"Naruto liste- NARUTO." The future Naruto panicked, shouted in worry. This was because the younger Naruto was on ground breathing heavily with quite a amount of strain on his hind legs and arms.

What's happening? What suddenly happened? Future Naruto thought in worry. He grinded his teeth together. Naruto was doing fine. There wasn't any mental pressure either. Unknown to him, this was something as a boon and bane. The fate of the shinobi world as well as of Naruto was changing this very moment.

"H-huh? What am I doing here?" Younger Naruto asked with faint dizziness. It was like someone suddenly transformed him into a cloth and put him in washing machine. His mouth felt dry. What was happening again?

"Welcome Naruto." Older Naruto said as he stepped out of the shadows. Slowly the darkness in his mindscape decreased and all the tailed beasts came in light. "This happens when your body is tired but your mind doesn't know about it. You are automatically succumbed into your mindscape." He sat down and releasing a sigh. "Alright tell me what happened. From the beginning."

Younger Naruto nodded. "I was doing your exercise when suddenly after I dispelled the clones I felt- um...."

Brat. Kurama cut in between. Take your time. At least we need to know about what happened.

"How do I say it? I suddenly felt like my arms and legs were burning and my muscles were ripping apart. It was like someone was grinding my muscles from inside." Naruto finished his somewhat lame explanation. Looking at his hand he could see that it was red. Bloody red. Like someone stretched apart his tendons and was now bending it cruelly.

Everyone started thinking. What could be the sudden reason? The brain usually knows what our body is doing. The subconscious mind helps in even the beating of heart. How could his muscles suddenly be strained? This was just out of question.

I see. So that's how it is. Lucius said after thinking for a while. I think I got it.

"Lucius?" Older Naruto asked. "What do you mean? What did you understand?"

I think I know the reason for the sudden pain and strain on his muscles. The sudden erratic breathing. Dry throat. It makes perfect sense. His eyes lit up in recognition. He may have the perfect answer. And if his answer was spot on then it could help the younger Naruto in more ways than one. Heck, it could complete the training as well. No. Forget training. It might be a boost. A grand and great boost. Powerful enough to make the younger Naruto that - um what was that again? Pokage. Right. Naruto could be the next Pokage.

"First of all explain it to me." Younger Naruto shouted. "I'm here as well." He pouted closing his eyes. Looking like a cute little fox.

What did you get Lucius? Shukaku asked surprised. No one expected any answer from Lucius. Future Naruto- maybe. Kurama-maybe. But not Lucius. He wasn't even there on Earth. How could he have the answer.

It's a boost. I think I might tell but for now I think we need to test it. Lucius said with a hungry glint in his eyes. Damn Ten-Tails. They were always scary. Alright. Maybe other than Lucius. But it's true. Do anyone of you know any Chakra molding jutsu? Any one you know. Where there is necessity for Shape transformation.
