Konoha Hospital.

Asma didn't see it at all, pushing the door like Kakashi saying hello.

Ino was a little dissatisfied with the teacher's behavior: "Teacher, you should knock on the door first, right?" ”

Shikamaru looked at them with a smile: "Thunder, Naruto, and Sakura, how is it, is the mission completed?" ”

Naruto slowly lowered his head.

Of course, everyone understood what was going on, and laughed out loud to ease the embarrassment: "Don't think about it so much, I'll invite everyone to eat barbecue, if you don't mind, Kakashi will come too!" ”

Hearing this, Akido Dingji raised his hands in approval: "Barbecue, yes!" ”

So, Asma took everyone to eat barbecue, but Naruto was still thinking about cultivation...

The next day, inside a forest in Konoha.

Naruto looked at Kakashi across from him, smiling like a psychopath.

Kakashi's eyelids drooped, as if he hadn't woken up, "What's wrong?" ”

Naruto touched the back of his head, seeming a little embarrassed, "No... It's nothing, it's just that I haven't practiced with Kakashi-sensei for a long time, and I'm inexplicably a little excited..."

Kakashi broke out in a cold sweat.

Lei Yin didn't know when it came.

"Lei Yin?"

"If you don't mind, can I take a look here?" Lei Yin said.

Kakashi smiled, "Of course, if there are any shortcomings, you can also guide Naruto, because I think your strength... Far above me. ”

Although this was true, Lei Yin didn't want to admit it, "Kakashi-sensei, you have won the award. ”

After speaking, Lei Yin found a rock not far away and sat down.

[Lei Yin's strength... Is it far above Kakashi-sensei? 】

Naruto said this, but he went to his heart, he lowered his head and didn't know what he was thinking.

Suddenly, Kakashi turned his head: "Naruto, time waits for no one, this cultivation is for you to practice the strongest ninjutsu of your originality, surpassing the ninjutsu of Spiral Pill." ”

Naruto looked up, and Kakashi continued, "These are the two techniques that require chakra's 'change of nature' and 'change of form', and one is indispensable. ”

Naruto, of course, didn't understand what it meant.

Kakashi continued.

Take 'Chidori' and 'Spiral Pill' as examples, 'Chidori' is a thunderbolt and is a 'change of nature', while 'Spiral Pill' is a 'change of form' that compresses and rotates the chakra.

Naruto crossed his arms and squinted his eyes with a thoughtful look: "Hmm... change in nature..."

Lei Yin, who was sitting on the rock, thought to himself: This thing must not have understood.

Kakashi continued, "If you want to practice ninjutsu that surpasses Spiral Pill, you must master the 'Nature Change'!" ”

Naruto smashed his fist on the palm of his hand: "Oh, Soga, then learn 'Nature Change'!" ”

Kakashi had a drop of cold sweat on the back of his head, he and Rayin had the same thoughts.

Well, after all, it's different from person to person, and Naruto is the kind of person who learns by doing.

And the reason why Lei Yin wanted to come to 'skip class' to listen was because his memory of this episode was a little vague, and he wanted to come and listen to Kakashi's teaching, maybe it would be beneficial to him.

Rayin's IQ is different from Naruto's, and now he has some ideas of his own.

Kakashi continued, "But it takes a lot of time to learn this technique, and I thought of a way to drastically reduce it. ”

Upon hearing this, Naruto instantly excited: "Really? Is there a way to reduce the time? ”

"I won't sell it to you, the method is the 'Multiple Shadow Clone Technique'! When the clone is disarmed, it is restored to the caster, and those experience points accumulate towards the caster. ”

On Naruto's head, rows of crows swept by.

His cat face narrowed into a slit and didn't say a word.

After a while, he said to Kakashi, "CC, can you make it simpler. ”

Naruto didn't understand, which was certainly something Kakashi expected.

[If only I could understand it, it would be strange.] 】

Although Lei Yin understood, he didn't think it would have much effect.

But he listened very carefully, for fear of missing a word.

Kakashi split a shadow clone, and he made Naruto split a clone as well.

The shadow clones of the two walked into the woods.

The two couldn't see what they were doing at all, and Naruto was curious.

Kakashi: "Wait a minute, you'll see." ”

After a while.

Kakashi asks Naruto to disarm the clone, and Naruto does so.

The moment the clone was lifted, Naruto's tiger body was shocked.

Kakashi: "How's it going?" Now you know? ”

Naruto: "They're guessing punches, and I won." ”

Lei Yin suddenly realized!

However, Naruto's face was still puzzled: "But, even if that's the case, what does that have to do with shortening the cultivation time?" ”

Kakashi was about to vomit blood: "It's really a defeat for you, I'll explain it." ”

[How did Zilai also teach this 'spiral pill'? ] 】

"Hurry up, hurry up!" Naruto looked impatient.

Actually, it's very simple.

When the two clones are disarmed, they gain twice as much experience, and the time spent is half as long.

A thousand doppelgangers take one thousandth of the time!

This is definitely a shortcut to cultivating a new technique!

Kakashi said this, and Naruto's face suddenly brightened: "Soga, so that's it!" ”

"Then, the next step is to carry out the cultivation of 'nature change', using multiple shadow clones."

"Understood!" Naruto's face smiled brightly, "No wonder Kakashi-sensei you are so strong, it turns out that you have always used this method to cultivate. ”

Kakashi looked lazy: "No, I haven't used this method once!" ”

Naruto was instantly blindsided: "Huh? Why? Isn't Kakashi-sensei also capable of shadow clone techniques? ”

Kakashi: "However, my chakra is not as long as yours, and the shadow clone lasts for a short time. Because this technique requires an equal distribution of chakras, people like me who have fewer chakras are not suitable for this technique. ”

Naruto: "That means my Chakra-sensei is more than Kakashi-sensei?" ”

Kakashi grimaced: "About four times as much as me!" ”

"Four... Fourfold?! ”

"If you don't suppress the power of the 'Nine-Tails', it will be more than a hundred times!"

Naruto was stunned, and Kakashi's words startled him.

"So, this method is very suitable for your cultivation."

"Really? Hey? What about Lei Yin? Naruto looked left and right, but couldn't find Reiin's figure, "He was still sitting there just now..."

St. Fernandes.

After listening to Kakashi's words just now, Rayin was like picking up a treasure.

My mind moved, and here I am.

If he cultivated in Konoha, he was afraid that it would cause unnecessary commotion.

Here, he divided 10,000 doppelgangers.

If the water attribute chakra is injected directly into the 'Spiral Shuriken', then I don't know how long it will take to master.

"However, in this way..."

These 10,000 doppelgangers, all with spinning chakra balls in their hands...
