At this moment, it's early January, the coldest time of the year, yet the morning chill can't quench the ninjas' fervor for training.
All the disciples' eyes followed Mokgetsu's arm movements, holding their breath as they watched him throw a punch, worried that any noise might affect his performance.
Mokgetsu didn't use any other abilities; he just transformed a large amount of Chakra into Armament Aura to harden his fist, wrapping the Haki around his fist.
He aimed at the riverside not far away and swung his fist covered in Armament Aura like an iron fist forward.
Whoosh whoosh!!
Just as Mokgetsu swung his fist, a fierce wind rose. Kakashi could feel the strong wind whistling past his ears, while the leaves were rustled by the gale, like a harbinger of an approaching storm.
Rumble!!
The next moment, a tremendous roar erupted, as if even the air had been blasted apart.
The shockwave caused by the swing instantly broke down the large trees in front of Mokgetsu, and even Shisui and the others behind him were affected by the powerful aftershock, struggling to stand firm without using Chakra to adhere to the ground.
"Such exaggerated punching power!"
Kakashi shielded his eyes from the flying wood chips and leaves blown by the wind, squinting at the shockwave that destroyed everything along its path, an uncontrollable look of shock on his face.
Kakashi had seen more than Obito and the others, but this scene was truly unprecedented for him.
Might Guy watched Mokgetsu unleash such terrifying destructive power with just a single punch and felt intense excitement in his heart.
Imagine if Mokgetsu had also used the Eight Gates or Breathing Technique; a single punch might pierce right through the entire Southern Border Forest.
"Equally excellent in both offense and defense, mastering this could be more important than learning several more Fire Release Ninjutsu," Shisui assessed inwardly.
Without a doubt, the importance of Armament Aura can be compared to that of Breathing Techniques.
"May Sage Mokgetsu bless me, enabling my cultivation of Armament Aura to be as smooth as Breath of Flame," Obito was already praying in his heart to successfully learn Armament Aura.
After destroying all the trees along the way, the powerful impact plummeted into the river with a loud bang, causing vast amounts of water and various river creatures to leap into the air.
Even Nohara Rin, who was training, paused for a moment, curiously glancing towards Mokgetsu.
Mokgetsu was quite satisfied with his control. Such an attack was eye-catching outside, but within the Southern Border Forest, which occupied 30% of Konoha's territory, it was just a minor stir.
"Besides choosing to enhance your body, you can also perform Armament Hardening on your weapons."
Mokgetsu canceled the Armament on his fist, pulled out a Kunai, and applied hardened Armament Aura to the blade, simultaneously wrapping the power of Armament Aura around the Kunai.
Mokgetsu casually chose a nearby rock and flung the Kunai towards it.
With a whistle, the Kunai flew swiftly towards the rock, shattering it upon contact.
"What a versatile Secret Technique!" Kakashi couldn't help but marvel. He initially thought having strong offensive and defensive capabilities was already impressive but didn't expect it could also be applied to weapons.
Kakashi felt this Secret Technique was very suitable for his swift and precise swordsmanship. The already sharp White Fang Short Blade, reinforced with Armament Aura, would be a waste not to slice through something hard.
Might Guy wasn't too affected, as he wasn't very skilled with Shuriken, and rarely used Kunai, relying primarily on hand-to-hand combat.
Shisui, however, had his eyes light up, feeling that the short blade Mokgetsu gave him would prove to be a great asset.
"As long as you cultivate the Secret Technique to a high level, you can enhance many things, even Ninjutsu."
Mokgetsu said as he extended his hand, concentrating a large amount of Chakra together for Lighting Release Chakra Nature Changes, and the brilliant purple lightning appeared in Mokgetsu's hand.
Mokgetsu had Kakashi summon the Earth Flow Wall, which he shattered with the Purple Lighting.
After destroying the Earth Flow Wall, Mokgetsu had Kakashi summon another Earth Wall using Earth Release.
This time, Mokgetsu didn't use ordinary Purple Lightning, but the Armament-enhanced Armed Lighting Release Purple Lighting.
Boom!!
Under the terrifying destructive power of the black-purple lightning, the wide, thick earth wall was immediately disintegrated, leaving only scorched black rubble.
Although both uses of Purple Lightning showed exceptional power, the four disciples could still clearly feel that the Purple Lightning enhanced with Armament Aura was much more powerful.
"This secret technique is too powerful, it can even enhance ninjutsu. Isn't learning it mean my overall strength will undergo a qualitative change?" Obito felt that this Armament secret technique taught by Mokgetsu was unbelievably strong.
The Breathing Technique is strong, but the Breath of Flame can only enhance Fire Release, and the Breath of Rock only excels in enhancing physical abilities.
Armament Haki is different. In terms of defense, it can withstand ninjutsu head-on; in terms of attack, a punch can be comparable to ninjutsu, and it can also enhance weapons and ninjutsu.
"Learning it can indeed greatly enhance your strength, but it's not as exaggerated as you think." Mokgetsu shook his head and said.
"First of all, Armament cannot enhance all ninjutsu. For instance, Fire Release techniques like the Great Fireball are difficult to enhance, and using Armament to enhance ninjutsu consumes a lot of chakra. Frequently using Armament to enhance ninjutsu in battle will consume a significant amount of chakra."
