"Teacher Obito, tell me about it! How can I have the power of the ninja I saw before! Here, Naruto didn't seem satisfied, and he asked Obito again.

"Haven't I said it many times? As long as you work hard to learn mathematics, physics and chemistry, coupled with diligent cultivation, you can become a powerful ninja. The old tune was repeated, and Obito said helplessly.

"But...... But my theory is so bad! Naruto asked with a wistful face, "Obito-sensei, do you have anything to ...... Shortcut? ”

"A shortcut?" Obito was stunned for a moment, and he began to think seriously. Here, listening to the conversation between the two, Sakura and Sasuke also pricked up their ears.

"I don't have a shortcut, but I have a way." Spreading his hands, Obito said to Naruto, "This person is like a leaf on a big tree, and no leaf is the same. The same method may be useful for Naruto. However, when it comes to Sakura and Sasuke, it doesn't apply. ”

"We've been together for a few months, and I've got some insight into your practices. Science is to maximize the benefits of reality from a materialist point of view. Naruto's theory is not strong, so put more effort into practice. Sakura, on the other hand, has a limited number of exercises, so she is more theoretical. As for Sasuke, I think it's good to have a good balance of time between theory and practice. ”

"Is that all? That's what I usually do! After thinking about it, Naruto said puzzledly, "I don't feel like I've made a lot of progress in my usual life. ”

"You're not doing it right!" Obito repudiated Naruto's words, he shook his head and said, "Think about it, have you really reached the limit of your practice?" ”

"Uh......" Naruto hesitated a little about this question.

"Naruto, I know you've learned the art of multiple shadow clones. What I'm trying to say is that this is a difficult A-level ninjutsu, and you have developed too little of this technique. ”

"Development?" Naruto was stunned for a moment, and he muttered.

"The same technique, treating different things, will produce different results. In your eyes, the technique of multiple shadow clones may only be a technique used for combat, but some people like to use it for cultivation. ”

"The shadow clone is a physical clone, and what happens to the shadow clone can be known to the body after it is lifted. So, the essence of the shadow clone, you can understand it, is to get information. And the information of the battle is only one kind of information. Use the shadow clone to practice physical arts, use the shadow clone to practice illusion, and use the shadow clone to practice ninjutsu. With your chakra size, this technique can exert unimaginable power. ”

“…… I understand! As Obito spoke more and more, Naruto's eyes began to brighten up. Eventually, with a cheer, Naruto jumped for joy.

"Teacher, teacher! What about me? Seeing that Naruto had gained a lot, Sakura also wanted to get some advice from Obito.

"Sakura-chan?" Here, Obito glanced at Sakura, and he said, "In terms of controlling Chakra's talent, Sakura should be the most talented among us." ”

"You have just become a shinobi, and everyone has seen the previous battle, you are undoubtedly weak. The weak, on the other hand, is to play to their strengths to cover their weaknesses. Sakura's chakra is very controllable, and her attribute is water. So, Sakura, you can try to control the flow of water. ”

"Flow rate?" Sakura was stunned for a moment, and she asked, "Why the flow rate?" ”

"The teacher has been studying at the headquarters of the Alliance before becoming your teacher. O the people in there! All of them are talented, and they speak well, and I love the ...... in it."

"Far away! I would like to say that at the headquarters, I met a ninja who specializes in fire escape. The ninja said something that impressed me. Do you know what that is? He said: According to mathematical calculations, none of the fire ninjas in the ninja world can actually be called fire ninjas. ”

"Why?" Here, Sasuke asked with a frown.

"Because, according to his calculations, among the ninjas in the ninja world, the ninjas who use fire escape, they only exert less than ten percent of Chakra's thermal energy. If a ninja can perfectly exert the energy of the chakra, then his strength can increase from ten times to dozens of times in an instant. ”

"Come to think of it, a shinobi like me, through hard cultivation, has only exerted ten percent of the chakra power."

"Mr. Obito, I don't really understand the flow rate you said, can you be more specific?" Sakura asked.

"Yes!" Nodding, Obito said, "The macrocosm is made up of countless microcosms, and the microcosm is not a world, it is a plural world composed of several magnitudes. Micro and macro, are relative.

Now, to use an analogy, my limit is to control the flow of water that is the thickness of my thumb. If the water with a thumb is the size of my thumb and I break through the limit and become a flow with a little thumb. Then, with the same force, the speed of the water flow will speed up several times. Although the overall strength did not increase, the pressure of the water increased. ”

"The same way! The thinner the current, the faster it goes. When the flow of water is thinner than a human hair, then the water cannot be called water. It has to be called a water jet, and this water jet is sharper than a steel knife. The strength has not changed, but the effect has changed amazingly, which is because of the increased efficiency of the water escape. ”

"I see! What about the specific cultivation methods? Sakura asked again.

"You can only think of the specific method yourself, the teacher has not practiced Shui Dun, so he can only give you such a general idea." Spread his hands, Obito said helplessly.

“…… All right! With a sigh, Sakura began to think about her cultivation method on her own.

"What should I do?" Naruto's path is clear, Sakura's path is clear, and now Sasuke doesn't know how he should develop. To this, he asked Obito.

"Sasuke's words......" Here, just as Obito was looking at Sasuke and thinking about what to say, a rapid sound of breaking the air attacked Obito.

At this point, Obito reacted immediately, and he pushed his left hand to the side and pushed Dazna away. At the same time, his right hand flicked, and a bitter hair was thrown from the cuff to the palm of his hand.

"Dang!" A dull metal clash sounded, and Obito used kunai to unblock a large knife that was spinning.

After that, because of the stampede technique, Obito didn't move much in place. The big knife, on the other hand, was blocked, flew back, and stuck in the ground.

The next moment, a man with short black hair standing almost shirtless stood on the hilt of a large knife.
