Yin Release

Waking up, I discovered the world outside had turned into a vast expanse of white.

It had snowed!

I opened the window to take in a breath of cold air and surveyed the snowy scene before finally getting dressed, washing up, and heading to the study to look for the Yin Release scroll.

"What are you looking for? Do you need my help?"

My father, Yu Fenglan, appeared at the doorway. He was wearing pajamas, his hair was a mess, and he sported a beard; his appearance could only be described as above average.

Clearly, Genma had inherited his good looks from his mother.

Provided he didn't grow up to look crooked later on.

"I'm looking for the Yin Release genjutsu scroll."

Genma turned around and said.

Yu Fenglan scratched his head and stepped forward: "Yin Release?"

"Son, aren't you supposed to be learning medical ninjutsu from your mother?"

"You're still young; you should focus on mastering one type of ninjutsu first. Even if you are a genius, you shouldn't be too ambitious!"

Despite saying this, Yu Fenglan still quickly found a genjutsu scroll.

Genma reached out to take it, feeling quite speechless: "My dear Lord Yu Fenglan, is it possible that I have already finished learning medical ninjutsu?"

"Huh?"

Yu Fenglan scratched his head in embarrassment: "Is that so?"

"As expected of someone who inherited my wisdom, hahaha~"

Genma rolled his eyes internally.

If I inherited your wisdom, I'd never be able to make a living as Hokage in this lifetime.

However, this wasn't out of disrespect for the man who raised him; it was simply because he had the soul of an adult inside this body, so he and Yu Fenglan interacted more like buddies.

Patting his son on the shoulder, Yu Fenglan said: "You take a look first. I'll go wash up and come back to teach you."

With that, he turned and walked out.

Genma didn't mind, sitting directly on the carpeted floor and opening the scroll to read it quickly.

The scroll was clearly written by Yu Fenglan himself; Genma recognized the handwriting.

The beginning contained content regarding the nature transformation training of Yin Release, while the latter part detailed specific techniques.

It started with three genjutsu, followed by a sensory ninjutsu.

Genma scanned through everything first before returning to the beginning for a careful, in-depth read.

The Ninja Academy taught basic knowledge like chakra nature transformation.

But it did not include specific training methods.

Therefore, while Genma knew the definition of Yin Release, he wasn't clear on the specific training methods.

Of course, having already mastered Yang Release nature transformation and possessing a wealth of information, he had certain hypotheses about Yin Release nature transformation.

Now, seeing the training notes left by his father, some of those theories were confirmed.

So-called Yin Release nature transformation is the creation of form from nothingness.

The corresponding Yang Release, or rather, Yang Release nature transformation, is the act of bestowing life upon that form.

That is why the Sage of Six Paths used the technique of Yin-Yang Release to create the nine Tailed Beasts based on the Ten-Tails' chakra.

Of course, that was far too lofty a concept.

There were many clans in Konoha famous for their Yin Release nature transformation.

For example, the genjutsu of the Kurama Clan, the Mind Transfer series of secret techniques from the Yamanaka Clan, and the shadow secret techniques of the Nara Clan.

Using the shadow secret techniques to verify the definition of Yin Release made it much easier to understand.

An object's shadow is originally intangible, but through Yin Release nature transformation, the shadow is granted the ability to materialize, allowing one to control the main body through the shadow or use the shadow to kill.

"One of the manifestations of Yin Release nature transformation is turning the intangible into the tangible, such as the shadow secret techniques."

"Then, as for genjutsu..."

A wealth of knowledge flowed through Genma's mind.

Genjutsu has many classifications; it can be subdivided into visual-type genjutsu, auditory-type genjutsu, tactile-type genjutsu, and so on, categorized by the five human senses.

Of course, there are also those that affect multiple or even all senses simultaneously.

"How is it? Any questions?"

Yu Fenglan's voice interrupted Genma's train of thought.

Sitting down on his backside opposite his son, Yu Fenglan said: "Actually, Yin Release is harder to learn than Water Release."

