Shinji, who had just left the classroom, suppressed his inner joy.
Chakra perception is not unique in the Ninja World, but what he received was the Second Hokage's unique Area Scanning Technique.
Using this Ninjutsu allows one to sense the number of enemies and their Chakra levels within a large range.
Many memories flooded his mind, all about Chakra perception.
In an instant, even without using the complete jutsu, Shinji could clearly sense the number of people throughout the entire Academy and theur Chakra levels.
'If it weren't for the First Hokage and Madara being too abnormal, the strength displayed by the Second Hokage alone would have absolutely dominated the Ninja World in that era.'
Shinji couldn't help but click his tongue, a proficient-level Ninjutsu was already so abnormal.
Sensing a familiar Chakra approaching, Shinji stopped studying the reward he had received.
"Shinji, how was the class?" Iruka, who walked up from behind, greeted him warmly.
Hearing Iruka's words, Shinji turned his head and replied with a smile, "It was alright, it's not the first time I've taught a class, after all."
Iruka nodded, walked forward, put his arm around Shinji's shoulder, and headed towards the office.
"That's good, I was worried that you might find it overwhelming leading a class for the first time."
Shinji used the momentum to walk towards the office, while relishing the situation he had just sensed in that instant.
Naruto's Chakra, as sensed, was like an oversized light bulb. Shinji compared his current Chakra level with Naruto's and instantly felt a bit inferior.
Shinji set a short-term goal for himself.
'It seems I need to study this thoroughly later, and see if I can take on disciples to quickly get stronger.'
As Shinji and Iruka entered the office, they found several other teachers already inside, chatting about this year's students.
Seeing the two of them enter, they quickly greeted them. However, most of the greetings were congratulations to Shinji for finally being able to lead his own class this year.
A man, about a generation older than Shinji and Iruka, said with a smile, "Shinji, you absolutely have to treat us tonight. You've been here less than two years and you're already leading your own class."
Shinji nodded and said, "No problem, Yamashi-sensei. Even if you didn't say anything, I would have invited everyone one by one later. Since everyone is here, let's go to the izakaya."
Hearing Shinji's words, Yamashi laughed even more happily, agreeing repeatedly.
Masaru, sitting next to Yamashi, said with a teasing expression, "Yamashi, did your wife take your petty cash? You're already making Shinji treat us right after school started."
Yamashi's face turned red, and he gesticulated wildly, telling Masaru not to talk nonsense.
Seeing Yamashi act like this, the teachers in the office all burst out laughing. Yamashi had just gotten married, and they had been invited to his wedding not long ago. However, they didn't expect that Yamashi, who had always been a big chauvinist, would be so tightly controlled after marriage.

Inside the Hokage Office.
The Third Hokage, Hiruzen, rested his chin on his hands, watching through the crystal ball as Shinji stood at the podium, answering Naruto's question about how to become Hokage.
It wasn't until Shinji finished his explanation that he picked up his pipe and lit it, a smile slowly forming at the corners of his lips as he exhaled smoke.
Shinji possesses Hokage-style thinking.
To be honest, when Naruto joined the Academy this year, Hiruzen had two candidates for the class teacher: Iruka and Shinji. It wasn't because they were excellent teachers, but because they were young. They didn't have the same hostility towards Nine-Tails as the older generation of teachers.
He had a talk with Iruka and Iruka clearly declined the opportunity.
As for why, it's because his parents died on the night of the Nine-Tails's rampage.
Although it couldn't be blamed on a child, Iruka clearly stated that even if he tried hard to convince himself not to care, he ultimately couldn't let it go.
He also suggested to the Third Hokage that Shinji should take the position, as they were similar in age, and Shinji's teaching performance was definitely better than his.
Subsequently, Hiruzen gave up on Iruka and began to assess Shinji. This assessment lasted half a year, and the Hokage's Anbu followed him for several months.
Fortunately, everything was under control, and Shinji's class today further confirmed to Hiruzen that his choice was correct.
'Perhaps, I can focus on nurturing him further.'
Thinking of this, Hiruzen ended his Telescope Jutsu.
He slowly exhaled a puff of smoke while looking at the documents on his desk, and then began to deal with them.

In the afternoon, as students gradually went home, Shinji checked the classroom and then walked out of the teaching building with Iruka.
He was going to treat everyone later, so he didn't plan to go home, intending to go directly to the izakaya to wait for his colleagues.
As for Iruka, he was a lone wolf like himself, so there was no reason for him to go back first.
Arriving at the playground, Iruka, who had been talking non-stop, quieted down, his gaze fixed on a swing not far away.
Shinji followed his gaze to the swing, where a figure with yellow hair and a white T-shirt was sitting with his head down.
Shinji said, "Iruka, you go wait for me at the school gate. That seems to be a student from my class."
Then, he walked straight over.
Iruka behind him responded after a long pause, "Okay."
The person sitting on the swing was, of course, Naruto, who had just started school today.
Shinji quickly came in front of Naruto, who had been lowering his head. Feeling the light dim, Naruto looked up. The slightly dazzling light of the setting sun made Naruto unconsciously squint his eyes, unable to see clearly who it was for a moment.
He shouted loudly, his tone very defiant, "Bastard! What? Do you want to fight me again?"
Shinji was initially surprised, as Naruto's clothes were clean during class in the morning, but now they were not only covered in dust but also had some holes.
Hearing Naruto's words, he realized that he had been fighting. However, looking at Naruto's condition, it was more likely that he had been beaten.
"Naruto, are you hurt?" Shinji squatted down, a gentle smile on his face, and asked in a very mild tone.
Naruto, who had been looking stubborn, heard the voice and finally opened his eyes to see who it was. A strange emotion lingered in his chest. Then, tears slowly rolled down from the corners of his eyes, and he looked at Shinji with a very wronged expression.
"Ahhhhh... sensei!"
Iruka, who had just reached the school gate, heard the crying. His pupils constricted, and the expression on his face was unclear.
Shinji looked at Naruto, who was crying uncontrollably, and remained motionless for a long time. It wasn't until Naruto stopped crying that he squatted down, his eyes fixed on Naruto's red, tear-stained eyes.
