Swish swish swish~
Afterimages flew by, yet there was no sound of breaking wind that usually accompanied a physical body moving at high speed.
It seemed that within the Kekkei Genkai space formed by the ice mirrors, rules existed that were different from the outside world.
After a while, Musashi felt his highly concentrated mind becoming fatigued, so he called a halt to Haku, who was consuming a massive amount of chakra.
"Alright, Haku, stop for now."
Without waiting for Haku to dispel the Kekkei Genkai, Musashi rushed to the table and spread out pen and paper.
Analysis on the Characteristics of the Kekkei Genkai—Crystal Ice Mirrors
Summary of Ninjutsu Characteristics within the Space Formed by Kekkei Genkai Secret Techniques
On Elementalization—Conjectures on the Degree of Chakra Nature Mastery and the Possibility of Elementalization
One topic after another was recorded by his hand. Gradually, stacks of notes began to pile up.
A long time later, Musashi stopped writing, and Haku had recovered some of his chakra.
"Haku, let's continue."
"No need to use Crystal Ice Mirrors this time."
"Just slowly condense the Ice element."
The completion level of Crystal Ice Mirrors was too high, and the principles behind the technique were too complex for him to figure out in a short time.
Start with the simplest part first.
Understanding the synthesis of the basic 'Ice Style' and figuring out the principles behind it was the topic he valued most and found most difficult at the moment, aside from his research on 'Taijutsu,' 'Sealing Jutsu,' 'Lightning Style Activation,' and several chakra nature transformations.
Sharingans, Shikotsumyaku (Dead Bone Pulse), Byakugan... these Kekkei Genkai relied too heavily on bloodline and weren't suitable subjects for his research.
Compared to those, Kekkei Genkai like Ice Style, Lava Style, and Boil Style had clearer attribute conditions for synthesis, making the possibility of achieving results greater.
After all, even Particle Style could be learned and passed down; there was no reason why other elemental Kekkei Genkai couldn't be researched.
Ancestors mastered powers through cultivation, which then integrated into their bloodlines over generations to become Kekkei Genkai. Now, Musashi wanted to reverse the process and grope for the principles from existing Kekkei Genkai.
Even if the probability was very low, he had to try.
This was the instinct left over from years of being a scientific research drone.
Haku extended his hand.
Chakra emerged bit by bit.
Once it left the body, it manifested the properties of ice.
Musashi wrapped his palm in chakra and touched the other's chakra deeply, feeling the formation of ice.
Unlike the ice mirrors, in the slowly condensing block of ice, the chakra carried a subtle corrosive property, seemingly wanting to turn the chakra on Musashi's hand into icicles along with it.
Ignoring the slight stinging sensation from his hand, Musashi closed his eyes.
Abandoning visual observation, he experienced it carefully.
It was known that the 'Ice' attribute was a combination of Wind and Water attributes.
So, what was the proportion of the Wind attribute? How much did the Water attribute occupy? This was the question he needed to understand most.
Besides that, what level of chakra was required to meet the conditions for synthesizing the Kekkei Genkai?
Ten minutes later, Musashi withdrew his hand again.
"Haku, besides your Kekkei Genkai, have you mastered ninjutsu of other natures?"
"No." Haku shook his head.
"After awakening my Kekkei Genkai, I met Mr. Zabuza before I had the chance to learn other ninjutsu."
"He told me that my Kekkei Genkai is a precious ability superior to ordinary ninjutsu. I just needed to bring out the power of the Kekkei Genkai properly."
"Is that so..." Musashi mused slightly, then walked to the side and dug out two ninjutsu scrolls.
Handing the scrolls to Haku, he said, "Try attempting these two ninjutsu. I want to see the effect."
"They are both basic ninjutsu. With your strength, you should be able to master them very quickly."
Haku accepted them with some surprise.
Wind Style: Great Breakthrough (or Wind Style: Air Bullets/Gale Palm depending on translation of Wind Blow Cut), Water Style: Wild Water Wave.
Two basic C-rank ninjutsu.
"Senior Musashi, right now?"
"Yes! Right now," Musashi affirmed.
Haku had no choice but to start reading the ninjutsu scrolls.
From the principle of the technique to the order of hand seals, the scrolls were filled with notes made by Musashi, very comprehensive.
Five minutes later, Haku put down the scrolls.
"I'll give it a try." Saying that, his hands began to form seals according to the formula recorded in the scroll, and chakra began to condense.
The temperature in the room began to drop again.
Musashi frowned slightly. "Haku, control it. Don't condense Ice attribute chakra like you usually do."
"I'll try my best."
Haku began to attempt it again.
Once, twice... ten minutes later, as Haku finished forming seals once more, the chakra successfully began to activate according to the requirements of the jutsu.
"Don't be afraid. The room has a barrier. Go ahead and unleash it boldly."
Hearing Musashi's words, Haku no longer hesitated.
"Wind Style: Wind Cutter!" (Assuming Wind Blow Cut translates to a cutting wind jutsu contextually)
Inside the quiet room, the wind rose abruptly.
Sharp wind blades condensed into form, then whistled as they flew forward.
Suddenly, Haku cried out in alarm.
He saw Musashi suddenly step forward the moment the Wind Style ninjutsu formed.
A thin layer of lightning covered his hand, and he actually touched the wind blade with his bare hand.
Clang clang clang!!!~ Several crisp sounds rang out.
In Haku's panicked gaze, Musashi was fine.
The thin layer of Lightning Style chakra on his hand was partially destroyed by the wind blade.
A few blades, under his deliberate control, broke through the Lightning Style chakra and left a few shallow cuts on his hand.
Looking at the cuts on his hand, however, Musashi's eyes were very bright.
