By rushing without using their Reiatsu-Ki aside from strengthening their bodies so that they wouldn't provoke the Dungeon any further and avoiding monsters while also searching for a suspicious or great spot for teleportation magic, they got back on the surface two days later. But before coming out of the Dungeon, Yoruichi and Kisuke stopped on the 4th floor and looked for a secluded area.
Once both of them settled down, Yoruichi helped Kisuke unwrap his bandages while he takes out a 5mL syringe containing a liquid with intertwining red and white colors.
While unwrapping her bandages, Yoruichi asked, "Can you tell me now what you found out?"
Kisuke didn't answer immediately as he first arranged his thoughts before speaking, "I've confirmed that the Dungeon is alive but I also found out some surprising things..."
"Like?"
"The Dungeon isn't a single entity."
Yoruichi finished unwrapping the bandages and furrowed her brows, "What do you mean?"
"There are at least two intents or wills in this Dungeon and from what I can tell, those intents don't get along. Of the two intents, one is predominant while the other one is very weak which is why I didn't notice it immediately." While explaining, Kisuke injected the medicine he developed using his own Hollow part to regenerate the lost limb. While it's still an experimental drug that only works on him without any side-effects since it came from him, Kisuke used the same drug on Sona when her limbs were severed because of the poison due to lack of options. Because of that, he's keeping close attention to Sona's body condition by examining her almost every day.
From Kisuke's words, Yoruichi formulated a few guesses of her own, "Are you suggesting that there's a battle of wills in the Dungeon itself? And the dominant one is the one producing these monsters which are hostile against people?"
"Right... But I don't have any solid evidence yet... However, if I'm correct, then somewhere in this Dungeon are monsters that are produced by the second weaker will, and chances are the monsters of the first dominant will are hostile against them. If they're hostile against people, I don't know... I don't have enough information." As he speaks, the stump on his shoulder started bubbling with a white matter before it slowly grew into an arm in Hollowfied form. Once it regenerated completely, the white shell started peeling off, revealing his new unblemished arm. However, a few seconds later, crimson flame-like veins started crawling on his skin and his arm's temperature started rising rapidly, 'I guess it isn't that easy... It'll take a few days to fully heal this.'
While Kisuke is taking out a new set of bandages and applying heat resistance magic on it, Yoruichi talked, "So we have to watch out for any strange monsters that will appear, huh... Let's leave that with others." After Kisuke finished applying enchant magic on the bandages, Yoruichi helped him wrapped his arm again, "Anyway... Should we continue our trips to the deeper floors?"
"No... Even if we're in our full strength, the Dungeon, which can spawn something like those is more than we can chew if we accidentally go against it. So for now, let's focus on recovering our strength and leveling up. If we can reach around level 8 or 9, we should be able to have a strength that is comparable to what we can use when we're using our Reiatsu-Ki and even more so when we combine both of them."
Yoruichi nodded and didn't speak any further. After Kisuke's arm, Kisuke then started healing the rest of Yoruichi's wound she sustained when she detonated her own technique to use as propellant.
Once they're done, they put on new sets of cloaks and exited the Dungeon and returned to their base of operations. Since it's still early in the afternoon, nobody is in the underground base. Hestia is manning the still deserted shop while the rest are exploring the dungeon.
The first thing that Kisuke did is to go to his laboratory to create a specialized drug that could help his arm while Yoruichi returned to their room to rest and recover her expended energy.
It's late in the afternoon when others returned and noticed that Yoruichi and Kisuke got home too. And since Kisuke still hasn't come out of his laboratory, they started pestering Yoruichi.
"Yoruichi-kun, why didn't you even tell me that you guys already returned? I'm just outside, rolling on the shop's tatami floor!" Hestia immediately protested.
"Well, we don't want to disturb you rolling around happily so we just walk pass by..." Yoruichi replied while scratching her face.
"Disturb me! Disturb me because I'm bored that I can do nothing else than roll around!" Hestia wanted to cry at her answer. She didn't want to enjoy rolling.
"Hestia-sama, calm down. Yoruichi-san is just messing with you." Sona comforted Hestia. Due to her stature, natural endowment and cheerful nature, she's reminding her of her beloved sister, Serafall.
While Sona is comforting Hestia, Aika approached Yoruichi and asked, "Where is Kisuke? Did he went straight to his research again after coming back?"
Yoruichi nodded and answered, "Yep. But his goal this time is creating medicine for his wound."
After hearing that, everyone's face suddenly took a turn for the worst, "What, nya!? He's wounded!?"
"Is Kisuke-senpai alright!?"
"Just what did you fight for him to be wounded!? Even if he's partially weakened, he still someone who played around with a Cadre level Fallen Angel!" Sona also stopped comforting Hestia and asked in a hurry.
"How long has master been in there?"
"What about you? If he's wounded, then chances are, you're too..." Aika looked around Yoruichi's body to spot her wounds.
Yoruichi raised her hands to stop their question, "We're fine. We just really didn't expect that the Dungeon can spawn something like that. And you know Kisuke, he probably got sidetracked while doing his study, but he should come out soon."
The girls sighed in relief but they still couldn't calm down without seeing the man himself, so they sat down to wait for him to come out while Medusa started preparing the dinner.
However, one of them didn't want to end it this way and asked, "...Answer me, Yoruichi-kun... Just which floor did you go?" Hestia didn't really want to know as she has a feeling that she wouldn't like the answer, but she still has to ask and do her duty as the Goddess of their Familia.
Yoruichi let out a big smile and answered, "The 50th floor~. We saw that the Loki Familia is having trouble so we gave them some assistance. But in the middle of it, a Monster Rex and Juggernaut spawned so we had to fight more~."
Hestia stood there unmoving and a few seconds later, she slowly covered her face with both of her hands and her back started bending over while she lets out a strange noise, "...Ahhhh... Ahhhh... Ahhhhhh... Strange... Really strange... I didn't hear anything from Hephaestus about two Level 1s going down to the deeper floors on their own and helping out a very strong Familia against monsters... And she said she already told me everything I need to know... That's clearly a lie."
