In Natsuki's opinion, Kakashi was doing it on purpose.
Clearly, hearing him say he was going home to cook for his girlfriend made him jealous for a moment, and then he deliberately assigned him the mission.
At a time like this, shouldn't the single dog voluntarily take on this mission? After all, a single dog goes home to a cold and lonely house anyway, so wouldn't it be a good deed for them to take the mission and let others go home to be with their partners?
Of course, when Natsuki was handing out the sunglasses just now, Itachi Uchiha did indeed use Genjutsu on Natsuki.
The reason it didn't work might be because of his golden finger.
Natsuki had been researching Ninjutsu for so long that he had long since discovered he was immune to Genjutsu. This was likely because the gravity lab was in his mind, and Genjutsu clearly couldn't shake the lab.
In this way, Natsuki was a BUG!
Let alone Itachi Uchiha's Tsukuyomi Genjutsu, even Infinite Tsukuyomi probably wouldn't work.
However, Natsuki couldn't tell others about this, so it was fine to let others think he just had high Genjutsu resistance. It's just that this meant he really had to go on this mission, after all, he was clearly more suited to dealing with Itachi Uchiha.
Didn't Kakashi get tortured by Itachi Uchiha's Genjutsu for three days and three nights?
Asuma Sarutobi and Kurenai Yuhi could only close their eyes at that time!
Only Natsuki was fine!
Moreover, Natsuki's current strength was recognized by a group of Jonin, so even though he was just a Genin, sending him on a mission alone didn't seem to be a problem.
Fortunately, Kai arrived at this time, so the final decision was to have Natsuki and Kai go together.
Natsuki couldn't object either, and could only ask Kakashi to help pass a message to Tenten. He didn't know how many days it would take to return from this trip, so he couldn't let his family worry.
"Since that's the case, we're leaving." Natsuki and Kai were about to depart.
"Natsuki, wait a moment!"
Sasuke suddenly spoke, "Um, how did you do that Sun Fist earlier?"
Kakashi, Asuma Sarutobi, and Kurenai Yuhi were also very curious. After all, a move that could make one's body emit a strong light was very powerful. It could play a particularly big role when used unexpectedly, as seen from how Kisame Hoshigaki was almost beaten to death, and even Itachi Uchiha was accidentally affected.
Natsuki smiled and said: "It's not really a secret. You need to know how to think, Sasuke. In Earth Release, there's a Hardening Technique, which uses Chakra to absorb the properties of rock into the body to harden it. And I had a flash bomb on me. Can you understand if I say it like that?"
Sasuke suddenly realized: "You absorbed the properties of the flash bomb into your body to make yourself glow!"
"That's right! Well, I'm leaving."
Natsuki nodded to everyone and chased forward with Kai.
Sasuke, meanwhile, fell into deep thought. He felt he wasn't very good at thinking. The Sun Fist had such a simple principle, yet he couldn't figure it out. He was still a bit too slow.
But thinking about it carefully, it seemed Natsuki was just too smart. After all, the Hardening Technique wasn't rare; many Ninja who could use Earth Release knew it. But so far, only Natsuki had thought of absorbing the properties of a flash bomb to create the Sun Fist. Perhaps, it was because other people generally didn't have such flexible thinking.
"Training, learning, drawing inspiration, imagination. This Sun Fist is the result of learning and imagination! Natsuki's advice was indeed right!"
Sasuke silently memorized these words again. These were the guiding lights on his path to becoming stronger.
Kakashi and the other two also praised this ingenious idea. Then Asuma Sarutobi and Kurenai Yuhi took their leave. They walked away side by side, their shoulders very close, seeming quite intimate. For a moment, Kakashi couldn't help but feel envious.
However, he was clearly more concerned about his student's state now.
He still couldn't help but ask: "Sasuke, you... didn't you think about going with Natsuki to chase them?"
Sasuke froze for a moment, silently clenched his fists, and only shook his head after taking a deep breath: "It's meaningless for me to go now! Natsuki told me to learn to be calm, and this is the result of my calm thinking! I need to become stronger first, and then I'll go find that person!"
"Is that so? That's good too!"
Kakashi let out a sigh of relief in his heart, feeling relieved by his student's growth.
He was really afraid that Sasuke would recklessly chase after Itachi Uchiha. That would be really troublesome. He didn't expect Sasuke to control himself, or rather, to learn to be calm, and this was all thanks to Natsuki.
"It seems you've learned a lot from Natsuki." Kakashi's eyes curved into a smile.
"Yes. I consulted Natsuki, and he taught me many useful things!"
Sasuke admitted frankly, but quickly changed the subject, "Kakashi... sensei, please teach me the fusion of Chakra Nature Transformation and Shape Transformation! It's those moves Natsuki used when fighting the tailed beasts. I want to create my own moves too!"
Kakashi was taken aback, then nodded with a serious expression: "Alright, after you've learned Chidori, it's time for this stage. However, this kind of training is very difficult. Can you handle it?"
Sasuke immediately became happy: "Of course I can handle it! Natsuki said that precisely because it's difficult, you'll become stronger after mastering it!"
"Mm! Very good! Excellent fighting spirit! Well then, today I need to formulate your training plan. Come to the training ground to find me tomorrow. The training will officially begin!"
"Yes! Kakashi... sensei!"
Meanwhile, Natsuki and Kai were traveling.
Along the way, Natsuki recounted the process of his previous battle with Itachi Uchiha and Kisame Hoshigaki to Kai, sharing information so that Kai wouldn't be caught off guard when they encountered enemies.
The two also discussed tactics, and their travel speed was not slow at all.
Fortunately, Jiraiya and Naruto did not conceal their whereabouts along the way, so it was not difficult to inquire about them, and they quickly located a small town.
Outside a certain small town, Naruto was practicing alone with an excited expression.
Although that Pervy Sage, Jiraiya, had gone off to have fun under the guise of gathering information, and had also lightened Naruto's frog wallet, Naruto didn't care at the moment.
Because the Pervy Sage had taught him the training method for the Rasengan.
Earlier at the competition venue, he had seen Natsuki's ultimate move, which seemed to be this Rasengan, but also seemed a little different. In short, this spiraling Chakra sphere had great power and was worth training diligently.
However, after not long into his training, Naruto became unhappy.
He had a boisterous personality. Training alone made him feel very lonely and boring, and he couldn't even muster the energy. He still wished someone could accompany him.
However, this was clearly a test, and Jiraiya would not accompany him.
If he couldn't even endure the loneliness of training alone, wanting to become stronger would be like a fool's dream.
Although Naruto was slow-minded, he roughly understood this principle. In order to become stronger, he could only force himself to train alone, striving to succeed quickly and make the Pervy Sage look at him with new eyes.
However, on this day, outside the town, he encountered two strange people wearing conical hats and black cloaks with red clouds.
