12: The School Teacher Can’t Teach Him Anymore
Iruka: "..."
He was feeling miserable in another world.
He had completely lost his self-confidence after being outclassed by an overly talented student.
Hatake Kakashi: "With Sasuke's strength, he could almost take the Chūnin exams."
What he lacks in physical strength and chakra, he makes up for with his Sharingan, ninjutsu, and genjutsu.
Rock Lee: "But Sasuke is only 7 years old... Can he take the Chūnin exams now?"
Might Guy: "Lee! Kakashi became a Chūnin at the age of 6!"
Rock Lee: "So that's what it means to be a genius!"
Might Guy: "As long as you work hard, you can catch up with geniuses!"

[Iruka, sweating profusely, didn't know what to teach.]
[As a Chūnin teacher, it was embarrassing to have nothing left to offer a ninja academy student.]
[Suddenly, Iruka thought of something:]
"I'll teach you a high-speed body movement technique called the Body Flicker Technique!"
"The Body Flicker Technique involves gathering a large amount of chakra at the soles of your feet and releasing it explosively, allowing you to move so fast that it appears like teleportation."
"However, it requires very precise chakra control in the feet."
[Sasuke listened carefully, absorbing the key points of Iruka's explanation.]
[Then, he began practicing the Body Flicker Technique.]
---
Shiranui Genma: "The Body Flicker Technique? Isn't that something that only Special Jōnin can usually master?"
Ebisu: "Well, as a Chūnin, Iruka could learn it too... but I wonder if he has mastered it himself."
Iruka: "Ahem... That was the Iruka from another world. It has nothing to do with me."
It was terribly embarrassing.
He hadn't mastered the Body Flicker Technique yet.
And the timeline shown on the screen was from five years ago in another world.
That Iruka had actually taught Sasuke a technique he hadn't mastered himself.
Still, what else could he have taught? He had run out of options.
Onoki: "Interesting. If I try to teach a technique I haven't mastered, could someone still learn it?"
Fourth Raikage: "If Uchiha Sasuke learns it this way, he truly is a genius!"
Orochimaru: "I have great confidence in Sasuke."
---
[Sasuke continued practicing the Body Flicker Technique.]
[Oddly enough, unlike previous techniques, Sasuke struggled with this one.]
[He felt something was missing in Iruka's instructions.]
[After days of no progress, Sasuke returned to Iruka for further guidance.]
[But it was clear that Iruka had nothing new to offer.]
[Sasuke noticed that Iruka seemed a bit evasive, but couldn't understand why.]
[Back at home, Sasuke resumed his training, thinking hard about what was going wrong.]
[He worked through trial and error, analyzing problems, making guesses, and testing solutions.]
[Gradually, his control over the Body Flicker Technique improved.]
[A month later.]
[Sasuke demonstrated the Body Flicker Technique in front of Iruka.]
---
Iruka's face froze.
Uzumaki Naruto: "Hahaha! Iruka-sensei's face is priceless!"
Uchiha Sasuke: "Naruto, are you seriously focused on that right now?!"
Hyuga Neji: "He actually mastered it…"
Iruka: "I'm starting to suspect Sasuke from that other world is cheating…"
Iruka could now fully empathize with the other-world version of himself.
Pretending to master the Body Flicker Technique that he hadn't learned, only to have his student actually master it. What a joke!
Orochimaru: "There's no doubt that Sasuke from the other world is a true genius in every sense."
Namikaze Minato: "His ability to learn and think independently is impressive. He can fill in gaps in his knowledge and improve through incomplete information. He's already on the path to developing his own jutsu."
The entire ninja world was stunned!
Developing his own jutsu!
Those who could do this were destined to be Jōnin or even greater!
Throughout ninja history, only the most powerful shinobi—those who left a lasting legacy were capable of such feats.
And here was Uchiha Sasuke, a 7-year-old academy student from another world, already reaching that level!
No one doubted Namikaze Minato's judgment.
After all, he was the one who had developed the A-rank Rasengan!

[After a while, Iruka snapped out of his shock.]
[Faced with Sasuke's desire for more guidance, Iruka confessed the truth.]
[The Body Flicker Technique he had taught Sasuke—he himself hadn't mastered it.]
[Furthermore, he had nothing else left to teach Sasuke.]
[All the teachers at the academy were Chūnin, just like him.]
[In other words, there was nothing left that the academy could offer Sasuke.]
[Sasuke would have to wait until he graduated to receive training from a Jōnin.]
[But since the village was in a time of peace, students were no longer allowed to graduate early.]
"As for future training," Iruka said honestly, "I only know that Jōnin must master various chakra nature transformations."
"But I don't know how to teach that."
[Sasuke didn't get the answer he wanted, but he still thanked Iruka for his help.]
[From now on, Sasuke realized he would have to figure out his own training.]

Today things will work a bit differently. Instead of 20 power stones, if the book gets more than 10 reviews before the end of the day, I'll add an extra chapter (I know, I know... even Albert Einstein couldn't match my cunning and wit). 🤓
P.S.: But if both goals are met (+20 stones and +10 reviews), I'll add 3 extra chapters!🔥
