After the three of them had lunch and everything was cleaned up, Mizuki stopped Haruno Sakura and asked, "Have you read all the materials that I gave you?"

"It's over, Mr. Mizuki." The teaching is finally about to start, and Sakura is looking forward to it.

"That~" Yamanaka Ino said tentatively, "Should I avoid it?" After all, it is not a good thing to spy on the secrets of other ninjas casually.

Mizuki glanced at Ino and said casually, "No, you don't understand anyway."

Ino was speechless for the choked sentence. Earlier, Ino also took a peek at what Sakura had learned. It was all a pile of celestial books like ghosts and talismans, and he had no idea what it was talking about.

"I've read it, but I can't understand most of it." Sakura replied.

"It doesn't matter if you don't understand now, I will teach you slowly next." Shuimu paused and then asked: "First of all, what I want to ask is, what do you think chakra is?"

"Chakra?" Haruno Sakura wondered, isn't this the basic course of the ninja school? Why did you ask this, but Sakura answered quite well, "It is the energy that is extracted from the body and mind after the human body controls the body and the spirit, and is the energy produced by the perfect fusion of the two. Base."

Mizuki nodded and said, "You're right, I remember the knowledge of the ninja school very clearly, but this standard answer doesn't really explain the essential problem."

"How? Is it wrong?"

"You're right, but you only told me how chakra came from, and what is the use of ninjas in general, but the more important things are not clearly explained, like the sunlight outside, we all know it comes from The sun can promote the growth of plants and bring warmth to people, but few people clearly explain what sunlight is and how it works.”

The words made Haruno Yingrao's head dizzy. After thinking about it carefully, he still had no clue. He couldn't help but say, "I don't know, Mr. Mizuki, I've never thought about this kind of question before."

"If you want to make a difference in the future, you still need to think more about these issues."

"Yes, please ask the teacher for advice." Sakura asked modestly.

"What exactly is chakra? This question must have been studied by many people, and each has their own views, but in my opinion, chakra is a bridge between the soul and reality of ninjas."

"Soul connection to reality?" Sakura asked suspiciously, this statement had never been heard before.

"Yes, chakra is the energy formed by the combination of cells and spirit in the body. It is an excellent carrier of personal will. It is an excellent reflection of dreams into reality." Speaking of this, Mizuki asked, "You never thought about it. Why can ninjas do things that many ordinary people can't do or even dare to think about?"

"Because ninjas have chakras~" Sakura replied subconsciously.

"Yes," Mizuki nodded affirmatively, "As a ninja, most people will subconsciously ignore this thing that builds the foundation of the ninja world."

"It's not surprising because it's commonplace."

"Actually, it's no wonder. You must know that the ninja world is not peaceful, and due to the pressure of survival, not many ninjas will consider this aspect; there is another situation that there is no need to think about it at all. Some people...for example, have Sasuke Sharinyan, the talented Naruto and Gaara, they only need to consider how to use their innate advantages, Chunin and Jōnin are no problem, they have a great chance to become the shadows of the five major ninja villages. ."

"Forget Sasuke, is Naruto so strong?"

"You'll find out later," Mizuki didn't answer directly, "so what I want to say is that they don't have to understand what I'm going to teach you, they won't learn it anyway, and it's the right way to use their strengths. One type of person only needs to be properly taught and then instinctively use chakra to perform ninjutsu."

Speaking of which, the smart Sakura understood something: "Mr. Mizuki means that if I want to keep up with their footsteps, I have to learn more fundamental things?"

"Yes, you don't have their innate advantages, but you have a smart mind that they can't keep up with. Maybe someone can teach you some more magical and more suitable ninjutsu to strengthen your strength, but I can't do it. Mizuki said bluntly, "So, follow me, you must understand the knowledge that only ninjas with high IQ can understand. However, first of all you have to learn this~"

Saying that, Mizuki stretched out his left hand, ran Chakra, a light blue light wrapped his palm, and then waved forward, a sharp blade flashed, and the chilling breath surprised Haruno Sakura who was standing beside him.

Mizuki also nodded with satisfaction. Since his return from the Land of Waves, he has made great progress in medical ninjutsu, which was not very good. The chakra scalpel is already proficient. It looks like the mutated spells that have been sacrificed for a lot of vitality are still somewhat useful.

"Did you see clearly?" Mizuki said to Haruno Sakura who was beside him: "Ninja fighting with ninja gear is the basis, but for ninjas with excellent control, sometimes there is a better choice. This is called a chakra scalpel."

"Chakra scalpel?" Sakura asked in confusion, "Is it medical ninjutsu?"

"Yes, when you learn this, I will teach you more practical palm immortality techniques. Sometimes, medical ninjutsu can not only be used to save people, in fact, when it comes to killing people, there are really few more skilled than medical ninjas. already."

After finishing speaking, Mizuki took out the scrolls that recorded the Chakra scalpel and palm immortality and handed it to Haruno Sakura.

"This is for you first, and you can practice at home."

Sakura took it and put it away.

"By the way, what is your chakra attribute?"

"Water and Earth."

"Is the flexibility of water and the thickness of soil? No wonder Tsunade was taught to be a violent medical ninja with strange powers. 』

"Then let's do it for now. It's question time. What do you want to say?"

"Mr. Shuimu, what have you shown me these days? I probably know the knowledge of sealing techniques and some spells, but these are much more than what I knew before, and they are more difficult than decrypting passwords. What are these things? "

Hearing Sakura's question, Mizuki thought for a moment and then said as plainly as possible: "It is more appropriate to think of it as a knotting technique on paper. Dozens of knotting combinations can be used in thousands of ways. There are thousands of ninjutsu, and most of the functions of the runes I gave you were verified by me. Although they cannot be guaranteed to be perfect, they can give you a foundation for understanding and enable you to get started. Combinations can form countless sealing techniques with different functions, formations, enchantments, charms, etc. It is the basic tool for in-depth understanding of more ninjutsu in the future."
