Two days had passed since Kurama had decided to take a short break and was just waking up from his lethargy.
"I have to admit that I was exhausted..." - murmured Kurama as he began to stretch.
"It's good to see you've woken up! - exclaimed Fukasaku as he entered the redhead's improvised room - "I've been coming to your room every two hours to see if you'd woken up during the last day!"
"What's going on?" - asked Kurama with a scowl as he saw the old toad's reaction.
"Akatsuki! - Fukasaku exclaimed as he looked at the boy - "They have been attacking Kumo for more than three days!
"!" - Kurama opened his eyes when he heard this while making a hand seal.
"Huh?" - A clone appeared in front of him and from the expression on his face, it was obvious that he didn't know what was going on - "Boss?
"Tell me what's been going on..." - said Kurama with a scowl.
"I don't know... I'm still on Oni no Kuni... - replied the clone as he scratched his cheek - "Actually, I have a little problem, Boss..."
"Is it lethal?" - asked Kurama while he squinted.
"No... it is more accurate to say that it is... awkward..." - replied the clone with a forced smile.
"We can solve it later," snorted the original Kurama.
"No... but my side is not free of problems" - answered the clone - "The truth is that..."
But before I could say anything else, he disappeared as quickly as he appeared.
"That didn't help me at all..." - murmured Kurama as he frowned - "Anything important I need to know?"
"According to what Jiraiya-chan said when he invoked us to help him, Kushina contacted him saying that they would use the 'Special Room'," responded Shima with confusion.
"Oh? Did she succeed?" - Kurama asked himself as a smile appeared on his face - "That's something interesting..."
"What is interesting?" - Fukasaku asked in annoyance.
"First I want to see how Tsunade-chan is doing," answered Kurama as the three of them walked in the direction of the blonde.

"This is getting out of control..." - murmured Matatabi through her connection to Yugito as she grunted irritably - "Even at this distance, I can feel Gyuki fighting with everything he has..."
The girls had received the report of Akatsuki's attack but after discussing it with A, Kakashi, and B, they decided that Yugito would not go to Kumo even if it fell because it was obvious that Akatsuki was looking for the time to get two Bijuus for the price of one.
"I know... but B sensei made it very clear that he didn't want us at Kumo..." - Yugito answered with regret.
"Even that idiot Gyuki doesn't want me around... I guess the situation is much worse than we thought..." - sighed Matatabi - "At times like this, I wish Kura-nya was with us... he always knew what to do despite how much he found others annoying..."
". . ." - Yugito was silent as she listened as she sighed with regret as she discovered how dependent they were on Kurama. He had only been gone for two months and things had already gone to shit, to the point that they wished he was here to solve everything.
"Kushina-chan..." - Mikoto said seriously - "Is the situation in Kumo that bad?"
". . ." - Kushina was silent when she heard this question because, being the only one who had gone to the Hidden Village in the Clouds, she could be sure that chaos was present, even on the first day of the 'War' against Akatsuki.
"Your silence does not calm me, Kushina-san..." - said Mabui while looking at the redhead - "Please tell me how things are in my village..."
"Bad..." - responded Kushina while she let out a sigh - "Akatsuki sent all his remaining members and Kumo is doing everything possible to stop them along with the help of the other villages..."
". . ." - the girls were silent when they heard this as they looked at each other helplessly.
"I'm sorry but I need to go back," Samui said seriously. "I know my help won't be enough but I can't let Kumo fall while I'm safe"
"I am going with you" - answered Mabui seriously - "I may not be A-sama's secretary anymore but I still consider him a good friend..."
"I..." - said Yugito as she stood up, only to be interrupted by her companions.
"I'm sorry Yugito but you will stay" - said Mabui firmly while Samui nodded - "You are their target..."
". . ." - Yugito bit her lip when she heard this as she shook her head - "No... if they want me, then they will have me"
"If they're so determined, I guess I'll have to use that..." - said Kushina as she looked around.
"What?" - they all asked with surprise and curiosity.
Kushina did not answer, she quickly created a clone and sent it to Jiraiya to inform him that they would not be available in a while, she also created another one to tell Sakura to take care of the children for a few days before looking at the other girls - "Follow me..."
The others looked at each other before nodding and following the redhead until they reached a wall. Kushina put her hand on it and quickly the wall began to disappear, revealing a ladder.
"Ok, I didn't expect that..." - said Anko with surprise.
"You'll know soon enough" - replied Kushina as she walked down the stairs.
The girls quickly followed the matriarch Uzumaki, only to be surprised by what they saw.
They had arrived at a beautiful corridor that seemed to be natural. The walls were made of solid rock, only they had fluorescent stones of all colors, and in the process, giving the corridor a mystical look.
"What kind of stones are those?" - Ino asked curiously.
"I don't think that's important right now," answered Hinata as she shook her head.
"I agree with the Masochist" - Anko nodded as they watched Kushina arrive at what appeared to be a huge door of about ten feet - "Okay? Does anyone else feel that we are about to enter some kind of sanctuary where human sacrifices are made?"
"Kushina..." - said Tsume as she looked at her friend.
"Don't worry, I'm about to explain what's behind this door," said Kushina as she looked at the girls.
"Just say it, Kushina-chan" - said Mikoto as she rolled her eyes.
"That's what I'm going for..." - snorted Kushina as she shook her head - "Anyway, this is the last project I've been working on... the name of the project is Project Z: The Hyperbolic Time Chamber... or at least that's what Kuro-chan called it after I told him about my idea"
"The Hyperbolic Time Chamber?" - whispered the girls curiously as they heard the name.
"Exactly, it consists of the creation of a special room fortified with different types of Fuinjutsu to increase the level of training" - continued Kushina while looking around - "Inside this room, time passes differently from our current time, a day outside is a year inside, and not only that, there will also be a constant increase in gravity until reaching 50 times the gravity of the Elemental Nations, although this limit can be expanded with other gravity seals...".
"!" - The girls opened their eyes in surprise when they heard this while Mabui and the other Kumo girls felt their breaths stop for a few seconds because of such a miraculous location.
"One more thing, this room has been reinforced not only with Barrier seals but also with Kuro-chan's Mokuton, making the walls almost unbreakable in the process" - continued Kushina with a proud expression on her face, although her expression changed to a serious one when she noticed how happy the girls were - "Although things are not as perfect as you think, After all, time continues to run inside naturally, that is, we will lose a year while time runs outside the room, it is even possible that our vitality will be damaged if we spend too much time inside The Hyperbolic Time Chamber. …"
"What is the limit?" - Mikoto asked with concern.
"I would say two years at the most," Kushina replied seriously, "They can be continued but that's the limit with no exceptions because if we stay longer, our internal clock will be affected, and in the process, causing the life span of our cells to become shorter and shorter...".
A deep silence invaded the place but the girls' expressions did not change.
"Two years is more than enough" - said Anko firmly while the others nodded.
"Then I think it's time we let our friends that we will be busy" - said Kushina as she nodded firmly.
"Shall we tell them about The Hyperbolic Time Chamber?" - asked Ino as she tilted her head.
"There is no need to hide anything about the [The Hyperbolic Time Chamber]," answered Kushina with a smile.
"Ok" - the girls nodded as they created clones and sent them home - "I guess it's time for us to show Akatsuki that the Uzumaki clan is not only strong thanks to Kuro-chan..."
