9 months later.
naruto was alone in the training ground with a serious look on his face seemingly in deep thoughts after thinking he ask system.
naruto: system is my body strong enough to bear the burden of the first impulse.
[yes.. host current body can barely take the burden of 1st impulse but the host will still need to be careful]
hearing this Naruto nodded with a serious look.
naruto took the horse stance and starts concentrating his mind on the fusion.
the muscle in his body starts to become erect, veins bulge out from his forehead and his body starts to emit an invisible overwhelming momentum.
inside Naruto's body,
he concentrates his 2% chakra and 2% soul energy and start fusing them, just as these two forces come in contact with each other, a loud explosion occur in Naruto's body and a large amount black colour energy was produced, this energy starts to channel itself towards naruto's chakra points.
as this energy come in contact with the chakra points, it forcefully opens them, it continued until all the chakra points inside Naruto's body were opened.
while this was happening inside Naruto's body his outer appearance starts to change as well, his hairs started to turn black and a light black lustre appears on his skin.
an intense black energy burst out from his body turning his surrounding chaotic.
naruto's body was still under great pressure but he could still hold it, he looked at the changes in his body and shocked look appear in his eyes after a moment he forcefully calm himself down and decided to test his power.
he made a fist and smash it directly in the ground, as the fist and ground come in contact with each other.
bbbbboooooommmmmm!!!!
a loud explosion occur and a giant crator was formed almost destroying the entire training field.
naruto: holy hell, the power of 1st impulse is almost equal to that of the 3rd gate shown by lee at the time of chunin exam.
naruto: system how long can I maintain this form.
[by host's current strength host can atmost maintain this form for around one minute with light muscle injuries.]
naruto: one minute huh, this should be enough,
after testing his power he decided to check his speed.
he pushed the ground and his body vanished from his original position and appear on the other side of the training field and just as he was about to further test the limits of his body he felt a strange feeling inside his body and just as he was about to check what it was, a huge amount of black colour blood come out from his mouth and he lost his consciousness.
after loosing consciousness, his body changed back to its previous self.
.......
Konoha's hospital.
naruto slowly opens his eyes, after looking around he found himself in the hospital.
he was confused about what happened when he felt that strange feeling inside of him so he ask system.
naruto: system, why did I loose my consciousness.
[when host fused his chakra and soul energy the newly formed energy spread throughout host's body and start removing impurities in the form of black blood and when this energy come in contact with host's chakra points it forcefully opened them, resulting in putting too much pressure on host body and due to this host lost his consciousness.]
naruto: system, will it happen everytime I activate impulse.
[no this a one-time phenomenon, since host body has been cleansed, the energy will be able to more freely]
hearing this naruto nodded and ask system.
naruto: system show me my current status.
[showing]
....
name: naruto uzumaki
age: 11 years 11 months
energy level: 1462/10000
power level: low-class chunin.
chakra type: wind(active), lightning(inactive), space (sealed)
...
reading his energy level naruto was shocked.
naruto: system why did my energy level increased so much.
[after purification process, host ability to wield chakra also increased exponentially]
naruto: that is a good thing then.
just as Naruto was thinking six figures enter his room.
seeing them naruto was shocked because the third Hokage and hiashi Hyuga (Hinata's father ) were among them. apart from them, there were Hinata, Lee and Iruka.
hinata and Lee had a worried look on their faces.
sarutobi and hiashi had serious look on their faces.
and Iruka was looking at naruto with an angry look.
seeing that Naruto has woken up, Iruka approached Naruto and hold his ear.
naruto: aaaahhh sensei what are you doing.
iruka: what I am doing huh, what were you doing naruto that caused you to be hurt this badly.
hinata: sensei naruto is injured you should not be too hard on him.
hearing this Iruka let go of naruto's ear and a worried look appear on his face.
sarutobi: Naruto would you mind telling what were you doing which results in you being injured.
hearing this Naruto thought for a while, he knew that he could not tell sarutobi about 'inner chakra impulse' so he made up a story in his head and said.
naruto: I was trying to break the limits of my body and while doing that a violent energy suddenly burst out of my body which I was not able to contain and ended up injuring myself.
hearing this a frown appear on sarutobi's face.
sarutobi: what sort of energy was it.
naruto: i only know that its colour was orange and I could feel deep killing intent from it.
hearing this a figure appear in sarutobi, hiashi and iruka's mind and their body unconsciously shudder.
sarutobi did not ask further since he could guess that it was Kyuubi.
he collected himself and said to hiashi Hyuga in a low voice.
sarutobi: hiashi, check whether his body is damaged anywhere.
hiashi nodded and activated his byakugan, the nerves around hiashi's eyes bulge out and serious look appear on his face.
as he was checking a shocked expression appear on his face, seeing his expression a worried look appear on sarutobi's and iruka's face.
sarutobi: is his condition serious
hiashi came out from his dazed state and said.
hiashi: apart from some damaged muscles his body is completely fine, but..
sarutobi: but what..
hiashi: for some reason all of his chakra points are open.
sarutobi: what, how is this possible.
seeing Hokage's expression Hinata ask with a worried face.
Hinata: Hokage-sama did something happen to Naruto.
hearing this sarutobi regained his calmness and said with a smile
sarutobi: no he is completely fine, he just need some rest.
hearing this Hinata relaxed.
after this, the three adults left the kids alone and went out to discuss something.
....
after sometime Iruka came in said to Naruto in a strict tone.
iruka: naruto from tomorrow onwards you will have to attend the academy.
hearing this Naruto nodded since he already accomplished what he wanted, he does not mind going back to the academy.
naruto: yes, iruka sensei.
after hearing this iruka left and naruto ask hinata and lee.
naruto: so, what are you guys doing here.
