The second-year curriculum wasn't much different from the first year. The academic subjects remained the same, just more challenging. In the afternoon, the physical training class was no longer offered. By now, none of the students had been expelled, which meant they had all successfully extracted Chakra. As long as they followed the routine and endured the six years, they would either become Genin recognized by Jonin and receive the village's focused training or become new recruits for other departments. The likelihood of wasting six years and returning to being an ordinary person was extremely low.
Over the next five years, they would be taught skills like intelligence gathering and assassination. These lessons were of no difficulty to Izayoi and were even downright boring. After just a few days, he couldn't help but abandon his original plan and send a Shadow Clone to attend classes instead. Meanwhile, he stayed at home to train.
Although he couldn't practice the Five Elements Release Techniques at home, he could attempt to develop new Ninja Techniques. While creating Ninja Techniques typically required a strong foundation in Nature Transformation or Shape Transformation, as a transmigrator, Izayoi knew of one technique that didn't require such a foundation—only a sufficient amount of Chakra. That technique was the Rasengan, an attribute-less and signless Ninjutsu developed by the Fourth Hokage, inspired by the Tailed Beast Ball. It took him several years to create and was classified as an A-rank technique in terms of learning difficulty.
As Uzumaki Naruto's signature technique, which he used and developed into various forms throughout his life, the Rasengan was also the only technique in the original series that had its entire training method publicly revealed. That training arc left a deep impression. Anyone who enjoyed watching Naruto would never forget the training method, and Izayoi was no exception.
However, Izayoi wasn't practicing the Rasengan to use it as a trump card. Instead, as mentioned earlier, he wanted to use it as a foundation to develop a new technique. The Rasengan, being a signless Ninjutsu created by the Fourth Hokage, held special significance in the Leaf Village. Aside from the Fourth Hokage, only his teacher and students had mastered this technique. If Izayoi suddenly used it in the future, it would undoubtedly catch the attention of the Leaf Village's higher-ups. Without a reasonable explanation, it could lead to various suspicions, which was not what Izayoi wanted.
Therefore, he aimed to use the Rasengan as a base to develop another signless Ninjutsu—the Super Hurricane Consecutive Spheres, also known as the Multiple Giant Windstorm Rasengan. In the TV anime, this technique was used by Asura Otsutsuki to fight Indra Otsutsuki. It was similar to Naruto's Planetary Rasengan.
The principle of this technique was to first create an energy sphere slightly smaller than the Giant Rasengan, then add five smaller, rotating energy spheres of the same size as the Rasengan inside it. Like the Rasen Shuriken, this technique could be thrown or launched. Upon detonation, it would explode six times in succession. If the main energy sphere was destroyed, the five smaller spheres would scatter and attack the enemy. Additionally, just like Naruto's various elemental Rasengan variations, this technique could also incorporate the five elemental attributes or even combine them, similar to the Third Hokage's Five Release Great Barrage Technique. When that happened, its destructive power would be catastrophic.
If it weren't for the Otsutsuki Bloodline (Red) and the All Attributes Constitution (Purple) talents, Izayoi would never have dared to entertain such an idea. Simply mastering the Rasengan would have been enough for him.
However, the innate talent brought by the Otsutsuki Bloodline (Red), along with the All Attributes Constitution (Purple) and the Chakra Control that had already been upgraded to the purple level, gave Izayoi the capital to turn the original ninja techniques from the TV anime into reality.
With his powerful Chakra Control, Izayoi mastered the Rasengan in just one week.
Next, all he had to do was continue to infuse Chakra, expand the Rasengan to the size of a basketball, and prevent the energy sphere from exploding. Then, he could attempt to condense a small energy sphere within it.
However, Izayoi couldn't practice this stage at home. If the energy sphere were to explode, the consequences would be unimaginable.
Thus, he began to patiently wait for the day of the Uchiha Clan's downfall.
When May 15th arrived, Izayoi finally saw the day he had been waiting for.
In the afternoon, there were usually only two or three classes, and it would be several weeks before there was another Survival Exercise to test the students' growth during this period.
Even in such special circumstances, the school would dismiss around 5 PM.
But on this day, the second-year Class 1 students had an unusually long afternoon, attending four classes.
The final Survival Exercise didn't end until dusk had fully descended.
The Uchiha Clan's territory was located near the Naka River, practically indistinguishable from the outskirts.
Without using the Body Flicker Technique to hurry, by the time Uchiha Sasuke returned to the clan's territory, night had already fallen.
At this time, a full moon had already appeared in the sky.
Under the glow of the evening sunset, it looked somewhat blood-red.
Izayoi's Shadow Clone glanced at the back of Uchiha Sasuke, who had just left the school gate and was jogging home.
He knew that after today, this not-so-aloof, not-too-concerned-with-grades "Second Pillar" would completely disappear.
In his place would be a cold, emotionless figure who valued grades and family honor above all else, someone who could be easily provoked and emotionally destabilized with just a few words. This version of "Second Pillar" would soon stand before Izayoi.
Although the latter's fate was tragic, Izayoi was still eagerly anticipating that moment.
After all, he had waited an entire year for this.
…
The next day, news that shocked the Leaf Village spread rapidly, and through the communication of spies, it quickly reached every corner of the Shinobi World.
After the decline of the Senju, the Uchiha Clan had become the foremost noble family in the Leaf Village, and even the top ninja clan in the Shinobi World. Their Kekkei Genkai, known for its one-on-one invincibility, Copy Eye, and Genjutsu Eye, had suddenly been wiped out.
The perpetrator of this clan's destruction was not their rival, the Hyuga Clan, nor the Leaf's higher-ups or other ninja villages. It was the eldest son of the Uchiha Clan's current leader, the 13-year-old Uchiha Itachi.
In the following days, the name Uchiha Itachi spread rapidly across the Shinobi World, making him the youngest S-rank rogue ninja in the Leaf Village, and perhaps the entire Shinobi World.
As soon as Izayoi stepped out of his house that day, he saw villagers discussing the incident.
This was a major event.
Its impact was no less significant than the Nine-Tails' rampage in the 48th year of the Leaf.
In just a few short years, the Leaf had lost the Fourth Hokage and his wife, along with a host of powerful figures, as well as its foremost noble ninja clan.
Now, the Leaf Village had undoubtedly entered its weakest period since its founding.
Once a Ninja Village with so many Kage-level strong that one couldn't count them on one hand, capable of winning against four enemies at once, now only has the aged Third Hokage as its sole Kage-level strong.
After the Nine-Tails' rampage, the Leaf Village attracted the covetousness and schemes of the Cloud Ninja.
Now, having lost its foremost Ninja Clan, it should logically have drawn the attention of even more external enemies.
Yet, surprisingly, the Leaf Village remained peaceful for the following years.
Clearly, the major Ninja Villages had noticed something amiss.
