"Alright. Now, if you want to follow me, you must know that the path ahead is dangerous. The doers of evil will not allow us to easily easily complete our main mission. Hence, we must become sufficiently strong very quickly." With this short Speech, Raiden began training the trio.
For Naruto, he made him focus on chakra control extensively whiles improving his theoratical knowledge. Indifferent Naruto seemed like a totally different person. It seemed his father's genius DNA had finally awakened in him.
Teaching him was now quite easy and in no time, he was done with this phase of training. He the had him train in many miscalleneous and found out ninja paths he actually had talent in medical ninjutsu and fuinjutsu! Of course, as an Uzumaki, he couldn't be bad at fuinjutsu with his brain power unlocked. Also, as the reincarnation of Asura yang nature of chakra was easily manipulated by him.
During Raiden's training over the last month he found out that chakra actually had yin and yang natures. Not affinities, but a quality of chakra - which could be ontrolled.
The yang nature of the chakra prolly originated from the physical essence, and the yin nature also prolly from the spiritual energy.
Naruto's chakra had high yang nature, and the other three had high yin nature. Yang nature was responsible for the vitality & the chakra und Yin for contr control.
As they trained, Raiden secretly aimed to balance the yin and yang in their body or get it closer to the balance to help them draw chakra faster.
'Okay, its time to train in elemental jutsus! really hope to have either lightning, water or wind, elements. The first two because my dad has a lot of resources for them, and the Last one because of the rasenshuriken! that jutsu is outright broken!"
Opening the large scroll, Raiden immediately searched...
~ Two Years Later~
"Lightning style, lightning senbon rain!" A black-and-white haired boy in full black ninja gear with a black headband wrapped around his forehead and two swords strapped behind him shouted as he made a single hand seal to release a jutsu to attack.
'Earth style, Earth wall jutsu!
Shadow clone jutsu!
Combination ninjutsu: Amplified great fireball jutsu!' A figure in black trenchcoat with a pack of arrows strapped behind him responded with his own set of techniques and flickered closer to the other party, slashing sealless wind blades at his opponed hith his clawed gauntlets.The shadow clone shot wind chakra infused arrows from a distance with deadly range and prescision.
The figure in ninja gear also responded with his own set of techniques, flickering and slashing sealless lightning bolts at the incoming wind slashes and attacks.
'Shadow clone jutsu!
Combination Ninjutsu: False darkness waterfall jutsu!' A fast moving waterfall crackling with lightning moved towards the eagle headed figure. The large range covered by the jutsu almost covered the whole improved basement.
'Guess I have to use that jutsu! I've fantasised about this for long! The eagle headed figure thought as a thin film of dark transparent chakra coated his body. Immediately after, he actually levitated off the ground, successfully escaping the attack!!
'Yin release: Chakra manipulation jutsu; Flight!'
This jutsu - Yin release Chakra manipulation - would become the basis of a certain Ninja's exponential growth! The potential of this jutsu was definitely much more than just flight!
The shadow clone shooting arrows on the side also levitated while casting his own jutsu.
' Yin release: Chakra manipulation jutsu: call!' With this jutsu, all the arrows in the room shot towards the shadow clone and into the quiver.
"Its time for the big show! Yin release: Chakra manipulation jutsu; Yin domain! A mass of yin chakra spread quickly in the room. It didn't dissipate into nature however, but stayed in a large radius around him, forming a domain full of yin elemental chakra!
'In this domain, I can maniplilate chakra for attack and defence easier. I can also use a jutsu from any part of this domain!! Anyone caught in my domain would be very be susceptible to genjutsu, and movement is also very easy! Yin release is so amazing! Genjutsu is just the most basic application! With it, using jutsus sealless or with less seals become easier, controlling, manipulating and shaping chakra also becomes very easy! If I'm able to develop this to a very high level, my unorthodox style would catch anyone off guard!
With this jutsu released, The black and white haired youth finally began suffering to defend. It seems if he didn't bring out a trump card, hell be losing soon.
