At two o'clock in the afternoon, Naruto, Sasuke, and Sakura arrived in the promised woods on time, and unsurprisingly did not see Kakashi.

"Kakashi-sensei is late again..."Naruto said with his hands folded behind his head and a helpless expression.

"Then wait!Sasuke, do you want to sit in the shade of the tree!" Sakura immediately leaned to the second pillar and asked with a nymphomaniac expression. The second pillar was too lazy to pay attention to Sakura, he found a random tree, leaned on the trunk and closed his eyes to recuperate.

"Cut!" Naruto walked over to Sasuke and sat on the grass pulling at the blades of grass boredly.

The three of them waited for nearly half an hour before Kakashi walked slowly on crutches. The three children immediately ran to him, and when they saw Naruto wanting to speak, Kakashi stretched out his hand to stop him, "Since everyone is here, then let's not waste time and start cultivating!"

'It's obvious that you're wasting your time!' Naruto, Sasuke, and Sakura all three children roared inwardly at the same time.

As if he hadn't seen the disgusted expressions of the three children, Kakashi said with a smile, "But before I begin, let me reiterate that ninjas are basically 'chakra'!"

"It's time for it, it's still ......" Sasuke crossed his waist with one hand, looking helpless.

"Of course I know that kind of thing, it's Cha Bula, right?" Naruto said with a grin.

"It's Chakra... Sakura. Kakashi corrected Naruto with a bit of a headache, and after thinking about it, he even got the name of Chakra wrong, which means that Naruto, a child, didn't listen to classes at all when he was in school before! So he asked Sakura to give Naruto a make-up lesson, and Sakura stood up with a serious face and said, "Naruto, listen up." Because this is complicated, I'll just briefly explain it. The so-called 'chakra' is a kind of energy that ninjas need when they use ninjutsu, and this energy is ...... lalala."

"That's right," Kakashi said in a surprised tone, "I didn't expect Iruka-sensei to teach such a good student!" Sakura smirked when she heard this.

"Really, whatever!" Naruto said with some confusion, "Even if you can't remember this complicated explanation, you can remember it with your body!"

"Naruto is right," Sasuke agreed with Naruto for a rare time, "and a few of us can already use ninjutsu." ”

"No," Kakashi said in a rare seriousness, "you haven't been fully skilled at manipulating Chakra. Listen, just like Sakura said just now, the so-called 'refining chakra' is to take out the energy of the body and mind and mix it. Depending on the ninjutsu, the amount of extraction is different, and the required blend will be different. Now you can't use chakra effectively, even if you extract a large amount of chakra, if you can't control the balance, not only will the effect of ninjutsu be greatly reduced, it may make ninjutsu unable to be activated, but also because of the waste of energy, resulting in a weakness that cannot fight for a long time. ”

Naruto didn't expect there to be so many disadvantages, and he asked seriously, "So, what should I do?" he asked, laughing embarrassedly to himself.

Kakashi was silent for a moment before he said in an extremely serious and serious tone, "Use your body to remember the method of control, this is a difficult cultivation that can only be completed by risking your life!" Suddenly, the three children were stunned by his bluff.

"That's... So what are you going to do?" Sakura asked, swallowing her saliva.

Kakashi held out a finger and pointed to the shade above his head and said, "Climb the tree." ”

"Climbing a tree?!" the three children felt as if they had been deceived.

"But this is no ordinary tree climb, and it's not a hand climb. Kakashi said, his hands stamped, and he walked to a large tree on crutches, and walked vertically up to the surprised gaze of the three children.

Walking to the branch of the tree, Kakashi fell on it and looked at the three children and said, "That's probably it, concentrate the chakra on the soles of your feet and let your feet attach to the tree, as long as you use chakra, you can do it to this extent." How's that, it's easy!"

"Is the cultivation method controlled by Chakra similar to the bowl full of water on the top of the head taught by Sister Izumi. Sasuke listened to Kakashi's explanation and immediately understood.

"Izumi-san is so powerful!" Sakura sighed in surprise when she heard Sasuke's words.

"Hmph, that idiot is far off...... Sasuke turned his head disdainfully, but Sakura felt it, and Sasuke seemed to be happier.

Then, the three children began to practice, Sasuke had Izumi at home to give him a small lesson, and after only five times of practice, he could hang upside down on a branch like Kakashi, the difference was that he was not as relaxed as Kakashi, his muscles were tense, and he looked like he was ready to fall off in failure.

Naruto, the kid, refused to admit defeat, and he rushed to the tree again and again, stepping on the trunk a few times with all his strength, and then fell down with a "click". Sakura cautiously tried step by step, and when she was about to fail, she used kunai to cut a knife on the trunk. As mentioned in the original book, Sakura is very talented at the subtle manipulation of chakra, so as a beginner, after practicing for half an hour, she can walk on the branches like Sasuke, but she is much more stable than Sasuke. With such a talent, even Sasuke couldn't help but look at this pink-haired girl a few more times.

"It's amazing, it's Sakura-chan! However, I'm definitely not going to admit defeat!" Seeing that the two companions succeeded one after another, Naruto tried harder, and he rushed to the tree again and again, and fell down again and again. Kakashi leaned against a big tree not far away, looked at the three children's cultivation and said thoughtfully, "That's the difference between Naruto and Sasuke!"

"It's not just the perception of chakra, but also the control and maintenance are excellent. In this way, the closest person to the Hokage is Sakura! This is different from someone, and the Uchiha clan is not as powerful as expected!" Kakashi teased in a lazy tone, and Naruto and Sasuke were suddenly upset.

Sakura sat on a branch and pointed at Kakashi and shouted, "Sensei, you're so long-winded!"

Although Kakashi said this, he was more optimistic about Sasuke and Naruto in his heart, because these two people had too much chakra in their bodies than Sakura, and if their cultivation went well, it would become a huge wealth for the two.

"Okay, then the priority will catch up with Sasuke! Naruto's expression froze, and instead of his previous reckless approach, he walked to the tree, slowly and with difficulty, step by step.

Unbeknownst to the three children, in the shade of a tree not far away, an even younger boy stood there, watching them practice with calm eyes. After a while, the little boy turned around and prepared to leave: "No matter how much you cultivate, it's useless!"

"That's not necessarily!" Tsukiki and Inuzuka Qian walked out, and the girl said softly: "Other things can deceive people, but hard work will not." Those kids are working hard, and maybe they'll surprise us!"

"It's useless. The little boy glanced at the moon, shook his head, and slowly left.

"It's sad that the child must have gone through something that would have led him to lose faith in the future. Yura glanced at the little boy and withdrew his gaze, it has seen too many of this kind of hopeless people, and there is not so much time to save them one by one.

"Hey, you see, what's that girl's name? Chakra is very talented! Inuzuka Qian poked the moon breath and said.

"It's better to learn medical ninjutsu!" Tsukiki rolled her eyes and turned her attention to Sasuke and Naruto.
