Land of Rain.
The third day of unrestricted lectures.
Because of the buzz from the first two days, more Ninja rushed to the Land of Rain by reputation, wanting to see whether Ninja Master Sosuke's teaching ability was really as formidable as the rumors said, so the number of listeners increased further.
Of course, the arrival of more people also increased the management difficulty for the Ninja Sect.
After all, the Ninja Sect only had just over a hundred Ninja right now; trying to manage over a thousand Ninja was still quite the challenge.
However, the Ninja who had attended the lectures for the past two days were worried that if they offended the Ninja Sect they wouldn't be allowed to continue attending, so they all behaved very honestly. Thus, no real chaos occurred; anything that did happen was basically stopped as soon as it began.
"Ninjutsu is a combination of Chakra Nature Changes, Chakra Form Transformation, and Chakra Control!" Mokgetsu concluded.
"Whether it's Fire Release or Water Release, or Yin Release Ninjutsu and Yang Release Ninjutsu, in essence they are all the same."
This was also why there could be such huge differences when different people used the same Ninjutsu.
Some people needed to run through the full set of Hand Seals to use a Ninjutsu, some could simplify the seals, some only needed a single seal, and some didn't even need seals.
Because their abilities in Nature Transformation, their ability to control Chakra, their understanding of the Ninjutsu itself, and so on, all differed.
Mokgetsu's words plunged many people into thought.
Most Ninja did not have this kind of understanding.
Because when Ninja first come into contact with Ninjutsu, there are roughly three common situations: one is the Ninja Academy, the second is the internal training systems of a Ninja Clan, and the third is instruction from elders in Ninja families.
In these three major categories, no matter which one, the educators are at most ordinary Jonin, and in most cases they are Chunin.
And what level is a Chunin? A Chunin who's learning Fire Attribute Chakra Nature Changes and can use Great Fireball plus Phoenix Sage Fire is already considered quite outstanding; how could they have any grand, overarching insights?
"What a pity I didn't come the first two days." The Ninja who only came to the Land of Rain to listen on the third day had a face full of regret.
Just from Mokgetsu's opening sentence he knew he hadn't come in vain.
"Of course, this doesn't mean we can just randomly combine things to develop Ninjutsu." Mokgetsu continued.
"Different Chakra Nature Changes have different characteristics: fire's high-temperature combustion, wind's cutting, water's mutability. In terms of Chakra Nature Changes, we can develop based on the characteristics of different Chakra Nature Changes."
"For example, with Water Attribute Chakra Nature Changes, we can use Chakra Form Transformation to make it sharper and increase its Penetration Power, or turn it into Water Mist to obstruct vision."
Mokgetsu's experience with all kinds of Ninjutsu was simply too rich. Although counting the original body he had only cultivated Ninjutsu for a bit over ten years, once you added in the cultivation memories instilled by the system, it became exaggerated.
Every time he obtained a new Master Level Ninjutsu, Mokgetsu had a feeling like he had cultivated that particular Ninjutsu for several years, even more than ten years.
Even though it was just an illusion—only a second had actually passed in reality—the cultivation experience in Mokgetsu's mind was solid and real.
So no matter what kind of Ninjutsu it was, Mokgetsu could talk about it with ease; his content was solid, and at the same time he distilled new insights out of it.
"This is what a true Ninja Technique Professor is." Hanzo sighed in his heart.
At this moment he no longer felt any resentment over losing to Sosuke. The day's course had only gone about halfway, and just from the tip of the iceberg Sosuke had revealed, Hanzo could already sense how terrifying Sosuke was.
When a Ninja has mastered seven Chakra Nature Changes and also has deep research into all Ninjutsu, then it's almost impossible for him to be countered in battle, and he can always use abilities that counter the opponent.
Hanzo had once thought Sosuke only excelled at Fire Attribute Ninjutsu, which was why he fought him using Fire Attribute Ninjutsu that were countered.
Looking at it now, Sosuke had simply been confident at the time, believing Fire Attribute Chakra alone was enough to defeat him; there was no need to use other abilities.
Hanzo showed a trace of lonely expression; realizing this was hard for him.
He had valued Sosuke so much, treating him as a great enemy, and after being defeated had wrestled with himself countless times in his heart, only to discover in the end that Sosuke hadn't taken him seriously at all and hadn't even gone all out in that fight.
Hanzo pressed down the unnecessary emotions in his heart and continued listening. He could think about things later, but if he zoned out during class, Sosuke definitely wouldn't reteach it just for him.
When the class ended, Hanzo prepared to return to the Rain Village. He had already been away from the Rain Village for three days; it was about time to go back.
"Tomorrow morning's class will still be Ninjutsu, but there will be more content on Chakra Control. In the afternoon, it will be Taijutsu." As usual, Mokgetsu gave a preview.
Hanzo fell into thought. He had felt something was missing, and now realized it hadn't finished yet.
"Since I've already stayed three days, I might as well stay half a day more." Hanzo decided to leave tomorrow afternoon instead, at least finish listening to the Ninjutsu portion.
It was like a novel with three volumes—upper, middle, and lower—and he was just short the last one. Even if it wasn't some huge loss, it would still feel uncomfortable.
The next afternoon, Hanzo was curious about what level Mokgetsu's Taijutsu was at. He planned to listen for just a few minutes then leave, but after he started listening he was instantly stunned as if seeing a heavenly being, and by the time he came back to his senses, the afternoon class had already ended.
"Hanzo, you're the leader of the Rain Village; how can you neglect village affairs because of Sosuke's lectures? Have you forgotten the great aspiration of the rise of the Land of Rain?" Hanzo reminded himself in his heart and resolved to leave immediately after finishing the next morning's class.
On the fifth day, he attended lectures all day.
On the sixth day, he attended lectures all day; there were more and more people, and he didn't manage to grab a seat near the front.
On the morning of the seventh day, Hanzo stood in front of the mirror in his inn room, staring at himself in disbelief. A full seven days had passed and he hadn't returned to the Rain Village even once.