Chakra arrows shot from all over, random Earth spikes, genjutsu distraction and even fuinjutsu! This domain was extremely relentless!
"Sigh, Yama. I've made you too strong! Even without using much earth release, you're a force to be reckoned with! Saying you're already chuanin level wouldn't be an understatement! But I can't fall too far behind, can I ?'
With this, he also decided to use his trump cards. Lightning release, Rasengan!" A Spiralling ball of chakra flickering with unstable lightning flew out of his hand, ringing with a massive explosion a and causing the barrier enchantment to flicker continuously. Luckily, it was strong enough, else the house might be destroyed.
The two purposes of this jutsu were to first clear yin chakra in the atmosphere and destroy the domain, and second, to create an environment rich in Lightning nature chakra for his next jutsu;
'Raiton, Lightning domain jutsu!'
Nearly the whole basement was crackling will deadly lightning as the lightning bolts constantly attacked the figare called Yama. Giving him a hard time in the air!
This was a domain formed from the lightning chakra! It was most intense around him, creating something like a lightning field. Using yin release chakra internally, his sensitivity to chakra increased greatly, allowing him to seallessly use a lot of jutsus and also to easily control the lightning domain!
Of course, this concept of domain was heavily influenced by a certain anime he watched in his previous life...
Back to present, suddenly, Yama had turned around and blocked two swords with his claws! Although he was in the domain, he maintained a small domain of Yin to prevent the lightning chakra from getting too close to him.
He quickly used a rotating wind sphere justu with the chakra from the yin domain to push the figure away.
Damn it! Even with the teleport-like feature of the lightning domain, I still can't catch him off guard! The chakra sensing ability of the yin element is too high! If not for my high yang affinity and experience with genjutsu techniques, would have been defeated long ago. Well, time for the final trump card! I hope this does it."
While he was using the hand seals, Yama 'exploded' out yin nature chakra, creating his yin domain which cancelled out the lightning domain.
'Yin release- Chakra manipulation technique: Absorb!'
The residual chakras left by Yama's jutsus which hadn't dissipated yet were absorbed back into him! Although some at the chakra had already dissipated into nature, most of it was still available in the room.
This was one the broken jutsu's created by Yama! Though it couldn't absorb other People's chakras like dark release or rinnegan, it was still broken enough! This way, staying in battle for much longer periods was still possible!
"Eight tailed demon wolf technique! First tail, Arise!!"
A black and white furred Wolf, thrice the youth's current size appeared in in the dark basement, giving off a huge sense et oppression!
This jutsu I was created by merging two techniques! Eight inner gates and the self created Yang transformation jutsu! The yang transformation allowed one to use yang chakra to transform into with a larger object easier and/or with more solidity and strength. This knowledge was applied to create stronger and longer lasting clones, so that they are not popped easily. The percentage chakra retured to the user also increase from 10% to 20%.With Yin release, Chakra manipulation, almost 100% of the chakra can be retained.
Filling the body with yang provides chakra also some sort of sealless healing ability which depends on level yang manipulation and affinity. With this knowledge, all the excess chakra from opening the eight gates went into creating a small yang domain and revitalizing the body, not burdening at all, but rather, even soothing! The only problem was not being able to open more gates yet due to low physical strength.
With the help of yang release, the physical threshold of opening the gates had decreased a lot! Also, with the help of yin release, opening the gates was much smoother and even controllable with respect to the amount of chakra released! It was now like a tap, a greatly enhanced form of the eight gates technique, now named; Yin and yang release: Eight inner gates technique!
With this technique, his strength had risen by another notch! Theoretically speaking, he could open the gate of death without dying if he trained his physicality to a very high level! Tempering himself in the lightning domain regularly, his strength had already risen physically way above his age, and he even looked to be ten years old now.
Since the opening of the first gate actually allows one to use 100% of one's brain, he became even much smarter in this state! With this new jutsu, he could steadily become the strongest in the world and implement his dream!
