A/N : Hey Guys, Im back, had some difficulties the past month so wasn't able to actually write, Ill pick up from where I left.
Hiro looked at the spiraling blue ball of chakra in his hands as contemplated what to train ahead.
With practice, he had came to realise that Altough increasing the chakra in the rasengan increases it's damage, increasing the Rotation speed of chakra makes it even more deadlier.
Plus, the latter factor depended totally on one's chakra Control and skill.
The efficiency of his Destruction Wave had already increased by so much due to all the practice, that he could get the same results as he got the first time with just half the chakra.
That meant he could use a Destruction wave without completely draining himself of chakra.
Altough the technique, now that it had been refined, bordered on S rank boundry due to its focused damage, Hiro could feel that it was missing something.
'Is this what 4th hokage felt when he created rasengan? Deeming it an incomplete jutsu? Hmm.....' Hiro thought.
Due to the virtue of his Perks and Abilities gained from Hinata, along with his cheat like gloves, Hiro had mastered the shape transformation of chakra in in just the day before, another thing that helped him through the process was his insane recovery of chakra.
Since the first step had been completed, along with the fact that Hiro did not like making/wasting time on handseals, the next best course of action was mastering the nature transformation of chakra.
Nature transformation was a really Advanced step, only those of mid jonin and above level trained in it.
[A/N : Just for clarification, here, mastering shape transformation is not a necessity before one trains in nature transformation.]
Nature Transformation was an incredibly useful Perk if one increased their proficiency in it.
Normally, to transform chakra into your desired nature, you bring it up to your hands, knead it in the required manner with the use of hand seals to turn it into your nature then add hand seals to shape it off and voila, a Ninjutsu.
Take the infamous water dragon jutsu was example, it has a total of 44 hand seals, more than 30 of them are to knead the chakra into potent water element.
On average, almost 60%-90% of all hand seals in a jutsu are required for nature transformation of chakra through a rigorous kneading process.
As such, if one could increase their Nature transformation of chakra through intense training, they could drastically reduce the number of hand seals required to perform the jutsu.
Mastering both Shape and Nature transformation were key to performing jutsus without hand seals.
Hiro dissolved the rasengan in his hands as he took out a chakra paper, and pushed some chakra into it.
'It's, sill the same' He thought.
The paper, had first gain a few shallow cuts on it, then it crumpled a little and then it started smoking as red glow could be seen on its edges.
When Hiro awakened his chakra, one the first things he did was check his elemental affinity.
It was wind, altough a rare element, his affinity was extremely poor, not even able to cut the chakra paper in half.
And with his 'adventures' with Hinata, he had gained her affinities too, though what he recieved were just as weak as his wind affinity.
Wind, Lightning and Fire.
Hiro possessed the three most destructive natures of chakra.
Altough one would have been ecstatic of they found this out, Hiro knew that due to how low his affinity was with each element, it would be a pain in the ass to train them all.
The reason was simple, the greater ones affinity to an element, easier they could learn to transform their chakra into that Nature.
And even then, it would take them years to learn it.
But, Hiro, had atleast one relief in his mind, that was 'If a moron like Naruto can do it in a couple days with hundreds of clones, I can do it in less than a couple months without the clones'
Altough Hiro knew the Shadow clone thanks to Hinata, But even with his high hopes, he soon came to realise that he cannot use them for training.
They were too mentally taxing for him, and fatigue carried over by them was quite real.
And now with him learning his new breathing technique, he could not afford to be mentally exhausted otherwise it could cause severe backlash if he was caught off guard.
It was better to just use his fast recovery to boost his training speed rather than using shadow clones.
The first nature that Hiro was going train was obviously Wind. He knew how to train it from different manuals and his knowledge of Cannon.
As such, he took ten leaves, controlled each of them to come to the tip of his ten fingers and started training.
This was the benefit of perfect control granted by his glove, altough this required concentration and heavy expenditure of chakra every second to maintain this technique with ten leaves.
In just a few minutes, Hiro felt his chakra pool get halved with the expenditure, with no visible result.
Hiro shook his head as he maintained a serious expression on his face, recovering his chakra using his breathing technique whenever his chakra fell below 20%.
