"Ding~"

Genjutsu.

As a relatively weak link among the many arts of a ninja, it has rarely appeared on the front lines.

Or rather, because of the Uchiha clan and the existence of the Sharingan bloodline, genjutsu has long been regarded as a supporting skill for special ocular techniques. Consequently, outside of ninja clans possessing specific bloodlines, it is extremely rare to find ninjas who build their combat systems around this path.

Furthermore, the learning threshold for genjutsu is no lower than that of other elemental ninjutsu, and the corresponding methods for breaking them are relatively standardized.

This means that if a genjutsu technique, which requires great effort to master, cannot kill the enemy in one strike, it is often easily dispelled by multiple opponents!

...Even the Great Fireball Technique, famously known as the "kindly ninjutsu that never kills anyone," can at least produce some sound and light effects!

From this perspective, rather than putting great effort into creating illusions, it is more cost-effective to invest the same amount of chakra into lethal ninjutsu.

--But even with the many limitations of genjutsu, it did not shake Yamada Soji's determination to learn new skills!

It was not that Yamada Soji was convinced of his own extraordinary talent or that he would definitely make a name for himself in the field of genjutsu... it was simply that, based on the personal demonstration by Nara Motonari, the boy's understanding of genjutsu had undergone a fundamental change.

He realized that what he needed was not high-level weapons of mass destruction like Infinite Tsukuyomi, Izanagi, Izanami, or Kotoamatsukami.

Instead, those ordinary genjutsu that seemed to have average effects but possessed high versatility and lower learning difficulty could, when combined with his current combat system centered on Accio, actually compensate for each other's weaknesses and exert unexpected power!

Thus, with a clear learning goal, Yamada Soji asked Nara Motonari for the usage methods of a series of D-rank genjutsu, including Demonic Illusion: Hell Viewing Technique, Demonic Illusion: False Surroundings Technique, and Demonic Illusion: Temple of Nirvana. He tried them one by one, testing his compatibility with these new skills.

Such a learning method was clearly uncommon, and from the perspective of a supervising jonin, Nara Motonari, who was well-versed in the ways of genjutsu, had quite a few complaints about the boy's "cast a wide net" approach.

"The practice of any technique requires a step-by-step approach; trying to become an expert overnight will likely lead to half the result with twice the effort."

Based on Nara Motonari's personal experience, the study of genjutsu should focus on breaking through a single point, mastering one technique first, and then expanding outward by drawing inferences from it.

However, unexpectedly, Yamada Soji, who had always been respectful to his teachers, did not listen to his teacher's earnest teachings this time...

The boy knew in his heart that his ultimate goal was not to master a specific low-level genjutsu, but to extract useful elements from the effects of different techniques and integrate them into his skill set, which was currently centered on Rain Woman's Heart.

To this end, he did not need to practice Demonic Illusion: Hell Viewing Technique until he could perfectly manifest the images of an enemy's inner fears; nor did he need to master Demonic Illusion: Temple of Nirvana to the point of instantly creating a realistic, otherworldly illusion.

What Yamada Soji needed to do was to intercept the emotion-guiding methods of Demonic Illusion: Hell Viewing Technique and utilize the visual deception principles of Demonic Illusion: False Surroundings Technique, ultimately synthesizing these characteristics to arm his original attack methods, aiming to maximize strengths and avoid weaknesses.

Therefore, rather than the proficiency of any single ninjutsu, he cared more about how to grasp the more regular "basic axioms" contained in these low-level genjutsu and transform them into a form better suited for his own use.

For Yamada Soji, who was good at logical deduction, this process was actually more time-saving than honestly mastering each specific genjutsu.

But what surprised Yamada Soji was that this decision, which was originally based purely on rational thinking, achieved unexpected results on the second day after he started practicing!

--The golden finger, which had been silent since it provided the usage method for "Accio" on his 11th birthday, suddenly changed.

It seemed to sense the boy's thirst, and after nearly a year of silence, it once again presented him with a great gift!

A chubby Scottish Round-Faced Fat Chicken flew across his mind with an envelope in its beak.

The letter, bearing the totems of the four Hogwarts houses, then unfolded automatically!

However, compared to the admission letter from a year ago, the content of this letter was much richer.

Dear Mr. Yamada Soji:

We are pleased to inform you that the new semester begins today. Attached is a list of optional spells; we hope you will study hard and successfully complete your coursework.

Energy Purity: E

Unlocked Spells:

Accio √

Confundus Charm √

Man proposes, God disposes.

Over the past year, Yamada Soji had spent all sorts of effort hoping to unlock more spells through the golden finger to strengthen his power, but he had never been able to get his wish.

Who would have thought that just when he was about to give up hope on his cheat, things would take a turn for the better.

Although the newly unlocked "Confundus Charm" did not have direct lethality, as an auxiliary spell that could affect a target's judgment and cognition, it happened to be quite similar to the genjutsu Yamada Soji had been studying recently!

Compared to traditional ninjutsu that required careful study to master, the spells provided by the golden finger were basically only linked to energy purity in terms of their effects.

This gave Yamada Soji a chance to overtake on a curve!

He no longer needed to fully understand the underlying principles of the several entry-level genjutsu he had just learned from Nara Motonari.

Instead, he used these mature ninjutsu models, formed after generations of ninja improvements, as a shell, and then filled their core with the Confundus Charm, effectively achieving an organic combination of auxiliary genjutsu and main combat ninjutsu!

Of course...

When he had more time in the future, the boy would also develop supporting usage modules for the newly acquired Confundus Charm, just as he had modified Accio, striving to maximize its effects.

The current method of forced stitching could only be considered a stopgap measure, without any consideration for future development needs.

But precisely because of this, this splicing method, full of the pragmatic style of an orc technician, gave the new technique a certain rough and wild charm, and in a short time, it had transformed the original "Rain Woman's Heart" beyond recognition...

--Fortunately, judging from the results, the power of the bloodline secret technique had indeed been greatly enhanced!

But the versatility issue that Yamada Soji had expected at the beginning of learning genjutsu was not only unresolved but had become even more severe.

So much so that when the boy privately demonstrated the improved secret technique to Nara Motonari, even the Nara Commander, as his instructor, was left feeling quite confused...

"Have I lost my memory, or have I reached the age of senility..." Teacher Nara Motonari stood with his left hand on his hip and his right hand scratching his head, falling into immediate self-doubt: "What on earth did I teach you yesterday?"

Unable to reveal the truth, Soji could only dodge the question, circling around trivial details instead.

"Although the actual visual effect looks vastly different, the new technique is essentially a modified ninjutsu reconstructed from the two D-rank illusions, Demonic Illusion: Hell Viewing Technique and Demonic Illusion: Temple of Nirvana. Its underlying logic hasn't undergone any fundamental subversion..."

"...What kind of nonsense are you spouting at me, you little brat?" Nara Motonari covered his face with his hand, caught between laughter and tears.

He would stake his reputation as a jonin instructor on this! The genetic relationship between the new gadget his student had cooked up and the Demonic Illusion: Hell Viewing Technique could not possibly be greater than the connection between a ham and a ham sausage...

"Come clean, what is actually going on?"

"...Alright, the truth is that I felt the existing techniques weren't quite suitable yesterday, so I made a few small changes in private." Soji pinched his right hand into an 'L' shape, using body language to vividly illustrate the extent of his modifications to the original technique.

"How much did you change?"

"Just a little bit."

"How much, really..."

"It really was just a little bit."

"..."

Teacher Motonari maintained a silent stare, expressing his dissatisfaction with his student treating him like a fool.

And for the first time, the young man felt the troubles brought about by his cheat.
