Why the Uchiha Clan Laughs Maniacally in the Middle of the Night

"Generally speaking, nature transformation and shape transformation are broadly divided into three types. The first type involves changes to the ninjutsu itself. Taking Fire Style as an example, the Fire Style: Ash Pile Burning belongs to this category; it doesn't simply convert chakra into flames, but rather into gunpowder, which is then triggered to explode."

"Meanwhile, Fire Style: Phoenix Sage Flower Nail Crimson is a classic example of shape transformation. It has stronger adhesion than ordinary flames, which is why it can be attached to shuriken."

"It is precisely for this reason that although Ash Pile Burning and Phoenix Sage Flower Nail Crimson are only B-rank ninjutsu, they still require a three-tomoe Sharingan or a two-tomoe Ninjutsu Eye to copy. 'Secret Techniques' are ninjutsu that have such high requirements for these transformations that even the Sharingan cannot copy them directly."

"The other two types involve the user themselves causing the ninjutsu to undergo nature transformation. For instance, if we both use the Great Fireball Technique, the temperature and range will be completely different depending on whether I use it or my father uses it. This isn't just due to the output of chakra, but also because my father has altered the nature and shape of the Great Fireball Technique..."

"One type is directed at changing a specific ninjutsu, while the other involves a fundamental change in the nature of one's own chakra. Once that happens, the temperature of all Fire Style techniques used will be higher."

"In fact, the third type—fundamentally changing the nature of one's own chakra—is the foundation for the birth of a Kekkei Genkai. If the change in one's own chakra reaches the level of a 'Secret Technique,' it will cause the body itself to change, and this change has the potential to be passed down through reproduction," Fugaku said.

After listening to Fugaku, Akaseki had a much clearer concept in his mind.

One way is to directly learn special ninjutsu from predecessors, which is relatively the simplest; another is to modify a specific ninjutsu yourself, which, when pushed to the limit, forms a "Secret Technique" that transcends its original attributes; the last is the metamorphosis of one's own chakra, which is effective for all ninjutsu of that attribute. When pushed to the limit, this forms a new chakra attribute that influences the body and can be inherited—this is a "Kekkei Genkai"!

Akaseki had actually known about this type of chakra-based Kekkei Genkai for a long time.

In the eyes of the Uchiha clan, a Kekkei Genkai that only involves chakra nature transformation is naturally "not worth a single strand of hair on the Sharingan."

However, when viewed across the ninja world, even the most ordinary chakra-based Kekkei Genkai is enough to make people look at you with respect.

Akaseki asked with a puzzled expression: "I remember reading somewhere that this kind of Kekkei Genkai requires two types of chakra to be mixed, right?"

Fugaku corrected him: "It should be said that it 'usually' requires the mixing of two types of elemental chakra to achieve such a massive change, but it's not like there are no examples of single-attribute mutations... In fact, theoretically, within the Uchiha clan, there is also the Scorch Style Kekkei Genkai, which is simply the alienation of pure Fire Style chakra."

"It's just that because Kekkei Genkai ninjutsu cannot be directly copied, clan members usually don't put much effort into this area," Fugaku said, shaking his head helplessly.

Indeed, with so many Fire Style users in the Uchiha clan, statistically speaking, a Kekkei Genkai derived from "Fire Style" would accumulate over generations...

It's just that the Uchiha clansmen are generally uninterested in this, so it has always remained a recessive trait, only occasionally manifesting.

After all, when you can copy large batches of Fire Style techniques, who has the heart to worry about Scorch Style or whatever else...

"Generally, to train in nature transformation, you either find ninjutsu that already possess nature transformation and learn from them to summarize your experience, or you practice more and think more..." Fugaku returned to the topic of training.

Akaseki immediately focused his attention—since there was a "generally," there must be a "special"!

Sure enough, Fugaku continued...

"However, for us in the Uchiha clan, there is actually a simpler... or rather, a different method." Fugaku paused here, seemingly unsure if this counted as "simple," then continued: "The Sharingan is the power of the heart, the power of emotion. Naturally, the ocular power of the Sharingan can also influence the essence of chakra."

Upon hearing this, Akaseki thought to himself, As expected of my great Uchiha clan, while hurriedly asking: "What should I do?"

Fugaku shook his head and said: "This is already a relatively high-end technique, especially since it consumes too much ocular power. Even within the clan's heritage, it isn't as systematic as basic abilities; one can only say there are some tricks to it."

"In general, it involves activating the Sharingan during moments of emotional agitation and visualizing the type of chakra transformation you desire. Over time, the chakra of the corresponding attribute will be influenced..."

"According to the experience summarized within the clan, for Fire Style chakra, the four emotions of joy, anger, sorrow, and happiness will all change its nature and shape."

"Happiness can increase the spread speed of Fire Style; anger can increase the temperature of Fire Style; sorrow can make the flames formed by Fire Style harder to extinguish; joy can increase the range of Fire Style."

This method of training consumes a great deal of ocular power, and furthermore...

It requires accumulation over time rather than achieving success overnight. Frequently agitating one's emotions can also damage the mind, so it isn't widespread within the Uchiha, and naturally, not that much has been summarized.

Since Fire Style is the most common in the Uchiha clan, it is naturally the most specifically documented.

After pondering for a moment, Akaseki asked curiously: "Brother Fugaku, what is the difference between 'happiness' and 'joy'?"

"'Happiness' leans more toward genuine satisfaction and delight; 'joy' leans more toward a momentary thrill. You can understand it this way—happiness is a knowing smile; joy is unprovoked, wild laughter," Fugaku provided as an example.

"I see!" Akaseki felt the example was very clear.

At the same time, Akaseki thought...

The Fire Style ninjutsu of everyone in the clan generally isn't very easy to hit opponents with, leading some to privately criticize that Uchiha Fire Style doesn't kill.

Thinking about it now, that's because the speed isn't enough!

However, the range is always prominent, especially with the ancestor Madara Uchiha; it is said that one Fire Style technique can burn down an entire city!

Akaseki hadn't thought much of it before, but now, after hearing Fugaku's words, he had a sudden realization—indeed, there is plenty of "Uchiha wild laughter" in the clan, but very few "Uchiha knowing smiles"...

At the same time, Uchiha Fire Style is usually "hot means fierce, big means strong"... now it seems that is also a result of their personalities.

After listening to Fugaku's "little tricks for using the Sharingan to change the nature and shape of Fire Style," Akaseki's mind was churning...

After dinner, Akaseki ran to an empty training ground and couldn't wait to start trying.

Of course, he wasn't going to laugh wildly for no reason, but rather... enter the "Immersive Short Drama Experience Platform"!

Akaseki wanted to know: when emotions are forcibly led during an immersive experience, can those thoughts serve as nutrients for nature and shape transformation?

Even though he was curious, Akaseki still forced himself to do physical training first to drain his stamina, so as not to waste it, and then he "immersed" himself.

While "immersed," although Akaseki couldn't gain complete control—he couldn't even hit people, and the Sharingan was even more ineffective—but... it wasn't that he couldn't activate his eyes; it was just that they weren't displayed in the "short drama." He could still activate his eyes physically. By the same token, he could actually silently practice his chakra control at this time...
