Konoha Hospital.

Asma didn't look away at all, pushing the door like Kakashi's greeting.

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

Shikamaru smiled and looked at them: "How about Raiyin, Naruto, and Sakura, is the mission completed?"

Naruto slowly lowered his head.

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

Upon hearing this, Qiu Dao Dingci raised his hands in agreement: "Barbecue, okay!!"

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 on the opposite side and smiled like crazy.

Kakashi's eyelids drooped, as if not awake: "What's the matter?"

Naruto touched the back of his head and seemed a little embarrassed: "It's nothing, it's just that I haven't practiced with Teacher Kakashi for a long time, and I was a little excited for some reason."

Kakashi dropped a cold sweat.

Lei Yin didn't know when he came.

"Lei Yin?"

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

Kakashi smiled: "Of course, you can also guide Naruto if there is any deficiency, because I think your strength is far above mine."

Although this is telling the truth, Lei Yin doesn't want to admit: "Teacher Kakashi, you have passed the award."

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

This sentence, Naruto went to his heart, he lowered his head not knowing what he was thinking.

Suddenly, Kakashi turned his head and said, "Naruto, time waits for no one. This practice is to allow you to practice the strongest ninjutsu in your original creation, beyond Helix Maru's ninjutsu."

Naruto raised his head, and Kakashi continued: "These are the two techniques required to make Chakra'change of nature' and'change of form', neither of which is indispensable."

Naruto certainly didn't understand what it meant.

Kakashi continued to introduce.

Take'Chidori' and'Spiral Pill' as examples.'Chidori' belongs to Thunder Dun, which is a'change of nature', while'Spiral Pill' is a'morphological change' that compresses and rotates Chakra.

Naruto held his arms and squinted, with a thoughtful look: "Well, nature changes."

Lei Yin, who was sitting on the rock, thought to himself: This guy must not understand.

Kakashi continued: "If you want to practice ninjutsu beyond Helix Maru, you must master the'change of nature'!"

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

There was a drop of cold sweat on the back of Kakashi's head. He and Leiyin had the same idea.

Well, after all, it varies from person to person, Naruto is the kind of person who learns in practice.

The reason why Lei Yin wanted to listen to the'ceng class' was because he had a vague memory of this episode. If he wanted to listen to Kakashi's teaching with his own ears, it might be of some benefit to him.

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

Kakashi continued: "But it takes a lot of time to learn this technique. I thought of a way to significantly shorten the time."

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

"I won't sell it to you. The method is the'multiple shadow clone technique'! When the clone is released, it will be restored to the caster, and those experience points will be accumulated on the caster."

Rows of crows passed by on Naruto's head.

His cat's face narrowed into a slit, and he said nothing.

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

Naruto couldn't understand, of course Kakashi expected it.

Although Lei Yin understood it, 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 let Naruto split a clone too.

The shadows of the two walked into the woods.

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

Kakashi: "Wait a minute, you will know."

after awhile.

Kakashi tells Naruto to release the clone, and Naruto does.

When the clone was lifted, Naruto's body shook.

Kakashi: "How? Do you know it now?"

Naruto: "They are guessing, and I won."

Lei Yin suddenly realized!

However, Naruto's face was still puzzled: "But, even so, what does it have to do with shortening the training time?"

Kakashi was about to vomit blood: "I really lost to you, I will explain."

"Hurry up!" Naruto couldn't wait.

In fact, the truth is very simple.

After the two clones are lifted, the experience gained is twice that, so the time spent is half of the original.

For a thousand clones, the time spent is one thousandth!

This is definitely a shortcut to practice new techniques!

Kakashi said, Naruto's face suddenly opened up: "Suga, it turns out to be like this!"

"Then, the next step is to practice the'character change', using multiple shadow clones."

"Understand!" Naruto's face smiled brilliantly, "No wonder Mr. Kakashi, you are so strong, you have always used this method to practice."

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

Naruto was blinded in an instant: "Huh? Why? Isn't Kakashi teacher also able to shadow the avatar?"

Kakashi: "But, my chakra is not as much as you, and the shadow clone lasts for a short time. Because this technique requires an even distribution of chakras, people like me with less chakras are not suitable Surgery."

Naruto: "That means, I have more Chakra than Teacher Kakashi?"

Kakashi said with a straight face: "About four times as much as mine!"

"Four or four times?!"

"If the power of the Nine Tails is not suppressed, it will be more than a hundred times!"

Naruto was startled, but Kakashi's words startled him.

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

"Really? Huh? Where's Lei Yin?" Naruto looked around, but couldn't find Lei Yin, "He was sitting there just now."

St. Buddha Ridge.

Hearing what Kakashi said just now, Lei Yin seemed to have found a treasure.

With a move of mind, I came here.

If he practices in Konoha, he is afraid that it will cause unnecessary commotion.

Here, he is divided into ten thousand clones.

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

"But with this method"

These ten thousand avatars are all rotating chakra balls in their hands
