For two days, Kisuke kept hunting these creatures of the void and capturing some of them. At some point yesterday, he felt eyes, not coming from these creatures, land on him, but they immediately lost their interest and never bothered looking at him again.
"This should be enough." Kisuke said, with blood-red gauntlets and boots and three of his 'drums' transformed into eyes, released his Shunko and returned to his base Hollow form.
As easy as he'd opened the path to the void, Kisuke also returned the same way while also transforming back to his Human form, 'Looks like Lilith has already left.'
But instead of checking over her work, Kisuke took out the capsules that contained and compressed the strange beasts, both alive and dead. While there was nothing happening to the ones alive and kept in their suspended state, the carcasses had begun to dissolve into a black gas and had started leaking out.
In a hurry, Kisuke placed numerous barriers on them and isolated the room he was in by shutting it off from the outside through physical and magical means. But after a few seconds, even with the help of his equipment, he wasn't able to detect any form of contamination and there were no signs that his lockdown was breached.
He spent a few more hours to test things out and figured that the black smoke automatically returned to the void, 'I can use this.'
After securing and storing his samples, Kisuke finally went and checked on Lilith and Ophis' work. Though, instead of coming back to that room, he went to the side that contained all the control panels and monitoring devices for that room.
With a quick check, Kisuke saw that everything was running on its nominal values, "More than a million cubic kilometers of space. That's greater than my initial estimation. Though this won't be enough, so I'll have to expand it even further after neutralizing the energy composition within it. Might take about 3 to 4 weeks."
Recalling a portion of his drone army that'd been mining for minerals in the asteroid belt, Kisuke placed them within the newly created space and let them do all the work, "By the time a bit more than a month passes, it should have expanded even more and even become habitable." He then locked everything under only his authority so that any access to the 'room' would always go through him, "Now then, I should go check that place out."

The coordinates that Athena had given Kisuke were located in the Underworld, near Hades' domain. But after a whole day of investigating, it led him to the middle of the underworld equivalent to the Sahara Desert. It took Kisuke another hour to figure out the entrance to a hidden space beneath the desert and saw some Cyclopes running around doing manual labor and the Grim Reapers supervising them.
Instead of going further in, Kisuke hid his presence and circled around the cavern, slowly making his way in while studying everything inside it. Another day had passed before Kisuke was finally able to inspect everything, including 'Tartarus' in the center covered with various barriers that prohibited those who don't have any authorization to approach.
He found an empty spot and camouflaged it before bringing out the equipment that would be used to hijack the barriers and listen to everything around him, '...Hmmm. Three days before I can lay everything down. I hope Hades, Apollo, or any other God comes to visit the site during then.'
Luckily for Kisuke, three Gods had indeed arrived at the site before he was done with everything he needed to do three days later, namely, Hades, Apollo, and Erebus. And during their 'super-secret talk', Kisuke was able to find out a few things.
First of all, Hades was indeed successful in creating artificial Devils with a few of them being at Super Devil level. And with the combined force of these artificial Devils and Grim Reapers, Hades now has around 50,000 troops under him.
It seemed that they were also planning to invite more 'Gods of Hell' that would join their group so that they'd have a better chance of succeeding when they finally commenced their attack which will start once they're able to gather most of the Longinus users in one place and eliminate them.
While it wasn't mentioned what the prisoners of Tartarus would do in this war, Kisuke already had a good idea when it was said that Apollo was the one who was going to lead the attack on Heaven to take control of the Longinus' once they separated from their owners.
What surprised Kisuke, however, was the purpose of their group and that was to eliminate the wild cards, the Longinus', and lead the Mythologies to defend against the threat of ExE seeing that no one was actually doing anything substantial against them.
"Our priority targets should be Hyoudou Issei and Vali Lucifer. Those two are the main characters that lead everyone.", Erebus muttered with a solemn expression.
Yet, Hades shook his head at his words, "Wrong. If it's possible to control them, we should strive to do so. The most concerning one is Mitsuya Kanzaki and his group, Cross Time Kiss."
"Cross Time Kiss?" asked Erebus, not knowing anything about them.
"It's a small group of Sacred Gear wielders with Mitsuya Kanzaki at its helm and possesses two of the Longinus' by himself.", Hades answered while reclining in his seat, "But the most concerning thing about this child is his world view. It's as if he wants the world to plunge into total chaos. Even though I only met him one time, I'm confident of my impression of him."
Apollo thought about it for a moment before asking, "What else do we know about him?"
"Almost nothing. Not even his history, aside from the Grigori being wary of them and the group clashing with Ajuka's faction one time. The information surrounding him is in fact, somehow less than even Kisuke Urahara... If you include all the bullshit he's putting out there to confuse everyone."
After that, they didn't have anything else important and just talked about the progress of opening Tartarus. Kisuke just waited for them to leave the next day before he also left the place, 'Alright, I'm set.'
Kisuke returned to the Belial Mansion after asking Benihime to investigate Mitsuya Kanzaki.
