After Mokgetsu sealed the Dragon Vein Energy into the Chakra Armor of the Snow Country, the armor's amplification of Ninjutsu power received a significant boost.
However, this enhancement still had an upper limit. When Mokgetsu attempted to fully unleash a Perfect Level Nature Transformation Fire Release Ninjutsu, the armor's amplification became negligible.
Nevertheless, this was still a worthwhile discovery. Mokgetsu couldn't use it, but he could give it to Kakashi and the others.
...
"Brother Mokgetsu, I think I'm feeling the difference you mentioned." On the first noon of officially practicing the Breath of Yang, Uzumaki Naruto said to Mokgetsu with a face full of joy.
Mokgetsu used the Identification Jutsu to take a glance at Uzumaki Naruto.
[Name: Uzumaki Naruto]
[Skill: Breath of Yang (1/100)]
Whether it was because of the extensive time spent on theory or Naruto's own talent, his progress was rapid, achieving proficiency within a few hours.
Naruto, having found the right path for cultivation, directly used the Shadow Clone training method, splitting into over twenty shadow clones to practice Breath of Yang.
After a period of cultivation, Naruto canceled the shadow clones to organize the training memories. In Mokgetsu's assessment, Naruto's Breath Technique proficiency soared to six points.
Although over twenty shadow clones couldn't give Naruto more than twenty times the training speed, this training efficiency was indeed astounding.
Mokgetsu had anticipated this. In the original story, Naruto didn't take long to go from having no understanding of Wind Attribute Chakra Nature Changes to developing an S-level Wind Release. It can only be said that compared to ordinary ninjas, Naruto truly had an edge.
On the second day of officially practicing Breath of Yang, Naruto's proficiency had already surpassed Yamato, who had started practicing Breath of Water earlier, allowing him to initially enhance his power in battle using the technique.
Around four in the afternoon, Mokgetsu called off Naruto and Kakashi's training, directing them to switch to battle training.
All three of Kakashi's team were full of enthusiasm. It had been quite some time since their first battle, and while they might not defeat Uzumaki Naruto, they certainly wouldn't lose as miserably as before.
Uzumaki Naruto was also very eager. During the lessons, besides learning the theory of Breath of Yang, Mokgetsu had also taught him a lot of Taijutsu, making this a good opportunity to test his training results.
This time, Naruto did not directly use a shadow clone barrage tactic, but first engaged one-on-three head-on.
During this month, Obito's Breath of Flame Chakra Mode had made significant progress. Like Mokgetsu, he could now clap his hands to use whichever Ninjutsu he desired.
In the battle, Obito turned into a Fire Release cannon, launching several high-power Fire Releases, causing considerable trouble for Naruto.
Kakashi's speed had increased, and his powerful Lighting Release slashes forced Naruto to create many shadow clones to divert Kakashi's attention.
The monster strength power Nohara Rin displayed reminded Naruto of Sakura.
Watching their battle, Yamato couldn't help but nod approvingly; everyone had visibly progressed.
Yamato glanced towards Mokgetsu's direction, immensely impressed by Mokgetsu's teaching skills.
This glance left Yamato a bit bewildered.
"Two Brother Mokgetsus?" Yamato just then noticed a man standing next to Mokgetsu who bore an uncanny resemblance to him.
Noticing Yamato's gaze, Namikaze Minato turned his head and smiled at Yamato.
Upon seeing Namikaze Minato's face clearly, Yamato instantly confirmed that this was the Fourth Hokage himself.
Mokgetsu wore black-frame glasses, while Minato did not. With this distinction, Yamato could differentiate them well.
Yamato somewhat understood a bit of Obito's feelings: they looked so alike, carried a similar aura, claiming they were brothers wouldn't be questioned by anyone.
"Should I stop them?" Mokgetsu asked.
"No need, the battle is about to wrap up." Minato shook his head with a gentle smile, replying.
Although both Obito with the Breath of Flame Chakra Mode and Kakashi with the activated Transparent World were not weak, they couldn't maintain it for long. It was different for Naruto; as long as he didn't use the Rasen Shuriken, his Chakra would be abundant.
But certainly, Naruto wouldn't use the Rasen Shuriken in a training battle – it could be deadly.
"Brother Naruto, as expected, you're still the stronger one." Obito conceded, sincerely convinced.
Kakashi panted heavily, acknowledging in his heart the distance between them and such powerful Jonin.
"After all, I'm much older than you guys." Naruto scratched his head and laughed.
After a very harmonious post-battle discussion, Naruto turned back to look at Mokgetsu, wanting to know his opinion, then saw Namikaze Minato standing next to Mokgetsu, smiling warmly at him.
