himself.
"Take only what you need for the resurrection protocol, this is the perfect specimen to be our first test trial."
Crawling from out his coat sleeve is his fully matured Radiestesia Bichos; a large snake-like caterpillar appearing creature. It slowly moved down on the ground to Guillermo's body devouring parts of his body, but namely, the brain matter splattered all on the floor consuming a large portion of it, and already began the process of storing the memories and history it gained for later. Once it finished gathering what was needed from him, it crawled its way back up his sleeve and coiled up in wait for its next task while Izeel kneeled with a mischievous gaze on his face looking at this delicious feast. The opportunist he was wasted no time taking large bites of what remained of the Vasto Lorde Guillermo making sure to devour every last bit of him. Every bite he consumed with savagery his reiryoku only grew stronger by the second, but even in this, he kept his reiatsu concealed just like when he consumed parts of the unconscious Elliora. One by one the Arrancar made this mad scientist stronger having consumed parts of the former Esquisa Alfa and Mudo, the Privaron Espada Elliora, and now the newest to his collection Guillermo.
A loud belch escaped him once he finished savoring the brain matter for last, then returned to his well-poised self cleaning up after his meal. With that taken care of, he transported himself from out of Las Noches back into his laboratory located in the pocket dimension stopping briefly to enter into a large chamber room where he stood upon what came of his former ally Alfa and Mudo. Both separated from one another into two stasis chambers with multiple mechanical devices keeping them in a state of agony as they became nothing more than a constant resource to supply his lust for knowledge. The stasis chambers carving chunks from their flesh being used to hasten his creation of Hooleer tenfold, but most noticeably his production of an experimental substance.
It was through his research on figuring out ways he can experiment with the nucleus of Arrancar hollow powers sealed away in their zanpakuto, that he came across another discovery. Using some of the harvested pieces from Alfa and Mudo when exposed to direct radiation of pure hollow reiryoku and reimyaku from Hueco Mundo, and using a single drop of the Soul King's blood produced a potent consumable more closely related to a drug. When an Arrancar eats this it grants them an incredible boost in their powers and replenishes their spiritual energy, but if the consumer is not strong enough to contain the power surge it causes their reiatsu to burn their soul away, and minor side effects severely damage their reiatsu vents. Other side effects are unknown due to so far his most recent specimens did not survive long after consumption of this super drug. After his little visit to them, he went about his way with the sounds of their screams of pain and anger echoing behind him into his medical room where multiple artificial hollows of his creation awaited surgery, but for whom?
One of the artificial hollows pulled out a large syringe extracting the DNA of Guillermo from Izeel's creature coiled around his neck. Afterward, this DNA was placed into a special pod slightly similar to the one he used to heal the brain-damaged Elliora, but to compare the two capabilities was an understatement. First, the machine was fed into a different container where Guillermo's body was being reconstructed and a few of the hollows surgically began to place in many of the organs he had at his disposal. The next step was prepping the brain for
the memories stored within his Radiestesia Bichos with a slight few modifications being done to his brain. With Izeel's vast knowledge of both hollow and Arrancar, he grinned mischievously thinking how Mayuri was not the only one who managed to discover how to resurrect Arrancar with the majority of what he needed is contained in the DNA code of the Vasto Lorde just waiting to be solved like a complex puzzle.
As much as he hated it, the breakthroughs of Aizen's discoveries had helped him uncover the secrets he needed. However, he did not plan on letting a shinigami best him in his field of study finally discovering some breakthroughs that had long eluded him until recently. Climbing into a chair after he removed his coat and shirt, one of his medical programmed hollow approached him and started to use a scalpel to cut into his back. Using the research notes from Aizen's experiments on hollowfication and hollows himself one that piqued his interest the most was how he created a hollow capable of destroying shinigami zanpakuto. After spending countless time recreating this hollow enhancement he created, he now begins to undergo the procedure on himself adding this unique modification to his collection. Around this time is when he got the alert of a new confrontation that just happened to take place soon after giving the command for them to pull up all incidents happening in Hueco Mundo on the screens while he was undergoing surgery.
With all the current fights taking place being shown to him he made sure to watch them carefully as they played out, although because of recent events with Kassius being set free he needed others' help to come up with a plan to deal with this unsure on how long Max would be gone. Unsure where some of the other Arrancar or Espada dwelled as he scanned for their spiritual energy readings, at the current moment what he was left to work with was: a brat of Arrancar, Yandiel, Abraam, Cordelia, and Emilia. This revelation caused him to need to intervene in their childish dispute going on knowing trying to stop the fight between Helliodoros would not be worth it, because of his lack of intellect and simple mind. Trying to recruit him for the cause would only cause matters to get worse, so right now with him being occupied by another was the ideal outcome. Placing a neurotic device on his head, he activated one of his reigai as it stepped forth from the capsule leaving him physically incapacitated while in control of it. The reigai entered into a portal where it unraveled the dimension placing it directly outside the door of the Espada Emilia currently in the middle of battle still with Abraam. The reason why Abraam started the fight was very easy to figure out from their prior talk, yet it seemed once Max left Hueco Mundo everybody forgot their God-King's words on stopped focusing their energy on trying to kill one another and focus it on their real enemies. The entire notion that Abraam needed to kill another to regain his place as Espada was foolish to someone like himself. Unless somebody had taken his former seat or he wished to claim Emillia's place this was unnecessary, especially because in his eyes Max said to earn it back, but how does weakening their forces do this? More importantly, the way how he gained that seat was not through Max's power but Abraam's confidence and power. Did the God-King rob this confidence and power away for him or was it all just a bluff? This is why Izeel acted no differently from when he proclaimed himself as Espada and did not let this deter him from his work. The three Arrancar soon sense the presence of Izeel making his appearance with his scalpel polearm drawn, lightly being twirled to the left of him.
"There are more pressing matters to be concerned about, but if you two wish to continue this pointless display of power then I will be happy to put end to this quicker."
Meanwhile, the actual Izeel still under surgery watching everything taking place in his pocket dimension grumbled to himself. His gaze left away from the monitors momentarily to stare at the beautiful prized possession before him. What Max thought he had destroyed remained because he accomplished exactly what he promised to do; create something indestructible to house the Hogyoku. The God-King forgot the Hogyoku casing Izeel designed with the sole purpose of being splintered into different shards and forming back together as a whole if needed, so when he crumbled it up into pieces this was no different. While he gazed at the Hogyoku off to the side another one of his most recent projects he took great curiosity in had scans and different readings been running on it, with a small hint mentioning of a singular hollow named "White".
"You need to feed on the souls of 200 souls rich in reiryoku to come alive? Maybe it's about time we pay a visit to the World of the Living soon my beautiful.~"