Genma spoke the truth: "It's alright. I don't feel like it's that difficult to understand."

"I know quite a few people in the village who use Yin Release nature transformation, such as the shadow secret techniques of the Nara Clan, the secret techniques of the Yamanaka Clan, and the genjutsu of the Kurama Clan."

Yu Fenglan was not surprised; he had long since grown accustomed to his son's maturity and intelligence.

Furthermore, his son's classmates surely included members of the Nara, Yamanaka, and Kurama Clan.

Genma continued, "I've summarized it: the common thread is that they all interfere with reality."

Yu Fenglan raised an eyebrow slightly upon hearing this, rubbing his chin as he remarked, "An interesting summary."

Genma said, "Yin Release creates form, and Yang Release gives form life; that is far too advanced for us."

"Therefore, mastering the nature transformation of Yin Release must start with the basics. Take genjutsu, for example—to be specific, visual genjutsu."

"It interferes with and influences a person's visual nerves, thereby deceiving their brain."

As he spoke, he pointed to a genjutsu on the scroll.

Demonic Illusion: Mist Servant Technique, a D-rank genjutsu, allows the target to see many terrifying phantoms. However, the phantoms have no attack power; they simply continue to split when struck.

The effect of this genjutsu is to disrupt the enemy's line of sight and attention.

This technique requires a total of three hand seals.

Genma raised his hands and slowly formed the seals, and then Yu Fenglan saw the study filled with his son's figures.

These were neither illusory clones formed by the Clone Technique, nor were these phantoms truly present in the room; rather, his vision had been affected by the technique.

Of course, Yu Fenglan saw through it easily, still able to precisely lock onto his son's true position.

However, to master the Demonic Illusion: Mist Servant Technique in such a short time, and to use it flexibly—not just to make him see so-called terrifying phantoms, but to create something akin to non-corporeal clones—this filled Yu Fenglan with immense joy. "Hahaha, as expected, son, you have inherited my wisdom."

"You didn't learn medical ninjutsu this quickly back then."

Genma curled his lip slightly, showing no hint of arrogance. "A genjutsu like this can only bully ordinary genin who have just graduated from the academy."

Yu Fenglan coughed twice. "You can't really say it like that."

"Ninjas who specialize in genjutsu are very formidable, such as the Uchiha Clan or the Kurama Clan of the past."

That was true.

One could only say that the ceiling for genjutsu is very high, while the floor is also very low.

However, genjutsu is merely one application of Yin Release nature transformation.

"Having mastered the Demonic Illusion: Mist Servant Technique so quickly, it seems the Demonic Illusion: Hell Viewing Technique and Demonic Illusion: Fox Spirit Technique shouldn't be able to stump you either."

Yu Fenglan felt slightly helpless.

There is one downside to having a genius son: as a father, one doesn't get much sense of accomplishment.

He hadn't even started teaching yet, and his son had already mastered a technique.

The remaining two were C-rank genjutsu, and he had only mastered these three genjutsu in total.

But in reality, that was quite a lot; after all, C-rank difficulty is effectively the standard for chunin.

Scratching his head again, Yu Fenglan said, "How about I teach you sensory ninjutsu first?"

"This is a bit harder than genjutsu."

Genma nodded.

The scroll was unrolled to the very end, and Yu Fenglan laughed. "This sensory ninjutsu didn't originally have a specific name; this one was coined by your old man. How about it? Isn't it quite good?"

Thousand Branch Spirit Touch.

Genma's eyelid twitched, and he nodded perfunctorily.

Although it was perfunctory, Yu Fenglan was satisfied, smiling as he said, "This technique uses oneself as the trunk, allowing your perception to grow outward like tree branches."

"These sensory branches cannot be seen by the naked eye, nor can they be touched by hand, but they can sense chakra."

"You should know, son, that chakra has mass."

"Looking at it through the summary you just made, these sensory branches also interfere with reality, but the wonder of it is that they cannot be blocked by the human body."

Genma nodded, lost in thought.
