"As I said before, the difficulty is simple, this is just one of my statements, it does not represent the strength of the technique. Just like my disciple Uchiha Miku, she's a shinobi! But her strength is above me. Sasuke, you don't want to be bound by the inherent impression of ninjutsu. Remember, whether ninjutsu is strong or not always depends on the ninja itself, and ninjutsu itself is not strong or weak. To Sasuke's expectant look, Kakashi poured cold water on him.

"The power of ninjutsu...... Up to the ninja? Here, Sasuke thought about this sentence thoughtfully, and he suddenly asked back, "Kakashi-sensei, the strength of ninjutsu depends on the ninja, so what does the strength of the ninja depend on?" ”

Sasuke didn't know how he was supposed to get stronger, because he hadn't figured it out yet. Now, he asked the question.

"The power of the ninja...... It depends on the heart, and the strength of the heart depends on scientific thinking. Do you know what scientific thinking is? The so-called scientific thinking ......"

"The so-called scientific thinking is a theoretical system that forms and applies to scientific cognitive activities and the ways and means of processing perceptual cognitive materials; It is the organic integration of various scientific thinking methods in the process of the unity of truth understanding, and it is the product of human practical activities. Taking Kakashi's words, Sasuke memorized the knowledge from the textbook.

"That's a good study!" Seeing that Sasuke memorized the knowledge in the textbook, Kakashi praised him.

"It's nothing, it's just scientific thinking...... I thought that the strength of the heart would depend on perseverance, love, and so on. Speaking of which, Sasuke remembered Naruto.

"I'm not saying that feelings like perseverance and love aren't important, it's just that things like perseverance and love are slightly less important than scientific thinking. Why? Why is scientific thinking so important? In fact, before the Third Ninja War, no one would agree with this statement. ”

"Why?" Sasuke was stunned for a moment when he heard this, and he asked.

"Before the Third Ninja War, the communication between ninjas was not particularly frequent, and the ninjas at that time had very little communication with ninjas. More often than not, the ninja himself resonates with reality through constant tasks to generate realization. This realization carries a strong subjective view. At the same time, it is also the foundation of traditional ninja. ”

"The strength of the mind lies in the perceptual thinking, which was the mainstream before the Third Ninja War. Nowadays, the strength of the mind lies in rational thinking, that is, scientific thinking, which occupies the mainstream. The reason why this statement has become mainstream is the recognition that ninjas have exchanged their blood for defending the war. ”

“…… What is the difficult thunderstorm? Recovering from the solemn topic of the Third Shinobi War, Sasuke asked Kakashi.

"Speaking of difficult thunder escapes, we must first talk about simple thunder escapes. The so-called simple thunder escape is a thunder escape technique that relies on chaotic thinking such as perceptual thinking as the main body. In short, by feeling! And the difficult thunder escape, it does the opposite, using scientific thinking such as rational thinking to control the thunder chakra. ”

"Like this......" Kakashi said, snapping his fingers, and all the metal items in his ninja bag flew out.

"Come on! Try to take it away! Kunai was suspended in mid-air, and Kakashi got one of them in front of Sasuke and said to him.

"Take it?" Sasuke's doubts were written on his face, and he obeyed Kakashi's order and grabbed the kunai in mid-air, wanting to take it.

However, the kunai seemed to be fixed in mid-air, and no matter how hard Sasuke tried, the kunai just couldn't move.

"Do you know why you can't move? Perceptual thinking, thinking about the same, the result will be much worse. And rational thinking, thinking can't be bad, and the result is not bad. Speaking of which, Kakashi explained what he had just done.

"Actually, from the moment I asked you to hold the kunai, you couldn't have taken the kunai. Why? The moment you grasped the kunai, I got the friction between you and the kunai through the kunai chakra. No matter how your information changes, as long as I know it, I can create an opposing force to counteract your power. And this is where rational thinking is most powerful...... Compute! ”

"Calculations?"

"The essence of scientific ninja is to mechanize chakra through calculation. Your academic performance is very good, so you must have reached a certain level of understanding of scientific ninja. ”

"Is it?" Hearing Kakashi say this, Sasuke seemed to understand something.

"That's right! If you want to learn the difficult thunderbolt, you have to keep learning about electromagnetism. It's not just about learning, you have to learn to use it. Do you know why the alliance gave up the traditional ninja and devoted itself to the scientific ninja? ”

"Thunder Escape-Royal Thunder True Sword Flow!" With a soft snort, Kakashi's right hand gestured like a sword finger as he pointed at the remaining three walls.

The next moment, the kunai hovering above Kakashi's head all found their way, and in an instant, they were endowed with great power, shooting like sniper bullets towards the location of the earthen wall.

In a matter of seconds, three earthen walls were blasted to pieces.

"With an attack of this intensity, even if it is twice as fast and hundreds of times larger, I can hold on for a day. However, if it was Rachel, I would only have used it eight or nine times and the chakra would have dried up. ”

"Is this the power of scientific ninja!" Looking at the earthen wall that had turned into shards, Sasuke clearly felt the power of the Scientific Ninja for the first time.

"What about your choice?" After showing off the simple traditional Thunder Escape and the difficult Science Thunder Escape, Kakashi put the choice in front of Sasuke.

"I ...... I'm going to choose the easy one! Sasuke's thinking was quick, and he had already figured out the pros and cons of traditional and scientific ninja.

Traditional ninja relies on the sensibility of the soul and focuses on the state of mind and body. Scientific ninja relies on the rationality of the soul and focuses on accumulation.

The power of scientific ninja is more stable than that of traditional ninja, and it is also long-lasting. However, its power grows stronger with accumulation, and in terms of time, he has no chance. He chose traditional ninja path, not to give up scientific ninja. After this Zhongnin exam, no matter what the results were, he made up his mind and insisted on taking the path of scientific ninja.

"It's decided?" The corners of his mouth curled, and Kakashi asked as he looked at the boy in front of him.

"It's decided!" To be categorical, Sasuke is the one who will not give up after making a decision.

"Good! From now on, I'll explain you to the basics. And the most basic Lei Dun, you must first understand how the nature of Lei Dun should change! ”
