As each scroll was opened, various techniques, either of unparalleled power or ingenious design, were revealed before his eyes.
Whenever there were techniques with novel chakra usage, they always caught his attention.
They brought him unique inspiration, giving him a new understanding of chakra utilization.
As he went through more and more scrolls, he couldn't help but marvel. Chakra, this wondrous energy brought into the ninja world by the Ōtsutsuki clan, truly seemed omnipotent, with usage methods as varied as the imagination could conjure.
For example, the secret technique 'Shadow Stealth Jutsu' in his hand, according to its description, allows the practitioner to blend into shadows, silently assassinating or ambushing the target.
While infiltrating, it would be nearly silent, and attacking preemptively would be difficult to guard against.
This technique could also be used to easily steal intelligence or gather information.
However, the technique had a clear defect: after performing the technique, movement speed would be very slow. If hiding in a person's or animal's shadow, any movement by the target would quickly expose the user.
And if hiding in the shadow of a ninja, it could be easily detected. However, this technique would work quietly during nighttime or when infiltrating the shadows of objects.
It's truly essential for traveling and committing acts of murder and robbery.
Another he had just seen, the 'Water Style Swift Step Jutsu', had given him considerable inspiration for chakra usage.
Before performing the technique, the user would first create a large water-style 'field' using their chakra.
Within the water filled with their own chakra, the speed of this swift step technique is unbelievably fast. It bears some resemblance to the swift step technique used by Haku or Kimimaro in the original work.
Essentially, it allows for high-speed movement within a large chakra-infused 'field', enabling the user to silently approach from behind for a lethal strike.
Or, by using continuous high-speed movement, one could eliminate multiple enemies who entered this 'field' one by one. Its lethality is extremely potent.
However, its drawbacks are also evident, such as massive chakra consumption, especially in waterless areas.
Not every ordinary ninja could create massive water bodies like Kisame Hoshigaki, forming a several-kilometer-wide sphere of water to trap enemies.
Ordinary ninjas using this would suffer huge chakra losses if the target left the water-style field.
It's true that gaining something often means losing something; no wonder ninjas place immense importance on keeping their techniques secret.
There's also the S-rank fire release jutsu, 'Fire Style Flame Dragon Descending', which stood out.
It neutralizes the disadvantage of most fire release jutsus being overcome by water release techniques. By utilizing extreme chakra nature and shape transformations, it creates a gigantic flame dragon dozens or even hundreds of meters long.
This flame dragon can charge into the enemy's water release technique or under the water surface, using its fearsome power to break the enemy's technique or maintain its shape underwater.
Its extreme heat would gradually turn the water into a boiling 'hot spring', forcing enemies hidden underwater out, while dispersing its chakra into the water to prevent enemies from using the water source.
It's highly demanding on chakra nature transformation, shape transformation, and control ability.
All these novel ninjutsu techniques dazzled him and he couldn't keep up.
[Hmm! Traversing miles in an instant is a bit exaggerated! If I could learn the Flying Thunder God, there's still a chance for such instant movement over a hundred miles!]
[I really want to copy all these techniques and take them home for detailed research!]
Whether it's the nature transformations, shape transformations, or ingenious designs of these ninjutsu and secret techniques, they greatly broadened his horizons.
He believed that by fully understanding all these techniques, his comprehension, application, and understanding of chakra would reach a new height.
In his view, all ninjutsu, secret techniques, or even bloodline limits were merely different applications and transformations of chakra.
Once he grasped the fundamental principles, the lofty Kage-level powerhouses would no longer be so unreachable.
[It's a pity that there's no Flying Thunder God or Edo Tensei developed by the Second Hokage Senju Tobirama here!]
[A futile hope, I remembered that Madara knew Edo Tensei in the original work. If there was a collection in the clan, another Flying Thunder God wouldn't be surprising!]
[Otherwise, there would be no need for hesitation, just choose Flying Thunder God Jutsu. Regardless of whether I can successfully learn it, try it first!]
With this hidden regret, Hitsugaya finished going through all the scrolls and walked towards Fugaku, who sat with his back to him at the stone platform.
He had finished going through all the scrolls merely to broaden his horizons and gain inspiration for using techniques and chakra.
Once he confirmed that the secret room did not contain the Flying Thunder God Jutsu, he had already made his choice.
"Senior Fugaku, I apologize for the wait. I have chosen my target!"
At the moment, on the cushion in front of the stone platform, Fugaku, sitting cross-legged, opened his eyes that were seemingly closed in meditation.
"Oh, have you already chosen?" Hearing Hitsugaya's voice, Fugaku turned to look at him and inquired.
"Which ninjutsu or secret technique have you chosen?"
He was curious about what this mentally mature clan junior would ultimately choose.
[Would it be those mighty S-rank ninjutsu?]
[Or those mysterious and unpredictable secret techniques?]
The former might be too powerful for someone of this young age, with high chakra consumption and rigorous requirements for chakra nature and shape transformation.
The latter, with its demanding requirements for talent, wasn't something ordinary ninjas could learn at will.
As for the sealing techniques, barriers, runes, and curses, he didn't consider them; boys at this age wouldn't be interested in those. They often chose techniques they currently couldn't realistically use.
He didn't know that the boy in front of him was very interested in sealing, runes, and curses, but given limited opportunities, he could only choose the most beneficial one.
