Early the next morning, Shinji woke up to the occasional birdsong outside his window.
He stretched, glanced at the system again to confirm it wasn't a hallucination from the previous day, then immediately got up to get ready for class. Even without the system, he had diligently trained, so there was no reason for him to be lazy now that he had a cheat.
After leaving his house, he was greeted by smiling residents and vendors along the way. After all, their children, more or less, were enrolled in the Academy, and Shinji's teaching methods were naturally very popular with the students. They would often mention him when they returned home, and naturally, these residents became familiar with Shinji.
Shinji nodded as he walked towards the Academy, not feeling bored at all along the way.
Arriving at the office, besides the teachers who had the first class today, there were only a few Chunin instructors present.
Shinji greeted them, then picked up the materials he had prepared the day before, ready to teach his students.
Standing outside the classroom, he couldn't help but smile, listening to the lively atmosphere inside. He pushed open the door, and the chatter in the classroom immediately ceased.
Shinji looked at the students, who were sitting neatly, and announced, "Class is starting!"
After speaking, he immediately spread out his lesson plan and picked up a piece of chalk to write Chakra on the blackboard.
Turning to look at the excited students, Shinji then began, "Chakra is the core energy source that we ninjas need when using Ninjutsu, Taijutsu, and Genjutsu. And its composition is formed by the combination of physical energy and spiritual energy."
Except for a small number of students from prominent clans, the rest of the students from ordinary families listened intently.
Even Naruto, who in the original story would get dizzy just hearing theoretical knowledge, was listening very seriously at this moment. After all, Shinji was someone who had acknowledged him, and Naruto didn't want to disappoint him.
As Shinji explained, occasionally releasing Chakra to give the students a clearer understanding and feeling, the classroom atmosphere was incredibly harmonious.
Even students from prominent clans like Sasuke and Shikamaru gradually put aside their dismissive attitudes and listened to the lesson. After all, when Shinji explained, he would also bring up some points they had never heard before.
Even for those who had received training early on, it was impossible for the clan to spend too much effort on a child who had not yet shown their potential.
As for their respective parents, that was just a fleeting thought. They were either clan heads or top Jonin, so where would they have so much time to teach them?
As time passed, Shinji stopped his lecture. He checked the time, there were still a few minutes left, so he decided not to continue teaching.
Balancing work and rest was a way to allow these students to fully absorb knowledge. He also gave them time for questions and then answered them one by one.
Even Naruto raised his hand once, and the point he brought up made Shinji slightly re-evaluate him. After all, if Naruto were truly a loser, he wouldn't be able to ask a question that made even some clan scions look at Shinji with an expression of understanding.
As the bell for class dismissal rang, Shinji stopped.
[Lesson completed, calculating...]
[Solid foundations earned the students' approval, giving them a clearer understanding of the basic concept of Chakra.]
[Overall Rating: A+]
[Reward: Chakra +1000]
Shinji was stunned to see another increase in his Chakra value.
His previous Chakra reserves could be said to be even less than Kakashi's, who often ran out of Chakra in the original story due to the burden of his Sharingan.
Two consecutive days of increases had caused his Chakra, which was once a small puddle, to surge into a small stream.

Looking at the Chakra amount on the panel, which was no longer a two-digit number, Shinji couldn't help but smile.
At this stage, even if he had Ninjutsu, he couldn't use it but Chakra was a tangible benefit.
As for the question of having a lot of Chakra but no Ninjutsu to make use of it, as long as he diligently taught and the students made progress, then for him, Ninjutsu and Genjutsu would come sooner or later.
Putting away his lesson materials, Shinji then said to the students in the classroom, "Everyone, class is dismissed. Eat well so you'll have energy for class this afternoon."
"Understood, sensei!"
From the tiered desks, each student responded to Shinji with strong, clear voices.
Hearing their response, Shinji smiled. He picked up his materials, and turned to walk out of the classroom door.
Before leaving, his gaze subtly swept over the two bugs that had flown in during class. Now seeing Shinji leave, they quickly followed him out.
'Heh. Danzo, you really can't stand being alone.'
Shinji didn't pay much attention. If they wanted to follow, let them follow. As long as he didn't do anything out of line, they would eventually give up. However, he needed to figure out a way.
Otherwise, if he wanted to take on disciples later, wouldn't everything be done right under Root's nose?
As Shinji pondered a solution on his way to the office, a voice interrupted his thoughts.
"Shinji, you're quite impressive. I happened to pass by your class earlier and took a look. Even some students from njnja clans were listening intently to your lecture."
Shinji turned to see Iruka, who was carrying a stack of lesson materials.
He shook his head and said, "Not at all, I just explained points I noticed during my own training. Plus, this class of students is relatively obedient."
Iruka, hearing Shinji say this, naturally knew that he was being humble.
After all, they were all training, so why couldn't the others organize their knowledge and teach the students?
"Alright, if you keep this up, I'll tell the other teachers later." Iruka playfully patted Shinji's shoulder, sounding quite annoyed.
Shinji merely glanced at Iruka indifferently, offering no further explanation. If it weren't for Iruka paving the way for him, and out of respect for that connection, he would have immediately used a Konoha Taijutsu Secret Technique, "A Thousand Years of Death".
"Let's go. There's not much time for lunch break. We don't want to finish eating and then immediately have to go back to class."
With that, Shinji quickened his pace.
