When Lei Yin practiced the 'Wind Thunder Shuriken', it took a long time to complete.

Knowing Kakashi's method, it should be possible to shorten the time a bit.

In the hands of these 10,000 shadow clones, the chakra ball rotated at high speed.

Now there are only wind attribute chakras.

Thunder Yin injected water attribute into it, just like when it was injected with thunder attribute.

Although he didn't feel that he had succeeded, he and more than 10,000 doppelgangers practiced it repeatedly.

In about ten minutes, he lifted the seal, and more than 10,000 clones disappeared.

He did feel different than before.

At the foot of this St. Buddha Ridge, clouds and mist shrouded it.

All around are dozens of people surrounded by thick and endless towering ancient trees.

This tree is called a fine iron tree, and not only does it have an endless lifespan, but its trunk is like steel.

"So, let's show the results."

As soon as Lei Yin's mind moved, the wind attribute chakra ball spun in his hand, and then, injected the water attribute into it.

The chakra in his hand is like a crystal ball spinning at high speed, and it looks extraordinarily colorful.

"Wind Escape: Iron Cannon Jade Spiral Shuriken!"

The energy ball swept the majestic wind pressure, hunting and hunting at the foot of the entire mountain, and it was enough to be launched with the momentum of a mountain and a tsunami.

Everywhere he passed, more than a dozen fine iron trees were blown open, and iron branches and iron leaves were scattered all over the ground.

On the ground, a hemispherical deep pit.

Seeing such power, Lei Yin shook his head slightly, it seemed that he felt that it was still a little unsatisfactory.

At the same time, in the forest of Konoha , Kakashi was still teaching Naruto seriously.

"So, only you are suitable for this cultivation method!"

At this moment, a voice came from behind him.

"Captain Yamato!"

Yamato was entrusted by Kakashi to teach Naruto together: "Thanks to Kakashi's seniors' trust, I came to help you complete your cultivation, because only I can suppress the power of the Nine-Tails." ”

"Then please!"

"Now, I'm going to explain the 'change in nature'."

Then, Kakashi explained it to him in detail.

There are five basic chakra properties, wind, fire, thunder, water, and earth. This is where the names of the five great ninja powers come from, and these five natures are also the basis of all ninjutsu. For example, the Uchiha clan has the property of 'fire', so they are particularly good at fire.

Naruto said, "So, Sasuke has two natures, 'fire' and 'thunder'? ”

"You're still equivalent to 'zero', and I don't know what kind of attribute you're good at." Kakashi said, his hand digging into his ninja bag and pulling out a small piece of paper, "Just use it to test it!" ”

"Oh?" Naruto's gaze was filled with curiosity.

Kakashi pinched the piece of paper with two fingers and poured chakra into it, and in an instant, the piece of paper became crumpled.

Naruto certainly didn't know what that meant.

Kakashi continued.

If it is a thunder attribute, the piece of paper will be wrinkled; wind attributes, the paper will crack; fire properties, paper will burn; water properties, the paper will be damp; If you use soil, the paper will break.

This paper is a type of paper that induces chakra, and is made from a special tree that absorbs chakra to obtain nutrients.

Kakashi handed the piece of paper to Naruto.

Naruto placed the piece of paper in his palm and injected chakra into it.

When I took it out again, the piece of paper was halved.

"Okay, then let's start the cultivation of the change in the nature of the wind attribute."

Naruto's cat face had a look of confusion: "Wind..."

Kakashi: "It's a chakra that can break everything and has superior combat power. ”

Naruto excitedly said, "Oh, I'm really amazing! ”

Kakashi's face was flat: "If you only know this, it's still early." ”

Yamato continued, "That's right, you have to cultivate hard to be able to grasp this nature flexibly. ”

Naruto: "That... I'd love to know if Captain Yamato belongs to that kind of change. ”

When Yamato heard this, his expression froze, and he made a gesture of sealing:

"Tu Dun, Tuliu City Wall!"

Suddenly, a huge crack appeared on the ground in front of Yamato, and then the crack broke, and the entire ground under his feet lifted up and became a platform dozens of meters high!

Naruto was startled and looked up at Yamato, "Wow, what's going on?" ”

Yamato didn't reply, and his hands were sealed again: "Water Escape, Waterfall Technique!" ”

A puddle of water erupted, creating a waterfall on top of the platform.

Yamato shows the chakra of water and earth attributes.

Naruto looked up at the waterfall and couldn't help but be a little stunned: "Huh? Why does Captain Yamato have two attributes? ”

Kakashi explained, "When you reach the upper ninja level, there are generally more than two chakras. ”

Naruto: "So, with the addition of 'Kido', aren't there three kinds of Captain Yamato?" ”

Yamato waved his hand: "No, there is no 'wood' in the basic attributes, it is derived from the two attributes of 'water' and 'earth'. ”

Kakashi: "If you can use two changes at the same time to generate the power of a new nature change, this can be regarded as a kind of 'blood inheritance boundary', you should know this, right?" ”

Naruto still seemed to understand and let out an 'um'.

"Okay, then... Practice begins! First of all, we must grasp the change in the nature of the wind attribute! ”

Naruto looked scrappy: "What should I do?" ”

Kakashi plucked a leaf from the tree: "Sandwich it between your palms and cultivate until you can split it in two." ”

"Good! So let's get started! ”

"As I said, the more clones you have, the more experience points you will accumulate."

"The Technique of Multiple Shadow Clones!"

In an instant, Naruto's clone was already standing around.

Each flying body has a leaf in its palm.

Concentrate on injecting chakra into it...

St. Fernandes.

At this time, there seemed to be four red tails looming behind Lei Yin's strands, and the temperature around him intensified, and the air blowing was gusts of hot wind.

If it were an ordinary person here, I am afraid it would not last half a second.

The energy cyclone on Lei Yin's hand rotated at high speed, sometimes turning red, sometimes turning pale red.

He is mobilizing the power of the four-tailed Monkey King to integrate the dissolution into the 'Spiral Shuriken'.

The wind will make the dissolving power with the fire attribute even stronger.

Therefore, this cultivation process is rare beyond imagination.

In the fine iron forest, there were more than 10,000 clones of Lei Yin.

The iron branches and iron leaves were also roasted red.

The movements of each one are almost identical.

The consumption of a large amount of chakra, as well as the unbearable high temperature around him, even Lei Yin's half-immortal body was left sweating.

Beads of sweat dripped down the ground, all of which quickly turned into steam.

"The power of this 'dissolution' is really not to be underestimated, and it can be compared to the red dogs of the pirate world."

Lei Yin wiped the sweat from his face and muttered.

The temperature in the vicinity is like a lava hell.

But for Lei Yin, it's like soaking in a hot spring...
