Believing in books too much is worse than having no books

Uchiha Kō and Tsunade returned to the villa, both in good spirits, especially Tsunade, who hugged Uchiha Kō and chuckled.

"Thank you, honey~. I reckon among all the Hokage, you're probably the only one who spoke up for those rural women!" Tsunade said earnestly.

Uchiha Kō chuckled wickedly, "So, how are you going to thank me, my wife?"

Tsunade blushed. "Hmph, I'm going to take a bath!"

Uchiha Kō was stunned. No? This isn't what I wanted! Hey! His lips twitched, but he couldn't fight city hall. He sighed and went to take a shower too.

After the two finished washing, for a long time

The next morning, a ray of sunlight streamed through the window. Uchiha Kō, sporting Black Eye under his eyes, got out of bed. Who was he? Where was he? What did he want?

He glanced at his phone one last time at the message notifications; it was his teaching day. He quickly got up, made breakfast, and then called out into the house, "Honey, I'm off to work! Breakfast's on the table, remember to eat!"

After saying that, he picked up a sandwich, took two bites, and then snapped his fingers, "Flying Thunder God Technique!"

In an instant, Uchiha Kō appeared in the classroom. He glanced at the clock on the wall and realized that he was not late; in fact, he had arrived ten minutes early. He nodded in satisfaction.

"Thank goodness I'm not late! But why does the floor feel so soft?" Uchiha Kō wondered, when a voice came from behind him, "Ouch, teacher, could you... could you get off me?"

Namikaze Minato's voice rang out. He was just erasing the blackboard when Uchiha Kō suddenly appeared, right above him. This surprised him. It seemed that there was no such ninjutsu in Konoha, at least he had never seen it before.

Uchiha Kō was a little embarrassed. He had set the coordinates of the Flying Thunder God Technique above the blackboard, but he didn't expect that someone would come to the classroom early to erase the blackboard today. It was Minato Namikaze, the Little Sun Namikaze Minato.

Uchiha Kō quickly danced a few steps, then awkwardly extended his hand to Namikaze Minato, saying with a forced smile, "Won't you stay long!"

Namikaze Minato grasped Uchiha Kō's hand, stood up, and exhaled. Instead of immediately focusing on his pain, he asked, "Sensei, what kind of ninjutsu is that? It can even traverse space!"

The ninjutsu in Uchiha Kō's hands was so powerful that, in his opinion, it was simply incredible.

Looking at Minato's starry eyes, Uchiha Kō couldn't help but scratch his head. "This technique is called the Flying Thunder God Technique. It's Space-Time Ninjutsu created by the Second Hokage, Senju Tobirama. It's not that I didn't want to teach it to you, but with your current chakra reserves, the practical effect of Flying Thunder God Technique isn't even as fast as using the Body Flicker Technique!"

"Furthermore, excessive chakra extraction at a young age can overload the body, shorten lifespan, and cause various illnesses," Uchiha Kō patiently explained to Namikaze Minato.

Namikaze Minato was taken aback. "Is this true? I've never heard of the idea that extracting more chakra as a child would harm one's health! On the contrary, everyone thinks that the more chakra extracted as a child, the stronger one's talent!"

Uchiha Kō patted his head. "That's a misconception. Just remember, cultivation is a gradual process. If you want your body to hold more chakra, then strengthen your muscles. Only when your physique improves should you extract chakra, so as not to put a burden on your body."

Namikaze Minato nodded, keeping Uchiha Kō's words in mind. He firmly believed that his teacher, the Fourth Hokage, Uchiha Kō, would never harm him!

At the same time, I secretly redoubled my efforts, determined not to neglect my physical training in the future. Although this world is one of high offense and low defense, a strong physique can truly help you survive in various dangerous situations and even unleash amazing potential.

Seeing that Minato Namikaze had taken his words to heart, Uchiha Kō Namikaze Minato nodded. "Alright, go back to your seat. Oh, by the way, the blackboard is very clean, thank you, Minato." Uchiha Kō smiled and patted Namikaze Minato's blond hair.

Namikaze Minato chuckled, and after Uchiha Kō finished touching him, he returned to his seat, took out his books, and continued reviewing the knowledge he had learned before setting off.

After seeing Namikaze Minato return to his seat, Uchiha Kō also got up and left. Danzo's teaching time was in the morning, and he would train the six little ones in the afternoon.

And so, all morning, the voice of Shimura Danzō teaching echoed throughout S Class, with students occasionally asking and answering questions, creating a scene of teacher-student harmony.

Uchiha Kō listened to Shimura Danzō's lecture in the corridor and couldn't help but nod. At first, Shimura Danzō just read from the book and there was very little interaction between the teacher and the students. But now, he not only interacted with the students, but also let them think for themselves, instead of just teaching the knowledge in the book.

This is important and necessary. Blindly believing everything in books is worse than having no books at all. Some things are too one-sided or too idealistic to rely solely on information from books.

Especially history, history is always written by the victors, and the world has always been a time of great strife. Whoever has the biggest fist, whoever wins in the end, can decide the fate of history.

It wasn't until noon, when the school bell rang, that Shimura Danzō away his books and said, "I hope you kids will think carefully about what I've discussed today. If you were just ordinary disciples, I wouldn't have said these things, but you are the Lord Hokage's disciples, the future of Konoha. These are things you must study and understand."

"Class dismissed!" Shimura Danzō said, picked up his lesson plan, and pushed open the classroom door to leave.

The six children breathed a sigh of relief. They felt completely overwhelmed. Today's lesson made them realize that what is written in books is not necessarily true, but it can be used as a reference and studied carefully.

As soon as Shimura Danzō outside, he saw Uchiha Kō. He was taken aback at first, then saw Uchiha Kō give him a thumbs up. "Hehe, Danzo, I didn't expect you to teach so well! Blindly believing everything in books is worse than having no books at all. This is the most important lesson the kids learned!"

Shimura Danzō's eyes softened as he said, "If they were just ordinary ninjas, or if they weren't your disciples, I wouldn't want them to know these things. The more you know, the more you'll know, and sometimes, knowing too much isn't a good thing."

Uchiha Kō nodded. "You're right, but they are my disciples, and they'll have to know these things sooner or later. I think it's the right choice for Danzo to gradually change them."

The two looked at each other, then burst into laughter and went to eat a boxed lunch together.
