"Because novels are inherently fictional, only someone with a problem would expect real people to be as perfect as fictional characters," Kakashi retorted bluntly.
"Haven't you heard the saying, 'novels are derived from reality'!" Obito countered.
Seeing Obito and Kakashi quickly getting into another argument, Uzumaki Naruto chuckled. He and Sasuke often did the same, just that now...
With An Lushan sealed and detained, there was no need to investigate at night, so Uzumaki Naruto used this time to teach Obito the Rasengan.
Since Obito wanted to learn, Uzumaki Naruto genuinely taught him.
"The primary factor of the Rasengan is rotation; its essence is highly rotating chakra!" Naruto began with a simple explanation of the Rasengan's principles.
"Yes, yes, and then?" Obito asked eagerly, nodding.
"Rasengan!"
Uzumaki Naruto wasted no time demonstrating, gathering a large amount of chakra in his hand to form a Rasengan, smashing it directly against a tree created by Yamato's Wood Release.
Boom!
A huge gap appeared instantly in the tree, sending wood chips flying everywhere.
"The Rasengan is not a complete ninjutsu; incorporating nature transformation can make it stronger," Uzumaki Naruto briefly mentioned his Rasen Shuriken.
Due to the massive power of the Rasen Shuriken and the damage it could cause to his body, Uzumaki Naruto didn't demonstrate it, only explaining it briefly.
Obito grew even more excited, remembering the combined technique he and Uzumaki Naruto accidentally performed today. If he could accomplish it alone, it would be like gaining another powerful ninjutsu.
"Learning the Rasengan involves three parts; start by practicing with this water balloon," said Naruto as he pulled out a balloon filled with water.
"Then just bam and pop, make it burst."
As soon as Naruto finished speaking with sound effects, the water balloon in his hand burst.
"Whoa, Naruto bro, how did you do that just now?" Obito asked, eyes wide, feeling he hadn't caught on.
"I said, bam and pop," Uzumaki Naruto repeated, thinking perhaps Obito hadn't heard him earlier, so he raised his voice a little.
Obito: ...
Obito stared blankly at Uzumaki Naruto.
Seeing Obito's expression, Naruto scratched his head and pulled out another water balloon.
"It's just bam and pop, such a simple thing."
The water balloon once again burst with Naruto's sound effects.
Obito was dumbfounded. Could anyone really learn ninjutsu this way?
Obito thought he might just remember Uzumaki Naruto's words and tell Mokgetsu, letting Mokgetsu develop it before teaching him. That might be faster.
...
Land of Grass, Konoha Camp.
"Mokgetsu, what brings you here? What mission did you take?" Jiraiya asked with a hearty laugh upon seeing the approaching Mokgetsu.
The more powerful ninjas on the battlefield, the easier it was for him. Naturally, he welcomed Mokgetsu's arrival.
Mokgetsu didn't immediately respond to Jiraiya but surveyed the surroundings.
Understanding Mokgetsu's intent, Jiraiya entered a meeting tent with Mokgetsu for a private conversation.
"It's not a mission; it's a private matter related to you, Jiraiya-sama," Mokgetsu began.
"Oh? What matter would make Mokgetsu come this far to the front lines to find me?" Jiraiya asked, puzzled.
He couldn't think of any personal matter that would draw Mokgetsu all the way to the battlefield.
"A ninja from the future wants to meet you," Mokgetsu didn't play the guessing game and directly mentioned Uzumaki Naruto's existence.
"A ninja from the future? Mokgetsu, I didn't expect you to have such a great sense of humor," Jiraiya laughed.
But then Jiraiya's smile gradually faded away because Mokgetsu's expression didn't change at all, not looking like he was joking.
In fact, Jiraiya didn't think Mokgetsu would joke about something like this, but it was indeed hard to believe.
This wasn't like a prophecy; if one could freely travel through time, history would be in chaos.
"Who is he? If he wants me to meet him, he should at least have a name," Jiraiya asked calmly.
"Uzumaki Naruto, the Nine-tailed Jinchuriki of the future Konoha and the future disciple of Kakashi," Mokgetsu replied after some thought.
"Uzumaki? Jinchuriki?" Jiraiya squinted his eyes, diving into thought.
Currently, Konoha has only one member with the Uzumaki surname, and that's Minato's girlfriend, Uzumaki Kushina.
But this Uzumaki Naruto might not necessarily be related to Minato; after all, Minato's descendants should bear the name Namikaze. Perhaps he was a surviving member of the Uzumaki Clan who joined Konoha.
But the Nine-tailed Jinchuriki point was worth pondering. A Jinchuriki could only be replaced if the previous one died, meaning Kushina would have to die for this Uzumaki Naruto to inherit the role.
"I think he might be Minato's child," Mokgetsu expressed his 'guess.'
"He knows a ninjutsu that Minato is still developing, and he bears a slight resemblance to Minato."
At the moment, Uzumaki Naruto himself didn't know his father was Namikaze Minato, so Mokgetsu could only say it was his guess.
Jiraiya furrowed his brow. To resemble Minato and know the ninjutsu Minato is developing, and with the Uzumaki surname, it seems almost confirmed.
If it were just the first two points, it could also apply to Mokgetsu, considering the Rasengan is nominally developed by both him and Minato. However, the Uzumaki surname wasn't related to Mokgetsu.
"The war is at a critical juncture; I can't get away," Jiraiya clarified after sorting out his thoughts.
Mokgetsu didn't speak. There was a way to meet without affecting the battlefield, and Jiraiya knew it.
"I'll send my Shadow Clone with you," Jiraiya said, forming a seal and creating a Shadow Clone.
In the world of Hokage, being spread thin isn't an issue, as people here can truly create clones.
