Born as a Sage in Naruto World

"What the heck is that?" Itachi asked on seeing the round glowing reddish orange crystal in Jun's hand. He could feel the same energy as before emanating from it , only it was not fear inducing one anymore.

"Some thing very potent and dangerous. But also something we cant allow to stay here." Saying so Jun put it into his inventory .

Leaving the dungeon finally , they saw that it was late evening now. Jun sweated bullets when he remembered that Yoshino had prepared dinner for him and he was late. Letting out a sigh of depression he and Itachi parted ways to rush to their respective home.

---------------------------------------

Next day on his way to Hokage's office, Jun was dragging his steps with difficulty. He was mentally tired at the scolding of Yoshino which went on for an hour and was pissed off at Shikamaru and Shikaku who were snickering in the corner, happy that for once it wasn't them that Yoshino was chewing out and instead the victim was 'Perfect Boy' Jun. Jun smiled at the fact that in the end they too were found out and were given a long lecture by Yoshino along with Jun. But deep down Jun was really glad to have a family that cared for him.

On reaching Hokage's office Jun was allowed entry at once. Hokage was surprised seeing Jun so soon but soon recovered.

"What can I do for you Jun?" Third asked

Jun silently took out the Nine Tail Chakra Crystal and held it out to The Third who looked at it with wide eyes "This is ?!!"

"Yes, it contains nine tail chakra" Jun affirmed

"How did you get something like this Jun kun?" Third asked , little bit of seriousness reflecting in his voice.

"When I went to the training ground that seals chakra mutated beasts to train along with Itachi along with many aggressive Mutated Chakra Beasts, I found a Boss Type beast that ruled over them that was affected with this chakra. After defeating it I managed to seal that chakra into this crystal. According to what I suspect the other similar training grounds that hold such beasts might also be contaminated by this type of chakra and may lead to many deaths if entry was allowed in them."

"True. What do you propose then?" Third asked.

"Simple. Since I am the one that sealed this chakra into a crystal that means I can due it for other training grounds too. I just need time to grow stronger. Once I have sufficient strength to challenge a training ground I will do it since each training ground appears to be categorized by their levels of difficulty. So other than me and those I take with me, please seal off the training grounds for others."

"Alright fine. As soon as you are back from the current mission, you will be assigned to this one exclusively. Until you solve this problem no other mission or assignment will be provided to you."

Jun nodded at Hokage's Decision, "Then I will take my leave. I have one day less to prepare before I leave for recovering rest of sealing mirrors."

With Hokage's approval Jun left the office, he had a lot planned for today.

-----------------------------------

Jun went to Nazuna's shop after buying a lot of Fuinjutsu training materials like Barrier Paper, Chakra Paper, Explosion Paper etc. Along with a lot of ink brushes and a lot of food pills and chakra recovery medicine. Also he bought as much chakra metal he could along with iron and steel ingots from the special supplies assigned to ANBU troops, he already had Hokage's clearance to retreive a sizable amount for the mission. On reaching the store he threw the quest item the sleeping shopkeeper had asked to retrieve , his experimental weapon storage scroll. The shopkeeper opened his eyes and came to his senses on seeing the scroll . He raised his headand saw Jun standing there.

"Good Job brat.I didn't think you would accomplish it so soon."

"I had no choice, I am short on time. I will be borrowing the training room downstairs for the rest of the week. And here -" Jun threw another storage scroll at him "- that contains a lot of materials and prototype of my new weapons. I need as many as you can make by the end of this week." Saying so Jun went to the training room and shut the door.

After Jun had gone, the old man unsealed the scroll and took out the materials inside, and his eyes widened as he saw the eight bladed chakra shuriken and the chakra blade inside. He was further astonished on the dense amount of sealing runes on them and he gave a hollow laugh when he realised that he couldn't figure out the meaning of most of the runes.

"Is this a challenge for me brat… Fine .I accept you challenge on my name , Kane, andmy pride as a blacksmith. You will see even better versions of these prototypes. However I am afraid you will have to do the Sealing inscriptions yourself."

Chuckling to himself the old man Kane went to his forging room after shutting the shop and hanging closed sign outside. For a week both of them were completely busy in their tasks . Jun with his sealing art practice and Kane with his blacksmithing.

Jun was taking a leaf out of Naruto's speciality and enhancing his learning speed with shadow clones. He recklessly devoured potions and food pills pushing his body to the limits to gain expertise on Fuinjutsu. Over the week his efforts did pay well.

"Now it should be enough too finally learn that seal." Jun said satisfied with his progress.
