Ryun and Tsunade returned to the villa. Both were in a good mood, especially Tsunade. She hugged Ryun and grinned.
"Thank you, husband. Probably among all the Hokage throughout history, you are the only one willing to speak up for those women in the villages!" Tsunade said seriously.
Ryun chuckled. "Then how do you plan to thank me, wife!"
Tsunade's face turned red. "Hmph, I'm going to take a bath!"
Ryun was dumbfounded. Wait, that's not what I wanted! Hey! The corner of his mouth twitched, but you can't fight city hall. He sighed and also went to take a bath.
After both had finished bathing, a long time passed...
The next morning, a ray of sunlight shone through the window. Ryun got up with dark circles under his eyes. Who was he? Where was he? What did he want to do?
Finally, he glanced at his phone's message reminder. Today was a teaching day. He quickly got up, prepared breakfast, then called towards the room, "Wife, I'm going to work! Breakfast is on the table, remember to eat!"
After saying that, he picked up a sandwich, took a couple of bites, then snapped his fingers. "Flying Thunder God Technique!"
In an instant, Ryun's figure appeared in the classroom. He looked at the clock on the wall and found he wasn't late; instead, he had arrived ten minutes early. He nodded in satisfaction.
"Good, not late. But why does the floor feel soft?" Ryun was puzzled. Then a voice sounded, "Ouch, teacher, can you, can you get off me?"
It was Minato's voice. He was just cleaning the blackboard when Ryun suddenly appeared, right above him. This surprised him; it seemed there was no such jutsu in Konoha, at least he hadn't seen it.
Ryun felt a bit awkward. He had set the Flying Thunder God marker above the blackboard, but didn't expect someone to come to clean the blackboard early today, and it was the little sun, Minato.
Ryun quickly jumped down. He reached out his hand to Minato and laughed awkwardly, "Sorry about that!"
Minato grabbed Ryun's hand and stood up. He let out a breath, not focusing on his own pain first, but instead asking, "Teacher, what kind of jutsu is this? It can actually traverse space!"
The jutsu in Ryun's hands was so powerful. In his view, this was simply too cool.
Seeing the stars in Minato's eyes, Ryun couldn't help but scratch his head. "This technique is called the Flying Thunder God Technique. It is a space-time ninjutsu created by the Second Hokage, Tobirama Senju. It's not that teacher doesn't want to teach it to you, but because your current chakra level means the practical effect of using the Flying Thunder God Technique wouldn't even be faster than using the Body Flicker Technique!"
"Moreover, extracting too much chakra at a young age can cause the body to become overloaded, reduce lifespan, and lead to illness." Ryun explained very patiently to Minato.
Minato was stunned. "Is that true? I've never heard that extracting more chakra when young could affect health! On the contrary, everyone thinks that extracting more chakra when young means stronger talent!"
Ryun patted his head. "That understanding is wrong. Just remember, training should be step-by-step. If you want your body to hold more chakra, then strengthen your physical muscles. Only when your physique improves, then extract chakra, will it not put a load on your body."
Minato nodded. He committed Ryun's words to memory. He firmly believed that his teacher, the Fourth Hokage, Ryun, would absolutely not harm him!
At the same time, he secretly resolved to work harder; he couldn't neglect physical training in the future. Although this world was one of high attack and low defense, a strong physical body could really save your life in various dangerous situations, and even unleash astonishing potential.
Seeing that Minato had taken his words to heart, Ryun nodded. "Alright, go back to your seat. Oh, and the blackboard is cleaned very well, thank you, Minato." Ryun smiled and ruffled Minato's blond hair.
Minato also grinned. After Ryun finished, he returned to his seat, took out his book, and continued reviewing the knowledge he had learned before setting out.
After seeing Minato return to his seat, Ryun also got up and went out. The morning was Danzo's teaching time; he would take the six kids for training in the afternoon.
And so, for the entire morning, the S-class classroom echoed with the sound of Danzo teaching. Occasionally, students would ask questions and get answers, a scene of harmonious teacher-student respect.
Ryun listened to Danzo's lecture from the corridor and couldn't help but nod. Initially, Danzo just read from the book verbatim, with little interaction between teacher and students. But now, he not only interacted with students but also encouraged them to think for themselves, not just relying on the textbook knowledge.
This was very important and necessary. Blind faith in books is worse than no books. Some things, if only learned from books, are too one-sided, or perhaps too idealized.
Especially history. History is always written by the victors. The world has always been one of great contention. Whoever has the biggest fists, whoever wins in the end, gets to decide the narrative of history.
Finally, at noon, the school bell rang. Danzo closed his book and said, "What we discussed today, I hope you kids will think about carefully when you go back. If you were just ordinary students, I wouldn't say these things. But you are the Hokage's students, the future of Konoha. These are things you must study and understand."
"Class dismissed!" After saying that, Danzo picked up his teaching materials, pushed the classroom door open, and left.
The six kids all breathed a sigh of relief. They felt their heads were spinning. Today's lesson made them realize that what is written in books isn't necessarily true, but it can be used as a reference for careful study.
As soon as Danzo stepped out, he saw Ryun. He was startled at first, then saw Ryun give him a thumbs up. "Heh, Danzo, I didn't expect you to teach quite well! 'Blind faith in books is worse than no books'—that phrase is the most important takeaway for the kids from this class!"
Danzo's eyes softened. "If they were just ordinary shinobi, or if they weren't your students, I wouldn't want them to know these things. Because the more you understand, the more you know. And sometimes, knowing too much isn't a good thing."
Ryun nodded. "You're right. But they are my students. They will have to know these things sooner or later. I think having you, Danzo, slowly change their perspective is the most correct choice."
The two looked at each other, then laughed heartily together, and went to eat a boxed lunch.