Doing the same thing over and over for 4 hours, Hiro was finally able to induce a small cut, only a millimeter at most though, still it was great progress, with this speed, he will be able to complete the Leaf cutter exercise in a couple weeks.
It was now noon, Hinata was still practicing the 'Air walk', both of them had some lunch as they got back to their respective training again.
This time, Hiro continued for an hour more till he was satisfied with the results he had obtained today in the elemental transformation.
Hiro discarded the leaves that were on his finger tips as he called Hinata over for his breathing practice.
Ever since he had founded / remade the technique, he had been trying to improve his timing over his breathing.
Hiro sat on the tree stump shirtless with his legs crossed as he closed his eyes and felt the air moving into his lungs.
Hinata, who was standing to his back, had her Byakugan activated while her hands were extended, a green glow coming out of them as it went into Hiro's lungs through his back.
Altough Hiro could do the healing of his lungs by himself, it was much faster and much efficient with Hinata doing it for him, plus, it was one less variable he had to worry about.
Soon, his breaths started getting heavy as he started inhaling and exhaling huge amounts of air.
A sudden pressure wave formed around him as his face became red due to the increased bloodflow.
His long hair were waving in the air as if they weren't under gravity.
What he just did was opening the second gate in his body, the [Gate of Healing]
He was using the excess chakra that was being generated each second, to open his second gate gently.
The opening of first two gates was crucial to him, both as a means of gaining strength and maintaining it.
The first two gates removed the mental limiters and physical inhibitors inbuilt by biology to make one able to use their full physical strength and increasing the secretion of stimulating and pain reducing hormones in the body.
Just the use of these two could improve ones strength by 5-8 times.
Hinata continously pumped in the green healing chakra into Hiro's lungs, regenerating and reinforcing them every second.
Under this gradual process of putting his lungs under pressure, damaging and regenerating them in the process, Hiro's capability to use the breathing style had been expanded. By the estimated speed of his lungs' reinforcement process, Hiro had deduced that he could keep the first two gates open for almost an hour before he would have to close them lest he faces some backlash.
Hiro, could feel the immense chakra flowing into his muscles, he could feel them getting stronger by each passing second.
'Maybe this is what they refer by "refining" in those LNs...' Hiro thought.
The heavy flow of chakra was stimulating his muscles in such a way that they were getting more dense by each passing second.
Muscle fibers were slowly readjusting themselves to accommodate the increased flow of chakra.
Those contractile tissues were slowly getting more dense and each cell was absorbing chakra to increase their quality.
This kind of benefit was completely overlooked by Hiro at first, but for the last few sessions that Hiro did with second gate open, he had been seeing gradual increase in his base physical attributes.
About 1-2% in each session.
That was an unexpected, and a huge gain for him, now, he doesn't need to train with bone crushing exercises to see the gains, well he does, but now the time needed on that aspect could be replaced by just breathing practice, saving him a couple more hours each day.
In just 50 such 1 hour sessions, Hiro would be able to increase his physical attributes by more than double.
As one hour came to pass by, Hiro stopped his breathing practice as he turned around to see a sweaty Hinata with her hands shaking a bit.
Using such an intensive technique for an hour nonstop was no small feat, only by the virtue of her increasing chakra control was she able to continue for such long time.
Hiro, grabbed Hinata's shaking palms as he grasped them and gave them a kiss on her knuckles as he mouthed to her 'Thank You' with a smile.
A/N : More stones.
For those who are having trouble understanding his breathing technique, I'll elaborate it more.
The huge amount of oxygen intake from his lungs stimulate his chakra coils to generate huge amounts of chakra.
This chakra just fill up the chakra pool and then escapes to the chakra pathway system where if it is not used in ninjutsu, it will escape through hundreds of tenketsu over his body passively.
Usually, muscles only get small amount of Chakra, but by the virtue of Opening the gates, heavy flow of chakra into the mind and muscles becomes possible.
Hence, it increases the physical attributes by immense degrees more and more as one opens more gates.
Hope that clears it, if you guys do not understand why some things are happening or how things are working, just ask, I will try to explain it like this, some things I want to add into the story but refrain as it just feels like an info dump.
