After getting rid of Toad Wentai, Xu Fan simply changed the conversation and brought the topic back to business.

Seeing that nothing was going on here, Shima continued to go back and happily prepare lunch.

The toads that gathered here were also dispersed a lot.

"Okay, then let's learn immortal arts."

Fukasaku took a deep breath and began to explain what immortal arts are and how to use them.

The so-called immortal art is to use the energy of nature for one's own use.

And if you want to absorb the energy of nature, you must first become a part of nature.

"But before that, it's worth showing you the power of natural energy."

After saying this, he directly absorbed the natural energy around him, and then lifted the huge stone statue beside him.

Judging from the size alone, this stone statue is at least hundreds of times deeper.

Not to mention, this statue is still made of stone.

Of course, Xu Fan was naturally not surprised by this scene.

After using immortal arts, all aspects of the body's attributes will be greatly improved.

Naruto, on the other hand, was shocked by the scene in front of him and couldn't speak.

Even after Fukasaku put down the stone statue, Naruto deliberately trotted over and tried to pick it up.

The results can be imagined.

The lightest stone statue here is probably measured in tons.

"However, ordinary people can't even feel it, let alone absorb natural energy."

Fukasaku said as he jumped near the Toad Oil Falls.

Xu Fan and Naruto followed.

On the contrary, he simply sat cross-legged on the ground, began to flip through the collected materials, and then started to create.

If it weren't for the face of Lord Fukasaku, Jiraiya would even want to slip away directly.

After all, when it comes to teaching immortal arts, the experience of Lord Fukasaku is even deeper than himself.

To prevent the Nine-Tails from going berserk, Xu Fan's Mu Dun was easier to restrain the Nine-Tails than his own seal.

It's not there, but it doesn't really matter.

"Therefore, the first time you perceive natural energy, you must use the toad oil of Miaomu Mountain, which can help you perceive natural energy and absorb it."

"But ......"

Fukasaku's voice suddenly sank, and it instantly became extremely serious, he looked at the toad statues around him, and continued, "Once you absorb too much natural energy, you will turn into a stone statue, and you will never recover. ”

"The stone statues you see are all people who have failed to learn immortal arts."

As soon as Fukasaku said this, Naruto's whole person was taken aback.

Although he really wanted to learn immortal arts, he didn't want to turn into stone.

"Of course, I'm not going to allow that to happen."

Suddenly, Fukasaku smiled and pulled out a black, hard stick from behind him, waving it as he explained.

Once he absorbs too much natural energy, he will swing his stick and knock the natural energy out of Naruto's body.

That way, Naruto wouldn't be turned into a stone statue.

"Isn't it going to hurt......"

Naruto looked at the black rod in Fukasaku's hand, and the corners of his mouth couldn't help but gasp.

"It does hurt, so ...... If Naruto wanted to, he could do that. Fukasaku said without thinking about it.

Although the Great Toad Immortal had agreed to Naruto's study of senjutsu, Fukasaku did not intend to put pressure on Naruto to force him to learn.

Now he is still a child after all, even if he grows up a little more, it doesn't matter.

Xu Fan also gently touched Naruto's head, telling him that there was nothing wrong with giving up here.

Anyway, I've already completed the check-in.

"No ......"

Naruto, however, shook his head firmly.

If you want to see your parents, you must enter the inner world and face the Nine-Tails.

This will inevitably require sufficient strength.

If you waste an extra day, you will see your parents a day later.

"Come on, Grandpa Fukasaku!"

Naruto took a brave step forward, his hands clenched into fists, and said in a loud but powerful voice.

Fukasaku looked at Naruto in front of him, and his heart became more and more fond of this human child.

"So...... Here we go. ”

Fukasaku said as he smeared toad oil on Naruto's arm.

Because there was only one black rod, Fukasaku didn't let Naruto and Xu Fan try at the same time.

Naruto also took a large breath, trying to absorb the natural energy around him, as Fukasaku had said.

Soon, Naruto's body began to swell, and frogification appeared.

Boom!

Worried that Naruto would turn into a stone statue, Fukasaku jumped up from the ground and swung a black rod into Naruto's head.

"Ahh

Naruto couldn't help but scream, and then sat down on the ground with a thud, his hands couldn't help but rub the place where he had been hit by the black rod.

"It hurts."

Naruto couldn't help but say.

"Of course, if you want to master immortal arts, it's not so easy, and it took Xiao Zilai a few years to learn it."

Fukasaku directly uses Jiraiya as an example.

Fukasaku didn't finish his sentence, though.

Even now, Jiraiya's immortal mode is not so perfect.

While absorbing natural energy, his body will still have a noticeable frogification.

"So you two, it's better to do a good job of psychological construction for a few years."

Fukasaku turned his head to look at Xu Fan.

Now that Naruto has already had his first time, it is time for Xu Fan to experience the feeling of natural energy.

"But...... I have something I have to say. ”

Fukasaku suddenly became several times more serious than when he faced Naruto.

"Huh?"

Xu Fan frowned slightly, he knew Shenzuo and immortal art very well.

What I just said to Naruto should be all about senjutsu.

What else is worth elaborating?

"The so-called immortal chakra is actually the fusion of the three energies of body, spirit, and nature, in a certain proportion."

"Usually, it's one to one."

After hearing Fukasaku's voice, Jiraiya, who was in the middle of the creation, suddenly stood up from the ground, as if he realized something.

"Xu Fan ......"

Zilai also lowered his voice and walked quickly to Xu Fan's side.

Instead, Naruto looked at the few people in front of him in confusion, not quite understanding what was going on.

"So...... To enter Immortal Mode, you must first absorb enough natural energy......"

Fukasaku couldn't help but look at the black rod in his hand.

Thinking of the chakra that Xu Fan had just erupted from, Fukasaku himself was not very sure whether this small black rod would absorb too much natural chakra and beat it all out of Xu Fan's body.

In other words, Xu Fan's risk of becoming a stone statue was more than a little higher than Naruto's.

"Xiao Xu Fan, if you want to give up now, it's still too late."

Fukasaku rolled his throat and said his advice to Xu Fan.

"Give up?"

Xu Fan couldn't help muttering, and then shook his head, "That's too boring." "Diagram of the Great Dao of the Heavens