Obito oversimplifies things. While Armament is strong, it consumes chakra rapidly; if you don't have a ton of chakra, you can't sustain such consumption.
This is especially true for someone like Mokgetsu, who possesses numerous high-proficiency skills. He feels that even if his chakra reached two hundred thousand, it might not be enough.
High-proficiency nature changes can convert a significant amount of chakra at once, and the patterns from various Breathing Techniques also consume a lot of chakra. Now, there's also the perfect-level Armament Haki, a bottomless pit.
"Ah, so Fire Release doesn't work?" Obito scratched his head, suddenly feeling Armament Haki was not as overwhelming.
"It's not that Fire Release doesn't work, but most Fire Release doesn't." Mokgetsu corrected.
"Next, excluding Shisui, you three need to learn the nature transformation of Yin Release." Mokgetsu began to arrange the next phase of training.
Most ninjas are born with a chakra attribute, but this does not mean ninjas cannot master chakra nature changes outside their inherent attribute. Learning the nature change of a born attribute is usually faster and has a higher limit.
Of course, there are exceptions; having one more attribute or one less is possible. For example, Lee has no chakra attributes, whereas when Mokgetsu tested Might Guy's chakra attribute, he found that Might Guy had two inherent attributes: Lightning and Fire.
Even though Might Guy has two inherent attributes, learning ninjutsu is as difficult for him as it is for Lee, who has none. In that case, it's better to spend more time strengthening their physique.
The Yin and Yang attributes cannot be tested using chakra test paper, and Mokgetsu began teaching directly. However, to get the daily teaching reward return, Mokgetsu chose to personally teach Shisui Armament Haki and have a Shadow Clone teach Kakashi and the three others Yin Release chakra nature transformation.
"The essence of Yin Release relies on spiritual power to create form from nothing. It can be said that the core of using Yin Release is spiritual power." Mokgetsu explained.
If you see enigmatic and hard-to-understand ninjutsu in the world of Hokage, it's probably related to Yin Release, as it is all about creating from nothing.
As Mokgetsu continued to explain, Might Guy began to get confused. He recognized every word Mokgetsu was saying, but together, he couldn't make sense of it.
"Ahhh, it's so difficult!" Obito scratched his head, feeling that compared to Fire Release chakra nature changes, Yin Release chakra nature changes are really hard to grasp.
"So that's how it is, compared to the five major elements, it is indeed somewhat special." Kakashi showed an expression of sudden realization, gradually understanding Yin Release.
At this point, the differences in the three's ninjutsu talents became apparent. Although their potential was S-level, Obito and Might Guy's learning ability in ninjutsu was far below Kakashi's.
Although it was a Shadow Clone Mokgetsu, the proficiency in Yin Release and teaching level was solid, just without the benefit of teaching skill bonus.
On the other side, Mokgetsu's main body also began the formal teaching of Armament.
"Armament Haki is a Yin Release Ninjutsu. Yin Release Ninjutsu uses chakra and imagination to turn the intangible into tangible. When cultivating Armament Haki, you can imagine having an invisible armor on your body and then use chakra to manifest the armor." Mokgetsu said to Shisui.
"Invisible armor..." Shisui was lost in thought.
Armament Haki was more challenging than he expected. He originally thought that having learned Genjutsu, which is also a Yin Release, would make it simpler. However, he discovered the two are vastly different once he started learning.
"Don't apply your Genjutsu learning experience to Armament Haki; each Yin Release Secret Jutsu is quite different." Mokgetsu saw through Shisui's thoughts and reminded him.
Yin and Yang have been listed as two special kinds of nature transformation for a reason. The difference between the Great Fireball and Great Fire Extinguishing is just that Great Fire Extinguishing has more flames, and anyone can tell it's a Fire Release.
But if you perform Shadow Possession Jutsu and Mind Body Transfer Jutsu to someone who doesn't know about chakra nature transformation, no matter how much they think, they won't realize one controls shadows and the other invades the mind, yet these two belong to the same nature transformation.
The effects of different Yin Release and Yang Release Secret Jutsus are indeed worlds apart.
[You taught a student Armament Haki, and as the student was highly grateful, the reward critically increased, earning you the Earth Release: Heavyweight Rock Jutsu (Proficient Level)]
Received a ninjutsu unrelated to Shisui, but Mokgetsu was used to it. Teaching rewards don't always grant student-related rewards, just have a higher probability, and he once even got Water nature transformation from Might Guy.
It's considered a small burst; Heavyweight Rock Jutsu is a top-tier Earth Release Ninjutsu, capable of petrifying enemies, increasing their weight to slow them down, as well as enhancing one's weight to boost attacks.
As for the Super Heavyweight Rock Jutsu, it's essentially using Heavyweight Rock Jutsu with all one's might, not two separate techniques, similar to Super Almighty Push.
If Mokgetsu wished to condense all chakra into Armament and punch, he could also name it Super Armament Fist.
Similarly, the Shadow Clone Jutsu and Multiple Shadow Clone Jutsu, even though Multiple Shadow Clone Jutsu is a Kinjutsu, once you master Shadow Clone Jutsu, you naturally grasp Multiple Shadow Clone; however, generally, people won't use that much chakra for shadow clones.
