Just like with Yamamoto and his group, Kisuke also showed his experiences to Aizen, albeit, a little bit different from them.
Unlike Yamamoto's group, what Kisuke needed to give Aizen was not a reason to support him, but an avenue for him to step out of a certain being's shadow and prove that he could be free from any will being imposed upon him.
Of course, he also made sure to show that he doesn't have any intention of destroying Soul Society, the Human World, and Hueco Mundo like Yhwach wanted to since like the war more than a decade ago, Aizen would be the one who'll stop him.
"A giant hole, huh? Couldn't you do that on your own?"
Kisuke didn't answer immediately and thought about it for a moment, "I can, but I'd like to be free at that moment."
"I see..." Aizen then finished his cup of tea before standing up, "Then I'll come to you when the time is right."
"You're not going to ask for more information?"
"About what? About you communicating with that man through convoluted ways? Or the fact that you're not manufacturing those bodies enough to supply everyone who'll need it?"
Kisuke chuckled, "So you already understand the situation pretty well."
Aizen then turned his back and started walking away, "You're insulting me if you really thought that I couldn't understand any of that after all those hints you gave me."
Kisuke thought that he'd leave the Muken through the entrance but Aizen suddenly stopped walking and slightly turned his head towards him with a mocking smile, "I don't really care whether you succeed or not since I'll be able to find the way out myself. However, let me remind you that you're severely underestimating Ichibei Hyousube."
As soon as he finished his words, the space in front of him opened up and instantly gobbled him up, disappearing from the prison that held him for a 'short' amount of time.
Kisuke's eyes immediately widened when he saw that, 'He already mastered and can already use that near-instant teleportation?'
But soon enough, Aizen's words resounded in his head, 'I'm severely underestimating him? What else am I missing?' Since they're technically enemies, Kisuke is not surprised that Aizen wouldn't provide him with useful information, 'But when he says something, it's surely something I can't discard.'
Kisuke cleaned up and placed a body double that'll disguise as Aizen on the pillar. Once he was sure that it wouldn't be discovered for some time, Kisuke also left while thinking, 'The bug that I left in the Soul King Palace still indicates no movement from the Royal Guards. But I guess I just can't expect them to move the way I'm initially predicting now.'

Kisuke returned to the log house and saw no one in it. With a quick scan, he found out that they were all within his lab.
As soon as he entered the facility, he was greeted by Ophis and Lilith who came running towards him, "I'm sorry for pulling the both of you out of the Seireitei. It's about time for us to get busy and I don't want the two of you to be burdened by potentially hurting your friends." Kisuke softly told them while patting their heads.
Ophis shook her head and said, "We were able to say our farewell and it's not the last time we'll meet."
"That's true. After all of this is over, ask them to hang out with you."
Ophis and Lilith smiled happily and nodded, "That's a promise."
"Of course."
Kisuke then turned to the group who were looking at him with curiosity, "How did it go, Nimaiya-san?"
"Naturally, it's a success! Though some credit goes to your toys. They are very convenient to use. Give some of them to me." Ouetsu replied while tapping on the table where everyone's Zanpakutowass was placed.
"You can have all of them." Kisuke replied while walking towards them and scanning the group. The movement of Magic Power around them is very intentional, signifying that they mastered the art of its manipulation to some degree, 'Except for Unohana-san and Katori-san... It seems that they got a different treatment.'
"So what seems to be the problem? Why are your blades lined up on the table."
Ouetsu also returned his attention to the table and rubbed his chin, "It seems that I'm too successful."
"What do you mean?"
"Our Zanpakuto are rebelling." Furoufushi answered Kisuke.
Kisuke instantly became very concerned, "...Even the old man's?"
Yamamoto nodded. But contrary to Kisuke's expectations, Yamamoto actually had an interested smile on his face, "But it's not really a bad thing. I just have to subdue Ryuujin Jakka."
Upon that statement, the Shinigamis around him immediately remembered why they would have to subdue their Zanpakuto from time to time. It's because their blades gained power that's beyond their current capabilities.
Furoufushi grinned and grabbed her Zanpakuto, "Alright! Enough of that Magic training or whatnot. I'll be out for a while. Don't look for me."
She didn't wait for anyone and immediately darted towards the exit before using Flash Step to disappear.
Chika sighed and chuckled, "I guess that's the schedule for everyone." He also grabbed his Zanpakuto and left the same way as Furoufushi.
Batsu'unsai silently grabbed her Zanpakuto and left while Unohana smiled softly while saying, "I hope I can learn that healing technique next time." before getting hers and leaving.
"Ask Tanis-chan. She's an expert regarding it." Kisuke replied before she disappeared.
"I guess I'll go too. Maybe I'll scout the [Chained] while I'm at it." Gin also soon left.
Juushirou turned to Yamamoto and said, "Old man Yama. Make sure to go as far as possible. It's not going to be fun if you, of all people, lose control."
"You don't have to remind me."
Juushirou chuckled and before he left, he turned to Kisuke, "Urahara-san, I hope that you won't give Kyouraku too much trouble that he's unable to handle it."
"He's going to hate me but it's nothing he can't handle."
"I see. Thank you."
Choujirou wanted to follow the old man but he knew he couldn't do that so he just silently left.
Yamamoto finally grabbed his Ryuujin Jakka and looked at it for a while before turning to Kisuke, "It's going to be an upheaval. Don't expect Hyousube Ichibei to be trapped. Unlike the rest of the Royal Guards, he's someone unfettered."
With everyone picking up their blades, Ouetsu made his way back to his workshop and this made Kisuke ask, "Going back to work already?"
"I have to make empty Asauchis so that I don't have to reforge a Zanpakuto whenever someone needs it to be converted. And please prepare that body for me. Forget about me temporarily using it."
Kisuke creased his brows, "Why?"
"It's something I realized after forging those blades... That man is already aware of my betrayal."
