Born as a Sage in Naruto World

When Jun when back to the outskirts of the training ground where he had left the others to practice, he saw everyone lying down on the ground with their hands twitching spontaneously. He realized that they probably had pushed their limits hard.

"What a bunch of idiots. How will they pay attention to the next part of training if they can't even control their body to push their limits without over exerting themselves? Very well let me do something in their stead. Maybe the new jutsus I learnt can help."

Jun turned his nature sensing technique to maximum for accurate judgement of fatigue of their body before drawing in nature energy into him for using a large scale jutsu.

"Well this is the first time for me but here goes nothing. Rat-Horse-Ram-Dog-Rabbit-Ram-Boar-Dog, Nature Style: Wide Healing Jutsu!" Jun's Jutsu healed their damage in the over strained muscles. "Now for their stamina; Rat-Horse-Ram-Tiger-Dog, Nature Style: Mass Relaxation Jutsu" Under his observation, he could see their bodies recover their energy and stamina slowly but steadily. Aside from that he also noticed that Naruto was recovering more than twice as fast as others.

'This is not just me, if let alone he would have recovered within ten to fifteen minutes by himself. Such a sturdy physique and regeneration speed. Such physique should have phenomenal amounts of chakra, even far exceeding what I myself have currently. But then why do I feel his chakra just barely exceeding mine. Is his body using that chakra elsewhere or a defect in his body?' Thinking as such Jun decided to check it. He used his newly learnt Sensing Hexagram Seal on himself to boost his sensing abilities even more. With his one hand boosting the energy in the seal with Nature Energy, He pressed his other palm onto Naruto's chest sending trickles of nature energy coursing into his body to investigate. As the energy threads reached near his stomach, an unexpected reaction took place. The threads got sucked off into Naruto's navel area, revealing a peculiar seal with eight directional sign seals and an Uzumaki in the middle.

'The Eight Trigram Seal! That's the second most powerful sealing jutsu I have till now come in contact with. What the heck is there that needs such a powerful seal? Wait a minute … what... This…' the next moment Jun felt his surroundings go black.

'So it happened finally' old man sitting in a tree 'I wonder how long will he survive without my help and will he figure out the secret of that 'space'. I hope he does, it will definitely help for what he will be responsible for in future.'

Jun finally opened his eyes after a long time and saw darkness surrounding him. He felt as if he was walking in space, infinite blankness all around him. At that point he received an announcement.

[You have entered a Mindscape Dungeon. To escape from this dungeon either defeat the master of this dungeon, or gain his approval, or wait for him to throw you out of his own will. However, although your body is just a copy made from the real body, any damages suffered here will result in a percentage of damage to the real body. Death here can create a severe impact on your psyche at least, even resulting in you going into coma in worst scenario.]

'Wait, a Dungeon? What is that?'

[Sufficient authority required for full access. Full access denied. Basic information available.

'A superior force?' as Jun was wondering who it might be, the scene around him finally became substantial. When he looked around he saw a devastated landscape, barren for miles. Enormous pits and other signs of large scale destruction could be seen in the landscape. However one thing that was peculiar was a giant hill that was seen between all this destruction. Jun walked towards the hill in case he might gain some information about what was happening around him. As he drew closer he was surprised to hear deep vibrating noises from the hill. The next moment the hill itself shook and suddenly started growing. A few moments realized that it was not growing, it was getting up. This hill was in reality a creature that turned out to be many times larger than anything he had ever seen. Finally after many tens of meters, the hill stopped growing and turned towards him. Its form turned clearer slowly, and Jun could see what that hill like creature turned out to be, a gigantic fox which was tilting its head and looking at Jun with its big red eyes. As its eyes focused on Jun's body and aura, it gave a snort and nine enormous tails released from behind its back waving in the air. With that its visage became complete, gigantic orangish-dust colored fox with big twitching ears and nine humungous tails behind it, each thrice the size of the fox itself. The very aura it gave of distorted the air, blasting Jun's face with warm breeze. Each movement of its tails created wind gusts. Jun could easily imagine the mass and strength it must have had to achieve that. Tiny ant like Jun and the mountain like humungous fox faced each other. No movement took place apart from the tails of the fox which swung around at their own pace. Finally the fox reacted, raising one of its huge clawed finger and drew a big circle around Jun.

"Tell me little human, is pepper better or salt?" Fox

"Umm.. Excuse me, I don't quite get what you mean?" Jun

"Well, you dared to come before me. I thought it was obvious that you had come to offer yourself as a meal. It's been so long since I devoured anyone so I don't want to do it raw. You humans have good culinary practices don't you, so you suggest which will be better. Pepper or Salt?" The Fox replied as if it was a very normal thing for him while Jun worked his mind on overdrive on a way to escape this place.
